The scholarly enterprise known as the psychology of religion can be understood as the psychological study of religious practice, belief, and experience. With one foot in the stream of psychological theory and research and the other in the flow of religious experience and understanding, it seeks to illuminate the latter through use of the former. In other words, religion becomes the object of psychological analysis, that is, in some sense subordinated to psychology. This relative inequality raises significant methodological issues for (...) anyone attempting to study religion in this way. In particular, one is confronted with the prospect of becoming reductionistic, that is, of explaining what is in fact a complex phenomenon in terms too simple and uni-dimensional, distorting the object of study in the process.

Purpose: To examine the role of reductionism in the theoretical development of modern physics -- more specifically, in the quest for a complete unification of physical theory -- from the perspective of radical constructivism (RC). Approach: Some central features of the impact of RC on philosophy of physics are pointed out: its position of scientific relativism, with important implications for the validation of scientific propositions; and the notion of sharing constructed knowledge among individual knowers and its consequences for (...) science teaching. The issue of reductionism is then discussed with regard to (a) the hierarchical explanatory ordering of physical phenomena; (b) the idea of a "theory of everything" (TOE); and (c) some of its implications for the methodology and sociology of science. Findings: It is argued that the ontological status of the hierarchical structuring inherent in the sought-after TOE will depend on the individual knower's epistemic position concerning the notion of truth in science. In the relativist epistemology of RC, any true/false dichotomy of theories is without meaning. A hierarchical ordering is just one of many possible strategies that may be chosen for the construction of physical theories; and such a strategy may then be considered successful only to the extent that it yields a theory that is viable. Implications: The paper serves as an illustration of the impact of RC on the ongoing search in physics for a "final theory.". (shrink)

The trivial neuron doctrine (TND) holds that psychology merely depends on neurobiology. The radical neuron doctrine (RND) goes further and claims that psychology is superfluous in that neuroscience can “replace it.” Popular among RND notions of “replacement” is “reduction,” and in our commentary we challenge Gold & Stoljar (G&S) to make clear their distinction between merely depends on (TND) and is reducible to (RND). G&S give us a TND–RND distinction that is a distinction without a difference; a defensible TND–RND (...) distinction must have a metaphysical basis. We suggest a denial of compositionalism as such a basis. (shrink)

Scientists have always attempted to explain the world in terms of a few unifying principles. In the fifth century B.C. Democritus boldly claimed that reality is simply a collection of indivisible and eternal parts or atoms. Over the centuries his doctrine has remained a landmark, and much progress in physics is due to its distinction between subjective perception and objective reality. This book discusses theory reduction in physics, which states that the whole is nothing more than the sum of its (...) parts: the properties of things are directly determined by their constituent parts. Reductionism deals with the relation between different theories that address different levels of reality, and uses extrapolations to apply that relation in different sciences. Reality shows a complex structure of connections, and the dream of a unified interpretation of all phenomena in several simple laws continues to attract anyone with genuine philosophical and scientific interests. If the most radical reductionist point of view is correct, the relationship between disciplines is strictly inclusive: chemistry becomes physics, biology becomes chemistry, and so on. Eventually, only one science, indeed just a single theory, would survive, with all others merging in the Theory of Everything. Is the current coexistence of different sciences a mere historical venture which will end when the Theory of Everything has been established? Can there be a unified description of nature? Rather than an analysis of full reductionism, this book focuses on aspects of theory reduction in physics and stimulates reflection on related questions: is there any evidence of actual reduction? Are the examples used in the philosophy of science too simplistic? What has been endangered by the search for (the) ultimate truth? Has the dream of reductionist reason created any monsters? Is big science one such monster? What is the point of embedding science Y within science X, if predictions cannot be made on that basis? (shrink)

With the advent of the Human Genome Project there have been many claims for the genetic origins of complex human behavior including insanity, criminality, and intelligence. But what does it really mean to call something 'genetic'? This is the fundamental question that Sahotra Sarkar's book addresses. The author analyses the nature of reductionism in classical and molecular genetics. He shows that there are two radically different kinds of reductionist explanation: genetic reduction (as found in classical genetics) and physical reduction (...) (found in molecular genetics). This important book clarifies the meaning of the term 'genetic', shows how molecular studies have affected genetics, and provides the philosophical background necessary to understand the debates over the Human Genome Project. It will be of particular interest to professionals and students in the philosophy of science, the history of science, and the social studies of science, medicine, and technology. (shrink)

The contrast between the strategies of research employed in reductionism and holism masks a radical contradiction between two different scientific philosophies. We concentrate in particular on an analysis of the key philosophical issues which give structure to holistic thought. A first (non-exhaustive) analysis of the philosophical tradition will dwell upon: a) the theory of emergence: each level of organisation is characterised by properties whose laws cannot be deduced from the laws of the inferior levels of organisation (Engels, Morgan); (...) b) clarification of the relations between the “whole” and the “parts” (Woodger, Needham); c) the ontological or epistemological nature of the emergent properties; are they a phenomenological reality or solely an artefact of the state of our knowledge? (Pepper, Henle, Hempel and Oppenheim); d) the proposition of the holistic theoretical and methodological model ( Novikoff, Feibleman). I then go on to examine the differences that exist between the reductionist and the holistic approaches at various levels of analysis: that is to say, the differences which affect their ontologies, methodologies and epistemologies respectively. I attempt to understand the spirit of a holistic approach to ecology by analyzing the major work of E.P. Odum Fundamentals of ecology (1953, 1959, 1971). I set forward what might be meant by the “holistic approach”, which is implicated in all the different levels of organisation at which the problem of “complexity” is debated. Ecology presents itself as an “holistic science” and Odum’s book offers a vision of the world which dates far back in the history of philosophy. By looking at the three different editions of this fundamental text on ecology, we may become aware of the evolution of Odum’s thought. In fact, only in the third and last edition is there a conscious appropriation of the holistic approach (by using the theoretical models of Feibleman who, for his part, refers to Novikoff). However, even when formally referring to the theory of emergence (that is to say the ontological nucleus of every holistic approach), Odum’s systemic analysis presents the same logical errors, which push him back into the reductionist domain. Above all, in his examination of the main concepts of “population”, “community” and “ecosystem”, there is a misunderstanding of the profound difference between “collective properties” and “emergent properties”. Moreover, the cybernetic models of Odum’s systemic analysis (introduced into ecology by Margalef), allowed him to vastly oversimplify his methodological task: in fact, neither how many levels nor which levels of organization are fundamental for the study of each individual level is clearly marked. Finally, Odum analyses the ecosystem as composed of energetic flux and cycles of matter, referring to the trophic-dynamic vision of Lindeman. That is to say, in my opinion, he juxtaposes a reductionistic methodology and epistemology to an holistic ontology. (shrink)

The neuroscience revolution has revived interpretations of religious experiences as wholly dependent on biological conditions. William James cautioned against allowing such neurological reductionism to overwhelm other useful perspectives. Contemporary psychologists of religion have raised similar cautions, but have failed to engage James as a full conversation partner. In this article, we present a contemporary, applied version of James's perspective. We clarify the problem by reviewing specific James-like contemporary concerns about reductionism in the neuropsychological study of religion. Then, most (...) centrally, we employ three of James's conceptual tools—pragmatism, pluralism, and radical empiricism—to moderate contemporary reductionism. Finally, we point to a constructive approach through which neuroscientists might collaborate with scholars in the humanities and psychosocial sciences, which is consistent with our conclusion that it is often no longer fruitful to separate neurobiological studies from studies that are psychosocial or sociocultural.

