We address the thesis recently proposed by Andy Clark, that skill-mediated access to modality implies phenomenal feel. We agree that a skill theory of perception does indeed offer the possibility of a satisfactory account of the feel of perception, but we claim that this is not only through explanation of access to modality but also because skill actually provides access to perceptual property in general. We illustrate and substantiate our claims by reference to the recently proposed 'sensorimotor contingency' theory of (...) visual awareness. We discuss why this theory offers a distinctively attractive access-based approach to perceptual consciousness because it 'dereifies' experience and permits otherwise problematic aspects of phenomenal perceptual consciousness to be explained. We suggest our approach thus offers the prospect of 'naturalizing phenomenology'. (shrink)

Logical pluralism is the view that there is more than one correct logic. Most logical pluralists think that logic is normative in the sense that you make a mistake if you accept the premisses of a valid argument but reject its conclusion. Some authors have argued that this combination is self-undermining: Suppose that L1 and L2 are correct logics that coincide except for the argument from Γ to φ, which is valid in L1 but invalid in L2. If you accept (...) all sentences in Γ, then, by normativity, you make a mistake if you reject φ. In order to avoid mistakes, you should accept φ or suspend judgment about φ. Both options are problematic for pluralism. Can pluralists avoid this worry by rejecting the normativity of logic? I argue that they cannot. All else being equal, the argument goes through even if logic is not normative. (shrink)

C. S. Lewis is one of the most beloved Christian apologists of the twentieth century; David Hume and Bertrand Russell are among Christianity’s most important critics. This book puts these three intellectual giants in conversation with one another on various important questions: the existence of God, suffering, morality, reason, joy, miracles, and faith. Alongside irreconcilable differences, surprising areas of agreement emerge. Curious readers will find penetrating insights in the reasoned dialogue of these three great thinkers.

In his précis of a recent book, Richard Joyce writes, “My contention…is that…any epistemological benefit-of-the-doubt that might have been extended to moral beliefs…will be neutralized by the availability of an empirically confirmed moral genealogy that nowhere…presupposes their truth.” Such reasoning – falling under the heading “Genealogical Debunking Arguments” – is now commonplace. But how might “the availability of an empirically confirmed moral genealogy that nowhere… presupposes” the truth of our moral beliefs “neutralize” whatever “epistemological benefit-of-the-doubt that might have been extended (...) to” them? In this article, I argue that there appears to be no satisfactory answer to this question. The problem is quite general, applying to all arguments with the structure of Genealogical Debunking Arguments aimed at realism about a domain meeting two conditions. The Benacerraf-Field Challenge for mathematical realism affords an important special case. (shrink)

In everyday life we often act adequately, yet without deliberation. For instance, we immediately obtain and maintain an appropriate distance from others in an elevator. The notion of normativity implied here is a very basic one, namely distinguishing adequate from inadequate, correct from incorrect, or better from worse in the context of a particular situation. In the first part of this paper I investigate such ‘situated normativity’ by focusing on unreflective expert action. More particularly, I use Wittgenstein’s examples of craftsmen (...) (tailors and architects) absorbed in action to introduce situated normativity. Situated normativity can be understood as the normative aspect of embodied cognition in unreflective skillful action. I develop Wittgenstein’s insight that a peculiar type of affective behaviour, ‘directed discontent’, is essential for getting things right without reflection. Directed discontent is a reaction of appreciation in action and is introduced as a paradigmatic expression of situated normativity. In the second part I discuss Wittgenstein’s ideas on the normativity of what he calls ‘blind’ rule-following and the ‘bedrock’ of immediate action. What matters for understanding the normativity of (even ‘blind’) rule-following, is not that one has the capacity for linguistic articulation or reflection but that one is reliably participating in a communal custom. In the third part I further investigate the complex relationships between unreflective skillful action, perception, emotion, and normativity. Part of this entails an account of the link between normativity at the level of the expert’s socio-cultural practice and the individual’s situated and lived normativity. (shrink)

The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a non-substitutable species, but in many (...) cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

