Imagine slicing your hand with a steak knife. Inevitably, this leads to a characteristic unpleasant sensation, and just as reliably, to a withdrawal of the wounded limb. But can this rather mundane fact--and other similar facts--shed any light on the mind-body problem or the issue of the role of experience in causing behavior? In my dissertation, I explore this issue head on, and in the process clarify and criticize the arguments of philosophers who have given an affirmative answer to this (...) question--philosophers such as William James and Herbert Spencer. These arguments have coupled evidence like the above with the fact that human beings have evolved, in order to make the case that epiphenomenalism with respect to qualia is false. My first task will be to formulate a rigorous version of a James-Spencer style argument, which will occupy us in Chapter 1. Chapter 2 is dedicated to answering a number of objections to the argument, in an effort to show that if there is a problem with it, this problem lies elsewhere. Chapter 3 explores alternative arguments in the spirit of the original one formulated in Chapter 1, and discusses any resulting effects on the plausibility of the conclusion. Chapter 4 is the capstone chapter of the dissertation. In it, I discuss a crucial objection to all arguments in the spirit of that given in the first chapter--namely, that physicalism has analogous flaws to epiphenomenalism where accommodating the relevant evidence is concerned. My conclusions in this final chapter are twofold. First, that even if there is no fatal flaw in the general strategy the evolutionary argument employs, it works against all forms of dualism, not just epiphenomenalism. And second, the accusations made in the objection are correct; physicalism suffers from problems analogous to those faced by epiphenomenalism. Although the primary findings of the dissertation are negative, there are many lessons we can take from them along the way. Most prominent among them is an improved perspective on the appropriate roles of empirical findings and armchair philosophical theorizing in debate over the mind-body problem. (shrink)

Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straightforward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception (...) deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indiscriminability Principle, the claim that two experiences that are introspectively indiscriminable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND. Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too. I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world.

In this thesis, I argue that physicalism should be understood to be the view that mental properties are realized by physical properties. In doing this, I explore what the realization relation might be. Since realization is the relation that should help us formulate physicalism, I suggest that the theoretical role of realization consists in explaining some of the things that physicalists wish to explain. These are: How are mental properties metaphysically necessitated by physical properties? How are mental properties causally efficacious? (...) A theory of realization should provide resources for answering these questions. Having identified the theoretical role of realization, I discuss several theories of realization, but then focus on the subset view of realization. According to the subset view, a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P. I argue that the realization relation as it is formulated by the subset view is a promising candidate to play the theoretical role that I want realization to play. I then investigate how this theoretical role is occupied. In doing so, I provide a general metaphysical framework that the defenders of the subset view can appeal to. This framework specifies in what ways properties are related to their causal powers. Discussing some problems that the subset view faces, I propose my own version of the subset view. I argue that a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P, and P is more fundamental than Q. Thanks to the requirement that a realized property is less fundamental than its realizers, two things that the original version of the subset view cannot explain are guaranteed: first, fundamental properties are not realized; second, arbitrary conjunctions of properties do not realize their conjuncts. By showing how a theory of realization can help us explain some of the things that physicalists typically wish to explain, I also show that a non-reductive variety of physicalism does not face the problems that it is commonly thought to face.

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.

The Aristotelian Society’s Virtual Issue is a free, online publication, made publically available on the Aristotelian Society website. Each volume is theme-based, collecting together papers from the archives of the Proceedings of the Aristotelian Society and the Proceedings of the Aristotelian Society Supplementary Volume that address the chosen theme. This year's Virtual Issue includes a selection of papers from across the Society’s fourteen decades, each accompanied by a specially commissioned present-day response. The aim of the volume is to aid reflection (...) on how to go about doing moral and political philosophy, by bringing together papers that bear on their epistemology and methodology. In some cases this involves pieces whose declared focus is on one of those areas, as is the case with Margaret MacDonald’s 1941 essay ‘The Language of Political Theory’ and Mary Midgley’s 1974 article ‘The Neutrality of the Moral Philosopher’. In other cases the editor, Ben Colburn, selected papers whose primary focus is elsewhere, but which include some interesting epistemological or methodological reflections or implications along the way. The contributions from our present-day commentators vary similarly in how far their explicit attention is methodological. Nevertheless, there is throughout a concern on how to ‘be an honest reasoner’, to borrow a phrase from the late Dudley Knowles. (shrink)

