In this paper I want to compare and contrast Kant and Hegel on reason. While both emphasize the close connection between reason and its ends, motivations and needs, and denounce a futile understanding of reason as a formal, instrumental, or simply logical reasoning, they diverge on how to interpret reason's restlessness, teleology and life. After a section illustrating some uncritical assumptions widespread among readings of Kant, I move to a treatment of their respective views on reason's self-realization (the relation between thought and the I, concepts and intuitions, faith and history), and conclude by showing the main differences in their respective understandings of method, dialectic, limit and ideas.
