Ingvar Johansson has argued that there are not only determinate universals, but also determinable ones. I here argue that this view is misguided by reviving a line of argument to the following effect: what makes determinates falling under a same determinable similar cannot be distinct from what makes them different. If true, some similarities — imperfect similarities between simple determinate properties — are not grounded in any kind of property-sharing. I suggest that determinables are better understood as maximal disjunctions of (...) brutely and imperfectly similar determinates. Such brute similarities have been thought to clash with realism about universals. I argue that this worry stems from the mistaken assumption that perfect and imperfect similarities are relations of a same kind. If exact and inexact resemblances are distinct and heterogeneous explananda, the realist about universals might explain the first thanks to property-sharing, while happily leaving imperfect similarities between properties unexplained.

Stephen Yablo offers a solution to the problem of mental causation by claiming that the physical is a determinate of the mental's determinable, and therefore the mental and physical do not compete for causal relevance. I present Yablo's solution and argue that the mental‐physical relation cannot meet three necessary conditions for determination. That relation fails to meet the requirements that determinates of the same determinable be incompatible and that no property can be a determinate of more than one determinable. Further, (...) the mental and physical do not fall under the same series of scope inclusions as determinables and their determinates must. Yablo's conception of determination might be rendered more general to avoid these objections, but doing so would prevent it from functioning as a competitor to extant theories of the mental‐physical relation. Thus, Yablo's solution to the problem of mental causation cannot be both adequately specific and correct. (shrink)

Do determinable properties such as colour, mass, and height exist in addition to their corresponding determinates, being red, having a mass of 1 kilogram, and having a height of 2 metres? Optimists say yes, pessimists say no. Among the latter are Carl Gillett and Bradley Rives who argue that optimism leads to systematic overdetermination of causal powers and hence should be rejected on the grounds that the position is ontologically unparsimonious. In this paper I defend optimism against this charge by (...) showing that overdetermination of causal powers cannot plausibly be avoided when grounding what I call joint powers. It is therefore not clear why the optimist should be worried about the overdetermination of causal powers that follows from positing determinable properties. (shrink)

“Realization” is a technical term that is used by metaphysicians, philosophers of mind, and philosophers of science to denote some dependence relation that is thought to obtain between higher-level properties and lower-level properties. It is said that mental properties are realized by physical properties; functional and computational properties are realized by first-order properties that occupy certain causal/functional roles; dispositional properties are realized by categorical properties; so on and so forth. Given this wide usage of the term “realization”, it would be (...) right to think that there might be different dependence relations that this term denotes in different cases. Any relation that is aptly picked out by this term can be taken to be a realization relation. The aim of this state-of-the-field article is to introduce the central questions about the concept of realization, and provide formulations of a number of realization relations. In doing so, I identify some theoretical roles realization relations should play, and discuss some theories of realization in relation to these theoretical roles. (shrink)

In recent years, the debate on the problem of causal exclusion has seen an ‘interventionist turn’. Numerous non-reductive physicalists (e.g. Shapiro and Sober 2007) have argued that Woodward's (2003) interventionist theory of causation provides a means to empirically establish the existence of non-reducible mental-to-physical causation. By contrast, Baumgartner (2010) has presented an interventionist exclusion argument showing that interventionism is in fact incompatible with non-reductive physicalism. In response, a number of revised versions of interventionism have been suggested that are compatible with (...) non-reductive physicalism. The first part of this paper reconstructs the definitional details of these modified interventionist theories. The second part investigates whether the modification proposed in Woodward (2011) is not only compatible with, but moreover supports non-reductive physicalism. In particular, it is examined whether that newest variant of interventionism allows for empirically resolving the problem of causal exclusion as envisaged by Shapiro, Sober and others. (shrink)

