I don't think the human mind can comprehend the past and the future. They are both just illusions that can manipulate you into thinking there's some kind of change.

It is not history which uses men as a means of achieving - as if it were an individual person - its own ends. History is nothing but the activity of men in pursuit of their ends.

History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.
