Richard Miller, the Hutchinson Professor in Ethics and Public Life in the Sage School of Philosophy, writes in this Washington Post op-ed that understanding the philosophy of libertarianism provides a basis for abandoning libertarianism.
He writes that "a committed libertarian must condemn as wrong forcibly taking a life-preerver ornamenting another's flagpole to save someone from drowning and must support the enforcement of contracts to enter into slavery and clauses in home sales forbidding subsequent sales to African-Americans. What a relief to abandom such committments, while relying on moral foundations for political choice enriched by lessons learned by libertarianism."
