I critically examine the view that Descartes’s independence conception (IC) of substance plays a crucial role in his “separability argument” for substance dualism. I argue that IC is a poisoned chalice. I do so by considering how an IC-based separability argument fares on two different ways of thinking about principal attributes. On the one hand, if we take principal attributes to be universals, then a separability argument that deploys IC establishes a version of dualism that is unacceptably strong. On the (...) other hand, if we take principal attributes to be tropes, then IC introduces challenges which undermine the argument. This is partly because the assumption of tropes makes it possible to distinguish several versions of substance dualism, versions which differ with respect to their degree of generality. I argue that taking principal attributes to be tropes makes it challenging to establish any of these versions by way of an IC-based separability argument. I conclude the paper by suggesting a way forward for the proponent of the separability argument. (shrink)

I lay out the framework for my theory of sensory imagination in “Imagining as a guide to possibility.” Sensory imagining involves mental imagery , and crucially, in describing the content of imagining, I distinguish between qualitative content and assigned content. Qualitative content derives from the mental image itself; for visual imaginings, it is what is “pictured.” For example, visually imagine the Philadelphia Eagles defeating the Pittsburgh Steelers to win their first Super Bowl. You picture the greenness of the field and (...) the football’s brown oblong shape. Some of what you imagine isn’t explicitly pictured, however. That it is Sunday, that it is the Super Bowl: these facts are assigned. (shrink)

This essay briefly describes a few of the problems associated with using personhood language to defend the right to life of the pre‐implantation embryo. Arguing that an immaterial soul explains the personal identity of an embryo is problematic for many people because there is no apparent spiritual activity in the unborn. While some scholars argue that the embryo has the potential to act as an adult person and thus should be protected from harm, others contend that potentiality alone is insufficient (...) reason to ascribe special moral worth to the embryo in utero. For Thomas Aquinas, the soul is not only the life‐principle that organizes the human body, but it is also that by which the human being thinks and wills. By making suitable corrections to Aristotle's hylomorphic depiction of the soul–body relation, I suggest that a rational soul must be present from the moment of conception and that it is at the service of the person. What is of critical importance here is to accept that a human being is present from the moment of conception, something the vast majority of embryologists maintain, notwithstanding the inveiglement of those who state that the pre‐implantation blastocyst is simply a disorganized clump of cells.

Modal intuitions are the primary source of modal knowledge but also of modal error. According to the theory of modal error in this paper, modal intuitions retain their evidential force in spite of their fallibility, and erroneous modal intuitions are in principle identifiable and eliminable by subjecting our intuitions to a priori dialectic. After an inventory of standard sources of modal error, two further sources are examined in detail. The first source - namely, the failure to distinguish between metaphysical possibility (...) and various kinds of epistemic possibility - turns out to be comparatively easy to untangle and poses little threat to intuition-driven philosophical investigation. The second source is the local misunderstanding of one's concepts . This pathology may be understood on analogy with a patient who is given a clean bill of health at his annual check-up, despite his having a cold at the time of the check-up: although the patient's health is locally disrupted, his overall health is sufficiently good to enable him to overcome the cold without external intervention. Even when our understanding of certain pivotal concepts has lapsed locally, our larger body of intuitions is sufficiently reliable to allow us, without intervention, to ferret out the modal errors resulting from this lapse of understanding by means of dialectic and/or a process of a priori reflection. This source of modal error, and our capacity to overcome it, has wide-ranging implications for philosophical method - including, in particular, its promise for disarming skepticism about the classical method of intuition-driven investigation itself. Indeed, it is shown that skeptical accounts of modal error are ultimately self-defeating. (shrink)

Este artículo examina cómo la separabilidad y unidad mente-cuerpo resultan clave para poner de manifiesto lo inapropiado del “teatro cartesiano”, metáfora creada por Daniel Dennett para criticar la experiencia consciente unificada en Descartes. La primera sección introduce al problema de la separabilidad cartesiana. La segunda examina cómo mente y cuerpo, separables mediante lo concebible según Descartes, resultan ser cosas metafísicamente distintas. La tercera enfatiza como separables no implica separados. La última sección enfatiza el argumento de la dis-analogía del piloto y (...) el navío, y cómo, según el filósofo francés, aunque separables, mente y cuerpo son substancias estrechamente unidas, formando un ens per se. En vista de este, criticamos la metáfora del “teatro cartesiano” de Dennett: es imposible que la mente sea un espectador, puesto que la experiencia consciente ya es unificada e incluso somatizada. Notamos, por último, que pese a Dennett, hay investigadores de la Ciencia Cognitiva que coinciden con Descartes en relación con la estrecha unión mente-cuerpo, i.e., quienes defienden que la mente es encarnada, incrustada o incluso extendida.

