Hobbes and Hume in relation to Kant

Hobbes and Hume on the imagination can initiate a discussion of empiricism in the 17th and 18th centuries: here, however, it provides the opportunity to focus on Kant's attempt to overcome the limits of their sense originating, naturalist ethics. I argue the general point that Kant's response to his predecessors, both empiricist and non-empiricists, is to modify their focus on nature without falling into skepticism; indeed, his speculative metaphysics also is a response to classical ontological metaphysics. Kant by providing two realms or perspectives, a natural and a noumenal, avoids many difficulties resulting from Hobbes and Hume's starting point in sense leading to imagination and a non-normative reason. Yet, challenged by Herder and the romantics, he uses a sort of residual view of the imagination in relation to the freedom of the noumenal, which results in difficulties for his speculative, noumenal metaphysics.
