Time is what the clock says.

All I want to do is learn to think like God. All the rest is just details.

Smoke like a chimney, work like a horse, eat without thinking, go for a walk only in really pleasant company.

The only real valuable thing is intuition. The intellect has little to do on the road to discovery

In my personal experience I have hardly come to know the wretchedness of mankind better than as a result of the general theory of relativity and everything connected to it. But it doesn't bother me.

I have yet to meet a single person from our culture, no matter what his or her educational background, IQ, and specific training, who had powerful transpersonal experiences and continues to subscribe to the materialistic monism of Western science.
