The better to perform what I have undertaken, I shall previously examine into the reality of the pulchrum et honestum, the to kalon that the ancients have talked of so much: the meaning of this is to discuss, whether there be a real worth and excellency in things, a pre-eminence of one above another; which every body will always agree to that well understands them; or, that there are few things, if any, that have the same esteem paid them, and which the same judgment is passed upon in all countries and all ages. When we first set out in quest of this intrinsic worth, and find one thing better than another, and a third better than that, and so on, we begin to entertain great hopes of success; but when we meet with several things that are all very good or all very bad, we are puzzled, and agree not always with ourselves, much less with others. There are different faults as well as beauties, that as modes and fashions alter and men vary in their tastes and humours, will be differently admired or disapproved of. Judges of painting will never disagree in opinion, when a fine picture is compared to the daubing of a novice; but how strangely have they differed as to the works of eminent masters! There are parties among connoisseurs; and few of them agree in their esteem as to ages and countries; and the best pictures bear not always the best prices: a noted original will be ever worth more than any copy that can be made of it by an unknown hand, though it should be better. The value that is set on paintings depends not only on the name of the master, and the time of his age he drew them in, but likewise in a great measure on the scarcity of his works; but, what is still more unreasonable, the quality of the persons in whose possession they are, as well as the length of time they have been in great families; and if the Cartons, now at Hampton-Court, were done by a less famous hand than that of Raphael, and had a private person for their owner, who would be forced to sell them, they would never yield the tenth part of the money which, with all their gross faults, they are now esteemed to be worth.