This paper presents the view that tropes can change, and so are not individuated by their determinate qualitative characters. On the view I have in mind, a trope is at any given time fully determinate, but can change qualitatively within the bounds set by a determinable essence. A charge trope, for example, must at any time have some exact intensity, but can survive changes in intensity. My argument, roughly, is this: Objects can change, and tropes are the parts of objects (...) that change (in a special sense of ‘part’), so tropes can change too. After some preliminaries, I present the argument carefully and discuss the operant notions. I then discuss each premise in turn. I respond to the charge that the view isn't realist, and to objections based on identity‐conditions for tropes. I describe both substratum‐ and bundle‐theoretic versions of the view, and finally, show what the view buys us. (shrink)

ABSTRACT: A popular strategylor resolving Kim 's exclusion problem is to suggest that mental and physical property tropes are identical despite the non-identity of the mental and physical properties themselves. I argue that mental and physical tropes can be identified without losing the dispositional character of mentality only if a dual-character hypothesis regarding the intrinsic characters of tropes is endorsed. But even with this assumption, the causaI efficacy of the wrong dispositions is secured.RÉSUMÉ: On résout habituellement le problème de l'exclusion (...) de Kim en suggérant que les tropes de propriété mentale et physique sont identiques en dépit de la non-identité des propriétés mentales et physiques elles-mêmes. Je soutiens que les tropes mentaux et physiques peuvent être ramenés l'un à l'autre sans perdre le caractère dispositionnel de la pensée, à la condition d'approuver une hypothèse sur la nature double des caractères intrinsèques des tropes. Même en suivant cette proposition, l'efficacité causale des dispositions fausses est maintenue. (shrink)

According to the subset view of realization, a property realizes another if the causal powers of the latter are a subset of those of the former. Against this view, some authors (in particular, Kevin Morris and Paul Audi) have argued that it has an untenable consequence that realizing properties are less fundamental than the properties they realize, because the subset view characterizes realized properties as parts (subsets) of their realizers whereas it is generally true that a part is prior to (...) its whole. This paper defends the subset view from this “part-whole” objection, by arguing that if we compare individual powers of realizer and realizee with particular attention to their manifestation conditions, it turns out that each power of a realizee is grounded in some power of its realizer. This grounding relation between powers, I shall argue, allows subset theorists to explain why a realizer is more fundamental than its realizee, even while having the latter as a part. (shrink)

There is a familiar tension between the two main components of non-reductive physicalism, which are physicalism, on the one hand, and the non-reducibility or autonomy of so-called special sciences (i.e., sciences other than physics), on the other. While it is often claimed that this tension can be satisfactorily resolved by adopting the subset account of realization (defended by e.g., Shoemaker (2001) and Wilson (2011)), this paper challenges that popular view, by elaborating some critical comments by Funkhouser (2014). Then, after examining (...) Funkhouser’s own position, this paper proposes a new way of resolving the aforementioned tension, which consists in refining the subset account’s analysis of realization on the basis of various dependence relations between causal powers.

Worries about mental causation are prominent in contemporary discussions of the mind and human agency. Originally, the problem of mental causation was that of understanding how a mental substance (thought to be immaterial) could interact with a material substance, a body. Most philosophers nowadays repudiate immaterial minds, but the problem of mental causation has not gone away. Instead, focus has shifted to mental properties. How could mental properties be causally relevant to bodily behavior? How could something mental qua mental cause (...) what it does? After looking at the traditional Problem of Interaction, we survey various versions of the property-based problem and look at proposed solutions to them. (shrink)

I argue that the present (if not insuperable) lack of fixed standards in philosophy is associated with three barriers to philosophical progress, pertaining to intra-disciplinary siloing, sociological rather than philosophical determinants of philosophical attention, and the encouraging of bias.

