The paper addresses the issue of theory-ladenness of observation/experimentation. Motivated by a naturalistic reading of Thomas Kuhn's insights into the same topic, I draw on cognitive neuroscience (predictive coding under Free Energy Principle) to scrutinise theory-ladenness. I equate theory-ladenness with the cognitive penetrability of perceptual inferences and argue that strong theory-ladenness prevails only under uncertain circumstances. This understanding of theory-ladenness is in line with Thomas Kuhn's view on the same subject as well as a cognitive version of (...) modest realism rather than downright antirealism. (shrink)

A study of the major philosophical theories of knowledge from Plato to Husserl intending to show the pivotal role of Descartes and the influence of his unjustified assumption of mental reality for ideas. On the basis of this study, the book suggests the need to return to the pre-Cartesian cognitive realism of the Greeks and Medievals.

In a recent article, Giulia Felappi has leveled a challenge for those who believe that propositional attitudes involve relations between subjects and propositions: they must say more about what it is for a given proposition to figure as the content of one’s attitude. This note argues that Felappi’s challenge has already been met by proponents of act-theoretic conceptions of propositions.

Most of the work in agent-based social simulation has assumed highly simplified agent models, with little attention being paid to the details of individual cognition. Here, in an effort to counteract that trend, we substitute a realistic cognitive agent model (CLARION) for the simpler models previously used in an organizational design task. On that basis, an exploration is made of the interaction between the cognitive parameters that govern individual agents, the placement of agents in different organizational structures, and (...) the performance of the organization. It is suggested that the two disciplines, cognitive modeling and social simulation, which have so far been pursued in relative isolation from each other, can be profitably integrated. (shrink)

Humans and other animals have an evolved ability to detect discrete magnitudes in their environment. Does this observation support evolutionary debunking arguments against mathematical realism, as has been recently argued by Clarke-Doane, or does it bolster mathematical realism, as authors such as Joyce and Sinnott-Armstrong have assumed? To find out, we need to pay closer attention to the features of evolved numerical cognition. I provide a detailed examination of the functional properties of evolved numerical cognition, and propose that (...) they prima facie favor a realist account of numbers. (shrink)

There is a long-standing discussion concerning the nature of moral discourse. Multiple views range from realism—according to which moral discourse is closer to scientific discourse than to fictional discourse—to anti-realism—according to which moral discourse is rather closer to fictional discourse. In this paper, I want to motivate a novel anti-realist account. On this view, there are no moral properties or truths, neither mind-independent nor mind-dependent ones (i.e., anti-realism). However, moral cognition results from the use of higher order (...) cognitive abilities with enough resources to grant moral discourse with all the features of a realist talk (i.e., cognitive quasi-realism). I defend this view based on empirical evidence on human moral development and by showing that the resulting account can meet the demands of robust moral realism. The paper concludes by placing the proposed view within the metaethical landscape by comparing it against other forms of anti-realism, most significantly against expressivism. (shrink)

There are two distinct approaches to Bayesian modelling in cognitive science. Black-box approaches use Bayesian theory to model the relationship between the inputs and outputs of a cognitive system without reference to the mediating causal processes; while mechanistic approaches make claims about the neural mechanisms which generate the outputs from the inputs. This paper concerns the relationship between these two approaches. We argue that the dominant trend in the philosophical literature, which characterizes the relationship between black-box and mechanistic (...) approaches to Bayesian cognitive science in terms of the dichotomy between instrumentalism and realism, is misguided. We propose that the two distinctions are orthogonal: black-box and mechanistic approaches to Bayesian modelling can each be given either an instrumentalist or a realist interpretation. We argue that the current tendency to conflate black-box approaches with instrumentalism and mechanistic approaches with realism stems from unwarranted assumptions about the nature of scientific explanation, the ontological commitments of scientific theories, and the role of abstraction and idealization in scientific models. We challenge each of these assumptions to reframe the debates over Bayesian modelling in cognitive science. (shrink)

