Thomas Gordon, Cato's Letter No. 123 — Inquiry concerning Madness… (1723)
“ It is great madness, mixed with presumption, to pretend to have the spirit of God, unless we can shew it by doing works which only God’s spirit can do; that spirit which can do all things, but foolish things. Enthusiasm is doubtless a fever in the head, and, like other fevers, is spreading and infectious; and all the zeal of the enthusiast is only an ambition to propagate his fever.You never knew a madman of any sort, who was not wiser than all mankind, and did not despise his whole race, who were not blessed with the same obliquity of head. ”
