"Well before John Stuart Mill, Spinoza had the acuity to recognize that the unfettered freedom of expression is in the state's own best interest. In this post-9/11 world, there is a temptation to believe that “homeland security” is better secured by the suppression of certain liberties than their free exercise. This includes a tendency by justices to interpret existing laws in restrictive ways and efforts by lawmakers to create new limitations, as well as a willingness among the populace, “for the sake of peace and security,” to acquiesce in this. We seem ready not only to engage in a higher degree of self-censorship, but also to accept a loosening of legal protections against prior restraint , unwarranted surveillance, unreasonable search and seizure, and other intrusive measures. Spinoza, long ago, recognized the danger in such thinking, both for individuals and for the polity at large. He saw that there was no need to make a trade-off between political and social well-being and the freedom of expression; on the contrary, the former depends on the latter."

“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.”
