Open peer commentary on the article “Sensorimotor Direct Realism: How We Enact Our World” by Michael Beaton. Upshot: This commentary is broadly sympathetic to the claims made in the target article. I start by questioning whether we can have direct access to an external reality in such a way that our experience is not intrinsically private. I then suggest that the argument for direct realism presented here is inconclusive with regard to whether external objects play a causal or (...) a constitutive role. (shrink)

Alice Ambrose once criticized Moore for treating the proposition ‘There are external objects’ as an empirical one. She said that those who denied that we could know this proposition to be true would not accept any evidence as going against their denial of it, and were not regarding the issue of its truth as empirical. She also maintained that one could not point out an external object in the way in which one could point out a dime (...) or nickel and alleged on these grounds that saying that there are external objects is not the same sort of thing as saying that there are coins. The issue arose concerning Moore's paper, “Proof of an External World.“In “Reply to My Critics,” Moore pointed out that he had been concerned in “Proof of an External World” not to prove that we know that there are external objects, but rather to prove that there are external objects. But he applied Ambrose's remarks to that proposition. Moore rightly asserted that the fact that someone denies that there are external objects and treats all evidence as irrelevant to the issue does not show that the proposition he denies fails to be empirical.

Subjects perceived touch sensations as arising from a table (or a rubber hand) when both the table (or the rubber hand) and their own real hand were repeatedly tapped and stroked in synchrony with the real hand hidden from view. If the table or rubber hand was then ‘injured’, subjects displayed a strong skin conductance response (SCR) even though nothing was done to the real hand. Sensations could even be projected to anatomically impossible locations. The illusion was much less vivid, (...) as indicated by subjective reports and SCR, if the real hand was simultaneously visible during stroking, or if the real hand was hidden but touched asynchronously. The fact that the illusion could be significantly diminished when the real hand was simultaneously visible suggests that the illusion and associated SCRs were due to perceptual assimilation of the table (or rubber hand) into one’s body image rather than associative conditioning. These experiments demonstrate the malleability of body image and the brain’s remarkable capacity for detecting statistical correlations in the sensory input. (shrink)

The correspondence of a sensory object to the category of a descriptive statement requires a reflexive-identity of the object, and such a reflexive-identity is primarily based on the cognition of spatiality. Spatiality is, however, constituted through visual perception. There are only two occasions on which definitive reflexive-identity is exemplified: the infinitesimal point and the infinite “One,” and others are just human stipulations that meet pragmatic needs of rough identification of things at hand. However, if a spatial point is (...) not different from any so-called “other” spatial point, to validate the reflexive identity of any spatial point implies a validation of the reflexive identity of all spatial points. Thus, as “one” and “many” here become absolutely unitary, the infinitely small and the infinitely immense are identical. (shrink)

This article examines how the Kashmiri non-dualistic Śaiva philosophers Utpaladeva (tenth century) and Abhinavagupta (10th–11th centuries) present and criticize a theory expounded by certain Buddhist philosophers, identified by the two Śaiva authors as Sautrāntikas. According to this theory, no entity external to consciousness can ever be perceived since perceived objects are nothing but internal aspects (ākāra) of consciousness. Nonetheless we must infer the existence of external entities so as to account for the fact that consciousness is aware of (...) a variety of objects: just as a mirror takes on a variegated appearance only by reflecting a multiplicity of objects that remain external to it, in the same way, phenomenal variety can be explained only by assuming the existence of various objects external to consciousness. In Īśvarapratyabhijñākārikās I, 5, 8–9 and their commentaries, Utpaladeva and Abhinavagupta endeavour to criticize this theory, which challenges their own idealistic principles: according to them, the Sautrāntikas’ inference is neither legitimate nor even possible. The passage is particularly telling as regards the strategy developed by Pratyabhijñā philosophers with respect to their Buddhist opponents: they make use of certain arguments propounded by Dharmakīrti in defense of Vijñānavāda in order to criticize the Sautrāntikas’ inference, but they also exploit this discussion to underline the superiority of their idealism over that of the Vijñānavādins.

