A life without cause is a life without effect.

Life does not cease to be funny when people die any more than it ceases to be serious when people laugh. -George Bernard Shaw.

Life is no brief candle to me. It is a sort of splendid torch which I have got a hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations.

When I was young I observed that nine out of every ten things I did were failures, so I did ten times more work

I want to be all used up when I die.

The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
