“[Integrity] bids us to act on what the Aristotelian tradition has long called right reason: on reason unfettered by contrary feelings; on our rational appreciation of basic goods, undistorted by partiality or hostility that would blind us to some of the people or goods before us. Thus, morality rules out invidious discrimination, or callousness toward the goods of some. And it rules out trampling some basic goods on our way to others – or more precisely, intending harm to someone’s most basic interests as a means to other benefits. This explains how there can be absolute rights, such as those against torture or intentional killing of the innocent.”
