As the satisfaction found in reading descriptions of distant countries arises from a comparison which every reader naturally makes, between the ideas which he receives from the relation, and those which were familiar to him before; or, in other words, between the countries with which he is acquainted, and that which the author displays to his imagination; so it varies according to the likeness or dissimilitude of the manners of the two nations.  Any custom or law, unheard and unthought of before, strikes us with that surprise which is the effect of novelty; but a practice conformable to our own pleases us, because it flatters our self-love, by showing us that our opinions are approved by the general concurrence of mankind.  Of these two pleasures, the first is more violent, the other more lasting; the first seems to partake more of instinct than reason, and is not easily to be explained, or defined; the latter has its foundation in good sense and reflection, and evidently depends on the same principles with most human passions.

An attentive reader will frequently feel each of these agreeable emotions in the perusal of Du Halde.  He will find a calm, peaceful satisfaction, when he reads the moral precepts and wise instructions of the Chinese sages; he will find that virtue is in every place the same; and will look with new contempt on those wild reasoners, who affirm, that morality is merely ideal, and that the distinctions between good and ill are wholly chimerical.

But he will enjoy all the pleasure that novelty can afford, when he becomes acquainted with the Chinese government and constitution; he will be amazed to find that there is a country where nobility and knowledge are the same, where men advance in rank as they advance in learning, and promotion is the effect of virtuous industry; where no man thinks ignorance a mark of greatness, or laziness the privilege of high birth.

His surprise will be still heightened by the relations he will there meet with, of honest ministers, who, however incredible it may seem, have been seen more than once in that monarchy, and have adventured to admonish the emperours of any deviation from the laws of their country, or any errour in their conduct, that has endangered either their own safety, or the happiness of their people.  He will read of emperours, who, when they have been addressed in this manner, have neither stormed, nor threatened, nor kicked their ministers, nor thought it majestick to be obstinate in the wrong; but have, with a greatness of mind worthy of a Chinese monarch, brought their actions willingly to the test of reason, law, and morality, and scorned to exert their power in defence of that which they could not support by argument.

I must confess my wonder at these relations was very great, and had been much greater, had I not often entertained my imagination with an instance of the like conduct in a prince of England, on an occasion that happened not quite a century ago, and which I shall relate, that so remarkable an example of spirit and firmness in a subject, and of conviction and compliance in a prince, may not be forgotten.  And I hope you will look upon this letter as intended to do honour to my country, and not to serve your interest by promoting your undertaking.
