Seyyed Hossein Nasr

Seyyed Hossein Nasr (, born April 7, 1933) is an Iranian-American philosopher, theologian and Islamic scholar. He is University Professor of Islamic studies at George Washington University.

Born in Tehran, Nasr completed his education in Iran and the United States, earning a bachelor's degree in physics from Massachusetts Institute of Technology, a master's in geology and geophysics, and a doctorate in the history of science from Harvard University. He returned to his homeland in 1958, turning down teaching positions at MIT and Harvard, and was appointed a professor of philosophy and Islamic sciences at Tehran University. He held various academic positions in Iran, including vice-chancellor at Tehran University and President of Aryamehr University, and established the Imperial Iranian Academy of Philosophy at the request of Empress Farah Pahlavi, which soon became one of the most prominent centers of philosophical activity in the Islamic world. During his time in Iran, he studied with several traditional masters of Islamic philosophy and sciences.

The 1979 revolution forced him to exile with his family to the United States, where he has lived and taught Islamic sciences and philosophy ever since. He has been an active representative of the Islamic philosophical tradition and the perennialist school of thought.

Nasr's works offer a critique of modern worldviews as well as a defense of Islamic and perennialist doctrines and principles. Central to his argument is the claim that knowledge has become desacralized in the modern period, meaning that it has become severed from its divine source – God or the Ultimate Reality – which calls for its resacralization through the utilization of sacred traditions and sacred science. Although Islam and Sufism are major influences on his writings, his perennialist approach inquires into the essence of all orthodox religions, regardless of their formal particularities. His environmental philosophy is expressed in terms of Islamic environmentalism and resacralization of nature. He is the author of over fifty books and more than five hundred articles.

Origins
Seyyed Hossein Nasr was born on 7 April 1933 in Tehran to Seyyed Valiollah Nasr, who was a physician to the royal family, philosopher and homme de lettres, and one of the founders of modern education in Iran. Nasr's parents were originally from Kashan. His mother was well-versed in Persian literature and poetry. He is a descendant of Sheikh Fazlollah Nouri from his mother's side, is the cousin of Iranian philosopher Ramin Jahanbegloo as well as the father of American academic Vali Nasr.

The surname "Nasr", which means "victory", was given to his grandfather by the Shah. The title "Seyyed" indicates a descendant of the Prophet Muhammad.

Education
Nasr completed his primary education in Tehran. His education was supplemented by religious and philosophical discussions with his father and an entourage of theologians, ministers, scholars, and mystics. He immersed himself in the Koranic studies, Persian literature, Arabic and French languages at an early age. While he was completing his first year of secondary school at Firooz Bahram High School, his father was hurt in a serious accident, so his mother sent him to continue his education in the United States so that he would not be present at the time of his father's imminent death. He would later say that there are three things that his father left him: "first of all, love of knowledge for our own Persian culture, our religious, literary, philosophical tradition; secondly, an avid interest in what was going on in the West in the realm of science and philosophy, literature and everything else; thirdly, a sense of serenity that he had within himself."

In the United States, Nasr first attended Peddie School in Hightstown, New Jersey, graduating in 1950 as the valedictorian of his class.

He then applied to the Massachusetts Institute of Technology in Boston to study physics and was accepted with a scholarship. When he realized, after an encounter with the philosopher Bertrand Russell, that the study of physics would not bring answers to his questions, he enrolled in additional courses on metaphysics and philosophy with Giorgio de Santillana who introduced him to the works of René Guénon. From there, Nasr discovered the works of other Perennialist metaphysicians, notably Frithjof Schuon, Ananda Coomaraswamy, Titus Burckhardt, Martin Lings, and Marco Pallis. This school of thought has shaped Nasr's life and thinking ever since. The widow of Commaraswamy gave him access to the library of her late husband, and Nasr spent much of his time there and worked to catalogue the library. He visited Schuon and Burckhardt in Switzerland while still a student and was initiated into the Alawi branch of the Shadhili Sufi order. He considered the works of Schuon, with central importance given to the practice of a spiritual discipline in addition to doctrinal knowledge, especially instrumental in determining his intellectual and spiritual life.

After receiving an MIT B.S. degree in physics in 1954, Nasr enrolled in the graduate program in geology and geophysics at Harvard University, where he received a Master of Science in both fields in 1956, and went on to pursue his PhD degree in the history of science and learning at the same university. He planned to write his dissertation under the supervision of George Sarton, but Sarton died before he could begin his dissertation work and so he wrote it under the direction of I. Bernard Cohen, Hamilton Gibb, and Harry Wolfson.

At the age of twenty-five, Nasr graduated with a PhD from Harvard and completed his first book, Science and Civilization in Islam, the title being a direct tribute to Science and Civilization in China, the work by Joseph Needham which had for task to present to Westerners the complex developments of the history of science and technology in China, a mission Nasr was himself following for the Islamic civilization. His doctoral dissertation entitled "Conceptions of Nature in Islamic Thought" was published in 1964 by Harvard University Press as An Introduction to Islamic Cosmological Doctrines.

Apart from mastering Arabic and French he was initially taught in his childhood, during his student years, Nasr also learned Greek, Latin, Italian, Spanish and German.

Back to Iran
After receiving his Ph.D. from Harvard in 1958, Nasr was offered the position of associate professor at MIT, as well as a three-year research position as a junior fellow followed by a formal teaching position at Harvard, but he decided to return to Iran. That same year, Tehran University hired him as associate professor of philosophy and the history of science. He continued his study of Islamic sciences with traditional Iranian masters and philosophers (Muhammad Husayn Tabataba'i, Allameh Sayyed Abul Hasan Rafiee Qazvini and Sayyid Muhammad Kazim Assar), completing his dual education, academic and traditional.

He had married and started a family at this point. His son, Vali Nasr, would go on to become an academic and expert on the Islamic world.

At thirty, Seyyed Hossein Nasr was the youngest person to become a full professor at Tehran University. He was quickly recognized as an authority in Islamic philosophy, Islamic science and Sufism. For fifteen years he conducted a doctoral seminar in comparative philosophy and Islamic philosophy with Henry Corbin who was at that time the director of the French Institute for Iranian Studies in Tehran. Five years later he would be made the dean of the faculty of letters and then vice-chancellor of the university.

