Various theories have been put forward in an attempt to explain what makes moral judgments justifiable. One of the main theories currently advocated in bioethics is a form of coherentism known as wide reflective equilibrium. In this paper, I argue that wide reflective equilibrium is not a satisfactory approach for justifying moral beliefs and propositions. A long-standing theoretical problem for reflective equilibrium has not been adequately resolved, and, as a result, the main arguments for wide reflective equilibrium are unsuccessful. Moreover, (...) practical problems that arise in using the method of wide reflective equilibrium undermine the idea that it is a viable approach for justifying moral judgments about cases and policies. Given that wide reflective equilibrium is the most prominent version of coherentism, these considerations call into question the coherentist approach to justification in bioethics. (shrink)

Even if there is a common morality, many would argue that it provides little guidance in resolving moral disputes, because universally accepted norms are both general in content and few in number. However, if we supplement common morality with commonly accepted factual beliefs and culture-specific norms and utilize coherentist reasoning, we can limit the range of acceptable answers to disputed issues. Moreover, in the arena of public policy, where one must take into account both legal and moral norms, the constraints (...) on acceptable answers will narrow the extent of reasonable disagreement even further. A consideration of the debate over legalization of assisted dying supports this claim. (shrink)
