Career
Kramer was born in Massachusetts and educated at Middleborough High School, Cornell University (B.A. in Philosophy) where he became a member of the Phi Beta Kappa Society, Harvard University (J.D.) and Cambridge University (Ph.D. in Philosophy and LL.D.).

His seventeen books as author and four as editor, as well as his dozens of journal articles, range over many areas of legal, political and moral philosophy. He has received several major research awards including a Guggenheim Foundation Fellowship (2001) and a Leverhulme Trust Major Research Fellowship (2005). He is a subject editor for the Routledge Encyclopedia of Philosophy and is on the editorial board of the Oxford Studies in Political Philosophy, the American Journal of Jurisprudence, Law & Philosophy, Ratio Juris, and Legal Theory. He is also an Advisory Editor for the University of Bologna Law Review (general student-edited law journal).

At the undergraduate level he lectures and supervises in Jurisprudence, and he also lectures on Topics in Legal & Political Philosophy in the postgraduate LL.M. program. At Cambridge, he is a graduate supervisor both for Ph.D. students in the Law Faculty and for M.Phil. and Ph.D. students in the Philosophy Faculty.

He was a visiting professor at Hebrew University of Jerusalem in April 2009, and at Tel Aviv University in March 2012.

In 2014 he was elected a Fellow of the British Academy, the United Kingdom's national academy for the humanities and social sciences.

Inclusive legal positivism
An inclusive legal positivist, Kramer argues in his book Where Law and Morality Meet that moral principles can enter into the law of any jurisdiction. He contends that legal officials can invoke moral principles as laws for resolving disputes, and that they can also invoke them as threshold tests which ordinary laws must satisfy. In opposition to many other theorists, Kramer argues that these functions of moral principles are consistent with all the essential characteristics of any legal system. He is also a leading proponent of the legal positivist argument that law and morality are separable, arguing against the position of natural-law theory, which portrays legal requirements as a species of moral requirements. According to him, even though the existence of a legal system in any sizeable society is essential for the realization of fundamental moral values, law is not inherently moral either in its effects or in its motivational underpinnings.

Moral realism as a moral doctrine
Influenced by the theories of Ronald Dworkin, Kramer is a moral realist who argues that "moral requirements are strongly objective" and that "the objectivity of ethics is itself an ethical matter that rests primarily on ethical considerations." In his book Moral Realism as a Moral Doctrine, he claims that "[m]oral realism - the doctrine that morality is indeed objective - is a moral doctrine." Unlike Dworkin, he believes that, although there is a determinately correct moral answer to most moral questions, there exists genuine moral indeterminacy in relation to some rare moral questions. He also distances himself from Dworkin's defense of value monism.
