28. Enough of this. Let us return to the question from which we
digressed. We granted that the desires, pains and pleasures (considered
not only as sentiments, but as passions), originate in the constitution
of the organized and living body. Must the same origin be assigned to
the irascible (power)? Were this so, we would have several questions to
ask: Does anger belong to the entire organism, or only to a particular
organ, such as the heart when so disposed, or to the bile, as long as
it is part of a living body? Is anger different from the principle
which gives the body a trace of the soul, or is it an individual power,
which depends on no other power, whether irascible or sensitive?
