There are two distinctive peculiarities by reference to which we characterize the soul (1) local movement and (2) thinking, discriminating, and perceiving. Thinking both speculative and practical is regarded as akin to a form of perceiving; for in the one as well as the other the soul discriminates and is cognizant of something which is.
AristotleWe become just by the practice of just actions, self-controlled by exercising self-control, and courageous by performing acts of courage.
Aristotle
