This is the first book-length study of Descartes's metaphysics to place it in its immediate historical context, the Late Scholastic philosophy of thinkers such as Suárez against which Descartes reacted. Jorge Secada views Cartesian philosophy as an 'essentialist' reply to the 'existentialism' of the School, and his discussion includes careful analyses and original interpretations of such central Cartesian themes as the role of scepticism, intentionality and the doctrine of the material falsity of ideas, universals and the relation between (...) sense and understanding, causation and the proofs of the existence of God, the theory of substance, and the dualism of mind and matter. His study offers a picture of Descartes's metaphysics that is both novel and philosophically illuminating. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 127-128 [Access article in PDF] Dennis Des Chene. Life's Form: Late Aristotelian Conceptions of the Soul. Ithaca, NY: Cornell University Press, 2000. Pp. viii + 220. Cloth, $45.00. The history of philosophy aims at the recovery and interpretation of past thought, and its reconstructions seek to avoid anachronism. Dennis Des Chene's book is exemplary in this respect. It offers a sophisticated (...) and accurate report on Late Scholastic views and arguments about life and its form and principle, the soul. It is full of subtle and informed discussions of texts from, principally, Francisco Toledo, Pedro Fonseca, the commentators from Coimbra, Francisco Suárez, and Rodrigo de Arriaga.But the aim of the history of philosophy is philosophical and not exclusively historical. Recovery of the past is, for the historian of philosophy, at the service of contemporary understanding. The Late Scholastic authors studied by Des Chene understood this to be so. Suárez, for instance, distinguished between those doctrines and inquiries which are "antiquated (antiquatae) and wholly relegated from philosophy" and those which are not (Metaphysical Disputations, "Copious Index to Aristotle's Metaphysics," Book I, ch. 7). Unfortunately, when judged from this perspective, Des Chene's book is not as successful.In spite of its many comparisons between current debates, Descartes's views, and Late Scholastic doctrines, the book does not succeed in extracting much by way of genuine philosophical insight. Though well-informed and intelligent, for the most part these glosses are mere statements of Late Scholastic views in contemporary terms. But correctly describing alchemical theories from the point of view of modern chemistry does not make them any less archaic.This book is indeed more a contribution to the history of ideas or of science than to the history of philosophy. To be fair, it is true that, first, as such it is a most valuable contribution; second, much of what Late Scholastics had to say about life and the soul is indeed antiquated; third, even if philosophically antiquated, an adequate grasp of Late Aristotelian thought on these matters is necessary to understand Descartes and subsequent developments; and finally, the kind of informed historical recovery that Des Chene has provided here is a necessary condition for whatever philosophical lessons could be gained from these texts.Life's Form is divided into four parts. The first, "Data for the Study of Souls," looks at the phenomena which the Late Aristotelians sought to understand and explain, recovering both their grasp of the place of the living among other substances, and the constraints, [End Page 127] originating both from accumulated experience and from Christian faith, to which they were subject.The second part, "Defining the Soul," first examines the question of how to define life. It then looks at the definition of the soul as "first act of an organic or potentially living physical body"—whether the soul is an accident of the body, an entirely separate substance, or the substantial form of the body. Here one finds addressed the question whether there is a form of the body separate from the soul, or whether strictly the body has only one form, the soul. The issue of cadaveric forms, peculiar forms of corpses arising after death and the departure of the soul, comes up here. In the last section of this part Des Chene examines the definition of the soul as a principle of life and the relation, both epistemological and ontological, between this definition in terms of the operations of the soul, and the earlier one of the soul as form, that is, in terms of its being.Part 3, "Powers and Parts," looks at the vegetative (nutritive, reproductive, and augmentative), animal (sensitive), and spiritual (intellective) powers of the soul. Des Chene examines the criteria for distinguishing between powers, the relation between the one soul and its many powers, and the unity of the soul. "Unity," the fourth part of the book, takes up this last topic. It looks at the vegetative, sensitive, and intellectual powers as "parts" of the... (shrink)

A discussion of Suarez's views on continuous quantity in the context of his place in the history of philosophy. The paper raises issues about conceptual change in intellectual history. It advances original interpretations of Aristotle and Suarez on continuous quantity.

This is a discussion of the moral psychology of monstrous evil. It suggests that deliberate monstrously evil acts committed in the name of the good by moral agents arises from a peculiar vice which blinds them to the humanity of others. It also examines an opposing virtue, generosity.

