Deleuze calls Spinoza the “Prince” of philosophers. He devotes two books to him, Spinoza et le probleme de l'expression and Spinoza. Philosophie pratique But Deleuze's entire body of work also gives him an opportunity to work on Spinoza's conceptuality. Deleuze does not arrive at Spinoza by making a leap from the principle of reason to reconquer an original and forgotten past. The immanence of Spinoza is more like an arrow found inadvertently and shot again into the immensity of the universe. We propose to define this timelessness by highlighting the main points of convergence between Deleuze's thought and that of Spinoza. These convergences will be examined using excerpts selected from the five parts of the Ethics in which the following themes will be broached: the principle of reason, panpsychism, experimentation of the body, notion of power, and liberty. We will see how Deleuze gives a new and yet strangely faithful spin to Spinozist thought on which he establishes his notions of pluricosmism, non-human becomings, ethology, deterritorialization, and escape lines.
