Swift's attacks of vertigo began in his youth. He attributed his illness to an over-consumption of fruit when he was twenty-one. Swift knew better than that. Even if we assume that medical science in the eighteenth century was stupid and backward, Swift was too intelligent to believe that an early period of indigestion accounted for the suffering which afflicted him all his life. He knew, or suspected and feared, what was the matter with him. In 1699, when he was thirty-two, he wrote some resolutions, headed "when I come to be old." Among them is this: "Not to be fond of children or let them come near me hardly." Stephen quotes a friendly commentator as saying: "We do not fortify ourselves with resolutions against what we dislike but against what we feel in our weakness we have reason to believe we are really inclined to." That friendly commentator was right and understood human nature, though he had never lived (Stephen does not name him) to hear about libido, suppression, defence, inversion, and other wise words now current. Stephen goes wrong, it seems to me, in his following friendly commentation: "Yet it is strange that a man should regard the purest and kindliest of feelings as a weakness to which he was too much inclined." I have not space to quote the rest, which is on page 31 of Stephen in the English Men of Letters. Swift was not fighting against a weakness, he was fighting against a strength. He resolves "not to marry a young woman." In a letter he calls a woman's children her "litter," and that has been quoted by some critics as an example of his brutality. He loves Tom, Dick, and Harry but he hates mankind. Is it not clear? He can not have what he wants, and what he wants is what normally results in children, in more mankind. His resolution, superficially harsh and misanthropic, is a masked, or inverted, expression of desire. Such expression is not, of course, peculiar to literary satirists, but it should be remembered that Swift had supremely the ironic trick of thought, the gift of saying a thing by saying exactly the opposite.
