 The question—and the basic strategy for answering it—go back, of course, to Kant, who put forward the following crucial idea: that the very factors that make us finite (our subjection to space, time, causality, etc.) are also conditions necessary for the possibility of empirical knowledge. Our finitude is, therefore, simultaneously founded and founding (positive and fundamental, as Foucault puts it). The project of modern (Kantian and post-Kantian) philosophy—the analytic of finitude—is to show how this is possible.
