"Novalis was cried down as an enthusiastic mystic by the prosaic, and Spinoza as godless by the literalists. It was incumbent upon me to protest against this view of Spinoza, seeing I would review the whole sphere of piety. Something essential would have been wanting in the ex position of my views if I had not in some way said that the mind and heart of this great man seemed deeply influenced by piety, even though it were not Christian piety. The result might have been different, had not the Christianity of that time been so distorted and obscured by dry formulas and vain subtilties that the divine form could not be expected to win the regard of a stranger. This I said in the first edition, somewhat youthfully indeed, yet so that I have found nothing now needing to be altered, for there was no reason to believe that I ascribed the Holy Spirit to Spinoza in the special Christian sense of the word."

“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.”
