“It is man’s intelligence that makes him so often behave more stupidly
than the beasts. … Man is impelled to invent theories to account for
what happens in the world. Unfortunately, he is not quite intelligent
enough, in most cases, to find correct explanations. So that when he
acts on his theories, he behaves very often like a lunatic. Thus, no
animal is clever enough, when there is a drought, to imagine that the
rain is being withheld by evil spirits, or as punishment for its
transgressions. Therefore you never see animals going through the absurd
and often horrible fooleries of magic and religion. No horse, for
example would kill one of its foals to make the wind change direction.
Dogs do not ritually urinate in the hope of persuading heaven to do the
same and send down rain. Asses do not bray a liturgy to cloudless skies.
Nor do cats attempt, by abstinence from cat’s meat, to wheedle the
feline spirits into benevolence. Only man behaves with such gratuitous
folly. It is the price he has to pay for being intelligent but not, as
yet, intelligent enough.”—Aldous Huxley
