Understanding physics is child's play when compared to understanding child's play.

The really valuable thing in the pageant of human life seems to me not the political state, but the creative, sentient individual, the personality; it alone creates the noble and the sublime, while the herd as such remains dull in thought and dull in feeling.

It is high time the ideal of success should be replaced with the ideal of service.

The world is a dangerous place to live; not because of the people who are evil, but because of the people who don't do anything about it.

Time is what the clock says.

There is no place in this new kind of physics both for the field and matter, for the field is the only reality.

I believe that a simple and unassuming manner of life is best for everyone, best both for the body and the mind.
