The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error.

True ignorance is not the absence of knowledge, but the refusal to acquire it.

The growth of knowledge depends entirely upon disagreement.

In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality.

The question is not how to get good people to rule; THE QUESTION IS: HOW TO STOP THE POWERFUL from doing as much damage as they can to us.

If you can't say it simply and clearly, keep quiet, and keep working on it till you can.

The best thing that can happen to a human being us to find a problem, to fall in love with that problem, and to live trying to solve that problem, unless another problem even more lovable appears.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride, or laziness of mind.

A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.

Violent passions are formed in solitude. In the busy world no object has time to make a deep impression.

Some are born richWhile others poor

to learn and not to do is really not to learn. To know and not to do is really not to know.

Sometimes the world seems like a big hole. You spend all your life shouting down it and all you hear are echoes of some idiot yelling nonsense down a hole.

I-I am going to be a storm-a flame- I need to fight whole armies alone; I have ten hearts; I have a hundred arms; I feel too strong to war with mortals- BRING ME GIANTS!

If you desire ease, forsake learning. If you desire learning, forsake ease.

A video taped stage performance is just - you know, it's never gonna be the same as it is if you're sitting there live in the theatre.

If I just concentrate I can walk into memory's store and find the right shelf with the right film and disappear into it.

Maybe there's a chance to get back to grown-up films. Anything that uses humor and dramatic values to deal with human emotions and gets down to what people are to people.
