Abstract
Empirical evidence suggests that human nature tends to be corrupt from the very outset of our moral life. In Sections II and III of the First Piece of Religion, Immanuel Kant approaches this theme of the corruption of human goodness in a more direct way. Although our predisposition is good, he argues that all human beings must have a propensity or original inclination that points us in the opposite direction. In Section II, he argues that, if it exists, then its status must be more than just that of an accidental or optional feature of human experience; this propensity must be inevitable. Section III explains how even people who appear to be good may be concealing an evil heart, if we understand the concept of evil in a philosophically appropriate manner. Human evil arises as a perversion of an originally good predisposition.
