'Over a hundred years ago, the German poet Heine warned the French not to underestimate the power of ideas- philosophical concepts nurtured in the stillness of a professor's study could destroy a civilisation' - Isaiah Berlin, Two Concepts of Liberty , 1958. The nineteen essays collected here show Isaiah Berlin at his most lucid- these short, introductory pieces provide the perfect starting point for the reader new to his work. Their linking theme is the crucial social and political role of ideas, and of their progenitors. The subjects vary widely - from philosophy to education, from Russia to Israel, from Marxism to romanticism - and the appositeness of Heine's warning is exemplified on a broad front. The contents include Berlin's last essay - a retrospective autobiographical survey and the classic statement of his Zionist views. As a whole the book exhibits the full range of his expertise, and demonstrates the enormously engaging individuality, as well as the power, of his own ideas.

Jacob Milgrom, a rabbi and Bible scholar, has devoted the bulk of his career to examining the laws of the Torah. His incisive commentary on Leviticus, which began with Leviticus 1-16, continues in this last volume of three. It provides an authoritative and comprehensive explanation of ethical values concealed in Israel's rituals. Although at first glance Leviticus seems far removed from the modern-day world, Milgrom's thoughtful and provocative comments and notes reveal its enduring relevance to contemporary society. Leviticus 23-27 brings us to the climactic end of the book and its revolutionary innovations, among which are the evolution of the festival calendar with its emphasis on folk traditions, and the jubilee, the priestly answer to the socio-economic problems of their time. With English translations that convey the nuance and power of the original Hebrew, this trilogy will take its place alongside the best of the Anchor Bible Commentaries.

This work is a discussion of one of the major issues in contemporary thinking by two of the world's leading thinkers. From the Stoics to Kant's idea of "perpetual peace", cosmopolitanism has been at the heart of philosophical and political thinking but until now has received little attention from contemporary commentators. Jacques Derrida asks how it is possible to uphold an international hospitality and sense of justice in the face of increasing nationalism and hostility to refugees. Richard Rorty asks whether the ideals of rights enshrined in liberty, equality and fraternity implicit in global cosmopolitanism are sustainable when the very concept of rights is problematic. What have duties and rights to do with hospitality? Should hospitality be grounded on a private or public ethic? Should we look to the city rather than the state for protection of basic freedoms?
