Stupidity

Only two things are infinite, the universe and human stupidity, and I’m not sure about the former

In politics stupidity is not a handicap.

Prejudices are what fools use for reason

Last words are for fools who haven't said enough

Lottery: A tax on people who are bad at math

I love fools' experiments. I am always making them

The person with least knowledge talks most

It is human nature to think wisely and act foolishly

Every man is a damn fool for at least five minutes every day; wisdom consists in not exceeding the limit

The doctor sees all the weakness of mankind; the lawyer all the wickedness, the theologian all the stupidity

A fool and his money are soon parted

A prudent question is one-half of wisdom

The religious man fears, the man of honor scorns, to do an ill action

None but blockheads copy each other

The hours of folly are measured by the clock, but of wisdom no clock can measure.

There is as much trickery required to grow rich by a stupid book as there is folly in buying it

There is no class so pitiably wretched as that which possesses money and nothing else

Education is a crutch with which the foolish attack the wise to prove that they are not idiots

Stupidity gets up early; that is why events are accustomed to happening in the morning.

Stupidity is an elemental force for which no earthquake is a match
