The role of reason is not to make us wise but to reveal our ignorance - David Hume

Custom, then, is the great guide of human life. It is that principle alone which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past. Without the influence of custom, we should be entirely ignorant of every matter of fact beyond what is immediately present to the memory and senses. We should never know how to adjust means to ends, or to employ our natural powers in the production of any effect. There would be an end at once of all action, as well as of the chief part of speculation.

That original intelligence, say the MAGIANS, who is the first principle of all things, discovers himself immediately to the mind and understanding alone; but has placed the sun as his image in the visible universe; and when that bright luminary diffuses its beams over the earth and the firmament, it is a faint copy of the glory which resides in the higher heavens. If you would escape the displeasure of this divine being, you must be careful never to set your bare foot upon the ground, nor spit into a fire, nor throw any water upon it, even though it were consuming a whole city. Who can express the perfections of the Almighty? say the Mahometans. Even the noblest of his works, if compared to him, are but dust and rubbish. How much more must human conception fall short of his infinite perfections? His smile and favour renders men for ever happy; and to obtain it for your children, the best method is to cut off from them, while infants, a little bit of skin, about half the breadth of a farthing. Take two bits of cloth, say the Roman catholics, about an inch or an inch and a half square, join them by the corners with two strings or pieces of tape about sixteen inches long, throw this over your head, and make one of the bits of cloth lie upon your breast, and the other upon your back, keeping them next your skin: There is not a better secret for recommending yourself to that infinite Being, who exists from eternity to eternity.

Reasonable men may be allowed to differ where no one can reasonably be positive: Opposite sentiments, even without any decision, afford an agreeable amusement; and if the subject be curious and interesting, the book carries us, in a manner, into company, and unites the two greatest and purest pleasures of human life: study and society.
