Abstract
The idea that noumena or things in themselves causally affect our sensibility, and thus provide us with sensations, has been rejected on two basic grounds: It is unintelligible because distinguishes between appearance and reality in such a way that things cannot in principle appear as they really are, and it requires applying the concept of causality trans-phenomenally, contra Kant’s Schematism. I argue that noumenal causality is intelligible and is required out of fidelity to Kant’s texts and doctrines. Kant’s theory of meaning and his transcendental reflection on sensibility show how Kant legitimately can speak about, and determine that, our passive sensibility must be causally affected by noumena. Kant’s analysis of agency shows that Kant’s practical philosophy requires noumenal causality, both from a first- and from a third-person perspective. These points ground my criticisms of Buchdahl and Allison’s view of affection, and Strawson and Sandberg’s view of meaning.
