I shall never assent to so harsh an opinion as that of a celebrated writer [L'Arte de penser], who says, that the Sceptics are not a sect of philosophers: They are only a sect of liars. I may, however, affirm (I hope without offence), that they are a sect of jesters or raillers. But for my part, whenever I find myself disposed to mirth and amusement, I shall certainly choose my entertainment of a less perplexing and abstruse nature. A comedy, a novel, or at most a history, seems a more natural recreation than such metaphysical subtleties and abstractions. In vain would the sceptic make a distinction between science and common life, or between one science and another. The arguments employed in all, if just, are of a similar nature, and contain the same force and evidence. Or if there be any difference among them, the advantage lies entirely on the side of theology and natural religion. Many principles of mechanics are founded on very abstruse reasoning; yet no man who has any pretensions to science, even no speculative sceptic, pretends to entertain the least doubt with regard to them. The COPERNICAN system contains the most surprising paradox, and the most contrary to our natural conceptions, to appearances, and to our very senses: yet even monks and inquisitors are now constrained to withdraw their opposition to it. And shall PHILO, a man of so liberal a genius and extensive knowledge, entertain any general undistinguished scruples with regard to the religious hypothesis, which is founded on the simplest and most obvious arguments, and, unless it meets with artificial obstacles, has such easy access and admission into the mind of man?