In accord with the theme of the present volume on , it is not so much the aim of this essay to provide a detailed account of particular lines of argument, as it is to suggest something of the manner in which so-called 'Buddhist idealism' unfolded as a tradition not just for Buddhists, but within Indian philosophy more generally. Seen from this perspective, Buddhist idealism remained a current within Indian philosophy long after the demise of Buddhism in India, in about (...) the twelfth century, and endured in some respects at least until the Mughal age, when the last thinker to be examined here, the Jain teacher Yaśovijaya, was active.

Descartes entitled the Sixth Meditation "The existence of material things, and the real distinction between mind and body." But these topics take up only two paragraphs, about one-third of the way into the Sixth Meditation (which is the longest of the six). The other topics in the Meditation partly pertain to the cognitive faculties that a seeker after knowledge must employ: senses, imagination, and intellect. They also concern the mind–body relation: not only is it to be shown that mind and (...) body are distinct, but also that they are “closely joined” together. The joining of mind to body contributes to explanations of the cognitive faculties, for such a joining is, in Descartes’ view, necessary for the operation of sense and imagination, whereas the exercise of the intellect in the pursuit of metaphysical results -- as in his argument for mind–body distinctness -- takes place without the mind interacting with the body. But this still doesn't account for the most sustained discussion in the Sixth Meditation, which concerns the role of the senses in informing us about the world around us. While the trustworthiness of the senses has been under suspicion up to this point in the Meditations, now the senses are rehabilitated. They can serve to acquaint us with the world of bodies, for the purposes of empirical investigation serving natural philosophy but, more usually, for the practical purpose of informing us of potential benefits and harms in our immediate environment. In this regard, Descartes considers the ways in the senses might be subject to local errors or might, if used inappropriately, draw us into systematic error. But the previous results of the Meditations now offer the means for avoiding such systematic error, and the reflections of the Sixth Meditation can guide us toward practical uses of the senses in ways that reduce error. In the end, the senses are found to be trustworthy for the guidance of action, and this trustworthiness extends even to a qualitative experience such as color, which helps us to discriminate among the bodies that we see.

Harold Langsam has recently presented a novel observational account of self-knowledge. I critically discuss this account and argue that it fails to provide a uniform understanding of how we are able to know the contents of our own thoughts.

The physical interpretation of induced representation intertwining as a process of materialization or localization is extrapolated to mappings (which are not intertwinings) between configuration and momentum representations. Propagation of extended particles composed of an external and an internal mode is a combination of two generalized materializations and two generalized localizations. Our aim is to submit, in the spinless case, the idea that mappings from external representations to internal ones are possible alternatives, probability amplitudes of which must be summed (...) up in the whole propagator. However, it turns out that they lead to different final states and then correspond to 64 different propagators and not to alternatives of the same propagation. In addition to being transitions from one location to another, these propagations contain processes of interconversion between internal and external modes which are responsible for creation and annihilation of the extended particle. The physical interpretations are striking, while the mathematical stricture is poor. Inconsistencies of the model are outlined. (shrink)

This article is an investigation into Hegel's claim that teleology is the truth of mechanism, which Hegel puts forward in the objectivity section in the Science of Logic. Contrary to most accounts of this section of the Logic, I make a case for a reading of Hegel's conception of external purposiveness according to which the latter makes a positive contribution to the structural development of the concepts of the Logic. I argue that external purposiveness plays a major role (...) in understanding the Hegelian claim of teleology as the truth of mechanism. More specifically, I argue that structures of external purposiveness provide the conditions for the individuation of mechanical objects. (shrink)

