The paper offers a new account of Spinoza's conception of “substance”, the fundamental building block of reality. It shows that it can be demonstrated apriori within Spinoza's metaphysical framework that (i) contrary to Idealist readings, for Spinoza there can be no substance that is not determined or modified by some other entity produced by substance; and that (ii) there can be no substance (and hence no being) that is not a thinking substance.

In this entry I will offer a systematic novel taxonomy of our imaginative abilities coherent with standard treatments in cognitive science, philosophy of mind and aesthetics. In particular, I will distinguish between the non-propositional imagination and the propositional imagination, which include several further sub-varieties such as the objectual imagination, imagery, experiential imagination, supposition, make-believe and more.

I present an approach to our conceiving absolute impossibilities—things which obtain at no possible world—in terms of ceteris paribus intentional operators: variably restricted quantifiers on possible and impossible worlds based on world similarity. The explicit content of a representation plays a role similar in some respects to the one of a ceteris paribus conditional antecedent. I discuss how such operators invalidate logical closure for conceivability, and how similarity works when impossible worlds are around. Unlike what happens with ceteris paribus counterfactual (...) conditionals, the closest worlds are relevantly closest belief-worlds: closest to how things are believed to be, rather than to how they are. Also, closeness takes into account apriority and the opacity of intentional contexts. (shrink)

Why do we tend to ascribe possibility to what we can imagine? One strategy for answering that question involves the thought that, just as sensory episodes often involve its seeming to us as though the world is certain ways, so imaginings involve its seeming to us that what we have imagined is possible. This chapter argues that while some imaginings do feature appearances of possibility, very many others do not; and it explores the broader relevance of its conclusions for modal (...) epistemology.

My aim in this paper is to give a philosophical analysis of the relationship between contingently available technology and the knowledge that it makes possible. My concern is with what specific subjects can know in practice, given their particular conditions, especially available technology, rather than what can be known “in principle” by a hypothetical entity like Laplace’s Demon. The argument has two parts. In the first, I’ll construct a novel account of epistemic possibility that incorporates two pragmatic conditions: responsibility and (...) practicability. For example, whether subjects can gain knowledge depends in some circumstances on whether they have the capability of gathering relevant evidence. In turn, the possibility of undertaking such investigative activities depends in part on factors like ethical constraints, economical realities, and available technology. In the second part of the paper, I’ll introduce “technological possibility” to analyze the set of actions made possible by available technology. To help motivate the problem and later test my proposal, I’ll focus on a specific historical case, one of the earliest uses of digital electronic computers in a scientific investigation. I conclude that the epistemic possibility of gaining access to scientific knowledge about certain subjects depends (in some cases) on the technological possibility for making responsible investigations.

In a recent article Mark Ian Thomas Robson argues that there is a clear contradiction between the view that possible worlds are a part of God's nature and the theologically pivotal, but philosophically neglected, claim that God is perfectly beautiful. In this article I show that Robson's argument depends on several key assumptions that he fails to justify and as such that there is reason to doubt the soundness of his argument. I also demonstrate that if Robson's argument were sound (...) then this would be a problem for all classical theists and not just those who hold the possible worlds view. (shrink)

Necessitarian accounts of the laws of nature meet an apparent difficulty: for them, counterlegal conditionals, despite appearing to be substantive, seem to come out as vacuous. I argue that the necessitarian may use the presuppositions of counterlegal discourse to explain this. If the typical presupposition that necessitarianism is false is made explicit in counterlegal utterances, we obtain sentences such as 'If it turns out that the laws of nature are contingent, then if the laws had been otherwise, then such and (...) such would have been the case', which are non-vacuous and very often true. This goes a long way towards resolving the difficulty for necessitarianism. (shrink)

The problem of imaginative resistance holds interest for aestheticians, literary theorists, ethicists, philosophers of mind, and epistemologists. We present a somewhat opinionated overview of the philosophical discussion to date. We begin by introducing the phenomenon of imaginative resistance. We then review existing responses to the problem, giving special attention to recent research directions. Finally, we consider the philosophical significance that imaginative resistance has—or, at least, is alleged to have—for issues in moral psychology, theories of cognitive architecture, and modal epistemology.

