The highest wisdom has but one science - the science of the whole - the science explaining the whole creation and man's place in it.

The whole of science is nothing more than a refinement of everyday thinking.

Man is an animal with primary instincts of survival. Consequently, his ingenuity has developed first and his soul afterwards. The progress of science is far ahead of man's ethical behavior.

To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.

Science is a wonderful thing if one does not have to earn one's living at it.

Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.
