The question whether, after all, the world really does progress is not one that can be settled by an intellectual demonstration of any kind. It is possible to prove that mankind has gained and is gaining in material power, in knowledge, and in the extent and diversity of social organization; that history shows an enlarging perspective and that the thoughts of men are, in truth, “broadened with the process of the suns”: but it is always possible to deny that these changes are progress. We seem to mean by this term something additional, a judgment, in fact, that the changes, whatever they may be, are on the whole _good_. In other words progress, as commonly understood, is essentially a moral category, and the question whether it takes place or not is one of moral judgment. Nothing of this kind is susceptible of incontrovertible demonstration, because the moral judgment is not bound by definite intellectual processes, nearly the same in all minds, but takes in the most obscure and various impulses of human nature. Suppose you compare the state of the first white settlers in America, narrow and hard, physically, mentally, and socially, with the comparatively easy and spacious life of their descendants at the present time; or contrast the life of a European peasant, dwelling in mediæval ignorance and bondage, with that of the same peasant and his family after they have emigrated to the United States and come to a full share in its intelligence and prosperity. It may seem clear to most people that these changes, which are like those the world in general has been undergoing, are for the better; but the matter is quite debatable. The simpler lot of the pioneer and the peasant can easily be made to appear desirable, and there are, and no doubt always will be, those who maintain that we are no better off than we were. Development, I should say, can be proved. That is, history reveals, beyond question, a process of enlargement, diversification, and organization, personal and social, that seems vaguely analogous to the growth of plant and animal organisms; but whether we are to write our moral indorsement on the back of all this is another matter. Is it better to be man or the marine animal, “resembling the larvæ of existing Ascidians,”[83] from which he is believed to have descended? In the end it comes down to this: is life itself a good thing? We see it waxing and shining all about us, and most of us are ready to pronounce that it is good; but the pessimist can always say: “To me it is an evil thing, and the more of it the worse.” And there is no way of convincing him of error.
