In this paper I argue that Wittgenstein's aim in the aspect-perception passages is to critically evaluate a specific hypothesis. The target hypothesis in these passages is the Gestalt psychologist Köhler's "isomorphism principle." According to this principle, there are neural correlates of conscious perceptual experience, and these neural correlates determine the content of our perceptual experiences. Wittgenstein's argument against the isomorphism principle comprises two steps. First, he diffuses the substantiveness of the principle by undermining an important assumption that underpins this principle, (...) namely, that there is a unitary concept of seeing. Next, Wittgenstein argues that some forms of aspect-perception involve recognitional capacities, the exercise of which is normatively constrained. The normative nature of aspect-perceiving plays a pivotal role in Wittgenstein's rejection of the isomorphism principle. Aside from the clear exegetical benefits gained from identifying the target hypothesis in the aspect-perception passages as the isomorphism principle, construing the remarks in the way suggested here is also philosophically interesting in its own right: it shows Wittgenstein engaging directly in the mind–body problem, construed as the problem of intentionality.

The Cambridge History of Philosophy 1870-1945 comprises over sixty specially commissioned essays by experts on the philosophy of this period, and is designed to be accessible to non-specialists. The first part of the book traces the history of philosophy from its remarkable flowering in the 1870s through to the early years of the twentieth century. After a brief discussion of the impact of the First World War, the second part of the book describes further developments in philosophy in the first (...) half of the twentieth century. The essays concentrate on developments across the range of philosophical topics, from logic and metaphysics to political philosophy and philosophy of religion. This volume will be of critical importance not only to teachers and students of philosophy but also to scholars in neighbouring disciplines such as the history of science, the history of ideas, theology and the social sciences.

The problem of amodal perception is the problem of how we represent features of perceived objects that are occluded or otherwise hidden from us. Bence Nanay (2010) has recently proposed that we amodally perceive an object's occluded features by imaginatively projecting them into the relevant regions of visual egocentric space. In this paper, I argue that amodal perception is not a single, unitary capacity. Drawing appropriate distinctions reveals amodal perception to be characterized not only by mental imagery, as Nanay suggests, (...) but also by genuinely visual representations as well as beliefs. I conclude with some brief remarks on the role of object-directed bodily action in conferring a sense of unseen presence on an object's occluded features. (shrink)

In this paper, I critically assess the enactive account of visual perception recently defended by Alva Noë (2004). I argue inter alia that the enactive account falsely identifies an object’s apparent shape with its 2D perspectival shape; that it mistakenly assimilates visual shape perception and volumetric object recognition; and that it seriously misrepresents the constitutive role of bodily action in visual awareness. I argue further that noticing an object’s perspectival shape involves a hybrid experience combining both perceptual and imaginative elements (...) – an act of what I call ‘make-perceive.’. (shrink)

While much of Arne Naess’s ecosophy underscores the importance of understanding one’s ecological Self, his analyses of gestaltism are significant in that they center less on questions of the self than on questions of nature and what is other-than-human. Rather than the realization of a more expansive Self, gestalt ontology calls for a “gestalt shift” in our thinking about nature, one that allows for its intrinsic value to emerge clearly. Taking such a gestalt shift as a central task enables Naess (...) to avoid some common criticisms of his view. (shrink)

We present select examples of how visual phenomena can serve as tools to uncoverbrain mechanisms. Specifically, receptive field organization is proposed as a Gestalt-like neural mechanism of perceptual organization. Appropriate phenomena, such as brightness and orientation contrast, subjective contours, filling-in, and aperture-viewed motion, allow for a quantitative comparison between receptive fields and their psychophysical counterparts, perceptive fields. Phenomenology might thus be extended from the study of perceptual qualities to their transphenomenal substrates, including memory functions. In conclusion, classic issues of Gestalt (...) psychology can now be related to modern. (shrink)

The Gestalt psychologists adopted a set of positions on mind-body issues that seem like an odd mix. They sought to combine a version of naturalism and physiological reductionism with an insistence on the reality of the phenomenal and the attribution of meanings to objects as natural characteristics. After reviewing basic positions in contemporary philosophy of mind, we examine the Gestalt position, characterizing it m terms of phenomenal realism and programmatic reductionism. We then distinguish Gestalt philosophy of mind from instrumentalism and (...) computational functionalism, and examine Gestalt attributions of meaning and value to perceived objects. Finally, we consider a metatheoretical moral from Gestalt theory, which commends the search for commensurate description of mental phenomena and their physiological counterparts. (shrink)

