Both men [Yeshu/Jesus and Spinoza] were exceptionally bright, and men of spirit. They could have become major spiritual forces in Judaism had they be… - Benedictus de Spinoza

Instead of engaging in this rather boring academic exercise of opposing Spinoza and Levinas, what I want to accomplish is a consciously old-fashioned Hegelian reading of Spinoza - what both Spinozeans and Levinasians share is radical anti-Hegelianism. My starting hypothesis is that, in the history of modern thought, the triad of paganism-Judaism-Christianity repeats itself twice, first as Spinoza-Kant-Hegel, then as Deleuze-Derrida-Lacan. Deleuze deploys the One-Substance as the indifferent medium of multitude; Derrida inverts it into the radical Otherness which differs from itself; finally, in a kind of "negation of negation," Lacan brings back the cut, the gap, into the One itself. The point is not so much to play Spinoza and Kant against each other, thus securing the triumph of Hegel; it is rather to present the three philosophical positions in all their unheard-of radicality - in a way, the triad Spinoza-Kant-Hegel does encompass the whole of philosophy.

The Ethics is a book of concepts (the second kind of knowledge), but also of affects (the first kind) and percepts (the third kind) too. Thus the paradox in Spinoza is that he's the most philosophical of philosophers, the purest in some sense, but also the one who more than any other addresses non-philosophers and calls forth the most intense non-philosophical understanding. That is why absolutely anyone can read Spinoza, and be very moved, or see things quite differently afterward, even if they can hardly understand Spinoza's concepts. Conversely, a historian of philosophy who understands only Spinoza's concepts doesn't fully understand him.

Love is nothing but Joy with the accompanying idea of an external cause (Ethics, part III, proposition 13, scholium).
