Love

Love encompasses a range of strong and positive emotional and mental states, from the most sublime virtue or good habit, the deepest interpersonal affection, to the simplest pleasure. An example of this range of meanings is that the love of a mother differs from the love of a spouse, which differs from the love for food. Most commonly, love refers to a feeling of strong attraction and emotional attachment.

Love is considered to be both positive and negative, with its virtue representing human kindness, compassion, and affection—"the unselfish, loyal, and benevolent concern for the good of another"—and its vice representing a human moral flaw akin to vanity, selfishness, amour-propre, and egotism. It may also describe compassionate and affectionate actions towards other humans, oneself, or animals. In its various forms, love acts as a major facilitator of interpersonal relationships and, owing to its central psychological importance, is one of the most common themes in the creative arts. Love has been postulated to be a function that keeps human beings together against menaces and to facilitate the continuation of the species.

Ancient Greek philosophers identified six forms of love: familial love (storge), friendly love or platonic love (philia), romantic love (eros), self-love (philautia), guest love (xenia), and divine or unconditional love (agape). Modern authors have distinguished further varieties of love: fatuous love, unrequited love, empty love, companionate love, consummate love, infatuated love, amour de soi, and courtly love. Numerous cultures have also distinguished Ren, Yuanfen, Mamihlapinatapai, Cafuné, Kama, Bhakti, Mettā, Ishq, Chesed, Amore, charity, Saudade (and other variants or symbioses of these states), as culturally unique words, definitions, or expressions of love in regard to specified "moments" currently lacking in the English language.

The color wheel theory of love defines three primary, three secondary, and nine tertiary love styles, describing them in terms of the traditional color wheel. The triangular theory of love suggests intimacy, passion, and commitment are core components of love. Love has additional religious or spiritual meaning. This diversity of uses and meanings, combined with the complexity of the feelings involved, makes love unusually difficult to consistently define, compared to other emotional states.

Definitions
The word "love" can have a variety of related but distinct meanings in different contexts. Many other languages use multiple words to express some of the different concepts that in English are denoted as "love"; one example is the plurality of Greek concepts for "love". Cultural differences in conceptualizing love make it difficult to establish a universal definition.

Although the nature or essence of love is a subject of frequent debate, different aspects of the word can be clarified by determining what is not love (antonyms of "love"). Love, as a general expression of positive sentiment (a stronger form of like), is commonly contrasted with hate (or neutral apathy). As a less sexual and more emotionally intimate form of romantic attachment, love is commonly contrasted with lust. As an interpersonal relationship with romantic overtones, love is sometimes contrasted with friendship, although the word love is often applied to close friendships or platonic love. Further possible ambiguities come with usages like "girlfriend", "boyfriend", and "just good friends".

Abstractly discussed, love usually refers to a feeling one person experiences for another person. Love often involves caring for, or identifying with, a person or thing (cf. vulnerability and care theory of love), including oneself (cf. narcissism). In addition to cross-cultural differences in understanding love, ideas about love have also changed greatly over time. Some historians date modern conceptions of romantic love to courtly Europe during or after the Middle Ages, although the prior existence of romantic attachments is attested by ancient love poetry.

The complex and of love often reduces its discourse to a thought-terminating cliché. Several common proverbs regard love, from Virgil's "Love conquers all" to The Beatles' "All You Need Is Love". St. Thomas Aquinas, following Aristotle, defines love as "to will the good of another." Bertrand Russell describes love as "absolute value," as opposed to relative value. Philosopher Gottfried Leibniz said that love is "to be delighted by the happiness of another." Meher Baba stated that in love there is a "feeling of unity" and an "active appreciation of the intrinsic worth of the object of love." Biologist Jeremy Griffith defines love as "unconditional selflessness". According to Ambrose Bierce, love is a temporary insanity curable by marriage.

Impersonal
People can express love towards things other than humans; this can range from expressing a strong liking of something, such as "I love popcorn" or that something is essential to one's identity, such as "I love being an actor".

People can have a profound dedication and immense appreciation for an object, principle, or objective, thereby experiencing a sense of love towards it. For example, compassionate outreach and volunteer workers' "love" of their cause may sometimes be born not of interpersonal love but impersonal love, altruism, and strong spiritual or political convictions.

People can also "love" material objects, animals, or activities if they invest themselves in bonding or otherwise identifying with those things. If sexual passion is also involved, then this feeling is called paraphilia.

Interpersonal
Interpersonal love refers to love between human beings. It is a much more potent sentiment than liking a person. Unrequited love refers to feelings of love that are not reciprocated. Interpersonal love is most closely associated with interpersonal relationships. Such love might exist between family members, friends, and couples. There are several psychological disorders related to love, such as erotomania.