Teaching ethics poses a dilemma for professors of business. First, they have little or no formal training in ethics. Second, they have established ethical values that they may not want to impose upon their students. What is needed is a well-recognized, yet non-sectarian model to facilitate the clarification of ethical questions. Gestalt theory offers such a framework. Four Gestalt principles facilitate ethical clarification and another four Gestalt principles anesthetize ethical clarification. This article examines each principle, illustrates that principle through current (...) business examples, and offers exercises for developing each principle. (shrink)

In the present article, the role of Gestalt concepts in clarifying the issues of perception is evaluated. Grounded in anti-atomism, Gestalt assumed organizing forces intrinsic to perception. Insofar these were identified with singularity preference, Gestalt is criticized for having failed to distinguish between perception and thought.

A serious crisis is identified in theories of neurocomputation, marked by a persistent disparity between the phenomenological or experiential account of visual perception and the neurophysiological level of description of the visual system. In particular, conventional concepts of neural processing offer no explanation for the holistic global aspects of perception identified by Gestalt theory. The problem is paradigmatic and can be traced to contemporary concepts of the functional role of the neural cell, known as the Neuron Doctrine. In the absence (...) of an alternative neurophysiologically plausible model, I propose a perceptual modeling approach, to model the percept as experienced subjectively, rather than modeling the objective neurophysiological state of the visual system that supposedly subserves that experience. A Gestalt Bubble model is presented to demonstrate how the elusive Gestalt principles of emergence, reification, and invariance can be expressed in a quantitative model of the subjective experience of visual consciousness. That model in turn reveals a unique computational strategy underlying visual processing, which is unlike any algorithm devised by man, and certainly unlike the atomistic feed-forward model of neurocomputation offered by the Neuron Doctrine paradigm. The perceptual modeling approach reveals the primary function of perception as that of generating a fully spatial virtual-reality replica of the external world in an internal representation. The common objections to this picture-in-the-head concept of perceptual representation are shown to be ill founded.

Neurophysiological investigations of the visual system by way of single-cell recordings have revealed a hierarchical architecture in which lower level areas, such as the primary visual cortex, contain cells that respond to simple features, while higher level areas contain cells that respond to higher order features apparently composed of combinations of lower level features. This architecture seems to suggest a feed-forward processing strategy in which visual information progresses from lower to higher visual areas. However there is other evidence, both neurophysiological (...) and phenomenal, that suggests a more parallel processing strategy in biological vision, in which top-down feedback plays a significant role. In fact Gestalt theory suggests that visual perception involves a process of emergence, i.e. a dynamic relaxation of multiple constraints throughout the system simultaneously, so that the final percept represents a stable state, or energy minimum of the dynamic system as a whole. A Multi-Level Reciprocal Feedback (MLRF) model is proposed to resolve the apparently contradictory concepts, by proposing a hierarchical visual architecture whose different levels are connected by bi-directional feed-forward and feedback pathways, where the computational transformation performed by the feedback pathway between levels in the hiararchy is a kind of inverse of the transformation performed by the corresponding feed-forward processing stream. This alternative paradigm of perceptual computation accounts in general terms for a number of visual illusory effects, and offers a computational specification for the generative, or constructive aspect of perceptual processing revealed by Gestalt theory.

It is a characteristic feature of our mental make-up that the same perceptual input situation can simultaneously elicit conflicting mental perspectives. This ability pervades our perceptual and cognitive domains. Striking examples are the dual character of pictures in picture perception, pretend play, or the ability to employ metaphors and allegories. I argue that traditional approaches, beyond being inadequate on principle grounds, are theoretically ill equipped to deal with these achievements. I then outline a theoretical perspective that has emerged from a (...) theoretical convergence of perceptual psychology, ethology, linguistics, and developmental research. On the basis of this framework, I argue that corresponding achievements are brought forth by a specific type of functional architecture whose core features are as follows: (1) a perceptual system that is biologically furnished with a rich system of conceptual forms, (2) a triggering relation between the sensory input and conceptual forms by which the same sensory input can be exploited by different types or systems of conceptual forms, and (3) computational principles for handling semantically underspecified conceptual forms. Characteristic features of the proposed theoretical framework are pointed out using the Heider–Simmel phenomenon as an example. (shrink)

