We also say that this Judeo-Catholic tradition contains both natural and supernatural truths. We call natural truths those truths which can be arrived at by the rational nature of man by the proper use of his reason. These truths have been expounded in detail by Claude Tresmontant in a series of valuable works and are the existence of a transcendent, personal, intelligent and free God, who has created the world, not out of its substance but out of nothing, and the existence of a strictly spiritual soul, created at the moment of the animation of the human composite and which, at death, separates from the body to render an account to God for its earthly actions. Strictly speaking, these truths are part of the metaphysical heritage of humanity. We argue, then, that the Judeo-Catholic oral tradition contains a metaphysics, i.e. the natural metaphysics of human intelligence.
