Phylosophy which is the result of Reason, is the first, the original Revelation of The Creator to his Creature, Man. When this Revelation is clear and certain, by Intuition or necessary Induction, no subsequent Revelation supported by Prophecies or Miracles can supercede it. Phylosophy is not only the love of Wisdom, but the Science of the Universe and its Cause.

John Adams, letter to Thomas Jefferson, December 25, 1813

It’s getting too much. Lately it’s not just the creationists. We also hear from flat-earthers (geocentrists), and probably half the people in the U.S. think the movie Noah was based on a true story. Several of our Founding Fathers knew enough to trust science.

That I have no Friendship for Franklin I avow. That I am incapable of having any with a Man of his moral Sentiments, I avow. As Far as cruel Fate shall compell me to act with him in publick affairs, I shall treat him with decency and perfect Impartiallity, further than that I can feel for him no other sentiments than Contempt or Abhorrence. In my Soul I believe of him all the Burke says of shelburne. Yet to undertake to lay before the public all the Reasons I have for believing so would do more hurt at present than his Neck and mine too are both worth, and therefore I have Said and shall say as little about it, as is consistent with my Honour.

John Adams, letter to Edmund Jennings, July 20, 1782

The feeling was mutual.

Doctor Franklin, a sagacious observer of human nature, drew this portrait of Mr. Adams: - “He is always honest, sometimes great, but often mad.” I subscribe to the justness of this picture, adding as to the first trait of it this qualification - “as far as a man excessively vain and jealous, and ignobly attached to place can be.”

Alexander Hamilton, letter to Charles Carroll of Carrollton, July 1, 1800

That there is such a Person as The Devil is no part of my Faith, nor that of many other Christians; nor am I sure that it was the belief of any of the christian Writers. Neither do I believe the doctrine of demoniacal possessions, whether it was believed by the sacred Writers or not; and yet my unbelief in these Articles does not affect my faith in the great facts of which the Evangelists were eye and ear witnesses.

John Adams, letter to Thomas Jefferson, March 3, 1814

The Experience of all my Life has proved to me, that the Memory of Malice is faithfull, and more, it continually adds to its Stock; while that of Kindness and Friendship is not only frail but treacherous.

John Adams, from his autobiography, begun in 1802

The Church of Rome has made it an Article of Faith that no man can be saved out of their Church, and all other religious Sects approach to this dreadfull opinion in proportion to their Ignorance, and the Influence of ignorant or wicked Priests.

John Adams, from his diary, February 16, 1756

The National Fast, recommended by me turned me out of office. It was connected with the general assembly of the Presbyterian Church, which I had no concern in. That assembly has allarmed and alienated Quakers, Anabaptists, Mennonists, Moravians, Swedenbogians, Methodists, Catholicks, protestant Episcopalians, Arians, Socinians, Armenians, & & &, Atheists and Deists might be added. A general Suspicion prevailed that the Presbyterian Church was ambitious and aimed at an Establishment of a National Church. I was represented as a Presbyterian and at the head of this political and ecclesiastical project. The secret whisper ran through them “Let us have Jefferson, Madison, Burr, any body, whether they be Philosophers, Deists, or even Atheists, rather than a Presbyterian President.” This principle is at the bottom of the unpopularity of national Fasts and Thanksgivings. Nothing is more dreaded than the National Government meddling with Religion.

John Adams, letter to Benjamin Rush, June 12, 1812

There is in human Nature a solid, unchangeable and eternal Foundation of Religion. There is also a germ of superstition, seemingly a fungous growth or a spurious sprout, which the grossest Blockheads and most atrocious Villains are able to cultivate into Systems and Sects to deceive millions and cheat and pillage hundreds and thousands of their fellow Creatures.

John Adams, letter to John Quincy Adams, May 10, 1816

That humans have an innate tendency to believe in a religion is something I can believe. I just personally think it’s part of the superstition, which is much more than a germ.

The Bible itself has not authority sufficient in these days to reconcile negro slavery to reason, justice & humanity. … I shudder when I think of the calamities which slavery is likely to produce in this country. You would think me mad if I were to describe my anticipations. If the gangrene is not stopped, I can see nothing but insurrections of the blacks against the whites and massacres by the whites in their turn of the blacks.

John Adams, letter to Louisa Catherine Adams, January 13, 1820

The poor people, it is true, have been much less successful than the great. They have seldom found either leisure or opportunity to form an union and exert their strength - ignorant as they were of arts and letters, they have seldom been able to frame and support a regular opposition. This, however, has been known, by the great, to be the temper of mankind, and they have accordingly laboured, in all ages, to wrest from the populace, as they are contemptuously called, the knowledge of their rights and wrongs, and the power to assert the former or redress the latter.

John Adams, A Dissertation on the Canon and Feudal Law No. 1, August 12, 1765

And the great (the rich) in Michigan, named DeVos, labour against labor to this day. Unions exist to protect workers and their rights. The existence of a union does not mean you have thugs.
