Man belongs wherever he wants to go - and he'll do plenty well when he gets there.

My experiences with science led me to God. They challenge science to prove the existence of God. But must we really light a candle to see the sun?

I have learned to use the word 'impossible' with the greatest caution.

Science does not have a moral dimension. It is like a knife. If you give it to a surgeon or a murderer, each will use it differently.

Basic research is what I am doing when I don't know what I am doing.

It was very successful, but it fell on the wrong planet.

The rocket worked perfectly, except for landing on the wrong planet.

It takes sixty-five thousand errors before you are qualified to make a rocket.

The best computer is a man, and it’s the only one that can be mass-produced by unskilled labor.

Don't tell me that man doesn't belong out there. Man belongs wherever he wants to go - and he'll do plenty well when he gets there.

I have my gun and my bible under my pillow, having to fight physically and spiritually is a foregone conclusion, I will kill whoever comes to kill me, no mercy.

My singing voice isn't like my speaking voice.

Never be a spectator of unfairness or stupidity. Seek out argument and disputation for their own sake; the grave will supply plenty of time for silence.

We must not confuse dissent with disloyalty. We must not walk in fear of one another. We must not be driven by fear into an age of unreason.

Feed the musician, and he's out of tune.

I am a liberal and always have been - just not the wild-eyed character the Republicans made me out to be.

I require something so horrifically alcoholic that it makes livers tremble with fear and run for their lives when its name is uttered.

Focus on what you want, not on what you don't want.