[This is a paper that was originally written in 2017 and doesn't represent Silva's current thinking about degrees of confidence, conviction, and rationality.] Can there be knowledge and rational belief in the absence of a rational degree of confidence? Yes, and cases of "mistuned knowledge" demonstrate this. In this paper we leverage this normative possibility in support of advancing our understanding of the metaphysical relation between belief and credence. It is generally assumed that a Lockean metaphysics of belief that reduces (...) outright belief to degrees of confidence would immediately effect a unification of coarse-grained epistemology of belief with fine-grained epistemology of confidence. Scott Sturgeon has suggested that the unification is effected by understanding the relation between outright belief and confidence as an instance of the determinable-determinate relation. But determination of belief by confidence would not by itself yield the result that norms for confidence carry over to norms for outright belief unless belief and high confidence are token identical. We argue that this token-identity thesis is incompatible with the neglected phenomenon of “mistuned knowledge”—knowledge and rational belief in the absence of rational confidence. We contend that there are genuine cases of mistuned knowledge and that, therefore, epistemological unification must forego token identity of belief and high confidence. We show how partial epistemological unification can be secured given determination of outright belief by degrees of confidence even without token-identity. Finally, we suggest a direction for the pursuit of thoroughgoing epistemological unification. (shrink)

I argue that an adequate account of non-reductive realization must guarantee satisfaction of a certain condition on the token causal powers associated with (instances of) realized and realizing entities---namely, what I call the 'Subset Condition on Causal Powers' (first introduced in Wilson 1999). In terms of states, the condition requires that the token powers had by a realized state on a given occasion be a proper subset of the token powers had by the state that realizes it on that occasion. (...) Accounts of non-reductive realization conforming to this condition are implementing what I call 'the powers-based subset strategy'. I focus on the crucial case involving mental and brain states; the results may be generalized, as appropriate. I first situate and motivate the strategy by attention to the problem of mental causation; I make the case, in schematic terms, that implementation of the strategy makes room (contra Kim 1989, 1993, 1998, and elsewhere) for mental states to be ontologically and causally autonomous from their realizing physical states, without inducing problematic causal overdetermination, and compatible with both Physicalism and Non-reduction; and I show that several contemporary accounts of non-reductive realization (in terms of functional realization, parthood, and the determinable/determinate relation) are plausibly seen as implementing the strategy. As I also show, implementation of the powers-based strategy does not require endorsement of any particular accounts of either properties or causation---indeed, a categoricalist contingentist Humean can implement the strategy. The schematic location of the strategy in the space of available responses to the problem of mental (more generally, higher-level) causation, as well as the fact that the schema may be metaphysically instantiated, strongly suggests that the strategy is, appropriately generalized and instantiated, sufficient and moreover necessary for non-reductive realization. I go on to defend the sufficiency and necessity claims against a variety of objections, considering, along the way, how the powers-based subset strategy fares against competing accounts of purportedly non-reductive realization in terms of supervenience, token identity, and constitution. (shrink)

I problematize Grounding-based formulations of physicalism. More specifically, I argue, first, that motivations for adopting a Grounding-based formulation of physicalism are unsound; second, that a Grounding-based formulation lacks illuminating content, and that attempts to imbue Grounding with content by taking it to be a strict partial order are unuseful and problematic ; third, that conceptions of Grounding as constitutively connected to metaphysical explanation conflate metaphysics and epistemology, are ultimately either circular or self-undermining, and controversially assume that physical dependence is incompatible (...) with explanatory gaps; fourth, that in order to appropriately distinguish physicalism from strong emergentism, a Grounding-based formulation must introduce one and likely two primitives in addition to Grounding; and fifth, that understanding physical dependence in terms of Grounding gives rise to ‘spandrel’ questions, including, e.g., “What Grounds Grounding?”, which arise only due to the overly abstract nature of Grounding. (shrink)

How can mental properties bring about physical effects, as they seem to do, given that the physical realizers of the mental goings-on are already sufficient to cause these effects? This question gives rise to the problem of mental causation (MC) and its associated threats of causal overdetermination, mental causal exclusion, and mental causal irrelevance. Some (e.g., Cynthia and Graham Macdonald, and Stephen Yablo) have suggested that understanding mental-physical realization in terms of the determinable/determinate relation (henceforth, 'determination') provides the key to (...) solving the problem of MC: if mental properties are determinables of their physical realizers, then (since determinables and determinates are distinct, yet don't causally compete) all three threats may be avoided. Not everyone agrees that determination can do this good work, however. Some (e.g., Douglas Ehring, Eric Funkhauser, and Sven Walter) object that mental-physical realization can't be determination, since such realization lacks one or other characteristic feature of determination. I argue that on a proper understanding of the features of determination key to solving the problem of MC these arguments can be resisted. (shrink)

