"If you find the light of Scripture clearer than the light of reason , you are doubtless right in your own conscience in making your reason yield. For my part, since I plainly confess that I do not understand the Scriptures, though I have spent many years upon them, and since I know that when once I have a firm proof I cannot by any course of thought come to doubt of it, I rest wholly upon that which my understanding commends to me, without any suspicion that I am deceived therein, or that the Scriptures, even though I do not search them, can speak against it. For one truth cannot conflict with another, as I have already clearly shown in my Appendix to the "Principles of Descartes"...But if in any case I did find error in that which I have collected from my natural understanding, I should count it good fortune, since I enjoy life, and endeavour to pass it not in weeping and sighing, but in peace, joy, and cheerfulness, and from time to time climb thereby a step higher. I know, meanwhile , that all things happen by the power and unchangeable decree of the most perfect Being."

“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.”

“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.”
