Nothing can be more unphilosophical than to be positive or dogmatical on any subject; and even if excessive scepticism could be maintained it would not be more destructive to all just reasoning and inquiry. When men are the most sure and arrogant, they are commonly the most mistaken, and have there given reins to passion, without that proper deliberation and suspense which can alone secure them from the grossest absurdities.

Were a man, whom I know to be honest and opulent, and with whom I live in intimate friendship, to come into my house, where I am surrounded with my servants, I rest assured, that he is not to stab me before he leaves it, in order to rob me of my silver standish; and I no more suspect this event, than the falling of the house itself which is new, and solidly built and founded.--But he may have been seized with a sudden and unknown frenzy.--So may a sudden earthquake arise, and shake and tumble my house about my ears.

..when, in my philosophical disquisitions, I deny a providence and a future state, I undermine not the foundations of society, but advance principles, which they themselves, upon their own topics, if they argue consistently, must allow to be solid and satisfactory.

It is harder to avoid censure than to gain applause.

And indeed nothing but the most determined scepticism, along with a great degree of indolence, can justify this aversion to metaphysics. For if truth be at all within the reach of human capacity, it is certain it must lie very deep and abstruse: and to hope we shall arrive at it without pains, while the greatest geniuses have failed with the utmost pains, must certainly be esteemed sufficiently vain and presumptuous. I pretend to no such advantage in the philosophy I am going to unfold, and would esteem it a strong presumption against it, were it so very easy and obvious.

That the sun shines tomorrow is a judgement that is as true as the contrary judgement.

The life of man is of no greater importance to the universe than that of an oyster.
