philosophizing with Kant, not by starting from his beginning and moving forward in his paths but by inquiring back into what was thus taken for granted (that of which Kantian thinking, like everyone's thinking, makes use as unquestioned and available), when we become conscious of it as presuppositions and accord these their own universal and theoretical interest, there opens up to us, to our growing astonishment, an infinity of ever new phenomena belonging to a new dimension, coming to light only through consistent penetration into the meaning and validity implications of what was thus taken for granted an infinity, because continued penetration shows that every phenomenon attained through this unfolding of meaning, given at first in the life world as obviously existing, itself contains meaning and validity implications whose exposition leads again to new phenomena, and so on.