Descartes escribió que "no debemos nunca preguntar si algo existe al menos que ya conozcamos que es". Los comentaristas le han prestado poca atención a esta doctrina. Se trata, sin embargo, de una pieza medular en la metafísica cartesiana. Además, contiene una clave para la comprensión de las relaciones filosóficas entre Descartes y sus predecesores escolásticos. Este trabajo articula la doctrina esencialista de Descartes, contrastándola con el existencialismo de los aristotélicos. Finalmente, el trabajo respondeafirmativamente a la pregunta, ¿le fue fiel (...)

In this chapter, we discuss a selection of current views of the neural correlates of consciousness (NCC). We focus on the different predictions they make, in particular with respect to the role of prefrontal cortex (PFC) during visual experiences, which is an area of critical interest and some source of contention. Our discussion of these views focuses on the level of functional anatomy, rather than at the neuronal circuitry level. We take this approach because we currently understand more about experimental (...) evidence at this coarse level and because these results are appropriate for arbitrating between current theoretical frameworks. We discuss the Two-Visual-Systems Hypothesis (Milner & Goodale 1995; 2006), Local Recurrency (Lamme 2010; Lamme 2006), Higher Order (Lau 2008; Lau & Rosenthal 2011) and Global Workspace theories (Baars 1997; Baars 2005; Dehaene & Naccache 2001; Dehaene 2014). Despite the apparent stark differences between conscious and unconscious perceptual processing, available evidence suggests that their neural substrates must be largely shared. This indicates that the difference in neural activity between conscious and unconscious perceptual processing is likely to be subtle and highly specialized. We argue that current experimental evidence about the involvement of specific activity in prefrontal cortex supports the higher order neural theory of consciousness. In consequence, imaging techniques that focus only on marked differences between conscious and unconscious level of activity are likely to be insensitive to the relevant neural activity patterns that underlie conscious experiences. Finally, it follows from the evidence we discuss that the functional advantages of conscious over unconscious perceptual processing may be more limited than commonly thought. (shrink)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

Martin Buber believed that life's deepest truth lies in human relationships. In this classic work he puts this belief into practice, applying it to the concrete problems of contemporary society.

Metacognition is the capacity to evaluate the success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that is applied to different tasks or if self-evaluative processes are domain specific. Here, we investigated this issue directly by examining the neural substrates engaged when metacognitive judgments were made by human participants of both sexes during perceptual and memory tasks matched for stimulus and performance characteristics. By comparing patterns (...) of fMRI activity while subjects evaluated their performance, we revealed both domain-specific and domain-general metacognitive representations. Multivoxel activity patterns in anterior prefrontal cortex predicted levels of confidence in a domain-specific fashion, whereas domain-general signals predicting confidence and accuracy were found in a widespread network in the frontal and posterior midline. The demonstration of domain-specific metacognitive representations suggests the presence of a content-rich mechanism available to introspection and cognitive control. (shrink)

Studying the neural correlates of conscious awareness depends on a reliable comparison between activations associated with awareness and unawareness. One particularly difficult confound to remove is task performance capacity, i.e. the difference in performance between the conditions of interest. While ideally task performance capacity should be matched across different conditions, this is difficult to achieve experimentally. However, differences in performance could theoretically be corrected for mathematically. One such proposal is found in a recent paper by Lamy, Salti and Bar-Haim [Lamy (...) D, Salti M, Bar-Haim Y. Neural correlates of subjective awareness and unconscious processing: an ERP study. J Cognitive Neurosci 2009,21:1435-46], who put forward a corrective method for an electroencephalography experiment. We argue that their analysis is essentially grounded in a version of High Threshold Theory, which has been shown to be inferior in general to Signal Detection Theory. We show through a series of computer simulations that their correction method only partially removes the influence of perfor- mance capacity, which can yield misleading results. We present a mathematical correction method based on Signal Detection Theory that is theoretically capable of removing performance capacity confounds. We discuss the limitations of mathemati- cally correcting for performance capacity confounds in imaging studies and its impact for theories about consciousness. (shrink)

Implementing corporate social responsibility (CSR) in supply chains is not a trivial task. In fact, many firms in recent years have publicly proclaimed that in order to keep their CSR commitments, they had to reduce reliance on external suppliers by vertically integrating their operations. Our aim in this article is to examine whether there is truly a relationship between a firm’s CSR performance and its level of vertical integration. Drawing on a multi-industry sample of 2,715 firm-year observations, and after addressing (...) endogeneity concerns, we demonstrate that firms with higher CSR performance tend to vertically integrate more (or, outsource less). We also demonstrate that this tendency is weaker for firms that have higher degrees of asset specificity or international diversification. Our core conclusion is that CSR performance and outsourcing are at odds, but firms can reconcile this tension by deepening their collaborations with suppliers. (shrink)

We prove that in many situations it is consistent with ZFC that part of the invariants involved in Cichon's diagram are equal to κ while the others are equal to λ, where $\kappa < \lambda$ are both arbitrary regular uncountable cardinals. We extend some of these results to the case when λ is singular. We also show that $\mathrm{cf}(\kappa_U(\mathscr{L})) < \kappa_A(\mathscr{M})$ is consistent with ZFC.

