Perceiving External Things and the Time‐Lag Argument

Abstract: We seem to directly perceive external things. But can we? According to the time‐lag argument, we cannot. What we directly perceive happens now. There is a time‐lag between our perceptions and the external things we seem to directly perceive; these external things happen in the past; thus, what we directly perceive must be something else, for example, sense‐data, and we can only at best indirectly perceive other things. This paper examines the time‐lag argument given contemporary metaphysics. I argue that this argument is not as compelling as it may initially seem. First, it denies that what we directly perceive can ever be what it seems to be; second, it conflicts with the current physical conception of time, relativity theory. This latter point leads to a more general one: the argument's force depends on a particular metaphysical conception on time, presentism, which is controversial in contemporary metaphysics of time. Given the alternative conception, eternalism, the argument is much less compelling. The overall argument of this paper, then, is that, if one wishes to hold that we directly perceive external things, we should subscribe to the latter view of time, i.e., eternalism.     

Brown on Mackie: Echoes of the Lottery Paradox

In “The possibility of morality,” Phil Brown considers whether moral error theory is best understood as a necessary or contingent thesis. Among other things, Brown contends that the argument from relativity, offered by John Mackie—error theory’s progenitor—supports a stronger modal reading of error theory. His argument is as follows: Mackie’s is an abductive argument that error theory is the best explanation for divergence in moral practices. Since error theory will likewise be the best explanation for similar divergences in possible worlds similar to our own, we may conclude that error theory is true at all such worlds, just as it is in the actual world. I contend that Brown’s argument must fail, as abductive arguments cannot support the modal conclusions he suggests. I then consider why this is the case, concluding that Brown has stumbled upon new and interesting evidence that agglomerating one’s beliefs can be epistemically problematic—an issue associated most famously with Henry Kyburg’s lottery paradox.     

Time without Rate

There is a lingering objection to the idea of the passage of time. Roughly speaking, the argument runs as follows: (i) if time passes, its passage must occur at some rate, but (ii) there is no such rate; hence, the passage of time is a myth. While some philosophers try to reject premise (ii), I wish to challenge the first premise by arguing that time may pass with or without a rate. My argument addresses two cases, one that identifies the passage of time with changes in things and one that does not. I call the former view ‘the Priorian passage theory’, and the latter view ‘the pure passage theory’. I argue that each dynamic view of time is immune to the rate argument. Further, I suggest a possible extension of the Priorian passage theory, in which the passage of time is identified with the pure persistence of things.     

A mereological argument for the non‐spatiotemporality of things in themselves

Kant's published arguments for the non‐spatiotemporality of things in themselves have not been well received. I argue that Kant has available to himself an argument for the non‐spatiotemporality of things in themselves that is premised upon a disparity between the compositional structure of the intelligible world and the structure of space and time. I argue that Kant was unwaveringly committed to the premises of this argument throughout his career and that he was aware of their idealistic implications. I also argue that this argument is consistent with Kant's restrictive mature epistemology. If my argument is successful, then even if Kant's published arguments for transcendental idealism fail, we need not regard his ambitious metaphysical project as a failure.     

Why Simpler Arguments are Better

In this paper, I argue that, other things being equal, simpler arguments are better. In other words, I argue that, other things being equal, it is rational to prefer simpler arguments over less simple ones. I sketch three arguments in support of this claim: an argument from mathematical proofs, an argument from scientific theories, and an argument from the conjunction rule.     

Ned Block,Wittgenstein, and the Inverted Spectrum

In ‘Wittgenstein and Qualia’ Ned Block argues for the existence of inverted spectra and those ineffable things, qualia. The essence of his discussion is a would-be proof, presented through a series of pictures, of the possible existence of an inverted spectrum. His argument appeals to some remarks by Wittgenstein which, Block holds, commit the former to a certain ‘dangerous scenario’ wherein inverted spectra, and consequently qualia live and breath. I hold that a key premise of this proof is incoherent. Furthermore, Block’s dangerous scenario does not follow from Wittgenstein’s innocent one, as Block believes it does, but rather is in conflict with it.     

The Metamathematics of Putnam’s Model-Theoretic Arguments

Putnam famously attempted to use model theory to draw metaphysical conclusions. His Skolemisation argument sought to show metaphysical realists that their favourite theories have countable models. His permutation argument sought to show that they have permuted models. His constructivisation argument sought to show that any empirical evidence is compatible with the Axiom of Constructibility. Here, I examine the metamathematics of all three model-theoretic arguments, and I argue against Bays (2001, 2007) that Putnam is largely immune to metamathematical challenges.     

