g. But this tempering and moderating the sensuous impulsion ought
not to be the effect of physical impotence or of a blunting of
sensations, which is always a matter for contempt. It must be a free
act, an activity of the person, which by its moral intensity moderates
the sensuous intensity, and by the sway of impressions takes from them in
depth what it gives them in surface or breadth. The character must place
limits to temperament, for the senses have only the right to lose
elements if it be to the advantage of the mind. In its turn, the
tempering of the formal impulsion must not result from moral impotence,
from a relaxation of thought and will, which would degrade humanity. It
is necessary that the glorious source of this second tempering should be
the fulness of sensations; it is necessary that sensuousness itself
should defend its field with a victorious arm and resist the violence
that the invading activity of the mind would do to it. In a word, it is
necessary that the material impulsion should be contained in the limits
of propriety by personality, and the formal impulsion by receptivity or
nature.

LETTER XIV.

We have been brought to the idea of such a correlation between the two
impulsions that the action of the one establishes and limits at the same
time the action of the other, and that each of them, taken in isolation,
does arrive at its highest manifestation just because the other is
active.

No doubt this correlation of the two impulsions is simply a problem
advanced by reason, and which man will only be able to solve in the
perfection of his being. It is in the strictest signification of the
term: the idea of his humanity; accordingly, it is an infinite to which
he can approach nearer and nearer in the course of time, but without ever
reaching it. "He ought not to aim at form to the injury of reality, nor
to reality to the detriment of the form. He must rather seek the
absolute being by means of a determinate being, and the determinate being
by means of an infinite being. He must set the world before him because
he is a person, and he must be a person because he has the world before
him. He must feel because he has a consciousness of himself, and he must
have a consciousness of himself because he feels." It is only in
conformity with this idea that he is a man in the full sense of the word;
but he cannot be convinced of this so long as he gives himself up
exclusively to one of these two imp
