Sonhos de um Visionário e suas contribuições para a ética de Kant

In this paper, I argue that the main aspects of the metaphysics of morals were already developed in Kant’s thought in 1764-1766. Based on the Dreams of a Spirit -seer elucidated by Dreams of Metaphysics, published in 1766, I will try to demonstrate the first traces of a new understanding about the metaphysics as the problem of the will in Kantian thought from a analysis of the spiritual world. Accordingly, this conception will present the first published evidences about the concepts of autonomy, freedom, formalism, categorical imperative, kingdom of ends and moral sentiment.
