Abstract
This article approaches the largely known four objections that Hegel held against Kant: the formalism of moral principle, the criticism of autonomy and formalism, the objection of the abstract universalism in Kant′s ethics, and the terrorism of the pure reason. The purpose is to determine the extent of these objections in front of Kant′s critical thought. At the end of the text, I will support that in spite of different misunderstandings about Kant′s ethics; however Hegel inherited us a great lesson that even crosses the contemporary ethical thought: the radical contraposition between justice (virtue) and the Sittlichkeit (the concrete and effective ethics) that leads us to the loss of the basic moral phenomenon.
