Pure mathematics is, in its way, the poetry of logical ideas.

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.

As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.

The process of scientific discovery is, in effect, a continual flight from wonder.

All science would be superfluous if the outward appearance and the essence of things directly coincided.

Forget that blind ambition, and learn to trust your intuition.
