Today history is no more than a thin thread of the remembered stretching over an ocean of the forgotten, but time moves on, and an epoch of millennia will come which the inextensible memory of the individual will be unable to encompass; whole centuries and millennia will therefore fall away, centuries of paintings and music, centuries of discoveries, of battles, of books, and this will be dire, because man will lose the notion of his self, and his history, unfathomable, unencompassable, will shrivel into a few schematic signs destitute of all sense.
