In Tulving’s initial characterization, episodic memory was one of multiple memory systems. It was postulated, in pursuit of explanatory depth, as displaying proprietary operations, representations, and substrates such as to explain a range of cognitive, behavioural, and experiential phenomena. Yet the subsequent development of this research program has, paradoxically, introduced surprising doubts about the nature, and indeed existence, of episodic memory. On dominant versions of the ‘common system’ view, on which a single simulation system underlies both remembering and imagining, there (...) are no processes unique to memory to support robust generalizations with inductive potential. Eliminativism about episodic memory seems to follow from the claim that it has no dedicated neurocognitive system of its own. After identifying this under-noticed threat, we push back against modern eliminativists by surveying recent evidence that still indicates specialized mechanisms, computations, and representations that are distinctly mnemic in character. We argue that contemporary realists about episodic memory can retain lessons of the common system approach while resisting the further move to eliminativism. (shrink)

Researchers recently demonstrated a strong direct relationship between judgments about what a person knows and judgments about how a person should act. But it remains unknown whether actionability judgments cause knowledge judgments, or knowledge judgments cause actionability judgments. This paper uses causal modeling to help answer this question. Across two experiments, we found evidence that actionability judgments cause knowledge judgments.

If the contents of our thoughts are partly determined by facts outside our heads, can we still know those contents directly, without investigating our environment? What if we were surreptitiously switched to Twin-Earth? Would we know the contents of our thoughts under these unusual circumstances? By looking carefully at what determines the content of a second-order thought, a candidate for self-knowledge, the paper argues that we can know the contents of our thoughts directly, even after being switched. Learning about the (...) switch, however, does raise some interesting difficulties. (shrink)

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two (...) factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

Recent work has shown that knowledge attributions affect how people think others should behave, more so than belief attributions do. This paper reports two experiments providing evidence that knowledge attributions also affect behavioral predictions more strongly than belief attributions do, and knowledge attributions facilitate faster behavioral predictions than belief attributions do. Thus, knowledge attributions play multiple critical roles in social cognition, guiding judgments about how people should and will behave.

This paper addresses the foundations of Teleological Individualism, the view that organisms, even non-sentient organisms, are goal-oriented systems while biological collectives, such as ecosystems or conspecific groups, are mere assemblages of organisms. Typical defenses of Teleological Individualism ground the teleological organization of organisms in the workings of natural selection. This paper shows that grounding teleological organization in natural selection is antithetical to Teleological Individualism because such views assume a view about the units of selection on which it is only individual (...) organisms that are units of selection. However, none of the Conventionalist, Reductionist, or Multi-Level Realist theories serve to justify such an assumption. Thus, Teleological Individualism cannot be grounded in natural selection.

The A-theory and the B-theory advance competing claims about how time is grounded. The A-theory says that A-facts are more fundamental in grounding time than are B-facts, and the B-theory says the reverse. We argue that whichever theory is true of the actual world is also true of all possible worlds containing time. We do this by arguing that time is uniquely groundable: however time is actually grounded, it is necessarily grounded in that way. It follows that if either the (...) A-theory or the B-theory is actually false, then it is necessarily false. (shrink)

According to several authors, the enhancement project incorporates a quest for hyperagency - i.e. a state of affairs in which virtually every constitutive aspect of agency (beliefs, desires, moods, dispositions and so forth) is subject to our control and manipulation. This quest, it is claimed, undermines the conditions for a meaningful and worthwhile life. Thus, the enhancement project ought to be forestalled or rejected. How credible is this objection? In this article, I argue: “not very”. I do so by evaluating (...) four different versions of the “hyperagency” objection from four different authors. In each case I argue that the objection either fails outright or, at best, provides weak and defeasible grounds for avoiding enhancement. In addition to this, I argue that there are plausible grounds for thinking that enhancement helps, rather than hinders, us in living the good life. (shrink)

I start with a brief assessment of the implications of Sterelny’s anti-individualist, anti-internalist apprentice learning model for a more historical and interdisciplinary cognitive science. In a selective response I then focus on two core features of his constructive account: collaboration and skill. While affirming the centrality of joint action and decision making, I raise some concerns about the fragility of the conditions under which collaborative cognition brings benefits. I then assess Sterelny’s view of skill acquisition and performance, which runs counter (...) to dominant theories that stress the automaticity of skill. I suggest that it may still overestimate the need for and ability of experts to decompose and represent the elements of their own practical knowledge. (shrink)

