A theory must be tempered with reality.

Theories, for me, are just about freeing your mind. It doesn't mean the theory is going to work like a scientific theory works. It's about freeing your mind and making you think a different way.

I'm not sure what theory is, unless it's the pursuit of fundamental questions.

You know very well that unless you're a scientist, it's much more important for a theory to be shapely, than for it to be true.

With this sense of the splendour of our experience and of its awful brevity, gathering all we are into one desperate effort to see and touch, we shall hardly have time to make theories about the things we see and touch.

Theories are patterns without value. What counts is action.

Life is so unlike theory.

It is impossible to advance new theories... when you are under the influence of a particular view, or under the pressure of a particular dogma.

There can be theory but, you know, the problem is you've got to be able to test it. So theories are one thing, testing is another.
