From the invention of Jesus to the Epicurian Christianity. The writing of Occidental philosophy’s history isn’t neutral: the conception of a knowledge and thinking founder Grece excludes the thoughts that preceded it in the time, an idealistic domination – mainly Platonic – and its continuation with christian spiritualism and German Idealism: the leading historiography is clearly platonic. We can yet imagine and propose a counter-story of Philosophy who claims another lineage: materialist, hedonist, nominalistic, atheistic, sensualist, etc. etc. And one can live this philosophy with the preoccupation of a systematic thinking.
