Is the sense‐data theory, otherwise known as indirect realism, a form of representationalism? This question has been under‐explored in the extant literature, and to the extent that there is discussion, contemporary authors disagree. There are many different variants of representationalism, and differences between these variants that some people have taken to be inconsequential turn out to be key factors in whether the sense‐data theory is a form of representationalism. Chief among these are whether a representationalist takes (...) the phenomenal character of an experience to be explicable in virtue of the properties of an experience that represent something or explicable in virtue of that which gets represented. Another is whether representationalists hold a non‐reductionist, or naturalistically or non‐naturalistically reductionist variant of representationalism. In addition, subtle differences in what one takes phenomenal character to be on the sense‐data theory – either awareness of sense‐data or the sense‐data themselves – together with one's account of representation, are crucial factors in determining whether sense‐data theory is compatible with representationalism. This paper explores these relationships and makes manifest the complexities of the metaphysics of two central theories of perception. 1 Many thanks are due to Clare Batty, Derek Brown, and James Stazicker for discussion and feedback on earlier drafts, which made this essay better than it would otherwise have been.

It is important for our purposes to notice that in this first reduction of Theætetus' definition of knowledge as perception, Plato has introduced the distinction between sense object and physical object, for he has specifically said, "when the same wind is blowing, one of us feels chilly, the other does not." In using this example. Plato has, as Cornford observes, raised the question of how the several sense objects are related to the single physical object. This question is one of (...) the two major questions with which this paper will deal, since it is, as I have remarked, the more important question concerning the ontological status of sense-data. Cornford feels that Protagoras probably held that the physical object is both hot and cold, different observers perceiving different aspects of the same object. That is, Cornford suggests that Protagoras' own answer to this question of the relation between sense-data and physical objects is one of complete identification in every case. We will see that this theory is similar in many ways to the one worked out by Plato in the Theætetus, but the distinction between the physical object and the sense object, between the wind which feels hot and cold to different people, makes certain characteristic differences between Plato's and Protagoras' theory. Before going on to examine these differences, it is necessary to follow the further development of Plato's general theory of perception. (shrink)

In this paper, I present a version of a sense-data approach to perception, which differs to a certain extent from well-known versions like the one put forward by Jackson. I compare the sense-data view to the currently most popular alternative theories of perception, the so-called Theory of Appearing (a very specific form of disjunctivist approaches) on the one hand and reductive representationalist approaches on the other. I defend the sense-data approach on the basis that it improves substantially on those (...) alternative theories. (shrink)

We face reality presented with the data of conscious experience and nothing else. The project of early modern philosophy was to build a complete theory of the world from this starting point, with no cheating. Crucial to this starting point is the data of conscious sensory experience – sense data. Attempts to avoid this project often argue that the very idea of sense data is confused. But the sense-data way of talking, the sense-data language, can be freed from every (...) blemish using ideas from contemporary metaontology. We can adopt a sense-data framework that vindicates the traditional claims of sense-data theories and leads to plausible theories of perception and color. We can, we should, and in a sense, we must. Yet when we do, we face the traditional problem of external world skepticism, head-on. The real challenge of skepticism is forced upon us; it cannot honestly be avoided using externalist tricks, burden of proof shifting, or other razzle dazzle. But the challenge can be met: we are rational to posit the external world as the best explanation of the many synchronic and diachronic patterns over our sense-data. This paper argues for all of these points and ends with a plea for analytic empiricism – a traditional sense-data version of empiricism that uses all of the tools of analytic philosophy while avoiding the more questionable doctrines of the Vienna Circle (phenomenalism, verificationism). Analytic empiricism is our last best hope for completing the great philosophical project of early modern philosophy. (shrink)

The theory of knowledge in early twentieth-century Anglo American philosophy was oriented toward phenomenally described cognition. There was a healthy respect for the mind-body problem, which meant that phenomena in both the mental and physical domains were taken seriously. Bertrand Russell's developing position on sense-data and momentary particulars drew upon, and ultimately became like, the neutral monism of Ernst Mach and William James. Due to a more recent behaviorist and physicalist inspired "fear of the mental", this development has been (...) down-played in historical work on early analytic philosophy. Such neglect assumes that the "linguistic turn" is a proper and permanent effect of twentieth-century philosophy, an assumption that distorts early analytic historiography, and begs a substantive philosophical question about thought and cognition.

