Experimental philosophy is a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy. The present review focuses on research in experimental philosophy on four central questions. First, why is it that people's moral judgments appear to influence their intuitions about seemingly nonmoral questions? Second, do people think that moral questions have objective answers, or do they see morality as fundamentally relative? Third, do people believe in free will, and do they see free (...) will as compatible with determinism? Fourth, how do people determine whether an entity is conscious? (shrink)

Philosophical orthodoxy holds that pains are mental states, taking this to reflect the ordinary conception of pain. Despite this, evidence is mounting that English speakers do not tend to conceptualize pains in this way; rather, they tend to treat pains as being bodily states. We hypothesize that this is driven by two primary factors—the phenomenology of feeling pains and the surface grammar of pain reports. There is reason to expect that neither of these factors is culturally specific, however, and thus (...) reason to expect that the empirical findings for English speakers will generalize to other cultures and other languages. In this article we begin to test this hypothesis, reporting the results of two cross-cultural studies comparing judgments about the location of referred pains between two groups—Americans and South Koreans—that we might otherwise expect to differ in how they understand pains. In line with our predictions, we find that both groups tend to conceive of pains as bodily states. (shrink)

Experimental philosophy is a new approach to philosophy that incorporates the experimental methodologies of psychology, behavioral economics, and sociology. Experimental philosophers generally maintain that, in addition to traditional philosophical practices, these ways of gathering evidence can be instrumental in shedding light on philosophically important issues. Rather than relying on their own intuitions about specific cases, experimental philosophers perform systematic experiments to determine what intuitions people have about those cases. These intuitions are then used as evidence. In this context, four main (...) approaches to experimental philosophy are introduced, a sample of experimental philosophy’s results is offered, and some of the philosophical importance of those results is explained.

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. (shrink)

Philosophers and psychologists have experimentally explored various aspects of people’s understandings of subjective experience based on their responses to questions about whether robots “see red” or “feel frustrated,” but the intelligibility of such questions may well presuppose that people understand robots as experiencers in the first place. Departing from the standard approach, I develop an experimental framework that distinguishes 20 between “phenomenal consciousness” as it is applied to a subject (an experiencer) and to an (experiential) mental state and experimentally test (...) folk understandings of both subjective experience and experiencers. My findings (1) reveal limitations in experimental approaches using “artificial experiencers” like robots, (2) indicate that the standard philosophical conception of subjective experience in terms of qualia is distinct from that of the folk, and (3) show that folk intuitions do support a conception of qualia that departs from the philosophical conception in that it is physical rather than metaphysical. These findings have implications for the “hard problem” of consciousness. (shrink)

Recently, a number of philosophers have turned to folk intuitions about mental states for data about qualia and phenomenal consciousness. In this paper I argue that current research along these lines does not tell us about these subjects. I focus on a series of studies, performed by Justin Sytsma and Edouard Machery, to make my argument. Folk judgments studied by these researchers are mostly likely generated by a certain cognitive system – System One – that will generate the same data (...) whether or not we experience phenomenal consciousness. This is a problem for a range of current experimental philosophy research into consciousness or our concept of it. If experimental philosophy is to shed light into phenomenal consciousness, it needs to be better founded in an understanding of how we make judgments. (shrink)

This paper proposes the ‘AGENCY model’ of conscious state attribution, according to which an entity's displaying certain relatively simple features (e.g. eyes, distinctive motions, interactive behavior) automatically triggers a disposition to attribute conscious states to that entity. To test the model's predictions, participants completed a speeded object/attribution task, in which they responded positively or negatively to attributions of mental properties (including conscious and non-conscious states) to different sorts of entities (insects, plants, artifacts, etc.). As predicted, participants responded positively to conscious (...) state attributions only for those entities that typically display the simple features identified in the AGENCY model (eyes, distinctive motion, interaction) and took longer to deny conscious states to those entities.

Traditionally, the philosophical study of Folk Psychology has focused on how ordinary people (i.e., those without formal training in academic fields like Psychology, Cognitive Science, Philosophy of Mind, etc.) go about attributing mental states. Those working in this tradition have tended to focus primarily on intentional states, like beliefs and desires . Recently, though a body of work has emerged in the growing field of Experimental Philosophy that focuses on folk attributions of mental states that are not paradigmatically considered intentional. (...) This emerging discussion is concerned with figuring out how (and whether) ordinary people go about attributing mental states of qualitative experience, or what philosophers might call states of phenomenal consciousness . This paper briefly describes some of the primary works in the existing experimental philosophy literature and presents new experimental data that weigh on those hypotheses. Finally, it offers a cognitive model of the processes underlying attributions of mental states, called the Agency Model. (shrink)

