XLVI. Remember that thy mind is of that nature as that it becometh altogether unconquerable, when once recollected in herself, she seeks no other content than this, that she cannot be forced: yea though it so fall out, that it be even against reason itself, that it cloth bandy. How much less when by the help of reason she is able to judge of things with discretion? And therefore let thy chief fort and place of defence be, a mind free from passions. A stronger place, (whereunto to make his refuge, and so to become impregnable) and better fortified than this, hath no man. He that seeth not this is unlearned. He that seeth it, and betaketh not himself to this place of refuge, is unhappy.
