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 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.

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.

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.

Whenever psychologists, neuroscientists, or philosophers draw conclusions about moral judgments in general from a small selected sample, they assume that moral judgments are unified by some common and peculiar feature that enables generalizations and makes morality worthy of study as a unified field. We assess this assumption by considering the six main candidates for a unifying feature: content, phenomenology, force, form, function, and brain mechanisms. We conclude that moral judgment is not unified on any of these levels and that moral science should adopt a more fine-grained taxonomic approach that studies carefully defined groups of moral judgments.

Traditional theories locate color in primary qualities of objects, in dispositional properties of objects, in visual fields, or nowhere. In contrast, we argue that color is located in properties of light. More specifically, light is red iff there is a property P of the light that typically interacts with normal human perceivers to give the sensation of red. This is an error theory, because objects and visual fields that appear red are not really red, since they lack the properties that make light red. We show how this light theory solves or avoids problems that afflict its competitors

General contrastivism holds that all claims of reasons are relative to contrast classes. This approach applies to explanation (reasons why things happen), moral philosophy (reasons for action), and epistemology (reasons for belief), and it illuminates moral dilemmas, free will, and the grue paradox. In epistemology, contrast classes point toward an account of justified belief that is compatible with reliabilism and other externalisms. Contrast classes also provide a model for Pyrrhonian scepticism based on suspending belief about which contrast class is relevant. This view contrasts with contextualism, invariantism, and Schaffer's contrastivism

Ideal for undergraduate courses in philosophy of law, this comprehensive anthology examines such topics as the concept of law, the dispute between natural law theorists and legal positivists, the relations between law and morality, criminal responsibility and legal punishment, the rights of the individual against the state, justice and equality, and legal evidence as compared with scientific evidence. The readings have been selected from both philosophy and law journals and include classic texts, contemporary theoretical developments, and well-known recent court cases. The text features extensive introductions that make even the most profound writings accessible to undergraduates.
