A comparison of disjunctive theories of action and perception. The development of a theory of action that warrants the name, a disjunctive theory. On this theory, there is an exclusive disjunction: either an action or an event (in one sense). It follows that in that sense basic actions do not have events intrinsic to them.

Recently, the relationship between evolutionary ecology and perceptual science has received renewed attention under perception-mediated selection, a mode of natural selection linking perceptual saliency, rather than veridicality, to fitness. The Interface Theory of Perception (ITP) has been especially prominent in claiming that an organism’s perceptual interface is populated by icons, which arise as a function of evolved, species-specific perceptual interfaces that produce approximations of organisms’ environments through fitness-tuned perceptions. According to perception-mediated selection, perception and behavior calibrate (...) one another as organisms’ capacities to experience and know the objects and properties of their environments lead to responses highlighting certain environmental features selected for survival. We argue this occurs via the Umwelt/Umgebung distinction in ethology, demonstrating that organisms interact with their external environments (Umgebung) through constructed perceptual schema (Umwelt) that produce constrained representations of environmental objects and their properties. Following Peircean semiotics, we claim that ITP’s focus on icons as saliency-simplified markers corresponds to biosemiotics’ understanding of perceptual representations, which manifest as iconic (resembling objects), indexical (referring), or symbolic (arbitrary) modalities, which provide for organisms’ semiotic scaffolding. We argue that ITP provides the computational evidence for biosemiotics’ notion of iconicity, while biosemiotics provides explanation within ITP for how iconicity can build up into indices and symbols. The common contention of these separate frameworks that the process of perception tracks saliency rather than veridicality suggests that digital/dyadic perceptual strategies will be outcompeted by their semiotic/triadic counterparts. This carries implications for evolutionary theory as well as theories of cognition. (shrink)

Some argue that Candrakīrti is committed to rejecting all theories of perception in virtue of the rejection of the foundationalisms of the Nyāya and the Pramāṇika. Others argue that Candrakīrti endorses the Nyāya theory of perception. In this paper, I will propose an alternative non-foundationalist theory of perception for Candrakīriti. I will show that Candrakrti’s works provide us sufficient evidence to defend a typical Prāsagika’s account of perception that, I argue, complements his core non-foundationalist ontology.

This essay explains Donald Hoffman's Interface Theory of Perception using The Biological Framework for a Mathematical Universe proposed by Ronald Williams. According to Hoffman, what we perceive is more like a “desktop interface with icons representing complex underlying processes, rather than a direct window into the true nature of the world." The theory of a biological framework for a mathematical universes suggests that these complex underlying processes of “the desktop interface with icons” contain correspondences to biological systems. For example, (...) “the desktop icons” of the ocean’s arctic currents and the melting and freezing of Antartica contain “complex underlying processes” which mirror the processes of a circulatory system and beating heart. While indeed we do interpret reality from a superficial perspective as Hoffman suggests, our cognitive abilities are enhanced enough to recognize correspondences to these patterns pertaining to these biological systems which reveal the true nature of the world/universe/reality and thus highlight our evolved perceptual systems which can enable us how to recognize these patterns and organize ourselves to them in order to best survive it. Another example of a “desktop icon” is human society—the order and properties of human society contain “complex underlying processes” that are analogous to the order and properties of cellular society—thus “socioeconomic problems” can be understood through cellular economic problems. Moreover, the solution to the cellular economic problem is the solution to the socioeconomic problem. (shrink)

Plato’s Theory of Perception This research deals with Plato's perceptual theory, as the perceptual theory in Plato's philosophy represents one of the steps of the Plato’s epistemology. Plato divided knowledge into four categories: Sensory knowledge, presumptive knowledge, mathematical knowledge, and rational knowledge. The theory of sensory perception is in the first place, so this research focuses on the statements, the meaning of perception, the senses, the difference between sensation and mind, the topics of sensory perception, and (...) the nature of the work of sensory perception.

ABSTRACT: The Reflexive Theory of Perception (RTP) claims that perception of an object or property X by an organism Z consists in Z being caused by X to acquire some disposition D toward X itself. This broadly behavioral perceptual theory explains perceptual intentionality and correct versus incorrect, plus successful versus unsuccessful, perception in a plausible evolutionary framework. The theory also undermines cognitive and perceptual modularity assumptions, including informational or purely epistemic views of perception in that, according (...) to the RTP, any X-caused and X-directed dispositions are genuinely perceptual—including affective, attitudinal, and immediately activated purely action-directed behavioral dispositions. Thus the RTP has the potential to provide the foundations for a broadly behavioral counter-revolution in cognitive science. (shrink)

