Abstract
The author of this book suggests three evaluations which, if they are correct, not only justify its publication but found its significance and make it deserve a wide audience: the neo-Thomist movement is in a critical period—but it is a crisis of growth, not of death; existential phenomenology is of privileged importance to-day both in itself and for Thomists: in itself, because it attempts to integrate the partial truths of other approaches into a higher synthesis, and has in fact succeeded in transcending the empiricist-intellectualist dilemma; for Thomists, because the intrinsic value of its synthesis is weakened, not to say vitiated, by the lack of an adequate metaphysical foundation; that therefore both phenomenologists and Thomists have much to gain from a genuine dialogue with each other.
