[…] I soon became a thorough Deist. My arguments perverted some others, particularly Collins and Ralph; but, each of them having afterwards wrong’d me greatly without the least compunction, and recollecting Keith’s conduct towards me (who was another freethinker), and my own towards Vernon and Miss Read, which at times gave me great trouble, I began to suspect that this doctrine, tho’ it might be true, was not very useful.
From The Autobiography of Benjamin Franklin (emphasis mine).
Compare William James, one hundred years or so later:
The pragmatic method is primarily a method of settling metaphysical disputes that otherwise might be interminable. Is the world one or many?–fated or free?–material or spiritual?–here are notions either of which may or may not hold good of the world; and disputes over such notions are unending. The pragmatic method in such cases is to try to interpret each notion by tracing its respective practical consequences. What difference would it practically make to anyone if this notion rather than that notion were true? If no practical difference whatever can be traced, then the alternatives mean practically the same thing, and all dispute is idle. Whenever a dispute is serious, we ought to be able to show some practical difference that must follow from one side or the other’s being right.
