This chapter will argue that the criminal law is most compatible with a specific theory regarding the mind/body relationship: non-eliminative reductionism. Criminal responsibility rests upon mental causation: a defendant is found criminally responsible for an act where she possesses certain culpable mental states (mens rea under the law) that are causally related to criminal harm. If we assume the widely accepted position of ontological physicalism, which holds that only one sort of thing exists in the world – physical (...) stuff – non-eliminative reductive physicalism about the mind offers the most plausible account of the full-bodied mental causation criminal responsibility requires. Other theories of the mind/body relationship, including elminativism and non-reductive physicalism, threaten criminal responsibility because they do not offer satisfactory accounts of mental causation. Eliminativism, as the name implies, eliminates the mental or is skeptical that it can do the causal work necessary to responsibility; and non-reductive theories disconnect the mental from the physical/casual world such that the mental can no longer have reliable causal effects.

A physicalist view of qualia labelled non-eliminative reductionism is outlined. If it is true, qualia and physicalism can co-exist without difficulty. First, qualia present no particular problem for reductionist physicalism - they are entirely physical, can be studied and explained using the standard scientific approach, and present no problem any harder than any other scientists face. Second, reductionist physicalism presents no particular problem for qualia – they can be encompassed within an entirely physicalist position without any necessity, either (...) to reduce them to non-existence, or to treat them as new fundamental properties. It is suggested that the position also has sufficient explanatory power to successfully deal with the 'why like anything – why does experience exist at all' question and to counter both Chalmers' Conceivability Argument and Jackson's Knowledge Argument.

This paper addresses the following questions from the point of view of Nietzsche’s philosophy: What is the mind, and which kind of relationship does it hold to the body? Accordingly, the aim of this paper is to show that Nietzsche’s philosophy suggested a view of the mind that allows to outline an alternative stance to both mentalism and physicalism, as well as to both dualism and reductionism. It is argued that Nietzsche’s rehabilitation of the body as the specific seat (...) of the mind in opposition to the Cartesian supremacy of the Ego still is of a great interest for contemporary philosophy, since it is not equivalent either to a reversed form of Cartesian dualism or to a physicalist reductionism. It is argued that Nietzsche did restrict the concept of the mind but in order not to eliminate it, rather to “de-substantialise” it. As the body is described as “Leib-Organisation”, the mind becomes the course of various and manifold mental states that depend on a bodily basis. (shrink)

Francis Crick once remarked, "...the ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry" [1966:10]. Arguments to the contrary have been marshalled by many biologists and philosophers, notably Mayr [1986, 1988], and Rosenberg [1985]. Such arguments notwithstanding, reductionist hopes are still alive and well in both biological and philosophical circles. It seems reasonable to suppose that a first step in a reductionist programme would be the reduction or elimination (...) of non-biochemical, biological properties to biochemical properties. (shrink)

Feigl approaches philosophy of mind in the monist perspective of Logical Empiricism but he does not treat the mind-body problem in an eliminative manner. Although he modified his positions and wavered between strict reductionism and explicit non-reductionism, he never abandoned his conviction that the mind-body problem is not a pseudoproblem. Especially in his 'double-knowledge-view' he concedes private mental states that physical theory cannot account for and develops an identity theory that integrates two epistemic features - the way (...) of immediate experience and the indirect way of knowledge-by-description. Feigl's complex treatment of the mind-body problem retains its systematical importance even in the light of later developments in philosophy of mind. (shrink)

Two arguments are discussed which have been advanced in support of eliminative materialism: the argument from reductionism and the argument from functionalism. It is contended that neither of these arguments is effective if "non-scientific realism" is adopted with regard to commonsense propositional attitude psychology and its embedded notions. "Non-scientific realism," the position that commonsense propositional attitude psychology is an independently legitimate descriptive/explanatory framework, neither in competition with science nor vulnerable to being shown false by science, is defended.

