Wisdom literature is necessary. Fairy Tales, Myths, Legends, all use unknown forces to educate us. That’s just different from using wisdom (advice) as truth (decidability). One cannot deduce in argument from such premises. But one can seek counsel, and give counsel with wisdom.
It’s just a degree of precision: Analogy (wisdom) for broad, Virtues for less broad, General Rules for narrower, Law for narrower, science for narrower, and math for narrowest. This range allows us graceful increase and decrease in precision – or dishonestly, to obscure precision.
We must only know whether we are using the sufficient degree of precision for the question, whether we lack information for, or are ignorant of, further precision, or whether we are obscuring greater precision for dishonest purposes.
Theology uses all three – unfortunately.
