"Spinoza, as George Kline tells us, was a favorite with Russian Marxists: "Spinoza has received more attention from Soviet writers than any other pre-Marxian philosopher with the possible exception of Hegel" . Even before the revolution, Plechanov, a founding father of Russian Marxism and of the Russian Social-Democratic party, took to Spinoza, considering that Marxism itself was a variety of Spinozism, or, a Spinozism stripped of its theological attire. A. M. Deborin, who quotes Plechanov on this point in his essay in Kline's collection, and also his contribution, "Spinozismus and Marxismus", in Chronicon Spinozanum 5 , where he further quotes Plechanov, and declares that "Marxism, the leading revolutionary doctrine of the present, which is materialistic through and through, stems in its philosophical world-view from Spinozism". Deborin founded a whole school around this notion, and one of his colleagues even called Spinoza "Marx without a beard". Stalin later denounced this school — an ultima ratio in Soviet intellectual life — and it declined."

“Humanam impotentiam in moderandis et coercendis affectibus servitutem voco; homo enim affectibus obnoxius sui juris non est sed fortunæ in cujus potestate ita est ut sæpe coactus sit quanquam meliora sibi videat, deteriora tamen sequi.”

“Meum institutum non est verborum significationem sed rerum naturam explicare”

“Hic conatus aliquid agendi et etiam omittendi ea sola de causa ut hominibus placeamus, vocatur ambitio præsertim quando adeo impense vulgo placere conamur ut cum nostro aut alterius damno quædam agamus vel omittamus; alias humanitas appellari solet.”

“[B]y Natura naturans we must understand what is in itself and is conceived through itself, or such attributes of substance as express an eternal and infinite essence, that is … God, insofar as he is considered as a free cause. But by Natura naturata I understand whatever follows from the necessity of God's nature, or from God's attributes, that is, all the modes of God's attributes insofar as they are considered as things which are in God, and can neither be nor be conceived without God.”