Derek Parfit influentially defends reductionism about persons, the view that a person’s existence just consists in the existence of a brain and body and the occurrence of a series of physical and mental events. Yet some critics, particularly Mark Johnston, have raised powerful objections to Parfit’s reductionism. In this paper, I defend reductionism against Johnston. In particular, I defend a radical form of reductionism that Buddhist philosophers developed. Buddhist reductionism can justify key features of (...) Parfit’s position, such as the claims that personal identity is not what matters and can also be indeterminate. Furthermore, Buddhist reductionism can avoid Johnston’s objections to Parfit’s reductionism. I conclude that reductionists have good reasons to favor Buddhist reductionism over Parfit’s version.

Epicurus' "On Nature" 25 is the key text for anti-reductionist interpretations of Epicurus' philosophy of mind. In it, Epicurus is trying to argue against those, like Democritus, who say that everything occurs 'of necessity,' and in the course of this argument, he says many things that appear to conflict with an Identity Theory of Mind and with causal determinism. In this paper, I engage in a close reading of this text in order to show that it does not contain any (...) clear statement of either a doctrine of radically emergent properties and "downwards causation" (contra David Sedley) or of the non-reducibility of the mental to the atomic (contra Julia Annas). I argue that Epicurus' main thesis is that we cannot consistently argue against our conception of ourselves as rational agents, and that it is our reason that allows us to reform our characters, control our actions, and blame and praise one another appropriately. The way that Epicurus describes the development and causal efficacy of reason in "On Nature" book 25 is consistent both with reductionism and (more surprisingly) with causal determinism. (shrink)

In this paper I argue that the anti-reductionist thesis supports a case for the uselessness of intentional idioms in the interpretation of highly flexible, self-modifying agents that I refer to as “hyperplastic” agents. An agent is hyperplastic if it can make arbitrarily fine changes to any part of its functional or physical structure without compromising its agency or its capacity for hyperplasticity. Using Davidson’s anomalous monism (AM) as an exemplar of anti-reductionism, I argue that AM implies that no hyperplastic (...) could use intentional psychology to predict its future intentional states or the psychological consequences of self-alterations. This is because AM implies there would be no laws allowing the hyperplastic to infer the psychological consequences of its self-alterations. This implies that no generalisations linking current to future psychological states would hold either - these could always be defeated by a self-intervention carried out by the hyperplastic. By the same token, neither hyperplastics nor human interpreters could use intentional psychology to understand the behaviour of other hyperplastics. Radical interpretation of hyperplastic agents - if such there were - would be impossible. It follows that were humans to become hyperplastic posthumans, intentional psychology would have to be instrumentally eliminated because neither the capacity nor the linguistic idiom for attributing propositional attitudes would retain predictive or hermeneutic utility.

As a critic, I am in the unenviable position of agreeing with nearly all of what Mark does in this lucid, erudite and creative book. My comments will hence not be aimed at showing what he got wrong, as much as an attempt from a Madhyamaka point of view to suggest another way of seeing things, in particular another way of seeing how one might think of how Madhyamaka philosophers, such as Någårjuna and Candrak¥rti, see conventional truth, our engagement with (...) conventional truth, and the status of persons. I suspect that this alternative is also in the minds of earlier Buddhist philosophers, and that Madhyamaka may be more an explicit working out of ideas implicit in the tradition than a radical break. If this suspicion—for which I will not argue here—is correct, this alternative is also available to those to whom Mark refers as “reductionists.” I think that this way of seeing things may put certain ideas in Buddhist philosophy into better focus, and may indeed make them more attractive as well.

Resumo: O projeto semântico de Davidson toma a forma de reducionismo que visa explicar as noções intencionais com base em noções puramente extensionais. O objetivo desse trabalho consiste na investigação do fracasso do projeto de Davidson como um argumento indireto contra sua suposição segundo a qual a chamada interpretação radical seria o fundamento do significado linguístico e do pensamento. Abstract: Davidson's semantic program is a form of semantic reductionism that aims to account for intensional notions on a purely (...) extensional basis. My aim in this paper is not to show that Davidsons fails in addressing the so-called extensionality problem. That is no novelty. Even Davidsonians recognize Davidson's failure. My main goal is to explore Davidson's failure as an indirect argument against his key assumption that the radical interpretation is the basis of sense and hence the possibility of thought. There is no priority of language over thought. This is a remnant of the so-called linguistic turn that Davidson inherited from the analytical tradition. The moral is the following: we must come back to Lockean common sense that to learn a natural language and to translate an alien tongue into our own is merely to learn a vehicle for communicating and expressing thoughts we have already had.

The study of mental illness by the methods of molecular genetics is still in its infancy, but the use of genetic markers in psychiatry may potentially lead to a Virchowian revolution in the conception of mental illness. Genetic markers may define novel clusters of patients having diverse clinical presentations but sharing a common genetic and mechanistic basis. Such clusters may differ radically from the conventional classification schemes of psychiatric illness. However, the reduction of even relatively simple Mendelian phenomena to molecular (...) genetics has been shown to be a surprisingly complex and problematic enterprise. Mental illnesses exist at many levels of including social, environmental, and developmental interactions. Reductionistic shifts in the classification of such a disease entity will have to address the interlevel dynamics that take place within the structure of theories of mental illness. The question of how molecular analysis of psychiatric disease will impact on the structure of existing theories and classification systems is the central topic of this paper. (shrink)

The concept of information and its relation to biosemiotics is a major area of contention among biosemioticians. Biosemioticians influenced by von Uexküll, Sebeok, Bateson and Peirce are critical of the way the concept as developed in information science has been applied to biology, while others believe that for biosemiotics to gain acceptance it will have to embrace information science and distance biosemiotics from Peirce’s philosophical work. Here I will defend the influence of Peirce on biosemiotics, arguing that information science and (...) biosemiotics as these were originally formulated are radically opposed research traditions. Failure to appreciate this will undermine the challenge of biosemiotics and other anti-reductionist traditions to mainstream science with its reductionist ambition to explain everything through physics. However, for this challenge to be successful, it will be necessary to respond to criticisms of Peircian ideas, jettisoning ideas that are no longer defensible and integrating ideas allied to his anti-reductionist agenda. Here I will argue that the natural philosophy of Gilbert Simondon, offering a searching critique of the application of the new concept of information and cybernetics to the life and human sciences, provides the means to defend and advance Peirce’s core ideas and thereby defend post-reductionist biosemiotics.