A woman is listening to Sinatra before work. As she later describes it, ‘suddenly from nowhere I could hear my mother singing along to it … I was there again home again, hearing my mother … God knows why I should choose to remember that … then, to actually hear her and I had this image in my head … of being at home … with her singing away … like being transported back you know I got one of those (...) … like shivery feelings really suddenly’ (Anderson 2004, 9-10). An older couple, discussing their honeymoon forty years ago, each say that they can’t remember the show they saw, until through iterative, puzzled cross-cuing they finally get there – ‘Desert Song, that’s it’ (Harris et al 2011, 292). An elderly English veteran of a prisoner of war camp in Japan, finishing up morning tea with a young Japanese social scientist interested in reconciliation, suddenly calls out loudly - in Japanese - ‘stand to attention’. He stands to attention in front of her: like many of the men she interviews, he physically re-enacts fragments of that long-past world of the camp, bringing that absent past into this new present context with a visceral shock (Murakami 2001, 2012; Middleton & Brown 2005, 133-136).

The journal of Cognitive Computation is defined in part by the notion that biologically inspired computational accounts are at the heart of cognitive processes in both natural and artificial systems. Many studies of various important aspects of cognition (memory, observational learning, decision making, reward prediction learning, attention control, etc.) have been made by modelling the various experimental results using ever-more sophisticated computer programs. In this manner progressive inroads have been made into gaining a better understanding of the many components of (...) cognition. Concomitantly in both science and science fiction the hope is periodically re-ignited that a manmade system can be engineered to be fully cognitive and conscious purely in virtue of its execution of an appropriate computer program. However, whilst the usefulness of the computational metaphor in many areas of psychology and neuroscience is clear, it has not gone unchallenged and in this article I will review a group of philosophical arguments that suggest either such unequivocal optimism in computationalism is misplaced—computation is neither necessary nor sufficient for cognition—or panpsychism (the belief that the physical universe is fundamentally composed of elements each of which is conscious) is true. I conclude by highlighting an alternative metaphor for cognitive processes based on communication and interaction. (shrink)

Leading virtue epistemologists defend the view that knowledge must proceed from intellectual virtue and they understand virtues either as refned character traits cultivated by the agent over time through deliberate effort, or as reliable cognitive abilities. Philosophical situationists argue that results from empirical psychology should make us doubt that we have either sort of epistemic virtue, thereby discrediting virtue epistemology’s empirical adequacy. I evaluate this situationist challenge and outline a successor to virtue epistemology: abilism . Abilism delivers all the main (...) benefts of virtue epistemology and is as empirically adequate as any theory in philosophy or the social sciences could hope to be. (shrink)

A philosopher once wrote the following words:If I examine the PTOLOMAIC and COPERNICAN systems, I endeavour only, by my enquiries, to know the real situation of the planets; that is, in other words, I endeavour to give them, in my conception, the same relations, that they bear towards each other in the heavens. To this operation of the mind, therefore, there seems to be always a real, though often an unknown standard, in the nature of things; nor is truth or (...) falsehood variable by the various apprehensions of mankind. Though all human race should for ever conclude, that the sun moves, and the earth remains at rest, the sun stirs not an inch from his place for all these reasonings; and such conclusions are eternally false and erroneous.

Our environmental wrongdoings result in a moral debt that requires restitution. One component of restitution is reparative and another is remediative. The remediative component requires that we remediate our characters in ways that alter or eliminate the character traits that tend to lead, in their expression, to environmental wrongdoing. Restitutive restoration is a way of engaging in ecological restoration that helps to meet the remediative requirement that accompanies environmental wrongdoing. This account of restoration provides a new motivation and justification for (...) engaging in restorative practices in addition to the standard pragmatist justification and motivations. (shrink)

Schemes of diagrammatic representation have been so familiarly introduced into logical treatises during the last century or so, that many readers, even of those who have made no professional study of logic, may be supposed to be acquainted with the general nature and object of such devices. Of these schemes one only, viz. that commonly called "Eulerian circles," has met with any general acceptance. A variety of others indeed have been proposed by ingenious and celebrated logicians, several of which would (...) claim notice in a historical treatment of the subject; but they mostly do not seem to me to differ in any essential respect from that of Euler. They rest upon the same leading principle, and are subject all alike to the same restrictions and defects. We must therefore cast about for some new scheme of diagrammatic representation which shall be competent to indicate imperfect knowledge on our part; for this will at once enable us to appeal to it step by step in the process of working out our conclusions. I have never seen any hint at such a scheme, though the want seems so evident that one would suppose that something of the kind must have been proposed before. (shrink)

