“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.”

It is in scientific honesty that I endorse the presentation of alternative theories for the origin of the universe, life and man in the science classroom. It would be an error to overlook the possibility that the universe was planned rather than happening by chance.

There is just one thing I can promise you about the outer-space program – your tax-dollar will go further.

The same forces of nature which enable us to fly to the stars, enable us also to destroy our star.

Crash programs fail because they are based on theory that, with nine women pregnant, you can get a baby in a month.

To simply dismiss the concept of God as being unscientific is to violate the very objectivity of science itself.

Everybody knows what the moon is, everybody knows what this decade is, and everybody can tell a live astronaut who returned from the moon from one who didn’t.

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.

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

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

Looking back, nothing seems so simple than a utopian vision realised.

I find it as difficult to understand a scientist who does not acknowledge the presence of a superior rationality behind the existence of the universe as it is to comprehend a theologian who would deny the advances of science.

I believe in an immortal soul. Science has proved that nothing disintegrates into nothingness. Life and soul, therefore, cannot disintegrate into nothingness, and so are immortal.

The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.

If we were to start today on an organized and well-supported space program I believe a practical passenger rocket can be built and tested within ten years.

I’m convinced that before the year 2000 is over, the first child will have been born on the moon.

I believe that the time has arrived for medical investigation of the problems of manned rocket flight, for it will not be the engineering problems but rather the limits of the human frame that will make the final decision as to whether manned space flight will eventually become a reality.

Only the man who says no is free

One of the coolest and wisest hours a man has, is just after he awakes in the morning.

Man is lyrical, woman epic, marriage dramatic.

Better be an old maid, a woman with herself as a husband, than the wife of a fool; and Solomon more than hints that all men are fools; and every wise man knows himself to be one.

The poor man wants many things; the covetous man, all.

the Law has made the man and wife one person, and that one person the husband!

I always wanted to live a man’s life in a woman’s body.

Old age is always wakeful; as if, the longer linked with life, the less man has to do with aught that looks like death.
