Eerdman’s published this work quite recently. Penchansky argues here that
Israelite wisdom literature … records the disputes of ancient sages over basic human questions: What is the purpose of life? Is God just? Why do we suffer? Does God even exist? Penchansky sees conflicting answers to these questions in Proverbs, Job, Ecclesiastes, Ben Sira, and the Wisdom of Solomon — and does not try to harmonize them. Instead, he finds meaning in the very dissonance and contradiction within these texts.
My review is online here.