The argument presented in this paper is not a direct attack or defence of the Chinese Room Argument (CRA), but relates to the premise at its heart, that syntax is not sufficient for semantics, via the closely associated propositions that semantics is not intrinsic to syntax and that syntax is not intrinsic to physics. However, in contrast to the CRA’s critique of the link between syntax and semantics, this paper will explore the associated link between syntax and physics. The main (...) argument presented here is not significantly original – it is a simple reflection upon that originally given by Hilary Putnam (Putnam 1988) and criticised by David Chalmers and others: instead of seeking to justify Putnam’s claim that, “every open system implements every Finite State Automaton (FSA)”, and hence that psychological states of the brain cannot be functional states of a computer, I will seek to establish the weaker result that, over a finite time window every open system implements the trace of a particular FSA Q, as it executes program (p) on input (x). That this result leads to panpsychism is clear as, equating Q (p, x) to a specific Strong AI program that is claimed to instantiate phenomenal states as it executes, and following Putnam’s procedure, identical computational (and ex hypothesi phenomenal) states (ubiquitous little ‘pixies’) can be found in every open physical system.

The “shrinking” of the globe in the last few centuries has made explicit that the world is a tense unity of many: the many worlds are forced to contend with one another. Nishida Kitarō, the founder of the Kyoto school, once stated that to be is to be implaced. We exist by partaking in “the socio-historical world.” More recently, Jean-luc Nancy has conceived of the world in terms of sense. What is striking in both is that the world emerges out (...) of a nothing, created ex nihilo—the phrase stripped of its theistic connotations. While for Nishida the world is ultimately implaced in the “place of absolute nothing,” Nancy speaks of the nothing that is the basis of the world’s self-creation. I will explore a possible convergence between these and any light it may shed upon our contemporary situation of globalization and its implications for praxis. I look to a sense of the nothing as a chōratic spatiality, an opening that provides space for co-being and serves as the source of creativity. In face of globalization, the project for meaning through mondialisation (in Nancy) and within a multi-cultural world (in Nishida) would imply the appropriation of such an originary spatiality.

Aquinas’s Fifth Way is usually taken to be an adumbration of Paley-like design arguments. Paley-like design arguments have fallen on hard times over the past few centuries, and most contemporary defenders of design arguments in support of theism favor some version of the fine-tuning argument. But fine-tuning designarguments, like Paley’s design argument, are consistent with atomism. And all such arguments are vulnerable to the objection that, given a long enough stretch of time and a sufficient number of universes, there would (...) be no need to posit a designer. In this paper we argue that a deep understanding of Aquinas’s Fifth Way depends upon understanding his hylomorphic account of the nature of composite substance, an account that is inconsistent with atomism. We argue that if one grants hylomorphism, Aquinas’s Fifth Way is difficult to resist. And we defend Aquinas’s hylomorphism against several common objections. (shrink)

Statements containing epistemic modals (e.g., “by spring 2023 most European countries may have the Covid-19 pandemic under control”) are common expressions of epistemic uncertainty. In this paper, previous published findings (Knobe & Yalcin, 2014; Khoo & Phillips, 2018) on the opposition between Contextualism and Relativism for epistemic modals are re-examined. It is found that these findings contain a substantial degree of individual variation. To investigate whether participants differ in their interpretation of epistemic modals, an experiment with multiple phases and sessions (...) is used to classify participants according to the three semantic theories of Relativism, Contextualism, and Objectivism. Through this study, some of the first empirical evidence for the kind of truth-value shifts postulated by semantic Relativism is presented. It is furthermore found that participants’ disagreement judgments match their truth evaluations and that participants are capable of distinguishing between truth and justification. In a second experimental session, it is investigated whether participants thus classified follow the norm of retraction which Relativism uses to account for argumentation with epistemic modals. Here the results are less favorable for Relativism. In a second experiment, these results are replicated and the normative beliefs of participants concerning the norm of retraction are investigated following work on measuring norms by Bicchieri (2017). Again, it is found that on average participants show no strong preferences concerning the norm of retraction for epistemic modals. Yet, it was found that participants who had committed to Objectivism and had training in logics applied the norm of retraction to might-statements. These results present a substantial challenge to the account of argumentation with epistemic modals presented in MacFarlane (2014), as discussed. Keywords: Epistemic Modals, Relativism, Norm Conflicts, Retraction, Semantics, Truth Conditions, Argumentation. (shrink)

