Quotes from the same author

It is through science that we prove, but through intuition that we discover.
 Henri PoincarĂ©
It is far better to foresee even without certainty than not to foresee at all.
 Henri Poincare
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....
