sensuous nature which, upon
the ground of pure reason and in the jurisdiction of the moral law, are
completely set aside and excluded.

I will explain. Convinced as I am, and precisely because I am convinced,
that the inclination in associating itself to an act of the will offers
no witness to the pure conformity of this act with the duty, I believe
that we are able to infer from this that the moral perfection of man
cannot shine forth except from this very association of his inclination
with his moral conduct. In fact, the destiny of man is not to accomplish
isolated moral acts, but to be a moral being. That which is prescribed
to him does not consist of virtues, but of virtue, and virtue is not
anything else "than an inclination for duty." Whatever, then, in the
objective sense, may be the opposition which separates the acts suggested
by the inclination from those which duty determines, we cannot say it is
the same in the subjective sense; and not only is it permitted to man to
accord duty with pleasure, but he ought to establish between them this
accord, he ought to obey his reason with a sentiment of joy. It is not
to throw it off as a burden, nor to cast it off as a too coarse skin.
No, it is to unite it, by a union the most intimate, with his Ego, with
the most noble part of his being, that a sensuous nature has been
associated in him to his purely spiritual nature. By the fact that
nature has made of him a being both at once reasonable and sensuous, that
is to say, a man, it has prescribed to him the obligation not to separate
that which she has united; not to sacrifice in him the sensuous being,
were it in the most pure manifestations of the divine part; and never to
found the triumph of one over the oppression and the ruin of the other.
It is only when he gathers, so to speak, his entire humanity together,
and his way of thinking in morals becomes the result of the united action
of the two principles, when morality has become to him a second nature,
it is then only that it is secure; for, as far as the mind and the duty
are obliged to employ violence, it is necessary that the instinct shall
have force to resist them. The enemy which only is overturned can rise
up again, but the enemy reconciled is truly vanquished. In the moral
philosophy of Kant the idea of duty is proposed with a harshness enough
to ruffle the Graces, and one which could easily tempt a feeble mind to
seek for moral perfection in the sombre pat
