fifth century BC, who is reputed to have been exiled from Athens because of his agnosticism about the existence of the gods, said that "Concerning the gods I cannot know either that they exist or that they do not exist, or what form they might have, for there is much to prevent one's knowing: the obscurity of the subject and the shortness of man's life."Poster, Carol.

Since at least the eighteenth century, various authors have criticized the suitability of theology as an academic discipline. In 1772, Baron d'Holbach labeled theology "a continual insult to human reason" in Le Bon sens.

This mirrored his earlier work The Essence of Christianity (1841), for which he was banned from teaching in Germany, in which he had said that theology was a "web of contradictions and delusions." The American satirist Mark Twain remarked in his essay "The Lowest Animal", originally written in around 1896, but not published until after Twain's death in 1910, that:[Man] is the only animal that loves his neighbor as himself and cuts his throat if his theology isn't straight.
