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

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

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

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

The man of science is a poor philosopher.
