Humor is not an unconditional virtue; its moral character depends on its object. To laugh at the contemptible, is a virtue; to laugh at the good, is a hideous vice. Too often, humor is used as the camouflage of moral cowardice.

There are two types of cowards in this connection. One type is the man who dares not reveal his profound hatred of existence and seeks to undercut all values under cover of a chuckle, who gets away with offensive, malicious utterances and, if caught, runs for cover by declaring: “I was only kidding.”

The other type is the man who dares not reveal or uphold his values and seeks to smuggle them into existence under cover of a chuckle, who tries to get away with some concept of virtue or beauty and, at the first sign of opposition, drops it and runs, declaring: “I was only kidding.”

In the first case, humor serves as an apology for evil; in the second—as an apology for the good.
