But the virtues we get by first exercising them, as also happens in the case of the arts as well. For the things we have to learn before we can do them, we learn by doing them, e.g. men become builders by building and lyre players by playing the lyre; so too we become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts.

The statesman who should attempt to direct private people in what manner they ought to employ their capitals would not only load himself with most unnecessary attention but assume an authority which could safely be trusted to no council and senate whatever, and which would nowhere be so dangerous as in the hands of man who have folly and presumption enough to fancy himself fit to exercise it.
I came out for exercise, gentle exercise, and to notice the scenery and to botanise. And no sooner do I get on that accursed machine than off I go hammer and tongs; I never look to right or left, never notice a flower, never see a view - get hot, juicy, red - like a grilled chop. Get me on that machine and I have to go. I go scorching along the road, and cursing aloud at myself for doing it.