Two of the best currently practising scholars of Ockham, Marilyn Adams and Paul Spade, seem to have accepted a reading of Ockham's ontological program which, although it contains much that is uncontroversially correct, attributes to Ockham a reductionist view that is on my interpretation of his works far too radical to be genuinely Ockham's. Their reading runs as follows. So far as entities go, Ockham accepts only particular substances and some particular qualities. Aristotle's categories, according to Ockham, are not 10 (...) broad classes of radically different sorts of things, but rather are classes of non-complex terms arranged roughly according to the kinds of questions they can be used to answer. When we look at these terms we find that those in the category of substance and some in the category of quality are not definable by some longer expression synonymous with them but simply signify each of the members of a certain class of substances or qualities. These terms are said to be absolute. But other terms can either be replaced by a definition that is synonymous with the term defined or can be interpreted as making “exponible” the sentences in which they occur. These terms are all said to be connotative. It is in principle possible to reword all the sentences in which these connotative terms appear so that the only categorematic terms left are absolute terms from the categories of substance and quality.

This is Part B of an article that defends non-eliminative structuralism about mathematics by means of a concrete case study: a theory of unlabeled graphs. Part A motivated an understanding of unlabeled graphs as structures sui generis and developed a corresponding axiomatic theory of unlabeled graphs. Part B turns to the philosophical interpretation and assessment of the theory: it points out how the theory avoids well-known problems concerning identity, objecthood, and reference that have been attributed to non-eliminative structuralism. (...) The part concludes by explaining how the theory relates to set theory, and what remains to be accomplished for non-eliminative structuralists. (shrink)

Part A summarizes the general attractions of non-eliminative structuralism.

As the theory demonstrates, graph theory can be developed consistently without eliminating unlabeled graphs in favour of sets; and the usual structuralist criterion of (...) identity can be applied successfully in graph-theoretic proofs. Part B will turn to the philosophical interpretation and assessment of the theory. (shrink)

Linnebo and Pettigrew have recently developed a version of non-eliminative mathematical structuralism based on Fregean abstraction principles. They recognize that this version of structuralism is vulnerable to the well-known problem of non-rigid structures. This paper offers a solution to the problem for this version of structuralism. The solution involves expanding the languages used to describe mathematical structures. We then argue that this solution is philosophically acceptable to those who endorse mathematical structuralism based on Fregean abstraction principles.

ABSTRACT To have a coherent picture of Wang Chong’s Lunheng is difficult. Some of Lunheng’s chapters obviously show Wang’s hostility to a large part of the folklore (including the social institutions based on it) and traditional philosophical texts. In some other chapters, however, Wang appears to be more sympathetic to the social institutions related to folk religious beliefs. Esther Sunkyung Klein & Colin Klein attempt to explain this prima facie inconsistency in terms of ‘piecemeal non-reductionism’, which roughly means that (...) Wang would take any testimonial belief for granted until he can find a defeater of such a belief. But this explanation merely depicts Wang as a defeater-seeker rather than a thinker looking for philosophical grounds of his claims in a more positive manner. In contrast, in this paper, I intend to attribute the following epistemological thesis to Wang: A testimonial belief taken from classics or folklore will be judged as unjustified if the knowledge attributor finds a non-negligible defeater of it, and such an attributor would feel more sympathetic to the target belief if it can be at least prima facie justified in the light of analogical reasoning.

How do we account for resemblance between concrete particular objects? What is it about reality which makes a sentence such as the following true? (1) x and y are both spherical Realists about properties claim that, at a fundamental level, this sentence is true because x and y both exemplify the property of sphericity. Michael Loux favours this account of resemblance. Nevertheless, Loux concedes that austere nominalism, which I understand to be the view that nothing exists over and above particular (...) concrete objects, can offer a plausible account of resemblance.

