"Truly, all the lively, the lively men from the school of Kant, became Neospinozists! In other words, they became Spinozists. The Kantians became Spinozists—what happened? Why did the most prominent Kantians—Fichte, Schelling, Hegel, the best philosophical brains Germany has ever produced—become Spinozists? One will try in vain to find an answer to this question in our histories of philosophy, which do not even ask that legitimate and obvious question. And there is no other answer to it than this one: that it could not have been otherwise, since these truly philosophical men necessarily saw and felt how different Benedict Spinoza's stance within philosophy was from that of Kant, who—to say it in my blunt way—had nothing in common with philosophy."

“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.”