What is the relationship between pain and the body? I claim that pain is best explained as a type of personal experience and the bodily response during pain is best explained in terms of a type of mechanical neurophysiologic operation. I apply the radical philosophy of identity theory from philosophy of mind to the relationship between the personal experience of pain and specific neurophysiologic mechanism and argue that the relationship between them is best explained as one of type identity. Specifically, (...) pain is a specific type of personal experience identical to a specific type of allostatic stress response comprised of interdependent nervous, endocrine and immune mechanical operations.

Zombies are hypothetical creatures identical to us in behavior and internal functionality, but lacking experience. When the concept of zombie is examined in careful detail, it is found that the attempt to keep experience out does not work. So the concept of zombie is the same as the concept of person. Because they are only trivially conceivable, zombies are in a sense inconceivable.

The purpose of this thesis is to demonstrate that metaphysics is a necessary discipline -- necessary in the sense that all areas of philosophy, all areas of science, and in fact any type of rational activity at all would be impossible without a metaphysical background or metaphysical presuppositions. Because of the extremely strong nature of this claim, it is not possible to put forward a very simple argument, although I will attempt to construct one. A crucial issue here is what (...) metaphysics in fact is -- the nature of metaphysics. The conception of metaphysics which I support could be called Aristotelian, as opposed to Kantian: metaphysics is the first philosophy and the basis of all other philosophical and scientific inquiry. I will argue that this is indeed the most plausible conception of metaphysics. (shrink)

I focus on a key argument for global external world scepticism resting on the underdetermination thesis: the argument according to which we cannot know any proposition about our physical environment because sense evidence for it equally justifies some sceptical alternative (e.g. the Cartesian demon conjecture). I contend that the underdetermination argument can go through only if the controversial thesis that conceivability is per se a source of evidence for metaphysical possibility is true. I also suggest a reason to doubt that (...) conceivability is per se a source of evidence for metaphysical possibility, and thus to doubt the underdetermination argument. (shrink)

Could there be a cognitive zombie – that is, a creature with the capacity for cognition, but no capacity for consciousness? Searle argues that there cannot be a cognitive zombie because there cannot be an intentional zombie: on this view, there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and intentionality. However, I argue that there are good empirical reasons for rejecting the proposed connection between consciousness and intentionality. Instead, I argue (...) that there is a connection between consciousness and cognition that is derived from a more fundamental connection between consciousness and rationality. On this view, there cannot be a cognitive zombie because there cannot be a rational zombie. (shrink)

This article argues for two related theses. First, it defends a general thesis: any kind of necessity, including metaphysical necessity, can only be known a priori. Second, however, it also argues that the sort of a priori involved in modal metaphysical knowledge is not related to imagination or any sort of so-called epistemic possibility. Imagination is neither a proof of possibility nor a limit to necessity. Rather, modal metaphysical knowledge is built on intuition of philosophical categories and the structures they (...) form.

ABSTRACT: I explain and rebut four objections to the claim that attributions of intentional attitudes are normative judgments, all stemming, directly or indirectly, from the widespread assumption that the normative supervenes on the non-normative.

Abstract Timothy Williamson has recently proposed to undermine modal skepticism by appealing to the reducibility of modal to counterfactual logic ( Reducibility ). Central to Williamson’s strategy is the claim that use of the same non-deductive mode of inference ( counterfactual development , or CD ) whereby we typically arrive at knowledge of counterfactuals suffices for arriving at knowledge of metaphysical necessity via Reducibility. Granting Reducibility, I ask whether the use of CD plays any essential role in a Reducibility-based reply (...) to two kinds of modal skepticism. I argue that its use is entirely dispensable, and that Reducibility makes available replies to modal skeptics which show certain propositions to be metaphysically necessary by deductive arguments from premises the modal skeptic accepts can be known.

The distinction between essential versus accidental properties has been characterized in various ways, but it is currently most commonly understood in modal terms: an essential property of an object is a property that it must have, while an accidental property of an object is one that it happens to have but that it could lack. Let’s call this the basic modal characterization, where a modal characterization of a notion is one that explains the notion in terms of necessity/possibility. In the (...) characterization just given of the distinction between essential and accidental properties, the use of the word “must” reflects the fact that necessity is invoked, while the use of the word “could” reflects that possibility is invoked. The notions of necessity and possibility are interdefinable: to say that something is necessary is to say that its negation is not possible; to say that something is possible is to say that its negation is not necessary; to say that an object must have a certain property is to say that it could not lack it; and to say that an object could have a certain property is to say that it is not the case that it must lack it.