Mereological nihilism is the thesis that there are no composite objects—i.e. objects with proper material parts. One of the main advantages of mereological nihilism is that it allows its supporters to avoid a number of notorious philosophical puzzles. However, it seems to offer this advantage only at the expense of certain widespread and deeply entrenched beliefs. In particular, it is usually assumed that mereological nihilism entails eliminativism about ordinary objects—i.e. the counterintuitive thesis that there are no such things as tables, (...) apples, cats, and the like. In this paper, I argue that this assumption is false—mereological nihilists do not need to be eliminativists about tables, apples, or cats. Non-eliminativist nihilists claim that all it takes for there to be a cat is that there are simples arranged cat-wise. More specifically, non-eliminative nihilists argue that expressions such as ‘the cat’ in sentences such as ‘The cat is on the mat’ do not refer to composite objects but only to simples arranged cat-wise and compare this metaphysical discovery to the scientific discovery that ‘water’ refers to dihydrogen oxide. Non-eliminative nihilism, I argue, is not only a coherent position, but it is preferable to its more popular, eliminativist counterpart, as it enjoys the key benefits of nihilism without incurring the prohibitive costs of eliminativism. Moreover, unlike conciliatory strategies adopted by eliminative nihilists, non-eliminative nihilism allow its supporters to account not only for how we can assert something true by saying ‘The cat is on the mat’ but also for how we can believe something true by believing that the cat is on the mat.

It has recently been suggested that, for Leibniz, temporal facts globally supervene on causal facts, with the result that worlds differing with respect to their causal facts can be indiscernible with respect to their temporal facts. Such an interpretation is at variance with more traditional readings of Leibniz's causal theory of time, which hold that Leibniz reduces temporal facts to causal facts. In this article, I argue against the global supervenience construal of Leibniz's philosophy of time. On the view of (...) Leibniz defended here, he adopts a non-modal reduction of time to events, a form of reductionism that entails a strong covariation between a world's temporal facts and its causal facts. Consequently, worlds discernible with respect to their temporal facts must be discernible with respect to their causal facts, and worlds discernible with respect to their causal facts must be discernible with respect to their temporal facts. This position strongly favors the standard identificatory reduction of time to causation often imputed to Leibniz. (shrink)

The major Western monotheisms, and Christianity in particular, are often supposed to be committed to a substance dualism of a Cartesian sort. Aquinas, however, has an account of the soul which is non-Cartesian in character. He takes the soul to be something essentially immaterial or configurational but nonetheless realized in material components. In this paper, I argue that Aquinas’s account is coherent and philosophically interesting; in my view, it suggests not only that Cartesian dualism isn’t essential to Christianity but also (...) that the battle lines between dualism and materialism are misdrawn.

Gabriele Contessa has recently introduced and defended a view he calls ‘non-eliminative nihilism’. Non-eliminative nihilism is the conjunction of mereological nihilism and non-eliminativism about ordinary objects. Mereological nihilism is the thesis that composite objects do not exist, where something is a composite object just in case it has proper parts. Eliminativism about ordinary objects denies that ordinary objects exist. Eliminativism thus implies, for example, that there are no galaxies, planets, stars, ships, tables, books, organisms, cells, molecules, or atoms. (...) Non-eliminativism is the denial of eliminativism. Thus, NEN is the intriguing thesis that although composite objects do not exist, ordinary objects do. In this essay, I, first, summarize Contessa’s core support for NEN. Second, I describe two flaws in that support when it comes to organismic terms. Third, I consider and reject two possible responses on behalf of NEN’s defenders. Fourth, I show how the flaws cast doubt upon NEN itself. Finally, I offer reasons to think that if nihilism is true, then the folk have probably been trying to fix the reference of organismic terms to apparent objects within illusions. (shrink)

The number of positions identified with structural realism in philosophical debates about scientific knowledge has grown significantly in the past decade, particularly with respect to the metaphysical or ‘ontic’ approach (OSR). In recent years, several advocates of OSR have proposed a novel understanding of it in order to side-step a serious challenge faced by its original formulation, eliminative OSR. I examine the conceptual basis of the new, noneliminative view, and conclude that it too faces a serious challenge, resulting in (...) a dilemma for ontic structuralists regarding the ontological status of objects and properties, and the relative “ontological priority” of these entities with respect to the relations in which they stand.