The practice of conceptual analysis has undergone a revival in recent years. Although the extent of its role in philosophy is controversial, many now accept that conceptual analysis has at least some role to play. Granting this, I consider the relevance of empirical investigation to conceptual analysis. I do so by contrasting an extreme position (anti-empirical conceptual analysis) with a more moderate position (non-empirical conceptual analysis). I argue that anti-empirical conceptual analysis is not a viable position because it has no (...) means for resolving conceptual disputes that arise between seemingly competent speakers of the language. This is illustrated by considering one such dispute that has been pressed by a prominent advocate of anti-empirical conceptual analysis: Bennett and Hacker ( 2003 ) assert that psychological predicates only logically apply to whole living animals, but many scientists and philosophers use the terms more broadly. I argue that to resolve such disputes we need to empirically investigate the common understanding of the terms at issue. I then show how this can be done by presenting the results of three studies concerning the application of “calculates” to computers. (shrink)

In studying folk psychology, cognitive and developmental psychologists have mainly focused on how people conceive of non-experiential states such as beliefs and desires. As a result, we know very little about how non-philosophers (or the folk) understand the mental states that philosophers typically classify as being phenomenally conscious. In particular, it is not known whether the folk even tend to classify mental states in terms of their being or not being phenomenally conscious in the first place. Things have changed dramatically (...) in the last few years, however, with a flurry of ground-breaking research by psychologists and experimental philosophers. In this article I will review this work, carefully distinguishing between two questions: First, are the ascriptions that the folk make with regard to the mental states that philosophers classify as phenomenally conscious related to their decisions about whether morally right or wrong action has been done to an entity? Second, do the folk tend to classify mental states in the way that philosophers do, distinguishing between mental states that are phenomenally conscious and mental states that are not phenomenally conscious? (shrink)

Do philosophers and ordinary people conceive of subjective experience in the same way? In this article, we argue that they do not and that the philosophical concept of phenomenal consciousness does not coincide with the folk conception. We first offer experimental support for the hypothesis that philosophers and ordinary people conceive of subjective experience in markedly different ways. We then explore experimentally the folk conception, proposing that for the folk, subjective experience is closely linked to valence. We conclude by considering (...) the implications of our findings for a central issue in the philosophy of mind, the hard problem of consciousness. (shrink)

It would be a mistake to deny commonsense intuitions a role in developing a theory of consciousness. However, philosophers have traditionally failed to probe commonsense in a way that allows these commonsense intuitions to make a robust contribution to a theory of consciousness. In this paper, I report the results of two experiments on purportedly phenomenal states and I argue that many disputes over the philosophical notion of ‘phenomenal consciousness’ are misguided—they fail to capture the interesting connection between commonsense ascriptions (...) of pain and emotion. With this data in hand, I argue that our capacity to distinguish between ‘mere things’ and ‘subjects of moral concern’ rests, to a significant extent, on the sorts of mental states that we take a system to have. (shrink)

Common arguments for realism about phenomenal consciousness contend that this is a folk concept, with proponents expecting it to be lexicalised in ordinary language. In English, the word ‘experience’ is typically regarded as the best candidate. This predicts that ‘experience’ will be used to refer to mental states and episodes, not only in philosophical but also in ordinary discourse. We conduct a corpus study in order to assess this claim and to understand the actual use of the word in non-academic, (...) academic, and philosophical discourse. In non-academic discourse, uses that refer to knowledge or sources of knowledge, and to public events, are found to dominate. Uses that refer to mental states or episodes dominate only in the philosophy of mind (and not even in philosophy at large). (shrink)

Intuitively, proper referential extensions of psychological and moral terms exclude artifacts. Yet ordinary speakers commonly treat AI robots as moral patients and use psychological terms to explain their behavior. This paper examines whether this referential shift from the human domain to the AI domain entails semantic changes: do ordinary speakers literally consider AI robots to be psychological or moral beings? Three non-literalist accounts for semantic changes concerning psychological and moral terms used in the AI domain will be discussed: the technical (...) view (ordinary speakers express technical senses), the habit view (ordinary speakers subconsciously express ingrained social habits), and the emotion view (ordinary speakers express their own affective empathetic emotional states). I discuss whether these non-literalist accounts accommodate the results of relevant empirical experiments. The non-literalist accounts are shown to be implausible with respect to the ordinary use of agency-terms (e.g., “believe,” “know,” “decide,” etc.), and therefore I conclude that the concepts ordinary speakers express by agency-terms in reference to AI robots are similar to the concepts they express when applying the same terms to humans. When ordinary speakers extend emotion-terms and/or moral-patiency-terms to AI robots, however, I argue that semantic changes have taken place because ordinary speakers are in fact referring to their own affective empathetic emotional states rather than AI robots. This argument suggests that the judgments made by ordinary speakers regarding the proper referential extensions of emotion-terms and moral-patiency-terms are fallacious. (shrink)

Ad hoc concepts feature prominently in lexical pragmatics. A speaker can use a word or phrase to communicate an ad hoc concept that is different from the lexically encoded concept and the hearer can construct the intended ad hoc concept pragmatically during utterance comprehension. I argue that some philosophical concepts have origins as ad hoc concepts, and such concepts pose a challenge for experimental philosophy regarding these concepts. To illustrate this, I consider philosophers’ ‘what-it’s-like’-concepts and experimental philosophy of consciousness.

