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

Natural science will in time incorporate into itself the science of man, just as the science of man will incorporate into itself natural science: there will be one science.

Science is the century-old endeavour to bring together... perceptible phenomena... through systematic thought.

Science without religion is lame. Religion without science is blind.

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

It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature.