The essays collected in this volume are all concerned with the connection between fiction and truth. This question is of utmost importance to metaphysics, philosophy of language, philosophical logic and epistemology, raising in each of these areas and at their intersections a large number of issues related to creation, existence, reference, identity, modality, belief, assertion, imagination, pretense, etc. All these topics and many more are addressed in this collection, which brings together original essays written from various points of view by (...) philosophers of diverse trends. These essays constitute major contributions to the current debates that the connection between truth and fiction continually enlivens, and give a sense of the directions in which research on this question is heading.

It is commonly held that our intuitive judgements about imaginary problem cases are justified a priori, if and when they are justified at all. In this paper I defend this view — ‘rationalism’ — against a recent objection by Timothy Williamson. I argue that his objection fails on multiple grounds, but the reasons why it fails are instructive. Williamson argues from a claim about the semantics of intuitive judgements, to a claim about their psychological underpinnings, to the denial of rationalism. (...) I argue that the psychological claim — that a capacity for mental simulation explains our intuitive judgements — does not, even if true, provide reasons to reject rationalism. (More generally, a simulation hypothesis, about any category of judgements, is very limited in its epistemological implications: it is pitched at a level of explanation that is insensitive to central epistemic distinctions.) I also argue that Williamson’s semantic claim — that intuitive judgements are judgements of counterfactuals — is mistaken; rather, I propose, they are a certain kind of metaphysical possibility judgement. Several other competing proposals are also examined and criticized. (shrink)

The paper presents a dilemma for both epistemic and non-epistemic versions of conceivability-based accounts of modal knowledge. On the one horn, non-epistemic accounts do not elucidate the essentialist knowledge they would be committed to. On the other, epistemic accounts do not elucidate everyday life de re modal knowledge. In neither case, therefore, do conceivability accounts elucidate de re modal knowledge.

This chapter sketches what is considered the best interpretation of physicalism, rehearses the best way of defending it, and shows that the physicalism forthcoming is still going to be less than fully satisfying; it is going to leave us short of the satisfaction that might be expected from a philosophical theory. The chapter is organized into three sections. The first section gives an interpretation of physicalism in the spirit of Frank Jackson's; this involves a rich version under which the way (...) things are phenomenally is derivable in principle from physical premisses. The second sketches a representationalist or intentionalist argument for physicalism about phenomenal experience, one which also appeals to Jackson. The third section argues that even if we accept this case for a rich physicalism, still we should not expect to find the doctrine fully satisfying; the simulatory gap will stand between us and a sort of satisfaction that we might have expected to achieve.

The development of possible worlds semantics for modal claims has led to a more general application of that theory as a complete semantics for various formal and natural languages, and this view is widely held to be an adequate (philosophical) interpretation of the model theory for such languages. We argue here that this view generates a self-referential inconsistency that indicates either the falsity or the incompleteness of PWS.

Following the standard practice in sociology, cultural anthropology and history, sociologists, historians of science and some philosophers of science define scientific communities as groups with shared beliefs, values and practices. In this paper it is argued that in real cases the beliefs of the members of such communities often vary significantly in important ways. This has rather dire implications for the convergence defense against the charge of the excessive subjectivity of subjective Bayesianism because that defense requires that communities of Bayesian (...) inquirers share a significant set of modal beliefs. The important implication is then that given the actual variation in modal beliefs across individuals, either Bayesians cannot claim that actual theories have been objectively confirmed or they must accept that such theories have been confirmed relative only to epistemically insignificant communities.

This paper suggests a critique of the zombie argument that bypasses the need to decide on the truth of its main premises, and specifically, avoids the need to enter the battlefield of whether conceivability entails metaphysical possibility. It is argued that if we accept, as the zombie argument’s supporters would urge us, the assumption that an ideal reasoner can conceive of a complete physical description of the world without conceiving of qualia, the general principle that conceivability entails metaphysical possibility, and (...) the general principle that for any s and t the metaphysical possibility of s & − t entails that s does not necessitate t, we have to conclude not that materialism is false but rather that either materialism or the “mental paint” (or “phenomenist”) conception of phenomenality is false. And further, given the initial advantages of materialism, the fact that proponents of the zombie argument are not allowed to rely on arguments against materialism in confronting this dilemma, and difficulties with arguments in favor of phenomenism, we find ourselves pushed to reject the mental paint conception rather than materialism. Or at any rate, it is hard to see how the proponent of the zombie argument can carry the burden of proof that lies with her. Thus, whether or not those premises of the zombie argument are true, the argument fails to refute materialism. (shrink)

