I never wanted to do the same kind of movies over and over anyway, so my theory on it all is I'm just gonna try and dodge the label and keep doing what I am doing.

Matt Damon, actor

Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave nether room nor demand for a theory of probabilities.

In theory one is aware that the earth revolves, but in practice one does not perceive it, the ground upon which one treads seems not to move, and one can live undisturbed. So it is with Time in one's life.

Marcel Proust, author

In the absence of evidence, superstition. It's a Middle Ages thing. That's my theory anyway.

Claude Debussy, composer

They who have reasoned ignorantly, or who have aimed at effecting their personal ends by flattering the popular feeling, have boldly affirmed that 'one man is as good as another;' a maxim that is true in neither nature, revealed morals, nor political theory.

James F. Cooper, novelist

Manfred Eigen, scientist

If the experiments which I urge be defective, it cannot be difficult to show the defects; but if valid, then by proving the theory, they must render all objections invalid.

Isaac Newton, mathematician

Philosophy is not a theory but an activity.

Ludwig Wittgenstein, philosopher

Science is not about control. It is about cultivating a perpetual condition of wonder in the face of something that forever grows one step richer and subtler than our latest theory about it. It is about reverence, not mastery.

Richard Powers, novelist

I think academics are infuriating. For every expert on Shakespeare there is another one to cancel his theory out. It drives you up the wall. I think the greatest form of finding out the truth is through fantasy.