Throughout history, philosophy and religion have speculated about the phenomenon of love. In the 20th century, the science of psychology has studied the subject. The sciences of anthropology, neuroscience, and biology have also added to the understanding of the concept of love.

Biological basis
Biological models of sex tend to view love as a mammalian drive, much like hunger or thirst. Helen Fisher, an anthropologist and human behavior researcher, divides the experience of love into three partly overlapping stages: lust, attraction, and attachment. Lust is the feeling of sexual desire; romantic attraction determines what partners find attractive and pursue, ; and attachment involves sharing a home, parental duties, mutual defense, and in humans involves feelings of safety and security. Three distinct neural circuitries, including neurotransmitters, and three behavioral patterns, are associated with these three romantic styles.

Lust is the initial passionate sexual desire that promotes mating, and involves the increased release of hormones such as testosterone and estrogen. These effects rarely last more than a few weeks or months. Attraction is the more individualized and romantic desire for a specific candidate for mating, which develops out of lust as commitment to an individual mate form. Recent studies in neuroscience have indicated that as people fall in love, the brain consistently releases a certain set of chemicals, including the neurotransmitter hormones dopamine, norepinephrine, and serotonin, the same compounds released by amphetamine, stimulating the brain's pleasure center and leading to side effects such as increased heart rate, reduced appetite and sleep, and an intense feeling of excitement. Research indicates that this stage generally lasts from one and a half to three years.

Since the lust and attraction stages are both considered temporary, a third stage is needed to account for long-term relationships. Attachment is the bonding that promotes relationships lasting for many years and even decades. Attachment is generally based on commitments such as marriage and children, or mutual friendship based on things like shared interests. It has been linked to higher levels of the chemicals oxytocin and vasopressin, to a greater degree than what is found in short-term relationships. Enzo Emanuele and coworkers reported the protein molecule known as the nerve growth factor (NGF) has high levels when people first fall in love, but these return to previous levels after one year.

Psychological basis
Psychology depicts love as a cognitive and social phenomenon. Psychologist Robert Sternberg formulated a triangular theory of love in which love has three components: intimacy, commitment, and passion. Intimacy is when two people share confidences and various details of their personal lives, and is usually shown in friendships and romantic love affairs. Commitment is the expectation that the relationship is permanent. Passionate love is shown in infatuation as well as romantic love. All forms of love are viewed as varying combinations of these three components. Non-love does not include any of these components. Liking only includes intimacy. Infatuated love only includes passion. Empty love only includes commitment. Romantic love includes both intimacy and passion. Companionate love includes intimacy and commitment. Fatuous love includes passion and commitment. Consummate love includes all three components.

American psychologist Zick Rubin sought to define love by psychometrics in the 1970s. His work identifies a different set of three factors that constitute love: attachment, caring, and intimacy.

Following developments in electrical theories such as Coulomb's law, which showed that positive and negative charges attract, analogs in human life were envisioned, such as "opposites attract". Research on human mating has generally found this not to be true when it comes to character and personality—people tend to like people similar to themselves. However, in a few unusual and specific domains, such as immune systems, it seems that humans prefer others who are unlike themselves (e.g., with an orthogonal immune system), perhaps because this will lead to a baby that has the best of both worlds.

In recent years, various human bonding theories have been developed, described in terms of attachments, ties, bonds, and affinities. Some Western authorities into two main components, the altruistic and the narcissistic. This view is represented in the works of Scott Peck, whose work in the field of applied psychology explored the definitions of love and evil. Peck maintains that love is a combination of the "concern for the spiritual growth of another" and simple narcissism. In combination, love is an activity, not simply a feeling.

Psychologist Erich Fromm maintained in his book The Art of Loving that love is not merely a feeling but is also actions, and that in fact the "feeling" of love is superficial in comparison to one's commitment to love via a series of loving actions over time. Fromm held that love is ultimately not a feeling at all, but rather is a commitment to, and adherence to, loving actions towards another, oneself, or many others, over a sustained duration. Fromm also described love as a conscious choice that in its early stages might originate as an involuntary feeling, but which then later no longer depends on those feelings, but rather depends only on conscious commitment.

Evolutionary basis


Evolutionary psychology has attempted to provide various reasons for love as a survival tool. Humans are dependent on parental help for a large portion of their lifespans compared to other mammals. Love has therefore been seen as a mechanism to promote parental support of children for this extended time period. Furthermore, researchers as early as Charles Darwin identified unique features of human love compared to other mammals and credited love as a major factor for creating social support systems that enabled the development and expansion of the human species. Another factor may be that sexually transmitted diseases can cause, among other effects, permanently reduced fertility, injury to the fetus, and increase complications during childbirth. This would favor monogamous relationships over polygamy.

