This textbook combines Father Klubertanz' Introduction to the Philosophy of Being and Father Holloway's Natural Theology in a new two-part abridgement, appropriate for single semester courses in general metaphysics and natural theology. The standpoint of both the authors is roughly that of existential Thomism, and the continuity between the work of each within the book is notable. The first part contains the revisions to be found in the second edition of Father Klubertanz' volume.—C. V.
