The Mind as Neural Software? Understanding Functionalism,Computationalism, and Computational Functionalism

Defending or attacking either functionalism or computationalism requires clarity on what they amount to and what evidence counts for or against them. My goal here is not to evaluate their plausibility. My goal is to formulate them and their relationship clearly enough that we can determine which type of evidence is relevant to them. I aim to dispel some sources of confusion that surround functionalism and computationalism, recruit recent philosophical work on mechanisms and computation to shed light on them, and clarify how functionalism and computationalism may or may not legitimately come together.     

Non‐Classical Knowledge

The Knower paradox purports to place surprising a priori limitations on what we can know. According to orthodoxy, it shows that we need to abandon one of three plausible and widely‐held ideas: that knowledge is factive, that we can know that knowledge is factive, and that we can use logical/mathematical reasoning to extend our knowledge via very weak single‐premise closure principles. I argue that classical logic, not any of these epistemic principles, is the culprit. I develop a consistent theory validating all these principles by combining Hartry Field's theory of truth with a modal enrichment developed for a different purpose by Michael Caie. The only casualty is classical logic: the theory avoids paradox by using a weaker‐than‐classical K₃ logic. I then assess the philosophical merits of this approach. I argue that, unlike the traditional semantic paradoxes involving extensional notions like truth, its plausibility depends on the way in which sentences are referred to—whether in natural languages via direct sentential reference, or in mathematical theories via indirect sentential reference by Gödel coding. In particular, I argue that from the perspective of natural language, my non‐classical treatment of knowledge as a predicate is plausible, while from the perspective of mathematical theories, its plausibility depends on unresolved questions about the limits of our idealized deductive capacities.     

Functionalism and inverted spectra

Functionalism, a philosophical theory, has empirical consequences. Functionalism predicts that where systematic transformations of sensory input occur and are followed by behavioral accommodation in which normal function of the organism is restored such that the causes and effects of the subject's psychological states return to those of the period prior to the transformation, there will be a return of qualia or subjective experiences to those present prior to the transform. A transformation of this type that has long been of philosophical interest is the possibility of an inverted spectrum. Hilary Putnam argues that the physical possibilty of acquired spectrum inversion refutes functionalism. I argue, however, that in the absence of empirical results no a priori arguments against functionalism, such as Putnam's, can be cogent. I sketch an experimental situation which would produce acquired spectrum inversion. The mere existence of qualia inversion would constitute no refutation of functionalism; only its persistence after behavioral accommodation to the inversion would properly count against functionalism. The cumulative empirical evidence from experiments on image inversion suggests that the results of actual spectrum inversion would confirm rather than refute functionalism.     

THE NEW FUNCTIONALISM

SJÖBERG, L. The new functionalism. Scand. J. Psychol. , 1971, 12, 29–52. – The paper reviews the development of Brunswik's probabilistic functionalism. Brunswik's major contribution is held to be his consistent emphasis of the importance of the ecology. Brief reviews are then given of the many recent applications of probabilistic functionalism in perception, learning, and applied psychology. Finally, a mentalistic approach to psychology is considered as an alternative to functionalism.     

Philosophical parrhesia as aesthetics of existence

According to some interpreters, Foucault's encounter with the Greek and Roman ethics led him to reconsider his earlier work and to turn away from politics. Drawing mostly from Foucault's last and hitherto unpublished lecture course, this paper argues that Foucault's turn to ethics should not be interpreted as a turn away from his previous work, but rather as its logical continuation and an attempt to resolve some of the outstanding questions. I argue that the 1984 lectures on parrhesia should be interpreted as Foucault's philosophical apology, as an attempt to defend himself against the charges of moral and epistemological nihilism, which were raised in response to his earlier work. In his last lectures, the Nietzschean Foucault somewhat surprisingly describes his earlier work as authentic Socratic philosophy and as ethical practice of freedom. In the conclusion, I assess the plausibility of Foucault's apology and speculate in which direction his work might have developed, had it not been cut off by his death.     