The Humdrum of Rhetorics: A Reply to Durrheim's "Theoretical Conundrum"

Durrheim's core argument appears upon close inspection not to be very convincing, nor his use of rhetoric. His argument is now shown from the—presumably exemplary—four theories, he cites. He unwarrantly strengthens his argument by preselection, overgeneralization, oversimplification, and by confusing and misconceiving key concepts, and using an arbitrary selection of theories. His suggestion that he knows the vast literature of authoritarianism is not substantiated, considering the unbalanced use of citations, some along the line of Jaensch, Ray and Eysenck. Rhetoric is portrayed as an alternative scientific method, but seems in this way rather to regress into a neodogmatic approach devoid of empirical testing and emancipatory content.     

A Deranged Argument Against Public Languages

Are there really such things as public languages? Are things like English and Urdu mere myths? I urge that, despite an intriguing line of thought which may be extracted from Davidson’s ‘A Nice Derangement of Epitaphs’, philosophers are right to countenance such things in their final ontology. The argument rebutted, which I concede may not have been one which Davidson himself ultimately embraced, is that knowledge of a public language is neither necessary nor sufficient for successful conversational interaction, so that such shared languages are explanatorily otiose. In particular, the ability of interlocutors to communicate in the face of linguistic novelty and error seems to support this conclusion. I respond with two main points. First, initial impressions aside, knowledge of things like English and Urdu is explanatorily necessary. Second, even if successful conversation could be explained without positing such knowledge, we have other reasons to take public languages ontologically seriously. The ultimate result is that what I label a ‘deranged argument against public languages’ is unsound.     

Con-reasons and the causal theory of action

A con-reason is a reason which plays a role in motivating and explaining an agent's behaviour, but which the agent takes to count against the course of action taken. Most accounts of motivating reasons in the philosophy of action do not allow such things to exist. In this essay, I pursue two aims. First, I argue that, whatever metaphysical story we tell about the relation between motivating reasons and action, con-reasons need to be acknowledged, as they play an explanatory role not played by pro-reasons (the reason the agent takes to count in favour of the action taken). Second, I respond to an argument recently developed by David-Hillel Ruben to the effect that a causal theory of action – still known as ‘the standard story’ – cannot account for con-reasons. His argument attempts to show that a fundamental principle of the causal theory cannot be reconciled with the role con-reasons play in a certain kind of imagined case. I first argue that a causal theorist is not, in fact, committed to the problematic principle; this argument has an added benefit, since the principle has been taken by many to show that the causal theory generates a puzzle about the possibility of weak-willed action. I then argue that a causal theorist has good reason to reject the possibility of Ruben's imagined cases. If successful, my arguments make clearer the commitments of the causal theory and show that it can accommodate con-reasons in the way I think they ought to be accommodated.     

Van Inwagen and the Quine-Putnam indispensability argument

In this paper I do two things: (1) I support the claim that there is still some confusion about just what the Quine-Putnam indispensability argument is and the way it employs Quinean meta-ontology and (2) I try to dispel some of this confusion by presenting the argument in a way which reveals its important meta-ontological features, and include these features explicitly as premises. As a means to these ends, I compare Peter van Inwagen’s argument for the existence of properties with Putnam’s presentation of the indispensability argument. Van Inwagen’s argument is a classic exercise in Quinean meta-ontology and yet he claims – despite his argument’s conspicuous similarities to the Quine-Putnam argument – that his own has a substantially different form. I argue, however, that there is no such difference between these two arguments even at a very high level of specificity; I show that there is a detailed generic indispensability argument that captures the single form of both. The arguments are identical in every way except for the kind of objects they argue for – an irrelevant difference for my purposes. Furthermore, Putnam’s and van Inwagen’s presentations make an assumption that is often mistakenly taken to be an important feature of the Quine-Putnam argument. Yet this assumption is only the implicit backdrop against which the argument is typically presented. This last point is brought into sharper relief by the fact that van Inwagen’s list of the four nominalistic responses to his argument is too short. His list is missing an important – and historically popular – fifth option.