In the first part of the paper I reconstruct Kant’s proof of the existence of a ‘most real being’ while also highlighting the theory of modality that motivates Kant’s departure from Leibniz’s version of the proof. I go on to argue that it is precisely this departure that makes the being that falls out of the pre-critical proof look more like Spinoza’s extended natura naturans than an independent, personal creator-God. In the critical period, Kant seems to think that transcendental idealism (...) allows him to avoid this conclusion, but in the last section of the paper I argue that there is still one important version of the Spinozistic threat that remains. -/- .

Kant's speculative theistic proof rests on a distinction between “logical” and “real” modality that he developed very early in the pre-critical period. The only way to explain facts about real possibility, according to Kant, is to appeal to the properties of a unique, necessary, and “most real” being. Here I reconstruct the proof in its historical context, focusing on the role played by the theory of modality both in motivating the argument (in the pre-critical period) and, ultimately, in undoing it (...) as a source of knowledge of God's existence (in the critical period). Along the way I examine Kant's version of the now-popular “actualist” thesis that facts about what is possible must be explained by facts about what is actual. I conclude by discussing why the critical Kant claims both that there are rational grounds for accepting the conclusion of his theistic proof, and that such acceptance can not count as knowledge. This is important, I argue, because the same considerations ultimately motivate his prohibition on knowledge of things-in-themselves generally. -/- . (shrink)

Positivism, in its standard outlook, is normative contextualism: If legal reasons are content-independent, then their content may vary with the context or point of view. Despite several advantages vis-à-vis strong metaphysical conceptions of reasons, contextualism implies relativism, which may lead further to the fragmentation of the point of view of agency. In his Oxford Hart Lecture, Coleman put forward a fresh account of the moral semantics of legal content, one that lays claim to preserving the unity of agency while retaining (...) the social facts thesis, which has been a key intuition of positivism. The present essay identifies potential weaknesses with this account and proposes a reconstruction along rationalist lines: First, it advances a descriptive account of reflective agency that is delivered in terms of a modest conceptual analysis; secondly, this is combined with a context-sensitive or "buck-passing" account of value, which illustrates that substantive reasons for action must be anchored, ontologically speaking, to particular social practices (Social Dependency Thesis). In the end the unity of agency comes at an affordable price, for it is no longer necessary to resort to metaphysical necessity and the most demanding conditions this imposes, in order to defend it.

A modest transcendental argument is one that sets out merely to establish how things need to appear to us or how we need to believe them to be, rather than how things are. Stroud's claim to have established that all transcendental arguments must be modest in this way is criticised and rejected. However, a different case for why we should abandon ambitious transcendental arguments is presented: namely, that when it comes to establishing claims about how things are, there is no (...) reason to prefer transcendental arguments to arguments that rely on the evidence of the senses, making the former redundant in a way that modest transcendental arguments, which have a different kind of sceptical target, are not.

Functionalism in the philosophy of mind is the doctrine that what makes something a mental state of a particular type does not depend on its internal constitution, but rather on the way it functions, or the role it plays, in the system of which it is a part. This doctrine is rooted in Aristotle's conception of the soul, and has antecedents in Hobbes's conception of the mind as a “calculating machine”, but it has become fully articulated (and popularly endorsed) only (...) in the last third of the 20th century. Though the term ‘functionalism’ is used to designate a variety of positions in a variety of other disciplines, including psychology, sociology, economics, and architecture, this entry focuses exclusively on functionalism as a philosophical thesis about the nature of mental states.

Necessitarian accounts of the laws of nature have an apparent difficulty in accounting for counterlegal conditionals because, despite appearing to be substantive, on the necessitarian thesis they are vacuous. I argue that the necessitarian may explain the apparently substantive content of such conditionals by pointing out the presuppositions of counterlegal discourse. The typical presupposition is that a certain conceptual possibility has been realized; namely, that necessitarianism is false. (The idea of conceptual possibility is explicated in terms of recent work in (...) two-dimensional modal semantics.) If this sort of presupposition is made explicit in counterlegal utterances, we obtain a sentence such as: 'If it turns out that the laws of nature are contingent, then if the laws had been otherwise, then such and such would have been the case.' Sentences of this type are non-vacuous, and very often true. I argue that this goes a long way towards resolving the difficulty for necessitarianism. (shrink)