Sense data are the alleged mind-dependent objects that we are directly aware of in perception, and that have exactly the properties they appear to have. For instance, sense data theorists say that, upon viewing a tomato in normal conditions, one forms an image of the tomato in one's mind. This image is red and round. The mental image is an example of a “sense datum.” Many philosophers have rejected the notion of sense data, either because they believe that perception gives (...) us direct awareness of physical phenomena, rather than mere mental images, or because they believe that the mental phenomena involved in perception do not have the properties that appear to us (for instance, I might have a visual experience representing a red, round tomato, but my experience is not itself red or round). Defenders of sense data have argued, among other things, that sense data are required to explain such phenomena as perspectival variation, illusion, and hallucination. Critics of sense data have objected to the theory's commitment to mind-body dualism, the problems it raises for our knowledge of the external world, its difficulty in locating sense data in physical space, and its apparent commitment to the existence of objects with indeterminate properties.

This commentary on Adam Pautz's excellent book, Perception, explores the consequences of “spatial illusionism,” the view that the spatial properties presented in experience aren't instantiated in the extra-mental world. First, I consider whether spatial illusionism entails that our ordinary beliefs about the physical world are mostly false. I then argue that spatial illusionism threatens to undermine two arguments Pautz's defends in Perception: his argument that sense data theory is incompatible with physicalism, and his central argument against the internal physical (...) state view of perception.

This paper examines and defends the view that the immediate objects of visual perception, or what are often called sense data, are parts of the facing surfaces of physical objects-the naturalized sense data (NSD) theory. Occasionally defended in the literature on the philosophy of perception, most famously by G. E. Moore (1918-1919), it has not proved popular and indeed was abandoned by Moore himself. The contemporary situation in the philosophy of perception seems ripe for a revaluation of the NSD (...) theory. however. The NSD theory allows us to accommodate the very real shortcomings in uncritical direct realism without postulating the existence of non-physical sense data in a way that has seemed to many incompatible with any robust form of philosophical naturalism.The argument to establish the NSD theory proceeds in two stages. In §II I argue against the direct realist that we perceive three-dimensional material objects in virtue of perceiving parts of their surfaces. The argument for this conclusion involves clearly distinguishing (in § I) between two notions that have tended to be run together in discussions of perception---namely, immediate perception and direct perception. In §III I argue against the sense-datum theorist that those parts of the surfaces of those objects are not themselves perceived in virtue of the perception of anything else. (shrink)

Although it has been something of a fetish for philosophers to distinguish between hallucination and illusion, the enduring problems for philosophy of perception that both phenomena present are not essentially different. Hallucination, in its pure philosophical form, is just another example of the philosopher’s penchant for considering extreme and extremely idealized cases in order to understand the ordinary. The problem that has driven much philosophical thinking about perception is the problem of how to reconcile our evident direct perceptual contact with (...) objects and properties with the equally evident fact that there is no phenomenological signal separating error and truth. “The obscure object of hallucination” offers a subtle and plausible solution to this problem and one that solves the problem generally, not just in the special case of hallucination. Johnston’s objective is to offer a theory of perception that meets two constraints: (1) that it provide an explanation of the possibility of delusive and veridical sensings that are indistinguishable from the first-person perspective and (2) that it count as form of direct realism where this is taken to involve acquaintance with the objects of perception. Johnston uses the first constraint to rule out disjunctivism. The second constraint is used to rule out conjunctivism, which as Johnston uses the term, includes most of the widely adopted philosophical theories of perception. Johnston also develops his own sophisticated and interesting theory of perception. In what follows, I will discuss the relation of Johnston’s theory to conjunctivism, examine one of his anti-conjunctivist arguments and finally compare Johnston’s theory with some other versions of direct realism. These topics constitute a very incomplete selection of the important issues discussed in this rich and interesting paper. I will also not disagree, in any fundamental way, with any of the central theses of Johnston’s discussion.. (shrink)

Experiences of all kinds have a distinctive character, which marks them out as intrinsically different from states of consciousness such as thinking. A plausible view is that the difference should be accounted for by the fact that, in having an experience, the subject is somehow immediately aware of a range of phenomenal qualities. For example, in seeing, grasping and tasting an apple, the subject may be aware of a red and green spherical shape, a certain feeling of smoothness to touch, (...) and a sweet sensation. Such phenomenal qualities are also immediately present in hallucinations. According to the sense-data theory, phenomenal qualities belong to items called “sense-data.” In having a perceptual experience the subject is directly aware of, or acquainted with, a sense-datum, even if the experience is illusory or hallucinatory. The sense-datum is an object immediately present in experience. It has the qualities it appears to have. (shrink)

Examples of sensory illusion show the failure of the attempt of traditional sense-datum theory to account for something's phenomenally appearing to be F by postulating the existence of a sense-datum that is actually F. the Muller-Lyer Illusion cannot be explained by postulating two sensibly presented lines that actually have the lengths the physical lines appear to have. Illusions due to color contrast cannot be explained by postulating sense-data that actually have the colors the physical samples appear to have.

