When God gives you an idea, you must act immediately on it.

People's hearts are like deep wells. Nobody knows what's at the bottom. All you can do is guess from what comes floating to the surface every once in a while.

We would like the truth to be revealed to us by novel signs, not by a sentence, a sentence similar to those which we have constantly repeated to ourselves. The habit of thinking prevents us at times from experiencing reality, immunises us against it, makes it seem no more than another thought. There is no idea that does not carry in itself its possible refutation, no word that does not imply its opposite.

People don't understand what happiness is, so they have an idea of what will make them happy, but it never does.

Nothing represents a man better than his ideas.

Hollywood has the idea that movies have to be dumb. But especially movies for or about teenagers have to be really dumb!

That which makes people dissatisfied with their condition, is the chimerical idea they form of the happiness of others.

Make a start, even if you have a controversial idea!

I'm going to marry a Jewish woman because I like the idea of getting up Sunday morning and going to the deli.

There is immense power in an idea, because it unites people. It motivates them toward change. But the real power lies in their unity, in coming together – if enough can be rallied to a cause, no matter how ridiculous, it will be seen and heard.
