What's your favorite quote and why?

Tomorrow, and tomorrow, and tomorrow
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out brief candle!
Life's but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

In scientific investigations, it is permitted to invent any hypothesis and, if it explains various large and independent classes of facts, it rises to the rank of a well-grounded theory.

How extremely stupid for me not to have thought of that!

We don't replace a theory with one that is better. We replace it with one that is slightly less wrong.

My goal is simple. It is the complete understanding of the Universe.

I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.

What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary

If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed.

Science without religion is lame, religion without science is blind.

Those who do not stop asking silly questions become scientists.

It is not in the stars to hold our destiny, but in ourselves

The human mind treats a new idea the same way the body treats a strange protein;
it rejects it.

Creationists make it sound as though a 'theory' is something you dreamt up after being drunk all night.

The religion that is afraid of science dishonors God and commits suicide.

man will occasionally stumble over the truth, but usually manages to pick himself up, walk over or around it, and carry on.

If I have seen further than others, it is by standing upon the shoulders of giants.

Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world. Science is the highest personification of the nation because that nation will remain the first which carries the furthest the works of thought and intelligence.

Scientists were rated as great heretics by the church, but they were truly religious men because of their faith in the orderliness of the universe.

I may be fat but your ugly and I can diet

The difficulty lies, not in the new ideas, but in escaping the old ones, which ramify, for those brought up as most of us have been, into every corner of our minds.

The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes.

Man is the Reasoning Animal. Such is the claim. I think it is open to dispute. Indeed, my experiments have proven to me that he is the Unreasoning Animal... In truth, man is incurably foolish. Simple things which other animals easily learn, he is incapable of learning. Among my experiments was this. In an hour I taught a cat and a dog to be friends. I put them in a cage. In another hour I taught them to be friends with a rabbit. In the course of two days I was able to add a fox, a goose, a squirrel and some doves. Finally a monkey. They lived together in peace; even affectionately.Next, in another cage I confined an Irish Catholic from Tipperary, and as soon as he seemed tame I added a Scotch Presbyterian from Aberdeen. Next a Turk from Constantinople; a Greek Christian from Crete; an Armenian; a Methodist from the wilds of Arkansas; a Buddhist from China; a Brahman from Benares. Finally, a Salvation Army Colonel from Wapping. Then I stayed away for two whole days. When I came back to note results, the cage of Higher Animals was all right, but in the other there was but a chaos of gory odds and ends of turbans and fezzes and plaids and bones and flesh--not a specimen left alive. These Reasoning Animals had disagreed on a theological detail and carried the matter to a Higher Court.
