The older I grow the more I distrust the familiar doctrine that age brings wisdom. It is my honest belief that I am no wiser to-day than I was five or ten years ago; in fact, I often suspect that I am appreciable _less_ wise. Women can prevail over me to-day by devices that would have made me hoof them out of my studio when I was thirty-five. I am also an easier mark for male swindlers than I used to be; at fifty I’ll probably be joining clubs and buying Mexican mine stock. The truth is that every man goes up-hill in sagacity to a certain point, and then begins sliding down again. Nearly all the old fellows that I know are more or less balmy. Theoretically, they should be much wiser than younger men, if only because of their greater experience, but actually they seem to take on folly faster than they take on wisdom. A man of thirty-five or thirty-eight is almost woman-proof. For a woman to marry him is a herculean feat. But by the time he is fifty he is quite as easy as a Yale sophomore. On other planes the same decay of the intelligence is visible. Certainly it would be difficult to imagine any committee of relatively young men, of thirty or thirty-five, showing the unbroken childishness, ignorance and lack of humor of the Supreme Court of the United States. The average age of the learned justices must be well beyond sixty, and all of them are supposed to be of finished and mellowed sagacity. Yet their knowledge of the most ordinary principles of justice often turns out to be extremely meager, and when they spread themselves grandly upon a great case their reasoning powers are usually found to be precisely equal to those of a respectable Pullman conductor. 3 _Duty_ Some of the loosest thinking in ethics has duty for its theme. Practically all writers on the subject agree that the individual owes certain unescapable duties to the race—for example, the duty of engaging in productive labor, and that of marrying and begetting offspring. In support of this position it is almost always argued that if _all_ men neglected such duties the race would perish. The logic is hollow enough to be worthy of the college professors who are guilty of it. It simply confuses the conventionality, the pusillanimity, the lack of imagination of the majority of men with the duty of _all_ men. There is not the slightest ground for assuming, even as a matter of mere argumentation, that _all_ men will ever neglect these alleged duties. There will always remain a safe majority that is willing to do whatever is ordained—that accepts docilely the government it is born under, obeys its laws, and supports its theory. But that majority does not comprise the men who render the highest and most intelligent services to the race; it comprises those who render nothing save their obedience.
