As I considered the matter carefully it gradually came to light that all those matters only were referred to mathematics in which order and measurements are investigated, and that it makes no difference whether it be in numbers, figures, stars, sounds or any other object that the question of measurement arises. I saw consequently that there must be some general science to explain that element as a whole which gives rise to problems about order and measurement, restricted as these are to no special subject matter. This, I perceived was called 'universal mathematics'.

But possibly I am something more than I suppose myself to be.

Science is practical philosophy.

I desire to live in peace and to continue the life I have begun under the motto 'to live well you must live unseen

There is nothing more ancient than the truth.

Conquer yourself rather than the world.

The only secure knowledge is that I exist.
