Nothing to me is more evident, than that no nation in any manufacture whatever can undersell their neighbours with whom they are at best but equals as to skill and dispatch, and the conveniency for working, more especially when the prime cost of the thing to be manufactured is not in their favour, unless they have provisions, and whatever is relating to their sustenance, cheaper, or else workmen that are either more assiduous, and will remain longer at their work, or be content with a meaner and coarser way of living than those of their neighbours. This is certain, that where numbers are equal, the more laborious people are, and the fewer hands the same quantity of work is performed by, the greater plenty there is in a country of the necessaries for life, the more considerable and the cheaper that country may render its exports. It being granted, then, that abundance of work is to be done, the next thing which I think to be likewise undeniable, is, that the more cheerfully it is done the better, as well for those that perform it, as for the rest of the society. To be happy is to be pleased, and the less notion a man has of a better way of living, the more content he will be with his own; and, on the other hand, the greater a man's knowledge and experience is in the world, the more exquisite the delicacy of his taste, and the more consummate judge he is of things in general, certainly the more difficult it will be to please him. I would not advance any thing that is barbarous or inhuman: but when a man enjoys himself, laughs and sings, and in his gesture and behaviour shows me all the tokens of content and satisfaction, I pronounce him happy, and have nothing to do with his wit or capacity. I never enter into the reasonableness of his mirth, at least I ought not to judge of it by my own standard, and argue from the effect which the thing that makes him merry would have upon me. At that rate, a man that hates cheese must call me fool for loving blue mold. De gustibus non est disputandum is as true in a metaphorical, as it is in the literal sense; and the greater the distance is between people as to their condition, their circumstances and manner of living, the less capable they are of judging of one another's troubles or pleasures.
