It is not enough; but it is necessary that the agent know what he is
doing; know that it is right or wrong; that he will to do it, as such;
and that he be free to do it, or not to do it. Whenever any one of
these three elements--knowledge, consent and liberty--is wanting in the
commission or omission of any act, the deed is not a moral deed; and
the agent, under the circumstances, is not a moral agent.

When God created man, He did not make him simply a being that walks and
talks, sleeps and eats, laughs and cries; He endowed him with the
faculties of intelligence and free will. More than this, He intended
that these faculties should be exercised in all the details of life;
that the intelligence should direct, and the free will approve, every
step taken, every act performed, every deed left undone. Human energy
being thus controlled, all that man does is said to be voluntary and
bears the peculiar stamp of morality, the quality of being good or evil
in the sight of God and worthy of His praise or blame, according as it
squares or not with the Rule of Morality laid down by Him for the
shaping of human life. Of all else He takes no cognizance, since all
else refers to Him not indifferently from the rest of animal creation,
and offers no higher homage than that of instinct and necessity.

When a man in his waking hours does something in which his intelligence
has no share, does it without being aware of what he is doing, he is
said to be in a state of mental aberration, which is only another name
for insanity or folly, whether it be momentary or permanent of its
nature. A human being, in such a condition, stands on the same plane
with the animal, with this difference, that the one is a freak and the
other is not. Morals, good or bad, have no meaning for either.