In this paper, I assess John McDowell's paper "Avoiding the Myth of the Given" (2009) (AMG) and its theory of epistemological openness to the world. I trace its motivations back to Kantian, Sellarsian and Aristotelean roots. I argue that McDowell subscribes to a kind of Holistic Theory of Rationality (HTR). To explain the HTR, I will analyze the Sellarsian notions of the "Manifest Image," the "Myth of the Given" and the "logical space of reasons." I argue that the holistic nature (...) of McDowell's theory gives it particular properties that put it in need of conservatism, because all the elements of the theory "hang together" - i.e. cohere - in a dangerous fashion. I argue that McDowell cannot afford big changes without upsetting the apple-cart. With this in mind, I shall assess the merits and demerits of AMG, and its modified theory of perceptual content, as an attempted conservative reform of HTR. I want to argue that, taken independently, AMG is a good and important change, but taken holistically it is non-conservative, and disruptive, of the McDowellian picture. Thus, if we wish to proceed with the McDowellian path, we are led to a choice between rejecting the local reform (and retreating back to an earlier version) or demanding further explanations of its global implications.

It has become typical to read Kant and Merleau-Ponty as offering competing approaches to perceptual experience. Kant is interpreted as an ‘intellectualist’ who regards perception as conceptual ‘all the way out’, while Merleau-Ponty is seen as Kant’s challenger, who argues that perception involves non-conceptual, embodied ‘coping’. In this paper, however, I argue that a closer examination of their views of perception, especially with respect to the notion of ‘schematism’, reveals a great deal of historical and philosophical continuity (...) between them. By analyzing Kant’s theory of schematism, the interpretation of it by the Neo-Kantian Pierre Lachièze-Rey, and Merleau-Ponty’s theory of the body schema, we find that aspects of Merleau-Ponty’s theory of perception are better understood as a development of Kant’s theory of perception.

It is widely held by philosophers not only that there is a causal condition on perception but also that the causal condition is a conceptual truth about perception. One influential line of argument for this claim is based on intuitive responses to a style of thought experiment popularized by Grice. Given the significance of these thought experiments to the literature, it is important to see whether the folk in fact respond to these cases in the way that philosophers (...) assume they should. We test folk intuitions regarding the causal theory of perception by asking our participants to what extent they agree that they would ‘see’ an object in various Gricean scenarios. We find that the intuitions of the folk do not strongly support the causal condition; they at most strongly support a ‘no blocker’ condition. We argue that this is problematic for the claim that the causal condition is a conceptual truth. (shrink)

In his book “Galileo’s Error”, Philip Goff lays out what he calls “foundations for a new science of consciousness”, which are decidedly anti-physicalist (panpsychist), motivated by a critique of Galileo’s distinction into knowable objective and unknowable subjective properties and Arthur Eddington’s argument for the limitation of purely structural (physical) knowledge. Here we outline an alternative theory, premised on the Interface Theory of Perception, that too subscribes to a “post-Galilean” research programme. However, interface theorists disagree along several lines. 1. They (...) note that Galileo’s distinction should be replaced by a truly non-dual account, referring to a difference of degree only. 2. They highly appreciate the role of mathematics, in particular when it comes to actually engage scientifically with consciousness. Some notable features of the interface theory are its skepticism towards our epistemic capacities and its rejection of the existence of a public, mind-independent reality. In addition, some interface theorists further employ a thin concept of “conscious agency” to ground their theory. The interface theory leaves open many of the problems of consciousness science (e.g. what is a “self”?) as questions for further (scientific, mathematical) research. (shrink)

Much mainstream analytic epistemology is built around a sceptical treatment of modality which descends from Hume. The roots of this scepticism are argued to lie in Hume’s (nominalist) theory of perception, which is excavated, studied and compared with the very different (realist) theory of perception developed by Peirce. It is argued that Peirce’s theory not only enables a considerably more nuanced and effective epistemology, it also (unlike Hume’s theory) does justice to what happens when we appreciate a proof (...) in mathematics.

Disjunctivist views in the theory of perception hold that genuine perceptions differ in some relevant kind from misperceptions, such as illusions and hallucinations. In recent papers, Tyler Burge has argued that such views conflict with the basic tenets of perceptual psychology. According to him, perceptual psychology is committed to the view that genuine perceptions and misperceptions produced by the same proximal stimuli must be or involve perceptual states of the same kind. This, he argues, conflicts with disjunctivism. In this (...) paper, I defend epistemological disjunctivism from Burge’s inconsistency charge. To this end, I survey the perceptual psychological literature, and reveal that the perceptual kinds they tend to employ differ from and imply nothing about the kinds at issue for the epistemological disjunctivist. I then argue that Burge’s concerns with epistemological disjunctivism are best interpreted as motivated not by his commitment to empirical science, but instead by his views in epistemology and about human rationality.

