"...Elsewhere I have shown that La Mettrie and Diderot – each after his own fashion – arrived at a world-outlook that was a ‘brand of Spinozism’, that is, a Spinozism without the theological appendage that distorted its true content. It would also be easy to show that, inasmuch as we are speaking of the unity of subject and object, Hobbes too stood very close to Spinoza. That, however, would be taking us too far afield, and, besides, there is no immediate need to do that. Probably of greater interest to the reader is the fact that today any naturalist who has delved even a little into the problem of the relation of thinking to being arrives at that doctrine of their unity which we have met in Feuerbach."

“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.”
