We dance for laughter, we dance for tears, we dance for madness, we dance for fears, we dance for hopes, we dance for screams, we are the dancers, we create the dreams.

Few people are capable of expressing with equanimity opinions which differ from the prejudices of their social environment. Most people are even incapable of forming such opinions.

He who can no longer pause to wonder and stand rapt in awe, is as good as dead; his eyes are closed.

Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.

I fully agree with you about the significance and educational value of as well as history and philosophy of science. So many people today - and even professional - seem to me like someone who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is - in my opinion - the mark of distinction between a mere artisan or specialist and a real seeker after truth.

Now to the term ‘relativity theory.’ I admit that it is unfortunate, and has given occasion to philosophical misunderstandings.

The pursuit of truth and beauty is a sphere of activity in which we are permitted to remain children all our lives.

When I study philosophical works I feel I am swallowing something which I don’t have in my mouth.