Adaptive benefit
Interpersonal love between a man and woman provides an evolutionary adaptive benefit since it facilitates mating and sexual reproduction. However, some organisms can reproduce asexually without mating. Understanding the adaptive benefit of interpersonal love depends on understanding the adaptive benefit of sexual reproduction as opposed to asexual reproduction. Richard Michod reviewed evidence that love, and consequently sexual reproduction, provides two major adaptive advantages. First, sexual reproduction facilitates repair of damages in the DNA that is passed from parent to progeny (during meiosis, a key stage of the sexual process). Second, a gene in either parent may contain a harmful mutation, but in the progeny produced by sexual reproduction, expression of a harmful mutation introduced by one parent is likely to be masked by expression of the unaffected homologous gene from the other parent.

Comparison of scientific models
Biological models of love tend to see it as a drive, similar to hunger or thirst. Psychology sees love as more of a social and cultural phenomenon. Love is influenced by hormones (such as oxytocin), neurotrophins (such as NGF), and pheromones, and how people think and behave in love is influenced by their conceptions of love. The conventional view in biology is that there are two major drives in love: sexual attraction and attachment. Attachment between adults is presumed to work on the same principles that lead an infant to become attached to its mother. The traditional psychological view sees love as being a combination of companionate love and passionate love. Passionate love is intense longing, and is often accompanied by physiological arousal (shortness of breath, rapid heart rate); companionate love is affection and a feeling of intimacy not accompanied by physiological arousal.

Health
Love plays a role in human well-being and health. Engaging in activities associated with love, such as nurturing relationships, has been shown to activate key brain regions responsible for emotion, attention, motivation, and memory. These activities also contribute to the regulation of the autonomic nervous system, leading to stress reduction over time, although the initial stages of love may induce stress. Love's social bonds enhance both physical and mental health, fostering resilience, compassion, and closeness. It boosts immune function and promotes healing, while also encouraging positive motivations and behaviors for individual flourishing and survival. Breakups can evoke a range of emotional states, including distrust, rejection, and anger, leading to trauma and various psychological challenges such as anxiety, social withdrawal, and even love addiction. Individuals may become fixated on past relationships, perpetuating emotional distress akin to addiction. Health benefits grow bigger when married couples are older, this is because the partners play a crucial role in promoting each other's well-being. A loving relationship with God has significant impact on health.

Ancient Greek
Greek distinguishes several different senses in which the word "love" is used. Ancient Greeks identified three main forms of love: friendship and/or platonic desire, sexual and/or romantic desire , and self-emptying or divine love. Modern authors have distinguished further varieties of romantic love.


 * Agape (ἀγάπη )
 * Agape, often a Christian term, denotes a form of love that stands apart from the conventional understanding of affection. Rooted in theological discourse, agape represents a love that is characterized by its spontaneous nature and its independence from the inherent value of its object. Originating from the Greek term for "love", agape has been examined within theological scholarship, particularly in contrast to eros. In the Christian tradition, agape is often attributed to the love of God for humanity, as well as humanity's reciprocal love for God and for one another, often termed as brotherly love. Agape is considered to be unmerited and unmotivated by any inherent worthiness in its recipient. Instead, it is portrayed as an expression of the nature of God, exemplifying divine love that transcends human comprehension.


 * Eros (ἔρως )
 * Eros originally referred to a passionate desire, often synonymous with sexual passion, reflecting an egocentric nature. However, its modern interpretation portrays it as both selfish and responsive to the merits of the beloved, thus contingent on reasons. Plato, in his Symposium, argued that sexual desire, fixated on physical beauty, is inadequate and should evolve into an appreciation of the beauty of the soul, culminating in an appreciation of the form of beauty itself. In Greek mythology, Eros symbolizes the state of being in love, extending beyond mere physical sexuality (referred to as "Venus"). Unrestrained Venus can reduce individuals to mere appetite, but when Eros is present, the focus shifts to the beloved, elevating intimacy beyond physical gratification. Eros is depicted as divine yet potentially dangerous, capable of inspiring both altruism and selfishness.


 * Philia (φιλία )
 * Philia originally describing an affectionate regard or friendly feeling, extended to relationships like friendship, family members, business partners, and one's nation. Similar to eros, philia is often seen as responsive to positive attributes in the beloved. This similarity has led scholars to think whether the primary difference between romantic eros and philia lies solely in the sexual dimension of the former. The distinction between the two becomes more complex with attempts from scholars to diminish the importance of the sexual aspect in eros, contributing to a nuanced understanding of these forms of love. Philia was articulated by Aristotle in his Nicomachean Ethics. Aristotle suggests that philia can be motivated by considerations for either one's own benefit or the benefit of the other. Philia often arises from the utility found in the relationship or from admiration for the character or virtues of the other individual. Aristotle further elucidates that the foundation of philia rests on objective grounds; individuals must share similar dispositions, refrain from holding grudges, and embody qualities such as justice, among others.