On Making an Effort

Abstract

This aper is in the main a critical study of Robert Kane's account of the nature of Free Choice. I begin by briefly describing Kane's theory. I then consider four questions about a concept that is central to his account—viz., the concept of an Effort of Will. I argue that Kane's position affords satisfactory answers to three of these questions. Reflection on the fourth and final question, however, reveals a problem for Kanean Libertarianism. The problem, in brief, is this. It can be shown that the plausibility of Kanean Libertarianism is inversely proportional to the plausibility of a certain principle of agency. The latter is at least fairly plausible, so the former is at best fairly implausible. This is a strike against Kanean Libertarianism. I conclude by drawing two general lessons from the preceding discussion.     

Kierkegaard’s Notion of a Divine Name and the Feasibility of Universal Love

Kierkegaard's well‐known analysis of the self, in the first part of his work The Sickness unto Death (1849), presents, even if only in passing, the somewhat enigmatic notion of “divine name.” In this article I offer an interpretation of Kierkegaard's analysis and suggest that the notion of a divine name be understood as expressing the conception of human beings as possessing (what I call) “individual essence.” I further demonstrate that it is this quality that makes a human being a self, namely, the individual that he or she is. In addition to defending the exegetical and substantial plausibility of this conception, I show how it opens the way to affirming the feasibility of universal love.     

Gauthier and the Capacity for Morality

In Morals by Agreement, David Gauthier tries to provide a justification of morality from morally neutral premises within the constraints of an instrumental conception of reason. But his reliance on this narrow conception of reason creates problems, for it suggests that moral motivation is self-interested. However, Gauthier holds that to act morally is to act for the sake of morality and others, not oneself. An individual who so acts has what he calls an affective capacity for morality. He attempts to reconcile the tension between the self-interested account of moral behaviour and the affective capacity for morality by showing that the latter could develop from the former without violating the constraints of instrumental rationality. I argue, first, that his account is incomplete and assumes what it has to demonstrate; and, second, that this cannot be remedied with any plausibility. Finally, I argue that Gauthier covertly relies on a substantive claim about human good that is inconsistent with the instrumental conception of reason. This revised version was published online in July 2006 with corrections to the Cover Date.     

ON THE PRAGMATICS OF SOCIAL THEORY: THE CASE OF ELIAS'S “ON THE PROCESS OF CIVILIZATION”

This paper proposes a new approach to the study of sociological classics. This approach is pragmatic in character. It draws upon the social pragmatism of G. H. Mead and the sociology of texts of D. F. McKenzie. Our object of study is Norbert Elias's On the Process of Civilization. The pragmatic genealogy of this book reveals the importance of taking materiality seriously. By documenting the successive entanglements between human agency and nonhuman factors, we discuss the origins of the book in the 1930s, how it was forgotten for 30 years, and how in the mid‐1970s it became a sociological classic. We explain canonization as a matter of fusion between book's material form and its content, in the context of the paperback revolution of the 1960s, the events of May 1968, and the demise of Parsons’ structural functionalism, and how this provided Elias with an opportunity to advance his model of sociology.     

Functional Concepts,Referentially Opaque Contexts,Causal Relations,and the Definition of Theoretical Terms

