 Although Yorck provides only an unfinished sketch of the empirical course of the history of life, he marks three decisive turning-points: (1) The breakthrough to philosophy and science on the basis of the dominant stance of the psychological function of representation or cognition, primarily in ancient Greece and India; (2) the predominance of willing in the Roman and Jewish stance towards the world; and (3) the focal centrality of feeling and interiority in Christianity, particular in the Reformation, i.e., Luther. Somewhat like Hegel, Yorck holds that history unfolds through particular primary stances towards life which then become dominant in particular historical  peoples.[17]