Ancient Roman
In Latin, friendship was distinctly termed amicitia, while amor encompassed erotic passion, familial attachment, and, albeit less commonly, the affection between friends. Cicero, in his essay On Friendship reflects on the innate human tendency to both love oneself and seek out another with whom to intertwine minds, nearly blending them into a singular entity. This suggests that while friends remain distinct individuals, they also, in some sense, become intertwined, embodying a shared essence.

Lucretius perceives love as a disruptive and irrational force, leading to madness and despair. To him, it is an affliction distorting reality, a primal urge rooted in the biological need for species to propagate. He emphasizes love's futility and self-destructive nature. In contrast, Ovid acknowledges the pleasure of love alongside its risks and complexities. He views love as a game of manipulation and deception, marked by a blend of hedonism and cynicism. Ovid recognizes the transient nature of passion and the inevitable disappointment in romantic relationships.

Chinese


Ren (仁), a concept in Confucianism philosophy, embodying the essence of humanity and virtue. It is regarded as the sum of all virtues within a person, encompassing traits such as selflessness and self-cultivation. Ren emphasizes the cultivation of harmonious relationships within society, starting from the family unit and extending outward. Within Confucianism, these relationships are delineated by five main categories: father-son, older brother-younger brother, husband-wife, older friend-younger friend, and lord-servant. In Confucianism, one displays benevolent love by performing actions such as filial piety from children, kindness from parents, loyalty to the king and so forth.

Central to the concept of Ren is the notion of reciprocity and empathetic understanding. It is often interpreted as akin to love (愛, ài), but sometimes it also considered a stage between ài and ling, characterized by the sincere and open-hearted expression of human feelings. Through genuine love for others, individuals cultivate Ren and foster deeper connections that bridge the gap between the human and the divine. Ren's significance lies in its ability to foster genuine human connection and empathy, laying the foundation for harmonious relationships within society.

Mozi, a Chinese philosopher, articulated a philosophy centered on the principle of universal love. At the core of his teachings lay the belief that genuine harmony and societal well-being could only be achieved through love for others, transcending narrow self-interest. Mozi contended that universal love was not merely an abstract concept but a practical imperative, requiring individuals to actively promote the welfare of all members of society through their actions.

In Mozi's philosophical framework, universal love was not only a moral obligation but also a divine principle originating from Heaven itself. He argued that this principle was exemplified through the actions of sage-kings from ancient times, who demonstrated how love could manifest in tangible ways within human interactions. Mozi's advocacy for universal love extended beyond interpersonal relationships; he believed it should guide the selection of rulers and the structuring of society, emphasizing reciprocity and egalitarianism as foundational principles for a harmonious social order.

In Taoism, the concept of 慈 (ci) embodies compassion or love, with connotations of tender nurturing akin to a mother's care. It emphasizes the idea that creatures can only thrive through raising and nurturing. Ci serves as the wellspring of compassion or love that transcends preconceived notions of individuals, instead fostering compassion for people as they are. Love, as depicted in the Taoist text, Daodejing, is depicted as open and responsive to each person's unique circumstances. Taoism juxtaposes human beings with the vastness of nature, likening the creation of people to the formation of waves in the ocean. Unlike Confucianism, as portrayed in the Taoist text Zhuangzi, Taoist responses to the loss of a beloved may involve either mourning their passing or embracing the loss and finding joy in new creations. Daoist love seeks connections that surpass distinctions and superficial reflections.

Japanese
The Japanese language uses three words to convey the English equivalent of love — ai (愛), koi (恋 or 孤悲) and ren'ai (恋愛). The term ai carries a multiple meanings, encompassing feelings of feelings from superior to inferiors, compassion and empathy towards others and selfless love, originally referred to beauty and was often used in a religious context. Initially synonymous with koi, representing romantic love between a man and a woman, emphasizing its physical expression, ai underwent a transformation during the early Meiji era. It evolved into a euphemistic term for renbo (恋慕) or love attachment, signifying a shift towards a more egalitarian treatment and consideration of others as equals. Prior to Western influence, the term koi generally represented romantic love. describes a longing for a member of the opposite sex and is typically interpreted as selfish and wanting. The term's origins come from the concept of lonely solitude as a result of separation from a loved one. Though modern usage of focuses on sexual love and infatuation, the Manyō used the term to cover a wider range of situations, including tenderness, benevolence, and material desire. The fusion of ai and koi gave rise to the modern term ren'ai; its usage more closely resembles that of in the form of romantic love.

The concept amae (甘え), the dependency and emotional bonds between an infant and its mother—a bond that lays the foundation for the archetypal concept of love. Japanese culture traditionally distinguishes between marriage and love, valuing practical considerations and complementarity within family units.