Shaun Gallagher calls for a radical rethinking of the concept of nature and he resists reduction of phenomenology to computational-neural science. However, classic, reductionist science, at least in contemporary computational guise, has the resources to accommodate insights from transcendental phenomenology. Reductionism should be embraced, not feared.

Consider statements like ``Machines will never be able to think'' or ``You cannot turn a cat into a dog''. Many people will find such propositions evident, but we have learned to be cautious. 100 years from now things might look very different; it seems unduly dogmatic to insist on todays opinions as unrevisable points of reference, disallowing future breakthroughs in computer science or biology. The scientific outlook presupposes and enhances a high degree of curiosity and it seems a good idea (...) to generally keep one's meanings flexible so as to master break-downs of everyday understanding induced by unforseen circumstances, science or technology. Such intuitions are at the heart of Quine's philosophy. According to him we find ourselves enmeshed within a web of belief that joins together past and present attitudes, cognitive procedures and evidential tests. The strands show various degrees of coherence and interconnectedness and there are no general rules on how to proceed in case something unexpected happens. Sometimes it is ignored, sometimes it is explained away and sometimes it induces more or less extensive changes in our predictive and behavioural patterns. This seems to be the lesson drawn from the Vienna Circle's battle against metaphysics. Philosophers like Putnam, Kripke and Davidson have, it is true, come up with accounts of meaning, necessity and reality that seriously challenge Quine's indeterminacy of translation and ontological relativity, re-introducing elements of a priori presuppositions and (quasi-)transcendental arguments into philosophical discourse. But - compared to Quine's unrelenting insistence on naturalistic first-level talk - those attempts have a free-floating, speculative touch. Quine refuses to engage in elaborate philosophical constructions designed to block the permanent drift of meaning. His is a truly radical position, admirably suggestive and provocative, to be challenged on its own ground. The untenability of a priori truth is suggested by profound experiences that cannot easily be refuted by arguments purporting to show how some more or less exotic sentences could, after all, be held immune from change.1 If the untenability thesis is to be shaken a more down to earth strategy seems to be called for. It would have to be shown that Quine's radical move entails consequences that are highly unattractive even according to its own standards. (shrink)

In 1982 Saul A. Kripke proposed a reconstruction of the central insights of Ludwig Wittgenstein's remarks on rule-following. The reconstruction prominently featured a sceptical challenge which soon was recognised as a new and very radical form of scepticism. According to the challenge there is no fact of the matter which constitutes meaning. As there is no such fact, the first-person authority people intuitively seem to have concerning what they mean is also baseless. In response to the sceptic, many solutions (...) have been proposed. This thesis is about one family of solutions, according to which facts about meaning are sui generis and can neither be reduced to other facts about the world nor to non-semantic facts about the human mind. The non-reductionist proposals by Colin McGinn and Crispin Wright will be assessed in detail and arguments against both will be introduced. The arguments stem only partially from Kripke himself, some are based on recent literature, others are completely new. The emerging situation will be used as a basis to propose an alternative non-reductionism about meaning-facts. (shrink)

As British and American idealism waned, new realisms displaced them. The common background of these new realisms emphasized the problem of the external world and the mind-body problem, as bequeathed by Reid, Hamilton, and Mill. During this same period, academics on both sides of the Atlantic recognized that the natural sciences were making great strides. Responses varied. In the United States, philosophical response focused particularly on functional psychology and Darwinian adaptedness. This article examines differing versions of that response in William (...) James and Roy Wood Sellars. James viewed the mind as a “fighter for ends.” His neutral monism, by taming the mind-body problem and the problem of the external world, provided a secure metaphysics of mind as functional activity. In contrast, Sellars ’s scientific realism endorsed physical reality but was not mechanistic or reductionist. His critical realism and evolutionary naturalism offered novel metaphysical and epistemological positions in comparison with other American and British realisms. James and Sellars are distinguished from British philosophy in 1890–1918 in the types of realism they endorsed and in their success at introducing Darwinian evolutionary considerations and functional psychology into mainstream philosophy.

William James undertook to steer his way between a rationalistic system that was not empirical enough and an empirical system so materialistic that it could not account for the value commitments on which it rested. In arguing against both the absolutists (gnostics) and the empiricists (agnostics), he defined a position of pluralistic moralism that seemed equally distant from both, leaving himself vulnerable to the criticism that he had rescued morality from scientism only by reducing religion to morals. Such criticism, however, (...) ignores distinctions James made between religion and theology and between monistic theology and dualistic theology. When these distinctions are taken into account, it becomes evident that James can be criticized for reducing religion to morality only from the point of view of either absolute monism or religious humanism and that radical empiricism not only embraces a significant number of nonmoral religious experiences but also leaves open the possibility of belief in the particular historical God of traditional Christianity.

Semantic analysis of contemporary philosophical inquiry is the core problem, and Quine is undoubtedly in the twentieth century conducted to explore the semantic engineering裡arduous, the most influential of modern thinkers. However, although the impact of Quine's great, he semantics regardless of the stance taken by the natural person has not yet been fully satisfied instruction understanding. On the one hand, the based on Quine's controversial idea of the uncertainty, scholars widely believe that regardless Quine's stance is a natural suspicion regardless (...) of extreme stance: the meaning of the word does not exist. On the other hand, Quine in the construction regardless of its license, but to take a natural tendency to analyze the nature of the so-called "stimulus word meaning" future language sentences as the core foundation of semantics. Thus, Quine's semantic natural stance regardless what is a semantic canceled regardless, have a language or meaning regardless of the orientation of some, not very clear. This paper has two purposes: First, the author regardless above, Quine's natural regardless stance in a number of philosophers to cancel regardless positioning, is the station does not live foot stance; Second, in the text, based on Quine's natural regardless stance can be is portrayed as some kind of weaker version of about regardless, and this stance is more feasible. The investigation of linguistic meaning has been central in contemporary analytic philosophy. Quine is undoubtedly one of the most influential thinkers in the 20 century in this daunting inquiry. Despite his enormous influence, however, Quine's naturalistic perspective on meaning has not been properly understood. On the one hand, Quine's view, presented in the controversial indeterminacy thesis, is widely taken as a radical form of skepticism, namely, meaning does not exist. On the other hand, Quine invokes and heavily relies on the notion of disposition to analyze the idea of ​​stimulus meaning, which lies at the heart of Quine's discussion of linguistic meaning. It does not seem entirely clear whether Quine attempts to eliminate meaning, or to naturalize meaning by reducing it to dispositions. The aim of this paper is argue for two points. First, construing Quine's position as semantic eliminativism, as many do, Quine's position would be in deep trouble. Second, based on a textual basis, Quine's position can be alternatively construed as a modest form of dispositional reductionism, which is more tenable. (shrink)

