To philosopher and historian the madness and imbecile wickedness of mankind ought to appear ordinary events.

All knowledge degenerates into probability.

I know with certainty, that [an honest man] is not to put his hand into the fire, and hold it there, till it be consumed: And thisevent, I think I can foretell with the same assurance, as that, if he throw himself out at the window, and meet with no obstruction, he will not remain a moment suspended in the air.

There is an universal tendency among mankind to conceive all beings like themselves, and to transfer to every object, those qualities, with which they are familiarly acquainted, and of which they are intimately conscious. We find human faces in the moon, armies in the clouds; and by a natural propensity, if not corrected by experience and reflection, ascribe malice or good-will to every thing, that hurts or pleases us.

If refined sense, and exalted sense, be not so useful as common sense, their rarity, their novelty, and the nobleness of their objects, make some compensation, and render them the admiration of mankind.

Praise never gives us much pleasure unless it concur with our own opinion, and extol us for those qualities in which we chiefly excel.

There is, indeed a more mitigated scepticism or academical philosophy, which may be both durable and useful, and which may, in part, be the result of this Pyrrhonism, or excessive scepticism, when its undistinguished doubts are corrected by common sense and reflection.