The debate about scientific realism is concerned with the relation between our scientific theories and the world. Scientific realists argue that our best theories or components of those theories correspond to the world. Anti-realists deny such a correspondence. Traditionally, this central issue in the philosophy of science has been approached by focusing on the theories themselves (e.g., by looking at theory change or the underlying experimental context). I propose a relatively unexplored way to approach this old debate. In addition (...) to focusing on the theory, we should focus on the theorizer. More precisely, in order to determine on which component of a theory we should hinge a realist commitment, we should analyze the cognitive processes underlying scientific theorizing. In this paper I do just that. Drawing from recent developments in the cognitive sciences and evolutionary epistemology, I formulate some tentative conclusions. The aim of this paper is not so much to defend a particular position in the debate on scientific realism but to showcase the value of taking a cognitive perspective in the debate. (shrink)

Debate on the nature of representation in cognitive systems tends to oscillate between robustly realist views and various anti‐realist options. I defend an alternative view, deflationary realism, which sees cognitive representation as an offshoot of the extended application to cognitive systems of an explanatory model whose primary domain is public representation use. This extended application, justified by a common explanatory target, embodies idealisations, partial mismatches between model and reality. By seeing representation as part of an idealised (...) model, deflationary realism avoids the problems with robust realist views, while keeping allegiance to realism. (shrink)

Perceptual experience has representational content. My argument for this claim is an inference to the best explanation. The explanandum is cognitive penetration. In cognitive penetration, perceptual experiences are either causally influenced, or else are partially constituted, by mental states that are representational, including: mental imagery, beliefs, concepts and memories. If perceptual experiences have representational content, then there is a background condition for cognitive penetration that renders the phenomenon prima facie intelligible. Naïve realist or purely relational accounts of (...) perception leave cognitive penetration less well-explained, even when formulated with so-called ‘standpoints’ or ‘third relata.’. (shrink)

What can we infer from numerical cognition about mathematical realism? In this paper, I will consider one aspect of numerical cognition that has received little attention in the literature: the remarkable similarities of numerical cognitive capacities across many animal species. This Invariantism in Numerical Cognition (INC) indicates that mathematics and morality are disanalogous in an important respect: proto-moral beliefs differ substantially between animal species, whereas proto-mathematical beliefs (at least in the animals studied) seem to show more similarities. This (...) makes moral beliefs more susceptible to a contingency challenge from evolution compared to mathematical beliefs, and indicates that mathematical beliefs might be less vulnerable to evolutionary debunking arguments. I will then examine to what extent INC can be used to flesh out a positive case for mathematical realism. Finally, I will review two forms of mathematical realism that are promising in the light of the evolutionary evidence about numerical cognition, ante rem structuralism and Millean empiricism.

The author outlines one form of analytical legal realism as the junction of three main theses. According to its first main thesis, interpretive sentences in legal discourse are ascriptive sentences with no cognitive function. According to the second thesis, the law is the set of norms in force, i.e. the norms actually applied in the past and predictably applied in the future by law-applying agencies. The third thesis is that legal science as a cognitive activity must not (...) be confused with legal scholarship. Although legal scholars do engage in cognitive activities, their work mainly consists in non-cognitive activities such as interpretation and legal construction. | An earlier version of this statement was published in Revus 19 in Italian, French, and Croatian.

In this paper, I show how Thomas Aquinas's account of sensory cognition is undergirded by a strong commitment to direct realism. According to the specific form of direct realism I articulate and defend here, which I claim emerges from a proper study of Aquinas's account of sensory cognition, it is only by having sense experiences that possess definitive content--content that is isomorphic or formally identical with the sensible features of mind-independent reality--that we can be credited with occupying world-intending (...) sensory states, in which we see, hear, taste, touch, and smell objective aspects or features of the world itself. Thus, it is by virtue of possessing the requisite content that the veridical sensations or perceptions we enjoy and possess bear directly on the world, and thereby unite us to the world. In defending this claim, I exposit what I take to be the most important features of Aquinas's account of sensory cognition: most notably, the operation of the external senses, and secondarily, the role of the common sense and phantasms. Interpreting Aquinas in the right light allows us better to understand and appreciate his account of sensory cognition as well as the nature and benefits of direct realism itself. (shrink)

