Soviet philosophy can no longer be ignored by any serious student of contemporary thought. It is the work of academic philosophers who, on the whole, are neither more nor less competent than their colleagues in the free world. They have, however, inherited a reputation for the dogmatic repetip. on of superannuated doctrines. This reputation, en­ gendered by poor work under political pressure, was justified until about the mid-fifties. However, in the mid-sixties, when declining pressures make for the toleration of a wider scale of qualified opinion, it is no longer that. The present survey of Soviet thought in the mid-sixties, comprising papers by Western specialists in its major domains, gives an up-to-date account of an impressive field of philosophical endeavor which, awakened from dogmap'c slumbers, rapidly gains in interest and encourages hopes of becoming a valuable component in the vast complex of contemporary philosophy. The studies on Soviet logic and atheism have originally appeared in a special issue of Inquiry (Vol. 9,1) devoted to philosophy in Eastern Europe and edited by the present writer on behalf of Professor Arne Naess. The other papers of this volume are reprinted from Studies in Soviet Thought, the only Western philosophical review entirely dedicated to systematic studies in this field.
