Friedrich von Schiller

Against stupidity the gods themselves struggle in vain.
(Mit der Dummheit kaempfen Goetter selbst vergebens)

Random words, heard by chance, turn to hard facts in the eyes of a man of imagination, if there's any fire burning in his heart.

Keep true to the dreams of thy youth.

With stupidity the gods themselves struggle in vain.

Against stupidity the gods themselves contend in vain.

It does not prove a thing to be right because the majority say it is so.
