By the way, I do desire, and insist, that whenever, from any indisposition, you are not able to write to me upon the fixed days, that Christian shall; and give me a TRUE account how you are. I do not expect from him the Ciceronian epistolary style; but I will content myself with the Swiss simplicity and truth. I hope you extend your acquaintance at Paris, and frequent variety of companies; the only way of knowing the world; every set of company differs in some particulars from another; and a man of business must, in the course of his life, have to do with all sorts. It is a very great advantage to know the languages of the several countries one travels in; and different companies may, in some degree, be considered as different countries; each hath its distinctive language, customs, and manners: know them all, and you will wonder at none. Adieu, child. Take care of your health; there are no pleasures without it. LETTER CLX LONDON, February 20, O. S. 1752. MY DEAR FRIEND: In all systems whatsoever, whether of religion, government, morals, etc., perfection is the object always proposed, though possibly unattainable; hitherto, at least, certainly unattained. However, those who aim carefully at the mark itself, will unquestionably come nearer it, than those who from despair, negligence, or indolence, leave to chance the work of skill. This maxim holds equally true in common life; those who aim at perfection will come infinitely nearer it than those desponding or indolent spirits, who foolishly say to themselves: Nobody is perfect; perfection is unattainable; to attempt it is chimerical; I shall do as well as others; why then should I give myself trouble to be what I never can, and what, according to the common course of things, I need not be, PERFECT?