According to the phenomenological argument for disjunctivism, the reasons why we should prefer the disjunctive theory over its rivals is that (1) the disjunctive theory conforms the most to our pretheoretical or natural convictions about perception (what Michael Martin calls naïve realism), and (2) we should commit ourselves to naïve realism because it conforms the most to the phenomenology of the perceptual experience of objects. In this paper, I try to explain why is the phenomenal argument exceptionally strong argument (...) for disjunctivism and at the same time against sense-datum and intentional theories. Furthermore, I try to show that the disjunctivist’s explanation of hallucination (which is allegedly the weak point of the theory) is as plausible as its rivals’. (shrink)

Review of THEO C. MEYERING, Historical Roots of Cognitive Science : The Rise of a Cognitive Theory of Perception from Antiquity to the Nineteenth Century. Boston: Kluwer, xix + 250 pp. $69.00. Examines the author's interpretation of Aristotelian theories of perceptual cognition, early modern theories, and Helmholtz's theory.

As so often in philosophy, the title not only lays down the battle line but exposes the author’s biases and mistakes, since whether or not we can make sense of the language game ‘Seeing things as they are’ and whether it’s possible to have a ‘philosophical’ ‘theory of perception’ (which can only be about how the language of perception works), as opposed to a scientific one, which is a theory about how the brain works, are exactly the issues. (...) This is classic Searle—superb and probably at least as good as anyone else can produce, but lacking a full understanding of the fundamental insights of the later Wittgenstein and with no grasp of the two systems of thought framework, which could have made it brilliant. As in his previous work, Searle largely avoids scientism but there are frequent lapses and he does not grasp that the issues are always about language games, a failing he shares with nearly everyone. After providing a framework consisting of a Table of Intentionality based on the two systems of thought and thinking and decision research, I give a detailed analysis of the book. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

What do we see when we look at someone's expression of fear? I argue that one of the things that we see is fear itself. I support this view by developing a theory of affect perception. The theory involves two claims. One is that expressions are patterns of facial changes that carry information about affects. The other is that the visual system extracts and processes such information. In particular, I argue that the visual system functions to detect the affects (...) of others when they are expressed in the face. I develop my theory by drawing on empirical data from psychology and brain science. Finally, I outline a theory of the semantics of affect perception. (shrink)

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean-style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a clock and (...) brain stimulation). They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean-style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

Introduction & Objectives: Norwich’s Entropy Theory of Perception (1975 [1] -present) stands alone. It explains many firing-rate behaviors and psychophysical laws from bare theory. To do so, it demands a unique sort of interaction between receptor and brain, one that Norwich never substantiated. Can it now be confirmed, given the accumulation of empirical sensory neuroscience? Background: Norwich conjoined sensation and a mathematical model of communication, Shannon’s Information Theory, as follows: “In the entropic view of sensation, magnitude of sensation is (...) regarded as a measure of the entropy or uncertainty of the stimulus signal” [2]. “To be uncertain about the outcome of an event, one must first be aware of a set of alternative outcomes” [3]. “The entropy-establishing process begins with the generation of a [internal] sensory signal by the stimulus generator. This is followed by receipt of the [external] stimulus by the sensory receptor, transmission of action potentials by the sensory neurons, and finally recapture of the [response to the internal] signal by the generator” [4]. The latter “recapture” differentiates external from internal stimuli. The hypothetical “stimulus generators” are internal emitters, that generate photons in vision, audible sounds in audition (to Norwich, the spontaneous otoacoustic emissions [SOAEs]), “temperatures in excess of local skin temperature” in skin temperature sensation [4], etc. Method (1): Several decades of empirical sensory physiology literature was scrutinized for internal “stimulus generators”. Results (1): Spontaneous photopigment isomerization (“dark light”) does not involve visible light. SOAEs are electromechanical basilar-membrane artefacts that rarely produce audible tones. The skin’s temperature sensors do not raise skin temperature, etc. Method (2): The putative action of the brain-and-sensory-receptor loop was carefully reexamined. Results (2): The sensory receptor allegedly “perceives”, experiences “awareness”, possesses “memory”, and has a “mind”. But those traits describe the whole human. The receptor, thus anthropomorphized, must therefore contain its own perceptual loop, containing a receptor, containing a perceptual loop, etc. Summary & Conclusions: The Entropy Theory demands sensory awareness of alternatives, through an imagined brain-and-sensory-receptor loop containing internal “stimulus generators”. But (1) no internal “stimulus generators” seem to exist and (2) the loop would be the outermost of an infinite nesting of identical loops. (shrink)