The co-instantiation thesis is pivotal to a significant solution to the problem of causal exclusion. But this thesis has been subject to some powerful objections. In this paper, I argue that these difficulties arise because the thesis lacks the necessary metaphysical framework in which its claims should be interpreted and understood. Once this framework is in place, we see that the co-instantiation thesis can answer its critics. The result is a rehabilitated co-instantiation solution to the troubling problem of causal exclusion. (...) But questions remain concerning the viability of certain of its applications. (shrink)

Mental causation, our mind's ability to causally affect the course of the world, is part and parcel of our ‘manifest image’ of the world. That there is mental causation is denied by virtually no one. How there can be such a thing as mental causation, however, is far from obvious. In recent years, discussions about the problem of mental causation have focused on Jaegwon Kim's so-called Causal Exclusion Argument, according to which mental events are ‘screened off’ or ‘preempted’ by physical (...) events unless mental causation is a genuine case of overdetermination or mental properties are straightforwardly reducible to physical properties.

Nonreductivist physicalists are increasingly regarded as unwitting epiphenomenalists, since their refusal to reduce mental traits to physical properties allegedly implies that even if there are mental causes, none of them produces its effects by virtue of its being a type of mental state. I examine and reject a reply to this concern that relies on the idea of ​​"tropes". I take the failure of the tropes-based model of causal relevance to illustrate a confusion at the heart of the notion of (...) causal relevance, a notion that is central to the critique of non-reductive physicalism. I aim to dispel the idea that non-reductive physicalism is committed to epiphenomenalism. (shrink)

For the nonreductive physicalist, behavioural effects have a complete physiological explanation and a distinct psychological explanation. In a series of papers Jaegwon Kim argues that there can be no more than a single complete and independent explanation of any one event, thereby excluding the psychological explanation. For his own part, Kim includes psychological explanations through the use of an extensional model of explanatory individuation. Numerous critics have pointed out the counterintuitive results of this extensional model of explanatory individuation. In a (...) recent article in this journal, Neil Campbell suggests that Kim's property exemplification account of events provides the conceptual resources to dodge this objection. In this article I argue that this appeal to the property exemplification account does not work in the crucial case of mental explanation. (shrink)

In recent decades, a view of identity I call Sortalism has gained popularity. According to this view, if a is identical to b, then there is some sortal S such that a is the same S as b. Sortalism has typically been discussed with respect to the identity of objects. I argue that the motivations for Sortalism about object-identity apply equally well to event-identity. But Sortalism about event-identity poses a serious threat to the view that mental events are token identical (...) to physical events: A particular mental event m is identical with a particular physical event p only if there is a sortal S such that m and p are both Ss. If there is no such sortal, the doctrine of token-identity is not true. I argue here that we have no good reason for thinking that there is any such sortal. (shrink)

A Lockean metaphysics of belief that understands outright belief as a determinable with degrees of confidence as determinates is supposed to effect a unification of traditional coarse-grained epistemology of belief with fine-grained epistemology of confidence. But determination of belief by confidence would not by itself yield the result that norms for confidence carry over to norms for outright belief unless belief and high confidence are token identical. We argue that this token-identity thesis is incompatible with the neglected phenomenon of “mistuned (...) knowledge” – knowledge in the absence of rational confidence. We show how partial epistemological unification can be secured, even without token identity, given determination of outright belief by degrees of confidence. Finally, we suggest a direction for the pursuit of thoroughgoing epistemological unification. (shrink)

This paper tries to show that Kim's strategy of preventing the problem of generalization of mental causation is not successful and that his original supervenience argument can be applied to cases of nonmental macrolevel causation, with the effect that nonmental macroproperties which only supervene on, but are not identical with, configurations of microproperties turn out to be epiphenomenal after all.

