You propose then, Philo, said Cleanthes, to erect religious faith on philosophical scepticism; and you think, that if certainty or evidence be expelled from every other subject of inquiry, it will all retire to these theological doctrines, and there acquire a superior force and authority. Whether your scepticism be as absolute and sincere as you pretend, we shall learn by and by, when the company breaks up: We shall then see, whether you go out at the door or the window; and whether you really doubt if your body has gravity, or can be injured by its fall; according to popular opinion, derived from our fallacious senses, and more fallacious experience. And this consideration, Demea, may, I think, fairly serve to abate our ill-will to this humorous sect of the sceptics. If they be thoroughly in earnest, they will not long trouble the world with their doubts, cavils, and disputes: If they be only in jest, they are, perhaps, bad railers; but can never be very dangerous, either to the state, to philosophy, or to religion. In reality, Philo, continued he, it seems certain, that though a man, in a flush of humour, after intense reflection on the many contradictions and imperfections of human reason, may entirely renounce all belief and opinion, it is impossible for him to persevere in this total scepticism, or make it appear in his conduct for a few hours. External objects press in upon him; passions solicit him; his philosophical melancholy dissipates; and even the utmost violence upon his own temper will not be able, during any time, to preserve the poor appearance of scepticism. And for what reason impose on himself such a violence? This is a point in which it will be impossible for him ever to satisfy himself, consistently with his sceptical principles. So that, upon the whole, nothing could be more ridiculous than the principles of the ancient Pyrrhonians; if in reality they endeavoured, as is pretended, to extend, throughout, the same scepticism which they had learned from the declamations of their schools, and which they ought to have confined to them.
