Virtue

Aristotle's and Kant's theories of Virtue differ in two main respects. First, since they are informed by different Principles, their contents correspondingly differ. The second respect is structural. For Aristotle, Virtue is a species of acquired habit, which means that a Virtue can become an automatic character trait via the repetition of relevant behavior. For Kant, though, Virtue can never become permanently acquired, because adherence to Principle is constantly being newly challenged. While the Evolvemental Phronetic Principle differs in content from Kant's, because it evaluates the performance of Action, it agrees with him that adherence to it is always an ongoing challenge. Furthermore, to whatever extent Aristotle means 'habit' to be a conditioned tendency to respond to a situation in a certain way, what qualifies for him as 'Virtuous' behavior has no Evolvemental Value. On the other hand, the process of character-building does have Evolvemental Value, because the Individual's deliberate shaping of motion involved in the process appropriately coordinates Exposition and Propriation.