In his recent article, ``Self-Consciousness', George Bealer has set outa novel and interesting argument against functionalism in the philosophyof mind. I shall attempt to show, however, that Bealer's argument cannotbe sustained.In arguing for this conclusion, I shall be defending three main theses.The first is connected with the problem of defining theoreticalpredicates that occur in theories where the following two features arepresent: first, the theoretical predicate in question occurswithin both extensional and non-extensional contexts; secondly, thetheory in question asserts that the relevant theoretical states enterinto causal relations. What I shall argue is that a Ramsey-styleapproach to the definition of such theoretical terms requires twodistinct quantifiers: one which ranges over concepts, and theother which ranges over properties in the world.My second thesis is a corollary: since the theories on whichBealer is focusing have both of the features just mentioned, and sincethe method that he employs to define theoretical terms in his argumentagainst functionalism does not involve both quantifiers that range overproperties and quantifiers that range over concepts, that method isunsound.My final thesis is that when a sound method is used, Bealer's argumentagainst functionalism no longer goes through.The structure of my discussion is as follows. I begin by setting out twoarguments – the one, a condensed version of Bealer's argument, andthe other, an argument that parallels Bealer's argument very closely.The parallel argument leads to a conclusion, however, that, rather thanbeing merely somewhat surprising, seems very implausible indeed. Forwhat the second argument establishes, if sound, is that there can betheoretical terms that apply to objects by virtue of their first-orderphysical properties, but whose meaning cannot be defined via aRamsey-style approach.Having set out the two parallel arguments, I then go on to focus uponthe second, to determine what is wrong with it. My diagnosis will bethat the problem with the argument arises from the fact that it involvesdefining a theoretical term that occurs both inside and outside ofopaque contexts, for the method employed fails to take into account thefact that the types of entities that are involved in the relevanttruthmakers are different when a sentence occurs within an extensionalcontext from those involved when a sentence occurs within anon-extensional context.I then go on to discuss how one should define a theoretical term thatoccurs within such theories, and I argue that in such a case one needstwo quantifiers, ranging over different types of entities – on theone hand, over properties and relations, and the other, over concepts. Ithen show that, when such an approach is followed, the argument inquestion collapses.I then turn to Bealer's argument against functionalism, and I show,first, that precisely the same method of defining theoretical terms canbe applied there, and, secondly, that, when this is done, it turns outthat that argument is also unsound.Next, I consider two responses that Bealer might make to my argument,and I argue that those responses would not succeed.Finally, I conclude by asking exactly where the problem lies in the caseof Bealer's argument. My answer will be that it is not simply the factthat one is dealing with a theoretical term that occurs in bothextensional and non-extensional contexts. It is rather the combinationof that feature together with the fact that the theory in questionasserts that the relevant type of theoretical state enters into causalrelations. For the first of these features means that the Ramseysentence for the theory must involve quantification over concepts, whilethe presence of the second feature means that the Ramsey sentence mustinvolve quantification over properties in the world, and so no attemptto offer a Ramsey-style account of the meaning of the relevanttheoretical term can succeed unless one employs both quantification overconcepts and quantification over properties. Bealer, however, in hisargument against functionalism, uses a method of defining theoreticalterms that does not involve both types of quantification, and it isprecisely because of this that his argument does not in the end succeed.     

Parallelism and Functionalism

It has recently been argued by Paul Thagard (1986) that parallel computational models of cognition demonstrate the falsity of the popular theory of mind known as functionalism. It is my contention that his argument is seriously mistaken and rests on a misunderstanding of the functionalist position. While my primary aim is to defend functionalism from Thagard's attack, in the process I hope to provide some much needed clarification of matters both philosophical and computational. Since I intend to untangle issues that are often troublesome in cognitive science, the paper should prove useful even for those unfamiliar with Thagard's original piece.     

Social structures and social functions: The emancipation of structural analysis in sociology∗

Starting from R. K. Merton's now classic criticism of ‘holistic’ functionalism, i.e. of a functionalism which postulates social unity, universality and functional in‐dispensability, the author stresses certain implications of this criticism more than they have been stressed hitherto. Classical and holistic functionalism) from H. Spencer, B. Malinowski, A. R. Radcliffe‐Brown, etc to T. Parsons, postulates certain total unities (a global culture, an integrated system, etc.) in which each item (existence, actions, structures, etc.) is considered and defined on the grounds of its consequences for the maintenance of the system as a whole; therefore holistic functionalism as a method is, in effect, the study of the consequences of the system on the items that compose it, since each of these items is defined within the sphere of the system and of its integrative functions. Merton's ‘neo‐functionalism’, on the other hand, is remarkable not only in that it takes into account the ‘dysfunctional’ and ‘nonfunctional’ consequences of certain items on the system, but more especially because, within the context of functional analysis, it stresses the possible existence of structural substitutes and alternatives of functions, and therefore of latent structures which are foreign to objective functional consequences, as well as being able to deal with unanticipated and unexpected items and their consequences on the system. ‘Neo‐functionalism’, which is susceptible of further development, is not limited to the study of the consequences of the system on its items: it can also reverse this scheme and study the consequences of certain items on the system. Merton's criticism of holistic functionalism therefore implies a broadening of the scientific resources of this method and a renewal of its interpretative scheme, thanks to which functional analysis ceases to appear as ‘the? method of explaining sociology as a science, and becomes an interpretative method which complements the analysis of social structures and relations. Seen in this light the concept of structure becomes emancipated and independent of the concept of system and function; whereas, within the framework of universal functionalism, it was ancillary to the concept of function. Finally, latent structures and unconscious structures, conditions of possibility and subjective dispositions are favourable to social structures and social relations, not excluding those that are neither visible nor observable. This analysis, the author notes, is extremely meaningful and has great possibilities of development, especially in view of the structuralism recently to be noted in the human and social sciences: anthropology, history, linguistics, etc.     