In 1972, the Shah chose him to become the President of Aryamehr University (now Sharif University of Technology). There, Nasr created a faculty for the humanities in order to encourage the students not to focus exclusively on scientific matters. He also designed courses that focused on the assessment of modern technology and its impact on human society and the environment. During this time, he was also involved in the creation of the Islamic and Iranian studies departments at Harvard, Princeton, the University of Utah, and the University of Southern California.

"I belonged to a new generation and was able to exercise much influence not only at Tehran University but also in the cultural and educational life of the country as a whole since I was a member of all the important national councils in those fields, […] So there was a really formidable jihād on my hands to try to turn things around and to make Iranian society more aware of its own heritage. I tried to create a bridge between the traditional and the modern elements of our society. (interview)"

Nasr refused to engage in the politics of his country despite a number of offers for ministerial positions and ambassadorship. In 1974, Empress Farah Pahlavi commissioned him to establish and lead the Imperial Iranian Academy of Philosophy (now the Institute for Research in Philosophy), the first academic institution to be conducted in accordance with the intellectual principles of the Traditionalist School. During that time, Nasr, Tabataba'i, William Chittick, Peter Lamborn Wilson, Kenneth Morgan, Sachiko Murata, Toshihiko Izutsu, and Henry Corbin held various philosophical discourses. The book Shi'ite Islam and the traditionalist journal Sophia Perennis were products of this period. In 1978, he was named director of the Empress's private bureau, while continuing to teach philosophy at Tehran University, and serve as chancellor of Aryamehr University, and President of the Imperial Iranian Academy of Philosophy.

Return to the West
In January 1979, the revolution put an end to the Pahlavi dynasty and Nasr, who was visiting London with his family at the time, was unable to return to Iran. He lost everything, including his manuscripts and library. His family settled in Boston. After a few months of teaching at the University of Utah, Nasr was appointed a professor of Islamic studies at Temple University in Philadelphia, which had the largest Ph.D. program in religious studies in the United States.

During the 1980–1981 academic year, Nasr delivered the Gifford lectures at the University of Edinburgh, which were later published under the title Knowledge and the Sacred. According to William Chittick, "three out of the four of his first books in English (An Introduction to Islamic Cosmological Doctrines, Three Muslim Sages, and Science and Civilization in Islam) were published by Harvard University Press, and they immediately established him as one of the major and original voices in Islamic studies. His strong endorsement of the writings of Schuon and Burckhardt in these books were in turn instrumental in bringing the Traditionalist school to the notice of official academia".

Nasr left Temple University in 1984 to become a professor of Islamic studies at George Washington University in Washington, D.C., a position he holds to this day. That same year, he established the Foundation for Traditional Studies which published the journal Sophia and works on traditional thought. He has authored over fifty books and over five hundred articles based on the principles of the philosophia perennis. He is regularly invited to give courses and conferences at various institutions and universities of the five different continents on the major themes for which he has become well known: Islam, philosophy, metaphysics, cosmology, anthropology, spirituality, religion, science, ecology, literature, art, etc. His works have been translated into twenty-eight different languages.

Notable aspects of his works
Nasr's expertise encompasses traditional culture (wisdom, religion, philosophy, science and art), Western thought from antiquity to the present day, and the history of science. He argues in favor of revelation, tradition, and what he considers "scientia sacra", in opposition to rationalism, relativism, and modern western materialism. Nasr has not developed a new system of thought, but instead hopes to revive traditional doctrines that he believes have been forgotten in the modern world. He is content to recall what, according to him, corresponds to the many manifestations of a timeless wisdom. Although Islam and Sufism are present throughout his writings, his universalist perspective, which is that of perennial philosophy, takes into account what he assumes to be the common essence of all orthodox religions beyond their formal particularities or their current state: "My philosophical world is a kind of synthesis between the perennial philosophy, which I espouse and represent, and the Islamic philosophical tradition, which I have tried to revive and to which I also belong. And so I would say that for the first category, there are Guénon and Schuon; if I had to name a third person, then Coomaraswamy; and for the second category, Ibn Sina, Suhrawardı, Ibn Arabi, and Mulla Sadra." According to Sarah Robinson-Bertoni, Nasr is one of the principal figures in Islamic philosophy, working at the crossroads of Western and Islamic intellectual traditions.

Harry Oldmeadow considers Nasr to be "of the living traditionalists the most widely known in academic circles". For him, Nasr's works are characterized by "rigorous scholarly methodology, an encyclopedic erudition about all matters Islamic, a robustness of critical thought, and a sustained clarity of expression"; and he is "the foremost traditionalist thinker" to base himself on "eternal wisdom (sophia perennis)" in order to provide a solution to the contemporary environmental crisis.

The Perennialist or Traditionalist school
When he discovered the writings of the most influential members of what would become the Traditionalist or Perennialist school (René Guénon, Frithjof Schuon, Ananda Coomaraswamy, Titus Burckhardt, Martin Lings), the student Seyyed Hossein Nasr fully aligned himself to their perspective founded on the philosophia perennis.

"I had discovered a worldview about which I felt complete certitude (yaqın). I felt that this was the truth that satisfied me intellectually and accorded with my life existentially. It was in harmony with the faith that I had. It was universalist in its metaphysical perspective and also critical of Western philosophy and science in a manner that spoke directly to my concerns. (interview)"

Thus, in the middle of a "materialistic century", this School provides Nasr with the keys to his spiritual quest: an esoteric doctrine and method within the framework of a Sufi path. For Patrick Laude:

"...Seyyed Hossein Nasr's background is remarkable in at least three ways: first, he is a public figure who has been widely recognized in the media – in both the US and Europe – as a spokesman for perennialist ideas. [...] Second, he is the only perennialist writer who is closely identified with a given religious tradition, both as being born in it and as being a world expert on many of its dimensions. [...] Thirdly, Nasr is the only foremost perennialist writer to have received an intensive and advanced academic training in modern sciences. [...] His familiarity and identification with Islam, his validation as a recognized scholar and respected member of the scholarly community, and his conceptual proficiency in modern scientific languages have all contributed to make him a particularly apt interpreter of perennialist ideas in the contemporary public arena."