Martha Nussbaum proposes a universal list of human capabilities as the basis for fundamental political principles. She claims that the list, in an Aristotelian spirit, might be justified by an ongoing inquiry into valuable human functionings for the good life. Here I argue that the attractiveness of Nussbaum’s theory crucially depends on the philosophical possibility of a non-reductionist understanding of naturalism and on resolving the tensions between ethical and political aspects of the role of capabilities. Through a comparison of Nussbaum’s (...) approach with those of Aristotle and (less familiarly) Hume, I try to show that in these alternative versions we find valuable resources for the kind of non-reductionist model which might, in line with Nussbaum’s own objectives, provide the basis for a capabilities-based critique of dominant modes of normative theorizing and their influence in public discourse.

This commentary focuses on three aspects of Sandro Nannini’s paper Time and Consciusness in Cognitive Naturalism: the parallel between Einstein’s theory of relativity and the new science of the mind/brain; the Cartesian characterization of non-reductionist positions in the philosophy of mind; the alleged illusory status of consciousness, free will and the Self. We suggest, first, that Nannini overstates the success of cognitive neuroscience; second, that non-reductionism is not necessarily a Cartesian position; and third, that the neurocognitive science data do (...) not show or even suggest, that consciousness, free will and the Self are illusory phenomena.

In this paper I argue that, according to a particular physicalist conception of information, information is both alethically neutral or non-alethic, and is intrinsically semantic. The conception of information presented is physicalist and reductionist, and is contrary to most current pluralist and non-reductionist philosophical opinion about the nature of information. The ontology assumed for this conception of information is based upon physicalist non-eliminative ontic structural realism. However, the argument of primary interest is that information so construed is intrinsically semantic (...) on a reductionist and non-alethic basis where semantic content is constituted by indication along causal pathways. Similar arguments have been presented by philosophers with respect to representation. I suggest the conception of information that I present is correct by the lights of the best applied mathematical and scientific theories of information. If so, there is no need for any separate theory of semantic information. Thus I present a theory of intrinsically semantic information which also constitutes an informational theory of truth where truth reduces to information. In the last section I discuss weakly and strongly semantic information, and reject them in favour of alethically neutral intrinsically semantic information. (shrink)

Hypersequent calculi can formalize various non-classical logics. In [9] we presented a non-commutative variant of HC for the weakest temporal logic of linear frames Kt4.3 and some its extensions for dense and serial flow of time. The system was proved to be cut-free HC formalization of respective temporal logics by means of Schütte/Hintikka-style semantical argument using models built from saturated hypersequents. In this paper we present a variant of this calculus for Kt4.3 with a constructive syntactical proof of cut elimination.

Genera connections between quantifier elimination and decidability for first order theories are studied and exemplified.

The so-called 'Extreme Claim' asserts that reductionism about personal identity leaves each of us with no reason to be specially concerned about his or her own future. Both advocates and opponents of the Extreme Claim, whether of a reductionist or non-reductionist stripe, accept that similar problems do not arise for non-reductionism. In this paper I challenge this widely held assumption.

According to Wimsatt, a proper treatment of reduction must distinguish between two types of reductionist activities scientists engage in. One of the benefits of better understanding the nature of reduction, he believes, is that it shows that eliminativism, that is, the elimination of concepts and theories from science, is a rather circumscribed and limited affair, especially in the case of inter-level reductionist activities. While I agree with Wimsatt that it is important to distinguish the two types of reductionisms, I show (...) that elimination in inter-level reductionist activities can be a powerful heuristic in science, driving both inter-level and successional reduction.

Almost everyone agrees that many testimonial beliefs constitute knowledge. According to non-reductionists, some testimonial beliefs possess positive epistemic status independent of that conferred by perception, memory, and induction. Recently, Jennifer Lackey has provided a counterexample to a popular version of this view. Here I argue that her counterexample fails.

