Positivism is the only school which has given a definite significance to these two conceptions, whether regarded from their scientific or their social aspect. With regard to Progress, the assertion will hardly be disputed, no definition of it but the Positive ever having yet been given. In the case of Order, it is less apparent; but, as I have shown in the first chapter, it is no less profoundly true. All previous philosophies had regarded Order as stationary, a conception which rendered it wholly inapplicable to modern politics. But Positivism, by rejecting the absolute, and yet not introducing the arbitrary, represents Order in a totally new light, and adapts it to our progressive civilization. It places it on the firmest possible foundation, that is, on the doctrine of the invariability of the laws of nature, which defends it against all danger from subjective chimeras. The Positivist regards artificial Order in Social phenomena, as in all others, as resting necessarily upon the Order of nature, in other words, upon the whole series of natural laws. [Progress, the development of Order] But Order has to be reconciled with Progress: and here Positivism is still more obviously without a rival. Necessary as the reconciliation is, no other system has even attempted it. But the facility with which we are now enabled, by the encyclopædic scale, to pass from the simplest mathematical phenomena to the most complicated phenomena of political life, leads at once to a solution of the problem. Viewed scientifically, it is an instance of that necessary correlation of existence and movement, which we find indicated in the inorganic world, and which becomes still more distinct in Biology. Finding it in all the lower sciences, we are prepared for its appearance in a still more definite shape in Sociology. Here its practical importance becomes more obvious, though it had been implicitly involved before. In Sociology the correlation assumes this form: Order is the condition of all Progress; Progress is always the object of Order. Or, to penetrate the question still more deeply, Progress may be regarded simply as the development of Order; for the order of nature necessarily contains within itself the germ of all possible progress. The rational view of human affairs is to look on all their changes, not as new Creations, but as new Evolutions. And we find this principle fully borne out in history. Every social innovation has its roots in the past; and the rudest phases of savage life show the primitive trace of all subsequent improvement.
