“Spinoza: The Velocities of Thought” was a 14-lecture seminar given from December 1980 to March 1981. In this seminar, Deleuze revisits his examination of Baruch Spinoza’s philosophy. Deleuze had previously published two books on Spinoza: Expressionism in Philosophy: Spinoza (Spinoza et le problème de l'expression, 1968), and Spinoza: Practical Philosophy (Spinoza Philosophie pratique, 1970, 2nd ed. 1981). The majority of these lectures were given the same year as the publication of the second edition of the latter title.

In the 20 January 1981 lecture, topics of discussion include: Spinoza's Letters to Blyenbergh; Nature and the composition of relationships; action and the image of things; eternity, instantaneity and duration; power and affection; the difference in nature between affection and affect; French philosopher Henri Bergson; the increase, decrease and composition of power; Ethics, Book IV; the meeting of bodies; joy and sadness; Nietzsche, power and sadness; degrees of power, essence and eternity; Spinoza's Letters to Meyer; infinity; geometry; the German philosopher Gottfried Wilhelm Leibniz; reason; Rousseau; the German-Swiss psychiatrist and philosopher Karl Jaspers; the capability of a body; self-destruction and the calculus of relationships; and prophetic signs, social and linguistic.
