In this paper, I argue that Marcus G. Singer’s attack on Actual Consequence Utilitarianism, as held by G.E. Moore, is inconclusive. Singer contends that Moore’s view is incoherent because it cannot provide a criterion of moral rightness and wrongness. Singer makes the historical claim that Moore intended his theory to provide such a criterion and the philosophical claim that any moral theory must provide such a criterion.I contend that Singer’s historical claim is false. While Moore uses the terms ‘criterion’ and ‘test’ in connection with his moral theory, an examination of Moore’s use of the terms shows that this notion does not involve the verifiability that is at the heart of Singer’s understanding of ‘criterion’.I then argue that Singer’s claim that moral judgments be verified begs the question against Moore’s realism. I argue that Singer must either reject semantic realism in general or give up the view that moral judgments are objectively true or false.

A coherent story is a story that fits together well. This notion plays a central role in the coherence theory of justification and has been proposed as a criterion for scientific theory choice. Many attempts have been made to give a probabilistic account of this notion. A proper account of coherence must not start from some partial intuitions, but should pay attention to the role that this notion is supposed to play within a particular context. Coherence is a property of an information set that boosts our confidence that its content is true ceteris paribus when we receive information from independent and partially reliable sources. We construct a measure cr that relies on hypothetical sources with certain idealized characteristics. A maximally coherent information set, that is, a set with equivalent propositions, affords a maximal confidence boost. cr is the ratio of the actual confidence boost over the confidence boost that we would have received, had the information been presented in the form of maximally coherent information, ceteris paribus. This measure is functionally dependent on the degree of reliability r of the sources. We use cr to construct a coherence quasi-ordering over information sets S and S : S is no less coherent than S just in case cr(S) is not smaller than cr(S ) for any value of the reliability parameter. We show that, on our account, the coherence of the story about the world gives us a reason to believe that the story is true and that the coherence of a scientific theory, construed as a set of models, is a proper criterion for theory choice.

Many contemporary philosophers of law agree that a necessary condition for a decision to be legally justified, even in a hard case, is that it coheres with established law. Some, namely Sartorius and Dworkin, have gone beyond that relatively uncontroversial claim and described the role of coherence in legal justification as analogous to its role in moral and scientific justification, on contemporary theories. In this, I argue, they are mistaken. Specifically, coherence in legal justification is sometimes specific to a branch of law, and there is nothing isomorphic to this in the models of moral and scientific justification. Although Dworkin and Sartorius rely on the concept of coherence, they do not explicate it. In the course of examining their views, this essay offers a partial analysis of coherence on their models. Finally, two canons of relevance, governing when global coherence considerations are appropriate to legal justification, are presented.

Quine argues, in “On the Nature of Moral Values” that a coherence theory of truth is the “lot of ethics”. In this paper, I do a bit of work from within Quinean theory. Specifically, I explore precisely what a coherence theory of truth in ethics might look like and what it might imply for the study of normative value theory generally. The first section of the paper is dedicated to the exposition of a formally correct coherence truth predicate, the possibility of which has been the subject of some skepticism. In the final two sections of the paper, I claim that a coherence theory in ethics does not reduce the practice of moral inquiry to absurdity, in practice as well as in principle.

Theories of moral, and more generally, practical reasoning sometimes draw on the notion of coherence. Admirably, Paul Thagard has attempted to give a computationally detailed account of the kind of coherence involved in practical reasoning, claiming that it will help overcome problems in foundationalist approaches to ethics. The arguments herein rebut the alleged role of coherence in practical reasoning endorsed by Thagard. While there are some general lessons to be learned from the preceding, no attempt is made to argue against all forms of coherence in all contexts. Nor is the usefulness of computational modelling called into question. The point will be that coherence cannot be as useful in understanding moral reasoning as coherentists may think. This result has clear implications for the future of Machine Ethics, a newly emerging subfield of AI.

We construct a probabilistic coherence measure for information sets which determines a partial coherence ordering. This measure is applied in constructing a criterion for expanding our beliefs in the face of new information. A number of idealizations are being made which can be relaxed by an appeal to Bayesian Networks.

Kenneth Goodpaster has criticized ethicists like Feinberg and Frankena for too narrowly circumscribing the range of moral considerability, urging instead that “nothing short of the condition of being alive” is a satisfactory criterion. Goodpaster overlooks at least one crucial objection: that his own “condition of being alive” may aIso be too narrow a criterion of moral considerability, since “being in existence” is at least as plausible and nonarbitrary a criterion as is Goodpaster’s. I show that each of the arguments that Goodpaster musters in support of his criterion can be used equally weIl to bolster “being in existence” as a test of moral considerability. Moreover, I argue that “being in existence” appears to be a stronger criterion overall, since it is broader. Until or unless a fuller justification is forthcoming of “being alive” as a satisfactory criterion of moral considerability-a justification which must demonstrate that “mere things,” included under the condition of “being in existence,” do not deserve moral consideration--Goodpaster’sthesis is confronted with a serious problem.

Coherence and Correspondence. Questions on a Programme of Reconciliation. Nicholas Rescher has recently proposed an original synthesis of the correspondence and the coherence idea. My purpose is a critical examination of this proposal. Against the background of a sketch of Rescher's general truth-conception and the synthesis mentioned above, I ask two questions. First: Given that coherence can only be the criterion of truth, if it forms a constitutive part of the concept of truth too; why not accept the inverse idea, which postulates the criterion-presence of correspondence? Secondly: Given the plausibility of the theoretical framework which allows the synthesis; why not accept a framework which allows a global synthesis between all truth-theories?

This paper concerns the normative status of coherence of desires, in the context of moral rationalism. I argue that 'desiderative coherence' is not tied to rationality, but is rather of pragmatic, instrumental, and sometimes moral value. This means that desire-based views cannot rely on coherence to support non-agent-relative accounts of moral reasons. For example, on Michael Smith's neo-rationalist view, you have 'normative reason' to do whatever your maximally coherent and fully informed self would want you to do, whether you want to do it or not. For these reasons to be non-agent-relative, coherence would have to be grounded in rationality, but I argue that it is not. I analyze, and reject, various strategies for establishing a coherence-rationality connection, considering in detail a purported analogy between desires and a priori beliefs, with particular attention to the case of mathematics.

In this paper I examine the question of whether ethicists are moral experts. I call people moral experts if their moral judgments are correct with high probability and for the right reasons. I defend three theses, while developing a version of the coherence theory of moral justification based on the differences between moral and nonmoral experience: The answer to the question of whether there are moral experts depends on the answer to the question of how to justify moral judgments. Deductivism and the coherence theory both provide some support for the opinion that moral experts exist in some way. I maintain – within the framework of a certain kind of coherence theory – that moral philosophers are 'semi-experts'.
