    What Time-travel Teaches Us About Future-Bias
    Philosophies 6 (38): 38. 2021.
    Future-biased individuals systematically prefer positively valenced events to be in the future (positive future-bias) and negatively valenced events to be in the past (negative future-bias). The most extreme form of future-bias is absolute future-bias, whereby we completely discount the value of past events when forming our preferences. Various authors have thought that we are absolutely future-biased (Sullivan (2018:58); Parfit (1984:173) and that future-bias (absolute or otherwise) is at least…Read more

    Deflationists hold that it does not seem to us, in experience, as though time robustly passes. There is some recent empirical evidence that appears to support this contention. Equally, empirical evidence suggests that we naïvely represent time as dynamical. Thus deflationists are faced with an explanatory burden. If, as they maintain, the world seems to us in experience as though it is non-dynamical, then why do we represent time as dynamical? This paper takes up the challenge of investigating, …Read more

    Tensed Facts and the Fittingness of our Attitudes 1
    Philosophical Perspectives 36 (1): 216-232. 2022.
    We direct different attitudes towards states of affairs depending on where in time those states of affairs are located. Call this the type asymmetry. The type asymmetry appears fitting. For instance, it seems fitting to feel guilt or regret only about states of affairs that are past, and anticipation only of states of affairs that are future. It has been argued that the type asymmetry could only be fitting if there are tensed facts, and hence that since it is fitting, there are tensed facts. In …Read more

    Locating Temporal Passage in a Block World
    Ergo: An Open Access Journal of Philosophy 10 (n/a). 2023.
    This paper aims to determine whether we can locate temporal passage in a non-dynamical (block universe) world. In particular, we seek to determine both whether temporal passage can be located somewhere in our world if it is non-dynamical, and also to home in on where in such a world temporal passage can be located, if it can be located anywhere. We investigate this question by seeking to determine, across three experiments, whether the folk concept of temporal passage can be satisfied in our wor…Read more

    People are ‘biased toward the future’: all else being equal, we typically prefer to have positive experiences in the future, and negative experiences in the past. Several explanations have been suggested for this pattern of preferences. Adjudicating among these explanations can, among other things, shed light on the rationality of future-bias: For instance, if our preferences are explained by unjustified beliefs or an illusory phenomenology, we might conclude that they are irrational. This paper…Read more

    The Triviality Argument against presentism maintains that we should reject presentism because there is no way to define the view that is not either trivially true or obviously false. We suggest that this style of argument over-emphasises purely linguistic means of representing a philosophical thesis. We argue that there is no reason to suppose that all philosophical theses must be linguistically representable, and thus that the failure to linguistically represent presentism is no big deal. It ce…Read more

    If Time Can Pass, Time Can Pass at Different Rates
    Analytic Philosophy 62 (1): 21-32. 2019.
    According to the No Alternate Possibilities argument, if time passes then the rate at which it passes could be different. Thus, time cannot pass, since if time passes, then necessarily it passes at a rate of 1 second per second. One response to this argument is to posit hypertime, and to argue that at different worlds, time passes at different rates when measured against hypertime. Since many A-theorists think we can make sense of temporal passage without positing hypertime, we pursue a differen…Read more

    Time is woven into the fabric of our lives. Everything we do, we do in and across time. It is not just that our lives are stretched out in time, from the moment of birth to the moment of our death. It is that our lives are stories. We make sense of ourselves, today, by understanding who we were yesterday, and the day before, and the day before that; by understanding what we did and why we did it. Our memories shape our present selves, since we are the product of who we were, and who we remember …Read more

    Temporal dynamists typically hold that it seems to us as though time robustly passes, and that its seeming so is explained by the fact that time does robustly pass. Temporal non-dynamists hold that time does not robustly pass. Some non-dynamists nevertheless hold that it seems as though it does: we have an illusory phenomenal state whose content represents robust passage. Call these phenomenal passage illusionists. Other non-dynamists argue that the phenomenal state in question is veridical, and…Read more

    We argue that, insofar as one accepts either supersubstantivalism or strong composition as identity for the usual reasons, one has (defeasible) reasons to accept the other as well. Thus, all else being equal, one ought to find the package that combines both views—the Identity Package—more attractive than any rival package that includes one, but not the other, of either supersubstantivalism or composition as identity.