The condition of ‘genuine perceptual synaesthesia’ has been a focus of attention in research in psychology and neuroscience over the last decades. For subjects in this condition stimulation in one modality automatically and consistently over the subject’s lifespan triggers a percept in another modality. In hearing→colour synaesthesia, for example, a specific sound experience evokes a perception of a specific colour. In this paper, I discuss questions and challenges that the phenomenon of synaesthetic experience raises for theories of perceptual (...) experience in general, and for theories thatsee the content and modality of conscious experience as being constituted and determined by the active and skilful exploration of the environment in particular. The focus of my paper will be on the latter, ‘enactive’ view of perception and its theory of what determines the modality-specific ‘feel’ of a perceptual experience. (shrink)

This paper examines the evolution of Husserl’s philosophy of nonintuitive intentions. The analysis has two stages. First, I expose a mistake in Husserl’s account of non-intuitive acts from his 1901 Logical Investigations. I demonstrate that Husserl employs the term “signitive” too broadly, as he concludes that all non-intuitive acts are signitive. He states that not only meaning acts, but also the contiguity intentions of perception are signitive acts. Second, I show how Husserl, in his 1913/14 Revisions to the Sixth (...) Logical Investigation, amends his 1901 theory of non-intuitive acts, which he now calls “empty” intentions. He there accurately distinguishes empty meaning acts from the empty intentions of perception. In the conclusion, I reveal how Husserl’s alterations to his theory of non-intuitive intentions can inform our understanding of a larger shift in his philosophy. (shrink)

Wilfrid Sellars claims that a scientific account of human beings will find it necessary to postulate a new type of basic particular, which he calls sensa. It is not entirely clear what are the reasons for which Sellars makes this claim. Sellars makes this claim. This thesis seeks to answer this question, and subsequently to evaluate what it finds to be Sellars' argument for sensa. Three possible arguments are distinguished. The argument from the homogeneity of colours ls taken to be (...) Sellars' principal argument. A key premise this argument ls that colours, because of their ultimate homogeneity, cannot be reduced to complexes of scientific properties and relations. This premise involves a principle of reducibility which close scrutiny reveals to be more problematic than it initially appears. The conclusion ls that the argument for sensa fails because it relies on an unjustified application of the principle. (shrink)

An important objection to signaling approaches to representation is that, if signaling behavior is driven by the maximization of usefulness, then signals will typically carry much more information about agent-dependent usefulness than about objective features of the world. This sort of considerations are sometimes taken to provide support for an anti-realist stance on representation itself. The author examines the game-theoretic version of this skeptical line of argument developed by Donald Hoffman and his colleagues. It is shown that their argument only (...) works under an extremely impoverished picture of the informational connections that hold between agent and world. In particular, it only works for cue-driven agents, in Kim Sterelny’s sense. In cases in which the agents’ understanding of what is useful results from combining pieces of information that reach them in different ways, and that complement one another, maximizing usefulness involves construing first a picture of agent-independent, objective matters of fact.

This paper reveals errors within Norwich et al.’s Entropy Theory of Perception, errors that have broad implications for our understanding of perception. What Norwich and coauthors dubbed their “informational theory of neural coding” is based on cybernetics, that is, control and communication in man and machine. The Entropy Theory uses information theory to interpret human performance in absolute judgments. There, the continuum of the intensity of a sensory stimulus is cut into categories and the subject is shown exemplar (...) stimuli of each category. The subject must then identify individual exemplars by category. The identifications are recorded in the Garner-Hake version of the Shannon “confusion matrix”. The matrix yields “H”, the entropy (degree of uncertainty) about what stimulus was presented. Hypothetically, uncertainty drops as a stimulus lengthens, i.e. a plot of H vs. stimulus duration should fall monotonically. Such “adaptation” is known for both sensation and firing rate. Hence, because “the physiological adaptation curve has the same general shape as the psychophysical adaptation curve”, Norwich et al. assumed that both have the same time course; sensation and firing rate were thus both declared proportional to H. However, a closer look reveals insurmountable contradictions. First, the peripheral neuron hypothetically cannot fire in response to a stimulus of a given intensity until after somehow computing H from its responses to stimuli of various intensities. Thus no sensation occurs until firing rate adapts, i.e. attains its spontaneous rate. But hypothetically, once adaptation is complete, certainty is reached and perception ends. Altogether, then, perception cannot occur until perception is over. Secondly, sensations, firing rates, and H’s are empirically not synchronous, contrary to assumption. In sum, the core concept of the cybernetics-based Entropy Theory of Perception, that is, that uncertainty reduction is the basis for perception, is irrational. (shrink)

There is a long‐standing project in psychology the goal of which is to explain our ability to perceive speech. The project is motivated by evidence that seems to indicate that the cognitive processing to which speech sounds are subjected is somehow different from the normal processing employed in hearing. The Motor Theory of speech perception was proposed in the 1960s as an attempt to explain this specialness. The first part of this essay is concerned with the Motor Theory's explanandum. (...) It shows that it is rather hard to give a precise account of what the Motor Theory is a theory of. The second part of the essay identifies problems with the theory's explanans: There are difficulties in finding a plausible account of what the content of the Motor Theory is supposed to be.

