Watch the Hedgehogs Struggle
Environment
"A number of porcupines huddled together for warmth on a cold day in winter; but, as they began to prick one another with their quills, they were obliged to disperse."
Schopenhauer's Parable on Intimacy
"A number of porcupines huddled together for warmth on a cold day in winter; but, as they began to prick one another with their quills, they were obliged to disperse."
In his 1851 essay collection Parerga and Paralipomena, Arthur Schopenhauer described a group of porcupines (later hedgehogs in Freud's retelling) on a cold winter's day. They huddled together for warmth—but their quills pricked each other, forcing them apart. Yet the cold drove them back together, and the cycle repeated until they found the optimal distance: close enough for warmth, far enough to avoid pain.
Schopenhauer concluded: "The need for society which springs from the emptiness and monotony of men's lives, drives them together; but their many unpleasant and repulsive qualities and insufferable drawbacks once more drive them apart." The solution? Politeness and good manners—the social equivalent of the hedgehogs' optimal distance.
Try it: Lower the temperature and watch the hedgehogs cluster tighter (and suffer more pricks). Increase quill sharpness and watch them maintain greater distance. The simulation finds equilibrium—just like relationships do.
