“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”

“All the perplexities, confusion, and distress in America arise, not from want of honor or virtue, but from the downright ignorance of the nature of coin, credit, and circulation.”

“Now be it known, That I John Adams, President of the United States of America, having seen and considered the said Treaty do, by and with the advice and consent of the Senate, accept, ratify, and confirm the same, and every clause and article thereof. And to the End that the said Treaty may be observed, and performed with good Faith on the part of the United States, I have ordered the premises to be made public; And I do hereby enjoin and require all persons bearing office civil or military within the United States, and all other citizens or inhabitants thereof, faithfully to observe and fulfill the said Treaty and every clause and article thereof.”

“I almost shudder at the thought of alluding to the most fatal example of the abuses of grief which the history of mankind has preserved - the Cross. Consider what calamities that engine of grief has produced! With the rational respect that is due to it, knavish priests have added prostitutions of it, that fill or might fill the blackest and bloodiest pages of human history.{Letter to Thomas Jefferson, September 3, 1816]”

“The jaws of power are always open to devour, and her arm is always stretched out, if possible, to destroy the freedom of thinking, speaking, and writing.”

“It was the general opinion of ancient nations, that the divinity alone was adequate to the important office of giving laws to men... and modern nations, in the consecrations of kings, and in several superstitious chimeras of divine rights in princes and nobles, are nearly unanimous in preserving remnants of it... Is the jealousy of power, and the envy of superiority, so strong in all men, that no considerations of public or private utility are sufficient to engage their submission to rules for their own happiness? Or is the disposition to imposture so prevalent in men of experience, that their private views of ambition and avarice can be accomplished only by artifice? — … There is nothing in which mankind have been more unanimous; yet nothing can be inferred from it more than this, that the multitude have always been credulous, and the few artful. The United States of America have exhibited, perhaps, the first example of governments erected on the simple principles of nature: and if men are now sufficiently enlightened to disabuse themselves of artifice, imposture, hypocrisy, and superstition, they will consider this event as an era in their history. Although the detail of the formation of the American governments is at present little known or regarded either in Europe or America, it may hereafter become an object of curiosity. It will never be pretended that any persons employed in that service had any interviews with the gods, or were in any degree under the inspiration of heaven, any more than those at work upon ships or houses, or labouring in merchandize or agriculture: it will for ever be acknowledged that these governments were contrived merely by the use of reason and the senses. As Copley painted Chatham, West, Wolf, and Trumbull, Warren and Montgomery; as Dwight, Barlow, Trumbull, and Humphries composed their verse, and Belknap and Ramzay history; as Godfrey invented his quadrant, and Rittenhouse his planetarium; as Boylston practised inoculation, and Franklin electricity; as Paine exposed the mistakes of Raynal, and Jefferson those of Buffon, so unphilosophically borrowed from the Recherches Philosophiques sur les Américains those despicable dreams of de Pauw — neither the people, nor their conventions, committees, or sub-committees, considered legislation in any other light than ordinary arts and sciences, only as of more importance. Called without expectation, and compelled without previous inclination, though undoubtedly at the best period of time both for England and America, to erect suddenly new systems of laws for their future government, they adopted the method of a wise architect, in erecting a new palace for the residence of his sovereign. They determined to consult Vitruvius, Palladio, and all other writers of reputation in the art; to examine the most celebrated buildings, whether they remain entire or in ruins; compare these with the principles of writers; and enquire how far both the theories and models were founded in nature, or created by fancy: and, when this should be done, as far as their circumstances would allow, to adopt the advantages, and reject the inconveniences, of all. Unembarrassed by attachments to noble families, hereditary lines and successions, or any considerations of royal blood, even the pious mystery of holy oil had no more influence than that other of holy water: the people universally were too enlightened to be imposed on by artifice; and their leaders, or more properly followers, were men of too much honour to attempt it. Thirteen governments thus founded on the natural authority of the people alone, without a pretence of miracle or mystery, which are destined to spread over the northern part of that whole quarter of the globe, are a great point gained in favour of the rights of mankind.[Preface to 'A Defence of the Constitutions of the United States of America', 1787]”
