History is the science of things which are not repeated.
Science without religion is lame, religion without science is blind.
A fool's brain digests philosophy into folly, science into superstition, and art into pedantry. Hence University education.
Freedom is absolutely necessary for the progress in science and the liberal arts.
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.
Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.

A systematic revolution of basic concepts begins with Einsteinian science. In the very detail of its concepts a relativism of the rational and the empirical is established. Science then undergoes what Nietzsche called 'an upheaval of concepts,' as if the earth, the universe, things, possessed a different structure from the fact that their explanation rests upon new foundations. All rational organization is 'shaken' when the fundamental concepts undergo dialectical transformation.
