Among its findings, which historically changed the face of philosophy, are that traditional metaphysics is over (Aviii–x, Axix–xx, Bxiv–xv), and that proofs for God’s existence are done with (A631–42/B659–70). Discoveries later made in neuroscience confirm Kant’s insights and affirm that perception results from interaction, whereby pathways organize affecting data (B1, A15/B29, A50–51/B74–5, B113, B148–9), and that the subject of organized experience—the synthetic unity of apperception—poses the hard problem of consciousness (B154–9).