Indian
In ancient India, there was a understanding of erotics and the art of love. References in the Rigveda suggest the presence of romantic narratives in ancient Indo-Aryan society, evident in dialogues between deities like Yama and Yami, and Pururavas and Urvashi. The Sanskrit language, offered various terms to convey the concept of love, such as kama, sneha, priya, vatsalya, bhakti, priti and prema.

In Indian literature, there are seven stages of love. The first is preska, characterized by the desire to see something pleasant. Next is abhilasa, involving constant thoughts about the beloved. Then comes raga, signifying the mental inclination to be united with the beloved. Following that is shena, which involves favorable activities directed towards the beloved. Prema is the stage where one cannot live without the beloved. Then there is rati, which involves living together with the beloved. Finally, srngara represents the playful interaction with the beloved.

Kama initially representing desire and longing. Later, Vātsyāyana, the author of the Kama Sutra, explored the concept of kama, defining it as the enjoyment of sensory pleasures with conscious awareness. However, there were also teachings cautioning against becoming overly attached to desire, advocating for the pursuit of genuine happiness through transcending desires. The Atharvaveda, presents kama as the tender affection between partners.

Nevertheless, kama is also often associated with insatiable sexual desire intertwined with intense emotions like anger and greed, portraying it as potentially harmful. Over time, kama took on anthropomorphic qualities, evolving into the figure of the Indian Cupid.

Sneha, considered the emotional facet of love, stands in contrast to the intense passion of kama with its calm demeanor. Characterized by moisture and viscosity, the term originally denoted oiliness. It is often compounded with words for family members, reflecting attachment to individuals like mothers, fathers, and sons. Those experiencing sneha tend to exhibit great concern for one another. While traditionally attributed to sensing, the Harshacharita presents a spontaneous perspective, suggesting it lacks a definitive cause. Due to its emotional nature, sneha is transient, emerging without reason and disappearing likewise.

Preman represents a heightened stage in the development of love, characterized by the unbearable feeling of separation from the beloved. Etymologically, it denotes the sense of endearment akin to one's own. Priti, similar to preman, denotes fondness for anything delightful and familiar. It encompasses a general liking for arts, sports, and objects, while also encompassing a human instinct. Priti is built on foundations of trust and fidelity. Friendly relations (priti) may persist between individuals but are not necessarily bound by affection (sneha).

Vatsalya originally signifies the tender affection exhibited by a cow towards her calf, extending to denote the love nurtured by elders or superiors towards the younger or inferior. This love is exemplified in the affection of parents towards their children, a husband's care for his wife, or a ruler's concern for their subjects. Conversely, bhakti denotes the love expressed by the younger towards the seniors, exemplified in a child's devotion to their parents.

Persian
Interpretations of Rumi's poetry and Sufi cosmology by scholars emphasize a divine-centric perspective, focusing on the transcendent nature of love. These interpretations emphasize Rumi's rejection of mortal attachments in favor of a love for the ultimate beloved, seen as embodying absolute beauty and grandeur. Scholars like William Chittick assert that all love stems from the divine, with God being both lover and beloved. Leonard Lewisohn characterizes Rumi's poetry as part of a mystical tradition that celebrates love as pathways to union with the divine, highlighting a transcendent experience.

In Persian mysticism, the concept of creation stems from love, viewed as the fundamental essence from which all beings originate and to which they ultimately return. This notion, influenced by neoplatonism, portrays love as both earthly and transcendent, embodying a universal striving for reunion with the divine. Scholars such as Abdolhossein Zarrinkoob trace this philosophical stance, highlighting its fusion with ancient Persian religious beliefs in figures like Ibn Arabi. According to Islamicists like William Chittick and Leonard Lewisohn, all forms of love find their origin in divine love, with creation serving as a reflection of God's beauty and love. This perspective is evident in the poetry of Hafez and others, where the concept of tajalli, or divine self-manifestation, underscores the profound spiritual significance of love as it pertains to both human relationships and devotion to God.

Judaism
In Hebrew, אהבה (ahavah) signifies the love of Israelites for God and each other. However, the concept hesed offers a deeper understanding of love within Jewish thought and life. It goes beyond mere passion, embodying a character trait that is actively expressed through generosity and grace. Hesed has a dual nature: when attributed to God, it denotes grace or favor, while when practiced by humans, it reflects piety and devotion.

Hasidim, demonstrate their commitment and love for God through acts of hesed. The Torah serves as a guide, outlining how Israelites should express their love for God, show reverence for nature, and demonstrate compassion toward fellow human beings. The commandment "Love thy neighbor as thyself" from the Torah's, gives emphasis on ethical obligations and impartiality in judgment. It highlights the importance of treating all individuals equally before the law, rejecting favoritism and bribery; deuteronomy further emphasizes impartiality in judgment.

