A strong tradition in philosophy denies the possibility of moral dilemmas. Recently, several philosophers reversed this tradition. In this dissertation, I clarify some fundamental issues in this debate, argue for the possibility of moral dilemmas, and determine some implications of this possibility. ;In chapter I, I define moral dilemmas roughly as situations where an agent morally ought to adopt each of two alternatives but cannot adopt both. Moral dilemmas are resolvable if and only if one of the moral oughts overrides the other. ;In chapter II, I criticize several opponents of moral dilemmas, including utilitarians, Kant, Aquinas, and Ross. My main criticism is that no opponent of moral dilemmas can adequately justify moral residue . ;Chapters III and IV concern the two main arguments against the possibility of moral dilemmas. First, the argument for 'ought' implies 'can' runs as follows. If the agent cannot adopt both, then it is not the case that the agent ought to adopt both. But the agent ought to adopt both, since the agent ought to adopt each . Thus, the defining judgements of a moral dilemma seem to imply a contradiction. In response, I argue that the relation between 'ought' and 'can' is not a logical implication but a conversational implicature. ;Chapter IV concerns the argument from 'ought' implies 'permitted': If the agent ought to adopt one alternative, then the agent is permitted to adopt that alternative, which means that it is not the case that the agent ought not to adopt that alternative. But the agent ought not to adopt that alternative, since the agent ought to adopt the other alternative and cannot adopt both. I respond that 'ought' does not logically imply but conversationally implicates 'permitted'. ;In chapter V, I argue that, despite recent claims, both moral realism and anti-realism are compatible with the possibility of moral dilemmas. Thus, there are several reasons to accept and no reasons to deny the possibility of moral dilemmas

In this short paper, I argue that the phenomenology of moral judgment is not unified across different areas of morality (involving harm, hierarchy, reciprocity, and impurity) or even across different relations to harm. Common responses, such as that moral obligations are experienced as felt demands based on a sense of what is fitting, are either too narrow to cover all moral obligations or too broad to capture anything important and peculiar to morality. The disunity of moral phenomenology is, nonetheless, compatible with some uses of moral phenomenology for moral epistemology and with the objectivity and justifiability of parts of morality

This chapter criticizes moral intuitionism, which claims that some moral beliefs are justified independently of any ability to infer them from other beliefs. It defines moral intuitionism, and argues that beliefs need confirmation when they are partial, controversial, emotional, or formed in circumstances that are conducive to illusion or unreliability. Empirical research is cited to show that moral beliefs are subject to these problems and, hence, need confirmation by some inference, so moral intuitionism cannot solve the skeptical regress problem.

We show that classical two-valued logic is included in weak extensions of normal three-valued logics and also that normal three-valued logics are best viewed not as deviant logics but instead as strong extensions of classical two-valued logic obtained by adding a modal operator and the right axioms. This article develops a general method for formulating the right axioms to construct a two-valued system with theorems that correspond to all of the logical truths of any normal three-valued logic. The extended classical system can then express anything that can be expressed in the three-valued logic, so there can be no reason to abandon two-valued logic in favor of three-valued logic. Moreover, the two-valued modal system is preferable, because it enables us to study interactions of different operators with different rationales. It also makes it easier to introduce quantifiers and iteration. Nothing is lost and much is gained by choosing the extended two-valued approach over normal three-valued logics

Recent exchanges among Harman, Thomson, and their critics about moral explanations have done much to clarify this two-decades-old debate. I discuss some points in these exchanges along with five different kinds of moral explanations that have been proposed. I conclude that moral explanations cannot provide evidence within an unlimited contrast class that includes moral nihilism, but some moral explanations can still provide evidence within limited contrast classes where all competitors accept the necessary presuppositions. This points towards a limited version of moral skepticism.