For Nasr, the expression, "philosophia perennis", as understood by the Perennialist School refers to both the universal metaphysical truth and to its spiritual realization. The latter can only be considered, according to Nasr, in the framework of a tradition, thus with the aid of a method, rites, symbols and other means sanctified by revelation. The truth, though veiled, is innate to the human spirit and its realization leads to what he calls "knowledge", that is to say gnosis or wisdom (sophia), hence the expression "sophia perennis", common ground at the heart of all religions. Nasr clarifies that the notion of the philosophia perennis does not derive from a compilation "of wisdom writings of various historical traditions", which would have resulted in the conviction of the existence of common truths, but it is these very truths which, by "the practice of intellection, the use of the intellect" understood in a spiritual manner, are revealed to the human spirit which then observes "their presence in other times and climes and in fact in all the sacred traditions the world over". The language of the perennial philosophy is symbolism.

God and the world
According to Seyyed Hossein Nasr, the "Divine Reality" includes, metaphysically speaking, an "Impersonal Essence" and a personal aspect that the believer "ordinarily identifies with God", in accordance with the perspective of "most religions". Only the "esoteric dimension" within these religions take into account the "Impersonal Essence", as can be seen most notably in "the Kabbalah, Sufism, and among many Christian mystics such as Meister Eckhart and Angelus Silesius". "God as ultimate Reality" is thus at the same time "Essence" and "Person" or "Supra-Being and Being". Understood in this way, God or the Principle,

"is Reality in contrast to all that appears as real but which is not reality in the ultimate sense. The Principle is the Absolute compared to which all is relative. It is Infinite while all else is finite. The Principle is One and Unique while manifestation is multiplicity. It is the Supreme Substance compared to which all else is accident. It is the Essence to which all things are juxtaposed as form. It is at once Beyond Being and Being while the order of multiplicity is comprisedof [sic] existents. It alone is while all else becomes, for It alone is eternal in the ultimate sense while all that is externalized partakes of change. It is the Origin but also the End, the alpha and the omega. It is Emptiness if the world is envisaged as fullness and Fullness if the relative is perceived in the light of its ontological poverty and essential nothingness. These are all manners of speaking of the Ultimate Reality which can be known but not by man as such. It can only be known through the sun of the Divine Self residing at the center of the human soul."

God is not only "Absolute and Infinite", He is also "the Supreme Good or Perfection". Now, according to Nasr, the specificity of infinitude and of good in divinis requires that they exteriorize themselves, that is to say, that they manifest themselves in multiplicity, hence the world. A world that is imperfect despite the perfection of its source because, as Nasr explains, this exteriorization implies a distance from the "Good", hence the presence of evil; the latter, contrary to the good, does not have its root in God. This "imperfect world" – the visible and tangible world of man – constitutes only the periphery of a hierarchy of increasingly subtle "worlds" according to their degree of proximity to Being.

For Nasr, God is the only reality, and the world, which participates in His reality is therefore "unreal", not as "nothingness pure and simple" but as "relative reality"; it is an illusion to consider the world, says Nasr, as "reality" in the same way as the Principle. Nasr holds that traditional wisdom or the sophia perennis "has always seen God as Reality and the world as a dream from which the sage awakens through [spiritual] realization [...] and the ordinary man through death". To consider the world as "the reality, [...] as is done by most modern philosophy [...] leads to nihilism and skepticism by reducing God to an abstraction, to the 'unreal', and philosophy itself to the discussion of more or less secondary questions or to providing clever answers to ill-posed problems".

For Nasr, "Ultimate Reality" is at once "above everything" and "omnipresent" in the universe, "transcendent and immanent". On the human plane, still according to Nasr, "The Reality" – or "The Truth" – lies in the heart of man "created in the image of God", whence the possibility of a "unitive knowledge which sees the world not as separative creation but as manifestation that is united through symbols and the very ray of existence".

The human being
"The key to the understanding of the anthrōpos", according to Nasr, is situated in "sapential teachings"; it is neither situated in "exoteric religious formulations", which relate essentially to "salvation", nor in what he considers to be "profane" science, generally evolutionary. Beyond his faith in "creationism ex nihilo" Nasr believes that the doctrines "of all traditions" attest that "the genesis of man, occurred in many stages: first, in the Divinity Itself so that there is an uncreated 'aspect' to man", hence the possibility of "supreme union"; then "in the Logos which is in fact the prototype of man and another face of that same reality which the Muslims call the Universal Man and which each tradition identifies with its founder"; after this, "man is created on the cosmic level and what the Bible refers to as the celestial paradise where he is dressed with a luminous body"; "he then descends to the level of the terrestrial paradise and is given yet another body of an ethereal and incorruptible nature"; finally, "he is born into the physical world with a body which perishes" but he principially remains a reflection of "the Absolute not only in his spiritual and mental faculties but even in his body".

Thus, Nasr rejects biology's modern evolutionary synthesis, which he thinks is a "desperate attempt to substitute a set of horizontal, material causes in a unidimensional world to explain effects whose causes belong to other levels of reality". For Nasr, in accordance with "the traditional view of the anthrōpos", the human being is a "bridge between Heaven and earth (pontifex)". Responsible to God for his actions, he is the custodian and protector of the earth, "on the condition that he remain faithful to himself as the central terrestrial figure created in the 'form of God', [...] living in this world but created for eternity". This aspect of humanity, for Nasr, "is reflected in all of his being and his faculties".

Among these faculties, Nasr underlines the primacy of intelligence, sentiments, and will: "as a theomorphic being", his intelligence "can know the truth as such", his sentiments "are capable [...] of reaching out for the ultimate through love, suffering, sacrifice, and also fear", and his will "is free to choose [...], it reflects the Divine Freedom". But, "because of man's separation from his original perfection", a consequence "of what Christianity calls the fall", itself followed by further declines, these faculties no longer operate invariably according to their "theomorphic nature". Thus, "intelligence can become reduced to mental play", "sentiments can deteriorate to little more than gravitation around that illusory coagulation which [...] is the ego" and "the will can be debased to nothing other than the urge to do that which removes man from the source of his own being".

