A lie is of itself mean and something to be avoided, while the truth is good and praiseworthy. A human being is an individual substance of a rational nature. The human individual is composed of a body and soul. As bodily substance, man is a being subject to the same general laws explanations we have for other bodies. Since he is involved in intellection and volition, this raises his being beyond the philosophy of physical beings.
Man is composed of both body and soul.
Neither the soul nor body is complete. They give themselves to each other, and form one unit. Animals perceive issues such as friendliness and hostility by natural instinct, while man compares things. Although man desires happiness, it does not mean that he is not free concerning his choices. These choices of will are thorough intellectual judgments evaluating the objects.