Philosophers and scientists are concerned with the why and the how of things. Questions like the following are so much grist for the philosopher’s and scientist’s mill: How can we be free and yet live in a deterministic universe?, How do neural processes give rise to conscious experience?, Why does conscious experience accompany certain physiological events at all?, How is a three-dimensional perception of depth generated by a pair of two-dimensional retinal images?. Since Belnap and Steel’s pioneering work on the (...) logic of questions, Van Fraassen has managed to apply their approach in constructing an account of the logic of why-questions. Comparatively little, by contrast, has been written on the logic of how-questions despite the apparent centrality of questions such as How is it possible for us to be both free and determined? to philosophical enterprise.1 In what follows I develop a logic for how-questions of various sorts including how-questions of cognitive resolution, how-questions of manner, how-questions of method, of means, and of mechanism.

In this paper, I assess the ontological commitments of frame-based methods of knowledge representation. Frames decompose concepts into recursive attribute-value structures. Attributes are the general aspects by which a category or individual is described; their values are more or less specific properties that are assigned to the referential object. The question is: are these properties to be interpreted as universals or as tropes? Some trope theorists allege that an interpretation in terms of universals is incompatible with frames for individuals in (...) which the values of quality attributes are recursively specified by further attributes. I shall argue, however, that recursive extension poses a challenge, not specifically to the universals realist, but rather to realists about determinables as opposed to determinables nominalists. Moreover, it is suggested that even determinables realists are able to cope with recursively extended frames once they relativize relations between determinables and determinates to particular objects. It is indicated how these findings might bear on adjacent debates in the metaphysics of natural language. (shrink)

Several philosophers (e.g., Ehring (Nous (Detroit, Mich.) 30:461–480, 1996 ); Funkhouser (Nous (Detroit, Mich.) 40:548–569, 2006 ); Walter (Canadian Journal of Philosophy 37:217–244, 2007 ) have argued that there are metaphysical differences between the determinable-determinate relation and the realization relation between mental and physical properties. Others have challenged this claim (e.g., Wilson (Philosophical Studies, 2009 ). In this paper, I argue that there are indeed such differences and propose a “mechanistic” account of realization that elucidates why these differences hold. This (...) account of realization incorporates two distinct roles that mechanisms play in the realization of mental (and other special science) properties which are implicit, but undeveloped, in the literature—what I call “constitutive” and “integrative” mechanisms. I then use these two notions of mechanism to clarify some debates about the relations between realization, multiple realizability, and irreducibility. (shrink)

Trope theory is an increasingly prominent contender in contemporary debates about the existence and nature of properties. But it suffers from ambiguity concerning the nature of a trope. Disambiguation reveals two fundamentally different concepts of a trope: modifier tropes and module tropes. These types of tropes are unequally suited for metaphysical work. Modifier tropes have advantages concerning powers, relations, and fundamental determinables, whereas module tropes have advantages concerning perception, causation, character-grounding, and the ontology of substance. Thus, the choice between modifier (...) tropes and module tropes is significant and divides the advantages of trope theory simpliciter. In addition, each resulting trope theory is unstable: modifier trope theory threatens to collapse into realism and module trope theory threatens to collapse into austere nominalism. This invites reflection on the stability of trope theory in general. (shrink)

I outline two ways of reading what is at issue in the exclusion problem faced by non-reductive physicalism, the “vertical” versus “horizontal”, and argue that the vertical reading is to be preferred to the horizontal. I discuss the implications: that those who have pursued solutions to the horizontal reading of the problem have taken a wrong turn.

