“I do like men who come out frankly and own that they are not gods.”

Dissi, a quelle parole, che gli uomini che volevan fare a lor modo, bisognava che si facessino un mondo a lor modo, perché in questo non si usava cosí.

Letter to Evert Augustus Duyckinck (3 March 1849); published in The Letters of Herman Melville (1960) edited by Merrell R. Davis and William H. Gilman, p. 78; a portion of this is sometimes modernized in two ways:
Context: I do not oscillate in Emerson's rainbow, but prefer rather to hang myself in mine own halter than swing in any other man's swing. Yet I think Emerson is more than a brilliant fellow. Be his stuff begged, borrowed, or stolen, or of his own domestic manufacture he is an uncommon man. Swear he is a humbug — then is he no common humbug. Lay it down that had not Sir Thomas Browne lived, Emerson would not have mystified — I will answer, that had not Old Zack's father begot him, old Zack would never have been the hero of Palo Alto. The truth is that we are all sons, grandsons, or nephews or great-nephews of those who go before us. No one is his own sire. — I was very agreeably disappointed in Mr Emerson. I had heard of him as full of transcendentalisms, myths & oracular gibberish; I had only glanced at a book of his once in Putnam's store — that was all I knew of him, till I heard him lecture. — To my surprise, I found him quite intelligible, tho' to say truth, they told me that that night he was unusually plain. — Now, there is a something about every man elevated above mediocrity, which is, for the most part, instinctuly perceptible. This I see in Mr Emerson. And, frankly, for the sake of the argument, let us call him a fool; — then had I rather be a fool than a wise man. —I love all men who dive. Any fish can swim near the surface, but it takes a great whale to go down stairs five miles or more; & if he don't attain the bottom, why, all the lead in Galena can't fashion the plumet that will. I'm not talking of Mr Emerson now — but of the whole corps of thought-divers, that have been diving & coming up again with bloodshot eyes since the world began.
I could readily see in Emerson, notwithstanding his merit, a gaping flaw. It was, the insinuation, that had he lived in those days when the world was made, he might have offered some valuable suggestions. These men are all cracked right across the brow. And never will the pullers-down be able to cope with the builders-up. And this pulling down is easy enough — a keg of powder blew up Block's Monument — but the man who applied the match, could not, alone, build such a pile to save his soul from the shark-maw of the Devil. But enough of this Plato who talks thro' his nose.

As quoted in Art and the Message of the Church (1961) by Walter Ludwig Nathan, p. 120.

The Nature, Importance and Liberties of Belief (1873)
Context: Now, evidence to a man is that which convinces his mind. It varies with different men. An argument to a man who cannot reason is no evidence. Facts are no evidence to a man who cannot perceive them. A sentimental appeal is evidence to a man whose very nature moves by emotion, though it may not be to his neighbor.
So then, when men come to the investigation of truth, they are responsible, first, for research, for honesty therein, for being diligent, and for attempting to cleanse their minds from all bias of selfishness and pride. They are responsible for sincerity and faithfulness in the investigation of truth. And when they go beyond that to the use of their faculties, the combination of those faculties will determine very largely, not, perhaps, the generic nature of truth, but specific developments of it. And as long as the world stands there will be men who will hold that God is a God of infinite love and sympathy and. goodness with a residunm of justice; and there will be men who will believe that God is a God of justice with a residunm of love and sympathy and goodness; and each will follow the law of his own mind. As a magnet, drawn through a vessel containing sand and particles of iron, attracts the particles of iron but does not attract the sand; so the faculties of a man's mind appropriate certain facts and reject others. What is evidence to a man will depend upon those of his faculties whk at work upon the things which are presented as evidence.

As quoted in On Nature and Grace, Ch. 77, by Augustine of Hippo, as translated by Peter Holmes, Robert Ernest Wallis and Benjamin B Warfield in A Select Library of the Nicene and Post-Nicene Fathers of the Christian Church, Vol. 5 (1887), edited by Philip Schaf, p. 148
The quote above is actually from a Pythagorean philosopher. Pelagius attributed the quote to Pope Sixtus, and Augustine followed his lead until he discovered the error. Augustine himself corrects the source of the quote in the "Retractations" section of his book.
