May one not forestall delirium or insanity, if one become aware of
their approach? To begin with, insanity does not happen to a sage, and
if it does, this accident should be considered one of those inevitable
things which depend from fatality, and in which case one should direct
one's path less according to his intrinsic quality than according to
circumstances; for perhaps the poison one might select to eject the
soul from the body might do nothing but injure the soul.
