Lasting harmony with a woman (was) an undertaking in which I twice failed rather disgracefully.

I am content in my later years. I have kept my good humor and take neither myself nor the next person seriously.

The real difficulty, the difficulty which has baffled the sages of all times, is rather this: how can we make our teaching so potent in the motional life of man, that its influence should withstand the pressure of the elemental psychic forces in the individual?

Make everything as simple as possible, but not simpler. A man should look for what is, and not for what he thinks should be. We cannot solve our problems with the same thinking we used when we created them. A question that sometimes drives me hazy: am I or are the others crazy? Any intelligent fool can make things bigger and more complex... It takes a touch of genius - and a lot of courage to move in the opposite direction. All religions, arts and sciences are branches of the same tree. It's not that I'm so smart, it's just that I stay with problems longer.

Condemnation without investigation is the height of ignorance

The thinking it took to get us into this mess is not the same thinking that is going to get us out of it.

The thing is, not to stop questioning.
