-Einstein, Albert

-Gellhorn, Martha Ellis

Quiconque craint la contradiction et demeure logique tue en lui la vie. Whoever fears contradiction and remains logical kills life within himself.

-Saint-Exupe¤  ry, Antoine de
Carnets (published1953).

[Science] seldom proceedsinthestraightforward logical manner imagined by outsiders. Instead, its steps forward†are often very human events in which personalities and cultural traditions play major roles.
