[2] He graduated in 1963 from the Hebrew University of Jerusalem with a Magister Juris, summa cum laude.

After completing his PhD, Raz returned to Israel to teach at the Hebrew University as a lecturer in the faculty of law and department of philosophy.

The Oxford Law Faculty called him "one of the last remaining giants of jurisprudence and philosophy".

[4][5] Raz's first book, The Concept of a Legal System, was based on his doctoral thesis.

In defending his conception of perfectionist liberalism, Raz argues that political institutions are justified by virtue of their contribution to persons' well-being.

Rather, in David McCabe's words, "successful pursuit of objectively valuable goals" produces well-being according to Raz.

[7] Raz's argument for perfectionist liberalism follows from this view of well-being combined with two other premises.

Thus, a person must be autonomous to achieve the goals set by the social forms in a liberal society.

His most recent work deals less with legal theory and more with political philosophy and practical reasoning.
