Mechanics is the paradise of the mathematical sciences, because by means of it one comes to the fruits of mathematics.

Those who condemn the supreme certainty of mathematics feed on confusion, and can never silence the contradictions of the sophistical sciences which lead to eternal quackery.

The merit of painting lies in the exactness of reproduction. Painting is a science and all sciences are based on mathematics. No human enquiry can be a science unless it pursues its path through mathematical exposition and demonstration.

No human investigation can be called real science if it cannot be demonstrated mathematically.

I have deeply regretted that I did not proceed far enough at least to understand something of the great leading principles of mathematics, for men thus endowed seem to have an extra sense.

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