In this book, the author develops a new form of structural realism and deals with the problem of representation. The work combines two distinguished developments of the Semantic View of Theories, namely Structural Realism, a flourishing theory from contemporary philosophy of science, and Ronald Giere and colleagues’ Cognitive Models of Science approach. Readers will see how replacing the model-theoretic structures that are at issue in SR with connectionist networks and activations patterns helps us to deal with the (...) problem of representation. The author suggests that cognitive structures are not only the precise formal tools for regimenting the structure of scientific theories but also the tools that the biological brain uses to capture the essential features of its environment. Therefore, replacing model-theoretic structures with cognitive structures allows us to account for the theories-reality relationship on the basis of the most reliable theories of neurology. This is how a new form of SR, called Cognitive Structural Realism is introduced through this book, which articulates and defends CSR, and shows how two diverging branches of SVT can be reconciled. This ground-breaking work will particularly appeal to people who work in the philosophy of science, philosophy of mind and cognitive sciences. (shrink)

Embodied and extended cognition is a relatively new paradigm within cognitive science that challenges the basic tenet of classical cognitive science, viz. cognition consists in building and manipulating internal representations. Some of the pioneers of embodied cognitive science have claimed that this new way of conceptualizing cognition puts pressure on epistemological and ontological realism. In this paper I will argue that such anti-realist conclusions do not follow from the basic assumptions of radical embodied cognitive science. (...) Furthermore I will show that one can develop a form of realism that reflects rather than just accommodates the core principles of non-representationalist embodied cognitive science. (shrink)

Changing and often class-dependent non-stationarities of signals are a big challenge in the transfer of common findings in cognitive workload estimation using Electroencephalography (EEG) from laboratory experiments to realistic scenarios or other experiments. Additionally, it often remains an open question whether actual cognitive workload reflected by brain signals was the main contribution to the estimation or discriminative and class-dependent muscle and eye activity, which can be secondary effects of changing workload levels. Within this study, we investigated a novel (...) approach to spatial filtering based on beamforming adapted to changing settings. We compare it to no spatial filtering and Common Spatial Patterns (CSP). We used a realistic maneuvering task, as well as an auditoryn-backsecondary task on a tugboat simulator as two different conditions to induce workload changes on professional tugboat captains. Apart from the typical within condition classification, we investigated the ability of the different classification methods to transfer between then-backcondition and the maneuvering task. The results show a clear advantage of the proposed approach over the others in the challenging transfer setting. While no filtering leads to lowest within-condition normalized classification loss on average in two scenarios (22 and 10%), our approach using adaptive beamforming (30 and 18%) performs comparably to CSP (33 and 15%). Importantly, in the transfer from one to another setting, no filtering and CSP lead to performance around chance level (45 to 53%), while our approach in contrast is the only one capable of classifying in all other scenarios (34 and 35%) with a significant difference from chance level. The changing signal composition over the scenarios leads to a need to adapt the spatial filtering in order to be transferable. With our approach, the transfer is successful due to filtering being optimized for the extraction of neural components and additional investigation of their scalp patterns revealed mainly neural origin. Interesting findings are that rather the patterns slightly change between conditions. We conclude that the approaches with low normalized loss depend on eye and muscle activity which is successful for classification within conditions, but fail in the classifier transfer since eye and muscle contributions are highly condition-specific.

Our cognitive capabilities force us into a description of the world by levels. But theories on different levels result in descriptions that differ qualitatively. Therefore, the resulting incommensurability requires ontological bridges between such theories. These are obtained uniquely when the equations of the reduced theory are compared with a suitable limit of the equations of the reducing theory. Four case studies from theoretical physics and astronomy support this claim, two for theories of composites and two for non-composites (field theories). (...) These results a coherent view of a single real world despite its ontological pluralism. The cumulativity of scientific knowledge is thus ensured and realism is supported. (shrink)

Chemero provides a modern re-interpretation of Gibson’s ecological psychology and his affordance concept that is more coherent than the original and in line with antirepresentationalist, dynamical theories in embodied cognitive science. He argues for a radical embodied cognitive science, in which ecological and enactive approaches join forces against the more watered-down, mainstream embodied cognitive science that still maintains traditional commitments to representationalism and computationalism. He also defends a special version of realism, entity realism, which many (...) constructivists might not find entirely convincing, but which is nevertheless more or less compatible with enactive theories of embodied cognition.

