Irrational fear plays an extraordinarily large part in the instinctive emotional life of most people. In its pathological forms, as persecution mania, anxiety complex, or what not, it is treated by alienists. But in milder forms it is common among those who are considered sane. It may be a general feeling that there are dangers about, more correctly termed “anxiety”, or a specific dread of things that are not dangerous, such as mice or spiders.[3] It used to be supposed that many fears were instinctive, but this is now questioned by most investigators. There are apparently a few instinctive fears--for instance, of loud noises--but the great majority arise either from experience or from suggestion. Fear of the dark, for example, seems to be entirely due to suggestion. Most vertebrates, there is reason to think, do not feel instinctive fear of their natural enemies, but catch this emotion from their elders. When human beings bring them up by hand, the fears usual among the species are found to be absent. But fear is exceedingly infectious: children catch it from their elders even when their elders are not aware of having shown it. Timidity in mothers or nurses is very quickly imitated by children through suggestion. Hitherto, men have thought it attractive in women to be full of irrational terrors, because it gave men a chance to seem protective without incurring any real danger. But the sons of these men have acquired the terrors from their mothers, and have had to be afterwards trained to regain a courage which they need never have lost if their fathers had not desired to despise their mothers. The harm that has been done by the subjection of women is incalculable; this matter of fear affords only one incidental illustration.
