PRESENTISM,TRUTH AND SUPERVENIENCE

Truthmaker theory is commonly thought to pose a challenge for presentism. Presentism seems to lack the ontological and ideological resources required to adequately underwrite the truth of propositions concerning the past. That is because if presentism is true, then the past does not exist. According to the standard response to this challenge, the truth of propositions concerning the past supervenes on surrogate entities that ‘stand proxy’ for past things. I argue that in order for the standard response to the truthmaker challenge to succeed these surrogate entities must stand in necessary connections to the past. I go on to argue that because the standard response is already committed to denying the existence of cross‐temporal modal connections of this kind, by its own lights that response is in error. 1     

A thousand pleasures are not worth a single pain: The compensation argument for Schopenhauer's pessimism

Pessimism is, roughly, the view that life is not worth living. In chapter 46 of the second volume of The World as Will and Representation, Arthur Schopenhauer provides an oft‐neglected argument for this view. The argument is that a life is worth living only if it does not contain any uncompensated evils; but since all our lives happen to contain such evils, none of them are worth living. The now standard interpretation of this argument (endorsed by Kuno Fischer and Christopher Janaway) proceeds from the claim that the value—or rather valuelessness—of life's goods makes compensation impossible. But this interpretation is neither philosophically attractive nor faithful to the text. In this article, I develop and defend an alternative interpretation (suggested by Wilhelm Windelband and Mark Migotti) according to which it is instead the actual temporal arrangement of life's goods and evils that makes compensation impossible.     

Temporal necessity and the conditional

In [12] Richmond Thomason and Anil Gupta investigate a semantics for conditional logic that combines the ideas of [8] and [9] with a branching time model of tense logic. The resulting branching time semantics for the conditional is intended to capture the logical relationship between temporal necessity and the conditional. The central principle of this logical relationship is Past Predominance, according to which past similarities and differences take priority over future similarities and differences in determining the comparative similarity of alternative possible histories with respect to a given present moment.In this paper I will use ordinary possible worlds semantics (i.e. Kripke frames) to solve the completeness problem for a system of logic that combines conditional logic with temporal necessity in the context of Past Predominance. Branching time models turn out not to be necessary for the articulation of Past Predominance, and this means that one can axiomatize Past Predominance without first having to solve a much more difficult problem: the completeness problem for the logic of temporal necessity in the context of branching time.Thomason and Gupta argue in [12] that in addition to Past Predominance, temporal necessity and the conditional are logically related, by what have become known as the Edelberg Inferences, whose apparent validity motivates the very complicated theory presented at the end of [12]. I will conclude this paper by examining how the Edelberg inferences would be incorporated into the possible worlds based system presented in the earlier sections of this paper.This article is based on the second chapter of my doctoral dissertation Studies in the Semantics of Modality, University of Pittsburgh, 1985. I thank my adviser Richmond Thomason for his patient help throughout the course of that project.     

Search for multiple targets: Evidence for memory-based control of attention

There are two opposing models with regard to the function of memory in visual search: a memorydriven model and a memory-free model. Recently, Horowitz and Wolfe (2001) investigated a multipletarget search task. Participants were required to decide whether or not there were at leastn targets present. They demonstrated that the reaction time ×n function has a positive and accelerated curve. They argued that the memory-free model predicts this curve, whereas the memory-driven model predicts a linear function. In this study, I varied the total set sizes of a multiple-target search task and fitted the models separately for eachn condition. The model fit indicated that the memory-driven model is more appropriate than the memory-free model in eachn condition. These results suggest that an amnesic process does not cause the positive accelerated curve of the reaction time ×n function but that it is the result of the time needed to examine each additionaln item.     

Tensed Supervenience: A No‐Go for Presentism

Recent attempts to resolve the truthmaker objection to presentism employ a fundamentally tensed account of the relationship between truth and being. On this view, the truth of a proposition concerning the past supervenes on how things are, in the present, along with how things were, in the past. This tensed approach to truthmaking arises in response to pressure placed on presentists to abandon the standard response to the truthmaker objection, whereby one invokes presently existing entities as the supervenience base for the truth of past‐directed propositions. In this paper, I argue that a fundamentally tensed approach to truthmaking is implausible because it requires the existence of cross‐temporal supervenience relations, which are anathema to presentism.     

The puzzle of hyper‐change

If there is a second dimension of time – a so‐called ‘hypertime’ – is it logically possible for the past to change? Some have said yes; others have said no. I say yes provided that one has the appropriate ontological view of hypertime. So far, the ontology of hypertime has seldom been discussed. As such, this paper not only defends the logical possibility of a changing past, but aims to start a discussion on what ontological commitments are required to make sense of a changing past.     

