This paper addresses the two extensional objections to the Humean Theory of Reasons—that it allows for too many reasons, and that it allows for too few. Although I won’t argue so here, manyof the other objections to the Humean Theoryof Reasons turn on assuming that it cannot successfully deal with these two objections.1 What I will argue, is that the force of the too many and the too few objections to the Humean Theorydepend on whether we assume that Humeans are committed to a thesis about the weight of reasons—one I call Proportionalism. In particular, I’ll show how a version of the Humean Theorythat rejects Proportionalism can reasonablyhope to escape both the too many and the too few objections. This will constitute my defense of this version of the Humean Theory. But then, separately, I will argue that this defense of the Humean Theoryis not ad hoc. I’ll argue that Humeans have no reason to accept Proportionalism in the first place. Or at least, no weightyone. There are three parts to the paper. In Part 1 we introduce the Humean Theoryand the too few reasons objection. I’ll first layout the objection, and then layout the basis for a response on behalf of myfavored version of the Humean Theory. There will be an obvious objection to my defense— but it will turn out to depend on the assumption of Proportionalism. This will constitute myargument that the susceptibilityof the Humean Theoryto..

This style of argument comes up everywhere in the philosophy of practical reason, leveled against theories of the norm of means-end coherence on intention, against Humean theories of reasons, and many other places. It comes up in normative moral theory – for example, in arguments against buck-passing. It comes up in epistemology, in discussions of how to account for the rational connection between believing the premises of a valid argument and believing its conclusion. And it comes up in political philosophy, where one of its most salient occurrences is in the so-called ‘leveling down’ objection to egalitarianism.

In this paper I explore why one might hope to, and how to begin to, develop an expressivist account of truth – that is, a semantics for ‘true’ and ‘false’ within an expressivist framework. I do so for a few reasons: because certain features of deflationism seem to me to require some sort of nondescriptivist semantics, because of all nondescriptivist semantic frameworks which are capable of yielding definite predictions rather than consisting merely of hand-waving, expressivism is that with which I am most familiar, and because I believe that certain problems about truth and particularly about paradox seem to me to look different, when seen through the lens of an expressivist theory. I don’t mean to defend such a theory in this paper, and indeed I have cast doubts on the ultimate prospects of the framework I will be employing here elsewhere.1 But I do think that seeing what an expressivist theory of truth would look like helps to shed light on both expressivism and on truth.

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in defeating knowledge by defeating epistemic rationality—the very kind of rationality that is entailed by knowledge, and in which Pascalian considerations do not play any role—even though epistemic rationality consists in having adequate evidence.

Expressing Our Attitudes pulls together over a decade of work by Mark Schroeder, one of the leading figures in contemporary metaethics. Two new and seven previously published papers weave treatments of propositions, truth, and the attitudes together with detailed development of competing alternative expressivist frameworks and discussion of their relative advantages. A substantial new introduction both offers new arguments of its own, and provides a map to reading these essays as a unified argument.Along with its sister volume, Explaining the Reasons We Share, this volume advances the theme that metaethical inquiry is continuous with other areas of philosophy.

The semantic theory of expressivism has been applied within metaethics to evaluative words like ‘good’ and ‘wrong’, within epistemology to words like ‘knows’, and within the philosophy of language, to words like ‘true’, to epistemic modals like ‘might’, ‘must’, and ‘probably’, and to indicative conditionals. For each topic, expressivism promises the advantage of giving us the resources to say what sentences involving these words mean by telling us what it is to believe these things, rather than by telling us what it would be for them to be true. This, in turn, absolves these theories of the burden of holding that there is any general answer to what it is for these sentences to be true. However, expressivism is famously subject to a deep and general problem about how to account for the meanings of complex sentences – a problem variously known as the ‘Frege-Geach’ or ‘embedding’ problem. In this paper I will be interested in whether there are reasons to think that the embedding problem looks less difficult for some of these applications for expressivism, than for others. In particular, in this paper I will be interested in the prospects for expressivism about what I will call epistemics – a class which I take to include epistemic modals like ‘might’ and ‘must’, sentential adverbs like ‘probably’, adjectives like ‘likely’ and ‘improbable’, and so-called ‘open’ indicative conditionals like ‘if the Fed doesn’t intervene, then the economy will enter a deflationary spiral’. There are several reasons to be particularly interested in expressivism about epistemics, relating both to the philosophical payoffs of such a view, and relating to the technical prospects for making it work. In other work I’ve touched on the especially interesting philosophical payoffs which make expressivism about epistemics interesting; in this paper I will be interested primarily in evaluating the possibility that there are better prospects for making expressivism about epistemics work than there are for making expressivism work about other topics. There are two main reasons why one might suspect that expressivism about epistemics will have better prospects than expressivism about many other topics, including in metaethics..

