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)

The Doctrine of Double Effect [DDE] states roughly that it is harder to justify causing or allowing harm as a means to an end than it is to justify conduct that results in harm as a side effect. This chapter argues that a theory of deontological constraints on harming needs something like the DDE in order to avoid the charge that it reflects a narcissistic obsession with the cleanliness of our own hands. Unfortunately, the DDE is often interpreted as maintaining (...) that we must avoid acting with certain intentions, which, this chapter contends, embodies an equally narcissistic obsession with the purity of our own hearts. The chapter argues that the DDE is better interpreted as a denial of the Machiavellian idea that beneficial ends justify harmful means. On this view, the objective fact that our conduct will secure benefits for some individuals at the expense of other individuals weakens the extent to which those benefits count as reasons to engage in that conduct. The chapter argues that this version of the DDE provides a plausible, non-narcissistic foundation for deontological constraints. (shrink)

What is it exactly that we are attributing to a thing when we judge it to be good? According to the orthodox answer, at least in some cases when we judge that something is good we are attributing to it a monadic property. That is, good things are “just plain good.” I reject the orthodox view. In arguing against it, I begin with the idea that a plausible account of goodness must take seriously the intuitive claim that there is something (...) in common between moral and non-moral goodness—something in virtue of which it makes sense to call ‘good’ both the things that are morally good and the things that are non-morally good. However, it is implausible that all judgments about the goodness of things attribute a monadic property to those things, as this does not capture what we mean when we judge something to be non-morally good. Instead, I propose and defend my own relational theory of goodness according to which goodness is a relation that holds between things and ends (or goals). That is, goodness is a relational property such that to be good is to be related in the relevant way to some goal or another. This is true in both the mundane everyday cases and in loftier cases concerned with moral goodness. (shrink)

This article analyzes the thesis of ethical relativism, as defended by Alchourrón and Bulygin. These authors offer, on the one hand, a suggestive conception according to which the question “what are our obligations?” is equivalent to thinking about what is to be done; on the other hand, they defend a relativist conception of ethics. They present three objections to constructivist accounts of ethics that are not relativist: a) the argument of the burden of the proof; b) a version of the (...) dilemma of Euthyphro, and c) the argument of particularism. This article presents counterarguments to these objections in the attempt to show that they are not conclusive and that a space therefore remains for objectivity in the normative sphere. Keywords: Alchourrón-Bulygin, ethical relativism, ethical constructivism, burden of proof, particularism. (shrink)

The subject-matter of this essay is the moral status of nature. This subject is dealt with in terms of normative reasons. The main question is if there are direct normative reasons to care for nature in addition to the numerous indirect normative reasons that there are for doing so. Roughly, if there is some such reason, and that reason applies to any moral agent, then nature has direct moral status as I use the phrase. I develop the notions of direct (...) normative reason and direct moral status in detail and identify and discuss the two main types of theory according to which nature has direct moral status: analogy-based nature-considerism and non-analogy-based nature-considerism. I argue for the plausibility of a particular version of the latter, but against the plausibility of any version of the former. The theory that is representative of AN claims that nature has direct moral status in virtue of possessing interests. Proponents of this theory fail to show that nature has interests of the kind that they reasonably want to ascribe to it, and that interests of this kind are morally significant. In contrast to AN, NN comes in a variety of different forms. I elaborate a version of NN according to which there are direct normative reasons to care for nature in virtue of its unique complexity, and its indispensability. I argue that even if these reasons should turn out not to apply to any moral agent, they are still genuine direct normative reasons: there is nothing irrational or misdirected about them. Finally, I show how the question of whether there are direct normative reasons to care for nature is relevant to private and political decision-making concerning nature. This is exemplified with a case from the Swedish mountain region. (shrink)

What kinds of fundamental limits are there in how capable artificial intelligence (AI) systems might become? Two questions in particular are of interest: (1) How much more capable could AI become relative to humans, and (2) how easily could superhuman capability be acquired? To answer these questions, we will consider the literature on human expertise and intelligence, discuss its relevance for AI, and consider how AI could improve on humans in two major aspects of thought and expertise, namely simulation and (...) pattern recognition. We find that although there are very real limits to prediction, it seems like AI could still substantially improve on human intelligence. (shrink)

MA Thesis. Biomedical ethics does not lend itself to easy categorisation as either a 'theoretical' or a 'practical' enterprise because inquiry into the quandaries of morality requires both situational and 'translocal' perspectives. These types of investigation bring into question the legitimacy of the theory/practice divide that has dominated intellectual thought since antiquity. This division hinders the development of bioethics by fostering internal dispute within the discipline regarding appropriate methodology and the practice of clinical ethics. In this thesis, I argue that (...) much of these disciplinary disjunctions are due to an undue labeling of bioethics as either 'applied ethics' or 'practical ethics', and a failure to recognise the intricate way in which theory and practice inform each other and are integral and interrelated parts of moral deliberation. I argue for an integration of the theory and practice of bioethics. (shrink)

Without doubt, the global challenges we are currently facing—above all world poverty and climate change—require collective solutions: states, national and international organizations, firms and business corporations as well as individuals must work together in order to remedy these problems. In this chapter, I discuss climate change mitigation as a collective action problem from the perspective of moral philosophy. In particular, I address and refute three arguments suggesting that business firms and corporations have no moral duty to reduce greenhouse gas emissions: (...) (i) that business corporations are not appropriate addressees of moral demands because they are not moral agents, and (ii) that to the extent that they are moral agents their primary moral obligation is to their owners or shareholders, and (iii) the appeal to the difference principle: that individual business corporations cannot really make a significant difference to successful climate change mitigation.