The experimental revolution in the social sciences is one of the most significant methodological shifts undergone by the field since the ‘quantitative revolution’ in the nineteenth century. One of the often valued features of social science experimentation is precisely the fact that there are clear methodological rules regarding hypothesis testing that come from the methods of the natural sciences and from the methodology of RCTs in the biomedical sciences, and that allow for the adjudication among contentious causal claims. We examine (...) critically this claim and argue that some current understandings of the practices that surround social science experimentation overestimate the degree to which experiments can actually fulfil this role as “objective” adjudicators, by neglecting the importance of shared background knowledge or assumptions and of consensus regarding the validity of the constructs involved in an experiment. We take issue with the way the distinction between internal and external validity is often used to comment on the inferential import of experiments, used both among practitioners and among philosophers of science. We describe the ways in which the more common use of the internal/external distinction differs from Cook and Campbell’s original methodological project, in which construct validity and the four-fold validity typology were all important in assessing the inferential import of experiments. We argue that the current uses of the labels internal and external, as applied to experimental validity, help to encroach a simplistic view on the inferential import of experiments that, in turn, misrepresents their capacity to provide objective knowledge about the causal relations between variables.

Questions concerning perception are as old as the field of philosophy itself. Using the first-person perspective as a starting point and philosophical documents, the study examines the relationship between knowledge and perception. The problem is that of how one knows what one immediately perceives. The everyday belief that an object of perception is known to be a material object on grounds of perception is demonstrated as unreliable. It is possible that directly perceived sensible particulars are mind-internal images, shapes, (...) sounds, touches, tastes and smells. According to the appearance/reality distinction, the world of perception is the apparent realm, not the real external world. However, the distinction does not necessarily refute the existence of the external world. We have a causal connection with the external world via mind-internal particulars, and therefore we have indirect knowledge about the external world through perceptual experience. The research especially concerns the reasons for George Berkeley’s claim that material things are mind-dependent ideas that really are perceived. The necessity of a perceiver’s own qualities for perceptual experience, such as mind, consciousness, and the brain, supports the causal theory of perception. Finally, it is asked why mind-internal entities are present when perceiving an object. Perception would not directly discern material objects without the presupposition of extra entities located between a perceiver and the external world. Nevertheless, the results show that perception is not sufficient to know what a perceptual object is, and that the existence of appearances is necessary to know that the external world is being perceived. However, the impossibility of matter does not follow from Berkeley’s theory. The main result of the research is that singular knowledge claims about the external world never refer directly and immediately to the objects of the external world. A perceiver’s own qualities affect how perceptual objects appear in a perceptual situation. (shrink)

This is a book that takes seriously both skepticism and the philosophical theories in tension with it. It argues with great force that there are plausible versions of skepticism that cannot, without question-begging, be refuted, yet it rejects the inference from that conclusion to the permissibility of an anything-goes attitude in philosophy. Instead, the book represents a distinctive kind of agnosticism: rejecting naive realism and adopting agnosticism even toward sophisticated realism forces us to adopt a kind of relativism, but leaves (...) open the possibility of ground rules for philosophical dialectic and challenges us to provide them. Philosophy After Objectivity sets forth a detailed metaphilosophy intended to meet that challenge. The book is too rich and subtle to discuss as a whole here, but its account of the internal-external reasons controversy is central to its metaphilosophy and has an admirable sharpness that makes it a good focus for a critical study. This controversy, as set out in Chapter 4, “Reasons, Truth, and Relativism,” will be my concern. (shrink)

External freedom is the central good protected in Kant's legal and political philosophy. But external freedom is perplexing, being at once freedom of spatio‐temporal movement and a form of noumenal or ‘intelligible’freedom. Moreover, it turns out that identifying impairments to external freedom nearly always involves recourse to an elaborated system of positive law, which seems to compromise external freedom's status as a prior, organizing good. Drawing heavily on Kant's understanding of the role of empirical ‘anthropological’information in (...) constructing a Doctrine of Right, or Rechtslehre, this essay offers an interpretation of external freedom that makes sense of its simultaneous spatio‐temporality, dependence on positive law, intelligibility (or ‘noumenality’), and a priority. The essay suggests that this account of Kantian external freedom has implications both for politics and for the metaphysics of everyday objects and institutions. (shrink)

