 Following the experimental confirmation of the general theory in 1919, few Kantians attempted to retain, unadulterated, all of the components of Kant’s epistemological views. Several examples will suffice to indicate characteristic “immunizing strategies” (Hentschel 1990). The Habilitationsschrift of E. Sellien (1919), read by Einstein in view of his criticism expressed in an October 1919 letter to Moritz Schlick (Howard 1984: 625), declared that Kant’s views on space and time pertained solely to intuitive space; as such Kant’s views were impervious to the measurable spaces and times of Einstein’s empirical theory. The work of another young Kantian philosopher, Ilse Schneider, personally known to Einstein, affirmed that Kant merely had held that the space of three-dimensional Euclidean geometry is the space in which Newton’s gravitational law is valid, thus no objections to Kant could be marshalled from the four-dimensional variably curved spacetimes of general relativity. Furthermore, Einstein’s cosmology (1917b) of a finite but unbounded universe was regarded as in complete accord with the “transcendental solution” to the First Antinomy in the Second Book of the Transcendental Dialectic. Her verdict was that apparent contradictions between relativity theory and Kantian philosophy disappear on closer examination of both doctrines (Schneider 1921: 71–75).
