"What I like about experience is that it is such an honest thing. You may take any number of wrong turnings; but keep your eyes open and you will not be allowed to go very far before the warning signs appear. You may have deceived yourself, but experience is not trying to deceive you. The universe rings true wherever you fairly test it."

He who gives himself to a lover because he is a good man, and in the hope that he will be improved by his company, shows himself to be virtuous, even though the object of his affection turn out to be a villain, and to have no virtue; and if he is deceived he has committed a noble error. For he has proved that for his part he will do anything for anybody with a view to virtue and improvement, than which there can be nothing nobler.
