What Would Aquinas Say ... About Posner?

Here is an except from what Richard Posner says today in his first posting as guest blogger for Leiter Reports:

"Well, much or even most morality seems based, rather, on instinct, emotion, custom, history, politics, or ideology, rather than on widely shared social goals. Think of the absolute prohibition of infanticide in contrast to the far more tolerant view of even late-term abortions. Think of the prohibition of bullfighting, cock fights, and cruelty to animals generally. Think of the rejection in our society of the Islamic punishment code, public nudity, polygamy, indentured servitude, chain gangs, voluntary gladiatorial combat, forced redistribution of wealth, preventive war, torture, the mutilation of corpses, sex with corpses, sex with nonobjecting animals, child labor, duelling, suicide, euthanasia, arranged marriages, race and sex discrimination. Are there really compelling reasons for these unarguable tenets of the current American moral code? One can give reasons for them, but would they be anything more than rationalizations? They have causes, that history, sociology, or psychology might elucidate, but causes are not reasons."