According to Gold & Stoljar, one cannot consistently be both reductionist about psychoneural relations and invoke concepts developed in the psychological sciences. I deny the utility of their distinction between biological and cognitive neuroscience, suggesting that they construe biological neuroscience too rigidly and cognitive neuroscience too liberally. Then, I reject their characterization of reductionism. Reductions need not go down past neurobiology straight to physics, and cases of partial, local reduction are not neatly distinguishable from cases of mere implementation. Modifying (...) the argument from unification as reduction, I defend a position weaker than the radical but stronger than the trivial neuron doctrine. (shrink)

We have reached the peculiar situation where the advance of mainstream science has required us to dismiss as unreal our own existence as free, creative agents, the very condition of there being science at all. Efforts to free science from this dead-end and to give a place to creative becoming in the world have been hampered by unexamined assumptions about what science should be, assumptions which presuppose that if creative becoming is explained, it will be explained away as an illusion. (...) In this paper it is shown that this problem has permeated the whole of European civilization from the Ancient Greeks onwards, leading to a radical disjunction between cosmology which aims at a grasp of the universe through mathematics and history which aims to comprehend human action through stories. By going back to the Ancient Greeks and tracing the evolution of the denial of creative becoming, I trace the layers of assumptions that must in some way be transcended if we are to develop a truly post-Egyptian science consistent with the forms of understanding and explanation that have evolved within history.

Context: Neurophenomenology, as formulated by Varela, offers an approach to the science of consciousness that seeks to get beyond the hard problem of consciousness. There is much to admire in the practical approach to the science of consciousness that neurophenomenology advocates. Problem: Even so, this article argues, the metaphysical commitments of the enterprise require a firmer foundation. The root problem is that neurophenomenology, as classically formulated by Varela, endorses a form of non-reductionism that, despite its ambitions, assumes rather than (...) dissolves the hard problem of consciousness. We expose that neurophenomenology is not a natural solution to that problem. We defend the view that whatever else neurophenomenology might achieve, it cannot close the gap between the phenomenal and the physical if there is no such gap to close. Method: Building on radical enactive and embodied approaches to cognitive science that deny that the phenomenal and the physical are metaphysically distinct, this article shows that the only way to deal properly with the hard problem is by denying the metaphysical distinction between the physical and the phenomenal that gives the hard problem life. Results: This article concludes by discussing how neurophenomenology might be reformulated under the auspices of a radically enactive and embodied account of cognition. That is, only by denying that there are two distinct phenomena - the physical and the phenomenal - can the neurophenomenological project get on with addressing its pragmatic problems of showing how neuroscientists may be guided by first-person data in their analysis of third-person experimental data, and vice versa. Implications: The topic addressed in this article is of direct value to consciousness studies in general and specifically for the project of neurophenomenology. If the neurophenomenological project is to deal with the hard problem, it must denude itself of its non-reductionist background assumption and embrace a strict identity thesis. Constructivist content: Radical enactive and embodied approaches to mind and consciousness adopt a view of consciousness as a dynamic activity - something an organism enacts in ongoing engagement with its environment. These approaches therefore share with constructivist approaches an action-based view of mind. (shrink)

B. F. Skinner is perhaps even more widely known for his views on science than for his experimental work. His comments on the role of theory in science have been labeled “anti-theoretical,” “ultra-empirical”, “non-theoretical,” “radical,” and worse. His position appears to be both extreme and untenable. Scriven [1] has given us a critique of Skinner that goes beyond mere labeling; it is an examination of the assumptions and implications of such a position.

Materialism as a doctrine is, of course, a part of the history of philosophy, even if it was often a polemical construct, and it took until the 18th century for philosophers to be willing to call themselves materialists. Difficulties also have been pointed out in terms of “continuity,” i.e., does what Democritus, Lucretius, Hobbes and Diderot have to say about matter, the body and the soul all belong in one discursive and conceptual frame? Interestingly, materialism is also a classic figure (...) in the history of medicine, often intersecting with philosophical considerations. Notably, the question of body-soul relations. This is apparent in Galen’s treatise on body and soul and then much more massively in the early modern period (with reference to Galen, but also Lucretius, and Aristotelian naturalism). In the following essay I reflect on the exact nature of early modern medical materialism, its philosophical status and contribution. (shrink)

An overview of the history of the concept of matter highlights the fact that alternative modes of explanation were successively employed. With the discovery of irrational numbers the initial conviction of the Pythagorean School collapsed and was replaced by an exploration of space as a principle of understanding. This legacy dominated the medieval period and had an after-effect well into modernity—for both Descartes and Kant still characterized matter in spatial terms. However, even before Galileo the mechanistic world view slowly entered (...) the scene—the world as chaos, particles in motion. Elevating movement to become the guiding principle in our understanding of matter dominated the main tendency of modern physics until the (end of the) 19th century. The discovery of irreversible processes (radio-activity for example) directed 20th century physics towards an exploration of the meaning of energy-operation. It turned out that even within 20th century physics long-standing legacies prevailed, because an account of the nature of matter continued to be torn apart by atomistic and holistic views—confronted by the problem of constancy and change (radical transformability versus persistence). Concrete, material reality exceeds the scope of any single mode of explanation—an insight that also serves a better understanding of the wave-particle duality. (shrink)

The chief problem for the theory of mind is that of presence. In this paper I offer an explanation of this claim, and I indicate how my own “enactive” approach to mind has tried to address this problem. I also argue that other approaches, such as that undertaken by Hutto and Myin, have side-stepped the problem, instead of addressing it; their position opts for reductionism and eliminativism. This essay has two parts. The first is an exposition of the enactive (...) approach, as I understand it, and the second is a critical evaluation of Hutto and Myin. (shrink)

