wrote Dietrich Bonhoeffer in 1943. He was a German pastor known for his staunch resistance to the Nazi dictatorship, for which he was imprisoned and later hanged. In prison, he wrote ‘Prisoners of War’, later published as ‘letters and papers from prison’, in which he tried to understand how Germany had entered such dark times.
“You can fight evil” he said. “It always makes men uncomfortable, if nothing worse. Evil carries with itself the seeds of its own destruction. To prevent willful malice, you can always erect barriers to stop its spread.”
“But against stupidity we have no defense. Neither protests nor force can touch it. Reasoning is of no use. Facts that contradict personal prejudices can simply be disbelieved — indeed, the fool can counter by criticizing them, and if they are undeniable, they can just be pushed aside as trivial exceptions. So the fool, as distinct from the scoundrel, is completely self-satisfied. In fact, they can easily become dangerous, as it does not take much to make them aggressive. To persuade the stupid person with reason is senseless and dangerous.” — Dietrich Bonhoeffer
Bonhoeffer points out three important facts about stupidity:
First, it is a moral rather than an intellectual defect. ‘There are men of great intellect who are fools and men of low intellect who are anything but fools’. If you know that something is evil, but choose to ignore it because others ignore it, you are not only stupid but you are also immoral.
Second, stupidity is acquired rather than congenital. ‘The power of one needs the folly of the other. It is apparent that a very strong upsurge of power is so terrific that it deprives men of an independent judgment, and they give up trying […] to assess the new state of affairs for themselves. […] One feels, somehow, especially in conversation with him, that it is impossible to talk to the man himself […]. Instead, one is confronted with a series of slogans, watchwords, and the like, which have acquired power over him. He is under a curse, he is blinded, his very humanity is being prostituted and exploited.’ — Dietrich Bonhoeffer
And third, it is less common in the unsociable or the solitary than in individuals who are inclined to sociability. It is a sociological problem rather than psychological.
