Stupidity is when you won't fear God but you will fear the Frog.

They are all stupid peasants, and the worst of all peasants are the so-called educated. These people should not only be prevented from learning to read, but from learning to talk as well. No need to prevent them from thinking; nature has done that.

El hombre no domina la naturaleza, sino que, fundándose sobre el conocimiento de unas cuantas leyes y secretos naturales, se ha erigido en la posición de dueño de aquellos otros seres que carecen de tal conocimiento.

The problem with the world is that everyone does not have a brain, but everyone does have a tongue.

Stupidity of man makes the world burn.

What a strange creature is a laughing fool,
As if a man were created to no use
But only to show his teeth.
