There are so many different kinds of stupidity, and cleverness is one of the worst.

Too clever is dumb.

And not only the pride of intellect, but the stupidity of intellect. And, above all, the dishonesty, yes, the dishonesty of intellect. Yes, indeed, the dishonesty and trickery of intellect.

There is no greater cruelty than a genius stumbling over something idiotic.

How terrible is wisdom when it brings no profit to the wise.

The wise man through an excess of wisdom is made a fool.

Human intelligence was more trouble than it was worth. It was more destructive than creative, more confusing than revealing, more discouraging than satisfying, more spiteful than charitable.

I am sick to death of cleverness. Everybody is clever nowadays. You can’t go anywhere without meeting clever people. The thing has become an absolute public nuisance. I wish to goodness we had a few fools left.

I am enormously wise and abysmally ignorant

Wisdom in the young is as unattractive as frivolity in the elderly.

Cleverness is not wisdom.

There is nothing worse than aggressive stupidity.

artificial intellegance is no match for natural stupidity

If there is one thing I can't stand, it is stupidity. I always say that stupidity is the Sin against the Holy Ghost.
