Sense-Datum Theories

In this paper I consider the relationship between the spatial properties of visual perceptual experience and the sense-datum inference. I argue that the sense datum inference should be accepted if spatial properties are not merely intentionally present in such experiences. This result serves to underline the seriousness of the difficulties that are presented to direct realism by a particular class of illusory spatial experiences based on the geometry of visual perceptual experience. In light of these considerations I argue that it (...) is a constraint on direct realism that the underlying spatial character of visual perceptual experiences must be the same as that of the physical world.

This paper provides new tools for philosophical argument analysis and fresh empirical foundations for ‘critical’ ordinary language philosophy. Language comprehension routinely involves stereotypical inferences with contextual defeaters. J.L. Austin’s Sense and Sensibilia first mooted the idea that contextually inappropriate stereotypical inferences from verbal case-descriptions drive some philosophical paradoxes; these engender philosophical problems that can be resolved by exposing the underlying fallacies. We build on psycholinguistic research on salience effects to explain when and why even perfectly competent speakers cannot help making (...) stereotypical inferences which are contextually inappropriate. We analyse a classical paradox about perception (‘argument from illusion’), suggest it relies on contextually inappropriate stereotypical inferences from appearance-verbs, and show that the conditions we identified as leading to contextually inappropriate stereotypical inferences are met in formulations of the paradox. Three experiments use a forced-choice plausibility-ranking task to document the predicted inappropriate inferences, in English, German, and Japanese. The cross-linguistic study allows us to assess the wider relevance of the proposed analysis. Our findings open up new perspectives for ‘evidential’ experimental philosophy. (shrink)

Vision is organized around material objects; they are most of what we see. But we also see beams of light, depictions, shadows, reflections, etc. These things look like material objects in many ways, but it is still visually obvious that they are not material objects. This chapter articulates some principles that allow us to understand how we see these ‘ephemera’. H.P. Grice’s definition of seeing is standard in many discussions; here I clarify and augment it with a criterion drawn from (...) Fred Dretske. This enables me to re-analyse certain ephemera that have received counter-intuitive treatments in the work of Kendall Walton (photographs), Brian O’Shaughnessy (light), and Roy Sorenson (occlusions).

This is a critical study of C. I. Lewis' Epistemology and metaphysics from an original existential-phenomenological point of view. The study is critical of Lewis' sense-data theory, his implicit representationalism or phenomenalism, and his idea that meanings are essentially analytic definitions. The study is critical as well of Lewis' explanation of lived experience as a constructed result of given data on the one hand and chosen analytic definitions on the other, which are then to be composed into predictions stretching into (...) the future. The phenomonological viewpoint developed defends a basically direct understanding of the world and other persons and holds whole objects to be primary in perception. ;In the second half of the study Lewis' epistemological difficulties are traced to the basic ontology or world hypothesis which his view presupposes; this is found to be at odds with Lewis' own idea of metaphysical or categorial structures as pragmatic a priori adoptions. Considering our criticisms of Lewis' position, we are led to consider the question of the ultimate grounds from which one philosophical view may hope to criticize another, especially when each view rests on respectively different and conflicting categorial presuppositions. It is argued, in the end, that only a properly worked out phenomenological account of experience, thinking, and especially persons in relation , may enable one to make intelligible the possibility of philosophical systems in conflict at all. ;The study includes, in contrast to C. I. Lewis' presupposed world hypothesis, a sketch of the uniquely different world hypothesis which an existential-phenomenological point of view presupposes. (shrink)

This paper aims to show how some of Wittgenstein's considerations in the Philosophical Investigations speak to the neo-empiricist tendency to give sensation a purely causal, non-epistemic role. As the foil for Wittgenstein's criticisms, I outline the way Wilfred Sellars rehabilitates sensory impressions from his own diagnosis of the Myth of the Given by construing them as purely causal episodes. Sellars' work shows how it is possible to have a keen appreciation of the incoherence of the empiricist model yet to believe (...) that we ought to maintain that model by modifying our account of the role that sensations play in perception. Sellars and Wittgenstein have the same understanding of what a non-epistemic conception of sensations must involve. Wittgenstein articulates the way this conception manifests itself in ordinary thinking while Sellars gives it a sophisticated theoretical elaboration designed to retain what is key for sensory episodes while avoiding traditional problems of givenness. The instructive difference between Sellars and Wittgenstein is that while Sellars believes we can develop a coherent non-epistemic conception, Wittgenstein’s work suggests that we cannot. (shrink)

