I always disagree, however, when people end up saying that we can only combat Communism, Fascism or what not if we develop an equal fanaticism. It appears to me that one defeats the fanatic precisely by not being a fanatic oneself, but on the contrary by using one's intelligence.
Unanimity of opinion is a very ominous phenomenon, and one characteristic of our modern mass age. It destroys social and personal life, which is based on the fact that we are different by nature and by conviction. To hold different opinions and to be aware that other people think differently on the same issue shields us from Godlike certainty which stops all discussion and reduces social relationships to those of an ant heap. A unanimous public opinion tends to eliminate bodily those who differ, for mass unanimity is not the result of agreement, but an expression of fanaticism and hysteria. In contrast to agreement, unanimity does not stop at certain well-defined objects, but spreads like an infection into every related issue.