Emergence is a notorious philosophical term of art. A variety of theorists have appropriated it for their purposes ever since George Henry Lewes gave it a philosophical sense in his 1875 Problems of Life and Mind. We might roughly characterize the shared meaning thus: emergent entities (properties or substances) ‘arise’ out of more fundamental entities and yet are ‘novel’ or ‘irreducible’ with respect to them. (For example, it is sometimes said that consciousness is an emergent property of the brain.) Each (...) of the quoted terms is slippery in its own right, and their specifications yield the varied notions of emergence that we discuss below. There has been renewed interest in emergence within discussions of the behavior of complex systems and debates over the reconcilability of mental causation, intentionality, or consciousness with physicalism. (shrink)

Motivated by the seeming structure of the sciences, metaphysical emergence combines broadly synchronic dependence coupled with some degree of ontological and causal autonomy. Reflecting the diverse, frequently incompatible interpretations of the notions of dependence and autonomy, however, accounts of emergence diverge into a bewildering variety. Here I argue that much of this apparent diversity is superficial. I first argue, by attention to the problem of higher-level causation, that two and only two strategies for addressing this problem accommodate the genuine emergence (...) of special science entities. These strategies in turn suggest two distinct schema for metaphysical emergence---'Weak' and 'Strong' emergence, respectively. Each schema imposes a condition on the powers of entities taken to be emergent: Strong emergence requires that higher-level features have more token powers than their dependence base features, whereas Weak emergence requires that higher-level features have a proper subset of the token powers of their dependence base features. Importantly, the notion of “power” at issue here is metaphysically neutral, primarily reflecting commitment just to the plausible thesis that what causes an entity may bring about are associated with how the entity is---that is, with its features.

Mental causation is a problem and not just a problem for the nonphysicalist. One of the many lessons learned from Jaegwon Kim’s writings in the philosophy of mind is that mental causation is a problem for the nonreductive physicalist as well. A central component of the common sense picture we have of ourselves as persons is that our beliefs and desires causally explain our actions. But the completeness of the “brain sciences” threatens this picture. If all of our actions are (...) causally explained by neurophysiological events occurring in our brains, what causal role is left for our reasons and motives? It would seem that these brain events do all the causal work there is to do, thus robbing the mental of its efficacy altogether or else making it a merely superfluous or redundant causal factor. This essay presents a systematic treatment of this exclusion dilemma from the perspective of a nonreductive physicalist. I argue that both horns of this dilemma can be avoided if we ground mental causation in counterfactual dependence between distinct events and understand the mind-body relation as event realization. Although in the final analysis our actions are overdetermined by their mental and neurophysiological antecedents, this overdetermination is entirely unproblematic. (shrink)

In a series of recent papers, Cynthia MacDonald and Graham MacDonald offer a resolution to the twin problems of mental causation and mental causal relevance. They argue that the problem of mental causation is soluble via token monism – mental events are causally efficacious physical events. At the same time, the problem of mental causal relevance is solved by combining this causally efficacious mental property instance with the systematic co-variation between distinct mental properties of the cause and the action-theoretic properties (...) of the effect in question. In this paper we argue that the solution offered by Mac- Donald and MacDonald faces significant difficulties in resolving both of the twin problems of mental causation and mental causal relevance. (shrink)

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. (shrink)

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.

Twenty years ago Stephen Yablo developed his original theory of mental causation, which has drawn much attention ever since. By providing a detailed reconstruction of Yablo’s approach, this paper first demonstrates that a certain line of critique that has repeatedly been brought forward against Yablo over the last two decades misconstrues the core idea of the model. At the same time, the reconstruction reveals that Yablo’s approach is probably the first explicit version of the “new compatibilism” within the philosophy of (...) mind. This fairly young family of theories essentially claims a non-identity as well as a non-distinctness of mental and physical phenomena. The second part of the paper then demonstrates that the new compatibilist approaches in general, and Yablo’s theory in particular, even though they can resist much of the popular criticism, fall prey to a new theoretical trilemma once the nature of the respective analysantia is made explicit. Finally, a model of the psychophysical relation is developed that may allow the new compatibilists to escape the mentioned trilemma. (shrink)

For philosophers interested in ontological issues, the writings of the important figures of Austrian philosophy in the nineteenth and early twentieth century contain many buried treasures to rediscover. Bernard Bolzano, Franz Brentano, Alexius Meinong, and Edmund Husserl, to name just four grand names of that period, were highly aware of the importance of a feasible ontology for many of the philosophical questions they addressed throughout their works.