    What is temporal error theory?
    Philosophical Studies 172 (9): 2427-2444. 2015.
    Much current debate in the metaphysics of time is between A-theorists and B-theorists. Central to this debate is the assumption that time exists and that the task of metaphysics is to catalogue time’s features. Relatively little consideration has been given to an error theory about time. Since there is very little extant work on temporal error theory the goal of this paper is simply to lay the groundwork to allow future discussion of the relative merits of such a view. The paper thus develops a …Read more

    Causation Sans Time
    with Sam Baron
    American Philosophical Quarterly 52 (1): 27-40. 2015.
    Is time necessary for causation? We argue that, given a counterfactual theory of causation, it is not. We defend this claim by considering cases of counterfactual dependence in quantum mechanics. These cases involve laws of nature that govern entanglement. These laws make possible the evaluation of causal counterfactuals between space-like separated entangled particles. There is, for the proponent of a counterfactual theory of causation, a possible world in which causation but not time exists th…Read more

    Why are people so darn past biased?
    In Christoph Hoerl, Teresa McCormack & Alison Fernandes (eds.), Temporal Asymmetries in Philosophy and Psychology., Oxford University Press. pp. 139-154. 2022.
    Many philosophers have assumed that our preferences regarding hedonic events exhibit a bias toward the future: we prefer positive experiences to be in our future and negative experiences to be in our past. Recent experimental work by Greene et al. (ms) confirmed this assumption. However, they noted a potential for some participants to respond in a deviant manner, and hence for their methodology to underestimate the percentage of people who are time neutral, and overestimate the percentage who ar…Read more

    This book advertises itself as an exploration of the world-time parallel, that is, the parallel between the modal dimension, on the one hand, and the temporal dimension, on the other. It is that, and much more. As the authors point out, there is reasonable agreement that we can model times, through temporal logic, in ways that are analogous to those by which we model modality through the logic of possible worlds. But this formal parallel has almost universally been taken to be a merely formal pa…Read more

    Assessor Relative Conativism
    Journal of the American Philosophical Association 10 (1): 96-115. 2024.
    According to conventionalist or conativist views about personal-identity, utterances of personal-identity sentences express propositions that are, in part, made true by the conative attitudes of relevant persons-stages. In this paper I introduce assessor relative conativism: the view that a personal-identity proposition can be true when evaluated at one person-stage's context and false when evaluated at another person-stage's context, because person-stages have different patterns of conative att…Read more

    Prudence and Perdurance
    In Karen Bennett & Dean Zimmerman (eds.), Oxford Studies In Metaphysics, Oup. forthcoming.
    Many philosophers are sympathetic to a perdurantist view of persistence. One challenge facing this view lies in its ability to ground prudential rationality. If, as many have thought, numerical identity over time is required to ground there being sui generis (i.e. non-instrumental) prudential reasons, then perdurantists can appeal only to instrumental reasons. The problem is that it is hard to see how, by appealing only to instrumental reasons, the perdurantist can vindicate the axiom of prudenc…Read more

    A Blast From The Past
    The Philosophers' Magazine 77 82-86. 2017.
    That we find the idea of travelling in time, and in particular travelling backwards in time, fascinating, is evidenced by the plethora of new science fictions shows depicting time travel that hit our TV screens in 2016. I love time travel shows, and I can hardly keep up. In almost all cases these shows depict what philosophers call inconsistent time travel stories: stories that commit what my colleague Nick Smith (The University of Sydney) calls the second time around fallacy. These stories dep…Read more

    It is often supposed that metaphysical explanation is asymmetric: that for all x and y, if x metaphysically explains y, then y does not metaphysically explain x. Even amongst those who hold that metaphysical explanation is not asymmetric, but nonsymmetric, it is assumed that a relatively small number of particular explanations are symmetric: by and large, if x metaphysically explains y, then y does not metaphysically explain x. Both parties agree that as a matter of fact we at least typically ju…Read more

    Empirical evidence shows that people have multiple time-biases. One is near-bias; another is future-bias. Philosophical theorising about these biases often proceeds on two assumptions. First, that the two biases are _independent_: that they are explained by different factors (the independence assumption). Second, that there is a normative asymmetry between the two biases: one is rationally impermissible (near-bias) and the other rationally permissible (future-bias). The former assumption at leas…Read more

    The harmony of grounding
    with Sam Baron and Jonathan Tallant
    Philosophical Studies 179 (11): 3421-3446. 2022.
    Mereological harmony is the idea that the mereological structure of objects mirrors the mereological structure of locations. Grounding harmony is the idea that there is a similar mirroring between the grounding structure of objects and locations. Our goal in this paper is exploratory: we introduce and then explore two notions of grounding harmony: locative and structural. We outline potential locative and structural harmony principles for grounding, and show which of these principles may entail,…Read more