Ruben Berrios Queen’s University Belfast Anti-realism and Aesthetic Cognition Abstract At the core of the debate between scientific realism and anti-realism is the question of the relation between scientific theory and the world. The realist possesses a mimetic conception of the relation between theory and reality. For the realist, scientific theories represent reality. The anti-realist, in contrast, seeks to understand the relations between theory and world in non-mimetic terms. We will examine Cartwright’s simulacrum account of explanation in (...) order to illuminate the anti-realist position. Science consists of phenomenological and theoretical laws. The former are concerned with appearances, or those phenomena that can be directly observed; the latter involve the unobservable reality that is alleged to underlie appearances, and are capable only of indirect confirmation. Phenomenological laws are said to be descriptive, whilst theoretical laws are understood as explanatory. Cartwright is concerned with the theoretical. She claims that the standard realist account of the explanatory efficacy of theoretical laws is faulty. The explanatory power of theoretical laws consists in their ability to provide an explanation of physical phenomena. According to Cartwright, the realist claims that laws explain phenomena by providing an abstract description of them, in terms of their micro-structural features, that is alleged to be true. On this view, explanatory power is entirely dependent on descriptive adequacy. As phenomenological laws describe appearances, so theoretical laws describe the fundamental reality that governs appearances. Cartwright rejects the preceding view and in its place proposes a simulacrum account of explanation. According to Cartwright, the explanatory power of theoretical laws is related not to descriptive adequacy, but rather to the construction of adequate models. To explain a phenomenon is to construct a model which best or most adequately accommodates the phenomenon to a theory. The model will consist of various posited objects that serve to explain the phenomena in terms that are consistent with a set of theoretical laws. Cartwright claims that theoretical laws are true of, or describe, the objects of the model. The objects of the model, however, are not descriptive of reality. They are simulacra. They have, that is, the form or appearance of things, without possessing their substance or proper qualities. In light of the foregoing account we can summarise the distinction between scientific realism and anti-realism as follows. The realist claims that theoretical laws literally represent real objects. The anti-realist claims that laws represent objects of a model that are simulacra of reality. Anti-realism has an aesthetic dimension. The movement from realism to anti-realism is also the movement from the mimetic conception of the scientist as holding a mirror to nature to the constructionist view of the scientist as engaging with nature through invention. There is a lot of the artist in the anti-realist’s view of the scientist. This is true for Cartwright as well as, for example, Van Fraassen in his doctrine of constructive empiricism. It would appear, then, that the philosophy of science has absorbed some concepts that are ordinarily housed in aesthetics. And it has done so profitably. The aim of this paper is to reverse the direction of disciplinary influence. Can art, in relation to its status as a cognitive enterprise, be illuminated by scientific anti-realism? I will argue that it can. In an unexpected reference to the Nicomachean Ethics, Cartwright draws a suggestive parallel between theoretical laws and general moral principles, on the one hand, and physical phenomena and everyday moral conduct, on the other hand. If we add to this the claim that a central component of art’s value is cognitive, then we have the basic materials with which to flesh out a broadly anti-realist view of art. In the production of art, artists can construct models that mediate between everyday ethical phenomena and general ethical tendencies. These models reveal the ways in which there are implicit consistencies or inconsistencies, conflicts or congruences and so forth, between the phenomena and the tendencies. On this basis art can contribute to the reflective understanding of ethical life. This constitutes to a large degree art’s status as a cognitive enterprise. To apprehend art cognitively as artist or critic is to engage in aesthetic cognition. (shrink)

The author shows that the conception of epistemological realism as a contemporary variant of epistemological realism continues the realism tradition and at the same time takes into account some constructivist ideas, giving them a new interpretation. Constructive realism can be a fruitful strategy in cognitive studies, as it gives a philosophical interpretation of the current popular approach in cognitive science: so called “4 E approach”: understanding cognition as embodied, enacted. embedded and extended. The problem (...) of Illusion and Reality is analyzed from the position of constructive realism. The relations between different surrounding worlds of different cognitive agents and the common real world is specially investigated in the context of the opposition between Realism and Relativism.

