Not predestined for knowledge. – There is a stupid humility that is by no means rare, and those afflicted with it are altogether unfit to become votaries of knowledge. For as soon as a person of this type perceives something striking, he turns on his heels, as it were, and says to himself, ‘You have made a mistake! Where were your senses? This cannot be the truth!’ And then, instead of looking and listening more keenly again, he runs away, as if intimidated, from the striking thing and tries to shake it from his mind as fast as possible. For his inner canon says, ‘I want to see nothing that contradicts the prevalent opinion. Am I made to discover new truths? There are already too many old ones.’
Nietzsche, The Gay Science