"All traditional sciences of nature, [...] are also sciences of the self on the basis of the microcosmic-macrocosmic correspondence", therefore by virtue of an "inward link that binds man as the microcosm to the cosmos". This ideal man, underlines Nasr, is "primordial man [...] perfect, [...] plenary reflection of all those Divine Qualities", who knew everything "in God and through God".

Knowledge and the intellect
According to Seyyed Hossein Nasr, "man contains within himself many levels of existence", that "the Western tradition" synthesises in the ternary "spirit, soul, and body (pneuma, psychē, and hylē or spiritus, anima, and corpus". "The human spirit is an extension and reflection of the Divine Spirit", it coincides with the "intellect" and "resides at the center of the spiritual heart" of the human being. Nasr always uses the word "intellect" in "its original sense of intellectus (nous)" and not "of reason (ratio)", which is only its "reflection" and which "is identified with the analytical functions of the mind"; "the intellect is the light of the sacred shining upon our minds".

The intellect, which "is the root and the center of consciousness" is also "the source of inner illumination and intellection", which Nasr, following Guénon, also calls "intellectual intuition", and that implies an "illumination of the heart and the mind of man", making possible a "knowledge of an immediate and direct nature, [...] tasted and experienced", which extends to "certain aspects of reality" up to "the Absolute Reality". The human intellect is "the subjective pole of the Word or of the Logos – the universal Intellect – by which all things were made and which constitutes the source of objective revelation, that is to say, formal and established religion". For Nasr, in the vast majority of cases, this "inner revelation", or intellection, cannot become operative except by virtue of an external revelation which provides an objective cadre for it and enables it to be spiritually efficacious", hence the necessity of faith and spiritual practices associated with the realization of the virtues, with the aid of the grace issuing from each revelation.

Huston Smith summarises in an analysis of Nasr's works, that Nasr contends it is "God who knows Himself" through man. For Nasr, indeed, "discrimination between the Real and the unreal terminates in the awareness of the nondual nature of the Real, the awareness which is the heart of gnosis and which represents not human knowledge but God's knowledge of Himself", consciousness which is at the same time "the goal of the path of knowledge and the essence of scientia sacra". Nasr contends that this wisdom, which corresponds – beyond salvation -– to deliverance from the bonds of all limitation, "is present in the heart of all traditions", whether it be the Hindu Vedanta, Buddhism, the Jewish Kabbalah, the Christian metaphysics of an Eckhart or an Erigena, or Sufism. It alone "is able to solve certain apparent contradictions and riddles in sacred texts".

"Through such sacred knowledge, man ceases to be what he appears to be to become what he really is in the eternal now and what he has never ceased to be."

The sacred
Terry Moore, in his introduction to a long interview that Seyyed Hossein Nasr gave to the Iranian philosopher Ramin Jahanbegloo, recalls that for Nasr,

"the Sacred is the Eternal Absolute Truth as It manifests Itself in our world. It is the appearance of the Eternal in time, the Center in the periphery, of the Divine in the world of space and time. The Sacred is present in Itself and in Its manifestations."

Still, according to Moore, it is this relationship with the sacred, through the channel of "Tradition" that anchors Seyyed Hossein Nasr's worldview. Nasr considers the sense of the sacred as inseparable from any spiritual quest. This sense emanates from the awareness of the eternal and immutable reality of the Divine, which is both transcendent and immanent to all universal manifestation, therefore also to the human being. The sacred manifests itself in "revelation, the sacred rites of various religions, spiritual and initiatory practices, sacred art, virgin nature", in fact everything that transmits "the presence of the Divine".

"It is possible for us to rediscover the sacred character of both knowledge and the world, and one might say that that has been the basic motif throughout my writings."

Metaphysics
For Nasr, true metaphysics – the scientia sacra –, which is the intellectual foundation of the Traditionalist School, "is the science of the Real; of the origin and the end of things; of the Absolute and in its light, the relative" and, as a corollary, of the degrees of existence. It is therefore:

"the knowledge by means of which man is able to distinguish between the Real and the illusory and to know things in their essence or as they are, which means ultimately to know them in divinis. The knowledge of the Principle which is at once the absolute and infinite Reality is the heart of metaphysics while the distinction between levels of universal and cosmic existence, including both the macrocosm and the microcosm, are like its limbs. [...] metaphysics is the primary and fundamental science or wisdom which [...] contains the principles of all the sciences." True metaphysics, underlines Nasr, can only be assimilated by intellectual intuition, that is to say that it is necessarily associated with a path of spiritual realization, an approach foreign to modern philosophy, which has been instrumental in reducing the significance of metaphysics to just another mental activity. Metaphysical knowledge stems from the true understanding of symbolism.

Religion and spirituality
According to Nasr, man is "a theomorphic being living in this world but created for eternity" because his "soul is immortal". The post-mortem salvation of the soul, reminds Nasr, is "the first duty of man", according to every religion, – a soul tainted here below by its "centrifugal tendencies", its "passions".

Nasr contends that all religions have an origin in God, reveal the paths which "leads to either felicity in the hereafter or damnation, to the paradisal or infernal states", and require "faith".

Each new "descent" of a revelation brings a particular "spiritual genius", "fresh vitality, uniqueness and the grace which make its rites and practices operative, not to speak of the paradisal vision which constitutes the origin of its sacred art or of the sapience which lies at the heart of its message". This wisdom, continues Nasr, accounts for the "Ultimate Reality", which is both "beyond everything and at the very heart and center of man's soul", that is to say in his "spirit". The quest for wisdom or knowledge, through "spiritual practice" and the "cultivation of virtues", can lead to "salvation in the highest sense of this term, which means total deliverance from the bonds of all limitations".

