A serious and good philosophical work could be written consisting entirely of jokes.

A joke is a very serious thing.

Some subjects are so serious that one can only joke about them.

There are things that are so serious that you can only joke about them.

Comedy is simply a funny way of being serious.

Once you realize what a joke everything is, being the Comedian is the only thing that makes sense.

To ridicule philosophy is really to philosophize.

Humor is also a way of saying something serious.

It's all a joke! Everything anybody ever valued or struggled for... it's all a monstrous, demented gag! So why can't you see the funny side? Why aren't you laughing?

Humor is reason gone mad.

A joke is an epigram on the death of a feeling.

Jokes of the proper kind, properly told, can do more to enlighten questions of politics, philosophy, and literature than any number of dull arguments.

All philosophies, if you ride them home, are nonsense, but some are greater nonsense than others.

Everything is funny; the greatest earnestness is funny; even tragedy is funny. And I think what I try and do in my [writing] is to get this recognizable reality of the absurdity of what we do and how we behave and how we speak.
