Não há nenhuma ideia inteligente que possa ganhar aceitação geral sem ser misturada antes com um pouco de estupidez.

Context: The ability of nonintelligent people to understand the most complicated mechanisms and to use them has always been to me a cause of astonishment: their inability to understand simple questions is even more astonishing. The general acceptance of simple ideas is difficult and rare, and yet it is only when simple, fundamental, ideas have been accepted that further progress becomes possible on a higher level.
