“You desire to know something of my Religion. It is the first time I have been questioned upon it: But I do not take your Curiosity amiss, and shall endeavour in a few Words to gratify it... I have, with most of the present Dissenters in England, some Doubts as to his [Jesus'] divinity; tho' it is a question I do not dogmatize upon, having never studied it, and I think it needless to busy myself with it now, when I expect soon an Opportunity of knowing the Truth with less Trouble.[Letter to Ezra Stiles, March 9, 1790]”

“I do not pretend to give such a sum; I only lend it to you. When you shall return to your country with a good character, you cannot fail of getting into some business, that will in time enable you to pay all your debts. In that case, when you meet with another honest man in similar distress, you must pay me by lending this sum to him; enjoining him to discharge the debt by a like operation, when he shall be able, and shall meet with such another opportunity. I hope it may thus go through many hands, before it meets with a knave that will stop its progress. This is a trick of mine for doing a deal of good with a little money.”

“And, lastly (I may as well confess it, since my denial of it will be believed by nobody), perhaps I shall a good deal gratify my own vanity. Indeed, I scarce ever heard or saw the introductory words, "Without vanity I may say," etc., but some vain thing immediately followed. Most people dislike vanity in others, whatever share they have of it themselves; but I give it fair quarter wherever I meet with it, being persuaded that it is often productive of good to the possessor, and to others that are within his sphere of action; and therefore, in many cases, it would not be altogether absurd if a man were to thank God for is vanity among the other comforts of life.”

“But on the whole, though I never arrived at the perfection I had been so ambitious of obtaining, but fell far short of it, yet I was, by the endeavour, a better and happier man than I otherwise should have been had I not attempted it; as those who aim at perfect writing by imitating the engraved copies, their hand is mended by the endevour, and is tolerable while it continues fair and legible”

“My Parents had early given me religious Impressions, and brought me through my Childhood piously in the Dissenting Way. But I was scarce 15 when, after doubting by turns of several Points as I found them disputed in the different Books I read, I began to doubt of Revelation itself. Some Books against Deism fell into my Hands; they were said to be the Substance of Sermons preached at Boyle's Lectures. It happened that they wrought an Effect on me quite contrary to what was intended by them: For the Arguments of the Deists which were quoted to be refuted, appeared to me much Stronger than the Refutations. In short I soon became a thorough Deist.[Part I, p. 45 of autobiography]”

“Finding myself to exist in the world, I believe i shall, in some shape or other, always exist.”

“I advise you to apply to all those whom you know will give something; next, to those whom you are uncertain whether they will give any thing or not, and show them the list of those who have given; and, lastly, do not neglect those who you are sure will give nothing, for in some of them you may be mistaken.”
