The issues of a renewal practice of metaphysics in Kant

The A. wishes to recall that the project to which Kant devoted himself in the Critique of Pure Reason does not consist, as has too often been believed, in abolishing metaphysics, but rather in renewing it on practical foundations. This metaphysics not only corresponds to man's need to go beyond sensible objects to attain the suprasensible, and thus remains closely linked to the hope that our moral merit may have consequences for our future happiness, but it also introduces a completely new conception of objective reality. Differing from the theoretical conditions of objectivity, metaphysical objectivity, which is also practical objectivity, is tied for Kant to the notion of postulate and to the thesis of the superiority of this usage over the theoretical use of reason. Thus something can be real if its existence is necessary to the accomplishment of the necessary and ultimate goal of practical reason. Thus it appears that by limiting theoretical knowledge to experience Kant provided for suprasensible objects thanks to his critique - a domain of practical reality.
