The first general criticism, which in itself contains and covers nearly all others, turns on Method. "Conjectures become reasons when they are the most likely that you can draw from the nature of things," and "it is for philosophy in lack of history to determine the most likely facts." In an inductive age this royal road is rigorously closed. Guesses drawn from the general nature of things can no longer give us light as to the particular nature of the things pertaining to primitive men, any more than such guesses can teach us the law of the movement of the heavenly bodies, or the foundations of jurisprudence. Nor can deduction from anything but propositions which have themselves been won by laborious induction, ever lead us to the only kind of philosophy which has fair pretension to determine the most probable of the missing facts in the chain of human history. That quantitative and differentiating knowledge which is science, was not yet thought of in connection with the movements of our own race upon the earth. It is to be said, further, that of the two possible ways of guessing about the early state, the conditions of advance from it, and the rest, Rousseau's guess that all movement away from it has been towards corruption, is less supported by subsequent knowledge than the guess of his adversaries, that it has been a movement progressive and upwards. This much being said as to incurable vice of method, and there are fervent disciples of Rousseau now living who will regard one's craving for method in talking about men as a foible of pedantry, we may briefly remark on one or two detached objections to Rousseau's story. To begin with, there is no certainty as to there having ever been a state of nature of a normal and organic kind, any more than there is any one normal and typical state of society now. There are infinitely diverse states of society, and there were probably as many diverse states of nature. Rousseau was sufficiently acquainted with the most recent metaphysics of his time to know that you cannot think of a tree in general, nor of a triangle in general, but only of some particular tree or triangle.[189] In a similar way he might have known that there never was any such thing as a state of nature in the general and abstract, fixed, typical, and single. He speaks of the savage state also, which comes next, as one, identical, normal. It is, of course, nothing of the kind. The varieties of belief and habit and custom among the different tribes of savages, in reference to every object that can engage their attention, from death and the gods and immortality down to the uses of marriage and the art of counting and the ways of procuring subsistence, are infinitely numerous; and the more we know about this vast diversity, the less easy is it to think of the savage state in general. When Rousseau extols the savage state as the veritable youth of the world, we wonder whether we are to think of the negroes of the Gold Coast, or the
