Every one should be his own physician. We ought to assist, and not to force nature. Eat with moderation...Nothing is good for the body but what we can digest. What medicine can procure digestion? Exercise. What will recruit strength? Sleep.
A state is an association of similar persons whose aim is the best life possible. What is best is happiness, and to be happy is an active exercise of virtue and a complete employment of it.
I talk democracy to these men and women. I tell them that they have the vote, and that theirs is the kingdom and the power and the glory. I say to them You are supreme: exercise your power. They say, That's right: tell us what to do; and I tell them. I say Exercise our vote intelligently by voting for me. And they do. That's democracy; and a splendid thing it is too for putting the right men in the right place.
Societies will, of course, wish to exercise prudence in deciding which technologies that is, which applications of science are to be pursued and which not. But without funding basic research, without supporting the acquisition of knowledge for its own sake, our options become dangerously limited.
To exercise at or near capacity is the best way I know of reaching a true introspective state. If you do it right, it can open all kinds of inner doors.
One of the reasons for its success is that science has a built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.
It is time for us now as a nation to exercise the same reasonable foresight in dealing with our great natural resources that would be shown by any prudent man in conserving and widely using the property which contains the assurance of well-being for himself and his children.
If I find something and feel as though I can contribute to [it] in a way and feel I'm in it, whatever that means, I'm expressing something that I feel is a way to exercise my talent and help communicate a role as a human being in a movie, I will do that.
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.
I am excessively slothful, and wonderfully industrious-by fits. There are epochs when any kind of mental exercise is torture, and when nothing yields me pleasure but the solitary communion with the 'mountains & the woods'-the 'altars' of Byron. I have thus rambled and dreamed away whole months, and awake, at last, to a sort of mania for composition. Then I scribble all day, and read all night, so long as the disease endures.
Almost every man we meet requires some civility; requires to be humored; - he has some fame, some talent, some whim of religion or philanthropy in his head that is not to be questioned, and which spoils all conversation with him. But a friend is a sane man who exercises not my ingenuity, but me.
