While I was sitting down to write you a friendly Letter I had the pleasure of receiving your Favor of the 22 Instant by the Post. My Intention was to congratulate you and your Brethren the Selectmen, upon the precipitate Flight of the British Army & its Adherents from the Town of Boston, and to urge on you the Necessity of fortifying the Harbour so as that the Enemies Ships might never approach it hereafter. Our grateful Acknowledgments are due to the Supreme Being who has not been regardless of the multiplied Oppressions which the Inhabitants of that City have sufferd under the Hand of an execrable Tyrant. Their Magnanimity & Perseverance during the severe Conflict has afforded a great Example to the World, and will be recorded by the impartial Historian to their immortal Honor. They are now restored to their Habitations & Privileges; and as they are purgd of those Wretches a Part of whose Policy has been to corrupt the Morals of the People, I am perswaded they will improve the happy opportunity of reestablishing ancient Principles and Purity of Manners--I mention this in the first place because I fully agree in Opinion with a very celebrated Author, that, "Freedom or Slavery will prevail in a (City or) Country according as the Disposition & Manners of the People render them fit for the one or the other"; and I have long been convincd that our Enemies have made it an Object, to eradicate from the Minds of the People in general a Sense of true Religion & Virtue, in hopes thereby the more easily to carry their Point of enslaving them. Indeed my Friend, this is a Subject so important in my Mind, that I know not how to leave it. Revelation assures us that "Righteousness exalteth a Nation"- -Communities are dealt with in this World by the wise and just Ruler of the Universe. He rewards or punishes them according to their general Character. The diminution of publick Virtue is usually attended with that of publick Happiness, and the publick Liberty will not long survive the total Extinction of Morals. "The Roman Empire, says the Historian, MUST have sunk, though the Goths had not invaded it. Why? Because the Roman Virtue was sunk." Could I be assured that America would remain virtuous, I would venture to defy the utmost Efforts of Enemies to subjugate her. You will allow me to remind you, that the Morals of that City which has born so great a Share in the American Contest, depend much upon the Vigilance of the respectable Body of Magistrates of which you are a Member.
