"...This awareness has become a kind of pre-Freudian self-analysis for me; Spinoza helps me to see myself and my surroundings objectively. This can make life bearable even throughout the experience of suffering; the teachings presented in the Ethics allow one to preceive the world as a manageable place. Freud himself once wrote in a letter to Bickel, 'I admit my dependence on Spinoza's teachings.' Conversely, Spinoza admits, foreshadowing Freudian analysis, that we cannot be in complete control over our emotions. The ability to create emotional balance, though, is dependent upon the intellectual awareness of the problem. In this way Spinoza demands the integration of all human aspects in order to attain true freedom."

“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.”
