What men, in their egoism, constantly mistake for a deficiency of intelligence in woman is merely an incapacity for mastering that mass of small intellectual tricks, that complex of petty knowledges, that collection of cerebral rubber-stamps, which constitute the chief mental equipment of the average male. A man thinks that he is more intelligent than his wife because he can add up a column of figures more accurately, or because he is able to distinguish between the ideas of rival politicians, or because he is privy to the minutiae of some sordid and degrading business or profession. But these empty talents, of course, are not really signs of intelligence; they are, in fact, merely a congeries of petty tricks and antics, and their acquirement puts little more strain on the mental powers than a chimpanzee suffers in learning how to catch a penny or scratch a match.