After an overview of the phenomenology of numinous experience in mysticism, conversion, and related states in psychosis, the intersection and distinction between contemporary transpersonal psychologies of spiritual development and psychodynamic/clinical perspectives on pathological states is addressed from cognitive&endash;developmental, psycho-physiological, personality, and socio-cultural perspectives. Debates about the nature of mystical and conversion experiences have a long history in the psychology of religious experience and raise fundamental methodological issues concerning the potential inclusiveness or narrowness of the human sciences. A genuine psychology of (...) numinous experience and its impact on life histories must find its way between the twin dangers of "over-belief" and false reductionism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Descartes and Husserl. The Philosophical Project of Radical BeginningsMichael K. ShimPaul S. MacDonald. Descartes and Husserl. The Philosophical Project of Radical Beginnings. Albany: State University of New York Press, 2000. Pp. 285. Paper, $21.95.The enormous influence exerted by Descartes on Husserl's phenomenological philosophy cannot be underestimated. Not only is Husserl quite open and explicit about his philosophical debt to Descartes, but the fundamental motivation of the (...) phenomenological [End Page 593] method (directed towards apodeicticity and the purification of consciousness) would most likely be meaningless without reference to the Cartesian precedent. Consequently, almost every exegetical approach to Husserlian phenomenology has at least mentioned the relevance of the Cartesian tradition. Unfortunately, rare has been the phenomenological treatment of Descartes current with the latest scholarship. As an exception to this general shortcoming, MacDonald's book is a most welcome entry into Husserl scholarship.One of MacDonald's main theses is that Descartes and Husserl shared similarities in historical circumstances and, thus, shared similar motives for their "radical beginnings" in philosophy. With regards to Descartes' historical circumstances, by providing a breathtaking overview of sixteenth-century skepticism, MacDonald gives a cogent account of what led to Descartes' attempted construction of an absolute epistemological foundation for philosophy. However, the "conceptual confusions and collapses" of neo-skepticism will "survive the Cartesian overthrow and, like a persistent contagion" (31) reappear in the form of nineteenth-century psychologism. MacDonald does a convincing job of highlighting the skeptical profile of psychologism by providing systematic parallels between the mainstays of neo-skepticism and nineteenth-century psychologism: namely, distrust of objective knowledge, subjective reductionism and epistemological relativism. Accordingly, what motivates Husserl's epoché has both historical and systematic resources in the Cartesian reduction. The point itself is nothing new, and Husserl himself stresses the skepticism of nineteenth-century psychologism, but the scholarship and erudition that inform MacDonald's detailed historical account is to be commended.The truly ambitious aspect of the book, however, is the painstakingly worked out systematic comparison between the respective philosophical projects. In this respect, MacDonald takes two correlated approaches. The first approach takes up the metaphors of discovery and "voyage of exploration" (5) common to both thinkers' writings in order to explicate the meaning of philosophical transformation or "conversion," a "cognitive-affective reorientation of the whole self" (227). However, these metaphors are to be understood as symptomatic of deeper formal parallels between the two thinkers.The second approach begins with the daring claim that "Descartes' and Husserl's formal ontologies are... functionally equivalent" (95), a claim MacDonald proposes to reinforce by examining the structural parallels between Descartes' simple-complex dyad on the one hand and Husserl's part-whole theory as introduced in the Third Logical Investigations. This claim is brought into relief by a reformation of Descartes' conception of "ideas." Rather than restrict the Cartesian conception of ideas to "objective content," MacDonald emphasizes the act-quality of Cartesian ideas (125-7). Thereby an intentional conception of Cartesian ideas is made possible. Anyone familiar with Husserl should not find this surprising: what MacDonald is trying to suggest is a division of Cartesian ideas into noesis and noema, with the "material" aspect of act-ideas finding phenomenological restoration in Husserl's "hyletic data." With these elements in place, MacDonald largely succeeds in constructing a fuller and richer than usual comparison between methodical doubt and the phenomenological reduction (151ff), centered on a non-mystical eidetic intuitionism. MacDonald's ultimate conclusion is [End Page 594] that Husserlian phenomenology, as "first philosophy," is thoroughly consistent with Cartesian metaphysics, now understood as "second philosophy" (243).MacDonald's systematic conclusions are much bolder than one might think, since they are adduced by running against the letter of Husserl's own interpretation of Descartes. The background claim is that Husserl himself did not fully appreciate his debt to Descartes, and it is this exegetical failure that has led to his eventual abandonment of the "Cartesian Way."

