e in fact, or only logically separable
(like concave and convex), is immaterial to the present enquiry. Of
the irrational, the lowest portion is the Vegetative [Greek:
phytikon], which seems most active in sleep; a state where bad men and
good are on a par, and which is incapable of any human excellence. The
next portion is the Appetitive [Greek: epithymaetikon], which is not
thus incapable. It partakes of reason, yet it includes something
conflicting with reason. These conflicting tendencies are usually
modifiable by reason, and may become in the temperate man completely
obedient to reason. There remains Reason--the highest and sovereign
portion of the soul. Human excellence [Greek: aretae] or virtue, is
either of the Appetitive part,--moral [Greek: aethikae] virtue; or of
the Reason--intellectual [Greek: dianoaetikae] virtue. Liberality and
temperance are Moral virtues; philosophy, intelligence, and wisdom,
Intellectual (XIII.).
Such is an outline of the First Book, having for its subject the Chief
Good, the Supreme End of man.
Book Second embraces the consideration of points relative to the Moral
Virtues; it also commences Aristotle's celebrated definition and
classification of the virtues or excellencies.
Whereas intellectual excellence is chiefly generated and improved by
teaching, moral excellence is a result of habit [Greek: ethos]; whence
its name (Ethical). Hence we may see that moral excellence is no
inherent part of our nature: if it were, it could not be reversed by
habit--any more than a stone can acquire from any number of
repetitions the habit of moving upward, or fire the habit of moving
downward. These moral excellencies are neither a part of our nature,
nor yet contrary to our nature: we are by nature fitted to take them
on, but they are brought to consummation through habit. It is not with
them, as with our senses, where nature first gives us the power to see
and hear, and where we afterwards exercise that power. Moral virtues
are acquired only by practice. We learn to build or to play the harp,
by building or playing the harp: so too we become just or courageous,
by a course of just or courageous acts. This is attested by all
lawgivers in their respective cities; all of them shape the characters
of their respective citizens, by enforcing habitual practice. Some do
it well; others ill; according to the practice, so will be the
resulting character; as he that is practised in building badly, will
