"I would have said that Eichmann was profoundly, egregiously stupid, and for me stupidity is not the same as having a low IQ. Here I rather agree with Kant, that stupidity is caused, not by brain failure, but by a wicked heart. Insensitiveness, opacity, inability to make connections, ofter accompanied by low "animal" cunning. One cannot help feeling that this mental oblivion is , by the heart or the moral will--an active preference, and that explains why one is so irritated by stupidity, which is not the case when one is dealing with a truly backward individual."
