Abstract
This paper aims to establish theoretical guidelines for understanding the relationship between ethics and anthropology in Kant's thought. Contrary to a particular line of interpretation dominant in specialized research on Kant, this article seeks to promote a historical-philosophical investigation, which contextualizes in Kant's thought the moment when three philosophical currents intersected, causing the guidelines of his debate about the concept of autonomy and perfectibility, namely: the philosophies of Hutcheson, Wolff and Rousseau. In this first part, Kant's discussion with Hutcheson and Wolff is discussed. From a more specific point of view, in this first part, the present article goes through Kant's reflections between 1755 and 1764 in order to present how the need to think about a relation between ethics and anthropology is constituted within Kantian thought.
