Descartes was born in La Haye (now Descartes) in Touraine and educated at the Jesuit college of La Fleche` in Anjou. Descartes’modern reputation as a rationalistic armchair philosopher, whose mind–body dualism is the source of damaging divisions between psychology and the life sciences, is almost entirely undeserved. Some 90% of his surviving correspondence is on mathematics and scientific matters, from acoustics and hydrostatics to chemistry and the practical problems of constructing scientific instruments. Descartes was just as interested in the motions (...) of matter as in the supernatural soul, and he advised against spending too much time on metaphysical inquiries which neglect imagination and the senses. After meeting the Dutch engineer Isaac Beeckman in 1618, Descartes became committed to a systematically ‘mechanical’account of nature. This involved explaining all natural processes in terms of interactions between microscopic material bodies in motion. Descartes modelled his physics and cosmology on the behaviour of fluids, which also have a distinctive and central role in his physiology: the key processes for natural philosophical investigation are the circulation and mutual displacement of constrained bodies, rather than the isolated collisions of atoms in a void. Descartes settled in Holland in 1628, and commenced an ambitious programme of physiological research. In 1630 he was ‘studying chemistry and anatomy simultaneously’, and in late 1632 he was ‘dissecting the heads of various animals’, in order to ‘explain what imagination, memory, etc. consist in’. By late 1633 Descartes had almost completed L’homme, the Treatise on Man; but he abandoned plans to publish it along with a work on matter theory and optics which relied on Copernican cosmology, after he heard of the condemnation of Galileo. L’homme was published posthumously in 1662 (Latin) and 1664 (French); not until 1972 was it fully translated into English. L’homme draws on many (mostly unnamed) Renaissance medical writers, and covers, firstly, a range of traditional physiological topics, such as digestion and respiration.. (shrink)

A fully adequate solution to Newcomb’s Problem (Nozick 1969) should reveal the source of its extraordinary elusiveness and persistent intractability. Recently, a few accounts have independently sought to meet this criterion of adequacy by exposing the underlying source of the problem’s profound puzzlement. Thus, Sorensen (1987), Slezak (1998), Priest (2002) and Maitzen and Wilson (2003) share the ‘no box’ view according to which the very idea that there is a right choice is misconceived since the problem is ill-formed or incoherent (...) in some way. Among proponents of this view, Richard Jeffrey (2004) recently declared that he renounces his earlier position that accepted Newcomb problems as genuine decision problems. Significantly, Jeffrey suggests that “Newcomb problems are like Escher’s famous staircase on which an unbroken ascent takes you back where you started” (Jeffrey (2004; 113)). Jeffrey’s analogy is apt for a puzzle whose specific logical features can be precisely articulated. Along the lines of these related approaches, I propose to improve and clarify them by providing such a deeper analysis that elucidates their essential, related insights. (shrink)

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly (...) different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

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.").

In this paper, I have made an attempt to understand the concept of moral certainty in Descartes’ philosophy. This concept has not received much attention in the Cartesian scholarship. I argue that Descartes entertains a certainty, called moral certainty, which is a lesser certainty than metaphysical certainty, which we see in his text, Meditations. Only a few Cartesian scholars have talked about this concept in relation to other areas in Descartes’ philosophy. In this paper, I draw a relationship between the (...) concept of moral certainty and the faculty of reason in the context of Descartes’ text, Discourse. I argue that Descartes entertains the testimonies of learned men when it comes to practical or moral matters, arguing that their testimonies guarantee moral certainty. I argue that Descartes claims, in the Discourse, that human beings are endowed with the faculty of reason on the basis of moral certainty. (shrink)

This thesis develops a novel framework for explaining delusions. In Chapter 1, I introduce the two fundamental challenges posed by delusions: the evidence challenge lies in explaining the flagrant ways delusions flout evidence; and the specificity challenge lies in explaining the fact that patients’ delusions are often about a few specific themes, and patients rarely have a wide range of delusional or odd beliefs. In Chapter 2, I discuss the strengths and weaknesses of current theories of delusions, which typically appeal (...) to one or both of two factors: anomalous experience and reasoning abnormality. I argue that anomalous experience can help explain the specificity of delusions, but has difficulties in addressing the evidence challenge; reasoning abnormality can help address the evidence challenge, but has difficulties in explaining the specificity of delusions. This suggests that there may be an important factor that has not been captured by current theories of delusions. To search for this missing factor, in Chapter 3, I turn to normal believing. Inspired by the literature on Cartesian clarity and phenomenal dogmatism, I develop a dual-force framework of believing, according to which beliefs can be understood as the results of the interaction between the justificatory force and causal force of evidence and the justificatory force and causal force of clear experience, in which something clearly seems to be so to the subject. This framework suggests that the missing factor may be the clear experience with its distinctive phenomenal clarity that compels assent. In Chapter 4, I return to delusions, and argue that the dualforce framework can help us to get a better grip on some personal descriptions of delusions; make progress in addressing the evidence and specificity challenges of delusions; and shed new light on the underpinnings of delusions. In the end, I conclude with some remaining questions for future study. (shrink)

In this paper, I reflect on Descartes' employment of the meditational genre in the weaving of the text of the Meditations. In the first part, the possible influences behind Descartes' choice of the meditational genre are examined. The second part of the paper attempts to spell out the significance of Descartes' use of the meditational form. The claim advanced here is that Descartes adopted this unique genre ultimately to further his radical philosophical project of a subject-centred theory of knowledge and (...) a new metaphysical Weltbild, with the self catapulted to the central stage and the physical world reduced to an object of the subject's act of representation.