Nasr argues that spirituality requires a constant practice and a rigorous discipline within the framework of a religion, and he considers the current commercialization of the "pseudo-spiritual" to be indicative of people wanting the spiritual result without the effort.

Daoud Riffi emphasizes that Sufism is the spiritual path followed by Seyyed Hossein Nasr in a universalist framework which attests to the principial unity of all major religions. Nasr's Sufism relates to the intellect in its medieval sense, that is, the spiritual heart: "True knowledge is therefore a matter of the heart, not of the mind, and the fruit of an interior asceticism."

Exoterism and esoterism
Nasr says that every integral religion "possesses at once an external or exoteric dimension" and "an inner or esoteric dimension". The first is "concerned with the external and formal aspect of human life" with a view to the posthumous salvation of those "who follow the precepts" of their religion and who "have faith in its truths". The second concerns "the formless and the essential" with a view to the realization of "the Supreme Essence, here and now".

These two dimensions unfold in "a hierarchy of levels from the most outward to the most inward which is the Supreme Center". Nasr thus distinguishes three modes of "approaching ultimate Reality": "the ways of work, love and knowledge", which correspond to as many predispositions of human nature. The most interiorizing paths integrate those which are less so, but the latter, not necessarily possessing the capacity "to understand what is beyond them", sometimes become the causes of "tensions" within the same religion. Nasr adds that "all human beings can be saved if only they follow religion according to their own nature and vocation". And he warns "on the social level, on the level of human action, the barriers and conditions established by the exoteric dimension of the religion should not be transgressed", including by those who "follow the path of esoterism, the inward or mystical path".

Since there are "questions that exoterism cannot answer," it is important "for religion to keep alive the reality and the significance of esoterism for people who have the capability and need to understand the inner or esoteric dimension of the tradition". This is what Islam, for example, continues to accomplish today with its inner dimension, Sufism, which remains a living tradition. On the other hand,

"what happened in Christianity, which is a great tragedy, I believe, for both Christianity and Western civilization, and in fact for the rest of the world, is that after the Renaissance, gradually a wall was created, and Western Christianity's inner dimension became more or less inaccessible and to a large extent eclipsed. It is not accidental that during the last two or three hundred years, Christianity has not produced figures such as a Meister Eckhart, Tauler, or Saint Bernard of Clairvaux, and we could go down the list of hundreds of earlier great saints and mystics. [...] today so many people of Christian background look to Buddhism, Islam, and Hinduism for the inner dimension of religion. (interview)"

The essential unity of religions
In a commentary on a work by Nasr, Adnan Aslan reports that for Nasr, the various religions are "forms of the eternal truth which has been revealed by God to humankind through various agencies". It is this common truth which constitutes "the transcendent unity of religions", he says, referring to the expression proposed by Frithjof Schuon.

"It is only on the level of the Supreme Essence [...], standing above all the cosmic sectors from the angelic to the physical within which a particular religion is operative, that the ultimate unity of religions is to be sought". This unity, for Nasr, is "not to be found at the level of external forms; [...] religions do not simply say the same thing despite the remarkable unanimity of principles and doctrines and the profound similarity of applications of these principles". At the heart of every religion lies "what Schuon calls the religio perennis", that is to say, "a doctrine concerning the nature of reality and a method for being able to attain what is Real". Doctrine and method vary from one religion to another but their essence and goal are universal.

As a result, no religion is in itself "better" than another, concludes Nasr, since "all authentic religions come from the same Origin", but in practical terms it is nevertheless necessary "to distinguish the possibilities" that remain valid in the current state of "degradation" of each of the religions. For Nasr, given the celestial origin of all religions, it is appropriate to respect their slightest particularities and to treat them "with reverence, as every manifestation of the sacred should be".

Interreligious dialogue
According to Jane I. Smith, Nasr is "one of the most visible partners" of Islamic-Christian dialogue thanks to "his training in Christian theology and philosophy, combined with his remarkable knowledge of all Islamic sciences".

Nasr points out that ordinary believers consider their religion to be the religion. Injunctions such as: "I am the way, the truth, the life" (Jesus) or "No one sees God unless he has seen me" (Mohammed), necessarily lead, for these same believers, to the certainty of the pre-eminence of their own religion, a conviction that could lead to the refusal to consider other religions as valid. This refusal, for Nasr, can be considered as legitimate since it stems from revelation, therefore from God; God wants to "save souls", he does not ask the believer to deal with "comparative religion" nor to accept the validity of other revelations. In a traditional world, such exclusivism presented no hindrance, but in today's world, the mixing of populations calls many believers to question the value of the religions they encounter daily.

Religion as it is seen in the world, says Nasr, "comes from the wedding between a Divine Norm and a human collectivity destined providentially to receive the imprint of that Norm." Thus, "racial, ethnic and cultural differences" constitute "one of the causes for multiplicity" of religions, "but religion itself cannot be reduced to its terrestrial embodiment". For Nasr, there is only one truth and it necessarily manifests itself in "all the different authentic religious universes, otherwise God would not be merciful and just". But it is not, according to Nasr, the exoteric level, that of divergences, which allows access to a true understanding and acceptance of other religions; only esotericism, which transcends the formal dimensions of religions, allows, according to him, uncompromising adherence to the authenticity of all revelations, by recognizing in them a supra-formal unity which resolves these very differences.

Nasr actively participates in the dialogue between Christians and Muslims. In 2008, he was the main Muslim speaker, opposite Benedict XVI, at the first Catholic-Muslim Forum organized by the Vatican. For Nasr, "one of the reasons why it is so difficult to have a deep religious dialogue today" with Christians, is due – besides their conviction "that there is no salvation outside the Church" – to the absence of an "esoteric dimension, interior [...], mystical", which centuries of secularism have stifled. For Islam, which is not "theologically threatened by the presence of other religions in the same way that Christianity is", the influence of secularism occurred much later than in the West, and Sufism, which is its interior dimension, continues to inspire "the most profound doctrines that have been formulated concerning the plurality of religions and the relationship between them".

For Nasr, as Jahanbegloo emphasizes, dialogue is "not only a pursuit of truth, but also a challenge to spiritual responsibility" of each religion to try to "heal the wounds of the present-day secularized world" in which we live.

