I never made one of my discoveries through the process of rational thinking

It has become appallingly obvious that our technology has exceeded our humanity.

Peace cannot be kept by force. It can only be achieved by understanding. You cannot subjugate a nation forcibly unless you wipe out every man, woman, and child. Unless you wish to use such drastic measures, you must find a way of settling your disputes without resort to arms.

Development of Western science is based on two great achievements: the invention of the formal logical system (in Euclidean geometry) by the Greek philosophers, and the discovery of the possibility to find out causal relationships by systematic experiment (during the Renaissance). In my opinion, one has not to be astonished that the Chinese sages have not made these steps. The astonishing thing is that these discoveries were made at all.

In a healthy nation there is a kind of dramatic balance between the will of the people and the government, which prevents its degeneration into tyranny.

I never allow myself to become discouraged under any circumstances. The three great essentials to achieve anything worthwhile are first, hard work, second, stick-to-ittiveness, third, common sense.

It's not that life has been easy, perfect or exactly as expected. I just choose to be happy and grateful no matter how it all turns out. If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed.