This paper investigates the seeming incompatibility of reductionism and non-reductionism in the context of complexity sciences. I review algorithmic information theory for this purpose. I offer two physical metaphors to form a better understanding of algorithmic complexity, and I briefly discuss its advantages, shortcomings and applications. Then, I revisit the non-reductionist approaches in philosophy of mind which are often arguments from ignorance to counter physicalism. A new approach called mild non-reductionism is proposed which reconciliates the necessities of (...) acknowledging irreducibility found in complex systems, and maintaining physicalism. (shrink)

While increasing numbers of philosophers have argued for eliminating the retributivist elements of criminal justice systems, their arguments often fall short due to internal inconsistency. Some of the best known of these arguments — such as those provided by Derk Pereboom and Gregg Caruso — rely on the claim that there are moral grounds for rejecting retributivism. In defending this claim, these philosophers typically provide arguments seeking to undermine the type of agent responsibility that they believe is needed to justify (...) retributivism. This is usually followed by an assertion that since the excessive suffering caused by retributivist punishment cannot be justified, it is therefore immoral to preserve remnants of it in our criminal justice systems. This paper — which opposes the moral case against retributivism provided by Pereboom and Caruso, and favors non-moral reasons that recommend rejecting a retributivist approach — is divided into three parts. In part one, I discuss why Pereboom and Caruso are correct in thinking that free will skepticism undercuts the moral justification for retributivism. Part two sets out to explain why their moral case against retributivism fails insofar as it runs afoul of the folk intuitions that are called upon to defend Pereboom’s account of free will skepticism. In part three, I provide a non-moral case against the retributivism that is founded on considerations of self-interest and empathy. (shrink)

Descriptive accounts of the nature of explanation in neuroscience and the global goals of such explanation have recently proliferated in the philosophy of neuroscience and with them new understandings of the experimental practices of neuroscientists have emerged. In this paper, I consider two models of such practices; one that takes them to be reductive; another that takes them to be integrative. I investigate those areas of the neuroscience of learning and memory from which the examples used to substantiate these models (...) are culled, and argue that the multiplicity of experimental protocols used in these research areas presents specific challenges for both models. In my view, these challenges have been overlooked largely because philosophers have hitherto failed to pay sufficient attention to fundamental features of experimental practice. I demonstrate that when we do pay attention to such features, evidence for reduction and integrative unity in neuroscience is simply not borne out. I end by suggesting some new directions for the philosophy of neuroscience that pertain to taking a closer look at the nature of neuroscientific experiments. (shrink)

I argue that there is a tension between three popular views in the philosophy of mind: (1) mental properties are not identical with physical properties (a version of nonreductionism), but (2) mental properties are had solely by virtue of physical properties (physicalism regarding the mind), which requires that (3) mental properties supervene on physical properties. To earn the title "physicalist," one must hold a sufficiently strong version of the supervenience thesis. But this, I argue, will be a version that undermines (...) nonreductionism. (shrink)

Elimination of quantifiers is shown to fail dramatically for a group of well‐known mathematical theories (classically enjoying the property) against a wide range of relevant logical backgrounds. Furthermore, it is suggested that only by moving to more extensional underlying logics can we get the property back.

1 Non-reductive physicalists deny that there is any explanation of mentality in purely physical terms, but do not deny that the mental is entirely determined by and constituted out of underlying physical structures. There are important issues about the stability of such a view which teeters on the edge of explanatory reductionism on the one side and dualism on the other (see Kim 1998). 2 Save perhaps for eliminative materialism (see Churchland 1981 for a classic exposition). In fact, (...) however, while. (shrink)

The Non-Reductionist holds that personal identity is a matter in whole or in part of “further facts,” facts over and above those about psychological and physical continuity and connectedness. If Non-Reductionism is true, then it is possible for there to be “nonsymmetrical fission cases” in which there is nonsymmetry with respect to further facts such that the fissioner is identical with one of the fission products but not the other, even though there is symmetry along each branch with respect (...) to non-further facts. If it is also true that the fissioner gets what matters with respect to the fission product to which the fissioner is not identical in those cases, it is possible for identity and what matters to come apart. If the Non-Reductionist is to hold fast to the importance of identity, she must demonstrate that the fissioner does not get what matters in survival with respect to the fission product to which he is not identical in cases of nonsymmetrical fission. One way to get this result would be to demonstrate that Non-Reductionism in and of itself has the implication that the fissioner does not get what matters with respect to the fission product to which he is not identical in the nonsymmetrical fission case. Parfit offers an argument that is meant to show that the Non-Reductionism qua Non-Reductionism has just this result. I outline Parfit’s argument and suggest that it does not work. (shrink)

