“It is only in the CREATION that all the ideas and concepts of the word of God can come together. The Creation speaks a universal language that does not depend on any human speech or language. It is an eternal 'original copy' that all men can read. It cannot be faked or counterfeited. It cannot be lost or changed. It cannot be kept secret. It does not depend on man deciding whether to publish it or not. It publishes itself from one end of the earth to the other. It preaches to all the nations, and all the worlds. This natural word of God reveals to us all that man needs to know of God.”

“Ignorance is of a peculiar nature; once dispelled, it is impossible to reestablish it. It is not originally a thing of itself, but is only the absence of knowledge; and though man may be kept ignorant, he cannot be made ignorant.”

“Man cannot make principles, he can only discover them.”

“If men will permit themselves to think, as rational beings ought to think, nothing can appear more ridiculous and absurd, exclusive of all moral reflections, than to be at the expence of building navies, filling them with men, and then hauling them into the ocean, to try which can sink each other fastester. Peace, which costs nothing, is attended with infintely more advantage than any victory with all its expence. But this, though it best answers the purpose of Nations, does not that of Court Governments, whose habited policy is pretence for taxation, places, and offices.”

“(To the newly graduated)There never did, there never will, and there never can exist a parliament, or any description of men, or any generation of men, in any country, possessed of the right or the power of binding and controlling posterity to the "end of time", or of commanding for ever how the world shall be governed, or who shall govern it; and therefore all such clauses, acts or declarations, by which the makers of them attempt to do what they have neither the right nor the power to do, nor the power to execute, are in themselves null and void. Every age and generation must be as free to act for itself, in all cases, as the ages and generations which preceded it...Man has no property in man; neither has any generation a property in the generations which are to follow.”

“The Almighty Lecturer, by displaying the principles of science in the structure of the universe, has invited man to study and to imitation. It is as if He has said to the inhabitants of this globe that we call ours, "I have made an earth for man to dwell upon, and I have rendered the starry heavens visible, to teach him science and the arts. He can now provide for his own comfort, and learn from my munificence to all to be kind to each other.”

“It is only by the exercise of reason that man can discover God. Take away that reason, and he would be incapable of understanding anything; and, in this case, it would be just as consistent to read even the book called the Bible to a horse as to a man. How, then, is it that those people pretend to reject reason?”