We resist Schilbach et al.’s characterization of the “social perception” approach to social cognition as a “spectator theory” of other minds. We show how the social perception view acknowledges the crucial role interaction plays in enabling social understanding. We also highlight a dilemma Schilbach et al. face in attempting to distinguish their second person approach from the social perception view.

The theory-ladenness of perception argument is not an argument at all. It is two clusters of arguments. The first cluster is empirical. These arguments typically begin with a discussion of one or more of the following psychological phenomena: (a) the conceptual penetrability of the visual system, (b) voluntary perceptual reversal of ambiguous figures, (c) adaptation to distorting lenses, or (d) expectation effects. From this evidence, proponents of theory-ladenness typically conclude that perception is in some sense "laden" with theory. (...) The second cluster attempts to extract deep epistemological lessons from this putative fact. Some philosophers conclude that science is not (in any traditional sense) a rational activity, while others conclude that we must radically reconceptualize what scientific rationality involves. Once we understand the structure of these arguments, much conventional wisdom about the significance of the psychological data turns out to be false. (shrink)

In this essay, our goal is to discover science in Martin Heidegger's Introduction to Metaphysics, lecture notes for his 1935 summer semester course, because, after all, his subject is metaphysica generalis, or ontology, and this could be construed as a theory of the human brain. Here, by means of verbatim quotes from his text, we attempt to show that indeed these lectures can be viewed as suggestion for an objective scientific theory of human perception, the human capacity for deciphering (...) phenomena, ie. hermeneutics in its broadest sense. His added notes from the 1953 edition, all of which are comments, not corrections, imply that he never abandoned these thoughts on metaphysics, despite all of his utterances about a need to overcome it, and their popular interpretations to that effect. In his presentation, he further develops the colorful and intuitive style, an hermeneutic language, that he had created in his earlier work Being and Time. Of human existence he speaks in such expressions as being-there -- ``Dasein" -- and being-in-the-world, the latter term no longer explicit in the 1935 lectures. The lectures can be read as a pre-scientific analysis of how man, being-there, perceives his environment, artfully managing to deal with the manifold challenges posed by the phenomenal structures of the universe. Man attentively recognizes and deciphers their pre-linguistic contents and, while trying to make sense of it all, puts into words his awareness. There are numerous passages in Heidegger's work where he in fairly concrete terms provides us with hints for a perceptive science that, as it turns out and is demonstrated below in this essay, can be explained in terms of recent advances in neuroscience. It would be implausible, even unthinkable, unimaginable, for there not to be found essential agreement between on one hand his philosophical insights gained by hermeneutics of Dasein, into how our brain functions to let us know what's happening & on the other hand, scientific discoveries obtained through anatomy, EEG, fMRI, TMS, electrode implants, etc, of brain structures & functions employed in perception of the momentary scene. A nexus between science and philosophy is provided in Heidegger's definitive treatment of the Logos, here interpreted as a structural version of Platonic forms (Burchard, 2014). This allows for neurolinguistic brain functions to serve as meta-context for Heidegger's being-in-the-world. The logical functions of Dasein's anatomical brain are performed by the logos machine, formerly the human soul, using top-down processing based on a global context, the noumenal cosmos which humans maintain internally. Heidegger's 1942/43 winter semester lectures Parmenides extend in unbroken fashion his 1935 work, proving that he never abandoned, as is widely claimed, his metaphysical avenue of thought. (shrink)

The direct social perception thesis claims that we can directly perceive some mental states of other people. The direct perception of mental states has been formulated phenomenologically and psychologically, and typically restricted to the mental state types of intentions and emotions. I will compare DSP to another account of mindreading: dual process accounts that posit a fast, automatic “Type 1” form of mindreading and a slow, effortful “Type 2” form. I will here analyze whether dual process accounts’ Type (...) 1 mindreading serves as a rival to DSP or whether some Type 1 mindreading can be perceptual. I will focus on Apperly and Butterfill’s dual process account of mindreading epistemic states such as perception, knowledge, and belief. This account posits a minimal form of Type 1 mindreading of belief-like states called registrations. I will argue that general dual process theories fit well with a modular view of perception that is considered a kind of Type 1 process. I will show that this modular view of perception challenges and has significant advantages over DSP’s phenomenological and psychological theses. Finally, I will argue that if such a modular view of perception is accepted, there is significant reason for thinking Type 1 mindreading of belief-like states is perceptual in nature. This would mean extending the scope of DSP to at least one type of epistemic state. (shrink)