Philosophers and scientists refer to the special character of phenomenal consciousness, something supposedly obvious to all conscious persons. However, we had no empirical evidence about the folk view of consciousness until the first studies were carried out in the experimental philosophy of consciousness. According to the leading interpretation of these results, laypersons—people without academic knowledge about consciousness—do not notice the phenomenal aspect of consciousness. The aim of the article is to answer the question of whether we can trust these results. (...) I show that there are serious doubts about the validity of the experimental philosophy of consciousness research. As a result, the leading interpretation should be rejected, and the question about the folk nature of the concept of consciousness must be regarded as open. (shrink)

‘Space does not exist fundamentally: it emerges from a more fundamental non-spatial structure.’ This intriguing claim appears in various research programs in contemporary physics. Philosophers of physics tend to believe that this claim entails either that spacetime does not exist, or that it is derivatively real. In this article, I introduce and defend a third metaphysical interpretation of the claim: reductionism about space. I argue that, as a result, there is no need to subscribe to fundamentality, layers of reality and (...) emergence in order to analyse the constitution of space by non-spatial entities. It follows that space constitution, if borne out, does not provide empirical evidence in favour of a stratified, Aristotelian in spirit, metaphysics. The view will be described in relation to two particular research programs in contemporary physics: wave function realism and loop quantum gravity. (shrink)

This book aims to show that recent developments in neuroscience permit a defense of free will. Through language, human beings can escape strict biological determinism.

The existence of phenomenally conscious mental states is often taken to be obvious from first-person experience. Sytsma and Machery (2010) argued that if that is the case, then laypeople should classify mental states in the same way that philosophers typically do, treating states like seeing red and feeling pain similarly. We then presented evidence that they do not. This finding is interesting in its own right, however, outside of any implications for the philosophical debates concerning phenomenal consciousness. As such, we (...) attempted to explain our finding, presenting evidence that lay mental state ascriptions depend on valence judgments (that the mental states have a hedonic value for the subject). In this paper, I present new evidence that suggests against this valence account. I then provide evidence for a new explanation based on previous findings that laypeople tend to view both colors and pains as mind-independent qualitiesof objects outside the mind/brain. (shrink)

The uncanny valley—the unnerving nature of humanlike robots—is an intriguing idea, but both its existence and its underlying cause are debated. We propose that humanlike robots are not only unnerving, but are so because their appearance prompts attributions of mind. In particular, we suggest that machines become unnerving when people ascribe to them experience, rather than agency. Experiment 1 examined whether a machine’s humanlike appearance prompts both ascriptions of experience and feelings of unease. Experiment 2 tested whether a machine capable (...) of experience remains unnerving, even without a humanlike appearance. Experiment 3 investigated whether the perceived lack of experience can also help explain the creepiness of unfeeling humans and philosophical zombies. These experiments demonstrate that feelings of uncanniness are tied to perceptions of experience, and also suggest that experience—but not agency—is seen as fundamental to humans, and fundamentally lacking in machines.

Mind perception is the essence of moral judgment. Broadly, moral standing is linked to perceptions of mind, with moral responsibility tied to perceived agency, and moral rights tied to perceived experience. More specifically, moral judgments are based on a fundamental template of two perceived minds—an intentional agent and a suffering patient. This dyadic template grows out of the universal power of harm, and serves as a cognitive working model through which even atypical moral events are understood. Thus, all instances of (...) immorality are perceived to involve both blameworthy agents (i.e., acts) and suffering victims (i.e., consequences). Because moral cognition simultaneously concerns acts and consequences, theories which focus primarily on acts (i.e., deontology) or consequences (i.e., utilitarianism) do not accurately describe moral cognition. Indeed, the phenomenon of dyadic completion suggests that deontological and utilitarian concerns are not only simultaneously active, but also typically compatible and reinforcing: wrong acts have harmful consequences, and harmful consequences stem from wrong acts. The cognitive fusion of acts with consequences suggests that normative conflicts between deontology and utilitarianism are not reflected in everyday moral judgment. This in turn suggests that empirical conclusions drawn from moral dilemmas that pit utilitarianism against deontology—i.e., trolley problems—give an skewed account of moral cognition. (shrink)

It is received wisdom in philosophy and the cognitive sciences that individuals can be in emotional states but groups cannot. But why should we accept this view? In this paper, I argue that there is substantial philosophical and empirical support for the existence of collective emotions. Thus, while there is good reason to be skeptical about many ascriptions of collective emotion, I argue that some groups exhibit the computational complexity and informational integration required for being in genuinely emotional states.

Is phenomenal consciousness a problem for the brain sciences? An increasing number of researchers hold not only that it is but that its very existence is a deep mystery. That this problematic phenomenon exists is generally taken for granted: It is asserted that phenomenal consciousness is just phenomenologically obvious. In contrast, I hold that there is no such phenomenon and, thus, that it does not pose a problem for the brain sciences. For this denial to be plausible, however, I need (...) to show that phenomenal consciousness is not phenomenologically obvious. That is the goal of this article. †To contact the author, please write to: 1414 Simona Drive, Pittsburgh, PA 15201; e‐mail: [email protected]. (shrink)
