Grave as is the situation, it is not yet irreparable, any more than Greece's condition was hopeless after Ægospotami. It was not the Peloponnesian War which sealed Hellas's doom, but the cycle of political anarchy and moral chaos of which the Peloponnesian War was merely the opening phase. Our world is too vigorous for even the Great War, of itself, to prove a mortal wound. The white world thus still has its choice. But it must be a positive choice. Decisions--firm decisions--must be made. Constructive measures--drastic measures--must be taken. Above all: time presses, and drift is fatal. The tide ebbs. The swimmer must put forth strong strokes to reach the shore. Else--swift oblivion in the dark ocean. CHAPTER IX THE SHATTERING OF WHITE SOLIDARITY The instinctive comity of the white peoples is, as I have already said, perhaps the greatest constant of history. It is the psychological basis of white civilization. Cohesive instinct is as vital to race as gravitation is to matter. Without them, atomic disintegration would alike result. In speaking of race-instinct, I am not referring merely to the ethnic theories that have been elaborated at various times. Those theories were, after all, but attempts to explain intellectually the urge of that profound emotion known to sociologists as the "consciousness of kind." White race-consciousness has been of course perturbed by numberless internal frictions, which have at times produced partial inhibitions of unitary feeling. Nevertheless, when really faced by non-white opposition, white men have in the past instinctively tended to close their ranks against the common foe. One of the Great War's most deplorable results has been an unprecedented weakening of white solidarity which, if not repaired, may produce the most disastrous consequences. During the nineteenth century the sentiment of white solidarity was strong. The great explorers and empire-builders who spread white ascendancy to the ends of the earth felt that they were apostles of their race and civilization as well as of a particular country. Rivalries might be keen and colonial boundary questions acute; nevertheless, in their calmer moments, the white peoples felt that the expansion of one white nation buttressed the expansion of all.
