unreasoned. It seems at times as if nations were submitted to secret forces analogous to those which compel the acorn to transform itself into an oak or a comet to follow its orbit.
What little insight we can get into these forces must be sought for in the general course of the evolution of a people, and not in the isolated facts from which this evolution appears at times to proceed. Were these facts alone to be taken into consideration, history would seem to be the result of a series of improbable chances. It was improbable that a Galilean carpenter should become for two thousand years an all-powerful God in whose name the most important civilisations were founded; improbable, too, that a few bands of Arabs, emerging from their deserts, should conquer the greater part of the old Graco-Roman world, and establish an empire greater than that of Alexander; improbable, again, that in Europe, at an advanced period of its development, and when authority throughout it had been systematically hierarchised, an obscure lieutenant of artillery should have succeeded in reigning over a multitude of peoples and kings.