Cinematic motion is, I argue, a genuine and intrinsic property of some cinematic works and not just a matter of how things look to us. It is an event—an item's change of position—happening prior and external to our sensory responses to movies. I therefore defend against common-sense illusionism a minority opinion within cinema studies: that movie viewing normally occasions veridical perceptions of a kind of objective displacement. I also dispute another version of anti-illusionist realism about cinematic motion, the implication (...) that cinematic motion, like colour, is a response-dependent property. The impression of motion, I contend, is not produced by the visual system's operations. It is a sensory representation of a physical property of a particular type of external object. (shrink)

Externalities are an important concept in economic theories of market failure, aiming to justify state regulation of the economy. This article explores the concept of externalities from a philosophical perspective. It criticizes the utilitarian nature of economic analyses of externalities, showing how they cannot take into account values like freedom and justice. It then develops the analogy between the concept of externalities and the 'harm principle' in political philosophy. It argues that the harm principle points to the need for a (...) theory of basic interests to judge when a harm is imposed. Similarly, externality analyses should use such a theory of basic interests as the basis for judgments about legitimate state intervention. This proposal is defended against objections, and illustrated with a case study of the US Supreme Court's ruling on the Affordable Care Act, which shows how the judicial reasoning implicitly interprets externalities in terms of basic interests.

SummaryStarting with Descartes, epistemology has been almost entirely based on first person knowledge. We must begin, according to the usual story, with what is most certain: knowledge of our own sensations and thoughts. In one way or another we then progress, if we can, to knowledge of an objective external world. There is then the final, tenuous, step to knowledge of other minds.In this paper I argue for a total revision of this picture. All propositional thought, whether positive or (...) skeptical, whether of the inner or of the outer, requires possession of the concept of objective truth, and this concept is accessible only to those creatures in communication with others. Third person knowledge – knowledge of other minds – is thus conceptually basic. But such knowledge is impossible without knowledge of a shared world of objects in a shared time and space. Thus the acquisition of knowledge is not based on a progression from the subjective to the objective; it emerges holistically, and is interpersonal from the start. (shrink)

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion (...) is our natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

Joint attention to an external object at the end of the first year is typically believed to herald the infant's discovery of other people's attention. I will argue that mutual attention in the first months of life already involves an awareness of the directednesss of attention. The self is experienced as the first object of this directedness followed by gradually more distal 'objects'. this view explains early infant affective self-consciousness within mutual attention as emotionally meaningful, rather than (...) as bearing only a spurious similarity to that in the second and third years of life. Such engagements precede and must inform, rather than derive from, conceptual representations of self and other, and can be better described as self-other conscious affects. (shrink)

Why do people create extra representations to help them make sense of situations, diagrams, illustrations, instructions and problems? The obvious explanation— external representations save internal memory and com- putation—is only part of the story. I discuss seven ways external representations enhance cognitive power: they change the cost structure of the inferential landscape; they provide a structure that can serve as a shareable object of thought; they create persistent referents; they facilitate re- representation; they are often a more (...) natural representation of structure than mental representations; they facilitate the computation of more explicit encoding of information; they enable the construction of arbitrarily complex structure; and they lower the cost of controlling thought—they help coordinate thought. Jointly, these functions allow people to think more powerfully with external representations than without. They allow us to think the previously unthinkable. (shrink)

We test competing theoretical perspectives of family firm governance in two separate studies by investigating whether family firm control moderates the detrimental effect of a management training ground on internal auditor objectivity and on the external auditor’s decision to rely on the internal audit function. In Study 1, we assess the objectivity of internal auditors working under an IAF that serves as a MTG or non-MTG and located in a family or non-family firm. A key result of Study 1 (...) is the mitigating role of family firm control, as we find that the objectivity of internal auditors is reduced when the IAF serves as a MTG but only in non-family firms. When the IAF is located in a family-controlled firm, the objectivity of internal auditors is unaffected by the opportunity to be promoted into management positions outside of the IAF. In Study 2, we utilize a controlled laboratory experiment with experienced Big 4 auditors as participants and examine their decision to rely on an IAF when it serves as a MTG. Our analyses indicate that external auditors reduce their reliance on non-family firm IAFs that are also MTGs and their decision is fully mediated by the perceived objectivity of non-family firm internal auditors. In contrast, external auditors’ reliance on family firm IAFs and their perceptions of internal auditor objectivity are unaffected under a MTG regime. The results of Studies 1 and 2 provide support for the alignment perspective of family firms. (shrink)

