Hence it inevitably follows logically, as Engels said, ‘that matter remains eternally the same in all its transformations, that none of its attribute… - Benedictus de Spinoza

Spinoza is the Christ of philosophers, and the greatest philosophers are hardly more than apostles who distance themselves from or draw near to this mystery.

Spinoza's "theory" rejected every illusion about ideology, and especially about the number one ideology of that time, religion, by identifying it as imaginary. But at the same time it refused to treat ideology as a simple error, or as naked ignorance, because it based the system of this imaginary phenomenon on the relation of men to the world "expressed" by the state of their bodies. This materialism of the imaginary opened the way to a surprising conception of the First Level of Knowledge: not at all, in fact, as a "piece of knowledge", but as the material world of men as they live it, that of their concrete and historical existence. Is this a false interpretation? In certain respects, perhaps, but it is possible to read Spinoza in such a way. In fact his categories do function, daringly, in this way in the history of the Jewish people, of its prophets, of its religion, and of its politics, where the primacy of politics over religion stands out clearly, in the first work which, after Machiavelli, offered a theory of history. But this theory of the imaginary went still further. By its radical criticism of the central category of imaginary illusion, the Subject, it reached into the very heart of bourgeois philosophy, which since the fourteenth century had been built on the foundation of the legal ideology of the Subject. Spinoza's resolute anti-Cartesianism consciously directs itself to this point, and the famous "critical" tradition made no mistake here. On this point too Spinoza anticipated Hegel, but he went further. For Hegel, who criticized all theses of subjectivity, nevertheless found a place for the Subject, not only in the form of the "becoming-Subject of Substance" (by which he "reproaches" Spinoza for "wrongly" taking things no further than Substance), but in the interiority of the Telos of the process without a subject, which by virtue of the negation of the negation, realizes the designs and destiny of the Idea. Thus Spinoza showed us the secret alliance between Subject and Goal which "mystifies" the Hegelian dialectic.

Twenty-some years ago, when at the age of forty I returned to the study of the Ethics, which had been 'my book' during adolescence, the theoretical climate in which I found myself immersed had changed to such an extent that it was difficult to tell if the Spinoza standing before me then was the same one who had accompanied me in my earliest studies.
