Abstract

Undoubtedly, American Thomists owe a major share of their confident historical outlook to the writings of Professor Gilson whose latest work is formally concerned with the relative merits of Thomism and other important systems. This is not a new preoccupation with him, since a whole series of earlier books testify to his abiding interest in this problem. But he has now made a fresh exploration of the entire territory in the light of his revised view of the mind of St. Thomas. During the war years, Gilson prepared a new edition of his pioneer study, Le Thomisme, in which the existential character of Thomistic wisdom is placed in high relief. St. Thomas regards God as the supreme and self-subsistent act of existing and the creative source of finite beings, whose highest act is also that of existing. This has a definite effect upon Thomistic metaphysics, since it involves a conception of being as something more than essence or nature. Both essence and existence are constitutive principles of being, and hence the science of being must be directed as well to the existential act.
