 In regard to the normative conditions under which hope is rational, Kant is sensitive to a theoretical and practical dimension: He focuses on hopes that are (necessarily) connected with a moral duty and thus involve a practical necessity. From a theoretical point of view, Kant’s main concern is to show that these hopes are not impossible. While he holds that empirical evidence permits hoping as long as there is no proof to the contrary (AE 8:309f.), this minimal criterion is connected to the idea that hope is based on transcendental assumptions (i.e., the existence of God, immortality, and a teleology of nature) (Blöser 2020b).
