I have read that at a certain point in Jewish History, many prominent rabbis were intentioned to discard this book attributed to Solomon. Why? Too many contradictions! E.g. the text reccomends both to “not answer a fool according to his folly”, according to 26:4, and to “answer a fool according to his folly”, as 26:5 advises. Another example: at the beginning, (chapters 1–9), it is declared that the fear of the Lord is the beginning of wisdom, but the following passages are much less theological, presenting wisdom as a transmissible human craft: however, with 30:1–14, the “words of Agur”, we return once more to the idea that God alone possesses wisdom. Also the account of Creation differs somehow from the simpler one in Genesis: God gives to this world via Wisdom , (see Proverbs 8:27–31) which existed before Creation and played a role in some way similar to that of Plato’s ideas.
Now the point is : can these contradictions be harmonized? I would also like to know more about the debates among rabbis regarding the canonicity of this Book.