Authors have a lot of leeway with regard to what they can make true in their story. In general, if the author says that p is true in the fiction we’re reading, we believe that p is true in that fiction. And if we’re playing along with the fictional game, we imagine that, along with everything else in the story, p is true. But there are exceptions to these general principles. Many authors, most notably Kendall Walton and Tamar Szabó Gendler, (...) have discussed apparent counterexamples when p is “morally deviant”. Many other statements that are conceptually impossible also seem to be counterexamples. In this paper I do four things. I survey the range of counterexamples, or at least putative counterexamples, to the principles. Then I look to explanations of the counterexamples. I argue, following Gendler, that the explanation cannot simply be that morally deviant claims are impossible. I argue that the distinctive attitudes we have towards moral propositions cannot explain the counterexamples, since some of the examples don’t involve moral concepts. And I put forward a proposed explanation that turns on the role of ‘higher-level concepts’, concepts that if they are satisfied are satisfied in virtue of more fundamental facts about the world, in fiction, and in imagination.

This entry focuses on two of the more historically important monisms: existence monism and priority monism . Existence monism targets concrete objects and counts by tokens. This is the doctrine that exactly one concrete object exists. Priority monism also targets concrete objects, but counts by basic tokens. This is the doctrine that exactly one concrete object is basic, which will turn out to be the classical doctrine that the whole is prior to its parts.

Hume's Dictum (HD) says, roughly and typically, that there are no metaphysically necessary connections between distinct, intrinsically typed, entities. HD plays an influential role in metaphysical debate, both in constructing theories and in assessing them. One should ask of such an influential thesis: why believe it? Proponents do not accept Hume's arguments for his dictum, nor do they provide their own; however, some have suggested either that HD is analytic or that it is synthetic a priori (that is: motivated by (...) intuitions we have no good reason to question). Here I explore whether belief in HD is directly justified on either grounds. I motivate and present more formal characterizations of HD; I show that there are good prima facie cases to be made for HD's being analytic and for its being synthetic a priori; I argue that each of the prima facie cases fails, some things considered. I close by offering two suggestions for how belief in HD might be indirectly justified on argumentative grounds. (shrink)

Attitude reports are reports about people’s states of mind. They are reports about what people think, believe, know, know a priori, imagine, hate, wish, fear, and the like. So, for example, I might report that s knows p, or that she imagines p, or that she hates p, where p specifies the content to which s is purportedly related. One lively current debate centers around the question of what sort of specification is involved when such attitude reports are successful. Some (...) hold that it is specification of the precise content of a mental state; others hold that it is specification of the content of a mental state only relative to a mode of presentation; yet others hold that it is merely a description or characterization of the content of a mental state. After providing a brief introduction to the traditional debate on attitude reports, this entry argues that for certain kinds of knowledge reports and for so-called de re attitude reports, descriptive theories emerge as the most plausible. The entry concludes with a discussion of how the characterizing relation between attitude reports and mental states might be construed. (shrink)

I argue that it is possible, in the right circumstances, to see what the kind thing is to do: in the right circumstances, we can, literally, see deontic facts, as well as facts about others’ emotional states, and evaluative facts. In arguing for this, I will deploy a notion of non‐inferential perceptual belief or judgement according to which the belief or judgement is arrived at non‐inferentially in the phenomenological sense and yet is inferential in the epistemic sense. The ability to (...) arrive at these kinds of beliefs and judgements is part of virtue, and is also part of what it is to grasp thick ethical concepts in an engaged way. When we come to thinner evaluative and deontic facts and thinner ethical concepts, however, the requirements for non‐inferential perceptual belief and judgement are less easily met. Seeing what is the kind thing to do is one matter; seeing what is the right thing to do is another. (shrink)

Non-Cartesian substance dualism maintains that persons or selves are distinct from their organic physical bodies and any parts of those bodies. It regards persons as ‘substances’ in their own right, but does not maintain that persons are necessarily separable from their bodies, in the sense of being capable of disembodied existence. In this paper, it is urged that NCSD is better equipped than either Cartesian dualism or standard forms of physicalism to explain the possibility of mental causation. A model of (...) mental causation adopting the NCSD perspective is proposed which, it is argued, is consistent with all that is currently known about the operations of the human central nervous system, including the brain. Physicalism, by contrast, seems ill-equipped to explain the distinctively intentional or teleological character of mental causation, because it effectively reduces all such causation to ‘blind’ physical causation at a neurological level.