In “Two Dogmas”, Quine indicates that Carnap’s Aufbau fails “in principle” to reduce our knowledge of the external world to sense data. This is because in projecting the sensory material to reconstruct the physical world, Carnap gives up the use of operating rules and switches to a procedure informed by general principles. This procedure falls short of providing an eliminative translation for the connective “is at”, which is necessary for the reduction. In dissecting Quine’s objection, I argue that Quine has (...) at best proven the claim that the use of general principles essentially fails the task of radical reductionism. However, in order to establish the conclusion that the Aufbau fails in principle, Quine needs to further vindicate two other claims. They are: first, a switch from operating rules to general principles is necessary; second, the set of general principles Carnap adopts is the best alternative. By disambiguating the notion of “explicit definition” and examining the concept of definability in the Aufbau, I explore the possibility of justifying these two claims that Quine overlooks in his objection. The result suggests that Quine’s objection stands in tension with his radical reductionist reading of the Aufbau. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ideas in the Brain: The Localization of Memory Traces in the Eighteenth CenturyTimo KaitaroPlato suggests in the Theaetetus that we imagine a piece of wax in our soul, a gift from the goddess of Memory. We are able to remember things when our perceptions or thoughts imprint a trace upon this piece of wax, in the same manner as a seal is stamped on wax. Plato uses this metaphor (...) to explain the errors which arise when we mistake something for something else: we connect the perception of an object with the trace belonging to another. The metaphor can also be used in explaining differences in people’s mnestic capacities: rapid learning and forgetting correspond to soft wax, impure wax results in muddled traces, etc.1 If we locate the traces in the brain instead of in the soul, Plato’s metaphor gains consistency and turns into a testable hypothesis. This move was already made by Quintilian.2So, the metaphor of memory as traces in the brain is evidently not a modern invention. This is easy to understand. To frame the hypothesis one needs only to reflect on how we use objects outside our brains for mnemonic purposes. We conserve ideas by tracing or printing letters and words on paper. We are also able to conserve images in drawings, paintings and prints. What could be more natural than to think of memory as the formation of traces in the brain? The development of even better information storage techniques in the form of pictures, symbols, and signs provides the metaphor extra plausibility. Plato’s seal allows us to imagine the imprint of a person’s likeness, but modern techniques of information storage and retrieval make it even easier to imagine memory in general as the formation of material traces.Explaining memory in terms of material traces could, of course, be taken [End Page 301] to mean that the formation of material traces in the brain is merely a necessary condition of memory. But one could also take a more reductionistic stance which identifies memory with the formation of material traces. Furthermore, one could identify specific mental items (sensations, ideas, memories) with specific physiological events or anatomical entities in the brain. This seems especially plausible if we imagine that the traces in the brain are as discrete and separate as ideas or memories are in our minds. Since the traces we form or print on paper consist of discrete letters and words, the thought that the traces in the brain are equally discrete and separate comes easily. Plato, in fact, made separateness a condition for the memory to work properly: it is not easy to read signs printed on one another.3 Of course, no traces are actually visible in the brain. But they are easy to imagine, as it is to imagine explanations of psychological phenomena, such as association, based on these traces.At the end of the seventeenth century, explanations of mental phenomena referring to material traces in the brain were used by writers, from Platonists to materialists, who supported widely different theories about the nature of the human mind.4 In fact, as I will show later in this paper, the question of the possible identity of mental entities, like ideas or sensations, with material entities or traces in the brain is relatively independent of the question of the existence of an immaterial soul. Or rather, if there is a systematic connection between the answers proposed to these two questions in the eighteenth century, it is not the connection one would expect. Nowadays we often tend to think of a prototypical materialist as someone who makes radical reductionistic claims about the identity of mental phenomena with brain states. We also tend to think of the eighteenth-century French materialists as “mechanistic.”5 In view of this reputation, it may come as a surprise to find that some eighteenth-century materialists, notably Denis Diderot, were in fact consistent anti-reductionists and opposed to mechanical or mechanistic explanations of the mental.6 In fact, the epithet “mechanistic” is misleading even when applied to the philosopher who is traditionally presented as the paradigmatic example of a “mechanistic materialist,” Julien Offray...

Individualism comes in at least ten modes: ontological, logical, semantic, epistemological, methodological, axiological, praxiological, ethical, historical, and political. These modes are bound together. For example, ontological individualism motivates the thesis that relations are n-tuples of individuals, as well as radical reductionism and libertarianism. The flaws and merits of all ten sides of the individualist decagon are noted. So are those of its holist counterpart. It is argued that systemism has all the virtues and none of the defects of (...) individualism and holism. One such virtue is the ability to recognize that individualism is a system rather than an unstructured bag of opinions--which raises the question whether thorough and consistent individualism is at all possible. Key Words: holism • individualism • system • systemism. (shrink)

Joel Katzav's survey of the philosophy of Grace Andrus de Laguna's philosophy covers a broad range of ideas, and I have selected three for further development and commentary: (1) the relationship between naturalism and analytic philosophy, (2) the relationship between classical and radical empiricism, and (3) the historical question of where to situate a view such as de Laguna's in the history, the present, and the future of philosophy. I suggest that the view belongs with a group I call (...) the ‘New Naturalists’, including Theodore de Laguna, Susanne Langer, Marjorie Grene, Michael Polanyi, and others who keep philosophy closer to developments in natural and social science than is typical for pragmatists, process philosophers, and analytic philosophers. This is a position somewhere between classical and radical empiricism, but which insists that reductionism is too limiting and unwise, even when restricted to being only a method. (shrink)

In Linguistic Bodies, Ezequiel A. Di Paolo, Elena Clare Cuffari and Hanne De Jaegher propose a dialectic method to explain organism’s movements and exchanges, i.e., life inter-actions and evolution, that can also explain the evolution from life to cultural relations, that include linguistic interactions. One of the main questions Linguistic Bodies wants to answer is how to explain human life and culture without a reductive scientific thought. If one defies radical reductionism, one of the central risks is to (...) dissociate physical inquiries from biological investigations. In the book, the authors oppose the analytical mode of thinking present in many natural sciences to a dialectical mode of thinking that would explain living beings’ interactions. It is relevant to question if they succeeded in defending the dialectical model they profess to be the best suited to explain human social phenomena. Following this line of rationale, in this paper, I will, first, show that dialectical methods are over-ambitious and, second, inquire into the anti-reductionist attitude present in the dialectical model advocated in Linguistic Bodies.Key-words: Linguistic bodies, radical reductionism, dialectical model.

Dualist and Reductionist theories of mind disagree about whether or not consciousness can be reduced to a state of or function of the brain. They assume, however, that the contents of consciousness are separate from the external physical world as-perceived. According to the present paper this assumption has no foundation either in everyday experience or in science. Drawing on evidence for perceptual projection in both interoceptive and exteroceptive sense modalities, the case is made that the physical world as-perceived is a (...) construct of perceptual processing and, therefore, part of the contents of consciousness. A finding which requires a Reflexive rather than a Dualist or Reductionist model of how consciousness relates to the brain and the physical world. The physical world as-perceived may, in turn be thought of as a biologically useful model of the world as described by physics. Redrawing the boundaries of consciousness to include the physical world as-perceived undermines the conventional separation of the 'mental' from the physical', and with it the very foundation of the Dualist-Reductionist debate. The alternative Reflexive model departs radically from current conventions, with consequences for many aspects of consciousness theory and research. Some of the consequences which bear on the internal consistency and intuitive plausibility of the model are explored, e.g. the causal sequence in perception, representationalism, a suggested resolution of the Realism versus Idealism debate, and the way manifest differences between physical events as-perceived and other conscious events are to be construed. In the present paper I wish to challenge some of our most deeply-rooted assumptions about what consciousness is, by re-examining how consciousness, the human brain, and the surrounding physical world relate to each other.