As for love between marital partners, this is deemed an essential ingredient to life: "See life with the wife you love" (Ecclesiastes ). Rabbi David Wolpe writes that "love is not only about the feelings of the lover... It is when one person believes in another person and shows it." He further states that "love... is a feeling that expresses itself in action. What we really feel is reflected in what we do." The biblical book Song of Solomon is considered a romantically phrased metaphor of love between God and his people, but in its plain reading it reads like a love song. The 20th-century rabbi Eliyahu Eliezer Dessler is frequently quoted as defining love from the Jewish point of view as "giving without expecting to take".

Christianity
The Christian understanding is that love comes from God, who is himself love. The love of man and woman— in Greek—and the unselfish love of others, are often contrasted as "descending" and "ascending" love, respectively, but are ultimately the same thing.

There are several Greek words for "love" that are regularly referred to in Christian circles. Two other words for love in the Greek language, (sexual love) and  (child-to-parent love), were never used in the New Testament.
 * : In the New Testament, is charitable, selfless, altruistic, and unconditional. It is parental love, seen as creating goodness in the world; it is the way God is seen to love humanity, and it is seen as the kind of love that Christians aspire to have for one another.
 * : Also used in the New Testament, is a human response to something that is found to be delightful. Also known as "brotherly love."

Christians believe that to love God with all your heart, mind, and strength and love your neighbor as yourself are the two most important things in life (the greatest commandment of the Jewish Torah, according to Jesus; cf. Gospel of Mark ). Saint Augustine summarized this when he wrote "Love God, and do as thou wilt."

The Apostle Paul glorified love as the most important virtue of all. Describing love in the famous poetic interpretation in 1 Corinthians, he wrote, "Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, and always perseveres." 

The Apostle John wrote, "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him." (John ) John also wrote, "Dear friends, let us love one another for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love." 

Saint Augustine wrote that one must be able to decipher the difference between love and lust. Lust, according to Saint Augustine, is an overindulgence, but to love and be loved is what he has sought for his entire life. He even says, "I was in love with love." Finally, he does fall in love and is loved back, by God. Saint Augustine says the only one who can love you truly and fully is God, because love with a human only allows for flaws such as "jealousy, suspicion, fear, anger, and contention." According to Saint Augustine, to love God is "to attain the peace which is yours."

Augustine regards the duplex commandment of love in as the heart of Christian faith and the interpretation of the Bible. After the review of Christian doctrine, Augustine treats the problem of love in terms of use and enjoyment until the end of Book I of De Doctrina Christiana (1.22.21–1.40.44).

Christian theologians see God as the source of love, which is mirrored in humans and their own loving relationships. Influential Christian theologian C. S. Lewis wrote a book called The Four Loves. Benedict XVI named his first encyclical God is love. He said that a human being, created in the image of God, who is love, is able to practice love; to give himself to God and others and by receiving and experiencing God's love in contemplation. This life of love, according to him, is the life of the saints such as Teresa of Calcutta and Mary, the mother of Jesus and is the direction Christians take when they believe that God loves them.

Pope Francis asserts that the "Cross (Jesus crucified) is the greatest meaning of the greatest love," and in the crucifixion is found everything, all knowledge and the entirety of God's love. Pope Francis taught that "True love is both loving and letting oneself be loved... what is important in love is not our loving, but allowing ourselves to be loved by God." And so, in the analysis of a Catholic theologian, for Pope Francis, "the key to love... is not our activity. It is the activity of the greatest, and the source, of all the powers in the universe: God's."

In Christianity the practical definition of love is summarized by Thomas Aquinas, who defined love as "to will the good of another," or to desire for another to succeed. This is an explanation of the Christian need to love others, including their enemies. Thomas Aquinas explains that Christian love is motivated by the need to see others succeed in life, to be good people.

Regarding love for enemies, Jesus is quoted in the Gospel of Matthew:

"You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect."

Tertullian wrote regarding love for enemies: "Our individual, extraordinary, and perfect goodness consists in loving our enemies. To love one's friends is common practice, to love one's enemies only among Christians."

Islam
Love encompasses the Islamic view of life as universal brotherhood that applies to all who hold faith. Among the 99 names of God (Allah) is the name Al-Wadud, or "the Loving One," which is found in Surah and. God is also referenced at the beginning of every chapter in the Qur'an as Ar-Rahman and Ar-Rahim, or the "Most Compassionate" and the "Most Merciful", indicating that nobody is more loving, compassionate, and benevolent than God. The Qur'an refers to God as being "full of loving kindness."

