We know not how far we ought to trust our vulgar methods of reasoning in such a subject; since, even in common life, and in that province which is peculiarly appropriated to them, we cannot account for them, and are entirely guided by a kind of instinct or necessity in employing them.
All sceptics pretend, that, if reason be considered in an abstract view, it furnishes invincible arguments against itself; and that we could never retain any conviction or assurance, on any subject, were not the sceptical reasonings so refined and subtle, that they are not able to counterpoise the more solid and more natural arguments derived from the senses and experience.

But it is evident, whenever our arguments lose this advantage, and run wide of common life, that the most refined scepticism comes to be upon a footing with them, and is able to oppose and counterbalance them.

The one has no more weight than the other.

The mind must remain in suspense between them; and it is that very suspense or balance, which is the triumph of scepticism.
But I observe, says CLEANTHES, with regard to you, PHILO, and all speculative sceptics, that your doctrine and practice are as much at variance in the most abstruse points of theory as in the conduct of common life.

Wherever evidence discovers itself, you adhere to it, notwithstanding your pretended scepticism; and I can observe, too, some of your sect to be as decisive as those who make greater professions of certainty and assurance.
