When I went home to my family in May, 1770, from the town meeting in Boston, which was the first I had ever attended, and where I had been chosen in … - John Adams

I have accepted a seat in the House of Representatives, and thereby have consented to my own ruin, to your ruin, and to the ruin of our children. I give you this warning that you may prepare your mind for your fate.

There is nothing in which mankind have been more unanimous [founding nations upon superstition]; 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... [T]he detail of the formation of the American governments... 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... it will for ever be acknowledged that these governments were contrived merely by the use of reason and the senses... 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.

The moment the idea is admitted into society, that property is not as sacred as the law of God, and that there is not a force of law and public justice to protect it, anarchy and tyranny commence. If "Thou shall not covet," and "Thou shall not steal," are not commandments of Heaven, they must be made inviolable precepts in every society, before it can be civilized or made free.

I do not say that democracy has been more pernicious on the whole, and in the long run, than monarchy or aristocracy. Democracy has never been and never can be so durable as aristocracy or monarchy; but while it lasts, it is more bloody than either. … Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There never was a democracy yet that did not commit suicide. It is in vain to say that democracy is less vain, less proud, less selfish, less ambitious, or less avaricious than aristocracy or monarchy. It is not true, in fact, and nowhere appears in history. Those passions are the same in all men, under all forms of simple government, and when unchecked, produce the same effects of fraud, violence, and cruelty. When clear prospects are opened before vanity, pride, avarice, or ambition, for their easy gratification, it is hard for the most considerate philosophers and the most conscientious moralists to resist the temptation. Individuals have conquered themselves. Nations and large bodies of men, never.
