Now as to the matter of lying. You want to be very careful
about lying; otherwise you are nearly sure to get caught.
Once caught, you can ever again be, in the eyes of 【M1】 .
the good and the pure, that you were before. Many a 【M2】 .
young person have injured himself permanently 【M3】 .
through a single clumsy and illfinished lie, the
result of carelessness born to incomplete training. 【M4】 .
Some authorities hold that the young ought to lie at all. 【M5】 .
That, of course, is putting it rather stronger than necessary;
still, while I cannot go quite so far as that, I do maintain,
and I believe I am right, that the young ought to
be temperate to the use of this great art until practice and 【M6】 .
experience shall give them that confidence, elegance, and
precision which alone can make the accomplishment graceful
and profitable. Patience, diligence, painstaking attention to
detail--these are the requirements; these, in the rime, 【M7】 .
will make the student perfect; at these, and upon these only, 【M8】 .
may he rely as the sure foundation for future eminence. Think
what tedious years of study, thought, practice, experience,
went to the equipment of that peerless old master who was
able to impose upon the whole world the lofty and
sounding maxim which "truth is mighty and will prevail" 【M9】 .
--that most majestic compound fracture of fact which any
woman born has yet achieved. Of the history of our race, and
each individual's experience, are sown thick with evidence
that a truth is not hard to kill and what a lie told well is immortal. 【M10】 .
【M1】
