  Weyl’s a priori and a posteriori distinction must  not be confused with Kant’s distinction. Weyl (1949a, 134) remarks:  “In the case of physical space it is possible to  counterdistinguish aprioristic and aposterioristic features in a  certain objective sense without, like Kant, referring to their  cognitive source or their cognitive character.” Weyl makes the  same remark in (Weyl, 1922b, 266). See also the discussion in  §4.5.8.