This chapter examines the role of law in European Union (EU) external relations from two perspectives. First, it examines the EU as a rule‐based (international) actor Law and focuses mainly on EU law‐ governs both the extent of the European Union's external powers and their exercise, the constitutional foundations of EU external relations and the legal principles that govern external action. Second the chapter turns to the European Union's characteristic use of law as an instrument and (...) objective of its foreign policy, the European Union as a promoter of a rule‐based international order. The role of the Parliament in the conclusion of international treaties, which are often regulatory or quasi‐legislative in character, brings to the final theme of this contribution: the role played by law as both an instrument and a goal of EU foreign policy.

Speculations of this last type have existed from a much earlier period in the Eastern civilizations, particularly in those areas affected by Hindu philosophy. For example, in the Sánkhya or Yoga-Sútras by Patánjali, we find a very radical distinction between the external world and the individual soul or self. But for Sánkhya, the "external world" includes everything that could possibly be an object of consciousness--physical objects and their relationships, sensations and imaginations, dreams, memories, expectations, etc. In other (...) words, for Sánkhya, our thoughts or desires, far from being the "cause" of the external world as in some forms of Western idealism, are simply other aspects of the external world itself, that is, merely particular items in the totality of our consciousness. On the other hand, the individual soul or self is only the spectator of this consciousness and not ordinarily conscious of itself. If the self were to become conscious of "itself" in the same way that it was conscious of all other objects, all that it would really be aware of would be another object of consciousness---the mere idea of itself, while it would remain the unknown knower. Nevertheless, realizing that a completely "unconscious self" would be simply a postulate of thought and therefore part of the external world, the Sánkhya-Sútras emphasize that the self can become aware of itself by another and more intuitive means.

In lieu of an abstract, here is a brief excerpt of the content:150 PERCEPTIONS, OBJECTS AND THE NATURE OF MIND In this paper I consider the relation between perceptions and objects for Hume and the bearing which this has on his conception of the mind as composed of perceptions. But first it is necessary to distinguish at least two senses in which he uses the term 'object'. In the first, "perceptions of the human mind" — both impressions and ideas (...) — are referred to as "our objects" (T 1,2). Objects in this sense are intentional objects. Hume almost consistently uses the noun 'perception', rarely the verb 'to perceive'. This serves to emphasize that for him perception is an object, not the perceiving of an object — a departure from the tradition of Locke and Berkeley for whom perceptions are cognitive acts having objects. That perception is not conceived by Hume as a cognitive act or form of awareness but purely as an object of awareness is evident when he says, For since all actions and sensations of the mind are known to us by consciousness, they must necessarily appear in every particular what they are, and be what they appear. Everything that enters the mind, being in reality a perception, 'tis impossible anything shou'd to feeling appear different. This were to suppose, that even when we are most intimately conscious, we might be mistaken (T 190). 1 Or again, "The only existences, of which we are certain, are perceptions, which being immediately present to us by consciousness, command our strongest assent...." (T 212). In its other sense the term 'object' is used to denote bodies, or that to which we attribute a continued existence "distinct from the mind and perception", or, borrowing Locke's expression "external 151 objects". It is just because we attribute a continued and independent existence to bodies that we distinguish them from perceptions, for "all impressions are internal and perishing existences, and appear as such" (T 194). But while we make this distinction in our everyday role of common man, the difference between a perception and an (external) object is really only a difference between two types of perceptions, on the one hand those that are characterized in their occurrence by constancy and coherence, and on the other those, for example the passions, which exhibit a different type of "regularity" in their occurrence (T 195). The constancy and coherence which some perceptions exhibit, together with a natural tendency of the mind "to bestow on the objects a greater regularity than what is observ'd in our mere perceptions" (T 197) causes us to attribute to these perceptions an uninterrupted and independent existence, an existence which is, of course, fictitious, because all perceptions are really internal and perishing. 'Tis certain, that almost all mankind, and even philosophers themselves, for the greatest part of their lives, take their perceptions to be their only objects, and suppose, that the very being, which is intimately present to the mind, is the real body or material existence (T 206). This is not to say, however, that "what any common man means by a hat, or shoe, or stone" (T 202) he also believes to be a perception. What he does believe is that the hat or the shoe is immediately present to the mind, or directly appears to his consciousness. It is Hume, the philosopher, who is here interposing the philosophical doctrine that "no beings are ever present to the mind but perceptions" (T 212). This is, of course, not an empirical generalization. It is the definition of a perception as "whatever can be present 152 to the mind" (Abstract 647). It is this definition which gives sense to the statement "their perceptions are their only objects", the term "objects" here referring to "external objects". And the common man would, no doubt, be surprised to learn that these hats, shoes, etc., which directly appear to his consciousness, are by that circumstance really only his own perceptions which he has imagined, falsely, to have a continued and independent existence. Only a few experiments, however, are needed for the philosopher to realize that perceptions, i.e., what is present to the mind, do not have a continued and independent existence. Unable to give up his vulgar... (shrink)

