"Spinoza did not envision secular Judaism. To be a secular or assimilated Jew is, in his view, nonsense. It is to be a nonsectarian sectarian. For him, Judaism without an observance of its textually and historically defined tenets, laws, and ceremonies would be a masquerade. Of course, Spinoza had great contempt for traditional sectarian religions, and Judaism in particular. And he did argue that Jewish law is no longer binding on contemporary Jews. Perhaps in this sense he unwittingly opened the door for a secular or even Reform Judaism. But he also had a very strict understanding of what was to count as Judaism. Spinoza may have been a religious reformer, but what he envisioned was not reform within Judaism. Rather, what he had in mind was a universal rational religion that eschewed meaningless, superstitious rituals and focused instead on a few simple moral principles, above all, to love one's neighbor as oneself."

“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.”
