"Many people who are engaged in the ecological crisis claim to have been inspired by Spinoza. They read some of Spinoza's texts or his comments on those texts. Some even read about Spinoza himself, but this does not mean that they try to find out exactly what Spinoza meant. Why should they? They make use of his image and his texts in their lives. What more could or should Spinoza expect of them? Spinoza does not write about the beauty of wild nature. Perhaps he never talked about it. Not about the coastline of the Netherlands, the storms, the variety of light and darkness, the seabirds. There were people around him, Dutch landscape painters, who appreciated all this. Maybe he did also, but it scarcely influenced what he says in the Ethics."

“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.”

“veritas norma sui et falsi est”

“Ordo et connexio idearum idem est ac ordo et connexio rerum”

“[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.”