I develop and defend a sense-datum theory of perception. My theory follows the spirit of classic sense-datum theories: I argue that what it is to have a perceptual experience is to be acquainted with some sense-data, where sense-data are private particulars that have all the properties they appear to have, that are common to both perception and hallucination, that constitute the phenomenal characters of perceptual experiences, and that may be aptly described as pictures in-side one’s head. But (...) my theory also diverges from conventional sense-datum theories in some key respects: on my view, (1) sense-data are first-person presentations of neural states, (2) the sensational qualities of sense-data differ in kind from the sensible qualities of external objects, and (3) sense-data are the vehicles in virtue of which we perceive, rather than the objects that we perceive. I argue that this package of claims is appropriately labeled ‘sense-datum theory’, and that the resultant view ought to be a live contender in contemporary philosophy of perception. (shrink)

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose (...) work was also very influential in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.

We briefly present Jocelyn Benoist’s (2011) Wittgensteinian contextualist approach to perception as we understand it and make some comments.

Conspectus of part of John R. Smythies' Analysis of Perception (1956). It presents a summary of his ideas on phenomenal space – the space of one’s imagination, dreams, psychedelic experiences, somatic sensations, visions, hynagogia, etc. – and its relation to physical space.

Como tantas vezes na filosofia, o título não só estabelece a linha de batalha, mas expõe os preconceitos e erros do autor, pois se podemos ou não entender o jogo de linguagem 'Ver as coisas como elas são' e se é possível ter uma "teoria filosófica" de percepção" (que é Pode ser sobre como a linguagem da percepção funciona), ao contrário de uma científica, que é uma teoria sobre como o cérebro funciona, são exatamente os problemas.

Estos son de especial interés como (como Wittgenstein) que no lee de las notas, por lo que cada uno es único y no una réplica de un papel, y es un excelente orador extemporáneo que en su mayoría utiliza un lenguaje sin pretensiones (ambos tan diferentes de la mayoría de los demás). Las conferencias recientes dadas en las Universidades Europeas son magníficas, pero no te pierdas las antiguas como la conferencia de la BBC "Una realidad cambiante, la ciencia del comportamiento humano", que da un excelente relato de por qué la causalidad legítima y repetitiva del rápido cerebro sistema automático, no linguístico 1 (S1) es fundamentalmente diferente y no destacable de la misma manera que la complejidad ilimitada de razones que caracterizan el lento sistema deliberativo, consciente de la lengua 2 (S2), que genera una explosión combinatoria no generalmente representable de una manera útil por las leyes científicas. El sistema dual (S1, S2) método de describir el pensamiento utilizado en esta revisión, común a la investigación de razonamiento desde hace unos 20 años, es mío y no de Searle. Dado que recientemente he escrito un artículo de 75p analizando el trabajo de Searle en comparación con el de Wittgenstein (La estructura lógica de la filosofía, la psicología, la mente y el lenguaje como revelado por Ludwig Wittgenstein y John Searle) no lo repetiré y lo repetiré concentrarse en este libro solamente.

The question of what we immediately perceive from the first-person point of view has been an issue of philosophizing since the beginning of Western philosophy. However, many philosophers have not considered all theoretical and practical consequences concerning identity and causation in perceptual experience between a perceiver and the external world. Despite their meritorious studies, philosophers have failed to completely understand how the causal series of events affects what we immediately experience. Using facts relating to perceivers, logical reasoning, introspection, and philosophical (...) theories, the aim of this research is to show that objects of sense have been contradictorily and confusedly associated with several objects in philosophy of perception. The research problem is that of whether the entity external to a perceiver is identical to the immediate object of perceptual experience. The research starts from the basic beliefs that things appear in experience and that there is causality in perceptual experience. After presenting philosophical theories of perception, the concept ‘sense-datum’, a characterization of ‘perception’, and basic arguments for perceiving the inner private sense-datum, the study examines Bertrand Russell’s and G. E Moore’s arguments for a claim that we always perceive mind-internal sense-data. This claim is problematic if ‘sense-datum’ is considered as being under the category of substance. Nonetheless, evidence for a claim in direct realism and eliminative materialism that the immediate object of perception is an external entity leads to circularity and identity problems. Finally, by means of a demonstration based on understanding and facts in perceivers and perceptual phenomena, the research concludes that the external entity is not identical to the immediate object of perceptual experience. Perceptual experience does not directly reach the external world, and the objects of sense are not independent of the perceiver. (shrink)