Indeterminism, Explanation, and Luck

I first adumbrate pertinent aspectsof Robert Kane's libertarian theory of free choice oraction and an objection of luck that has been levelledagainst the theory. I then consider Kane's recentresponses to this objection. To meet these responses,I argue that the view that undetermined choices (ofthe sort implied by Kane's theory) are a matter ofluck is associated with a view about actionexplanation, to wit: when Jones does A and hisdoing of A is undetermined, and when hiscounterpart, Jones*, in the nearest possibleworld in which the past and the laws are held constantuntil the moment of choice does B instead, thereis no explanation (deterministic or indeterministic)of the difference in outcome – Jones's A-ing butJones*'s B-ing – in terms of prior reasonsor motives of either agent. Absence of such anexplanation is one crucial factor that underliesthe charge that Jones's A-ing and Jones*'sB-ing are matters of luck. I argue that thissort of luck is incompatible with responsibility.     

Temporal necessity; Hard facts/soft facts

Conclusion In conclusion, then, the notion of temporal necessity is certainly queer and perhaps a misnomer. It really has little to do with temporality per se and everything to do with counterfactual openness or closedness. We have seen that the future is as unalterable as the past, but that this purely logical truth is not antithetical to freedom or contingency. Moreover, we have found certain past facts are counterfactually open in that were future events or actualities to be other than they will be, these past facts would have been different as a consequence. God's beliefs about the future are such past facts. Moreover, the effects of actions which God would have taken had He believed differently are also such past facts. Oddly enough, then, virtually any past fact is potentially counterfactually open, and the only necessity that remains is purely de facto. We, of course, do not in general know which events of the past depend counterfactually on present actions, and those cases we do know about seem rather trivial. Our intuitions of the necessity, unalterability, and unpreventability of the past as opposed to the future stem from the impossibility of backward causation, which is precluded by the dynamic nature of time and becoming. But the counterfactual dependence of God's beliefs on future events or actualities is not a case of backward causation: rather future-tense propositions are true in virtue of what will happen, given a view of truth as correspondence, and God simply has the essential property of knowing all and only true propositions. With regard to the future, virtually all facts are counterfactually open, and therefore future-tense propositions are not temporally necessary. Propositions thus move from being temporally contingent to being temporally necessary when all the opportunities to affect things counterfactually have slipped by. Hence, the mere fact that an event is past is no indication that it is counterfactually closed. This is especially evident in the case of God's foreknowledge. If we say that God foreknows that I shall do x and therefore I cannot refrain from doing x, lest I change God's past foreknowledge, we are being deceived by a modality which has nothing to do with my power or freedom. All that is impossible is the conjunction of God's foreknowledge that p and of ~ p; but this modality in sensu composito has no bearing on my ability to act such that ~ p would be true and God would have foreknown differently. Temporal necessity, then, turns out to be only obliquely temporal and modally weak, certainly no threat to freedom or divine foreknowledge.     

An infinite temporal regress is compatible with the <Emphasis Type="Italic">Doctrine of Creatio Originans</Emphasis>

In this paper I show that the existence of an infinite temporal regress does not undermine the soundness of Craigs version of the Kalam Cosmological Argument. To this end I shall focus on a particular complication that Craig raises against one of his arguments in support of a finite temporal regress. I will show that this complication can be made innocuous by extending the notion of A-theoretic time, which is presupposed by Craigs argument, to include a notion of temporal becoming that is compatible with the existence of an infinite regress of temporal events. All this shows that God could have created an infinite temporal regress a finite time in the past without this entailing a contradiction.     

Desire-satisfaction and Welfare as Temporal

Welfare is at least occasionally a temporal phenomenon: welfare benefits befall me at certain times. But this fact seems to present a problem for a desire-satisfaction view. Assume that I desire, at 10am, January 12th, 2010, to climb Mount Everest sometime during 2012. Also assume, however, that during 2011, my desires undergo a shift: I no longer desire to climb Mount Everest during 2012. In fact, I develop an aversion to so doing. Imagine, however, that despite my aversion, I am forced to climb Mount Everest. Does climbing Mount Everest benefit me? If so, when? A natural answer seems to be that if in fact it does benefit me, it benefits me at no particular time, and hence the desire-satisfaction view cannot accommodate the phenomenon of temporal welfare. In this paper, I argue, first, that a desire-satisfaction view can accommodate the phenomenon of temporal welfare only by accepting what I call the “time-of-desire” view: that p benefits x at t only if x desires p at t. Second, I argue that this view can be defended from important objections.     

The Formulation of Epistemological Disjunctivism

I argue that we should question the orthodox way of thinking about epistemological disjunctivism. I suggest that we can formulate epistemological disjunctivism in terms of states of seeing things as opposed to states of seeing that p. Not only does this alternative formulation capture the core aspects of epistemological disjunctivism as standardly formulated, it has two salient advantages. First, it avoids a crucial problem that arises for a standard formulation of epistemological disjunctivism—the basis problem. And second, it is less committed than standard formulations are in the metaphysics of perception.     

