What a piece of work is a man! How noble in reason! How infinite in faculties! In form and moving, how express and admirable! In action how like an angel! In apprehension how like a god! The beauty of the world! The paragon of animals! And yet, to me, what is this quintessence of dust?

I do not see why man should not be just as cruel as nature.

Man must rise above the Earth - to the top of the atmosphere and beyond - for only thus will he fully understand the world in which he lives.

Let every man be respected as an individual and no man idolized.

As human beings, our greatness lies not so much in being able to remake the world - that is the myth of the atomic age - as in being able to remake ourselves.

The world don't need any more songs... As a matter of fact, if nobody wrote any songs from this day on, the world ain't gonna suffer for it... There's enough songs for people to listen to, if they want to listen to songs. For every man, woman and child on earth, they could be sent, probably, each of them, a hundred songs, and never be repeated... Unless someone's gonna come along with a pure heart and has something to say. That's a different story.