Tradition
In Knowledge and the Sacred, Nasr defines tradition as follows:

"Tradition as used in its technical sense [...], means truths or principles of a divine origin revealed or unveiled to mankind and, in fact, a whole cosmic sector through various figures envisaged as messengers, prophets, avatāras, the Logos or other transmitting agencies, along with all the ramifications and applications of these principles in different realms including law and social structure, art, symbolism, the sciences, and embracing of course Supreme Knowledge along with the means for its attainment."

For Nasr, the tradition therefore presents two aspects: "one is truths that are of a transcendent order in their origin, that came from the Divine, from God", revealed at the birth of each of the great religions and, on the other hand, the transmission of these truths by these same religions and by the civilizations they have generated; tradition is therefore not limited to religion – this is its heart – but it is deployed in all areas of a culture, hence the names "traditional art, traditional sciences, traditional architecture, traditional music, traditional clothing, etc."

Following René Guénon – to whom he is "indebted for clarifying this fundamental concept" –, Nasr refers to a "Primordial Tradition", which he defines as being the single truth from which emanate all truths, the immutable and timeless archetype from which all traditions originate. According to Nasr, at a time when Heaven and Earth were still "united", the original or archetypal man was directly enlightened, spiritually and intellectually, by the Primordial Tradition.

The value of tradition, for Nasr, is not manifested by a simple nostalgia for the past, it stems from the wisdom that this tradition conveys, instructing the human being on his own nature and that of the world, and calling him to achieve his original perfection. Only the truths conveyed by tradition, continues Nasr, allow us to grasp the full scope of the errors of modern thought and its misdeeds on man and nature.

Ecology
"That the harmony between man and nature has been destroyed is a fact which most people admit. But not everyone realizes that this disequilibrium is due to the destruction of the harmony between man and God."

It was in 1966, during the Rockefeller Foundation Lectures at the University of Chicago, that Seyyed Hossein Nasr, for the first time, made public the importance that he placed on nature and his concern for its degradation. He was one of the first philosophers to turn to this question and he is considered to be the founder of environmentalism in the Muslim world. In several works he deals with the causes of the mutilation of the planet and the restorative remedies.

Causes

Tarik Quadir argues that "the ecological crisis, for Nasr, is only an externalization of an inner malaise [...] due in large part to the various applications of modern [western] science. [...] Following the loss of the vision of the universe proper to medieval Christian worldview, [...] this science ignores or denies the existence of any reality other than that of the material aspect of nature". Indeed, as Nasr explains, "the Renaissance and its aftermath […] witnessed the rise of a secular humanism and the absolutization of earthly man with immeasurable consequences for both the world of nature and traditional civilizations conquered by this new type of man, who gives free rein to his Promethean ambition to dominate nature and its forces in order to gain wealth or to conquer others civilizations, or both. [...] Nature, more than a lifeless mass, has thus become a machine to be dominated and manipulated by a purely earthly man". Thus, it is "to modernism and its false presumptions about the nature of man and the world", that Nasr attributes "the destruction of the natural environment", in addition to "the disintegration of the social fabric", and he deplores that all States, "from monarchies to communist governments, to revolutionary regimes, […] all want to copy avidly Western science and technology, without thought of their cultural, social and environmental consequences".

Nasr believes that another cause of ecological problems is found in scientism, that is, the conviction that "modern science provides if not the only, at least the most reliable means to true knowledge" and that it leads thereby "to human progress", as imagined by those who evaluate a human society solely in terms of its economic growth. Nasr corroborates the observation that the development of the current economic system rests largely on human passions, which it feeds in its turn, thus generating a continuous blossoming of new needs which, in reality, are only desires. Finally, "if modern man destroys nature with such impunity, it is because he looks upon it as a mere economic resource".

Remedies

Quadir maintains that for Nasr, it is not by technology that environmental problems can be solved in the long term, being themselves the consequence of this technology. According to Nasr, the critique of the extraordinary technological development is certainly necessary, but the real critique must start with the root of the problem, i.e. with oneself, because in a desacralized West, few are aware of what Nasr considers the raison d'être of human life and of nature. This consciousness, for Nasr, is present in the wisdom of the various religious traditions, "as well as in their cosmologies and sacred sciences". And it alone makes it possible to rediscover "the sense of the sacred", in particular with regard to nature,because deprived of this sense, the human being remains immersed in the ephemeral, abandoning himself to his own lower nature, with an illusory feeling of freedom.

As a consequence, the philosopher Ramin Jahanbegloo argues that Nasr's goal "is to negate the totalitarian claims of modern science and to reopen the way to the religious view of the order of nature, developed over centuries in the cosmologies and sacred sciences of the great traditions". "Once the awareness comes of what really nature is, warns Nasr, that nature is not just an 'it', that it is a living reality and has a sacred content, that it has an inner relation with our own inner being, [...] that we cannot destroy nature without destroying ourselves. [...], then we will begin to respect her" and, consequently, the dominant technology will initiate a reconversion. Realizing then, by this interior transformation, that true happiness is not linked to consumption, the human being will recognize his "real and not imagined needs", the only solution to slow down the uncontrolled appetite which leads to the daily rape of the planet.

Critique of modernism
Nasr says that it was in the Renaissance in the West (14th-16th centuries) that the "modernist" or reductive vision of the human condition and the universe began to take shape, and spread to other continents during the past two centuries. This ideology is characterized by "the rejection of the theocentric view of reality", hence an absolutization of the human to the detriment of the Divine, but of a human denying his "pontifical nature", therefore reduced "to his rational and animal aspects, [wandering] in a desacralized wasteland, oblivious to his origin" and living only at the periphery of his being and of the universe.

Nasr considers that after the Renaissance, faith no longer had the monolithic cohesion of the Middle Ages. The "new man" is no longer defined by "his celestial archetype and his Edenic perfection", nor by his "symbolic and contemplative spirit", but by his "individuality, reason, the senses, corporeality [and his] subjectivism". Nasr contends that this marked the beginning of the ever increasing secularization of man and of knowledge, which, step by step, lead the West to skepticism, relativism, individualism, materialism, progressivism, evolutionism, historicism, scientism, agnosticism, atheism and, ultimately, what he considers the present chaos.