El Realismo Científico Estándar sostiene el enfoque metafísico de que el mundo es como es independiente de la mente. Sin embargo, el presente artículo demuestra cómo esta postura es incompatible con todas las teorías no-eliminativistas sobre la mente, lo cual hace que la postura sea inconsistente, incompatible con la ciencia, elimina la consciencia, la intencionalidad, la causación mental y la ética. Se propone una tesis realista alternativa que conserva la idea de que el mundo en general es de la forma (...) que es, independiente de lo que pensemos sobre él, compatible con la mente como parte real del mundo. Este cambio restaura la posibilidad de consistencia, la mente, la consciencia, la intencionalidad, la ciencia y la ética. -/- Standard Scientific Realism holds the metaphysical view that the world is the way it is independent of the mind. However, this paper demonstrates how this view is incompatible with all non-eliminativist theories of mind, leading it to be inconsistent, incompatible with science, and eliminating consciousness, intentionality, mental causation and ethics. An alternative realist thesis is proposed which preserves the idea that generally the world is the way it is independent of what we think of it, compatible with mind as a real part of the world. This reform restores the possibility of consistency, mind, consciousness, intentionality, science and ethics, while at the same time preserving the theoretical advantages over non-realist competitors.

Descartes has a Clarity First epistemology: (i) Clarity is a primitive (indefinable) phenomenal quality: the appearance of truth. (ii) Clarity is prior to other qualities: obscurity, confusion, distinctness – are defined in terms of clarity; epistemic goods – reason to assent, rational inclination to assent, reliability, and knowledge – are explained by clarity. (This is the first of two companion entries; the sequel is called, "Descartes's Method for Achieving Knowledge.").

Physicalism, if it is to be a significant thesis, should differentiate itself from key metaphysical contenders which endorse the existence of platonic entities, emergent properties, Cartesian souls, angels, and God. Physicalism can never be true in worlds where things of these kinds exist. David Papineau, David Spurrett, and Barbara Montero have recently developed and defended two influential conceptions of physicalism. One is derived from a conception of the physical as the non-mentally-and-non-biologically identifiable. The other is derived from a conception of (...) the physical as the non-sui-generis-mental. The paper looks at the resources available to those conceptions, but argues that each is insufficient to yield a conception of physicalism that differentiates it from key anti-physicalist positions. According to these conceptions, if we lived in a world full of things that clearly cannot be physical, we would still live in a physical world. Thus, such conceptions of physicalism are of little theoretical interest. (shrink)

This paper introduces a modal epistemology that centers on inference to the best explanation (i.e. abduction). In introducing this abduction-centered modal epistemology, the paper has two main goals. First, it seeks to provide reasons for pursuing an abduction-centered modal epistemology by showing that this epistemology aids a popular stance on the mind-body problem and allows an appealing approach to modality. Second, the paper seeks to show that an abduction-centered modal epistemology can work by showing that abduction can establish claims about (...) necessity/possibility (i.e. modal claims)—where ‘necessity’ and ‘possibility’ denote metaphysical necessity and possibility, ways things may or may not have been given how they actually are.

In various arguments, Descartes relies on the principles that conceivability implies possibility and that inconceivability implies impossibility. Those principles are in tension with another Cartesian view about the source of modality, i.e. the doctrine of the free creation of eternal truths. In this paper, I develop a ‘two-modality’ interpretation of the doctrine of eternal truths which resolves the tension and I discuss how the resulting modal epistemology can still be relevant for the contemporary discussion.