La finalidad de este artículo es mostrar la originalidad de la categoría lógica de "historicidad" propuesta por Max Weber, sugiriendo que en sus obras sobre la metodología de las ciencias histórico-sociales se puede encontrar una estimulante y precursora contribución al análisis de algunos problemas lógicos y formales referentes a la relación entre el conocimiento humano y el caos de la realidad (lo que podríamos llamar, ante litteram, "ciencia del caos"). Particularmente, considerando que en Weber el conocimiento científico no encuentra en (...) el mundo natural "hechos" a los cuales agarrarse sino un caos de acontecimientos únicos e infinitamente divisibles, el análisis se concentra en los siguientes aspectos: (a) la separación de la imputación causal de la noción de una ley (natural) necesaria; (b) la importancia atribuida a los "juicios de probabilidad" con diferentes grados de certeza; (c) la irreductibilidad de los acontecimientos individuales a modelos, leyes y tipos-(ideales) científicos; (d) los efectos asociados a la diferenciación del punto de vista de un observador científico. This paper aims at revealing the originality of Max Weber's conception of the logical category of "historicity", suggesting that in his writings on the methodology of the social sciences we can find a stimulating and forerunner contribution to the analysis of some logical and formal problems concerning the relationship between human knowledge and the chaos of reality (what we might call, antelitteram, "science of chaos"). In particular, considering that in Weber's conception scientific knowledge finds no facts "to grasp" in the natural world, but rather a chaos ofunique and infinitely divisible events, the analysis will be focused on the following aspects: (a) Weber's separation of causal imputation from the notion of necessary (natural) law; (b) the importance attached to "probability judgments" with different degrees of certainty; (c) the proclaimed irreducibility of individual events to scientific models, laws, and (ideal)-types; (d) the effects imputed to the differentiation of the point of view of a scientific observer.

Interactive dualism is notorious for supporting genuine and autonomous mental causation that is allegedly impossible for its confliction with basic principles of physics. The purpose of this essay is to show the invalidity of this commonplace view, by arguing to the contrary in three different steps. First, I will deal with the objection about the non-scientific character of interactive dualism, as it is conceived of in present-day philosophy of mind. Second, I will illustrate and critically examine three contemporary models of (...) dualistically understood mental causation. Finally, I will summarise the chief assumptions made in these models and try to lay down my own proposal. (shrink)

I defend a dualist model of psychophysical causal relevance, according to which mental events are not causes in the physical domain, but are causally relevant in this domain because they enable — or, in other words, provide the appropriate structure for — physical events to be caused. More specifically, I defend the claim that mental events are ‘double preventers’ within the physical domain, where double preventers are a type of enabling event. The distinction that I make between causes and enabling (...) events and the dualist model of psychophysical causal relevance that I defend has emerged from my acceptance of the powers theory of causation. In this paper, I explore how this dualist model of psychophysical causal relevance offers a response to Papineau’s defence of the causal completeness principle via the conservation laws. (shrink)

According to the standard view, the causal process connecting a past representation and its subsequent recall involves intermediary memory traces. Yet Bertrand Russell and Ludwig Wittgenstein held that since the physiological evidence for memory traces isn't quite conclusive, it is prudent to come up with an account of memory causation-referred to as nmemic causation—that manages without the stipulation of memory traces. Given mnemic causation, a past representation is directly causally active over a temporal distance. I argue that the stipulation of (...) memory traces is indeed indispensable for analyzing mernory causation. (shrink)

