288 LAW AND FREEDOM IN HISTORY which once, perhaps, had more or less satisfactorily fulfilled their regu- lative purpose, came to defeat the intentions of statesmanship by es- caping from its control and rankling into enormities which were bound, sooner or later, to liquidate themselves either by destroying the society on which they had come to prey or alternatively by moving a society whose life was now at stake to terminate this series of ever more de- structive wars between parochial states by allowing all the contending pieces but one to be swept off the board. The self-amortization of a cyclic rhythm which thus proves to be the dominant tendency in struggles for existence between parochial states has previously come to our notice in our study of the disintegrations of civilizations; and it is not surprising that there should be this visible affinity between the respective rhythms of two historical processes that are manifestly bound up with one another. Our study1 of the break- downs in which the disintegrations of civilizations have originated has shown us that a frequent occasion, symptom, and even veritable cause of breakdown has been the outbreak of a war between parochial states in which a perennial evil that has previously been kept under control and been practised with moderation now disconcertingly lights up, in one of its periodical recurrences, to a degree of intensity that is so unprece- dentedly severe as to constitute a deadly danger to the society's survival. In the pre-Alexandrine chapter of Hellenic history, for example, the Atheno-Peloponnesian 'reduplicated general war' of 431-404 B.C. was a scourge of this unprecedentedly lethal kind, as contrasted with the rela- tively moderate warfare with one another in which the Athenian and the Lacedaemonian faction in an Hellenic body politic had been indulging down to that date since their split in 478 B.C. In the pre-Confucian chap- ter of Sinic history, similarly, the great war of 634-628 B.C., in which the principal belligerents were Tsin and Ch'u, marked a corresponding cli- macteric crisis in a series of cycles of warfare between parochial states. In our examination of three series of this kind, we have also noticed3 that the replacement of a litter of contending parochial states by a single oecumenical power is apt to be followed, not by an entire cessation of recurrent outbreaks of anarchic violence, but by their translation from the previous form of wars between parochial states into the alternative form of civil wars and social disorders; and, if we thus find that the establishment of a universal state does not inevitably bring to an end the alternating rhythm of War and Peace generated by an antecedent Ba- lance of Power between parochial states, it is more patently evident that this achievement of constructive statesmanship, magnificent though it is, does not avail to reverse, and so avert, a process of disintegration which it temporarily arrests. We have observed3 that—in the histories of civilizations down to the time of writing—the disintegrations of civilizations, like the struggles for existence between parochial states through which the breakdowns of civilizations had been precipitated, had run their course in a series of rhythmic fluctuations; and an empirical survey of ten examples—leaving 1 In IV, passim, in vol. iv. a On pp. 271 and 283. above. 3 In Y. vi. 378-321.
