It is the simple hypotheses of which one must be most wary; because these are the ones that have the most chances of passing unnoticed.
Henri PoincareTolstoi explains somewhere in his writings why, in his opinion, โScience for Science's sakeโ is an absurd conception. We cannot know all the facts, since they are practically infinite in number. 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
