Abstract

In this paper, I question the dichotomy between fundamental moral disagreements, arising from divergences on moral principles, and superficial moral disagreements, that are expected to disappear under ideal epistemic circumstances. I claim that there are many other possibilities for moral disagreements, including moral disagreements that do not arise from different moral principles but would not disappear under ideal epistemic conditions. I describe two major kinds of such disagreements: semi-fundamental disagreements, which are made possible by the fact that the same moral rules can be applied in different ways to the same situations, and non-morally fundamental moral disagreements, which arise by the fact that moral truths are not the only potentially non-factual truths.
