Aristotle defined man as a rational and political animal. But there are also passages in his work that indicate another less remarked upon definition. In Parts of Animals, he writes, “When people are tickled, they quickly burst into laughter, and this is because the motion quickly penetrates to this part, and even though it is only gently warmed, still it produces an independent movement in the intelligence which is recognizable.” He continues to argue that touch is the most primary sense and human beings are uniquely privileged in possessing the sharpest sense of touch because of the delicate nature of their skin. He says that, although other animals have more advanced smell or hearing, a man’s sense of touch is the most fine-tuned. This leads to some of us to think that tickling is a side effect of the hyper-sensitivity of human touch. Thanks to our sophisticated and discriminating access to the world around us, we are particularly vulnerable to tickling.
However, this “privilege” did not last long as many scientific researches have refuted Aristotle’s claim about how tickling could only effect human beings. It has been found that monkeys are ticklish too, and a recorded laughter-like ultrasonic chirping in tickled rats also exists. But, the most famous ticklish animal is the trout as it would fall into a trance-like state when its underbelly is lightly rubbed. In Shakespeare’s Twelfth Night, Maria says, while planning to trick Malvolio, “Lie thou there; for here comes the trout that must be caught with tickling.”
Neuroscientist Robert Provine posed a rather elaborate speculation which links tickling with both humorous laughter and the prehistoric birth of comedy. He writes, “I forge recklessly into the paleohumorology fray, proposing my candidate for the most ancient joke—the feigned tickle (Real tickling is disqualified because of its reflexive nature). The ‘I’m going to get you’ game of the threatened tickle is practiced by human beings worldwide and is the only joke that can be told equally well to a baby human and a chimpanzee. Both babies and chimps ‘get’ this joke and laugh exuberantly.” His argument is that proper ticklish laughter is not actually funny because it is too much of an automatic or neurological reaction. To make tickling funny, it needs to be distanced from reflex. It is the suspended gesture that gets a laugh – the real gesture might get one slapped. Therefore, a child will wriggle and squirmed when tickled, but they will actually laugh only if they perceive the tickling as a mock attack, a caress in a mildly aggressive and irritating disguise.
The ambivalence of tickling, a delight that can quickly become excruciating, would seem particularly well suited to describe the concept of pleasure-in-pain that so fascinated thinkers from Plato, Nietzsche, Freud etc. They agree that tickling serves as an alternate way of thinking about pleasure, as titillation and excitation. Nietzsche put it, “What is the best life? To be tickled to death.” – I hope someone would do a research on whether this man was ever tickled in his life. However, he is not wrong about this. Foot tickling for sexual arousal was used in the Muscovite palaces and courts for centuries. Many of the Czarinas (Catherine the Great, Anna Ivanovna, Elizabeth and others) were participants of this activity. The practice was so popular that eunuchs and women were employed as full time foot ticklers. They developed this skill so well that their occupations brought prestige and good pay. Anna Leopoldovna had at least six ticklers at her feet. While the ticklers performed their task, they also told bawdy stories and sang obscene ballads. This was done to work the ladies up to an erotic pitch so that they could meet their husbands or lovers in a sex impassioned mood.
But can one actually die from tickling? Yes. When children enthusiastically tickle one another, it serves the double purpose of inspiring peer bonding and honing reflexes and self-defense skills. In 1984, psychiatrist Donald Black noted that many ticklish parts of the body, such as the neck and the ribs, are also the most vulnerable in combat. He inferred that children learn to protect those parts during tickle fights, a relatively safe activity. However, the tickling itself can be torture enough. Tickle torture can be an extended act of tickling where the recipient of the tickling would view it as a long time or tickling of an intense nature. This can be due to the length of time they are tickled, the intensity of the tickling or the areas that are being tickled. This can simply be a 30-second tickle applied to the victim’s bare feet, which can seem like a much longer time if the feet are very ticklish.
Mythology is littered with spirits who uses tickling as a torture device. In Inuit mythology, Mahaha is a maniacal demon that terrorized parts of the arctic. This creature is described as a thin sinewy being, ice blue in colour and cold to the touch. His eyes are white and they peer through the long stringy hair that hangs in his face. This demon is always smiling and giggling – taking pleasure in tickling its victims to death with sharp vicious nails attached to its long bony fingers. All of its victim have a similar expression on their dead faces – a twisted frozen smile.
A Leshy is a spirit of the Slavic forests. They serve as the protectors of the various forests and its animals, having a close bond with gray wolves and often being accompanied by bears. They naturally are the form of a large human-looking being, but can shape-shift into any plant or animal. They have long hair and beards made of living grass and vines. In the center of a forest, they are a tree-like giant, who camouflage nicely with their long limbs, grassy eyebrows, and no detectable shadows. A leshy has the ability to imitate voices of people familiar to wanderers.They will cry out and get their victims to wander deeper into forests or caves. Being tickled to death by a Leshy has been known to happen. This is most likely because they don’t know when “fun” is enough and wind up accidentally killing their victims.
Of course, if something exists in mythology, it would also exist, up to a point, in history. Chinese tickle torture is an ancient form of torture practiced by the Chinese, in particular the courts of the Han Dynasty. Chinese tickle torture was a punishment for nobility since it left no marks and a victim could recover relatively easily and quickly. In ancient Japan, those in positions of authority could administer punishments to those convicted of crimes that were beyond the criminal code. This was called shikei, which translates as ‘private punishment.’ One such torture was kusuguri-zeme: “merciless tickling.” Dutch physiologist Joost Meerloo recounts an especially cruel tickle torture employed by the ancient Romans. On the scaffold, the soles of a victim’s feet were covered with a salt solution so that a goat, attracted by the salt, would lick it off with his rough tongue and continually tickle the skin. By so doing, the salty skin was gradually rasped away. Then, the wounded skin would again be covered with the biting salt solution—ad infinitum, till the victim died from the torture.
In Laurent Joubert’s Renaissance treatise on laughter, he reports hearing “of a young man whom two girls were tickling importunately to the point that he no longer uttered a word. They thought he had fainted until, thunderstruck, they realized he was dead, asphyxiated.” A news item in Illustrated Police News, 11 December 1869, recounts the story of a young wife whose husband, his name was Michael Puckridge, claimed that he had a cure for her varicose veins. After he persuaded her to allow herself to be tied to a plank, she found that her husband had instead devised a plan to tickle her into insanity. The plan worked as she was institutionalized as a result of her husband’s diabolical featherwork.