Smith On Times And Tokens

In this essay I respond to Quentin Smith's chargethat `the date-analysis version ofthe tenseless theory of time cannot give adequateaccounts of the truth conditions ofthe statements made by tensed sentence-tokens'(Smith 1999, 236). His argument isbased on an analysis of certain counterfactualsituations that is at odds with thedate-analysis account of language and hence succeedsonly in begging the questionagainst that theory. To anticipate: his argumentfails if one allows that temporalindexicals such as `now' rigidly designate theirtime of utterance, something thedate-analyst can happily admit whether she adheresto an absolute or relationalmetaphysics of time.     

God's point of view: A reply to Mander

According to one antitheist argument, God cannot know what it is like to be me because He, who is necessarily unlimited and necessarily incorporeal, cannot have my point of view. In his recent article, William J. Mander tries to demonstrate that God can indeed have His own point of view and my point of view at the same time by providing examples that seem to motivate his claim. I argue that none of his examples succeeds in this task. I introduce a different objection to the antitheist argument that appeals to the Thomistic principle regarding divine attributes.     

Stoicism, Evil, and the Possibility of Morality

Martha Nussbaum's work has been characterized by a sustained critique of Stoic ethics, insofar as that ethics denies the validity and importance of our valuing things that elude our control. This essay explores the idea that the very possibility of morality, understood as social or interpersonal ethics, presupposes that we do value such things. If my argument is right, Stoic ethics is unable to recognize the validity of morality (so understood) but can at most acknowledge duties to oneself. A further implication is that moral luck, so far from undermining morality as some have held, is presupposed by the very possibility of morality.     

Book Reviews

Subjective measures of well-being—measures based on answers to questions such as ‘Taking things all together, how would you say things are these days—would you say you're very happy, pretty happy, or not too happy these days?’—are often presented as superior to more traditional economic welfare measures, e.g., for public policy purposes. This paper aims to spell out and assess what I will call the argument from directness: the notion that subjective measures of well-being better represent well-being than economic measures do because subjective measures (and subjective measures alone) are direct measures of well-being. My main thesis is that the argument begs the question against proponents of economic measures: it is based on a premise that they reject and that is no less in need of justification than the conclusion of the argument, namely, the proposition that well-being is constituted by subjectively experienced mental states. If subjective measures can be defended as valid measures of well-being at all, I will maintain, it is because they are (imperfect) indirect measures of well-being.     

Plantinga's Probability Arguments Against Evolutionary Naturalism

In Chapter 12 of Warrant and Proper Function , Alvin Plantinga constructs two arguments against evolutionary naturalism, which he construes as a conjunction E&N . The hypothesis E says that "human cognitive faculties arose by way of the mechanisms to which contemporary evolutionary thought directs our attention" (p. 220). With respect to proposition N , Plantinga (p. 270) says "it isn't easy to say precisely what naturalism is," but then adds that "crucial to metaphysical naturalism, of course, is the view that there is no such person as the God of traditional theism." Plantinga tries to cast doubt on the conjunction E&N in two ways. His "preliminary argument" aims to show that the conjunction is probably false, given the fact ( R ) that our psychological mechanisms for forming beliefs about the world are generally reliable. His "main argument" aims to show that the conjunction E&N is self-defeating – if you believe E&N , then you should stop believing that conjunction. Plantinga further develops the main argument in his unpublished paper "Naturalism Defeated" (Plantinga 1994). We will try to show that both arguments contain serious errors.     

Maximality and Microphysical Supervenience

A property, F, is maximal iff, roughly, large parts of an F are not themselves Fs. Maximal properties are typically extrinsic, for their instantiation by x depends on what larger things x is part of. This makes trouble for a recent argument against microphysical supervenience by Trenton Merrick's. The argument assumes that consciousness is an intrinsic property, whereas consciousness is in fact maximal and extrinsic.     

Representing Bodies

According to the bodily awareness thesis (BAT), awareness of one's own body is a necessary condition for the acquisition and possession of concepts of primary qualities such as force and shape. I discuss two arguments for this thesis. The acquisition argument for BAT focuses on the role of bodily sensation and action in the acquisition of the concept of force. I suggest that this argument requires us to conceive of the content of sensation as both representational and non–conceptual. The objective reality argument for BAT claims that awareness of one's own body is an essential component of those experiences which are required for a proper grasp of concepts of primary qualities. I conclude by arguing, in opposition to Sartre and Merleau–Ponty, that there is no incoherence in the idea that one's body is a thing among other things.