Angesichts der ökologischen Krise und der zunehmenden Zivilisationsprobleme ist es notwendig, einen philosophischen Naturbegriff, der das Verhältnis des Menschen zur Natur aufgrund dieser Tatsache neu bestimmt, zu entwickeln. Der Jesuit, Paläontologe und Philosoph Pierre Teilhard de Chardin (1881-1955) ist ein herausragendes Beispiel einer Vermittlung von Naturwissenschaft und Naturphilosophie. Teilhard entwirft eine Zusammenschau von transzendent-metaphysischer Teleologie, die aus dem christlichen Glauben heraus Gott als einzige Zweckursache des Geschehens sieht, philosophischer Anthropologie und naturwissenschaftlich orientierter kausalmechanischer Evolutionstheorie, dem allmählichen Entwickeln eines höheren Zustands (...) aus einem vorhergehenden. Die in der Ursache gegründeten Seinszusammenhänge ergeben einen vom Ziel her bestimmten Zusammenhang. Gott ist Totum alles wirklich Seienden im Horizont des möglichen Seins. Das für Teilhard so wichtige teleologische Prinzip hat seinen philosophiehistorischen Ursprung bei Aristoteles, der damit eine Denktradition begründete, die im Gegensatz zum kausal-mechanischen Weltbild der Naturwissenschaften steht und die sich über Thomas von Aquin und Hegel bis zu Teilhard als vorläufig letztem Höhepunkt erhält. Der aus Teilhards Naturphilosophie folgende Optimismus kann von großer Bedeutung für die Gegenwart sein. Er resultiert aus der Übernahme von Verantwortung für die Schöpfung und ist die ethische Konsequenz aus Naturfinalität und christlichem Universalismus. Der Autor: Erik Lehnert, geb. 1975 in Berlin.

It is widely agreed that the intelligibility of modal metaphysics has been vindicated. Quine's arguments to the contrary supposedly confused analyticity with metaphysical necessity, and rigid with non-rigid designators.2 But even if modal metaphysics is intelligible, it could be misconceived. It could be that metaphysical necessity is not absolute necessity – the strictest real notion of necessity – and that no proposition of traditional metaphysical interest is necessary in every real sense. If there were nothing otherwise “uniquely metaphysically significant” about (...) metaphysical necessity, then paradigmatic metaphysical necessities would be necessary in one sense of “necessary”, not necessary in another, and that would be it. The question of whether they were necessary simpliciter would be like the question of whether the Parallel Postulate is true simpliciter – understood as a pure mathematical conjecture, rather than as a hypothesis about physical spacetime. In a sense, the latter question has no objective answer. In this article, I argue that paradigmatic questions of modal metaphysics are like the Parallel Postulate question. I then discuss the deflationary ramifications of this argument. I conclude with an alternative conception of the space of possibility. According to this conception, there is no objective boundary between possibility and impossibility. Along the way, I sketch an analogy between modal metaphysics and set theory. (shrink)

This paper examines three views of what an omission or an instance of refraining is. The view advanced is that in many cases, an omission is simply an absence of an action of some type. However, generally one’s not doing a certain thing counts as an omission only if there is some norm, standard, or ideal that calls for one’s doing that thing.

One can (for the most part) formulate a model of a classical system in either the Lagrangian or the Hamiltonian framework. Though it is often thought that those two formulations are equivalent in all important ways, this is not true: the underlying geometrical structures one uses to formulate each theory are not isomorphic. This raises the question of whether one of the two is a more natural framework for the representation of classical systems. In the event, the answer is yes: (...) I state and sketch proofs of two technical results—inspired by simple physical arguments about the generic properties of classical systems—to the effect that, in a precise sense, classical systems evince exactly the geometric structure Lagrangian mechanics provides for the representation of systems, and none provided by Hamiltonian. The argument not only clarifies the conceptual structure of the two systems of mechanics, but also their relations to each other and their respective mechanisms for representing physical systems. It also shows why naïvely structural approaches to the representational content of physical theories cannot work. [Lagrange] grasped that he had gained a method of stating dynamical truths in a way, which is perfectly indifferent to the particular methods of measurement employed in fixing the positions of the various parts of the system. Accordingly, he went on to deduce equations of motion, which are equally applicable whatever quantitative measurements have been made, provided that they are adequate to fix positions. The beauty and almost divine simplicity of these equations is such that these formulae are worthy to rank with those mysterious symbols which in ancient times were held directly to indicate the Supreme Reason at the base of all things.

