The contradictions are difficult but wisdom has always been like that. See for example the book of Proverbs, it’s full of contradictory advice.

“Do not answer a fool according to his folly, lest you also be like him.”

Versus

“Answer a fool according to his folly, lest he be wise in his own eyes.”

The skill is to understand the truth of both statements, and to discern when to apply each one.
