The Epistemology of Moral Intuition and Its Reliability
Quick fact
Evolutionary debunking arguments suggest that our moral intuitions may be products of natural selection favoring cooperation, not detectors of objective moral truths—meaning their reliability is questionable.

You feel it instantly: that action is wrong, that claim is unfair. But can you trust that gut feeling as evidence for what is truly right?

Understanding The Epistemology of Moral Intuition and Its Reliability
Think of moral intuition as a fast, automatic judgment—the feeling that something is right or wrong, without conscious deliberation. It's like recognizing a face: you just know it's familiar, even if you can't explain why. Similarly, we seem to 'just see' that causing needless pain is wrong. This 'seeming' is what philosophers call an intuition. In ethics, these intuitions are used as starting points for moral reasoning, like axioms in math. We test them against other beliefs and adjust accordingly. But are they trustworthy? A key challenge is that intuitions vary across cultures and time—what was once considered acceptable (slavery) now seems clearly wrong. This variation suggests intuitions might be influenced by upbringing and environment, not just objective truth. Yet, we also rely on them heavily. The question becomes: can these intuitions be justified as true, or are they just biases?
A deeper explanation
Moral intuitionism holds that some moral truths are self-evident and known through intuition, like basic logical truths. But this view faces the 'debunking challenge': if our intuitions were shaped by evolution to enhance survival, not to track moral truths, then they lack reliability—they’re aimed at fitness, not knowledge. For instance, our preference for kin may be adaptive but doesn't justify favoritism. Similarly, moral intuitions about purity or loyalty may have evolved for tribal cohesion, not to reflect objective morality. Another problem is disagreement: if two people have conflicting intuitions, at least one must be flawed, but which one? This mirror the general problem of peer disagreement. In response, some philosophers adopt coherentism, where intuitions are justified by their coherence with a broader set of beliefs—via 'reflective equilibrium.' But this still relies on intuition somewhere. The debate is central to whether we can have genuine moral knowledge.
