This paper proves a precisification of Hume’s Law—the thesis that one cannot get an ought from an is—as an instance of a more general theorem which establishes several other philosophically interesting, though less controversial, barriers to logical consequence.

This paper advances the following criticisms against the received view of implicatures: (1) implicatures are relations of pragmatic implication and not attempts to convey particular speaker meanings; (2) conversational implicatures are non-cancellable; (3) generalised conversational implicatures and conventional implicatures are necessary to preserve the cooperative assumption employing a conversational maxim of conveyability; (4) implicatures should be divided into utterance implicatures and assumption implicatures, not speaker implicatures and sentence implicatures; (5) trivial implicatures are genuine implicatures; (6) Grice’s theory of conversation cannot (...) explain most of his examples of particularised conversational implicatures; (7) the apparent attempts of explicit cancellation of implicatures are apologies, not attempts to avoid misunderstandings.

Either 1. the non-naturalist is in a state of mind that would treat as relevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters, or 2. the non-naturalist is in a state of mind that would treat as irrelevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters. The first state of mind is morally objectionable, for one should (...) not change one’s normative beliefs to pander to the patterns of some non-natural realm. The second state of mind is irrational, for if you think you are aiming to represent non-natural properties correctly, you should be interested to know which actions share a non-natural property and which do not, and you should be prepared to change your mind accordingly.

Non-naturalist realists are committed to the belief, famously voiced by Parfit, that if there are no non-natural facts then nothing matters. But it is morally objectionable to conditionalise all our moral commitments on the question of whether there are non-natural facts. Non-natural facts are causally inefficacious, and so make no difference to the world of our experience. And to be a realist about such facts is to hold that they are mind-independent. It is compatible with our experiences that there are (...) no non-natural facts, or that they are very different from what we think. As Nagel says, realism makes scepticism intelligible. So the non-naturalist must hold that you might be wrong that your partner matters, even if you are correct about every natural, causal fact about your history and relationship. But to hold that conditional attitude to your partner would be a moral betrayal. So believing non-naturalist realism involves doing something immoral. (shrink)

Are non-natural properties worth caring about? I consider two objections to metaethical non-naturalism. According to the intelligibility objection, it would be positively unintelligible to care about non-natural properties that float free from the causal fabric of the cosmos. According to the ethical idlers objection, there is no compelling motivation to posit non-natural normative properties because the natural properties suffice to provide us with reasons. In both cases, I argue, the objection stems from misunderstanding the role that non-natural properties play in (...) the non-naturalist's understanding of normativity. The role of non-natural properties is not to be responded to, but to "mark" which natural properties it is correct for us to respond to in certain ways. (shrink)

Neosentimentalist accounts of value need an explanation of which of the sentiments they discuss are pro-attitudes, which attitudes are con-attitudes, and why. I argue that this project has long been neglected in the philosophical literature, even by those who make extensive use of the distinction between pro- and con-attitudes. Using the attitudes of awe and respect as exemplars, I argue that it is not at all clear what if anything makes these attitudes pro-attitudes. I conclude that neither our intuitive sense (...) of the distinction nor the vague accounts of it that exist in the philosophical literature are especially helpful in sorting out the hard cases. What is needed is a more explicit and thorough account of what the valence of our attitudes consists in. (shrink)

Adviser: Professor Stefan Baumrin In the first chapter I introduce the distinction between metaethics and normative ethics and argue that metaethics, properly conceived, is a part of cognitive science. For example, the debate between rationalism and sentimentalism can be informed by recent empirical work in psychology and the neurosciences. In the second chapter I argue that the traditional view that one’s theory of semantics determines what one’s theory of justification must be is mistaken. Though it has been the case that (...) there are ‘typical’ combinations of semantic and justificational theories this is by no means forced on one. In the third chapter I examine two current kinds of expressivism; that of Blackburn and Copp. Each gives us an example of different combinations of semantic and justificatory theory. In Blackburn’s case he combines a use theory of meaning with a classic emotivist theory of justification, In Copp’s case it is a neo-Gricean philosophy of language with a realist’s theory of justification. I find both of these wanting as they ultimately collapse into relativistic subjectivism. In the fourth and fifth chapter I turn to developing Emotive Realism. The basic idea behind this view is that when someone says ‘x is wrong/right’ that person has (a) expressed a moral emotion about x and at the same time (b) expressed the belief that the emotion in (a) is the correct one to have. The belief expressed in (b) will be true or false depending on one’s theory of justification. In the fourth chapter I argue that we need separate semantic theories for thoughts and sentences. In the fifth chapter I fill in the details of Emotive Realism as I see it. (shrink)