This essay consists of two parts. Part I offers an explanation of Berkeley's understanding of the relationship between materialism and evil. Berkeley regards materialism as the chief instrumental cause of evil in the world. It is the belief in matter that encourages us to believe that God is not immediately, intimately present in every aspect of our life. Immaterialism, by contrast, makes God's immediate presence vivid and thereby serves to undermine the motivation to vice. Part II locates Berkeley's view on (...) matter and evil within the Christian Neoplatonic tradition. I compare Plotinus' minimalist approach to matter and his identification of matter with evil to Berkeley's eliminitivism about matter and his corresponding identification of materialism as the chief source of evil.

What is an occurrent mental state? According to a common scholastic answer such a state is at least in part a quality of the mind. When I newly think about a machiatto, say, my mind acquires a new quality. However, according to a view discussed by John Buridan (who rejects it) and John of Mirecourt (who is condemned in 1347 for considering it “plausible”), an occurrent mental state is not even in part a quality. After sketching some of (...) the history of this position, I will present two common arguments against it—the argument from change and the argument from agency. I will then turn to Mirecourt’s own position on the matter. Mirecourt, I show, in fact offers us two different theories about occurrent mental states. The first, which I call the conservation theory, accepts that mental states are in part qualities. However, a mental state is a quality together with an action on the side of the mind, namely, its conservation of a quality within itself. The second position, which I will call the pure-action theory, holds that an occurrent mental state is not even in part a quality; instead, it is an action the mind performs which is neither the production nor the conservation of a quality within itself. Mirecourt characterizes such pure actions as “modes” of the mind, and it is this position which is condemned in 1347. In the final section, I turn to an objection that both Buridan and Mirecourt raise against the pure-action theory: if accidental states of the mind are mere modes of the mind, then why not suppose that all accidents are mere modes of the subjects which they qualify?

It is generally accepted that Mill’s classification of names as nonconnotative terms is incompatible with Frege’s thesis that names have senses. However, Milldescribed the senses of nonconnotative terms—without being aware that he was doing so. These are the senses for names that were sought in vain by Frege. When Mill’s and Frege’s doctrines are understood as complementary, they constitute a fully satisfactory theory of names.

Rachael Briggs and Daniel Nolan have recently proposed an improved version of Nozick’s tracking account of knowledge. I show that, despite its virtues, the new proposal suffers from three serious problems.

This issue of the Kybernetes journal is concerned with the philosophical question- Can a Machine Think? Famously, in his 1950 paper `Computing Machinery andIntelligence' [9], the British mathematician Alan Turing suggested replacing this question - which he found \too meaningless to deserve discussion" - with a simple -behavioural - test based on an imagined `Victorianesque' pastime he entitled the`imitation game'. In this special issue of Kybernetes a selection of authors with a special interest in Turing's work (including those who participated (...) in the 2008 AISB Turing Symposium) have been invited to explore and clarify issues arising from Turing's 1950 paper on the Imitation Game; now more widely known as the Turing test.

In the midst of even the most tragic circumstances attending the aftermath of disaster, and co-existing with a host of complex emotions, arises a practical consideration: how might similar tragedies be prevented in the future? The complexity of such situations must not be neglected. More than mere prevention must usually be taken into consideration. But the practical question is of considerable importance. In what follows, I will offer some reasons for being concerned that efforts to fix the problem -- efforts, (...) that is, directed toward insuring that similar tragedies do not occur in the future -- can easily be obstructed by attempts to fix blame -- that is, efforts directed toward determining which agent among those involved is guilty of wrong-doing. This is the case, I shall contend, even where some agent or another really is guilty of wrong-doing. The problem is further complicated by a pervasive human tendency to imagine that some agent or another must be responsible in some way for any tragedy that occurs -- even when this is not really true -- but its influence is not at all limited to such cases. As I shall suggest, philosophical attitudes toward issues of determinism and free will may be implicated in the different approaches people take to the problem of assessing what has gone wrong in a particular case and how to fix it, but such deep philosophical problems need not be resolved here. The point is not that humans are never guilty of wrong-doing (since their actions, the argument might go, are all products of outside forces), but rather that whatever the case may be about guilt, tracking down guilty persons is a different business from fixing institutionally-embedded problems so as to lessen the likelihood of their recurrence.

