nature, our moral opinions are in a large measure amenable to reason. Now
in every society the traditional notions as to what is good or bad,
obligatory or indifferent, are commonly accepted by the majority of
people without further reflection. By tracing them to their source it
will be found that not a few of these notions have their origin in
sentimental likings and antipathies, to which a scrutinizing and
enlightened judge can attach little importance; whilst, on the other
hand, he must account blamable many an act and omission which public
opinion, out of thoughtlessness, treats with indifference." Vol. I, pp.
2-3. See also his appeals to reason where it is a question of the
attitude of the community toward legal responsibility on the part of the
young, toward drunkenness, and toward the heedless production of
offspring doomed to misery and disease, pp. 269 and 310.]

An appeal, thus, from the actual to the ideal appears to be possible.
And, since the natural man, unenlightened and unreflective, is not more
inclined to show himself to be a reasonable being in the sphere of morals
than elsewhere, it seems that there is no little need of ethical science.
Its aim is to bring about the needed enlightenment. Its value can only be
logically denied by those who maintain seriously that it is easy to know
what it is right to do. Do men really hold this, if they are thoughtful?