The Qur'an exhorts Muslim believers to treat, with or "deep kindness" as stated in Surah. is also used by the Qur'an to describe the love and kindness that children must show to their parents.

, or divine love, is emphasized by Sufism in the Islamic tradition. Practitioners of Sufism believe that love is a projection of the essence of God into the universe. God desires to recognize beauty, and as if one looks at a mirror to see oneself, God "looks" at himself within the dynamics of nature. Since everything is a reflection of God, the school of Sufism practices seeing the beauty inside the apparently ugly. Sufism is often referred to as the religion of love. God in Sufism is referred to in three main terms—Lover, Loved, and Beloved—with the last of these terms often seen in Sufi poetry. A common viewpoint of Sufism is that through love, humankind can return to its inherent purity and grace. The saints of Sufism are infamous for being "drunk" due to their love of God; hence, the constant reference to wine in Sufi poetry and music.

Bahá'í Faith
The Bahá'í concept of the human soul emphasizes its expression through capacities such as knowledge, love, and will. According to Bahá'í teachings, conscious recognition of one's Creator and a reciprocal love relationship with that Creator form the basis of obedience to religious law. This perspective grounds adherence to law within the spiritual dynamics of each individual's journey, portraying obedience as a conscious choice driven by love rather than as mere compliance with external dictates.

Baháʼu'lláh, the founder of the Bahá'í Faith, emphasizes the importance of observing God's commandments out of love, describing them as "the lamps of My loving providence" and urging followers to adhere to them for "the love of My beauty." This framing positions love as the motive force for individuals striving to follow divine laws. In Bahá'í understanding, love is considered the fundamental universal law. ʻAbdu'l-Bahá, Bahá'u'lláh's son and successor, describes love as the "most great law" and the force that binds together the diverse elements of the material world. He further asserts that love is the establisher of true civilization and the source of glory for every race and nation.

From the Bahá'í perspective, God's revelation of laws to humanity is an act of love, and the legitimate reason for their application and adherence lies in their expression of love. This understanding underscores the intimate connection between spiritual principles, individual growth, and the practice of religious law within the Bahá'í Faith.

Buddhism
In Buddhism, is sensuous, sexual love. It is an obstacle on the path to enlightenment, since it is selfish. is compassion and mercy, which reduces the suffering of others. It is complementary to wisdom and is necessary for enlightenment. and are benevolent love. This love is unconditional and requires considerable self-acceptance. This is quite different from ordinary love, which is usually about attachment and sex and which rarely occurs without self-interest. Instead, in Buddhism love refers to detachment and unselfish interest in others' welfare.

The Bodhisattva ideal in Mahayana Buddhism involves the complete renunciation of oneself in order to take on the burden of a suffering world.

Hinduism
In Hinduism, is pleasurable, sexual love, personified by the god Kamadeva. For many Hindu schools, it is the third end in life. Kamadeva is often pictured holding a bow of sugar cane and an arrow of flowers; he may ride upon a great parrot. He is usually accompanied by his consort Rati and his companion Vasanta, lord of the spring season. Stone images of Kamadeva and Rati can be seen on the door of the Chennakeshava Temple, Belur, in Karnataka, India. Maara is another name for.

In contrast to, —or refers to "elevated" love. is compassion and mercy, which impels one to help reduce the suffering of others. is a Sanskrit term meaning "loving devotion to the divine." A person who practices is called a. Hindu writers, theologians, and philosophers have distinguished nine forms of, which can be found in the Bhagavata Purana and works by Tulsidas. The philosophical work Narada Bhakti Sutra, written by an unknown author (presumed to be Narada), distinguishes eleven forms of love.

In certain Vaishnava sects within Hinduism, attaining unadulterated, unconditional, and incessant love for the Godhead is considered the foremost goal of life. Gaudiya Vaishnavas, who worship Krishna as the Supreme Personality of Godhead and the cause of all causes, consider Love for Godhead,, to act in two ways: and  (union and separation)—two opposites.

In the condition of separation, there is an acute yearning for being with the beloved and in the condition of union, there is supreme happiness. Gaudiya Vaishnavas consider that Krishna-prema (love for Godhead) burns away one's material desires, pierces the heart, and washes away everything—one's pride, one's religious rules, and one's shyness. Krishna-prema is considered to make one drown in the ocean of transcendental ecstasy and pleasure. The love of Radha, a cowherd girl, for Krishna is often cited as the supreme example of love for Godhead by Gaudiya Vaishnavas. Radha is considered to be the internal potency of Krishna, and is the supreme lover of Godhead. Her example of love is considered to be beyond the understanding of the material realm, as it surpasses any form of selfish love or lust that is visible in the material world. The reciprocal love between Radha (the supreme lover) and Krishna (God as the Supremely Loved) is the subject of many poetic compositions in India, such as the Gita Govinda of Jayadeva and Hari Bhakti Shuddhodhaya.

