In a recent paper, Peter Singer suggests that some interesting new findings in experimental moral psychology support what he has contended all along—namely that intuitions should play little or no role in adequate justifications of normative ethical positions. Not only this but, according to Singer, these findings point to a central flaw in the method (or epistemological theory) of reflective equilibrium used by many contemporary moral philosophers. In this paper, we try to defend reflective equilibrium from Singer’s attack and, in part, we do this by discussing Singer’s own favoured moral methodology as outlined in his Practical Ethics . Although basing ethics solely on (certain kinds of) intuitions certainly is problematic, we argue, basing it solely on ‘reason’ gives rise to similar problems. The best solution would arguably be one which could strike a balance between the two—but, we suggest, this is precisely what reflective equilibrium is all about.

Humans have two kinds of beliefs, intuitive beliefs and reflective beliefs. Intuitive beliefs are a most fundamental category of cognition, defined in the architecture of the mind. They are formulated in an intuitive mental lexicon. Humans are also capable of entertaining an indefinite variety of higher-order or "reflective" propositional attitudes, many of which are of a credal sort. Reasons to hold "reflective beliefs" are provided by other beliefs that describe the source of the reflective belief as reliable, or that provide explicit arguments in favour of the reflective belief. The mental lexicon of reflective beliefs includes not only intuitive, but also reflective concepts.

even if an equilibrium is asymptotically stable, that is no guarantee that the system will reach that equilibrium unless we know that the system's initial state is sufficiently close to the equilibrium. Global stability of an equilibrium, when we have it, gives the equilibrium a much more powerful explanatory role. An equilibrium is globally asymptotically stable if the dynamics carries every possible initial state in the interior of the state space to that equilibrium. If an equilibrium is globally stable, it can have..

The paper addresses the possibility of providing a meta-justification of what appears to be crucial epistemic desiderata involved in the method of reflective equilibrium. I argue that although the method of reflective equilibrium appears to be widely in use in moral theorising, the prospects of providing a meta-justification of crucial epistemic desiderata are rather bleak. Nor is the requirement that a meta-justification be provided obviously misguided. In addition, I briefly note some of the implications of these results for our use of the method of reflective equilibrium and for the best interpretation of the method.

In 1955, Goodman set out to 'dissolve' the problem of induction, that is, to argue that the old problem of induction is a mere pseudoproblem not worthy of serious philosophical attention. I will argue that, under naturalistic views of the reflective equilibrium method, it cannot provide a basis for a dissolution of the problem of induction. This is because naturalized reflective equilibrium is -- in a way to be explained -- itself an inductive method, and thus renders Goodman's dissolution viciously circular. This paper, then, examines how the old problem of induction crept back in while nobody was looking.

A critique of inferences from 'is' to 'ought' plays a central role in Elqayam and Evans' defense of descriptivism. However, the reflective equilibrium strategy described by Goodman and embraced by Rawls, Cohen and many others poses an important challenge to that critique. Dual system theories may help respond to that challenge.

Practical equilibrium, like reflective equilibrium, is a way of deciding what to think about morality. It shares with reflective equilibrium the general thesis that there is some way in which a moral theory must, in order to be acceptable, answer to one’s moral intuitions, but it differs from reflective equilibrium in its specification of exactly how a moral theory must answer to one’s intuitions. Whereas reflective equilibrium focuses on a theory’s consistency with those intuitions, practical equilibrium also gives weight to a theory’s approval of one’s having those intuitions.

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.