In Consequentialism Reconsidered, Carlson strives to find a plausible formulation of the structural part of consequentialism. Key notions are analyzed, such as outcomes, alternatives and performability. Carlson argues that consequentialism should be understood as a maximizing rather than a satisficing theory, and as temporally neutral rather than future oriented. He also shows that certain moral theories cannot be reformulated as consequentialist theories. The relevant alternatives for an agent in a situation are taken to comprise all actions that they can perform (...) in the situation. The defense of this idea necessitates certain modifications to the standard consequentialist criteria of obligatoriness, rightness and wrongness. The problem of whether agents should adapt their actions to their own future actions is also addressed. Further, a conditional analysis of performability is suggested, and it is argued that particular actions should in this connection be regarded as `abstract' rather than `concrete'. The final chapter sketches a consequentialist theory for collective agents. (shrink)

The distinction between perception and cognition frames countless debates in philosophy and cognitive science. But what, if anything, does this distinction actually amount to? In this introductory article, we summarize recent work on this question. We first briefly consider the possibility that a perception-cognition border should be eliminated from our scientific ontology, and then introduce and critically examine five positive approaches to marking a perception–cognition border, framed in terms of phenomenology, revisability, modularity, format, and stimulus-dependence.

Maintaining systems of military plans is critical for military effectiveness, but is also challenging. Plans will become obsolete as the world diverges from the assumptions on which they rest. If too many ad hoc changes are made to intermeshed plans, the ensemble may no longer lead to well-synchronized and coordinated operations, resulting in the system of plans becoming itself incoherent. We describe in what follows an Adaptive Planning process that we are developing on behalf of the Air Force Research Laboratory (...) (Rome) with the goal of addressing problems of these sorts through cyclical collaborative plan review and maintenance. The interactions of world state, blue force status and associated plans are too complex for manual adaptive processes, and computer-aided plan review and maintenance is thus indispensable. We argue that appropriate semantic technology can 1) provide richer representation of plan-related data and semantics, 2) allow for flexible, non-disruptive, agile, scalable, and coordinated changes in plans, and 3) support more intelligent analytical querying of plan-related data.

The book revives the neutral monism of Mach, James, and Russell and applies the updated view to the problem of redefining physicalism, explaining the origins of sensation, and the problem of deriving extended physical objects and systems from an ontology of events.

ABSTRACT Glen Pettigrove wishes to accommodate the thought that exemplary instances of love, forgiveness and ambition need not be strictly proportional to the value present in their objects and that agents who are excellent may value the same things somewhat differently from one another or differently over time. To make room for these attractive ideas, he sketches an approach according to which (i) the virtuous agent’s particular modus operandi constitutes an important locus of value and (ii) the value of virtue (...) is sui generis. I note that the principle of universalizability threatens his project. I sketch a way to reject this principle that agrees with the thesis that an agent’s modus operandi may be an important locus of value but puts pressure on the thesis that the value of virtue is sui generis. I question whether Pettigrove needs the second thesis. (shrink)

There are several theses in political science that are usually explicitly called ‘laws’. Other theses are generally thought of as laws, but often without being explicitly labelled as such. Still other claims are well-supported and arguably interesting, while no one would be tempted to call them laws. This situation raises philosophical questions: which theses deserve to be called laws and which not? And how should we decide about this? In this paper we develop and motivate a strategy for thinking about (...) laws in political science which integrates two core concepts: spatio-temporal stability and social mechanisms. The proposed strategy is a set of guidelines that political scientists can use to reflect on and argue about specific cases within their discipline, not a clear-cut demarcation criterion. We defend and motivate this strategy and apply it to two cases (one with respect to state repression, one about parliamentary elections). After we have developed and motivated our strategy for political science, we show that our proposal is relevant for other disciplines in the social sciences. We explain how our views fit into critical realism and embed them in the debate on laws in general philosophy of science and in the philosophy of the social sciences. (shrink)

Erik Wielenberg has presented an objection to divine command theory (DCT) alleging that DCT has the troubling implication that psychopaths have no moral obligations. Matthew Flannagan has replied to Wielenberg’s argument. Here, I defend the view that, despite Flannagan’s reply, the psychopath objection presents a serious problem for the versions of DCT defended by its most prominent contemporary advocates — Robert Adams, C. Stephen Evans, and William Lane Craig.

A consideration of Mach's elements, his philosophy of neutral monism, and philosophy of physics, especially space and time, much of it based on unpublished writings from the Nachlass and other original sources. The historical connection between Mach and logical positivism is shown to be superficial at best, and Mach's elements are shown to be mind independent natural qualities (world-elements) with dynamic force, not limited to human sensations.

