An idea that is not dangerous is unworthy of being called an idea at all.

Indeed, the probabilities are that the more insincere the man is, the more purely intellectual will the idea be, as in that case it will not be coloured by either his wants, his desires, or his prejudices.

It's not hard to get the ideas when they come. They just come... it's painful waiting for them.

Every single work of art is the fulfillment of a prophecy; for every work of art is the conversion of an idea into an image.

Music is the art... which most completely realizes the artistic idea and is the condition to which all the other arts are constantly aspiring.

I played with an idea, and grew willful; tossed it into the air; transformed it; let it escape and recaptured it; made it iridescent with fancy, and winged it with paradox.

An idea that isn't risky is hardly worth calling an idea.
