Here we have a sufficient explanation of the general superiority of bachelors, so often noted by students of mankind—a superiority so marked that it is difficult, in all history, to find six first-rate philosophers who were married men. The bachelor’s very capacity to avoid marriage is no more than a proof of his relative freedom from the ordinary sentimentalism of his sex—in other words, of his greater approximation to the clear headedness of the enemy sex. He is able to defeat the enterprise of women because he brings to the business an equipment almost comparable to their own. Herbert Spencer, until he was fifty, was ferociously harassed by women of all sorts. Among others, George Eliot tried very desperately to marry him. But after he had made it plain, over a long series of years, that he was prepared to resist marriage to the full extent of his military and naval power, the girls dropped off one by one, and so his last decades were full of peace and he got a great deal of very important work done. 21. The Effect on the Race It is, of course, not well for the world that the highest sort of men are thus selected out, as the biologists say, and that their superiority dies with them, whereas the ignoble tricks and sentimentalities of lesser men are infinitely propagated. Despite a popular delusion that the sons of great men are always dolts, the fact is that intellectual superiority is inheritable, quite as easily as bodily strength; and that fact has been established beyond cavil by the laborious inquiries of Galton, Pearson and the other anthropometricians of the English school. If such men as Spinoza, Kant, Schopenhauer, Spencer, and Nietzsche had married and begotten sons, those sons, it is probable, would have contributed as much to philosophy as the sons and grandsons of Veit Bach contributed to music, or those of Erasmus Darwin to biology, or those of Henry Adams to politics, or those of Hamilcar Barca to the art of war. I have said that Herbert Spencer’s escape from marriage facilitated his life-work, and so served the immediate good of English philosophy, but in the long run it will work a detriment, for he left no sons to carry on his labours, and the remaining Englishmen of his time were unable to supply the lack. His celibacy, indeed, made English philosophy co-extensive with his life; since his death the whole body of metaphysical speculation produced in England has been of little more, practical value to the world than a drove of bogs. In precisely the same way the celibacy of Schopenhauer, Kant and Nietzsche has reduced German philosophy to feebleness.