According to Nasr, given that the wisdom conveyed by the various traditional civilizations finds its origin in a divine revelation, these civilizations have always transmitted a fair representation of man and his purpose. Thus, as Joseph E. B. Lumbard notes, for Nasr, "only tradition can provide the weapon necessary to carry out the vital battle for the preservation of the things of the spirit in a world which would completely devour man as a spiritual being if it could". According to Nasr:

"To defend the traditional point of view is not to negate the reality of all kinds of evil in the premodern world ranging from wars to philosophical skepticism among the Greeks in the dying moments of that civilization. The major difference is that in traditional civilizations while there was evil, the sacred was ubiquitous and people lived in the world of faith. Today evil continues in many more insidious ways while the very meaning of life which is the quest and discovery of the sacred is taken away."

The theory of evolution
For Nasr, the results of modern scientific investigation of nature are defined by the "oblivion of intellect" and, thus, are "severed from Divinity and highly compartmentalized". He maintains that the scientific explanations for the origins of the natural world are "purely physical" and "aimed at reducing man to matter while excluding divinity and teleology from nature". On this basis, Nasr rejects the theory of evolution, claiming that it is "an ideology, it is not ordinary science," that it is "more a pseudo-religion than a scientific theory," that it "requires more faith than is claimed by any religion for its founder or even for God," and that evolution is both metaphysically and logically impossible. The sociologist Farzin Vahdat sees this as part of Nasr's rejection of secular reason and secular science, and more broadly of the modern world, and Salman Hameed in an editorial for Science identified Nasr as one of a few Islamic creationists active in Western academic institutions.

Marietta Stepaniants observes that, for Nasr, "the absurdity of that theory" is that it offers "horizontal and material causes in a unidimensional world, to explain effects whose causes belong to other levels of reality". As an alternative, Nasr defends his vision of an Islamic philosophy of science that accepts "limited biological changes" occurring throughout time, but rejects the idea that solely natural mechanisms account for what he calls "creativity". He contends that evolutionary biology is a "materialist philosophy" rather than a "real science with a true empirical foundation" and contrasts a Darwinian vision of life with his God-centered perspective of nature based in the traditional Islamic understanding of life and creation. Nasr contends that evolutionism is one of the cornerstones of the contemporary worldview and has contributed directly to the modern world's degradation of the spiritual significance and sacredness of God's creation, as stated in "sacred scriptures" such as the Quran.

Philosophy
Commenting on an article that Muhammad Suheyl Umar dedicated to him, Nasr speaks of his own "philosophical position":

"I am a follower of that philosophia perennis and also universalis, that eternal sophia, which has always been and will always be and in whose perspective there is but one Reality which can say 'I' [...] I have tried to become transparent before the ray of Truth that shines whenever and wherever the veil before it is lifted or rent asunder. Once that process is achieved, the understanding, 'observation' and explication of the manner in which that light shines upon problems of contemporary man constitute for me philosophical creativity in the deepest sense of the term. Otherwise, philosophy becomes sheer mental acrobatics and reason cut off from both the intellect and revelation, nothing but a luciferian instrument leading to dispersion and ultimately dissolution."

For Nasr, the true "love of wisdom" (philosophia) was shared by all civilizations until the emergence, in the West, of a thought which dissociated itself more and more from the spiritual dimension as a result of the occultation of the sapiential core of religion and the divorce of philosophical intelligence from faith. Apart from the case of certain Greek currents such as sophistry and skepticism, as well as the episode of nominalism towards the end of the Middle Ages, it was really during the Renaissance, continues Nasr, that "the separation of philosophy and of revelation" began, despite the maintenance in certain isolated circles of a true spirituality. With the development of individualism and the emergence of rationalism and skepticism, only the purely human faculties – reason and the senses – "determined knowledge, although faith in God still persisted to a certain extent", but that was not enough to hold back "the progressive desacralization of knowledge which characterizes European intellectual history" from this period on and which "led to the completely profane philosophy of today". However, "the very separation of knowledge from being, which lies at the heart of the crisis of modern man is avoided in the Oriental traditions, which consider legitimate only that form of knowledge that can transform the being of the knower".

Adnan Aslan notes a passage from Nasr in which he endorses Plato's commentary in the Phaedo, which equates philosophy with "the practice of death"; this death, for Nasr, corresponds to the extinction of the "I", a necessary stage for the realization of the "Self" or of the "Truth".

Several works by Nasr support critical analyzes of those he considers to be engines of modern deviation: Descartes, Montaigne, F. Bacon, Voltaire, Hume, Rousseau, Kant, Comte, Darwin, Marx, Freud, Aurobindo, Teilhard de Chardin and others. In addition, his writings abundantly cite those who, for him, convey authentic wisdom: Pythagoras, Socrates, Plato, Plotinus, Augustine, Shankara, Erigena, Avicenna, al-Bīrūnī, Suhrawardī, Ibn Arabī, Rūmī, Thomas Aquinas, Eckhart, Dante, Mullā Sadrā, Guénon, Schuon, Coomaraswamy, Burckhardt, Lings, etc.

Scientism
Patrick Laude submits that Nasr is "the only foremost perennialist writer to have received an intensive and advanced academic training in modern sciences" while Joseph E. B. Lumbard contends that "as a trained scientist", Nasr is well suited to argue about the relationship between religion and science.

Summarizing Nasr's thought, Lucian W. Stone, Jr. writes in The Dictionary of Modern American Philosophers: "According to Nasr, while the traditional sciences – which include biology, cosmology, medicine, philosophy, metaphysics, and so on –, understood the natural phenomena and humanity as vestigia Dei (signs of God), modern science has severed the universe, including humans, from God. The natural world or cosmos has a meaning beyond itself, one of which modern secular science is intentionally ignorant".