In the present state of philosophy in the English-speaking world, to choose to talk about sense data may seem perverse. What could be more boring for one's audience than to attempt variations on so threadbare a theme? And worse, what could be more unfashionable in the aftermath of Wittgenstein and Austin? My reasons for selecting this unpromising topic are twofold. First, the general theme of this series of lectures is empiricism. And whatever meanings we put upon that ambiguous word, it (...) is clear that as a matter of history the problems of perception have been important problems for nearly all those philosophers who would consider themselves to be empiricists. And however unsatisfactory sense datum theories of perception may now be held to be, such theories have been central to the empiricist tradition. Secondly, it is important not to be too much impressed by the fact that a particular philosophical opinion is fashionable or unfashionable. The former certainly does not guarantee its truth nor the latter its falsity. It has often been remarked that philosophical opinions are very rarely refuted. Instead they fall out of vogue only to return some years later in another guise. It is perhaps time to take another look at the notion of sense data. The most ingenious and persistent attacks on analyses of perception in terms of sense data have been at best indecisive, as Professor Ayer showed in his reply to Austin's Sense and Sensibilia.

Two concepts of utmost importance for the analytic philosophy of the twentieth century, “sense-data” and “knowledge by acquaintance”, were introduced by Bertrand Russell under the influence of two idealist philosophers: F. H. Bradley and Alexius Meinong. This paper traces the exact history of their introduction. We shall see that between 1896 and 1898, Russell had a fully-elaborated theory of “sense-data”, which he abandoned after his analytic turn of the summer of 1898. Furthermore, following a subsequent turn of August 1900—-after (...) he became acquainted with the works of Peano and later of Frege—-Russell gradually developed another theory of sense-data. With the collaboration of G. E. Moore, Russell reintroduced the term “sense-data” in 1911. Concomitantly with this move, Russell introduced the epistemological term “knowledge by acquaintance”, which came to designate the grasping of sense-data and universals. (shrink)

L’article vise à établir un lien entre les travaux de Russell sur les fondements de la géométrie et ses célèbres textes des années 1911-1914 sur la perception, la matière et les sense-data. Nous insistons d’abord sur le fait que la notion russellienne de donnée sensorielle n’est pas phénoménaliste : les sense-data des Problèmes de Philosophie sont des objets extérieurs aussi peu mentaux que les corps matériels. L’accent est ensuite mis sur l’article On Matter : Russell y introduit pour la première (...) fois l’idée que les sense-data n’ont pas une, mais deux positions — une position où ils sont vus et une position d’où ils sont vus. Cette manœuvre permet à Russell de considérer la donnée sensorielle comme le point d’intersection neutre de deux ensembles fondamentalement différents : une série « physique », matérielle, et une série de « perspectives », mentales. L’idée qu’une même chose peut être classée sous différentes catégories, donc que le mode de classification aristotélicien en espèce et en genre n’est pas le seul concevable, est à la fois la clé de voûte de la théorie des relations entre « sense-data » et « physical things » de 1914 et le nerf du ralliement ultérieur au « monisme neutre ». Nous défendons, dans une troisième partie, que ce canevas n’est lui-même qu’un lointain écho de la conception de la géométrie projective définie comme théorie générale des relations d’incidence développée par Russell dans The Principles of Mathematics (1903).