Roger W. Sperry received the Nobel Prize for Physiology in 1981 for his outstanding scientific achievements in connection with the study of people with severed brain commissures. Sperry linked the results of his research to philosophical considerations pertaining to the conscious mind of human beings and its place in the natural sciences. He was interested in the philosophical question of whether or not the severing of the cerebral hemispheres constituted a violation of the unity of consciousness. Sperry’s explanatory account of (...) mind-body interaction forms part of a broadly construed theory of emergent interactionism – one that also purports to guarantee the unity of consciousness. In this article, I first present an intellectual profile of Sperry, outlining the evolution of his philosophical-scientific analyses. I then outline the emergence and flourishing of theories of emergence, along with the elements essentially associated with them. Using this as a basis, I go on to consider Sperry’s account of emergent interaction more closely, focusing on his understanding of downward causation. In conclusion, I show how his theory corresponds to a version of emergent interactionism, and seek to address some criticisms leveled against it. I also aim to establish how far this theory can be said to answer the question of the conscious character of mental states. (shrink)

The notion of emergence has accompanied philosophy of science since the late XIX century, claiming that in some systems there are properties in certain levels that cannot be deduced from properties of their components as seen in more fundamental levels. Throughout the XX century, emergence has been characterized by four pillars: unpredictability, novelty, restriction and downward causation. These four pillars have been related to the assumption of a hierarchical order of reality in different levels of organization. In this paper, we (...) show that it is possible to explain the nature of the emergent properties through the nearly-decomposability criterion introduced by Herbert Simon. (shrink)

Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

Models of memory in cognitive science and philosophy have traditionally explained human remembering in terms of storage and retrieval. This tendency has been entrenched by reliance on computationalist explanations over the course of the twentieth century; even research programs that eschew computationalism in name, or attempt the revision of traditional models, demonstrate tacit commitment to computationalist assumptions. It is assumed that memory must be stored by means of an isomorphic trace, that memory processes must divide into conceptually distinct systems and (...) phases, and that human remembering consists in inner, cognitive processes that are implemented by distinct neural processes. This dissertation draws on recent empirical work, and on philosophical arguments from Ludwig Wittgenstein and others, to demonstrate that this latent computationalism in the study of memory is problematic, and that it can and should be eliminated. Cognitive psychologists studying memory have encountered numerous data in recent decades that belie archival models. In cognitive neuroscience, establishing the neural basis of storage and retrieval processes has proven elusive. A number of revised models on offer in memory science, that have taken these issues into account, fail to sufficiently extricate the archival framework. Several impasses in memory science are products of these underlying computationalist assumptions. Wittgenstein and other philosophers offer a number of arguments against the need for, and the efficacy of, the storage and retrieval of traces in human remembering. A study of these arguments clarifies the ways that these computationalist assumptions are presently impeding the science of memory, and provides ways forward in removing them. We can and should characterize and model human memory without invoking the storage and retrieval of traces. A range of work in connectionism, dynamical systems theory, and recent philosophical accounts of memory demonstrate how the science of memory can proceed without these assumptions, toward non-archival models of remembering.

At the start of the 20th century the question of whether life could be explained in purely me- chanical terms was as hotly debated as the mind-body problem is today. Two factions opposed each other: Biological mechanists claimed that the properties characteristic of living organisms could be ex- plained mechanistically, in the way the behavior of a clock can be explained by the properties and the arrangement of its cogs, springs, and weights. Substantial vitalists, on the other hand, maintained that (...) the explanation envisaged by the mechanists was impossible and that one had to postulate a special nonphysical substance in order to explain life.

The term emergence, or irreducibility, has been used in a great variety of senses over the years, and different senses are useful in different discursive contexts. In this paper the focus is on one specific context, that of methodologically oriented social theory, and the question to answer is, what might be the most useful sense of emergent irreducibility in that field? To answer that question, key intuitions of emergence are first abstracted from the concept’s history. Three main senses of the (...) term are distinguished based on those different intuitions. Then the likely linguistic functions of emergence in each of those main senses are gauged in social theory and methodology. It is argued that one of the senses – here called “contingently epistemological irreducibility” – is in fact more useful as regards social scientific methodology than the others. (shrink)

While most near-death researchers have disregarded reports of near-death experiences (NDEs) with hallucinatory features, many have sought cases of veridical paranormal perception during NDEs. But despite more than a quarter-century of near-death studies, no compelling evidence that NDErs can obtain information from remote locations during their NDEs has been forthcoming. This paper, Part I of a critique of survivalist interpretations of NDEs, reviews the quality of the evidence for veridical observations during NDEs, and finds the case for veridical paranormal perception (...) during NDEs wanting.