This chapter will explicate what Nishida means by “nothing” (mu, 無), as well as “being” (yū, 有), through an exposition of his concept of the “place of nothing” (mu no basho). We do so through an investigation of his exposition of “the place of nothing” vis-àvis the self, the world, and God, as it shows up in his epistemology, metaphysics, theology and religious ethics during the various periods of his oeuvre – in other words, his understanding of nothingness that he (...) takes to be the root of the self, the world, and the religious notion of an absolute or God. We will also indicate some of the sources of his notion from the Eastern and the Western traditions. What unites his view to nothing from the different periods is an existential praxis, and what I call an “anontology” that avoids reduction to either opposites of being and non-being (on-mēon).

It is axiomatic for most African scholars that the colonizers are responsible for the present problems facing the African continent. This is given much credence by Maduabuchi Dukor citing a barrage of issues which in summary pointed to the fact that the legacy of the colonizers to the African continent was ill willed to create chaos and therefore to make the African perpetually dependent on the colonizers. This paper accepts this fact but insists that the African as a human being (...) with free will and responsibility cannot continue to blame the colonizers when he has choice either to reject the colonial predetermined events or to accept them taking responsibility for his actions.

Essential Microeconomics is designed to help students deepen their understanding of the core theory of microeconomics. Unlike other texts, this book focuses on the most important ideas and does not attempt to be encyclopedic. Two-thirds of the textbook focuses on price theory. As well as taking a new look at standard equilibrium theory, there is extensive examination of equilibrium under uncertainty, the capital asset pricing model, and arbitrage pricing theory. Choice over time is given extensive coverage and includes a basic (...) introduction to control theory. The final third of the book, on game theory, provides a comprehensive introduction to models with asymmetric information. Topics such as auctions, signaling and mechanism design are made accessible to students who have a basic rather than a deep understanding of mathematics. Examples and diagrams are used to illustrate issues as well as formal derivations. (shrink)

A book Review of Artificial Knowing Gender and the Thinking Machine, by Alison Adam, Routledge: Taylor and Francis, 1998.

Nuestro interés en el contenido mental no-conceptual es, principalmente, la articulación de una versión sustantiva (no-trivial) de esta clase de contenido en la experiencia perceptual. El debate acerca del contenido no-conceptual ha girado, en su mayor parte, alrededor de su existencia; y los argumentos que se han ofrecido en su favor abogan por una versión no sustantiva según la cual el contenido no-conceptual es aquel que no satisface ciertos requisitos conceptuales. Así, para desarrollar una versión sustantiva del contenido mental no-conceptual (...) hemos apelado a la versión de la experiencia perceptual de propiedades espaciales ofrecida por Evans (1982 cap. 6). A partir de esto desarrollamos un nuevo argumento a favor del contenido no-conceptual de la experiencia perceptual que lo vincula a la actividad característica de la experiencia perceptual. Por último, exponemos uno de los ataques de McDowell (1996) a la noción de contenido no-conceptual y presentamos nuestras réplicas a este ataque, mostrando su insuficiencia. Al mostrar que la crítica de McDowell no es exitosa, consideramos que podríamos tener una versión del contenido no-conceptual de la experiencia que es inmune a esta línea de argumentación. (shrink)

In this article I contrast 17th and 18th explanations of hysteria including those of Sydenham and Willis with those given by Plato and pre-modern medicine. I show that beginning in the second decade of the 17th century the locus of the disorder was transferred to the nervous system and it was no longer connected with the womb as in Hippocrates and Galen; hysteria became identified with hypochondria, and was a disease contracted by men as well as women. I discuss the (...) purely mechanical explanation of hysteria given by Robert Boyle who attributed its cause to corporeal ideas as well as overly sensitive disposition of the nervous system. I relate this the mechanical theory of the nervous system prominent in Descartes' writings on physiology. The paper closes with a discussion of the contrast between early modern explanations of hysteria and the nature of man with those of Freud in the early 20th century. (shrink)

For beings like us, no ontological argument can possibly succeed. They are doomed to fail.

