Laughter almost ever cometh of things most disproportioned to ourselves and nature. Laughter hath only a scornful tickling.

I said of laughter, “It is mad,” and of pleasure, “What use is it?”

He who laugheth too much, hath the nature of a fool; he that laugheth not at all, hath the nature of an old cat.

There is nothing sillier than a silly laugh.

It is easy to distinguish between the joking that reflects good breeding and that which is coarse—the one, if aired at an apposite moment of mental relaxation, is becoming in the most serious of men, whereas the other is unworthy of any free person, if the content is indecent or the expression obscene.
