The rise of experimental philosophy has placed metaphilosophical questions, particularly those concerning concepts, at the center of philosophical attention. X-phi offers empirically rigorous methods for identifying conceptual content, but what exactly it contributes towards evaluating conceptual content remains unclear. We show how x-phi complements Rudolf Carnap’s underappreciated methodology for concept determination, explication. This clarifies and extends x-phi’s positive philosophical import, and also exhibits explication’s broad appeal. But there is a potential problem: Carnap’s account of explication was limited to empirical and logical concepts, but many concepts of interest to philosophers are essentially normative. With formal epistemology as a case study, we show how x-phi assisted explication can apply to normative domains.

Common-sense folk psychology and mainstream philosophy of action agree about decisions: these are under an agent's direct control, and are thus intentional actions for which agents can be held responsible. I begin this paper by presenting a problem for this view. In short, since the content of the motivational attitudes that drive deliberation and decision remains open-ended until the moment of decision, it is unclear how agents can be thought to exercise control over what they decide at the moment of deciding. I note that this problem might motivate a non-actional view of deciding?a view that decisions are not actions, but are instead passive events of intention acquisition. For without an understanding of how an agent might exercise control over what is decided at the moment of deciding, we lack a good reason for maintaining commitment to an actional view of deciding. However, I then offer the required account of how agents exercise control over decisions at the moment of deciding. Crucial to this account is an understanding of the relation of practical deliberation to deciding, an understanding of skilled deliberative activity, and the role of attention in the mental action of deciding.

Some of the things we do intentionally we do halfheartedly. I develop and defend an account of halfheartedness with respect to action on which one is halfhearted with respect to an action A if one’s overall motivation to A is weak. This requires getting clear on what it is to have some level of overall motivation with respect to an action, and on what it means to say one’s overall motivation is weak or strong. After developing this account, I defend the claim that one key functional expression of halfhearted action is the possession of impaired control over the action in question. Finally, I elucidate a puzzle that sometimes arises with respect to halfhearted action. The puzzle arises when an agent’s commitment in acting conflicts with an agent’s acceptance of poor performance.

Recent work in cognitive science suggests that conscious thought plays a much less central role in the production of human behavior than most think. Partially on the basis of this work, Peter Carruthers has advanced the claim that humans never consciously decide to act. This claim is of independent interest for action theory, and its potential truth poses a problem for theories of free will and autonomy, which often take our capacity to consciously decide to be of central importance. In this article, I examine the nature of conscious deciding and I argue that Carruthers fails to establish the claim that humans never consciously decide to act

The extensive involvement of nonconscious processes in human behaviour has led some to suggest that consciousness is much less important for the control of action than we might think. In this article I push against this trend, developing an understanding of conscious control that is sensitive to our best models of overt action control. Further, I assess the cogency of various zombie challenges—challenges that seek to demote the importance of conscious control for human agency. I argue that though nonconscious contributions to action control are evidently robust, these challenges are overblown

First, what are the psychological roots of our concept of free will? Second, how might progress on the first question contribute to progress regarding normative debates about the proper concept of free will? In sections two and three I address the first question. Section two discusses recent work in the experimental philosophy of free will, and motivates the study I report in section three. Section four reflects on the second question in light of the reported results. To preview, the results suggest that the psychological structure of our concept of free will is sensitive to three independent features: Liberty, Ensurance, and Consciousness. I argue this supports the view that our concept is incompatibilist more than the view that our concept is compatibilist, and I discuss two proposals regarding the normative upshot. On one proposal, these results might be taken to offer some support to incompatibilism about the proper concept. A second proposal, however, makes room for a much different upshot.

It is natural to think that at root, agents are beings that act. Agents do more than this, however – agents omit to act. Sometimes agents do so intentionally. How should we understand intentional omission? Recent accounts of intentional omission have given causation a central theoretical role. The move is well-motivated. If some form of causalism about intentional omission can successfully exploit similarities between action and omission, it might inherit the broad support causalism about intentional action enjoys. In this paper I consider the prospects for causalism about intentional omission. I examine two recent proposals: one Carolina Sartorio (2009) defends, and one Randolph Clarke (2010a) defends. I argue these versions fail, and for a similar reason. Reflection on the function of intention for agency brings this reason to light, and motivates a novel causalism about intentional omission. On the account I go on to defend necessarily, an agent J intentionally omits to A only if an intention of J’s with relevant content (or the intention’s acquisition) causes in J a disposition not to A. Though the causal work done by intentions to omit differs in some cases from the causal work done by intentions to act, it turns out that causalism about intentional behavior (i.e., about action and omission) is viable.

