 Margolis acknowledges that the historized "nature" of the human—and therefore of truth, of judgment, of reality, and the rest - is not his own discovery, but criticizes most previous versions of historicism as falling victim to some theological or teleological yearning, as in Hegel's "Geist", Marx's utopianism, or Heidegger's history of being.In Margolis's view, the truth claims of earlier historical epochs are given their historical weight, from our own historical present, our own truth claims regarding theirs are subject to our own bias and blindness, but ours must still be legitimated as best we can legitimate them, taking into account as far as humanly possible – though never overcoming - our limited horizon via self-critique.Margolis claims that five philosophical themes have gathered momentum from the time of Kant on.