In this paper, I argue that anti-reductionist moral realism still has trouble explaining supervenience. My main target here will be Russ Shafer-Landau's attempt to explain the supervenience of the moral on the natural in terms of the constitution of moral property instantiations by natural property instantiations. First, though, I discuss a recent challenge to the very idea of using supervenience as a dialectical weapon posed by Nicholas Sturgeon. With a suitably formulated supervenience thesis in hand, I try to show how (...) Shafer-Landau's proffered strategy to explain supervenience not only fails to explain supervenience, but that it also has a number of implausible consequences. The more general lesson is that strategies which may work well for explaining supervenience in the philosophy of mind and other areas cannot be assumed to carry over successfully to the metaethical context. We should therefore treat so-called `companions in guilt' arguments in this area of philosophy with considerable skepticism. Key Words: expressivism • moral realism • non-naturalism • reductionism • supervenience • trope. (shrink)

We study cut-elimination in first-order classical logic. We construct a sequence of polynomial-length proofs having a non-elementary number of different cut-free normal forms. These normal forms are different in a strong sense: they not only represent different Herbrand-disjunctions but also differ in their propositional structure. This result illustrates that the constructive content of a proof in classical logic is not uniquely determined but rather depends on the chosen method for extracting it.

Free agency can be explained causally if the causal approach does not imply reductionism. A non-reductionist account of action is possible along the lines of Davidsonian 'anomalous monism'. Mental events, i.e. prepositional attitudes activated by indexical beliefs, are the causes of actions. Free agency presupposes a special type of causes to be analysed as rational causes allowing human agents to be self-determinant, autonomous agents in Kantian terms. An action is free if it has rational causes not to be ruled (...) out by natural causes. With causes of actions being activated prepositional attitudes their rationality is analysed in terms of the coherence of prepositional attitudes. Principles of rational choice are not the basic ingredients of free i.e. rational action but have to conform to the prepositional attitudes of the human agent. (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)

The major tendency within the discipline of political science has been to try to achieve a science modeled on the natural sciences and mathematics, following the pattern of other social sciences. This tendency has led to many reductionistic efforts to explain political behavior in terms of one or more functions, such as power, linguistic, psychical, or the economic. The institutional community of government and citizens—the political community or state—is thus overlooked or reduced to one or more functions. In critique of (...) this tendency, this paper shows how the work on entities and functions by the Dutch legal philosopher Herman Dooyeweerd illumines the errors of reductionism and points the way to a multi-functional entity science of the political community.

An (n, k)-ary quantifier is a generalized logical connective, binding k variables and connecting n formulas. Canonical systems with (n, k)-ary quantifiers form a natural class of Gentzen-type systems which in addition to the standard axioms and structural rules have only logical rules in which exactly one occurrence of a quantifier is introduced. The semantics for these systems is provided using two-valued non-deterministic matrices, a generalization of the classical matrix. In this paper we use a constructive syntactic criterion of coherence (...) to characterize strong cutelimination in such systems. We show that the following properties of a canonical system G with arbitrary (n, k)-ary quantifiers are equivalent: (i) G is coherent, (ii) G admits strong cut-elimination, and (iii) G has a strongly characteristic two-valued generalized non-deterministic matrix. In addition, we define simple calculi, an important subclass of canonical calculi, for which coherence is equivalent to the weaker, standard cut-elimination property. (shrink)

RésuméJe soutiendrai que la façon dont Davidson rend compte de l'intention pure peut être comprise comme une analyse de l'intention comme étant relative à un jugement dans une perspective en première personne. Selon Davidson, avoir la pure intention de faire A, c'est formuler un jugement tout bien considéré qu'il est désirable de faire A. Dans cette analyse anti-réductionniste, l'intention est traitée comme un état irréductible du sujet. J’établirai une comparaison entre cette analyse et celle de Wright et je montrerai comment (...) la position de Davidson peut être considérée comme une analyse non-réductionniste rapportant l'intention au jugement, selon les directions suggérées par Wright.
