 Before he ever wrote “in his own name” in Difference and Repetition and Logic of Sense, Deleuze wrote a series of works on figures in the history of philosophy (Hume, Bergson, Nietzsche, Kant, and Spinoza). In writing these works, Deleuze sought to unearth the presuppositions he absorbed in his education; chief among them, he felt, was a deep-seated privilege of identity over difference. Deleuze thus set about trying to accelerate however he could a departure from Hegel, whom he saw as emblematic of that privilege. Deleuze attacks Hegel and others in what we can call—though Deleuze did not—the “identitarian” tradition first of all by means of a radicalized reading of Kant, whose genius, as Deleuze explains in Kant’s Critical Philosophy (1963), was to have conceived of a purely immanent critique of reason—a critique that did not seek “errors” of reason produced by external causes, but rather “illusions” that arise from within reason itself by the illegitimate (transcendent) uses of the syntheses of consciousness. Deleuze characterized his own work as a philosophy of immanence, arguing that Kant himself had failed to realize fully the ambitions of his critique, for at least two reasons: first, the failure to pursue a fully immanent critique, and second, the failure to propose a genetic account of real experience, resting content with the account of the conditions of possible experience.
