There are in man from the Lord two capacities by which the human being
is distinguished from the beasts. One capacity is the ability to
understand what is true and what is good. It is called rationality,
and is a capacity of his understanding. The other capacity is the
ability to do the true and the good. It is called freedom, and is a
power of the will. By virtue of his rationality, man can think what he
pleases, as well against God as with Him, and with his neighbor or
against his neighbor. He can also will and do what he thinks; and when
he sees evil and fears punishment, by virtue of freedom he can refrain
from doing. By these two capacities man is man and is distinguished
from the beasts. Man has these twin powers from the Lord, and they are
from Him every moment; nor are they ever taken away, for if they were,
man's humanity would perish. The Lord is in these two powers with
every man, with the evil as well as the good. They are His
abiding-place in the race. Thence it is that every human being, evil
as well as good, lives to eternity.
