During the Middle Ages, wild animals were often believed to be devil-possessed. Wolves, moles, and caterpillars were tried in courts and executed. A story is told of Saint Dominic catching a sparrow, plucking it alive, and rejoicing in his triumph over the powers of darkness. By 1531 a legist argued that “rural pests would simply laugh” at civil-court censure but “have greater fear” of the Church’s power of anathema and should be excommunicated.

A Hindu myth holds that the universe began as soul in the form of man, who looked around, saw nothing, and felt afraid. “Therefore,” goes the story, “one who is all alone is afraid.” The man reflected, “Since there is nothing other than me, of what am I afraid?” His fear vanished, since a being only “becomes afraid of a second.” But he felt no joy, so he created a female companion: a second being, whom he could fear.

Describing phalanx warfare, Thucydides wrote that “fear makes every man want to do his best to find protection for his unarmed side in the shield of the man next to him on the right.” The soldier farthest right must try to “keep his own unarmed side away from the enemy, and his fear spreads to the others who follow his example.” The effect of this fear, wrote the historian: “the right wing tends to get unduly extended.”

Fear of witches among the Kaguru of Tanzania is extreme: some prefer to defecate inside their huts rather than be alone in the dark at night.

Franklin Delano Roosevelt, who gave thirty so-called fireside chats over twelve years, was afraid of fire and refused to lock his door while sleeping so as to ensure easy escape, which he would often practice by dropping quickly from his bed or chair and crawling to the exit.