    On the concept of sexual perversion
    Philosophical Quarterly 60 (241): 808-830. 2010.
    Why has little progress been made in resolving the debate about the concept of sexual perversion? I suggest that the stalemate is due to misunderstandings and poor methodology. I develop a new methodology for resolving disputes about the correct analysis of the contents of concepts where the disputes have social and political ramifications. When deciding between competing analyses of a concept, we should not just consider facts about our inferential and judgemental dispositions with respect to t…Read more

    On Contingently Error-theoretic Concepts
    American Philosophical Quarterly 47 (2): 181-190. 2010.
    An error theorist about a particular discourse combines the cognitivist thesis that the discourse is truth-apt with the thesis that core statements asserted by the discourse are false. For instance, one is an error theorist about witch discourse if one thinks that witch discourse is truth-apt and that some of the entities and properties quantified over by core statements in the discourse, namely witches and magical powers, do not exist and hence that certain core statements of the discourse are …Read more

    I argue that two competing accounts of persistence, three and four dimensionalism, are in fact metaphysically equivalent. I begin by clearly defining three and four dimensionalism, and then I show that the two theories are intertranslatable and equally simple. Through consideration of a number of different cases where intuitions about persistence are contradictory, I then go on to show that both theories describe these cases in the same manner. Further consideration of some empirical issues aris…Read more

    Many philosophers have become sceptical of the use of thought experiments in theorising about personal identity. In large part this is due to work in experimental philosophy that appears to confirm long held philosophical suspicions that thought experiments elicit inconsistent judgements about personal identity, and hence judgements that are thought to be the product of cognitive biases. If so, these judgements appear to be useless at informing our theories of personal identity. Using the method…Read more

    This paper proffers an account of why interdisciplinary research on, inter alia, the nature of time can be fruitful even if the disciplines in question have different explanatory projects. We suggest that the special sciences perform a subject setting role for lower-level disciplines such as physics. In essence, they tell us where, amongst a theory of the physical world, we should expect to locate phenomena such as temporality; they tell us what it would take for there to be time. Physical theo…Read more

    Decifrare il convenzionalismo dell'identità personale
    Rivista di Estetica 41 59-83. 2009.
    Conventionalism’ about personal-identity is an umbrella term for a cluster of views. All these views accept the core idea that conventions, or what are often known as person-directed practices, are crucially involved in the identity of persons over time, and that had those conventions or practices been different, the individuation and persistence conditions of persons would have been different.The purpose of this paper is not to argue for conventionalism broadly understood, nor for any particula…Read more

    Causation in a timeless world
    with Sam Baron
    Synthese 191 (12): 2867-2886. 2014.
    This paper offers a new way to evaluate counterfactual conditionals on the supposition that actually, there is no time. We then parlay this method of evaluation into a way of evaluating causal claims. Our primary aim is to preserve, at a minimum, the assertibility of certain counterfactual and causal claims once time has been excised from reality. This is an important first step in a more general reconstruction project that has two important components. First, recovering our ordinary language cl…Read more

    From Timeless Physical Theory to Timelessness
    with Samuel Baron and Peter Evans
    Humana Mente 4 (13): 35-59. 2010.
    This paper addresses the extent to which both Julian Barbour‘s Machian formulation of general relativity and his interpretation of canonical quantum gravity can be called timeless. We differentiate two types of timelessness in Barbour‘s (1994a, 1994b and 1999c). We argue that Barbour‘s metaphysical contention that ours is a timeless world is crucially lacking an account of the essential features of time—an account of what features our world would need to have if it were to count as being one in …Read more

    Sparse Parts
    Sorites 17 31-48. 2006.
    Four dimensionalism, the thesis that persisting objects are four dimensional and thus extended in time as well as space, has become a serious contender as an account of persistence. While many four dimensionalists are mereological universalists, there are those who find mereological universalism both counterintuitive and ontologically profligate. It would be nice then, if there was a coherent and plausible version of four dimensionalism that was non-universalist in nature. I argue that unfortuna…Read more

    Global directional eliminativists deny that there is any global direction to time. This paper provides a way to understand everyday temporal assertions—assertions made outside the physics or metaphysics rooms, the truth of which appears to require that time has a global direction—on the assumption that global directional eliminativism is true.
