with books, and an absolute stranger to men.  Laboring with his matter, he is delivered of it with pangs; he hesitates, stops in his utterance, and always expresses himself inelegantly.  His actions are all ungraceful; so that, with all his merit and knowledge, I would rather converse six hours with the most frivolous tittle-tattle woman who knew something of the world, than with him.  The preposterous notions of a systematical man who does not know the world, tire the patience of a man who does.  It would be endless to correct his mistakes, nor would he take it kindly:  for he has considered everything deliberately, and is very sure that he is in the right.  Impropriety is a characteristic, and a never-failing one, of these people.  Regardless, because ignorant, of customs and manners, they violate them every moment.  They often shock, though they never mean to offend:  never attending either to the general character, or the particular distinguishing circumstances of the people to whom, or before whom they talk; whereas the knowledge of the world teaches one, that the very same things which are exceedingly right and proper in one company, time and place, are exceedingly absurd in others.  In short, a man who has great knowledge, from experience and observation, of the characters, customs, and manners of mankind, is a being as different from, and as superior to, a man of mere book and systematical knowledge, as a well-managed horse is to an ass.  Study, therefore, cultivate, and frequent men and women; not only in their outward, and consequently, guarded, but in their interior, domestic, and consequently less disguised, characters and manners.  Take your notions of things, as by observation and experience you find they really are, and not as you read that they are or should be; for they never are quite what they should be.  For this purpose do not content yourself with general and common acquaintance; but wherever you can, establish yourself, with a kind of domestic familiarity, in good houses.  For instance, go again to Orli, for two or three days, and so at two or three ‘reprises’.  Go and stay two or three days at a time at Versailles, and improve and extend the acquaintance you have there.  Be at home at St. Cloud; and, whenever any private person of fashion invites you to, pass a few days at his country-house, accept of the invitation.  This will necessarily give you a versatility of mind, and a facility to adopt various manners and customs; for everybody desires to please those in whose house they are; and people are only to be pleased in their own way.  Nothing is more engaging than a cheerful and easy conformity to people’s particular manners, habits, and even weaknesses; nothing (to use a vulgar expression) should come amiss to a young fellow.  He should be, for good purposes, what Alcibiades was commonly for bad ones, a Proteus, assuming with ease, and wearing with cheerfulness, any shape.  Heat, cold, luxury, abstinence, gravity, gayety, ceremony,
