It is through science that we prove, but through intuition that we discover.
Henri Poincaré
Absolute space, that is to say, the mark to which it would be necessary to refer the earth to know whether it really moves, has no objective existence....

We must make a selection. Is it not better to be guided by utility, by our practical, and more especially our moral, necessities?
Henri Poincare

Henri Poincare