This essential guide to paradoxes takes the reader on a lively tour of puzzles that have taxed thinkers from Zeno to Galileo and Lewis Carroll to Bertrand Russell. Michael Clark uncovers an array of conundrums, such as Achilles and the Tortoise, Theseus' Ship, Hempel's Raven, and the Prisoners' Dilemma, taking in subjects as diverse as knowledge, ethics, science, art and politics. Clark discusses each paradox in non-technical terms, considering its significance and looking at likely solutions.

Samuel Clarke was by far the most gifted and influential Newtonian philosopher of his generation, and A Demonstration of the Being and Attributes of God, which constituted the 1704 Boyle Lectures, was one of the most important works of the first half of the eighteenth century, generating a great deal of controversy about the relation between space and God, the nature of divine necessary existence, the adequacy of the Cosmological Argument, agent causation, and the immateriality of the soul. Together (...) with the other texts presented in this edition, it also provides the best introduction to Clarke's philosophical views, which, in addition to their intrinsic interest, are historically important for the light they shed both on the philosophical positions within the Newtonian circle and on the exchange between Clarke and Leibniz, the most famous philosophical controversy of the eighteenth century.

In Freedom: An Impossible Reality, Ray Tallis argues that we escape imprisonment by causal determinism, and thus gain free will, by the virtual distance from natural laws afforded us by intentionality, a human capacity that he claims cannot be naturalized. I respond that we can’t know in advance that intentionality will never be subsumed by science, and that our capacities to entertain possibilities and decide among them are natural cognitive endowments that supervene on generally reliable neural processes. Moreover, any disconnection (...) from the multi-level determinants that account for human behavior cannot augment, but would likely undermine, effective human agency. Our full inclusion in nature, understood in terms of a pragmatic, explanatory determinism, is therefore not a prison from which we need to escape. (shrink)

The Precautionary Principle is both celebrated and criticized. It has become an important principle for decision making, but it is also subject to criticism. One problem that is often pointed out with the principle is that is not clear what it actually says and how to use it. I have taken on this problem by performing an analysis of some of the most influential formulations of the principle in an attempt to identify the core ideas behind it, with the purpose (...) of producing a formulation of the principle that is clear and practically applicable. It was found that what is called the Precautionary Principle is not a principle that tells us what do to achieve extra precaution or how to handle situations when extra precaution is called for. Instead, it was found to be a list of circumstances that each justify extra precaution. An analysis of some of the most common and influential formulations of the Precautionary Principle identified four such circumstances: (1) When we deal with important values that tend to be systematically downplayed by traditional decision methods – such as human health and the environment. (2) When we suspect that the decision might lead to irreversible and severe consequences and the values at stake are also irreplaceable, (3) When timing is at least as important as being right. (4) When it is more important to avoid false negatives than false positives. This interpretation of the Precautionary Principle does not say anything about what kind of actions to take when extra precaution is called for, but it does provide a clear and practically useful list of circumstances that call for extra precaution and that is not subject to the most common objections to the Precautionary Principle.

Ruth Chang has defended a concept of "parity", implying that two items may be evaluatively comparable even though neither item is better than or equally good as the other. This article takes no stand on whether there actually are cases of parity. Its aim is only to make the hitherto somewhat obscure notion of parity more precise, by defining it in terms of the standard value relations. Given certain plausible assumptions, the suggested definiens is shown to state a necessary and (...) sufficient condition for parity, as this relation is envisaged by Chang. (shrink)

I this article, I introduce the notion of pluralism about an area, and use it to argue that the questions at the center of our normative lives are not settled by the facts -- even the normative facts. One upshot of the discussion is that the concepts of realism and objectivity, which are widely identified, are actually in tension. Another is that the concept of objectivity, not realism, should take center stage.

In a discussion of Parfit's Drops of Water case, Zach Barnett has recently proposed a novel argument against “No Small Improvement”; that is, the claim that a single drop of water cannot affect the magnitude of a thirsty person's suffering. We first show that Barnett's argument can be significantly strengthened, and also that the fundamental idea behind it yields a straightforward argument for the transitivity of equal suffering. We then suggest that defenders of No Small Improvement could reject a Pareto (...) principle that is presupposed in Barnett's argument and our developments of it. However, this does not save No Small Improvement, since there is a convincing argument against this claim that does not presuppose the Pareto principle. (shrink)

John Broome has argued that incomparability and vagueness cannot coexist in a given betterness order. His argument essentially hinges on an assumption he calls the ‘collapsing principle’. In an earlier article I criticized this principle, but Broome has recently expressed doubts about the cogency of my criticism. Moreover, Cristian Constantinescu has defended Broome’s view from my objection. In this paper, I present further arguments against the collapsing principle, and try to show that Constantinescu’s defence of Broome’s position fails.

