"Spinoza is unsuitable as a patron philosopher of any contemporary movement, including the environmental and ecological. His system and his thinking in general are overwhelmingly complicated, and his terminology in central areas utterly foreign to contemporary jargons. But this does not exclude the possibility that he is an inexhaustible source of inspiration for those who look for a philosophy explicating deep attitudes and assumptions within certain parts of the international ecological and environmental movement. Admirers of Spinoza quite naturally tend to interpret him so as to minimize the conflicts between his and their thought. The result is a variety of representations of Spinoza. But if the intention is to provide more or less free reconstructions, well and good. And this is what is relevant, as I see it, in relation to what is sometimes called the "deep ecological movement" and the "green philosophy and ecopolitics."

“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.”
