In his "Autobiography" Franklin wrote that as a young man ""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."" Like some other deists, Franklin believed that, "The Deity sometimes interferes by his particular Providence, and sets aside the Events which would otherwise have been produc'd in the Course of Nature, or by the Free Agency of Man," and stated at the Constitutional Convention that "the longer I live, the more convincing proofs I see of this truth— that God governs in the affairs of men."
