rength varies in a bracing
or relaxing air. A strong bodily constitution may resist longer, and
finally be less affected by a deleterious atmosphere than a weak or
diseased frame; and so it is with the mental constitution. Minds
insensibly imbibe the tone of the atmosphere in which they most
frequently dwell; and though natural loftiness of character and natural
conscientiousness may for a very long period resist such influences, it
cannot be expected that inferior natures will be able to do so.

You are then to consider whether the habits of mind and conversation
among those who are the constant associates of the persons you blame
have been such as to cherish or to deaden keen and refined perceptions
of moral excellence and nobility of mind; still further, whether their
own literary tastes have created around them an even more penetrating
atmosphere; whether from the elevated inspirations of appreciated
poetry, from the truthful page of history, or from the stirring
excitements of romantic fiction, their heart and their imagination have
received those lofty lessons for which you judge them responsible,
without knowing whether they have ever received them.

There is still another consideration. While the actions of those who are
not habitually under the control of high principle depend chiefly on the
physical constitution, as they are too often a mere yielding to the
immediate impulse of the senses, their judgment of men and things, on
the contrary, when uninfluenced by _personal_ feeling, depend probably
more on that keen perception of the beautiful which is the natural
instinct of a superior organization. Morality and religion will indeed
supply the place of these lofty _natural_ instincts, by giving habits of
mind which may in time become so burnt in, as it were, that they assume
the form of natural instincts, while they are at once much safer guides
and much stronger checks.

It is surprising that a mere sense of the beautiful will often confer
the clearest perceptions of the real nature of moral excellence. You may
hear the devoted worldling, or the selfish sensualist, giving the
highest and most inspiring lessons of self-renunciation, self-sacrifice,
and devotedness to God. Their lessons, truthful and impressive, because
dictated by a keen and exquisite perception of the beautiful, which ever
harmonizes with the precepts and doctrines of Christianity, have
kindled in many a heart that living flame, which in thei
