The systems of location of space and time are necessarily com-
mon [to all], they must be, as principles of individuation, titles
15 for intersubjective cognizability in order that in general the same
objectivity be cognizable as the same. By the same token, all pri-
mary qualities—duration, spatial form, relative positions in space—
must be cognizable intersubjectively, despite their sensible, also
lived bodily-psychophysically determined manners of givenness.
Edmund #Husserl, First Philosophy, 406
