This study addresses the space of the human inclinations within the Practical Philosophy of Kant, and to observe how the education, according to the kantian view, is placed in this question. We aim to address the theme of human inclinations (sensations, passions, appetites), particularly, in the works Foundations of the Metaphysics of Morals and Critique of Practical Reason. Later, seeking possible relationships with the remarks made by Kant about ambient of the inclinations on lectures On Education. An attempt to first highlight the complementarity of the works which constitute the practical philosophy of Kant (in view of its architecture, arrangement and division) and, second, to face the claim that Kant's moral philosophy requires the entire removal of the inclinations (of any inclination) so that man's actions have an authentic moral value. Accordingly, there is the Kantian moral while rigorous, insensitive or empty.