The rule ‘Keep your promises’ is often presented as a challenge to consequentialism, because the ground of your moral obligation not to break a promise seems to lie in the past fact that you made the promise, which is not a consequence of the act. A different picture emerges, however, when we move beyond the question of whether you have any moral obligation at all to the related question of how strong that obligation is.If I promise to meet you and some other mutual friends for a casual lunch, then my moral obligation to meet you is not as strong as when I promise to drive you to the airport to catch an important flight. Why not? The natural answer is that, if I break the lunch promise, not much bad will happen. You will still have a pleasant lunch with our other friends, and you and I can still have lunch some other time. I have some moral obligation to meet you, but not a very strong one. In contrast, if I break my driving promise, then my failure will cause much more harm, assuming that you will not find another way to get to the airport in time for your flight. These harmful consequences to you seem to be what give strength to my moral obligation to keep this promise.The relevant kind of strength is measured by how much is needed to override the obligation. I would need much stronger reasons to justify breaking my promise to drive you to the airport than to justify breaking my promise to meet you for lunch. The fact that my teenage child is sick at home might be enough to justify missing the lunch, even if the teenager would be safe at …

Expressivism faces four distinct problems when evaluative sentences are embedded in unassertive contexts like: If lying is wrong, getting someone to lie is wrong, Lying is wrong, so Getting someone to lie is wrong. The initial problem is to show that expressivism is compatible with - being valid. The basic problem is for expressivists to explain why evaluative instances of modus ponens are valid. The deeper problem is to explain why a particular argument like - is valid. The deepest problem is to explain the meanings of evaluative conditionals like . Expressivists can solve the initial and basic problems simply by acknowledging that evaluative sentences have minimal truth aptness, but the deeper and deepest problems require more. The deepest problem cannot be solved even with the semantics of Gibbard and Blackburn, as is shown by an extension of Dreier’s hiyo argument

In The Architecture of Reason, Robert Audi claims that good reasoning always has some foundation in experience. It is not clear, however, precisely what kind of experience is supposed to ground practical reasoning. It is also not clear whether inference is necessary for a belief to be justified, even when the source of the belief is experience without inference. Finally, it is not clear why beliefs based on some kinds of experience would not need to be justified by inference when beliefs based on other experiential sources (such as extra-sensory perception) do not share this epistemically privileged status

The chapter focuses on the philosophical debate between moral motivational internalism and externalism. The author analyzes and thereby challenges the conceptual problems underlying this quarrel in relation to the apparent empirical findings on psychopathy. Major obstacles in making progress in this debate are conceptual and methodological problems. First, there is not a clear-cut and undisputed definition of moral internalism. Second, empirical results about a lack of moral judgment are not forthcoming, since it is not certain how to test such an impairment, and also who is to count as psychopaths in the first place. In conclusion both externalists and internalists are wrong in some respect: internalists in that they see an internal connection between moral judgments and motivation, externalists in their rejection of internalism on grounds of findings about psychopathy.

This essay invokes a technical framework of contrast classes within which Pyrrhonians can accept (or deny) knowledge claims that are relativized to specific contrast classes, but avoid all unrelativized knowledge claims and all presuppositions about which contrast classes are really relevant. Pyrrhonians can then assert part of the content of everyday knowledge claims without privileging the everyday perspective or any other perspective. This framework provides a precise way to understand the central claims of neo-Pyrrhonism while avoiding most, if not all, of the problems and objections raised by its critics.

This chapter explains moral coherentism as the view that some moral beliefs are justified by virtue of cohering with a system of belief that is coherent in the sense that it is consistent, connected, and comprehensive. Second-order beliefs about reliability are introduced to handle standard objections to coherentism. It concludes that coherence can make some moral beliefs justified out of a modest contrast class, but not out of an extreme contrast class with moral nihilism. This final chapter, together with the rest of Part 2, thus leads to moderate moral skepticism.

No topic in informal logic is more important than begging the question. Also, none is more subtle or complex. We cannot even begin to understand the fallacy of begging the question without getting clear about arguments, their purposes, and circularity. So I will discuss these preliminary topics first. This will clear the path to my own account of begging the question. Then I will anticipate some objections. Finally, I will apply my account to a well-known and popular response to scepticism by G. E. Moore.

This chapter discusses expressivism as a form of moral skepticism that denies the truth-aptness of moral beliefs and judgments. It focuses on whether expressivists can solve the problem of embedding by allowing that some moral beliefs have a minimal kind of truth, and whether expressivists can account for the apparent objectivity of moral beliefs. It concludes that if expressivists succeed in mimicking all apparently realistic moral language, then expressivism does not really matter to moral epistemology.