Maria Gołaszewska (1926–2015) was a Polish philosopher associated throughout her life with Poland’s oldest academic institution, the Jagiellonian University in Cracow. She was a student of the phenomenologist Roman Ingarden, himself a student of Edmund Husserl. During the post-war and communist years in Poland, Gołaszewska conducted research focusing on issues related to art and aesthetics. She created her own conception of empirically and anthropologically oriented aesthetics, which I believe is a prime example of a theory that accounts for the perspective (...) of gender, and which in this sense should be acknowledged as having anticipated the main postulates of contemporary feminist philosophy. In the article I present Gołaszewska’s philosophy as a cognitively valuable response to the search of feminist aesthetics for a suitable description of women’s experiences related to art and aesthetic perception. In accordance with this aim, I discuss Gołaszewska’s theory of the aesthetic situation, a framework within which she proposed solutions similar to feminist standpoint theories. These theories were developed chiefly on the basis of the feminist philosophy and feminist epistemology (Elizabeth Anderson, Donna Haraway, Sandra Harding, Elizabeth Potter). In recent years they have also found creative applications in feminist aesthetics (Anne Eaton). (shrink)

Review of Searl's book Seeing Things as They are.

The present paper is concerned with Helmholtz’s theory of measurement. It will be argued that an adequate understanding of this theory depends on how Helmholtz’s application of the concepts of perception and coincidence is interpreted. In contrast both to conventionalist and Kantian readings of Helmholtz’s theory, a more realistic interpretation will be suggested.

How does the philosophical debate between naive realism and intentionalism relate to the psychological debate between ecological theories and constructivist theories? The participants in each debate take themselves to be doing something distinctive, but I show that characterizing the distinction is difficult: the theories in both debates use inference to the best explanation to draw contingent conclusions about the constitutive nature of perception. I argue that both debates concern the metaphysics of perception, and that philosophers (...) of perception are wrong to think that constructivist and ecological theories are engaged in a distinct and non-metaphysical task.

Change is omnipotent, differentialism is omnipresent. Philosophy rigorously interrogates perceived realities, employing a disciplined methodology to address the fundamental exis- tential questions: the essence of existence, its underlying reasons, and the processes that sustain it. This exploratory approach, a natural human tendency evident across life stages, has profoundly influenced the development of theories across various disciplines, reshaping our worldview and altering historical narratives. Yet, this iterative process of thought and cognition often culminates in deeply entrenched beliefs, accepted without critical (...) scrutiny and justified by ‘rational methodologies.’ Recognizing these biases, philosophers have histor- ically devised strategies to confront and mitigate such preconceptions. Despite these efforts, the discourse often remains anchored in a self-referential historical context, necessitating a paradigm shift to accommodate the accelerating pace of change. -/- This thesis employs descriptive and normative methods to scrutinize the rational processes of perception, cognition, and action. I introduce the differential framework, a robust construct that encapsulates this cyclical process of sense-making. This framework uses pre-existing understandings as a basis to articulate new perspectives on the evolving world. The dis- course is particularly relevant to the philosophy of mind, information, and ethics, especially as we confront the profound implications of AI and transhumanism. Rapid advancements in these fields challenge our traditional methods and demand adaptive responses, urging a reevaluation of our ethical frameworks and cognitive models in light of emerging realities. This work seeks to bridge the gap between classical philosophical inquiry and the urgent questions posed by the next steps in human evolution, emphasizing the necessity of inte- grating technology with humanity in a way that respects and enhances fundamental human values.

This article is a comparative study between predictive processing (PP, or predictive coding) and cognitive dissonance (CD) theory. The theory of CD, one of the most influential and extensively studied theories in social psychology, is shown to be highly compatible with recent developments in PP. This is particularly evident in the notion that both theories deal with strategies to reduce perceived error signals. However, reasons exist to update the theory of CD to one of “predictive dissonance.” First, the (...) hierarchical PP framework can be helpful in understanding varying nested levels of CD. If dissonance arises from a cascade of downstream and lateral predictions and consequent prediction errors, dissonance can exist at a multitude of scales, all the way up from sensory perception to higher order cognitions. This helps understand the previously problematic dichotomy between “dissonant cognitive relations” and “dissonant psychological states,” which are part of the same perception-action process while still hierarchically distinct. Second, since PP is action-oriented, it can be read to support recent action-based models of CD. Third, PP can potentially help us understand the recently speculated evolutionary origins of CD. Here, the argument is that responses to CD can instill meta-learning which serves to prevent the overfitting of generative models to ephemeral local conditions. This can increase action-oriented ecological rationality and enhanced capabilities to interact with a rich landscape of affordances. The downside is that in today’s world where social institutions such as science a priori separate noise from signal, some reactions to predictive dissonance might propagate ecologically unsound (underfitted, confirmation-biased) mental models such as climate denialism.

