CUSTOMS AND BEAUTY.—In justice to custom it must not be overlooked that, in the case of all those who conform to it whole-heartedly from the very start, the organs of attack and defence, both physical and intellectual, begin to waste away; _i.e._ these individuals gradually become more beautiful! For it is the exercise of these organs and their corresponding feelings that brings about ugliness and helps to preserve it. It is for this reason that the old baboon is uglier than the young one, and that the young female baboon most closely resembles man, and is hence the most handsome.—Let us draw from this our own conclusions as to the origin of female beauty! 26. ANIMALS AND MORALS.—The rules insisted upon in polite society, such, for example, as the avoidance of everything ridiculous, fantastic, presumptuous; the suppression of one’s virtues just as much as of one’s most violent desires, the instant bringing of one’s self down to the general level, submitting one’s self to etiquette and self-depreciation: all this, generally speaking, is to be found, as a social morality, even in the lowest scale of the animal world—and it is only in this low scale that we see the innermost plan of all these amiable precautionary regulations: one wishes to escape from one’s pursuers and to be aided in the search for plunder. Hence animals learn to control and to disguise themselves to such an extent that some of them can even adapt the colour of their bodies to that of their surroundings (by means of what is known as the “chromatic function”). Others can simulate death, or adopt the forms and colours of other animals, or of sand, leaves, moss, or fungi (known to English naturalists as “mimicry”).