Nasr argues that historically Western science is "inextricably linked to Islamic science and before it to the Greco-Alexandrian, Indian, ancient Iranian as well as Mesopotamian and Egyptian sciences". Denying this heritage, the Renaissance already – despite some resistance –, but especially the 17th century (Descartes, Galileo, Kepler, Newton), imposed new paradigms in accordance with the ambient anthropocentrism and rationalism, and with the secularization of the cosmos, which have resulted in a "unilateral and monolithic science, [...] bound to a single level of reality [...], a profoundly terrestrial and externalized science".

While not denying the prowess "of a science limited to the physical dimension of reality", Nasr nonetheless argues that "alternative worldviews drawn from traditional doctrines remain constantly aware of the inner nexus which binds physical nature to the realm of Spirit, and the outward face of things to an inner reality which they at once veil and reveal". For the traditional sciences of all civilizations, the universe is formed by a hierarchy of degrees, the most "external" or "lowest" degree being the physical world, the only one that modern science recognizes; this lower degree reflects the higher degrees of the universe "by means of symbols which have remained an ever open gate towards the Invisible".

Nasr speaks of "certain intuitions and discoveries" of contemporary scientists, "which reveal the Divine Origin of the natural world", a deduction that scientism does not want to admit, "the scientific philosophers are much more dogmatic than many scientists in denying any metaphysical significance to the discoveries of science". Scientism presents "modern science not as a particular way of knowing nature, but as a complete and totalitarian philosophy which reduces all reality to the physical domain and does not wish under any condition to accept the possibility of the existence of non-scientistic worldviews". However, Nasr notes, a large number of eminent physicists "have often been the first to deny scientism and even the so-called scientific method [...], seeking to go beyond the scientific reductionism which has played such a great role in the desacralization of nature and of knowledge itself".

According to Lumbard, Nasr considers that:

"Science in and of itself is neutral, and the information that scientific discovery provides is true on its own plane, but science falls into error when it crosses from the realm of scientific investigation into that of scientistic ideology, generalizing and absolutizing a particular vision of the physical domain of the universe that science is able to study and then judging the other disciplines in accord with that narrow vision. [...] Nasr calls for a reintegration of modern science into metaphysics and the traditional cosmological sciences in which knowledge of the level of reality that each discipline is equipped to analyze is perceived through the light of higher forms of knowledge, at the apex of which stands the knowledge of the One before which all is reduced to nothingness."

Art
In his reflections on art, Seyyed Hossein Nasr bases himself on "the traditional perspective which is by nature meta-historic and perennial". For him, all art "must convey the truth and beauty" and "a meaning that is ultimately universal" because it is independent of "the ego of the individual artist". He cites as examples the traditional art, "whether it be Persian and Arabic in the Islamic world, Japanese and Chinese in the Far East, Hindu and Buddhist in the Indian world, medieval Christian in the West", as well as the arts of the "primal people of the Americas, Australia and Africa, who in a sense, belong to one family". "That art is the reflection of a Platonic paradigm, idea, or archetype, in the Platonic sense, in the world of physical forms."

Thus, in traditional art, specifies Nasr, the artist "is an instrument for the expression of certain symbols, of certain ideas, [...] which are beyond the individual and are executed artistically through traditional techniques" because they belong to the "spiritual world"; "this is where the great difference between traditional and modern art comes from". An art is considered traditional "not because of its subject matter but because of its conformity to cosmic laws of forms, to the laws of symbolism, to the formal genius of the particular spiritual universe in which it has been created, its hieratic style, its conformity to the nature of the material used, and, finally, its conformity to the truth" as expressed by the religious milieu from which it comes.

As for sacred art, "which lies at the heart of traditional art [, it] has a sacramental function and is, like religion itself, at once truth and presence"; it "involves the ritual and cultic practices and practical and operative aspects of the paths of spiritual realization". In a traditional society, says Nasr, one does not distinguish between sacred art and religious art but "in the post-medieval West and also outside of the Western world since the 19th century, in fact wherever you already have had the decadence of the traditional arts", religious art is characterized only by its subject, at the expense of "its means of execution and its [supra-individual] symbolism" which "belong to the suprahuman realm". Today "much of what is called religious art is no longer traditional but individualistic and psychological."

For Nasr, the degeneration of Western art since the Renaissance is the consequence of a "view of man as a purely secular and earthly being". From symbolic as it was, art became more and more naturalistic, as can be seen, for example, by comparing the sculptures of Chartres Cathedral to those of Michelangelo, or paintings of the Virgin by Raphael to those of the Middle Ages. But, tired of indefinitely reproducing beings and objects deprived of life, naturalism faded in the second half of the 19th century in front of "this new very ingenious wave of impressionist art which tries to capture some of the qualities of nature […] using light and colors [...], without simply emulating the external forms of nature". This movement, however, was only a "transient phase, and soon the whole world of form broke down from below, [...] starting with Picasso and continuing to our own day". The "cracks in the confines of the solidified mindset created by centuries of humanism, rationalism and empiricism" have opened access to the most "inferior" influences.

According to Nasr, most modern artists "become completely enmeshed in their own egos [...], leading lives which are in many cases not morally disciplined, whereas the traditional perspective", on the contrary, "seeks to free us through spiritual discipline [...] destroying the stranglehold that the lower ego has upon our immortal soul". The traditional artist "does not try to express his own feelings and ideas", as the modern artist does; "Art for art's sake" is not his credo, nor is "innovation, originality and creativity" because, unlike the modern artist, he knows that art has as its goal "the attainment of inner perfection and [...] human need[s] in the deepest sense [...], which are spiritual", intimately linked to "beauty and the truth." "All beauty", writes Nasr, "is a reflection of Divine Beauty and can lead to the Source of that reflection"; but the contemporary rubs shoulders with "ugliness, unaware that the need for beauty is as profound in the human being as the [...] air that we breathe".

For Nasr, there are artists in the present day, rooted in a true spirituality and who express it or attempt to express it in their art, with the humility demanded by "light of the truth and the millennial heritage of traditional art, most of which was produced […] by anonymous artists who humbled themselves before the reality of the Spirit and through their transparency were able to reflect the light of the spiritual world in their works".