Christopher Hill and Joseph Levine have argued that the conceivabilities involved in anti-materialist arguments are defeated as evidence of possibility. Their strategy assumes the following principle: the conceivability of a state of affairs S constitutes evidence for the possibility of S only if the possibility of S is the best explanation of the conceivability of S. So if there is a better explanation of the conceivability of S than its possibility, then the conceivability of S is thereby defeated as evidence (...) of possibility. Hill and Levine proceed to offer alternative explanations of these conceivabilities, concluding that these conceivabilities are thereby defeated as evidence. However, this strategy fails because their explanations generalize to all conceivability judgments concerning phenomenal states. Consequently, one could defend absolutely any theory of phenomenal states against conceivability arguments in just this way. This result conflicts with too many of our common sense beliefs about the evidential value of conceivability with respect to phenomenal states. The general moral is that the application of such principles of explanatory defeat is neither simple nor straightforward. (shrink)

This thesis evaluates and compares two versions of neutral monism, one developed by William James and the other by Bertrand Russell. Both argued against Cartesianism in favour of a "subjectless given" as the basic stuff which constitutes both mind and matter. My evaluation will demonstrate that James’s and Russell's supposedly neutral entities are not neutral as their exponents claim because they fail to satisfy important criteria set for a theory to be genuinely neutral. There are two fundamental elements within my (...) discussion of the neutral entities. Firstly, I shall demonstrate that although James's initial repudiation of dualistic epistemology of subject and object, knower and known, led him to avoid metaphysical dualism of mental and physical, in Cartesian sense, by committing him to the view that there is one kind of entity called "experience", his final analysis admitted an internal distinction within the supposedly simple neutral entities. I shall call this covert dualism. Accepting James’s radical empiricism as an archetype, Russell’s early commitment to neutral monism led him to assert three distinctive kinds of entities, sensation, image and unperceived, and was therefore not complete as that of James. In order to bring his theory in line with James, Russell, in his mature version, entirely repudiated the dualistic view of perception which, following Moore, he accepted, to reject idealism. Russell declared percept as the neutral entity, which is both mental and material at once. But by re-introducing epistemological dualism, as James did, Russell admitted that a percept is not simple but complete bundle of compresent qualities and relations. 1 shall argue that like James’ his theory also collapses into covert dualism. Secondly, I shall argue that to produce a genuinely explanatory theory of neutral entities James and Russell exploited science to justify their theories. In course of their analysis they produced various arguments which has been considered as circular. An attempt will be made to show that the apparent circularity of their analysis is really part of a sophisticated programme, now known as bootstrapping. The notion of a bootstrap strategy has recently been developed in philosophy of science, and suggests a way in which the same evidence can be used to generate both a general and specific hypothesis. The thesis is divided into eight chapters. Chapters one, two and four are largely exegetical and chronological, and discuss the development of neutral monism especially in James and Russell’s philosophy together with the general characteristics of the theory as distinguished from other theories explaining mind and matter. Chapters three, five and six critically analyse James’s and Russell’s versions respectively to show their theories collapse into covert dualism. In chapter seven we argue that the alleged circularities in their theory are non- viscious and their employment of a bootstrap strategy introduced a profound innovation in epistemology. (shrink)

Descartes contends that he, or his mind, is really distinct from his body. Many philosophers have little patience with this claim. What could be more obvious than that the mind depends on the body? But their impatience often dissolves when they recognize that Descartes only asserts a de re modal statement. To say that one thing is really distinct from another is to say that each can exist apart from the other. But should we grant Descartes this de re modal (...) claim itself?Descartes's argument for the real distinction is based on the assumption that clear and distinct conception provides a reliable guide to possibility.

Cet article s’oppose à l’idée répandue selon laquelle notre conception de la personne est purement mentale. J’utilise l’un des scénarios imaginés par Anscombe, selon lequel les descriptions que nous faisons de nos propres actions sont tirées de l’observation. Je soutiens que si nous sommes, pour ainsi dire, comme un pilote dans son navire, nous ne sommes pas en mesure de nous attribuer à nous-mêmes des propriétés corporelles. Le seul fait de se sentir dans un corps, à la différence du pilote (...) dans son navire, ne peut produire l’intuition que nous sommes corporels. Tant que nous nous concevons comme des êtres mentaux, le fait que nous soyons des êtres corporels demeure un mystère inexplicable. (shrink)