Book description: * G. E. Moore is a key figure in analytic philosophy * Sixteen specially written essays reflect the current resurgence of interest in Moore 's work * Superb international line-up of contributors * A valuable resource for anyone working in epistemology or ethics These sixteen original essays, whose authors include some of the world's leading philosophers, examine themes from the work of the Cambridge philosopher G. E. Moore, and demonstrate his considerable continuing influence on philosophical debate. Part I (...) bears on epistemological topics, such as scepticism about the external world, the significance of common sense, and theories of perception. Part II is devoted to themes in ethics, such as Moore 's open question argument, his non-naturalism, utilitarianism, and his notion of organic unities. (shrink)

The claim that perceptual illusions can motivate the existence of sense-data is both familiar and controversial. My aim is to carve out a subclass of illusions that are up to the task, and a subclass that are not. It follows that when we engage the former we are not simply incorrectly perceiving the world outside ourselves, we are directly perceiving a subjective entity: one’s grip on the external world has been marginalized – not fully lost, but once-removed. However, admitting that (...) various illusions do not give evi¬dence for sense-data considerably limits the power of the argument from illusion (Section 6) and brings out its distinctness from the argument from perceptual relativity (Section 7). To reach these conclusions we will examine the role of ambiguity in perception (Section 3), its connection to illusion (Section 4), and the link reference has to every element of this dis¬course (Sections 2 and 5).

We perceive the objective world through a subjective perceptual veil. Various perceived properties, particularly “secondary qualities” like colours and tastes, are mind-dependent. Although mind-dependent, our knowledge of many facts about the perceptual veil is immediate and secure. These are well-known facets of sense-datum theory. My aim is to carve out a conception of sense-datum theory that does not require the immediate and secure knowledge of a wealth of facts about experienced sense-data (§1). Such a theory is of (...) value on its own, given well-known challenges to epistemic foundationalism. Beyond this such a theory helps demonstrate how sense-datum theory can accommodate challenging perceptual phenomena like shape and size constancies (§3). These ideas are bridged by the roots of perceptual ambiguity (§2). In brief, tapering acquaintance knowledge creates space for perceptual representation to resolve the ambiguities in presented objects seemingly inherent in scenarios involving perceptual constancies. Thus, I offer a two-factor (acquaintance-representation) sense-datum theory to meet the challenge posed by constancies. Following Smith (2002), from whom this challenge is drawn, my focus is on shape and size constancies. Other constancies, notably colour constancy, are treated elsewhere (Brown 2014). (shrink)

In this article, I will discuss Aron Gurwitsch's criticism of Edmund Husserl's theory of hyletic data. First, Husserl’s doctrine will be summarized in its earliest complete formulation. It will then be seen that Gurwitsch's problem with this doctrine is primarily due to his acceptance of gestalt theoretic organization. He conceives of hyletic data as being a kind of formless stuff that undergoes organiza-tion by morphetic components of the noesis, which represents a dualism in percep-tion. Instead, Gurwitsch wants to show (...) us that the organization of these contents is autochthonous. I will consider Gurwitsch's criticism against Husserl's own writings, and especially those that were not available to Gurwitsch. It will be seen that Husserl continues to develop this doctrine and that it very interestingly undergoes a kind of noematization and exhibits certain displays of autochthonous organization that in the end are not far from Gurwitsch's own conception of these affairs.Este artículo versará sobre la crítica de Aron Gurwitsch de los data hylé-ticos de Edmund Husserl. En primer lugar, se resumirá la doctrina de Husserl en su primera formulación completa. A continuación, se verá que el problema de Gur-witsch con esta doctrina se debe principalmente a su aceptación de la organización teórica de la Gestalt. Él concibe los data hyléticos como una especie de material amorfo que se somete a organización por los componentes de morphé de la noesis, lo que representa un dualismo en la percepción. En cambio, Gurwitsch quiere mos-trarnos que la organización de estos contenidos es autóctona. Se examinará la críti-ca de Gurwitsch acerca de los escritos del propio Husserl y especialmente de aque-llos que no estuvieron al alcance de Gurwitsch. Se verá que Husserl sigue desarro-llando esta doctrina y que curiosamente sufre una especie de noematización y muestra ciertas manifestaciones de organización autóctona que, a la postre, no están lejos de la concepción gurwitscheana de estos asuntos.

Howard Robinson’s “revised causal argument” for the sense-datum theory of perception combines elements from two other arguments, the “original” causal argument and the argument from hallucination. Mark Johnston, however, has argued that, once the nature of the object of hallucinatory experience is properly addressed, the errors in hallucination-based arguments for conjunctivist views of perception like the sense-datum theory become apparent. I outline Robinson’s views and then consider the implications of Johnston’s challenge for the revised causal argument.