We study the one-seller/two-buyer bargaining problem with negative identity-dependent externalities with an alternating offer bargaining model in which new owners of the object have the opportunity of resale. We identify the generically unique subgame perfect equilibrium outcome. The resale opportunity increases the competition among the buyers and therefore benefits the seller. When competition between buyers is very fierce, the seller may prefer to respond to bids rather than to propose an offer herself: a first-mover disadvantage.

Hume’s understanding of the external world, particularly, his conception of objects, or what he occasionally refers to as “bodies,” is the subject of much dispute. Are objects mind-independent? Or, are they just what we see, feel, smell, taste, or touch? In other words, are objects just sense data? Or, are they ideas about sense data? Or, are objects, somehow, mind-independent, but we have ideas of them, and we receive sense data from them? In this paper, I provide some answers (...) to these questions—by way of distinguishing between the vulgar position, the philosophical position, and Hume’s position. (shrink)

This paper provides a brief history of some critical responses and expansions of Hume on external objects, with a particular emphasis on the relevance of developmental psychology.

Discussions of reproducibility are casting doubts on the credibility of experimental outcomes in the life sciences. Although experimental evolution is not typically included in these discussions, this field is also subject to low reproducibility, partly because of the inherent contingencies affecting the evolutionary process. A received view in experimental studies more generally is that standardization (i.e., rigorous homogenization of experimental conditions) is a solution to some issues of significance and internal validity. However, this solution hides several difficulties, including a reduction (...) of external validity and reproducibility. After explaining the meaning of these two notions in the context of experimental evolution, we import from the fields of animal research and ecology and suggests that systematic heterogenization of experimental factors could prove a promising alternative. We also incorporate into our analysis some philosophical reflections on the nature and diversity of research objectives in experimental evolution. (shrink)

Why do people create extra representations to help them make sense of situations, diagrams, illustrations, instructions and problems? The obvious explanation – external representations save internal memory and computation – is only part of the story.

In this paper I argue that there are in fact external relations in Russell’s sense. The level at which we are forced to acknowledge them is, however, not the level of relations between concrete individual objects. All relations of this kind, which I will call “inter-individual” relations, can be construed as supervenient on the monadic properties of their terms. But if we pursue our ontological analysis a little bit deeper and consider the internal structure of a concrete individual, then (...) we will inevitably find irreducible external relations. I mean for example the relation of instantiation (in the frame of a realist’s theory) or that of concurrence (in the frame of a trope theory). I will show that such “intra-individual” relations – the relations that make up the internal structure of a concrete individual out of more primitive metaphysical “building blocks” like universals or tropes – could not (even in principle) be construed as supervenient.
