"To express myself briefly, Goethe was the Spinoza of poetry. The whole of Goethe's poetry is filled with the same spirit that is wafted toward us from the writings of Spinoza. There is no doubt whatsoever that Goethe paid undivided allegiance to Spinoza's doctrine. At any rate, he occupied himself with it throughout his entire life; in the first part of his memoirs as well as in the last volume, recently published, he frankly acknowledged this. I don't remember now where I read that Herder once exploded peevishly at the constant preoccupation with Spinoza, "If Goethe would only for once pick up some other Latin book than Spinoza!" But this applies not only to Goethe; quite a number of his friends, who later became more or less well-known as poets, paid homage to pantheism in their youth, and this doctrine flourished actively in German art before it attained supremacy among us as a philosophic theory."

“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.”

“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.”