The three papers in this special section of Cognitive Processing continue and extend the December 2005 issue, which was devoted in its entirety to reviews, research reports, and laboratory reports on the theme of ‘Memory and the Extended Mind: embodiment, cognition, and culture’ (Sutton 2005). Like the papers in that issue, these are revised versions of papers first presented at two workshops on ‘Memory, Mind, and Media’ in Sydney on November 29–30 and December 2–3, 2004. Where that issue focussed specifically (...) on memory, these three papers deal with more general issues in the foundations of cognitive science. (shrink)

Even though the seventeenth-century French philosopher René Descartes has been remembered primarily for his contributions to Western philosophy, he also showed a curiosity about many aspects of the natural world. His mechanistic and rationalistic methods have been criticized as often as they have been praised, but they provided a framework for subsequent scientific inquiry.

Descartes, the textbooks say, divided human beings, or at least their minds, from the natural world. This is not just the consequence of metaphysical dualism, but of the concomitant indirect ‘ideas’ theory of perception. On the standard view, the soul must dimly infer the nature of the external world from the meagre, fragmentary, and often misleading input which is causally transmitted from objects through the nervous system to the brain and, ultimately, to the pineal gland. The metaphysical solipsism of the (...) cogito, on this picture, has its psychophysiological counterpart in the way Descartes sets all goings-on in nature at such a distance from the knowing subject who is temporarily and imperfectly united with a physical body. We cannot be sure, after all, that there are human beings rather than mere automata under the hats and cloaks we see from our window. (shrink)

Remembering seems, to philosophers and scientists, one of the most mystifying of human activities. Yet natural language users have no problem understanding what is meant by ‘memory’. Memory is simply the ability to recall personally experienced events and certain kinds of information such as facts, names, or faces; or how to perform certain actions, like riding a bike or playing chess. It is on this basis that people sometimes make claims about themselves or others having a good or bad memory, (...) especially for things like names, numbers, or faces. Why then is memory such a mystery? Because, firstly, of its diversity: memory enables us to perform a plethora of different tasks, including the continuous interpretation of every moment of consciousness. Secondly, different forms of memory have different standards of accuracy, and often dramatically different criteria for success. (shrink)

English instrument-maker, experimentalist, and natural philosopher who made key contributions in a wide range of areas including physiology, geology, and mechanics. Born on the Isle of Wight, Hooke showed early aptitude with the design of mechanical toys. At Westminster School he learnt mathematics and geometry, and at Christ Church, Oxford, he joined a remarkable group of natural philosophers working before the Restoration on physiological and physical topics (Frank 1980). Much of Hooke’s career was driven by financial uncertainty. As an employee, (...) working firstly with Robert Boyle and then as curator of experiments at the new Royal Society from 1662 to 1677, Hooke’s status as a professional in a society of gentlemen natural philosophers was problematic. He was continually concerned to establish his credibility, and his defences of ownership of his ideas were often vitriolic. (shrink)

Descartes thought about memory in the distinct contexts of method, metaphysics, medicine, mortality, and morals. Keenly aware of the fallibility and instability of natural corporeal memory, he considered various ways to bypass it or avoid relying on it, but also came to see its importance in understanding and dealing with the passions and the union of mind and body. His account of memory influenced Malebranche and associationist traditions, but was subject to sharp attack from critics who saw it as dangerously (...) materialist and chaotic. (shrink)

The word 'reason' as used today is used ambiguous in its meaning. It may denote either of two mental faculties: a lower reason associated with discursive, linear thinking, and a higher reason associated with direct apprehension of first principles of mathematics and logic, and possibly also of moral and religious truths. These two faculties may be provisionally named Reason (higher reason) and rationality (lower reason). Common language and personal experience supply evidence of these being distinct faculties. So does classical philosophical (...) literature, the locus classicus being Plato's Divided Line analogy. -/- The effect of currently using a single word to denote both faculties not only produces confusion, but has had the effect of decreasing personal and cultural awareness of the higher faculty, Reason. Loss of a sense of Reason has arguably contributed to various psychological, social, moral, and spiritual problems of the modern age. This issue was also a central concern of 19th century Transcendentalists, who reacted to the radical empiricism of Locke. It would be advantageous to adopt consistent terms that make explicit a distinction between higher and lower reason. One possibility is to re-introduce the Greek philosophical terms nous and dianoia for the higher and lower reason, respectively. This discussion has certain parallels with the recent theories of McGilchrist (2009) concerning the increasingly left-brain hemisphere orientation of human culture. (shrink)
