I am called to man's labour; why then do I make a difficulty if I am going out to do what I was born to do and what I was brought into the world for?

Neither worse then nor better is a thing made by being praised.

If any man can convince me and bring home to me that I do not think or act aright, gladly will I change; for I search after truth, by which man never yet was harmed. But he is harmed who abideth on still in his deception and ignorance.

If any man despises me, that is his problem. My only concern is not doing or saying anything deserving of contempt.

Once you have done a man a service, what more reward would you have? Is it not enough to have obeyed the laws of your own nature, without expecting to be paid for it?

The best revenge is to be unlike him who performed the injury.