Physicalism is the thesis that everything is physical, or as contemporary philosophers sometimes put it, that everything supervenes on, or is necessitated by, the physical. The thesis is usually intended as a metaphysical thesis, parallel to the thesis attributed to the ancient Greek philosopher Thales, that everything is water, or the idealism of the 18th Century philosopher Berkeley, that everything is mental. The general idea is that the nature of the actual world (i.e. the universe and everything in it) conforms (...) to a certain condition, the condition of being physical. Of course, physicalists don't deny that the world might contain many items that at first glance don't seem physical — items of a biological, or psychological, or moral, or social nature. But they insist nevertheless that at the end of the day such items are either physical or supervene on the physical. (shrink)

Conceivability is an important source of our beliefs about what is possible; inconceivability is an important source of our beliefs about what is impossible. What are the connections between the reliability of these sources? If one is reliable, does it follow that the other is also reliable? The central contention of this paper is that suitably qualified the reliability of inconceivability implies the reliability of conceivability, but the reliability of conceivability fails to imply the reliability of inconceivability.

If zombies were conceivable in the sense relevant to the ‘conceivability argument’ against physicalism, a certain epiphenomenalistic conception of consciousness—the ‘e-qualia story’—would also be conceivable. But the e-qualia story is not conceivable because it involves a contradiction. The non-physical ‘e-qualia’ supposedly involved could not perform cognitive processing, which would therefore have to be performed by physical processes; and these could not put anyone into ‘epistemic contact’ with e-qualia, contrary to the e-qualia story. Interactionism does not enable zombists to escape these (...) conclusions. (shrink)

This paper offers a critical survey and analysis of empirical studies on creativity, with emphasis on how imagination plays a role in the creative process. It takes as a foil the romantic view that, given features like novelty, incubation, and insight, we should be skeptical about the prospects for naturalistic explanation of creativity. It rebuts this skepticism by first distinguishing stages or operations in the creative process. It then works through various behavioral and neural studies, and corresponding philosophical theorizing, that (...) concern the preparation, generation, insight, and evaluation stages of creative processes. The result is not a complete explanation of creativity, but it identifies an explanatory path towards such an explanation, including the features of creativity that motivate that skepticism.

The aim of this paper is to discuss a seemingly straightforward argument against physicalism which, despite being implicit in much of the philosophical debate about consciousness, has not received the attention it deserves (compared to other, better-known “epistemic”, “modal”, and “conceivability” arguments). This is the argument from the non-supervenience of the first-personal (and indexical) facts on the third-personal (and non-indexical) ones. This non-supervenience, together with the assumption that the physical facts (as conventionally understood) are third-personal, entails that some facts – (...) namely, first-personal, phenomenal ones – do not supervene on the physical facts. Unlike other arguments against physicalism, the first-personal argument, if successful, refutes not only physicalism but also other third-personal metaphysical pictures, including standard versions of dualism.

Concerns about the efficacy of consciousness can arise either as part of a broad concern about the efficacy of mentality in general, or as a more specific worry focusing on conscious mental states, or the conscious aspects of mental states. This chapter discusses in detail why the two issues, the general one concerning the mental, and the more specific issue about consciousness, have come to be distinguished and how they relate to each other. It discusses the epiphenomenalist arguments of the (...) nineteenth‐century biologist T. H. The experiments and observations that moved Huxley to embrace epiphenomenalism were basically of the following sort: animals for which we have compelling anatomical evidence that they are not conscious can perform activities of the kind that we normally take to require consciousness. The epiphenomenalist arguments follow only on the assumption that the mental is not reducible to the physical; namely, the assumption that reductionist physicalism has been ruled out. (shrink)

What is possible, according to the empiricist conception, is what our evidence positively allows; and what is necessary is what it compels. These notions, along with logical possibility, are the only defensible notions of possibility and necessity. In so far as nomic and metaphysical possibilities are defensible, they fall within empirical possibility. These empirical conceptions are incompatible with traditional possible world semantics. Empirically necessary propositions cannot be defined as those true in all possible worlds. There can be empirical possibilities without (...) empirical necessities. The duality of possibility and necessity can be degenerate and can even be falsified. (shrink)
