If Franklin is not mistaken, his career as a lover of his species can be traced back to a very early circumstance. In one of his letters, in his old age, to Samuel Mather, the descendant of Increase and Cotton Mather, he states that a mutilated copy of Cotton Mather's _Essays to do Good_, which fell in his way when he was a boy, had influenced his conduct through life, and that, if he had been a useful citizen, the public was indebted for the fact to this book. "I have always set a greater value on the character of a _doer of good_, than on any other kind of reputation," he remarks in the letter. "The noblest question in the world," said Poor Richard, "is what good may I do in it." But, no matter how or when the chance seed was sown, it fell upon ground eager to receive it. It was an observation of Franklin that the quantity of good that may be done by one man, if he will make a business of doing good, is prodigious. The saying in its various forms presupposed the sacrifice of all studies, amusements and avocations. No such self-immolation, it is needless to affirm, marked his versatile and happy career, yet rarely has any single person, whose attention has been engaged by other urgent business besides that of mankind, ever furnished such a pointed example of the truth of the observation. The first project of a public nature organized by him was the Junto, a project of which he received the hint from the Neighborhood Benefit Societies, established by Cotton Mather, who, it would be an egregious error to suppose, did nothing in his life but hound hapless wretches to death for witchcraft. The Junto founded by Franklin, when he was a journeyman printer, about twenty-one years of age, was primarily an association for mutual improvement. It met every Friday evening, and its rules, which were drafted by him, required every member in turn to produce one or more queries on some point of morals, politics or natural philosophy, to be discussed by its members, and once every three months to produce and read an essay of his own writing on any subject he pleased. Under the regulations, the debates were to be conducted with a presiding officer in the chair, and in the sincere spirit of inquiry after truth without fondness for dispute or desire for victory. Dogmatism and direct contradiction were made contraband, and prohibited under small pecuniary penalties. With a few rough strokes Franklin etches to the life in the _Autobiography_ all the first members of the association. We linger just now only on his portrait of Thomas Godfrey, "a self-taught mathematician, great in his way, and afterward inventor of what is now called Hadley's Quadrant. But he knew little out of his way, and was not a pleasing companion; as, like most great mathematicians I have met with, he expected universal precision in everything said, or was forever denying or distinguishing upon trifles, to the disturbance of all conversation.
