I want to know your determination, where you intend to (if I may use that expression) while away your time till the last week in June, when we are to meet at Spa; I continue rather in the opinion which I mentioned to you formerly, in favor of The Hague; but however, I have not the least objection to Dresden, or to any other place that you may like better. If you prefer the Dutch scheme, you take Treves and Coblentz in your way, as also Dusseldorp: all which places I think you have not yet seen. At Manheim you may certainly get good letters of recommendation to the courts of the two Electors of Treves and Cologne, whom you are yet unacquainted with; and I should wish you to know them all; for, as I have often told you, ‘olim haec meminisse juvabit’. There is an utility in having seen what other people have seen, and there is a justifiable pride in having seen what others have not seen. In the former case, you are equal to others; in the latter, superior. As your stay abroad will not now be very long, pray, while it lasts, see everything and everybody you can, and see them well, with care and attention. It is not to be conceived of what advantage it is to anybody to have seen more things, people, and countries, than other people in general have; it gives them a credit, makes them referred to, and they become the objects of the attention of the company. They are not out in any part of polite conversation; they are acquainted with all the places, customs, courts, and families that are likely to be mentioned; they are, as Monsieur de Maupertuis justly observes, ’de tous les pays, comme les savans, sont de tous les tems’. You have, fortunately, both those advantages: the only remaining point is ‘de savoir les faire valoir’, for without that one may as well not have them. Remember that very true maxim of La Bruyere’s, ‘Qu’on ne vaut dans se monde que ce qu’on veut valoir’. The knowledge of the world will teach you to what degree you ought to show ’que vous valez’. One must by no means, on one hand, be indifferent about it; as, on the other, one must not display it with affectation, and in an overbearing manner, but, of the two, it is better to show too much than too little. Adieu.
