Hallucinations occur in a wide range of organic and psychological disorders, as well as in a small percentage of the normal population According to usual definitions in psychology and psychiatry, hallucinations are sensory experiences which present things that are not there, but are nonetheless accompanied by a powerful sense of reality. As Richard Bentall puts it, “the illusion of reality ... is the sine qua non of all hallucinatory experiences” (Bentall 1990: 82). The aim of this paper is to find (...) out what lends an experience ‘a sense of reality’: what features are required for an experience to feel ‘real’, in the relevant sense? I will investigate the claim that phenomenological features are largely responsible for a sense of reality, and will find this claim wanting. My suggestion is that a sense of reality is created and sustained by the larger nexus of the subject's beliefs. (shrink)

According to the Extended Mind thesis, the mind extends beyond the skull or the skin: mental processes can constitutively include external devices, like a computer or a notebook. The Extended Mind thesis has drawn both support and criticism. However, most discussions—including those by its original defenders, Andy Clark and David Chalmers—fail to distinguish between two very different interpretations of this thesis. The first version claims that the physical basis of mental features can be located spatially outside the body. Once we (...) accept that the mind depends on physical events to some extent, this thesis, though not obvious, is compatible with a large variety of views on the mind. The second version applies to standing states only, and has to do with how we conceive the nature of such states. This second version is much more interesting, because it points to a potential tension in our conception of minds or selves. However, without properly distinguishing between the two theses, the significance of the second is obscured by the comparative triviality of the first. (shrink)

Intentionality is customarily characterised as the mind’s direction upon its objects. This characterisation allows for a number of different conceptions of intentionality, depending on what we believe about the nature of the objects or the nature of the direction. Different conceptions of intentionality may result in classifying sensory experience as intentional and nonintentional in different ways. In the first part of this paper, I present a certain view or variety of intentionality which is based on the idea that the intentional (...) object of a sensory experience must be Independent; that is, an intentional object must be such that its existence doesn’t depend on being experienced (except in some very special cases). This means, for example, that sense-data understood as mind-dependent objects are not intentional objects, because their existence depends on the occurrence of an experience. In the second part of the paper, I will sketch a view of how sensory experiences can acquire an Independent object. (shrink)

In recent years, several philosophers have defended the idea of phenomenal intentionality: the intrinsic directedness of certain conscious mental events which is inseparable from these events’ phenomenal character. On this conception, phenomenology is usually conceived as narrow, that is, as supervening on the internal states of subjects, and hence phenomenal intentionality is a form of narrow intentionality. However, defenders of this idea usually maintain that there is another kind of, externalistic intentionality, which depends on factors external to the subject. We (...) may ask whether this concession to content externalism is obligatory. In this paper, I shall argue that it isn’t. I shall suggest that if one is convinced that narrow phenomenal intentionality is legitimate, there is nothing stopping one from claiming that all intentionality is narrow. (shrink)

Descartes's philosophy has had a considerable influence on the modern conception of the mind, but many think that this influence has been largely negative. The main project of The Subject's Point of View is to argue that discarding certain elements of the Cartesian conception would be much more difficult than critics seem to allow, since it is tied to our understanding of basic notions, including the criteria for what makes someone a person, or one of us. The crucial feature of (...) the Cartesian view defended here is not dualism--which is not adopted--but internalism. Internalism is opposed to the widely accepted externalist thesis, which states that some mental features constitutively depend on certain features of our physical and social environment. In contrast, this book defends the minority internalist view, which holds that the mind is autonomous, and though it is obviously affected by the environment, this influence is merely contingent and does not delimit what is thinkable in principle. Defenders of the externalist view often present their theory as the most thoroughgoing criticism of the Cartesian conception of the mind; Katalin Farkas offers a defence of an uncompromising internalist Cartesian conception.

Abstract: A theory of time is a theory of the nature of temporal reality, and temporal reality determines the truth-value of temporal sentences. Therefore it is reasonable to ask how a theory of time can account for the way the truth of temporal sentences is determined. This poses certain challenges for both the A theory and the B theory of time. In this paper, I outline an account of temporal sentences. The key feature of the account is that the primary (...) bearers of truth-values are not utterances, but sentences evaluated with respect to a time. I argue that unlike other views, the present proposal can meet the challenges faced both by the A and the B theory. (shrink)

Abstract: How exactly should the relation between a veridical perception and a corresponding hallucination be understood? I argue that the epistemic notion of ‘indiscriminability’, understood as lacking evidence for the distinctness of things, is not suitable for defining this relation. Instead, we should say that a hallucination and a veridical perception involve the same phenomenal properties. This has further consequences for attempts to give necessary and sufficient conditions for the identity of phenomenal properties in terms of indiscriminability, and for considerations (...) about the phenomenal sorites.

Abstract: This paper introduces and analyses the doctrine of externalism about semantic content; discusses the Twin Earth argument for externalism and the assumptions behind it, and examines the question of whether externalism about content is compatible with a privileged knowledge of meanings and mental contents.

Abstract: On several occasions (see e.g. Principles I/48) Descartes claims that sensations, emotions, imagination and sensory perceptions belong neither to the mind or to the body alone, but rather to their union. This seems to conflict with Descartes’s definition of “thought” given elsewhere, which classifies the same events as modes of a thinking substance, and hence depending for their existence only on minds. In this paper I offer an interpretation, which, I hope, will restore the coherence of Descartes’s dualist theory. (...) I argue that the ‘special modes’ of thinking are special because they are the immediate effects of the body on the mind. They thus depend for their existence on the body because of the general metaphysical principle that “Nothing comes from nothing”. Understood properly, this principle does not contradict the principle about the distinctness of substances. (shrink)

A complete and self-contained introduction to metaphysics, this anthology provides an extensive and varied collection of fifty-four of the best classical and contemporary readings on the subject. The readings are organized into ten sections: God, idealism and realism, being, universals and particulars, necessity and contingency, causation, space and time, identity, mind and body, and freewill and determinism. It features a substantial general introduction and detailed section introductions that set the selections in context and guide readers through them. Discussion questions and (...) detailed guides to further reading are also included. (shrink)

In this paper I argue against Twin-Earth externalism. The mistake that Twin Earth arguments rest on is the failure to appreciate the force of the following dilemma. Some features of things around us do matter for the purposes of conceptual classification, and others do not. The most plausible way to draw this distinction is to see whether a certain feature enters the cognitive perspective of the experiencing subject in relation to the kind in question or not. If it does, we (...) can trace conceptual differences to internal differences. If it doesn’t, we do not have a case of conceptual difference. Neither case supports Twin Earth externalism. (shrink)

The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privileged (...) access.