In this paper I will try to outline a Metaphysics of Perception that takes for granted one of the central thesis of the metaphysical doctrine called Indirect Realism. Firstly, I will introduce the central thesis of Indirect Realism and then a special version of the Causal Theory of Perception that modifies in some fundamental respect one of the most influential version of Causal Theory of Perception designed by William Child.

The paper rejects the claim that phenomena such as change and inattentional blindness show that perceptual representations are inaccurate or that a radical overhaul of our traditional picture of perception is required. The paper rejects in particular the sensorimotor theory of perception, which denies that there are any perceptual representations. It further argues that the degree of resolution of perceptual experience relevant to assessing its accuracy is determined by our use of it in standard conditions, and that the (...) integration of behavior with perceptual representation shows that it is by and large as accurate as its degree of resolution requires.

Emotional states of consciousness, or what are typically called emotional feelings, are traditionally viewed as being innately programed in subcortical areas of the brain, and are often treated as different from cognitive states of consciousness, such as those related to the perception of external stimuli. We argue that conscious experiences, regardless of their content, arise from one system in the brain. On this view, what differs in emotional and non-emotional states is the kind of inputs that are processed by (...) a general cortical network of cognition, a network essential for conscious experiences. Although subcortical circuits are not directly responsible for conscious feelings, they provide non-conscious inputs that coalesce with other kinds of neural signals in the cognitive assembly of conscious emotional experiences. In building the case for this proposal, we defend a modified version of what is known as the higher-order theory of consciousness. (shrink)

Evaluative theories of emotions purport to shed light on the nature of emotions by appealing to values. Three kinds of evaluative theories of emotions dominate the recent literature: the judgment theory equates emotions with value judgments; the perceptual theory equates emotions with perceptions of values, and the attitudinal theory equates emotions with evaluative attitudes. This paper defends a fourth kind of evaluative theory of emotions, mostly neglected so far: the reactive theory. Reactive theories claim that emotions are (...) attitudes which arise in reaction to perceptions of value. (shrink)

Several philosophers think there are important analogies between emotions and perceptual states. Furthermore, considerations about the rational assessibility of emotions have led philosophers—in some cases, the very same philosophers—to think that the content of emotions must be propositional content. If one finds it plausible that perceptual states have propositional contents, then there is no obvious tension between these views. However, this view of perception has recently been attacked by philosophers who hold that the content of perception is object-like. (...) I shall argue for a view about the content of emotions and perceptual states which will enable us to hold both that emotional content is analogous to perceptual content and that both emotions and perceptual states can have propositional contents. This will involve arguing for a pluralist view of perceptual content, on which perceptual states can have both contents which are proposition-like and contents which are object-like. I shall also address two significant objections to the claim that emotions can have proposition-like contents. Meeting one of these objections will involve taking on a further commitment: the pluralist account of perceptual content will have to be one on which the contents of perception can be non-conceptual.

The present article is an attempt to give - in the frame of the theory of the organism - environment system - a new interpretation to the role of efferent influences on receptor activity and to the functions of senses in the formation of knowledge. It is argued, on the basis of experimental evidence and theoretical considerations, that the senses are not transmitters of environmental information, but they create a direct connection between the organism and the environment, which makes the (...) development of a dynamic living system, the organism - environment system, possible. In this connection process the efferent influences on receptor activity are of particular significance, because with their help the receptors may be adjusted in relation to the parts of the environment which are most important in the achievement of behavioral results. Perception is the process of joining of new parts of the environment to the organism - environment system ; thus, the formation of knowledge by perception is based on reorganization of the organism - environment system, and not on transmission of information from the environment. With the help of the efferent influences on receptors each organism creates its own peculiar world which is simultaneously subjective and objective. The present considerations have far reaching influences as well on experimental work in neurophysiology and psychology of perception as on philosophical considerations of knowledge formation.

This paper addresses the question of what the attitude of hope consists in. We argue that shortcomings in recent theories of hope have methodological roots in that they proceed with little regard for the rich body of literature on the emotions. Taking insights from work in the philosophy of emotions, we argue that hope involves a kind of normative perception. We then develop a strategy for determining the content of this perception, arguing that hope is a (...) class='Hi'>perception of practical reasons. Our proposal stands in contrast with familiar views on which hope is fundamentally about the good. We conclude by considering the increasingly popular idea that some hopes are non-intentional and thus, by implication, non-perceptual. We reply by arguing that our perceptual theory plausibly generalizes to these instances of hope. (shrink)
