tues, in 'actu primo', as the logicians call it, is not
sufficient; you must have them in 'actu secundo' too; nay, that is not
sufficient neither--you must have the reputation of them also. Your
character in the world must be built upon that solid foundation, or it
will soon fall, and upon your own head. You cannot, therefore, be too
careful, too nice, too scrupulous, in establishing this character at
first, upon which your whole depends. Let no conversation, no example, no
fashion, no 'bon mot', no silly desire of seeming to be above, what most
knaves, and many fools, call prejudices, ever tempt you to avow, excuse,
extenuate, or laugh at the least breach of morality; but show upon all
occasions, and take all occasions to show, a detestation and abhorrence
of it. There, though young, you ought to be strict; and there only, while
young, it becomes you to be strict and severe. But there, too, spare the
persons while you lash the crimes. All this relates, as you easily judge,
to the vices of the heart, such as lying, fraud, envy, malice,
detraction, etc., and I do not extend it to the little frailties of
youth, flowing from high spirits and warm blood. It would ill become you,
at your age, to declaim against them, and sententiously censure a
gallantry, an accidental excess of the table, a frolic, an inadvertency;
no, keep as free from them yourself as you can: but say nothing against
them in others. They certainly mend by time, often by reason; and a man's
worldly character is not affected by them, provided it be pure in all
other respects.

To come now to a point of much less, but yet of very great consequence at
your first setting out. Be extremely upon your guard against vanity, the
common failing of inexperienced youth; but particularly against that kind
of vanity that dubs a man a coxcomb; a character which, once acquired, is
more indelible than that of the priesthood. It is not to be imagined by
how many different ways vanity defeats its own purposes. One man decides
peremptorily upon every subject, betrays his ignorance upon many, and
shows a disgusting presumption upon the rest. Another desires to appear
successful among the women; he hints at the encouragement he has
received, from those of the most distinguished rank and beauty, and
intimates a particular connection with some one; if it is true, it is
ungenerous; if false, it is infamous: but in either case he destroys the
reputation he wants to get. Some flatter
