| A. Mammals but probably not ladybirds share the same system of categories | B. An artifact possessed of reason would have the same system of fundamental categories as a human being | ||
|
C. If bats don't share the same system of fundamental categories as human beings their experience must be fundamentally different too.
|
D. Criteria of rationality vary from culture to culture. | ||
Kant holds that the fundamental system of categories he endeavours to set out must be in place for experience to be possible at all, and that they are coextensive with rationality.
A. seems wrong because he wouldn't have thought of reptiles as possessing rationality.
C is too mild. The categories Kant is positing he holds are necessary for experience of any kind.
D. The categories Kant is positing are more fundamental than cultural differences. He maintains that rational beings, irrespective of culture, share the same fundamental categories.
B seems the best answer. You may think something made by humans could never possess rationality, and Kant might agree with you, but it follows from Kant's position that IF you could show an artifact possessd rationality then you would have to say also that it possessed the same fundamental categories as us.