This Master of Arts thesis is in two parts: a novel, An Anarchy of Man, and an exegesis which places the novel in relation to philosophical concerns about the self and the way those concerns are portrayed in selected works of Western literature. The novel is set in Canberra and Sydney and tells the story of the relationship between two characters: Joe and Gin. It explores the way we in the modern Western world think about ourselves and those around us. (...) Chapter One considers the view of the self in the work of the philosopher Rene Descartes and explores how this view is portrayed in three contemporary Australia novels, and in An Anarchy of Man. Chapter Two examines post-Cartesian views of the self, especially those in the work of the philosopher Ludwig Wittgenstein, and then considers the way the self is portrayed in Proust's Remembrance of Things Past, and in my own An Anarchy of Man. Chapter Three examines postmodern conceptions of the self and considers how these conceptions are portrayed in the work of the contemporary American novelist Don DeLillo and in my own An Anarchy of Man.

Let me begin with what may seem a very minor point, but one which I think reveals something about how many philosophers today conceive of their subject. During the past few decades, there has been an increasing tendency for references in philosophy books and articles to be formatted in the ‘author and date’ style (‘see Fodor (1996)’, ‘see Smith (2001)’.) A neat and economical reference system, you may think; and it certainly saves space, albeit inconveniencing readers by forcing them to (...) flip back to the end of the chapter or book to find the title of the work being referred to. But what has made this system so popular among philosophers? A factor which I suspect exerts a strong subconscious attraction for many people is that it makes a philosophy article look very like a piece of scientific research. For if one asks where the ‘author-date’ system originated, the answer is clear: it comes from the science journals. And in that context, the choice of referencing system has a very definite rationale. In the progress-driven world of science, priority is everything, and it's vitally important for a career that a researcher is able to proclaim his work as breaking new ground. Bloggs (2005) developed a technique for cloning a certain virus; Coggs (2006) showed how certain bits of viral DNA could be spliced; and now Dobbs (2007) draws on both techniques to develop the building blocks of a new vaccine. The idea is that our knowledge-base is enhanced, month by month and year by year, in small incremental steps (perhaps with occasional major breakthroughs); and in the catalogue of advances, the date tagged to each name signals when progress was made, and by whom.

ABSTRACT Latin American decolonial theory is built around the thesis of the “coloniality of knowledge”, which claims that the socio-political domination of Latin America and other regions of the global periphery by European countries and the United States is directly related to the initial colonial imposition and subsequent cultural reproduction of so-called “Western epistemology” and science. I argue that the epistemological claims of four decolonial thinkers that make up the coloniality of knowledge thesis are problematic for several reasons: they are (...) based on distorted and simplistic readings of Descartes, Hume and other Enlightenment figures; they make contentious generalizations about so-called Western epistemology; and they ultimately lead to epistemic relativism, which is a problematic basis for the social sciences and, contrary to decolonial aspirations, renders the subaltern unable to speak.

Argues that Descartes's commitment to mind-body causation leads to a commitment to body-body causation.

This article models a critical method of engaging with not-knowing as it relates to discourses around sexual agency and sexual violation through an analysis of Carmen Maria Machado’s short story ‘The Husband Stitch’. I argue that sexual and gender-based violation not only enforces harmful forms of uncertainty among the women of the story. It also forecloses the potentially productive capacities of modes of not-knowing. In doing so, I respond to assertions from feminist scholars as varied Linda Martín Alcoff, Mary Gaitskill, (...) Laura Kipnis and Joseph Fischel that we need to better account for the full ‘complexity’ of narratives of sexual encounter – including violent encounters. Broadly, in a #MeToo era in which stories of sexual and gender-based violence have received unprecedented mainstream public exposure, I contend that we can both treat the testimonies of survivors as credible and authoritative, and open up discursive space for the experience and expression of not-knowing.

In this paper I consider the relation between Descartes' psychology of vision and the cognitive science approach to psychology (henceforth CS). In particular, I examine Descartes' the Optics (1637) in the light of David Marr's (1982) position in CS. My general claim is that CS can be seen as a rediscovery of Descartes' psychology of vision. In the first section, I point to a parallel between Descartes' epistemological revolution, which created the modem version of the problem of perception, and the (...) cognitive revolution. These fundamental revolutions in theoretical psychology were both inspired and legitimated by a revolution in mathematics. They took place in accordance with one of Marr's maxims: “To the desirable via the possible”. In the second section, I demonstrate that in the Optics, Descartes explains perception of metrical properties in a way that — on a detailed level — is in accordance with how Man argues that complex information processing systems have to be explained: both Descartes and Man emphasize the co-ordination of logical and physical analysis. In the third section, I claim that Descartes' arguments for a sharp distinction between mechanical transmission of sense data (sensation) and non-mechanical inferences on those sense data (thinking) are sound arguments seen from Man's position in CS. Descartes' arguments are based on his logical and physical analysis. Malebranche's radicalized version of Cartesian dualism turns Descartes' empirically-based assumption that mechanisms cannot realize inferences into a metaphysical assumption. In the final section, I argue that this metaphysical assumption contributes to an understanding of perception as a non-symbolic, non-inferential bottom-up process in mainstream monistic and mechanistic scientific psychology until the cognitive revolution.
