Many minds, otherwise good and even noble, are unsound upon the point of Vanity. Nor is the unsoundness one that requires any very sharp observer to detect. It is very often extremely conspicuous; and the merest block-head can discern, and can laugh at, the unfortunate defect in one who is perhaps a great and excellent man. Many minds are off the balance in the respect of Suspiciousness; many in that of absurd Prejudice. Many are unsound in the matters of Silliness, Pettiness, Pettedness, Perversity, or general Unpleasantness and Thrawn-ness. Multitudes of men are what in Scotland is called Cat-witted. I do not know whether the word is intelligible in England. It implies a combination of littleness of nature, small self-conceit, readiness to take offence, determination in little things to have one's own way, and general impracticability. There are men to whom even the members of their own families do not like to talk about their plans and views: who will suddenly go off on a long journey without telling anyone in the house till the minute before they go; and concerning whom their nearest relatives think it right to give you a hint that they are rather peculiar in temper, and you must mind how you talk to them. There are human beings whom to manage into doing the simplest and most obvious duty, needs, on your part, the tact of a diplomatist combined with the skill of a driver of refractory pigs. In short, there are in human beings all kinds of mental twists and deformities. There are mental lameness and broken-windedness. Mental and moral shying is extremely common. As for biting, who does not know it? We have all seen human biters; not merely backbiters, but creatures who like to leave the marks of their teeth upon people present too. There are many kickers; men who in running with others do (so to speak) kick over the traces, and viciously lash out at their companions with little or no provocation. There are men who are always getting into quarrels, though in the main warm-hearted and well-meaning. There are human jibbers: creatures that lie down in the shafts instead of manfully (or horsefully) putting their neck to the collar, and going stoutly at the work of life. There are multitudes of people who are constantly suffering from depression of spirits, a malady which appears in countless forms. There is not a human being in whose mental constitution there is not something wrong; some weakness, some perversion, some positive vice. And if you want further proof of the truth of what I am saying, given by one whose testimony is worth much more than mine, go and read that eloquent and kindly and painfully fascinating book lately published by Dr. Forbes Winslow, on Obscure Diseases of the Brain and Mind; and you will leave off with the firmest conviction that every breathing mortal is mentally a screw.
