What a man does, that he has. What has he to do with hope or fear? In himself is his might. Let him regard no good as solid but that which is in his nature, and which must grow out of him as long as he exists. The goods of fortune may come and go like summer leaves; let him scatter them on every wind as the momentary signs of his infinite productiveness.
“The more pleasure a universe can yield, other things being equal, the more beneficent and generous is its general nature; the more pains its constitution involves, the darker and more malign its total temper. To deny this would seem impossible, yet it is done daily; for there is nothing people will not maintain when they are slaves to superstition; and candor and a sense of justice are, in such a case, the first things lost.”
“Since the days of Descartes it has been a conception familiar to philosophers that every visible event in nature might be explained by previous visible events, and that all the motions, for instance, of the tongue in speech, or of the hand in painting, might have merely physical causes. If consciousness is thus accessory to life and not essential to it, the race of man might have existed upon the earth and acquired all the arts necessary for its subsistence without possessing a single sensation, idea, or emotion. Natural selection might have secured the survival of those automata which made useful reactions upon their environment. An instinct would have been developed, dangers would have been shunned without being feared, and injuries avenged without being felt.”