The power to exercise control is a crucial feature of agency. Necessarily, if S cannot exercise some degree of control over anything - any state of affairs, event, process, object, or whatever - S is not an agent. If S is not an agent, S cannot act intentionally, responsibly, or rationally, nor can S possess or exercise free will. In my dissertation I reflect on the nature of control, and on the roles consciousness plays in its exercise. I first consider the fragmented state of philosophical and empirical work on control. I argue that a mature philosophy of agency stands in need of a detailed personal-level account of control, and I begin by explicating a notion I call intentional control. On this explication, an agent J exercises intentional control in service of an intention X to the degree that behavior of J's for which X plays a (non-deviant) causal role approximates the representational content of X. With this explication in hand, I offer analyses of theoretically salient points along a degreed spectrum (covering, e.g., the exercise of minimal, successful, and perfect intentional control). Next, I develop an account of the degrees of intentional control's possession. This involves elucidation of ingredients of intentional control, i.e. those features of agents and environments that constitute an agent's causal potency and skill. It turns out that an agent's possession of control regarding an intention is intimately tied to her ability to repeatedly execute that intention across some specified (hypothetical) set of scenarios. Finally, I discuss a number of potentially fruitful applications of the account. In chapter three I confront a strong intuition, persistent in both philosophy and cognitive science, that consciousness is somehow intimately involved in the exercise of control. In this connection recent empirical work indicates the causal powers of consciousness remain poorly understood. I argue that Functional Agnosticism - the view that any claim regarding a function of consciousness for behavior is currently underdetermined by the data - is the wisest position on the causal powers of consciousness. Recognition of this unsatisfying state of affairs motivates reflection on what might enable progress beyond it. I argue that establishing a causal function for consciousness is facilitated by clarity on several issues. First, what is the sense of consciousness at issue? I isolate state consciousness, discuss the potential relevance of various types of conscious states, and distinguish between ambitious and modest approaches to the causal powers of state consciousness. In short, ambitious approaches seek to understand the causal contributions of a conscious mental state in virtue of the fact that the state is conscious; modest approaches seek to understand the causal contributions of conscious mental states, full stop. I argue that for various theoretical purposes, both approaches can be useful. Second, what is the sense of control at issue? I argue that for many important theoretical purposes, intentional control is the relevant sense. Finally, I illustrate the usefulness of clarity on these issues by examining recent work on the roles of conscious and unconscious vision for action. This work suggests that some important subset of our overt action is controlled by non-conscious processes. I apply insights developed earlier, noting common mistakes made in this literature, and highlighting important empirical possibilities these mistakes obscure. In later chapters I develop a novel account of conscious control. In chapter four I develop a central part of the account, which involves a view on the intentional structure of conscious trying. The leading view entails that conscious trying possesses a descriptive (or thetic) structure. Based on relevant empirical work concerning deafferented and paralyzed patients, I argue for the view that conscious trying is (at least) partially constituted by directive (or telic) structure. Finally, I argue that the exercise of conscious control is best understood as an exercise of intentional control for which the experience of trying plays a constitutive role. After presenting arguments for this view and defending the view against objections, I discuss the importance of conscious control for a mature philosophy of mind and agency

A majority of people regard the harmful side-effects of an agent’s behavior as much more intentional than an agent’s helpful side-effects. In this paper, I present evidence for a related asymmetry. When a side- effect action is an instance of harming, folk ascriptions are significantly impacted by the relative badness of either an agent’s main goal or her side- effect action, but not her attitude. Yet when a side- effect action is an instance of helping, folk ascriptions are sensitive to an agent’s expressed attitude, but not to the relative goodness of her main goal or side- effect. It seems that the connection between harmful side-effects and intentionality is, for many, uniquely impervious to the expressed attitude of the agent in question

