"The first person ever to have posed the problem of reading, and in consequence, of writing, was Spinoza, and he was also the first in the world to have proposed both a theory of history and a philosophy of the opacity of the immediate. With him, for the first time ever, a man linked together in this way the essence of reading and the essence of history in a theory of the difference between the imaginary and the true. This explains to us why Marx could not possibly have become Marx except by founding a theory of history and a philosophy of the historical distinction between ideology and science, and why in the last analysis this foundation was consummated in the dissipation of the religious myth of reading."

“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.”

“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.”
