All food must be capable of being digested, and that what produces digestion is warmth; that is why everything that has soul in it possesses warmth.
AristotleAnything that we have to learn to do we learn by the actual doing of it; People become builders by building and instrumentalists by playing instruments. Similarily, we become just by performing just acts, temperate by performing temperate ones, brave by performing brave ones.
