Spinoza is the anomaly. The fact that Spinoza, atheist and damned, does not end up behind bars or burned at the stake, like other revolutionary innovators of the sixteenth and seventeenth centuries, can only mean that his metaphysics effectively represents the pole of an antagonistic relationship of force that is already solidly established: The development of productive forces and relations of production in seventeenth-century Holland already comprehends the tendency toward an antagonistic future. Within this frame, then, Spinoza's materialist metaphysics is the potent anomaly of the century: not a vanquished or marginal anomaly but, rather, an anomaly of victorious materialism, of the ontology of a being that always moves forward and that by constituting itself poses the ideal possibility for revolutionizing the world.

I make this chief distinction between religion and superstition, that the latter is founded on ignorance, the former on knowledge; this, I take it, is the reason why Christians are distinguished from the rest of the world, not by faith, nor by charity, nor by the other fruits of the Holy Spirit, but solely by their opinions, inasmuch as they defend their cause, like everyone else, by miracles, that is by ignorance, which is the source of all malice; thus they turn a faith, which may be true, into superstition.

Spinoza was a Jew, It is a certified fact that he was born and educated as a Jew. But should we mention the names of other men, perhaps of equal rank with Spinoza, who were likewise bom and educated as Jews, and whom scarcely any Jew would dare to remember proudly and gratefully as a Jew? We need not mention these names, and can indeed regard the proposition as proven, that the Jewish origin and education of a great man, taken by themselves, do not give us the right to claim his greatness for Judaism. Therefore, if one disregards the fact that Spinoza was born and educated as a Jew {a fact from which perhaps not much can be concluded), and if in addition one is not satisfied with vague speculations on Spinoza's Jewish cast of mind; if therefore one wants to know clearly and distinctly where Judaism is lodged in Spinoza's thought, that is, which of Spinoza's decisive ideas bear a peculiarly Jewish imprint — then one will turn with deserved trust to those scholars who have endeavored to determine the Jewish sources of Spinoza's doctrine.