This paper presents a new objection to the buck-passing account of value. I distinguish the buck-passing account of predicative value from the buck-passing account of attributive value. According to the latter, facts about attributive value reduce to facts about reasons and their weights. But since facts about reasons’ weights are themselves facts about attributive value, this account presupposes what it is supposed to explain. As part of this argument, I also argue against Mark Schroeder's recent account of the weights of (...) reasons, which purports to explain the weights of reasons in terms of further reasons without circularity. I then argue that if we abandon the buck-passing account of attributive value, it would be ad hoc and unjustifiable to continue to endorse the buck-passing account of predicative value. In short, there seems to be little hope for the buck-passing account in either form. The paper ends by sketching a novel alternative theory according to which reasons are analysed in terms of the attributive value of motives. I suggest that a normative reason to is something that would be a good motive for -ing. At least at first glance, this view has numerous merits and few problems. (shrink)

This thesis investigates the conceptual relationship between laws of nature and free will. In order to clarify the discussion, I begin by distinguishing several questions with respect to the nature of a law: i) do the laws of nature cover everything that happens? ii) are they deterministic? iii) can there be exceptions to universal and deterministic laws? iv) do the laws of nature govern everything in the world? In order to answer these questions I look at three widely endorsed accounts (...) of laws: "Humean" regularity accounts, laws as relations among universals, and the dispositional essentialist account. I argue that there is nothing in the very nature of a law - in any of the accounts surveyed - that implies a positive answer to questions (i) and (ii). I show that this has important consequences for the free will problem. I then turn to the compatibility of free will and determinism. I focus on the Humean view and the dispositional essentialist account of laws. And the bulk of this discussion concerns the consequence argument, especially the question of whether the laws of nature are "up to us". I show that, on the dispositional conception of laws, there is no sense in which the laws of nature are up to us, contrary to the Humean view. However, this does not mean that there is no room for free will on the dispositional account. I argue that free will requires the laws of nature to be limited in scope, rather than being indeterministic. I conclude by showing that this allows one to resist the claim that indeterminism rules out free will. (shrink)

A dispute exists about whether bioethics should become a new discipline with its own methods, competency standards, duties, honored texts, and core curriculum. Unique expertise is a necessary condition for disciplines. Using the current literature, different views about the sort of expertise that might be unique to bioethicists are critically examined to determine if there is an expertise that might meet this requirement. Candidates include analyses of expertise based in "philosophical ethics," "casuistry," "atheoretical or situation ethics," "conventionalist relativism," "institutional guidance," (...) "regulatory guidance and compliance," "political advocacy," "functionalism," and "principlism." None succeed in identifying a unique area of expertise for successful bioethicists that could serve as a basis for making it a new discipline. Rather expertise in bioethics is rooted in many professions, disciplines and fields and best understood as a second-order discipline. (shrink)

In this paper I compare and contrast Rawls’s notion of reflective equilibrium with Wellman‘s notion of conductive argument. In the course of so doing I will address two key questions: Are conduc-tive argument and reflective equilibrium best understood as modes of reasoning or types of argument? and What relationship, if any, is there between them?

The article protests against the usage of ethical codes by business organisations. It asserts that professionals are in a different situation to that of employees; and that with the latter ethical codes are used by management to ensure compliance and are devoid of ethical content. Ethical codes it is argued are part of management's control system in a time of flatter organisational structures with a far wider span of control. It is also asserted that the ambitions of some to utilise (...) ethical codes so that the business organisation is able to engender societal change is dangerous and likely, if successful, to return us to an age which we could not seriously desire to re-visit.
