Whatever we learn to do, we learn by actually doing it; men come to be builders, for instance, by building, and harp players by playing the harp. In the same way, by doing just acts we come to be just; by doing self-controlled acts, we come to be self-controlled ; and by doing brave acts, we become brave.
AristotleA man who examines each subject from a philosophical standpoint cannot neglect them: he has to omit nothing, and state the truth about each topic.
Aristotle
