In this long-awaited volume, on which he worked for twenty years, Mr. Wolfson describes the body of doctrine known as the Kalam. Kalam, an Arabic term meaning "speech" and hence "discussion," was applied to early attempts in Islam to adduce philosophic proofs for religious beliefs. It later came to designate a system of religious philosophy which reached its highest point in the eleventh century; the masters of Kalam, known as Mutakallimun, were in many respects the Muslim equivalent of the Christian Church Fathers. Mr. Wolfson studies the Kalam systematically, unfolding its philosophic origins and implications and observing its repercussions in other religions. He scrutinizes the texts of Muslim writers for their treatment of such crucial problems as the attributes of God, the Creation, causality, predestination and free will. In the process he shows how the teachings of the Koran were constantly interwoven with ideas from Greek and Oriental philosophies, Judaism, and Christianity as Islamic thought developed.

As lucidly written and intellectually stimulating as all the author's earlier books, this volume is a fitting capstone to a notable career.

Harry Wolfson spent sixty-six years at Harvard University, as undergraduate, graduate student, teacher, and professor emeritus. From 1925 until his retirement in 1958 he was Nathan Littauer Professor of Hebrew Literature and Philosophy at Harvard. He died in September 1974 at the age of 86.

The Philosophy of the Kalam is the last major work of one of the great scholars of our age. Harry Wolfson was renowned throughout the world for the depth, scope, and wisdom of his monumental volumes on the structure and growth of philosophic systems from Plato to Spinoza. It was not only his extraordinary erudition that commanded respect, his awesome mastery of all the primary sources, Greek, Christian, Judaic, and Muslim; it was also his penetrating insight and his original and groundbreaking interpretations.

Harry Austryn Wolfson was Nathan Littauer Professor of Hebrew Literature and Philosophy, Emeritus, Harvard University.