William Alston claimed that epistemic considerations are relevant to theorizing about the metaphysics of perceptual experience. There must be something about the intrinsic nature of a perceptual experience that explains why it is that it justifies one in believing what it does, rather than other propositions. A metaphysical theory of experience that provides the resources for such an explanation is to be preferred over ones that do not. Alston argued that the theory of appearing gains a leg up on its (...) rivals, particularly sense-datum theory and adverbialism, precisely on this score. This paper examines these claims, along with the further question of whether the theory of appearing fares better epistemologically than the currently popular theory of intentionalism about perceptual experience. I conclude that while Alston is correct that the theory of appearing fares better than its traditional rivals, it does not clearly fare better than intentionalism. I further argue that Alston ignores a number of complexities in his account of how perceptual experience, construed as states of objects appearing certain ways to subjects, justifies perceptual beliefs.

In this paper, I present the discussion between Ayer and Austin about whether sentences or utterances can be incorrigible and I argue in favor of Austin position. I defend Austin against objections from Ayer presented after the publication of Sense & Sensibilia. Unlike what was sustained by Ayer, experiential sentences and material object sentences are not epistemically asymmetrical. A material object sentence can be incorrigible if uttered in appropriated circumstances, and an experiential sentence can be corrigible if uttered in unappropriated (...) circumstances. Relying on Austin position, I argue that self-knowledge does not have any epistemic privilege in relation to knowledge of the external world. These kinds of knowledge equally depend on objective circumstances of the utterance situation. (shrink)

Tomamos como certo que os nossos sentidos nos colocam em contato com o ambiente ao nosso redor. Enquanto caminhamos em uma rua, vemos obstáculos que temos de contornar ou remover. Mesmo de costas, podemos ouvir a bicicleta que se aproxima e dar passagem. Em suma, por meio de experiências perceptivas (visuais, auditivas, olfativas etc.), ficamos conscientes de objetos ou eventos que estejam ocorrendo ao nosso redor. Além disso, com base no que percebemos, podemos formar e manter crenças acerca do ambiente (...) e, assim, adquirir conhecimento perceptivo acerca do mundo. A importância desse conhecimento acerca do que está ao nosso alcance perceptivo é inestimável para a nossa sobrevivência e a condução de nossos projetos cotidianos. Contudo, podemos querer saber (1) se de fato temos acesso ao mundo físico circundante por meio das nossas experiências perceptivas, e (2) se e como essas experiências justificam as nossas crenças acerca do que percebemos. Esses problemas são centrais para a epistemologia da percepção, embora não sejam os únicos. Nessa entrada, abordaremos esses dois problemas. (shrink)

I argue that the familiar picture of the rise of analytic philosophy through the early work of G. E. Moore and Bertrand Russell is incomplete and to some degree erroneous. Archival evidence suggests that a considerable influence on Moore, especially evident in his 1899 paper ‘The nature of judgment,’ comes from the literature in nineteenth-century empirical psychology rather than nineteenth-century neo-Hegelianism, as is widely believed. I argue that the conceptual influences of Moore’s paper are more likely to have had their (...) source in the work of two of Moore’s teachers, G. F. Stout and James Ward. What may be called an anti-psychologism about psychology characterizes the work of these and other psychologists of the period. I argue that the anti-psychologism that is the main aim of Moore’s early theory of judgment is an adaptation of this notion, which is significantly dissimilar from the notion defended by Bradley, traditionally thought to have been a key influence on Moore.Keywords: G. E. Moore; Bertrand Russell; Propositions; Anti-psychologism; Early analytic philosophy; G. F. Stout. (shrink)

_Philosophical Delusion and its Therapy_ provides new foundations and methods for the revolutionary project of philosophical therapy pioneered by Ludwig Wittgenstein. The book vindicates this currently much-discussed project by reconstructing the genesis of important philosophical problems: With the help of concepts adapted from cognitive linguistics and cognitive psychology, the book analyses how philosophical reflection is shaped by pictures and metaphors we are not aware of employing and are prone to misapply. Through innovative case-studies on the genesis of classical problems about (...) the mind and perception, and on thinkers including Locke, Berkeley and Ayer, the book demonstrates how such autonomous habits of thought systematically generate unsound intuitions and philosophical delusions, whose clash with reality, or among each other, gives rise to ill-motivated but maddening problems. The book re-examines models of therapeutic philosophy, due to Wittgenstein and J. L. Austin, and develops an approach that may let us overcome philosophical delusions and the problems they engender. In this way, the book explains where and why therapy in called for in philosophy, and develops techniques to carry it out. (shrink)