Wilhelm Wundt's contribution to John Dewey's functional psychology

John Dewey's functionalism and instrumentalism arose from his defense of a teleological understanding of human activity and intelligence. E. B. Titchener's counterdefense of structuralism in the late 1890s placed Wundt's psychological methodology in opposition to functionalism. However, investigations that convincingly re-interpret Wundt instead permit the disclosure of much fundamental agreement. Examination of Dewey's earliest work shows that his commitment to teleology, with its attendant organicist and voluntarist orientation, arose from an early allegiance to G. S. Morris's Aristotelianized neo-Hegelianism and an inspirational debt to Wundt's psychology and philosophy. William James's influence on Dewey's development toward instrumentalism must be accordingly de-emphasized.     

Zorba The Buddha: Capitalism,Charisma and the Cult of Bhagwan Shree Rajneesh

This essay suggests a new way of understanding the notorious Indian guru, Bhagwan Shree Rajneesh, by examining the intimate relationship between his religious teachings and his business practices. Rajneesh's ideal was in fact that of ‘Zorba the Buddha’, the perfect synthesis of the spiritual and material, the religious and capitalist impulses. After analysing and criticizing the classical Weberian concept of ‘charisma’, this paper argues that charismatic authority is by no means incompatible with bureaucratic organization or rational business practices. On the contrary, not only can charismatic authority be combined with a complex bureaucratic organization, but it can also be transformed into a kind of ‘commodity’ which is bought and sold on the consumer market. Rather than a ‘routinization of charisma’ what we find in the Rajneesh movement is a kind of ‘commodification’ and ‘commercialization’ of charisma. Bhagwan offered (and sold) his followers the promise of the same charismatic authority and divine freedom which he himself enjoyed (though, in practice, this authority could never actually be attained by any of his followers). Moreover, charismatic authority became the basis for a new kind of bureaucratic organization in Rajneesh's world-wide network of commercial enterprises—an organization characterized by a high degree of fluidity and flexibility, able to adapt itself rapidly to meet the changing demands of its consumer market.     

FUNCTIONALISM, FALLIBILISM, AND ANTI–FOUNDATIONALISM IN WIEMAN'S EMPIRICAL THEISM

Abstract. Empirical philosophy of religion is usually appraised in light of its theological uses, rather than in terms of its relation to philosophical forms of empiricism. The present paper examines the empirical theism of Henry Nelson Wieman by relating it to Carl Hempel's critique of functionalism, Karl Popper's use of falsifiability, and the growth of post–empiricist anti–foundationalism in epis–temology. It is concluded that Wieman's argument commits the fallacy of affirming the consequent; that his theistic perspective nevertheless offers an important heuristic device in line with fal–libilism, and that his radical empiricism anticipates recent anti–foundationalist trends.     

Why Naturalism?

