the
humiliation and confusion of their author, who is sure to be detected.
These are chiefly narrative and historical lies, all intended to do
infinite honor to their author. He is always the hero of his own
romances; he has been in dangers from which nobody but himself ever
escaped; he has seen with his own eyes, whatever other people have heard
or read of: he has had more 'bonnes fortunes' than ever he knew women;
and has ridden more miles post in one day, than ever courier went in two.
He is soon discovered, and as soon becomes the object of universal
contempt and ridicule. Remember, then, as long as you live, that nothing
but strict truth can carry you through the world, with either your
conscience or your honor unwounded. It is not only your duty, but your
interest; as a proof of which you may always observe, that the greatest
fools are the greatest liars. For my own part, I judge of every man's
truth by his degree of understanding.

This letter will, I suppose, find you at Leipsig; where I expect and
require from you attention and accuracy, in both which you have hitherto
been very deficient. Remember that I shall see you in the summer; shall
examine you most narrowly; and will never forget nor forgive those
faults, which it has been in your own power to prevent or cure; and be
assured that I have many eyes upon you at Leipsig, besides Mr. Harte's.
Adieu!

LETTER XV

LONDON, October 2, O. S. 1747

DEAR BOY: By your letter of the 18th past, N. S., I find that you are a
tolerably good landscape painter, and can present the several views of
Switzerland to the curious. I am very glad of it, as it is a proof of
some attention; but I hope you will be as good a portrait painter, which
is a much more noble science. By portraits, you will easily judge, that
I do not mean the outlines and the coloring of the human figure; but the
inside of the heart and mind of man. This science requires more
attention, observation, and penetration, than the other; as indeed it is
infinitely more useful. Search, therefore, with the greatest care, into
the characters of those whom you converse with; endeavor to discover
their predominant passions, their prevailing weaknesses, their vanities,
their follies, and their humors, with all the right and wrong, wise and
silly springs of human actions, which make such inconsistent and
whimsical beings of us rational creatures. A moderate share of
penetration, with great attention, will inf
