Desire is the actual essence of man, in so far as it is conceived, as determined to a particular activity by some given modification of itself.

We have gathered within the walls of the Communist Academy and are devoting this evening to Spinoza's memory not from the considerations which guided the organizers of the Hague celebration but from quite different considerations; for us Spinoza is essentially a great atheist and materialist. In this appraisal of Spinoza I am in complete agreement with Plekhanov. In all of Plekhanov's works, as I know, the fundamental thought is emphasized that Marxism, considered as a world‑view, is nothing other than a 'variety of Spinozism.' But I shall set this question aside for the moment, in order to cite a passage from Plekhanov's preface to my Introduction to Philosophy (the preface was written in 1914) in which he sharply criticizes the historians of philosophy who have numbered Spinoza among the idealists. 'With the present universal prevalence of idealism,' he says, 'it is quite natural that the history of philosophy should now be interpreted from the idealistic point of view. As a consequence, Spinoza his long since been numbered among the idealists. Hence, certain readers will probably be very much surprised to learn that I understand Spinoza in the materialistic sense; yet this is the only correct understanding of Spinozism. 'As early as 1843 Feuerbach asserted his fundamental conviction that the teaching of Spinoza was "an expression of the materialistic conceptions of the modern age." Of course, even Spinoza did not escape the influence of his time. His materialism, as Feuerbach remarked, was clothed in a theological costume, but the important thing was that, in any case, he eliminated the dualism of mind and nature. Nature in Spinoza is called God, but extension is one of the attributes of this God. And this constitutes the radical difference between Spinozism and idealism.'

...Spinozism conquers a place in contemporary philosophy, no longer simply as an historical index of reference but as an operative paradigm. This occurs because Spinozism always represents a full stop in the critique of modernity, for it opposes a conception of the collective subject, of love and the body as powers of presence to the conception of the subject-individual, of mediation and the transcendental, which inform the concept of the modern from Descartes to Hegel and Heidegger. Spinozism is a theory of time torn away from purposiveness, the foundation of an ontology conceived as a process of constitution. It is on this basis that Spinozism acts as the catalyst of an alternative in the definition of the modern. But why should one deprecate a centuries-old position of radical refusal of the forms of modernity by calling it by the feeble name of 'alternative'? [...] Certain contemporary authors have felicitously anticipated our definition of Spinoza's anti-modernity. Thus Althusser: "Spinoza's philosophy introduced an unprecedented theoretical revolution into the history of philosophy, probably the greatest philosophical revolution of all time, to the point that we can regard Spinoza as Marx's only direct ancestor, from the philosophical standpoint." Why? Because Spinoza is the founder of an absolutely original conception of praxis without teleology, because he thought the presence of the cause in its effects and the very existence of structure in its effects and in presence.