Douglas Portmore has recently argued in this journal for a "promising result" – that combining teleological ethics with "evaluator relativism" about the good allows an ethical theory to account for deontological intuitions while "accommodat[ing] the compelling idea that it is always permissible to bring about the best available state of affairs." I show that this result is false. It follows from the indexical semantics of evaluator relativism that Portmore's compelling idea is false. I also try to explain what might have led to this misunderstanding.

Fitting Attitudes accounts of value analogize or equate being good with being desirable, on the premise that ‘desirable’ means not, ‘able to be desired’, as Mill has been accused of mistakenly assuming, but ‘ought to be desired’, or something similar. The appeal of this idea is visible in the critical reaction to Mill, which generally goes along with his equation of ‘good’ with ‘desirable’ and only balks at the second step, and it crosses broad boundaries in terms of philosophers’ other commitments. For example, Fitting Attitudes accounts play a central role both in T.M. Scanlon’s [1998] case against teleology, and in Michael Smith [2003], [unpublished] and Doug Portmore’s [2007] cases for it. And of course they have a long and distinguished history.

This paper offers a simple and novel motivation for the Humean Theory of Reasons. According to the Humean Theory of Reasons, all reasons must be explained by some psychological state of the agent for whom they are reasons, such as a desire. This view is commonly thought¹ to be motivated by a substantive theory about the power of reasons to motivate known as reason internalism, and a substantive theory about the possibility of being motivated without a desire known as the Humean Theory of Motivation. Such a motivation would place substantial constraints on what form the Humean Theory of Reasons might take, and incur substantial commitments in metaethics and moral psychology. The argument offered here, on the other hand, is based entirely on relatively uncontroversial methodological considerations of perfectly broad applicability, and on the commonplace observation that while some reasons are reasons for anyone, others are reasons for only some. The argument is a highly defeasible one, but is supposed to give us a direct insight into what is philosophically deep about the puzzles raised for ethical theory by the Humean Theory of Reasons. I claim that it should renew our interest in the relationship between these two kinds of reason, and in particular in the explanation of reasons which seem to depend on desires or other psychological states

The last few decades have given rise to the study of practical reason as a legitimate subfield of philosophy in its own right, concerned with the nature of practical rationality, its relationship to theoretical rationality, and the explanatory relationship between reasons, rationality, and agency in general. Among the most central of the topics whose blossoming study has shaped this field, is the nature and structure of instrumental rationality, the topic to which Kant has to date made perhaps the largest contribution, under the heading of his treatment of hypothetical imperatives.

Semantics is the investigation of meaning, and semantic theories, including semantic theories about moral language, come in two very different kinds. Descriptive semantic theories are theories about what words mean. So descriptive moral semantic theories are theories about what moral words mean: words like ‘good’, ‘better’, ‘right’, ‘must’, ‘ought’, ‘reason’, and ‘rational’. In contrast, foundational semantic theories are theories about why words mean what they do, or more specifically, about what makes it the case that words mean what they do. So foundational moral semantic theories are theories about what makes it the case that moral words mean what they do: words like ‘good’, ‘better’, and so on. Since both kinds of theory are sometimes referred to as varieties of ‘moral semantics’, this article will cover both. Just as semantic theories themselves come in two kinds, descriptive semantics raises two very different kinds of issues. Some issues in descriptive semantics turn on the question of what kind of theory is required, in order to be able to account for the meanings of words – including of moral words, in particular. Such questions are questions about the nature of semantic theorizing. So, for example, according to truth-conditional theories, an adequate descriptive semantic theory needs to provide a recursive and compositional characterization of values for sentences which determine the truth conditions of each sentence. Whereas according to expressivist theories, an adequate descriptive semantic theory does not need to determine truth conditions at all, but does need to recursively and compositionally associate each sentence ‘P’ with a mental state – intuitively, with the state which constitutes what it is to think that P. Truth-conditional and expressivist theories involve very different conceptions of the nature of linguistic meaning, but their contrast is one of the most important issues in moral semantics, and they are not even the only live competitors. In contrast, other issues in descriptive semantics, rather than turning on what kind of theory is required, raise questions about specific properties of the meanings of particular words..

