Morality makes stupid.- Custom represents the experiences of men of earlier times as to what they supposed useful and harmful - but the sense for custom (morality) applies, not to these experiences as such, but to the age, the sanctity, the indiscussability of the custom. And so this feeling is a hindrance to the acquisition of new experiences and the correction of customs: that is to say, morality is a hindrance to the development of new and better customs: it makes stupid.
An enormous amount of modern ingenuity is expended on finding defences for the indefensible conduct of the powerful. As I have said above, these defences generally exhibit themselves most emphatically in the form of appeals to physical science. And of all the forms in which science, or pseudo-science, has come to the rescue of the rich and stupid, there is none so singular as the singular invention of the theory of races.
The English mind is always in a rage. The intellect of the race is wasted in the sordid and stupid quarrels of second-rate politicians or third-rate theologians.
When a thing is said to be not worth refuting you may be sure that either it is flagrantly stupid - in which case all comment is superfluous - or it is something formidable, the very crux of the problem.
The more stupid one is, the closer one is to reality. The more stupid one is, the clearer one is. Stupidity is brief and artless, while intelligence squirms and hides itself. Intelligence is unprincipled, but stupidity is honest and straightforward.
There's a lot we should be able to learn from history. And yet history proves that we never do. In fact, the main lesson of history is that we never learn the lessons of history. This makes us look so stupid that few people care to read it. They'd rather not be reminded. Any good history book is mainly just a long list of mistakes, complete with names and dates. It's very embarrassing.
I have frequently detected myself in such kind of mistakes... in a total misapprehension of character at some point or other: fancying people so much more gay or grave, or ingenious or stupid than they really are, and I can hardly tell why, or in what the deception originated. Sometimes one is guided by what other people say of them, without giving oneself time to deliberate and judge.
