The Four Causes of Human Laughter

The Four Causes of Human Laughter is Screwtape’s classification of Joy, Fun, the Joke Proper, and Flippancy, presented as a practical guide to the different moral effects of laughter. His argument unsettles the assumption that amusement serves Hell simply because people laugh: Joy and Fun can foster qualities the demons oppose, while humor becomes useful when it makes shame disappear and habitual Flippancy turns seriousness itself into a target. The four categories distinguish not just kinds of comedy but ways of feeling, relating, and judging conduct.

A taxonomy of laughter

Screwtape introduces the distinction after hearing that the two new friends of the patient have brought him into their wider circle, a group he describes as reliable scoffers and worldlings. Their being great laughers is not, he warns, enough to establish that laughter benefits the demons. The question is what produces the laughter and what it makes possible.

Joy is laughter among friends and lovers reunited on the eve of a holiday. Although adults may supply jokes as a pretext, their ease in laughing at even small witticisms suggests that the jokes are not the true cause. Screwtape admits that he does not know what that cause is. He associates it with something in music and with an analogue in Heaven: an acceleration in the rhythm of experience that is opaque to demonic understanding. Because this laughter does the demons no good, he says it should be discouraged; its existence also offends Hell’s preferred realism, dignity, and austerity.

Fun is related to Joy but arises as a kind of emotional froth from the play instinct. It may occasionally distract people from something God would have them feel or do, so it can be used opportunistically. Yet Screwtape regards it as unreliable in itself: Fun promotes charity, courage, contentment, and other qualities he identifies as evils. Its spontaneous social energy is thus not automatically available for infernal purposes.

The Joke Proper and moral shame

The Joke Proper depends on a sudden perception of incongruity. Screwtape distinguishes its underlying operation from the mere use of indecent material, which he says second-rate tempters rely on too heavily. People differ in how sexual subject matter and laughter interact: for one group, a joke about sex can dispel desire because the incongruity becomes funny; for another, laughter and lust are excited at once, and incongruity supplies a pretext for sexual talk. A tempter must discover which group the patient belongs to without allowing the patient to discover the distinction. The example makes humor’s effect contingent, not universal; the same material can frustrate one temptation and serve another.

Screwtape locates the more dependable use of humor in its ability to destroy shame. He singles out the English attachment to having a sense of humor, which makes a perceived lack of it an unusual source of embarrassment and lends humor the authority of an all-consoling, all-excusing grace. The social label can then alter how conduct is received: letting others pay may be called meanness, while boasting about it jokingly can make the same behavior seem comic. Cowardice can be presented as funny through humorous exaggeration and grotesque gestures; cruelty can be redescribed as a practical joke.

The danger is not simply that people tell bawdy or blasphemous jokes. More consequentially, a person may learn that almost anything can be done without disapproval—and even with the admiration of others—if it is treated as a joke. The surrounding seriousness about humor helps conceal the temptation: a warning that there may be too much joking can itself be dismissed as puritanical or as evidence of a deficient sense of humor. Humor’s moral force therefore lies partly in the social permission it creates, not only in the joke’s subject matter.

Flippancy as a defense against seriousness

Flippancy is Screwtape’s preferred category because it is economical. A genuine joke about virtue, or about anything else, requires cleverness; by contrast, anyone can be trained to talk as if virtue were funny. In flippant company, no one needs to make a joke explicitly. Serious subjects are discussed in a manner that assumes their ridiculous side has already been found, so the dismissal precedes any particular comic observation.

Repeated over time, this manner of speaking builds what Screwtape calls armor against God. Unlike other forms of laughter, it carries none of their associated risks for the demons: it is far removed from Joy, deadens rather than sharpens the intellect, and generates no affection among those who practice it. The contrast with Fun is especially sharp. Fun can promote courage, charity, and contentment; Flippancy makes seriousness seem unserious while offering neither Joy’s fellowship nor even the liveliness of genuine humor.

The argument’s moral contrast

The taxonomy is a piece of infernal advice, and its categories are defined by their usefulness or danger to the demons rather than by a neutral account of comedy. That viewpoint produces an ironic reversal: qualities ordinarily understood as virtues appear in Screwtape’s vocabulary as threats, while the erosion of shame and the deadening of thought count as successes. His own admission that Joy’s source is unknown also marks a limit in the demonic account. The demons can study and exploit some human responses, but the laughter associated with reunion, music, and Heaven exceeds their explanation.

The four causes consequently form a scale of moral and social effects rather than a simple division between laughter and seriousness. Joy and Fun can strengthen fellowship or virtue; the Joke Proper can be harmless, ineffective, or useful depending on its effect and its audience; and Flippancy operates as a habitual way of preventing serious subjects from being taken seriously. Screwtape’s decisive warning is about the change in judgment that occurs when misconduct is granted comic cover: laughter may accompany a deed, but the more effective temptation is to make humor appear to absolve it.
