原版英文小说On generation and corruption
OUR next task is to study coming-to-be and passing-away. We are to distinguish the causes, and to state the definitions, of these processes considered in general-as changes predicable uniformly of all the things that come-to-be and pass-away by nature. Further, we are to study growth and \'alteration\'. We must inquire what each of them is; and whether \'alteration\' is to be identified with coming-to-be, or whether to these different names there correspond two separate processes with distinct natures.