In this paper, I examine the claim that self-consciousness is highly morally significant, such that the fact that an entity is self-conscious generates strong moral reasons against harming or killing that entity. This claim is apparently very intuitive, but I argue it is false. I consider two ways to defend this claim: one indirect, the other direct. The best-known arguments relevant to self-consciousness's significance take the indirect route. I examine them and argue that in various ways they depend on unwarranted assumptions about self-consciousness's functional significance, and once these assumptions are undermined, motivation for these arguments dissipates. I then consider the direct route to self-consciousness's significance, which depends on claims that self-consciousness has intrinsic value or final value. I argue what intrinsic or final value self-consciousness possesses is not enough to generate strong moral reasons against harming or killing.

In this paper, I offer evidence that folk views of free will and moral responsibility accord a central place to consciousness. In sections 2 and 3, I contrast action production via conscious states and processes with action in concordance with an agent's long-standing and endorsed motivations, values, and character traits. Results indicate that conscious action production is considered much more important for free will than is concordance with motivations, values, and character traits. In section 4, I contrast the absence of consciousness with the presence of consciousness in behaviorally identical agents. Most participants attribute free will to conscious agents, but not to nonconscious agents. Focusing in particular on two leading views of free will and moral responsibility, namely, Deep Self and Reasons-Responsive Views, I argue that these results present philosophers of mind and action with the following explanatory burden: develop a substantive theory of the connection between consciousness on the on..

What are the folk-conceptual connections between free will and consciousness? In this paper I present results which indicate that consciousness plays central roles in folk conceptions of free will. When conscious states cause behavior, people tend to judge that the agent acted freely. And when unconscious states cause behavior, people tend to judge that the agent did not act freely. Further, these studies contribute to recent experimental work on folk philosophical affiliation, which analyzes folk responses to determine whether folk views are consistent with the view that free will and determinism are incompatible (incompatibilism) or with the opposite view (compatibilism). Conscious causation of behavior tends to elicit pro-free will judgments, even when the causation takes place deterministically. Thus, when controlling for consciousness, many folk seem to be compatibilists. However, participants who disagree with the deterministic or cognitive scientific descriptions given of human behavior tend to give incompatibilist responses.

In a recent discussion, Walter Glannon discusses a number of ways we might try to minimize harm to patients who experience intraoperative awareness. In this response I direct attention to a possibility that deserves further attention. It might be that a kind of psychological intervention – namely, informing patients of the possibility of intraoperative awareness and of what to expect in such a case – would constitute a unique way to respect patient autonomy, as well as minimize the harm that typically follows intraoperative awareness events.

I argue that the neural realizers of experiences of trying are not distinct from the neural realizers of actual trying . I then ask how experiences of trying might relate to the perceptual experiences one has while acting. First, I assess recent zombie action arguments regarding conscious visual experience, and I argue that contrary to what some have claimed, conscious visual experience plays a causal role for action control in some circumstances. Second, I propose a multimodal account of the experience of acting. According to this account, the experience of acting is a temporally extended, co-conscious collection of agentive and perceptual experiences, functionally integrated and structured both by multimodal perceptual processing as well as by what an agent is, at the time, trying to do.

Research in psychology indicates that situations powerfully impact human behavior. Often, it seems, features of situations drive our behavior even when we remain unaware of these features or their influence. One response to this research is pessimism about human agency: human agents have little conscious control over their own behavior, and little insight into why they do what they do. In this paper we review classic and more recent studies indicating “the power of the situation,” and argue for a more optimistic response. In our view, though psychological research indicates situational influence, it also indicates that knowledge about the impact of situations on behavior can boost agents’ power to counteract harmful situational effects.

Ned Block has recently pressed a new criticism of the higher-order thought (HOT) theory of consciousness. HOT proponents have responded in turn. The exchange affords a chance to find some clarity concerning the essential commitments of HOT, as well as a chance to find clarity on the issues that divide Block and HOT proponents. In this paper I discuss the recent exchange, and I draw some lessons. First, I side with HOT proponents in arguing that new criticism presents no new problem for HOT. Second, I argue that the issues separating Block and HOT proponents suggest that two separate debates are being conflated, and I suggest that keeping them distinct will yield progress for consciousness studies.