My goal in this paper is to explain what ethical naturalism is, to locate the pivotal issue between naturalists and non-naturalists, and to motivate taking naturalism seriously. I do not aim to establish the truth of naturalism nor to answer the various familiar objections to it. But I do aim to motivate naturalism sufficiently that the attempt to deal with the objections will seem worthwhile. I propose that naturalism is best understood as the view that the moral properties are natural in the sense that they are empirical. I pursue certain issues in the understanding of the empirical. The crux of the matter is whether any synthetic proposition about the instantiation of a moral property is strongly a priori in that it does not admit of empirical evidence against it. I propose an argument from epistemic defeaters that, I believe, undermines the plausibility of a priorism in ethics and supports the plausibility of naturalism.     

Pragmatism and Radical Empiricism

A rational reconstruction of James's doctrine of pure experience is attempted, showing how it can be formulated in terms of a Ramsey sentence so that its credibility is comparable to contemporary functionalism about the mind. Whereas functionalism treats only mental predicates as theoretical terms and quantifies over physical objects, Jamesian 'global-functionalism' treats both mental and physical predicates as theoretical terms and quantifies over pure experience. Rehabilitated in this way, the doctrine of pure experience is a fit partner for Jamesian pragmatism. When James says that pragmatism guides us in the course of our experience, this 'experience' must be understood as ultimately pure experience. Pure experience is just what appears , pre-conceptually, and Ramsey-sentence analysis shows how James's employment of the pre-conceptual demonstrative that can refer to pure experience with conditions of identity given by its physical or mental properties, while being itself 'colourless', neither mental nor physical. It is concluded that functionalists about the mind have reason to be global-functionalists about mind and body, in just the way that James's doctrine of pure experience lays out; and Jamesian pragmatists should also accept his radical empiricism.     

Reply to Krellenstein on Parallel Computation

I recently argued that the position in the philosophy of mind called functionalism is undermined by the importance of recent work on parallel computation (Thagard, 1986). In reply, Krellenstein (1987) contends that parallelism does not have the philosophical significance I claimed for it. Although his contentions are plausible if one focuses on what is in principle computationally possible, they fail if one looks at real problems.     

Proper function and defeating experiences

Jonathan Kvanvig has argued that what he terms “doxastic” theories of epistemic justification fail to account for certain epistemic features having to do with evidence. I’m going to give an argument roughly along these lines, but I’m going to focus specifically on proper function theories of justification or warrant. In particular, I’ll focus on Michael Bergmann’s recent proper function account of justification, though the argument applies also to Alvin Plantinga’s proper function account of warrant. The epistemic features I’m concerned about are experiences that should generate a believed defeater but don’t. I’ll argue that proper functionalism as it stands cannot account for the epistemic effects of these defeating experiences—or, at least, that it can only do so by embracing a deeply implausible view of our cognitive faculties. I’ll conclude by arguing that the only plausible option Bergmann has for modifying his theory undercuts the consideration that motivates proper functionalism in the first place.     

A Comedy We Believe In: A Further Look at Sartre's Theory of Emotions

This paper discusses recent interpretations of Jean‐Paul Sartre's early theory of emotions, in particular his Sketch for a Theory of the Emotions. Despite the great interest that Sartre's approach has generated, most interpretations assume that his approach fails because it appears to be focussed on ‘malformed’, ‘irrational’ or ‘distorted’ emotions. I argue that these criticisms adopt a rationalistic or epistemically biassed perspective on emotions that is wrongly applied to Sartre's text. In my defence of Sartre I show that the directional fit of emotions is not towards an evaluatively loaded world which is independently given and, at best, represented by emotions, but towards a world shaped through the impact of emotions themselves. Sartre's idea of emotions ‘magically transforming’ reality for the subject so that the latter is better able to cope with problematic aspects of practically relevant situations encapsulates the world‐shaping capacities of emotions, which are thus not reserved for a restricted class of emotions. Recognition of the transformative powers of emotions will also direct attention away from their seemingly representative elements to their normative and practical aspects and offer a new basis for delineating the criteria for judging them. The plausibility of this position is discussed with reference to some of Sartre's examples, such as fear, sadness and horror, but also with reference to Joan Didion's account of grief in The Year of Magical Thinking.
