Ssu-ma Ch'ien's many-volumed history of China established the frame within which Chinese history continued to be written almost to the present day.

Like Christianity, Buddhism explained suffering. In forms that established themselves in China, Buddhism offered the same sort of comfort to bereaved survivors and victims of violence or of disease as Christian faith did in the Roman world. Buddhism of course originated in India, where disease incidence was probably always very high as compared with civilizations based in cooler climates; Christianity, too, took shape in the urban environments of Jerusalem, Antioch, and Alexandria where the incidence of infectious disease was certainly very high as compared to conditions in cooler and less crowded places. From their inception, therefore, both faiths had to deal with sudden death by disease as one of the conspicuous facts of human life. Consequently, it is not altogether surprising that both religions taught that death was a release from pain, and a blessed avenue of entry upon a delightful afterlife where loved ones would be reunited, and earthly injustices and pains amply compensated for.

An irresistible cycle seemed to operate, repeating patterns of the ancient world where civil strife and war brought disaster... I surmised that patterned and predictable changes were in turn rooted in the very nature of civilization—the ineluctable breaker of custom and eroder of moral codes, and itself a product and expression of rapid technological and social change.
