But since my intention is to write something useful for anyone who understands it, it seemed more suitable for me to search after the effectual truth of the matter rather than its imagined one.

For there is such a distance between how one lives and how one ought to live, that anyone who abandons what is done for what ought to be done achieves his downfall rather than his preservation.