Much controversy surrounds the question of what ought to be the proper definition of 'singularity' in general relativity, and the question of whether the prediction of such entities leads to a crisis for the theory. I argue that a definition in terms of curve incompleteness is adequate, and in particular that the idea that singularities correspond to 'missing points' has insurmountable problems. I conclude that singularities per se pose no serious problem for the theory, but their analysis does bring into (...) focus several problems of interpretation at the foundation of the theory often ignored in the philosophical literature.

The aim of this chapter is to use philosophy and, in particular ethical theory, to identify and explore some potential conflicts.

Gerald Harrison identifies two Euthyphro-related concerns for divine command theories and makes the case that to the extent that these concerns make trouble for divine command theories they also make trouble for non-naturalistic moral realism and naturalistic moral realism. He also offers responses to the two concerns on behalf of divine command theorists. I show here that the parity thesis does not hold for the most commonly discussed version of divine command theory. I further argue that his responses to the (...) two concerns fail. Finally, I draw on some of Harrison’s ideas to identify an advantage that non-naturalistic moral realism has over divine command theories and naturalistic moral realism. (shrink)

A full appreciation for Ernst Mach's doctrine of the economy of thought must take account of his direct realism about particulars (elements) and his anti-realism about space-time laws as economical constructions. After a review of thought economy, its critics and some contemporary forms, the paper turns to the philosophical roots of Mach's doctrine. Mach claimed that the simplest, most parsimonious theories economized memory and effort by using abstract concepts and laws instead of attending to the details of each individual event (...) or experiment. For Mach, the individual case never truly repeated in all of its uniqueness, nor was all of the individual detail of a physical element adequately captured in abstract laws and schemata, however necessary these were for the pursuit of science. As can be shown from specific passages, some already published, some not, Mach's elements included physical qualia in nature similar to Russell's unsensed sensibilia, which existed even where there were no conscious observers. An argument will be presented to make the case that Mach believed in the mind-independent elements from the 1870s on, while other aspects of his thought evolved over time; I have thus dated the references to reflect this historical progression. I concentrate on Mach's ontology, as it bears on economy of thought, not his epistemology per se, which might well have been restricted to observable elements/sensations. After his own conversion to neutral monism, in the 1920s, Bertrand Russell echoed Mach's call for a 'future science' capable of handling the 'intrinsic character' of qualitative data directly without the excessive abstraction of physics.

Analyzing how Plotinus’ critical reception of the Aristotelian, Stoic and Middle-Platonist notions of 'that which depends on us' lead him to a highly original interpretation of the notion, this book shows the central role of this notion in the Plotinian account of human agency.

Dennett depicts human minds as both deeply different from, yet profoundly continuous with, the minds of other animals and simple agents. His treatments of mind, consciousness, free will and human agency all reflect this distinctive dual perspective. There is, on the one hand, the (in)famous Intentional Stance, relative to which humans, dogs, insects and even the lowly thermostat (e.g. Dennett (1998) p.327) are all pronounced capable of believing and desiring in essentially the same theoretical sense. And there is, on the (...) other hand, a noteworthy (and increasing) insistence that human minds are special in that they exhibit a distinctive kind of “informational organization”: one that confers consciousness (Dennett (1998) p.347), and creates the space for agency, purpose, self-control (Dennett (1984) p.100), and “significant suffering” (Dennett (1998) p.351). What follows is a critical examination of this dual perspective, and of Dennett’s account of the key factor that makes us special - human language and our immersion in the sea of culture (Dennett (1998) p.146, (1996) p.130, (in press) p.7). In particular, I shall ask whether Dennett’s dual perspective masks a deeper tension in his accounts of consciousness and personhood, and whether the appeal to the transformative power of human language and culture can bear the heavy explanatory burden Dennett places upon it. These turn out to be significant challenges but ones which also help clarify the scope and power of this complex, multi-layered account. I end by commenting briefly on the wider significance of Dennett’s project as a major contribution to current debates concerning the continuity (or otherwise) of evolved cognitive strategies and the essentially hybrid (biological and non-biological) nature of human minds and persons.