Whether perceptual experience represents high-level properties like causation and natural-kind in virtue of its phenomenology is an open question in philosophy of mind. While the question of high-level properties has sparked disagreement, there is widespread agreement that the sensory phenomenology of perceptual experience presents us with low-level properties like shape and color. This paper argues that the relationship between the sensory character of experience and the low-level properties represented therein is more complex than most assume. Careful consideration of mundane examples, (...) like looking at a coin from an oblique angle, show that the low-level properties represented in experience do not necessarily figure in the sensory character of the experience. Furthermore, the sensible properties invoked when characterizing the sensory character of a perceptual experience are not necessarily included in the sensible properties represented in a perceptual experience. On this basis it is argued that perceptual experience has a disunified metaphysics, consisting in distinct sensory and cognitive components. The account is developed in relation to existing unified and disunified accounts, and discussed in terms of its implications for cognitive penetration, the reliability of introspection, the transparency of experience, and cognitive phenomenology.

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.

This paper discuss the problem of motion within sense-data concept. Using the sense of speed as starting-point, we debate how it is possible to find a conceptual formulation that combines the idea of mental states with its physicalist criticism. The answer lies in the field of quantum mechanics and its concept of tensor, a geometric object that has a mathematical matrix representation. Thinking about examples taken from the car racing world, where the sense of speed is preponderant, we see how (...) the mental condition of speed is represented matrix-like, tensor-like, rather than ephemerally as the more traditional sense-data formulation advocates.

There exists a problem of the circularity in measurement: construction of theories requires reliable data, but obtaining reliable data requires reliable measurement devices whose construction requires a theory. I argue that adapting Anil Gupta's empiricist epistemology to a scientific context yields a possible solution. One can consider the role of data not as providing a foundation for a theory, but as acting functionally, licensing revisions of a previous theory. Data provide scientists with entitlement to their claims conditional on their background (...) theory. Unconditional entitlement is obtained when different starting theories converge to the same view over the course of experimentation. I explain this idea using two examples, one in thermometry and one involving experiments on the weak neutral current. (shrink)

By all indications, the popularity of the Sense-Datum Theory is definitely on the wane. This once-proud theory, which was perhaps the most characteristic feature of British Philosophy during the first half of this century, has been attacked from so many different sides that even its foremost protagonists have either accepted the very watered-down version according to which it is just an alternative language for speaking about the facts of perception or else they hold their peace and let the youngsters play. (...) There are still some diehards who carry on as if nothing had happened, but they are an insignificant minority. (shrink)

A working theory can involve a compromise between pragmatic application and pure theory. This is illustrated by the development of Coombs's theory of data. The original version of the theory purported to guide investigators in the use of scaling techniques, but subsequent revisions including a logico-mathematical statement of the theory do not show whether the practical recommendations made earlier still apply. These practical recommendations, some of which Coombs has discarded to obtain a comprehensive theory, are important in spite of shortcomings (...) as they reveal differences between attitude and mental test data. The different forms of Coombs's theory point to the existence of a general problem, how to find a compromise between practice and pure theory. (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).

The aim of this thesis is to study a dispute between J. L. Austin and A. J. Ayer, and in so doing consider the relevance of a linguistic investigation for philosophy. The dispute is confined for the most part to Austin's criticisms of the sense-datum theory, particularly as it has been supported by the argument from illusion, in Sense and Sensibilia and Ayer's reply to these in "Has Austin Refuted the Sense-Datum Theory?" . The argument from illusion is a traditional (...) philosophical argument whereby incidents of non-veridical perception, e.g., the partly immersed stick that looks bent, are taken to support the claim that we do not perceive material objects, but must perceive something else, i.e., sense-data. In S&S; , Austin contends that the argument is typically philosophical because it over-simplifies and misrepresents the facts of ordinary language and normal perception. In ARS, Ayer replies that the argument is essentially philosophical because it is logical and not factual: it shows that the truth of a material object statement is never entailed by the truth of the experiential statement upon which it is based. The Austin-Ayer dispute is best characterized as a clash of philosophical vision, that is, as a conflict about the proper aim and method of a philosophical investigation, and the role of an "analysis of language" for philosophy. This thesis, then, sets out to describe the philosophical vision of Austin and Ayer, to show how the criticisms that are offered by each philosopher are informed by their respective philosophical viewpoints, and to establish that each philosopher presupposes the legitimacy of his own method in criticizing the other. As a result, the arguments that each philosopher makes in defence of his position are seen as begging the question by presuming the validity of the claims that they must establish. (shrink)