Let’s define epistemological direct realism as the view that we have noninferentially justified beliefs in at least some contingent propositions describing the external physical world. I add the adjective “external” here so as to leave open the question of whether sensations and other mental phenomena are themselves physical. I take it that an indirect realist can consistently maintain both that all knowledge of external physical reality must be inferred from knowledge of subjective sensations and also conclude that subjective sensations (...) are, for example, brain states. It’s a bit awkward, however, to use the cumbersome expression “external physical reality” and so for ease of exposition I shall often omit the adjective “external.” I shall say that a proposition describes the physical world only if its truth entails a proposition which attributes to some object those properties in virtue of which the thing is physical. So, for example, I might be able to know that the F exists, where the F is, in fact, a physical object. But if the proposition that the F exists does not entail that the F is physical, the proposition that the F exists is not, in this sense, a proposition describing the physical world. Berkeley, for example, sometimes posed as an epistemological direct realist when he claimed both that we can know unproblematically that certain ideas exist and that a physical object is nothing but a bundle of ideas. But when he was being careful he made clear that the ideas we know directly are never by themselves constitutive of a physical object—at best they are logical “parts” of objects. On his more sophisticated view, knowledge that a given physical object exists would always require inference—complex inference at that. Berkeley was no epistemological direct realist. (shrink)

Recent research on “causal cognition” in adults and infants shows that we can perceive singular causal relations not previously experienced. In particular, infants that are able to perceive causality seem to rely on innate beliefs and principles that allow a priori inference of a connection between cause and effect. Can causal cognition in infants justify the thesis of causal realism? On the one hand, it weakens the central pillar of the Humean arguments: the impossibility of a synthetic a priori (...) causal inference. On the other hand, if perception is the privileged way of justifying the reality of objects of the external world, that is valid in the case of causal relations as well. Moreover, the perception of causal relations, based on innate principles and beliefs, reflects the selective results of the interaction between the real constraints of the physical structure of the world and the evolution of the human mind.

Building on previous work, I continue the arguments for scientific realism in the presence of a natural level structure of science. That structure results from a cognitive antireductionism that calls for the retention of mature theories even though they have been "superseded". The level structure is based on "scientific truth" characterized by a theory's validity domain and the confirming empirical data. Reductionism (including fundamentalism) fails cognitively because of qualitative differences in the ontology and semantics of successive theories. This (...) cognitive failure exists in spite of the mathematical success of theory reduction. The claim for scientific realism is strongly based on theory coherence between theories on adjacent levels. Level coherence consists of mathematical relations between levels, as well as of reductive explanations. The latter refers to questions that can be posed (but not answered) on a superseded level, but which can be answered (explained) on the superseding level. In view of the pluralism generated by cognitive antireductionism, theory coherence is claimed to be so compelling that it provides strong epistemic justification for a pluralistic scientific realism.

What follows is a first step towards an ontology of conscious mental processes. We provide a theoretical foundation and characterization of conscious mental processes based on a realist theory of intentionality and using BFO as our top-level ontology. We distinguish three components of intentional mental process: character, directedness, and objective referent, and describe several features of the process character and directedness significant to defining and classifying mental processes. We arrive at the definition of representational mental process as a process that (...) is the bringing into being, sustaining, modifying, or terminating of a mental representation. We conclude by outlining some benefits and applications of this approach. (shrink)

Metaphysical realism, though not under that name, runs throughout the entire Western tradition at least since Parmenides. His basic ontological claim, that is, that what is is and cannot not be, hence cannot change, influentially creates a central philosophical task. Cognitive foundationalism, whose exemplar is Descartes, is a cognitive strategy intended to respond to metaphysical realism. Plato rejects any form of a representational approach to knowledge in rejecting the backward causal inference from ideas in the mind (...) to the world. The Cartesian strategy is based on a justified inference from the idea in the mind to the world, which reverses the Platonic criticism. Criticism of the Cartesian inference from the idea in the mind to the world supports Plato’s rejection of representationalism in all its forms. (shrink)

