Ethics Without a Foundation

One of the more uncomfortable questions in modern philosophy: can there be ethics without metaphysical grounding? If there is no God, no natural law, no cosmic order that ratifies our moral judgments, on what basis do those judgments stand?

The confident modern answer — pragmatism, contractualism, sophisticated forms of consequentialism — has generally been that ethics does not need cosmic grounding to be real. Moral claims can be defended, revised, and taught, and their absence of a metaphysical warrant does not stop them from being reasoned about with unusual seriousness.

The uneasy modern answer, less often voiced, is that the confident answer sometimes feels thin. A morality with no anchor beyond human agreement can be extended, refined, and lived; it is not obvious that it can, without losing itself, resist a determined political majority in the wrong mood.

The honest position may be that we do not yet know. The traditions that provided the older anchors have not disappeared, but their grip on the public imagination has loosened. What replaces them — if anything does — is being worked out, imperfectly, in real time.