Buck-passers about value accept two theses about value, a negative thesis and a positive. The negative thesis is that the fact that something is valuable is not itself a reason to promote or appreciate it. The positive thesis is that the fact that something is valuable consists in the fact that there are other reasons to promote or appreciate it. Buck-passers suppose that the negative thesis follows from the positive one, and sometimes insist on it as if it is the central part of their view. But as I'll explain here, what we say about the negative thesis is orthogonal to what we say about the positive one

In the 1960s, Peter Geach and John Searle independently posed an important objection to the wide class of 'noncognitivist' metaethical views that had at that time been dominant and widely defended for a quarter of a century. The problems raised by that objection have come to be known in the literature as the Frege-Geach Problem, because of Geach's attribution of the objection to Frege's distinction between content and assertoric force, and the problem has since occupied a great deal of the attention both of defenders of broadly noncognitivist views, and of their critics. In this article I explain Geach and Searle's historical objections, and put the subsequent discussion into dialectical context, paying some attention to the developments along the way and how they have enhanced our overall understanding of the problem. The article covers a lot of territory, so we will only be able to see the highlights, along the way. For further reading, see the Works Cited.

Often, when there is a reason for you to do something, it is the kind of thing to motivate you to do it. For example, if Max and Caroline are deciding whether to go to the Alcove for dinner, Caroline might mention as a reason in favor, the fact that the Alcove serves onion rings the size of doughnuts, and Max might mention as a reason against, the fact that it is so difficult to get parking there this time of day. It is some sign—perhaps not a perfect sign, but some sign—that each of these really is a reason, that Max and Caroline feel the tug in each direction. Mention of the Alcove's onion rings makes them feel to at least some degree inclined to go, and mention of the parking arrangements makes them feel to at least some degree inclined not to. According to some philosophers, reasons for action always bear some relation like this to motivation. This idea is variously known as ‘ reasons internalism’, ‘internalism about reasons ’, or ‘the internal reasons theory’. According to other philosophers, not all reasons are related to motivation in any of the ways internalists say. This idea is known as ‘ reasons externalism’ or ‘externalism about reasons ’

This paper defends a simple thesis: that knowledge is belief for reasons that are both objectively and subjectively sufficient. I take a dogmatic approach, devoting the bulk of the paper to an explanation of what this means, and of why it explains both what knowledge is like, and why it is important; the theory is justified by its fruits. I go on to illustrate, by appeal to my main thesis, how knowledge comes to play some of the key roles that it does, including looking at Williamson’s arguments that knowledge is prime and for its distinctive explanatory role, as well as why my account explains and predicts the complicated behavior of knowledge in cases involving defeaters, defeated defeaters, and defeaters whose defeaters are defeated, as well as the different possible kinds of defeat – the primary source of complications in the Gettier literature. These facts are easily explained by the central thesis of the paper, without either giving up on the analysis of knowledge or resorting to arbitrary or ad hoc measures. Since the last five decades of literature might lead one to find it fairly audacious to propose an analysis of knowledge, a final section addresses the putative inductive grounds for general pessimism about the Gettierological project

Nondescriptivist views in many areas of philosophy have long been associated with the commitment that in contrast to other domains of discourse, there are no propositions in their particular domain. For example, the ‘no truth conditions’ theory of conditionals1 is understood as the view that conditionals don’t express propositions, noncognitivist expressivism in metaethics is understood as advocating the view that there are not really moral propositions,2 and expressivism about epistemic modals is thought of as the view that there is no such thing as the proposition that Jack might be at home, over and above the proposition that Jack is at home.3 Of course, it is nearly always acknowledged that advocates of a nondescriptivist theory need not deny that there are conditional, moral, or modal propositions ‘at the end of the day’ – for if they also endorse a deflationary reading of talk about propositions, as famously advocated by Simon Blackburn, then they can employ such deflationary talk just as much as the rest of us. They just don’t appeal to propositions to do any of the work in their theories. Rather, they ‘earn the right’ to talk about propositions.4 It is the aim of this paper to upset this way of thinking about the proper attitude of nondescriptivists toward propositions, and to advocate a more constructive and in some ways more radical alternative on behalf of the nondescriptivist. I will begin by introducing and developing a set of problems that are faced by any nondescriptivist theory which tries to do without propositions. All of these problems are easily solved by any view which postulates propositions across the board, but none of them are solved by merely deflationary talk about propositions – their most promising solutions require propositions to do real theoretical work, and therefore the problems themselves remind us of and illustrate some of the important reasons why it is worth positing propositions in the first place..