Pragmatism and critical realism are different vocabularies for talking about the cognitive value of religion and science. Each can be, and has been, used to make the case for cognitive parity between religious and scientific discourse. Critical realism presupposes a particular form of cognitive psychology that entails general skepticism about the external world and forecloses scientific inquiry in the name of a preconceived idea of what the nature of human cognition must be. Thus, of the (...) two, pragmatism is the better vocabulary for fostering mutual understanding between religion and science. (shrink)

Kant’s Critique of Pure Reason contains an original and powerful semantics of singular cognitive reference which has important implications for epistemology and for philosophy of science. Here I argue that Kant’s semantics directly and strongly supports Newton’s Rule 4 of Philosophy in ways which support Newton’s realism about gravitational force. I begin with Newton’s Rule 4 of Philosophy and its role in Newton’s justification of realism about gravitational force (§2). Next I briefly summarize Kant’s semantics of singular (...) cognitive reference (§3), and then show that it is embedded in and strongly supports Newton’s Rule 4, and that it rules out not only Cartesian physics (per Harper) but also Cartesian, infallibilist presumptions about empirical justification generally (§4). This result exposes a key fallacy in Bas van Fraassen’s original argument for his anti-realist Constructive Empiricism (§5). (shrink)

Empirical investigations use empirical methods, data and evidence. This banal observation appears to favour empiricism, especially in philosophy of science, though no rationalist ever denied their importance. Natural sciences often provide what appear to be, and are taken by scientists as, realist, causal explanations of natural phenomena. Empiricism has never been congenial to scientific realism. Bas van Fraassen’s ‘Constructive Empiricism’ purports that realist interpretations of any scientific theory in principle always transcend whatever can be justified by that theory’s empirical (...) adequacy, and that ‘explanations’ are merely pragmatic, insofar as they are context-specific to the presuppositions of whomever poses the question an explanation is to answer. Here I argue that ‘Constructive Empiricism’ rests upon a series of flawed presumptions about natural science and about epistemology. To do so I draw upon two main resources. One resource is the constraints upon specifically cognitive reference to particulars, first identified by Kant (and later by Evans). The second is William Harper’s (2011) brilliant re-analysis and defence of Newton’s Principia, which shows that, and how, Newton justified his realism about gravitational force. One surprise is that Kant’s semantics of singular cognitive reference (examined in §3) directly and strongly supports Newton’s Rule 4 of scientific method (§4), which strongly supports his realism about gravitational force (summarised in §2). A further surprise is that Hegel first recognised that this semantics of singular cognitive reference directly and strongly supports Newton’s methodological Rule 4 of experimental philosophy in ways which support Newton’s realism about gravitational force, and about distance forces generally. The textual and exegetical issues these attributions require I examine elsewhere. Here I make these important findings available to philosophers and historians of science. (shrink)

This paper argues that neurolinguistics has the potential to yield insights that can feed back into corpus-based Cognitive Linguistics. It starts by discussing how far the cognitive realism of probabilistic statements derived from corpus data currently goes. Against this background, it argues that the cognitive realism of usage-based models could be further enhanced through deeper engagement with neurolinguistics, but also highlights a number of common misconceptions about what neurolinguistics can and cannot do for linguistic theorizing.

This article explores the limits of social constructionism and criticizes the `demiurgic conception of society' associated with it. It contemplates the possibility of sociological realism by investigating the intrinsic and objective properties of action, cognition and morality. The incorporation of intrinsic meanings and intentions in social actions, the objective information supporting cognitive processes and human sensitivity to pleasure and pain as well as the normative rejection of undue suffering, delineate the objective core of social facts, which can be (...) interpreted or influenced, but not arbitrarily or capriciously constructed or manipulated. This general argument is supported by various illustrations drawn from the semantics of social actions and classical puzzles of interpretative sociology such as the meaning of suicide or the morality of social sanctions.