In the tradition within Hinduism, it is believed that execution of devotional service to God leads to the development of Love for God, and as love for God increases in the heart, the more one becomes free from material contamination. Being perfectly in love with God or Krishna makes one perfectly free from material contamination, and this is the ultimate way of salvation or liberation. In this tradition, salvation or liberation is considered inferior to love, and just an incidental by-product. Being absorbed in Love for God is considered to be the perfection of life.

Free love
The term "free love" has been used to describe a social movement that rejects marriage, which is seen as a form of social bondage. The free love movement's initial goal was to separate the state from sexual matters such as marriage, birth control, and adultery. It claimed that such issues were the concern of the people involved, and no one else.

Many people in the early 19th century believed that marriage was an important aspect of life to "fulfill earthly human happiness." Middle-class Americans wanted the home to be a place of stability in an uncertain world. This mentality created a vision of strongly defined gender roles, which provoked the advancement of the free love movement as a contrast.

Advocates of free love had two strong beliefs: opposition to the idea of forceful sexual activity in a relationship and advocacy for a woman to use her body in any way that she pleases. These are also beliefs of feminism.

Philosophical views
Philosophically, there four types of love that are distinguished: love as a union; love as robust concern; love as valuing; and love as an emotion. Love as a union suggests that love involves the formation of a union between the two individuals, creating a "we". Roger Scruton and Mark Fisher emphasize the union of concerns, where the distinction between the lover's different interests dissapears and a new shared care and concern emerges. Robert C. Solomon views love as a literal fusion between the two individuals, resulting in a shared identity and mutual definition. Robert Nozick argues that love creates a new "we" through the pooling of well-being and autonomy, as well as the adoption of a joint identity. Critics argue that love as a union undermines individual autonomy and the lovers become unintelligible. However, Nozick and Fisher claim that this loss is a desirable aspect of love. Michael Friedman proposes a federation model, where love creates a new unified entity without erasing individual identities, thus allowing for the concern for the beloved's sake. Love as a robust concern posits that love is primarily defined by caring about the beloved's sake, without creating a "we" or any type of union between the lovers. This perspective emphasizes the willing aspect of love, where one's desire and motivations are shaped by concern for the beloved's well-being. Critics of this view argue that the definition is too passive, in the sense that the conception of the beloved overlooks the interactive nature of love, as well as the emotional responsiveness to the beloved. However, defenders argue that promoting the beloved's well-being requires respecting their autonomy and emotional responses. Furthermore, critics claim that the robust concern focus solely on desires and concerns for the beloved's welfare, making it too strict of a definition. Defenders counter that the desire for the beloved's well being is an essential aspect to love. Monique Wonderly suggests that the concept of attachment can complement the robust concern view, capturing the idea that the beloved is not only important for their own sake but also to the lover.

Love as valuing has two main approaches: love as appraisal of value and love as bestowal of value. J. David Velleman proposes that the former involves acknowledging and responding uniquely to the value of the beloved. Kantian distinctions are drawn between dignity and price, dignity being that the value of something is not comparable, and price being that it is comparable; thus people possess dignity due to their rational nature. Love, on this view, responds to the dignity of persons, but it differs from respect in that it disarms emotional defenses, making one vulnerable to the beloved. However, critics argue that Velleman's account struggles to explain the selectivity and constancy of love, as well as the role of emotions in appraisal. Peter Singer claims that love as a bestowal of value involves bestowing intrisic value upon the beloved. Unlike appraisal, which responds to pre-existing value, bestowal creates value in the beloved. Singer argues that love is non-teleological and cannot be justified, but rather involves attachment and commitment to the beloved. However, critics question how bestowal accounts for the selectivity of love and its discerning nature.

Finally, love as an emotion is divided in two perspectives: love as emotion proper and love as emotion complex. The former sees love as a particular motivational response to an object, similar to other emotions. However, critics argue that defining love solely as an emotion oversimplifies its nature. James Robert Brown suggests that love evaluates the beloved as worthwhile, but this perspective fails to capture the complexity of love compared to other evaluative responses like admiration or respect, according to critics. Love as emotion complex understands love as a complex emotional attitude towards another person, involving historical patterns concerning of one's emotional responsiveness to the beloved. It emphasizes the dynamic nature of love, where ther lover's identity is continually transformed by loving the beloved. Emotional responses are interconnected and tied to the historical narrative of the relationship. Annette Baier and Neera K. Badhwar emphasize emotional interdependence, while Paul Helm suggests that love involves intimate identification, where sharing the values of the beloved is central. Critics argue that these views do not answer how to distinguish loving relationship from other relationships and what constitues the characteristic narrative history of love.
