August Wilhelm Rehberg (1757–1836) was a civil servant in Hanover, but he also made several important contributions to the philosophical debates of his time. This chapter contains the first English translation of Rehberg’s review of the second Critique, which was highly influential and read by figures such as Reinhold and possibly Fichte as well. In the review, Rehberg doubts that pure reason can be practical. One of the most important statements of the review is Rehberg’s claim that the feeling of respect must be something sensible and, as such, must contain an element of pleasure, despite what Kant says. Kant was aware of the review and is thought to have responded to it in later works such as the third Critique.