Some naturalistic philosophers of mind subscribing to the predictive processing theory of mind have adopted a realist attitude towards the results of Bayesian cognitive science. In this paper, we argue that this realist attitude is unwarranted. The Bayesian research program in cognitive science does not possess special epistemic virtues over alternative approaches for explaining mental phenomena involving uncertainty. In particular, the Bayesian approach is not simpler, more unifying, or more rational than alternatives. It is also contentious that the (...) Bayesian approach is overall better supported by the empirical evidence. So, to develop philosophical theories of mind on the basis of a realist interpretation of results from Bayesian cognitive science is unwarranted. Naturalistic philosophers of mind should instead adopt an anti-realist attitude towards these results and remain agnostic as to whether Bayesian models are true. For continuing on with an exclusive focus and praise of Bayes within debates about the predictive processing theory will impede progress in philosophical understanding of scientific practice in computational cognitive science as well as of the architecture of the mind.

My concern in this paper is what, in Art and Illusion, Gombrich calls "the riddle of style". This is the problem of why people at different times and in different cultures have depicted objects in very different ways. An adequate solution to this problem will comprise an explanation of why depiction has a history. The problem seems intractable because of three common assumptions about the history of depiction that, while independently plausible, are inconsistent. First, we assume that this history is (...) a history of realism. Artists from a wide range of cultures and ages seem to have shared the common goal of capturing the visual appearances of the objects they depicted. Secondly, we assume that depictive styles differ from context to context in part because of features internal to the contexts in which they emerged. Finally, we are loathe to accept the claim that differences of style necessarily result from differences in technical capacity. However, these assumptions are in conflict. If artists throughout history sought to capture the appearances of the things they depicted and did not differ markedly in their technical capacities, then surely the pictures each produced should not depend on features internal to the contexts in which they emerged and should instead look more alike. -/- I argue that the history of style is not, in its entirety, a history of realism. Throughout history, pictures have been used to inform viewers about a wide variety of things other than their objects' appearances. Investigating the purposes for which pictures were used in particular historical and cultural contexts will help us to understand why certain styles were appropriate to those contexts. Nevertheless, it will not help us to understand why certain styles were appropriate to just one among a number of contexts in which pictures were used for a single purpose. To understand this, we need to know what cognitive environment was shared by the members of the relevant community. This will enable us to understand why, given the purpose for which pictures were used in that community, a certain style was more informative than another. In addition to cataloguing stylistic changes, therefore, the historian of art has two further tasks: to investigate both the various purposes for which pictures have been used and the cognitive environments of those who used them.

The primacy of practice in the development of knowledge is one of materialism’s fundamental tenets. Most arguments supporting it have been strictly philosophical. However, over the past thirty years cognitive science has provided mounting evidence supporting the primacy of practice. Particularly striking is its finding that thought is fundamentally metaphoric—that images emerging from everyday embodied activities not only make ordinary experiences intelligible, but also underpin our more abstract engagements with the world, elaborated in disciplines such as ethics and science. (...) Cognitive science’s implications must now be absorbed into critical realism. Cognitive science bolsters critical realism by providing a scientifically-grounded analysis of the passage from body to mind and the fundamental unity between them, while sustaining their distinctiveness. Its implications for critical realism ripple out in four waves: first, critical realism’s understanding of the mind/body relationship; second, its concepts of the process that connects theory and practice, and what that means for critical realism’s view of intellectual production, the place of metaphor in scientific theorization, and cultural development; its view of culture as a complexwhole; and finally, its theory of human agency as embodied and intentional.

Thesis: Art like science radically affects our perceiving and thinking, and the two are substantially alike in that together--along with an inherited "natural" language system with which they overlap--they enable us to articulate the world. Science has been advanced as the measure of all things: scientific realism. By implication, art pertains to beauty, science truth. Science effects conceptual break-throughs, changes our models of natural order. On the contrary (I argue), as a nonverbal symbol system art similarly affects paradigm-induced expectations. (...) Substantively there is no difference in the way each enables us to articulate or measure the world: symbolic realism. The myth of resemblance as a criterion of representation--imitation as a one-one relation--has, at least since the time of Plato, obscured this truth. Once the distinction between representational and nonrepresentational art falls, the true nature of artist (like scientist) as maker is illumined. The artist, the scientist (disciplinarian), the cosmologist (those responsible for the formulation of so-called natural languages--in time all of us) make the world or, what practically amounts to the same thing, the known, perceived world. This is the claim of the symbolic realist. Is symbolic realism itself only a watershed? What implication does this critique have for assessing the role of the philosopher today? (shrink)