This article explores the evolution of human attention, focusing particularly on the phylogenetic and ontogenetic implications of the work of the American social psychiatrist Trigant Burrow. Attentional development is linked to the emergence of visual perspective, and this, in turn, is related to Burrow's notion of `ditention' (divided or partitive attention). Burrow's distinction between `ditention' and `cotention' (total organismic awareness) is examined, and, expanding on this, a threefold pattern of perceptual change is identified: prototention-->ditention-->cotention. Next, ditentive visual perspective is related (...) to binocular convergence, and the author makes use of the perspectivally ambiguous, `non-convergent' Gestalt figure known as the Necker Cube to illustrate cotention. The paper concludes by proposing that the shift from the currently pervasive ditentive pattern of awareness to a cotentive mode could have a salutary effect on human society. (shrink)

In seeking an interpretation of the theory of Gestalt, the analysis revealed that the concept of Gestalt applies to processes and particularly to the way in which events or processes take place. The essential condition for the emergence of Gestalten or configurational properties was found to be—the ability of the parts or factors in the process to influence each other. In considering first, the more dynamic or formative phase of processes, the significant factors which influence the reciprocity of influence between (...) the parts or factors of the process were found to be (i) the properties of the individual parts or factors, (ii) the properties of the intervening medium, (iii) the 'distance' between the parts or factors, (vi) 'factors of rigidity or constraint'. It was emphasised that these factors operate relatively to one another. The concept of 'wholeness' was found to apply to both the dynamic and the more static phase of the process. The resultant or equilibrium position of the process derives some contribution from the whole matrix of interacting factors or influences which are responsible for the resultant being precisely what it is. The recognition of the causal significance of even small contributions to an event or process is consistent with the concept of 'wholeness' and with the 'matrix' view of causal explanation. This view of causal explanation is the consistent implication of the theory of Gestalt and the many experimental results associated with this school. (shrink)

Gestalt theory is discussed as one main precursor of synergetics, one of the most elaborated theories of self-organization. It is a precursor for two reasons: the Gestalt theoretical view of cognitive order-formation comes dose to the central ideas of self-organization. Furthermore both approaches have stressed the significance of non-linear perceptual processes (such as multistability) for the solution of the mind-brain problem. The question of whether Gestalt theory preferred a dualistic or a monistic view of the mind-body relation is answered in (...) that there was a preference for dualism in epistemological questions and for monism in the mind-brain relation. The latter was attained by the concept of psychophysical isomorphism. This concept, although widely misunderstood in many respects, was criticized on the basis of neurobiological findings. One main objection was the neglect of the importance of the elementary neurophysiological processes. A distinction between macroscopic and microscopic brain processes seemed to be required. This idea was taken up in synergetics which postulates a bottom-up and top-down interaction between these two levels. Macroscopic order emerges from elementary brain processes and, at the same time, has a backward slaving effect to the microscopic level In the light of such holistic emergentism, the question whether macroscopic order states might be attractors for psychological meanings is discussed.

This discussion takes up an attack by Jerrold Aronson (seconded by Rom Harre) on the use made by Norwood R. Hanson of the Gestalt-Switch Analogy in the philosophy of science. Aronson's understanding of what is implied in a gestalt switch is shown to be flawed. In his endeavor to detach conceptual understanding from perceptual identification he cites several examples, without realizing the degree to which such gestalt switches can affect conceptualizing or how conceptualizing can affect gestalts. In particular, he has (...) not confronted the possibility of such gestalt selection being involved in the basic identification of what we term "entities". (shrink)

A review of the scanty Gestaltist literature on motor behaviour indicates that a genuine Gestalt theoretic approach to motor behaviour can be characterized by three research questions: (1) What are the natural units of motor behaviour? (2) What characterizes the self-organization in motor behaviour? (3) What are the conditions for invariance in motor behaviour? Tentative answers to these questions can be found by analysing the parallels between Gestalt theory and Bernstein's theory of motor actions and by showing that Gestalt theory (...) can be regarded as a specific approach to non-linear dynamics as exemplified by synergetics (Haken, 1991). The congruence between the Gestalt theoretic approach and synergetics becomes apparent in the analysis of how a complex motor task is learned [1]. (shrink)