When philosophers of perception contemplate concrete examples, the tendency is to choose perceptions whose content does not essentially involve time, but concern how things are at the moment they are perceived. This is true whether the cases are veridical (seeing a tree as a tree) or illusory (misperceiving the colour or spatial properties of an object). Less discussed, and arguably more complex and interesting cases do involve time as an essential element: perceiving movement, for example, or perceiving the order and (...) comparative duration of events. And, like other kinds of perception, time perception can involve illusions, such as the puzzling ‘stopped clock’ illusion. I want to suggest that these dynamic cases, and perhaps particularly those involving illusion, make a distinctive contribution to the direct realist/sense datum theory debate over perception, and they undermine a popular argument in favour of the objective passage of time, namely that passage is an ineliminable feature of our temporal experience.

AbstractAdvances in precision agriculture, driven by big data technologies and machine learning algorithms can transform agriculture by enhancing crop and livestock productivity and supporting faster and more accurate on and off-farm decision making. However, little is known about how PA can influence farmers’ sense of self, their skills and competencies, and the meanings that farmers ascribe to farming. This study is animated by scholarly commitment to social identity research, and draws from socio-cyber-physical systems research, domestication theory, and activity (...) class='Hi'>theory. This conceptualization of PA within these theoretical perspectives helps to render visible how big agricultural data and machine learning algorithms can affect meaning, doing, and being for US farmers. Through analysis of data from six focus group discussions and follow-up surveys with stakeholders across the PA value chain, this paper shows that PA tools can necessitate farmers to learn and develop new competencies such as flying drones and interpreting yield maps. At the same time, PA can shape new meaning of farm work and new expectation about a ‘good farmer’, changing what it means to be a ‘successful’ farmer from someone who is not only a data observer or data gatherer but also validators of PA models by using their local knowledge of agronomic and environmental phenomenon. We conclude that PA can alter social expectations about farming by reorienting the role of farmers. Policymakers and agriculture extension and outreach programmers can develop more socially relevant PA knowledge and innovation if they can attend to both new and traditional ‘good farmer’ identities.

Some twenty years ago, Bogen and Woodward challenged one of the fundamental assumptions of the received view, namely the theory-observation dichotomy and argued for the introduction of the further category of scientific phenomena. The latter, Bogen and Woodward stressed, are usually unobservable and inferred from what is indeed observable, namely scientific data. Crucially, Bogen and Woodward claimed that theories predict and explain phenomena, but not data. But then, of course, the thesis of theory-ladenness, which has it that our (...) observations are influenced by the theories we hold, cannot apply. On the basis of two case studies, I want to show that this consequence of Bogen and Woodward’s account is rather unrealistic. More importantly, I also object against Bogen and Woodward’s view that the reliability of data, which constitutes the precondition for data-to-phenomena inferences, can be secured without the theory one seeks to test. The case studies I revisit have figured heavily in the publications of Bogen and Woodward and others: the discovery of weak neutral currents and the discovery of the zebra pattern of magnetic anomalies. I show that, in the latter case, data can be ignored if they appear to be irrelevant from a particular theoretical perspective (TLI) and that, in the former case, the tested theory can be critical for the assessment of the reliability of the data (TLA). I argue that both TLI and TLA are much stronger senses of theory-ladenness than the classical thesis and that neither TLI nor TLA can be accommodated within Bogen and Woodward’s account. (shrink)

This paper examines folk theories of algorithmic recommendations on Spotify in order to make visible the cultural specificities of data assemblages in the global South. The study was conducted in Costa Rica and draws on triangulated data from 30 interviews, 4 focus groups with 22 users, and the study of “rich pictures” made by individuals to graphically represent their understanding of algorithmic recommendations. We found two main folk theories: one that personifies Spotify and another one that envisions it as a (...) system full of resources. Whereas the first theory emphasizes local conceptions of social relations to make sense of algorithms, the second one stresses the role of algorithms in providing a global experience of music and technology. We analyze why people espouse either one of these theories and how these theories provide users with resources to enact different modalities of power and resistance in relation to recommendation algorithms. We argue that folk theories thus offer a productive way to broaden understanding of what agency means in relation to algorithms. (shrink)

What is the nature of, and what is the relationship between, external objects and our visual perceptual experience of them? In this book, Frank Jackson defends the answers provided by the traditional Representative theory of perception. He argues, among other things that we are never immediately aware of external objects, that they are the causes of our perceptual experiences and that they have only the primary qualities. In the course of the argument, sense data and the distinction between mediate (...) and immediate perception receive detailed defences and the author criticises attempts to reduce perceiving the believing and to show that the Representative theory makes the external world unknowable. Jackson recognises that his views are unfashionable but argues in detail that they are to be preferred to their currently favoured competitors. It will become an obvious point of reference for all future work on the philosophy of perception. (shrink)

