Posner believes that most moral understanding is acquired in childhood and largely controlled by parental example, peer pressure, and religion. Once acquired, moral beliefs and commitments can only be changed through "appeals to self-interest and emotional appeals that bypass our rational calculating faculty"...As usual with Posner, the writing is clear, the footnotes abundant and highly informative, and the index excellent. Highest recommendation for all collections.