This thesis is an attempt to investigate the relation between the views of Wittgenstein as presented by Kripke and Donald Davidson on meaning and linguistic understanding. Kripke’s Wittgenstein, via his sceptical argument, argues that there is no fact about which rule a speaker is following in using a linguistic expression. Now, if one urges that meaning something by a word is essentially a matter of following one rule rather than another, the sceptical argument leads to the radical sceptical conclusion (...) that there is no such thing as meaning anything by any word. According to the solution Kripke’s Wittgenstein proposes, we must instead concentrate on the ordinary practice of meaning-attribution, that is, on the conditions under which we can justifiably ascribe meaning to each other and the utility such a practice has in our life. Davidson has also argued that following rules is neither necessary nor sufficient for explaining success in the practice of meaning something by an utterance. According to his alternative view of meaning, a speaker’s success in this practice is fundamentally a matter of his utterance being successfully interpreted by an interpreter in the way the speaker intended. On the basis of these remarks, Davidson raises objections to Kripke’s Wittgenstein’s sceptical argument and solution. In this thesis, I will argue that Davidson has failed to fully grasp the essentially sceptical nature of the argument and solution proposed by Kripke’s Wittgenstein. I will argue that as a result of this Davidson’s objections and his alternative solution to Kripke’s Wittgenstein’s sceptical argument are mistaken. These criticisms are pursued via an investigation of Davidson’s problematic reading of Quine’s sceptical arguments for the thesis of the indeterminacy of translation. Having criticized Davidson’s actual response to Kripke’s Wittgenstein, I will claim that Davidson’s best option for resisting the sceptical problem is to adopt a form of non-reductionism about meaning. Claudine Verheggen’s recent claim that Davidson’s use of the notion of triangulation will help to establish non-reductionism will be argued to be a failure. I will urge that the main obstacle in defending a non-reductionist view is the problem of accounting for the nature of self-knowledge of meaning and understanding. After discussing Davidson’s account of self-knowledge and Crispin Wright’s objection to this account, I will argue that, although Wright’s objection is ultimately unsuccessful, Davidson’s account fails for other reasons. Finally, I tentatively suggest that the resources for an alternative response to the sceptical problem can possibly be extracted from Davidson’s account of intending, which has some features suggestive of a judgement-dependent account of meaning and intention.

Defending Robert Rosen’s claim that in every confrontation between physics and biology it is physics that has always had to give ground, it is shown that many of the most important advances in mathematics and physics over the last two centuries have followed from Schelling’s demand for a new physics that could make the emergence of life intelligible. Consequently, while reductionism prevails in biology, many biophysicists are resolutely anti-reductionist. This history is used to identify and defend a fragmented but (...) progressive tradition of anti-reductionist biomathematics. It is shown that the mathematicoephysico echemical morphology research program, the biosemiotics movement, and the relational biology of Rosen, although they have developed independently of each other, are built on and advance this antireductionist tradition of thought. It is suggested that understanding this history and its relationship to the broader history of post-Newtonian science could provide guidance for and justify both the integration of these strands and radically new work in post-reductionist biomathematics.

The possibility of a human head transplant poses unprecedented philosophical and neuroethical questions. Principal among them are the personal identity of the resultant individual, her metaphysical and social status: Who will she be and how should the “new” person be treated - morally, legally and socially - given that she incorporates characteristics of two distinct, previously unrelated individuals, and possess both old and new physical, psychological, and social experiences that would not have been available without the transplant? We contend that (...) this situation challenges linguistic conventions and conceptual binaries, and calls into question the major philosophical approaches to personal identity: animalism and reductionism. We examine these views critically vis-a-vis head transplantation and conclude that they fail to provide an adequate account of the identity of the resultant individual because both neglect the key role of embodiment for personal identity. We maintain that embodiment is central to personal identity and a radical alteration of the body will also radically alter that person, making her a different person. Consequently, a human head transplant will result in an individual partly continuous with the head/brain, and partly continuous with the body donor. We conclude that the resultant person would be different from both the individual whose head was transplanted and the one to whose body the “new” head is attached. (shrink)

An historically important conception of the unity of science is explanatory reductionism, according to which the unity of science is achieved by explaining all laws of science in terms of their connection to microphysical law. There is, however, a separate tradition that advocates the unity of science. According to that tradition, the unity of science consists of the coordination of diverse fields of science, none of which is taken to have privileged epistemic status. This alternate conception has roots in (...) Otto Neurath’s notion of unified science. In this paper, I develop a version of the coordination approach to unity that is inspired by Neurath’s views. The resulting conception of the unity of science achieves aims similar to those of explanatory reductionism, but does so in a radically different way. As a result, it is immune to the criticisms facing explanatory reductionism. This conception of unity is also importantly different from the view that science is disunified, and I conclude by demonstrating how it accords better with scientific practice than do conceptions of the disunity of science.

“Geneticization” is a term used to describe the ways in which the science of genetics is influencing society at large and medicine in particular; it has important implications for the process of diagnostics. Because genetic diagnostics produces knowledge about genetic disease and predisposition to disease, it is essentially influenced by these innovations in the disease concept. In this paper, I argue that genetic diagnostics presents new ethical challenges not because the diagnostic process or method in genetic diagnostics is ethically different (...) in kind from traditional medical diagnostics, but because it relies on a neo-ontological concept of disease in a context of genetic reductionism. Geneticization has not produced a radically new concept of disease, however, but has introduced innovations into the classical ontological concept of disease. When this new concept of disease is held in tandem with genetic reductionism, we are led to the absurd conclusion that disease is the very essence of the human being. I argue that neither the neo-ontological concept of disease nor genetic reductionism is necessary for a proper understanding of genetic diagnostics. (shrink)

Martin Gustafsson: Quine's Conception of Explication – and Why It Isn't Carnap's: This chapter clarifies Quine's conception of explication and identifies its place in his overall view of the aims and methods of philosophy. It does so by way of comparing his conception with Carnap's, Carnap being the philosopher from whom Quine got the notion of explication to begin with. In contravention of Quine's own suggestion, and against the view of some commentators, it is argued that Quine's and Carnap's conceptions (...) are importantly different, especially with regard to how explication can help us dissolve verbal philosophical confusions and disputes.

"A person is not explainable in molecular, field-theoretical, or physiological terms alone." With that declaration, Nobel laureate Gerald M. Edelman goes straight to the heart of Nature's Imagination, a vibrant and important collection of essays by some of the world's foremost scientists. Ever since the Enlightenment, the authors write, science has pursued reductionism: the idea that the whole can be understood by examining and explaining each of its parts. But as this book shows, scientists in every discipline are reaching (...) for a new paradigm that accounts for the whole--from the individual person to the universe itself. Nature's Imagination gathers together the work of thirteen leading mathematicians, astronomers, neuroscientists, and philosophers, as they discuss the revolution sweeping the sciences. Here Roger Penrose, Oliver Sacks, John Barrow, Gregory Chaitin, Maragret Boden, and others explore how and why classic reductionism is falling by the wayside in their own fields. As Freeman Dyson writes in the introduction, science is an art form, not a philosophical method, and it is always in search of new tools. Reductionism has done its work, and scientists are in search of another. Roger Penrose offers a fascinating account of irreducibility in mathematics, starting with the example of an impossible triangle--a drawing of a triangular object twisted so that could not exist in three dimensions. He breaks the triangle into three parts, showing that each corner is physically possible; only in combination is the triangle impossible. Both Penrose and mathematician Gregory Chaitin explore Godel's incompleteness theorem--as does John Barrow, who explains that Chaitin's proof of the theorem shows that, if we ever arrive at a Theory of Everything, there may be a still deeper and simpler unifying theory beyond that. Other contributors discuss the changing thinking in neuroscience, and the limitations of a mechanical view of the mind: as Oliver Sacks writes, "if we are to have a model or theory of mind as this actually occurs in living creatures in the world, it may have to be radically different from anything like a computational one." In addition, this volume includes staunch defenders of the classic scientific approach, such as Peter Atkins ("The omnicompetence of science, and in particular the simplicity its reductionist insight reveals, should be accepted as a working hypothesis until, if ever, it is proved inadequate"). The advance of science has been so startlingly swift in the last century that it has begun to approach limits never dreamed of before. This remarkable volume captures the latest thinking on where we must turn if we are to truly understand oursevles and the universe we live in. (shrink)

