Indeed, to follow what is not Good as if it was the Good, to let
oneself be misled by its appearance, and by irrational inclinations,
that is the characteristic of a man who in spite of himself is led
whither he does not wish to go. Now does this not really amount to
yielding to a magic charm? He alone escapes every magic charm who,
though he be carried away by the lower faculties of his soul, considers
good none of the objects that seem such to these faculties, who calls
good only what he by himself knows to be such, without being misled by
any deceptive appearance; and who regards as good not what he has to
seek, but what he possesses veritably. Then only could he in no way be
misled by any magic charm.