Consciousness and confidence seem intimately related. Accordingly, some researchers use confidence ratings as a measure of, or proxy for, consciousness. Rosenthal discusses the potential connections between the two, and rejects confidence as a valid measure of consciousness. He argues that there are better alternatives to get at conscious experiences such as direct subjective reports of awareness (i.e. subjects’ reports of perceiving something or of the degree of visibility of a stimulus). In this chapter, we offer a different perspective. Confidence ratings (...) in general, and metacognitive measures in particular, may offer important advantages over subjective ratings. The arguments we offer here are supported by empirical, practical and socio-strategic considerations. However, we do not suggest consciousness and confidence are interchangeable. We recognize the limitations of confidence ratings in some experimental designs and for some research questions. Nevertheless, we also address a potential conceptual link between consciousness and confidence that stems from Rosenthal’s very own work on mental quality space theory. (shrink)

Following the Enlightenment, the concept of ‘critique’ broadened and acquired a political denotation, in which the expression of opinion alone could itself be already considered critique. This meaning of ‘critique’ expresses acknowledgement of men as equal, free and rational. This broad concept of critique, however, also tends to negate certain more technical and specific forms. This paper goes back to conceptions of critique introduced by Kant and developed in an educational perspective by the neo-Kantian Paul Natorp. Kant's concept of critique (...) concentrated on the conditions of possibility of judgemental powers, resulting in a transcendental critique of Reason. Natorp applied this conception of transcendental critique to education. Though Natorp relates education to society as a whole, his concept of critique does not uncover the social determinants of educational views but holds on to a transcendental critical idea of critical judgement that is not completely socially determined. Consequently, in the transcendental critical approach, the critical function of Reason is given priority over any political vision. This results in a conception of critique that primarily questions validity claims, stressing rational testing as opposed to other sources of validity, such as traditional or religious authority. The transcendental critical programme, further developed in twentieth-century Germany, still endorses the implied denial of the possibility of deriving the validity of propositions from experience. It can be distinguished from Karl-Otto Apel's brand of transcendental critique by its refusal to assume any primary criterion for critical judgement, in the manner of Apel's ‘ideal communicative community’. Consequently, this programme cannot result in any positive conception of education. Its main contribution consists in exposing those presuppositions of educational views and practices that function as a priori ideas as conditions of the possibility of their justification. Though not denying the value and relevance of positive educational conceptions, this transcendental critical approach primarily aims at preventing metaphysical foundational questions from being forgotten or dogmatically fossilised.

To find the neural substrates of consciousness, researchers compare subjects’ neural activity when they are aware of stimuli against neural activity when they are not aware. Ideally, to guarantee that the neural substrates of consciousness—and nothing but the neural substrates of consciousness—are isolated, the only difference between these two contrast conditions should be conscious awareness. Nevertheless, in practice, it is quite challenging to eliminate confounds and irrelevant differences between conscious and unconscious conditions. In particular, there is an often-neglected confound that (...) is crucial to eliminate from neuroimaging studies: task performance. Unless subjects’ task performance is matched (and hence perceptual signal processing is matched), researchers risk finding the neural correlates of perception, rather than conscious perception. Here, we discuss the theoretical motivations for the performance matching framework and review empirical demonstrations of, and theoretical inferences derived from, obtaining differences in consciousness while controlling for task performance. We summarize signal detection theoretic modeling frameworks that explain how it is that we can derive performance-matched differences in consciousness without the effect being trivially driven by differences in criterion setting, and also provide principles for designing experimental paradigms that yield performance-matched differences in awareness. Finally, we address potential technical and theoretical issues that stem from matching performance across conditions of awareness, and we introduce the notion of “triangulation” for designing comprehensive experimental sets that can better reveal the neural substrates of consciousness.

In this paper, I reject that animal reasoning, negation in particular, necessarily involves the representation of absences, as suggested by Bermúdez (2003, 2006, 2007), since this would still work as a logical negation (unavailable for non-linguistic creatures). False belief, pretense, and communication experiments show that non-human animals (at least some primates) have difficulties representing absent entities or properties. I offer an alternative account resorting to the sub-symbolic similarity judgments proposed by Vigo & Allen (2009) and expectations: animal proto-negation takes place (...) through the incompatibility between an expected and the actual representation. Finally, I propose that the expectation paradigm be extrapolated to other experi-ments in cognitive psychology (both with pre-linguistic children and animals) in order to design fair experiments that test other minds considering their true abilities.