Machine learning (ML) refers to a class of computer-facilitated methods of statistical modelling. ML modelling techniques are now being widely adopted across the sciences. A number of outspoken representatives from the general public, computer science, various scientific fields, and philosophy of science alike seem to share in the belief that ML will radically disrupt scientific practice or the variety of epistemic outputs science is capable of producing. Such a belief is held, at least in part, because its adherents take ML (...) to exist on novel epistemic footing relative to classical mathematical or statistical modelling approaches utilised in science. Namely, they take modelling with ML to be a “theory-free” enterprise, in the sense of not resting essentially on input from human conceptual grasp on the target phenomenon and domain expertise. I take this view to arise from the further, and more deeply entrenched belief that data is worldly and objective; i.e., data is viewed as recapitulating or representing with perfect fidelity the structure or properties of the systems in nature it is sampled from. Yet most contemporary philosophers of science take on board, in one version or other, the thesis of theory-ladenness or theory-mediation of observation or measurement. From this, it follows that most philosophers of science (and, I will venture, many scientists) hold irreconcilable views on the nature of data, an internal tension which threatens the integrity of their appraisals of ML in science. Taking the thesis of theory-ladenness on board---and its implications for the nature of data seriously---it follows that there is no reason to believe that ML differs fundamentally in its epistemic footing from established mathematical modelling approaches in the sciences. I show that usage and interpretation can differ from “standard practice” in scientific projects which wield the tools of ML without accepting a difference in the epistemic or representational status of such tools.

There exists a venerable tradition of interdisciplinary research into the origins and development of Paleolithic cave painting. In recent years this research has begun to be inflected by rapid advances in measurement techniques that are delivering chronological data with unprecedented accuracy. Patterns are emerging from the accumulating evidence whose precise interpretation demands corresponding advances in theory. It seems that cave painting went through several transitions, beginning with the creation of simple lines, dots and disks, followed by hand stencils, then (...) by outlined figures, and finally by naturalistic figures. So far the most systematic evidence comes from Europe, although there are also indications that this sequence could be a universal pattern. The shamanic hypothesis provides a useful theoretical starting point because of its emphasis on the role of performance and phenomenology in the creative process. However, it still tends to reduce this sequence to mere stylistic and thematic changes that were external products of an already fully formed modern mind. Here I show how key insights from semiotics and material engagement theory can advance this explanatory framework to the extent that we become able to postdict the major transitions in the chronology of Paleolithic cave painting. An intriguing implication is that this is at the same time a chronology of cognitive changes, namely from a performative-phenomenological to a reflective-representational mind. (shrink)

Drawing on conservation of resources theory, this study examined how and when sense of control influence safety behavior. Linear regression analysis was performed on data collected from 481 students in 58 classes at a university. The results indicated that psychological stress mediated the negative effect of sense of control on safety compliance, as well as the positive effect of sense of control on safety participation. They further showed that perceptions of stronger safety regulations heightened the positive relationship between student (...) psychological stress and safety compliance, and buffered the negative effects of psychological stress on safety participation. These results provide a benchmark against which the effectiveness and relevance of epidemic prevention and control in higher education institutions can be assessed. (shrink)

Recent claims, mainly from computer scientists, concerning a largely automated and model-free data-intensive science have been countered by critical reactions from a number of philosophers of science. The debate suffers from a lack of detail in two respects, regarding the actual methods used in data-intensive science and the specific ways in which these methods presuppose theoretical assumptions. I examine two widely-used algorithms, classificatory trees and non-parametric regression, and argue that these are theory-laden in an external sense, regarding the framing (...) of research questions, but not in an internal sense concerning the causal structure of the examined phenomenon. With respect to the novelty of data-intensive science, I draw an analogy to exploratory as opposed to theory-directed experimentation. (shrink)

This book is a defence of a form of realism which stands closest to that upheld by the Nyãya-Vaid'sesika school in classical India. The author presents the Nyãya view and critically examines it against that of its traditional opponent, the Buddhist version of phenomenalism and idealism. His reconstruction of Nyãya arguments meets not only traditional Buddhist objections but also those of modern sense-data representationalists.