There are many ways of describing and explaining the properties of living systems; causal, functional, and reductive accounts are necessary but no one account has primacy. The history of biology as a discipline has given excessive authority to reductionism, which collapses higher level accounts, such as social or behavioural ones, into molecular ones. Such reductionism becomes crudely ideological when applied to the human condition, with its claims for genes everything from sexual orientation to compulsive shopping. The current enthusiasm (...) for genetics and ultra-Darwinist accounts, with their selfish-gene metaphors for living processes, misunderstand both the phenomena of development and the interactive role that DNA and the fluid genome play in the cellular orchestra. DNA is not a blueprint, and the four dimensions of life (three of space, one of time) cannot be read off from its one-dimensional strand. Both developmental and evolutionary processes are more than merely instructive or selective; the organism constructs itself, a process known as autopoiesis, through a lifeline trajectory. Because organisms are thermodynamically open systems, living processes are homeodynamic, not homeostatic. The self-organising membrane-bound and energy-utilising metabolic web of the cell must have evolved prior to so-called naked replicators. Evolution is constrained by physics, chemistry, and structure; not all change is powered by natural selection, and not all phenotypes are adaptive. Finally, therefore, living processes are radically indeterminate; like all other living organisms, but to an even greater degree, we make our own future, though in circumstances not of our own choosing.

The deontic status of tautologies and contradictions is one of the major puzzles for authors of early works on deontic logic. It is well-known that von Wright addresses this problem by adopting a Principle of Deontic Contingency, which says that tautologies are not necessarily obligatory and contradictions are not necessarily forbidden. A more radical solution is proposed by Anderson within a reductionist approach to deontic logic and consists in restricting the range of application of deontic modalities to contingent propositions. (...) Anderson’s solution has not received much attention in the literature, despite reflecting a typical feature of ordinary deontic reasoning, where non-contingent propositions are rarely, if ever, taken into account. In the present article we explore some of its formal consequences, providing a taxonomy of the properties of the Andersonian operators of obligation and permission for contingent propositions, O′ and P′, in the class of normal alethic systems.

Our philosophical understanding of mental illness is being shaped by neuroscience. However, it has the paradoxical effect of igniting two radically opposed groups of philosophical views. On one side, skepticism and denialism assume that, lacking clear biological mechanisms and etiologies for most mental illnesses, we should infer they are constructions best explained by means of social factors. This is strongly associated with medical nihilism: it considers psychiatry more harmful than benign. On the other side of the divide, naturalism and (...) class='Hi'>reductionism are on the look for failures in the biological functioning of the organism whenever a genuine mental illness occurs. Psychiatry as currently practiced, accordingly, exhibits the gaps of an ongoing research programme; a yet to be completed neuroscience would link mental illnesses with identifiable biological mechanisms. Both sides of this divide claim to be fostered by scientific discoveries and advances in neuroscience, when taken at face value. Against this background, we argue instead for a modest view. To that end, we draw attention to some nuances in the scientific realism debate. While contending that neuroscientific theories and models aim to provide true representations of their target systems, and can justifiably claim to have attained some, we argue that our confidence should not be placed beforehand in specific features of these scientific representations. Hence, it would be unwarranted to extract morals for psychiatry from posits (or their absence) in neuroscientific explanations of mental illnesses. To illustrate our position, we examine some recent discoveries in neuroscience concerning bipolar disorder. We conclude by linking our topic to a broader issue in the philosophy of medicine: insofar as psychiatry is a biomedical specialty, its classifications of health and disease are guided by pragmatic concerns, as well as by scientific discoveries.

The book offers a proposal on how to define truth in all its complexity, without reductionism, showing at the same time which questions a theory of truth has to answer and which questions, although related to truth, do not belong within the scope of such a theory. Just like any other theory, a theory of truth has its structure and limits. The semantic core of the position is that truth-ascriptions are pro-forms, i.e. natural language propositional variables. The book also (...) offers an explanation of the syntactic behaviour of truth-terms, and the pragmatic roles of truth-acts. The theory of truth we present is a technical proposal, relatively uncontaminated by radical philosophical discussion. It makes indeed philosophical points, but it is intended to be a conceptual analysis, as neutral as possible, of the aspects that may serve as a point of departure for more philosophically-laden destinations. Like the Fregean account of quantifiers, which is prior to and, to a large extent, independent of the metaphysical debate about existence and its forms, or the Kaplanian view on demonstratives, that is neutral regarding the debate about individuals and the possibilities we have to actually “reach” them in a referring act, we intend our proposal about truth to be a sophisticated and explicative setting that helps to situate other debates about truth accurately, far from the distorted and sometimes strongly ideological discussions that have turned the topic into a paradigm of philosophical impasse.

Enlightenment values are built around the presumption of an independent rational self, citizen, consumer and pursuer of self-interest. Even the authoritarian and communitarian variants of the Enlightenment presumed the existence of autonomous individuals, simply arguing for greater weight to be given to their collective interests. Since Hume, however, radical Enlightenment empiricists have called into question the existence of a discrete, persistent self. Today neuroscientific reductionism has contributed to the rejection of an essentialist model of personal identity. Contemporary transhumanism (...) has yet to grapple with the radical consequences of the erosion of liberal individualism on their projects of individually chosen enhancement and longevity. Most transhumanists still reflect an essentialist idea of personal identity, even as they embrace projects of radical cognitive enhancement that would change every constituent element of consciousness. Transhumanists need to grapple with how their projects and ethics would change if personal identity is an arbitrary, malleable fiction. (shrink)
