rving the characters of the persons, or the subjects of the
conversation; but are either thinking of some trifle, foreign to the
present purpose, or often not thinking at all; which silly and idle
suspension of thought they would dignify with the name of ABSENCE and
DISTRACTION. They go afterward, it may be, to the play, where they gape
at the company and the lights; but without minding the very thing they
went to, the play.

Pray do you be as attentive to your pleasures as to your studies. In the
latter, observe and reflect upon all you read; and, in the former, be
watchful and attentive to all that you see and hear; and never have it
to say, as a thousand fools do, of things that were said and done before
their faces, that, truly, they did not mind them, because they were
thinking of something else. Why were they thinking of something else? and
if they were, why did they come there? The truth is, that the fools were
thinking of nothing. Remember the 'hoc age,' do what you are about, be
what it will; it is either worth doing well, or not at all. Wherever you
are, have (as the low vulgar expression is) your ears and your eyes about
you. Listen to everything that is said, and see everything that is done.
Observe the looks and countenances of those who speak, which is often a
surer way of discovering the truth than from what they say. But then keep
all those observations to yourself, for your own private use, and rarely
communicate them to others. Observe, without being thought an observer,
for otherwise people will be upon their guard before you.

Consider seriously, and follow carefully, I beseech you, my dear child,
the advice which from time to time I have given, and shall continue to
give you; it is at once the result of my long experience, and the effect
of my tenderness for you. I can have no interest in it but yours. You are
not yet capable of wishing yourself half so well as I wish you; follow
therefore, for a time at least, implicitly, advice which you cannot
suspect, though possibly you may not yet see the particular advantages of
it; but you will one day feel them. Adieu.

LETTER XIX

LONDON, November 6, O. S. 1747

DEAR BOY: Three mails are now due from Holland, so that I have no letter
from you to acknowledge; I write to you, therefore, now, as usual, by way
of flapper, to put you in mind of yourself. Doctor Swift, in his account
of the island of Laputa, describes some philosophers there who were s
