Provisional hypothesis that Heidegger’s philosophy is reducible to a form of psychologism

He states that the ecstases of time reduced to place is an inauthentic or vulgar understanding of time. However it is precisely the place of space that allows a sign to indicate temporal meaning. The meaning of  the “hardness” of a diamond is in its future would-be instantiation of hardness met with in experience. Heidegger’s Da-sein is Grue (new riddle of induction). Temporality and meaning are abductive, not inductive, thus Da-sein is psychologistic.