Cosmic inflation and the past hypothesis

The past hypothesis is that the entropy of the universe was very low in the distant past. It is put forward to explain the entropic arrow of time but it has been suggested (e.g. [Penrose, R. (1989a). The emperor’s new mind. London:Vintage Books; Penrose, R. (1989b). Annals of the New York Academy of Sciences, 571, 249–264; Price, H. (1995). In S. F. Savitt (Ed.), Times’s arrows today. Cambridge: Cambridge University Press; Price, H. (1996). Time’s arrow and Archimedes’ point. Oxford: Oxford University Press; Price, H. (2004). In C. Hitchcock (Ed.), Contemporary debates in philosophy of science. Oxford: Blackwell]) that it is itself in need of explanation. It has also been suggested that cosmic inflation could provide the explanation, but Price (2004) raises a serious objection to this suggestion, which has otherwise received very little attention in the philosophical literature. Price points out that the standard inflationary explanation involves a double standard: although the evolution of the universe described by the inflationary model seems natural from the standard temporal perspective it looks highly unnatural from the reversed temporal perspective. The main purpose of this paper is to propose a novel form of the inflationary explanation that avoids this objection. It is argued that the inflationary model would not involve a double standard (but would still explain the past hypothesis) if we construct the model with a global “boundary” condition instead of a conventional boundary condition: if we assume that the universe is as generic as possible overall, rather than as generic as possible at some given point (e.g. the Big Bang) as is assumed in the standard inflationary model. This novel form of the inflationary explanation is then compared with Price’s 1996 preferred explanation, a version of the so-called “Weyl hypothesis”.     

The Causal Efficiency of the Passage of Time

Does mere passage of time have causal powers? Are properties like ??being n days past?? causally efficient? A pervasive intuition among metaphysicians seems to be that they don??t. Events and/or objects change, and they cause or are caused by other events and/or objects; but one does not see how just the mere passage of time could cause any difference in the world. In this paper, I shall discuss a case where it seems that mere passage of time does have causal powers: Sydney Shoemaker??s (1969) possible world where temporal vacua (allegedly) take place. I shall argue that Shoemaker??s thought-experiment doesn??t really aim at teaching us that there can be time without change, but rather that if such a scenario is plausible at all (as I think it is) it provides us with good reasons to think that mere passage of time can be directly causally efficient.     

CARRYING THE BURDEN OF PAST VIOLENCES

Through a comparative study of two Palestinian transnational youth movements, this article seeks to understand how the transnational sphere traverses not just space but also time. I analyze how the Palestinian Youth Movement and the Gaza Youth Breaks Out movement understand themselves as carrying the burden of past violences in their promise to continue the Palestinian struggle and lead it toward a just and peaceful solution. Particularly, I am interested in how these movements interpret and conceive of the violences of 1948 and their continuation in present violences from different temporal, and not just spatial, standpoints. I examine the temporalities from which and to which transnational Palestinian movements speak, as well as how they orient themselves, through backward and forward movements, toward past–present–future. The article highlights how temporal differences form tensions that are often overlooked by transnational scholars and activists.     

McTaggart’s Paradox and Crisp’s Presentism

In his review of The Ontology of Time, Thomas Crisp (Notre Dame Philosophical Reviews, 2005a) argues that Oaklander's version of McTaggart's paradox does not make any trouble for his version of presentism. The aim of this paper is to refute that claim by demonstrating that Crisp's version of presentism does indeed succumb to a version of McTaggart's argument. I shall proceed as follows. In Part I I shall explain Crisp's view and then argue in Part II that his analysis of temporal becoming, temporal properties and temporal relations is inadequate. Finally, in Part III, I shall demonstrate that his presentist ontology of time is susceptible to the paradox he so assiduously sought to avoid.     

Aestheticized Institutionalism and Wollheim's Dilemma

In The Aesthetic Function of Art (2004), I was mainly concerned to show how my “new aestheticism” can meet standard objections to aestheticism, but I have come to realize that, since it is as much a new institutionalism as it is a new aestheticism, its institutionalist aspect requires defense as much as its aestheticist aspect does. In this article, I show how a judicious aestheticizing of George Dickie's second version of the institutional theory of art, incorporating fundamental features of my own view, can meet what seems to me to be the most serious objection to institutionalism in general, the dilemma famously proposed by Richard Wollheim.     

Temporal Metaphysics in Z-Land

John Perry has argued that language, thought and experience often contain unarticulated constituents. I argue that this idea holds the key to explaining away the intuitive appeal of the A-theory of time and the endurance theory of persistence. The A-theory has seemed intuitively appealing because the nature of temporal experience makes it natural for us to use one-place predicates like past to deal with what are really two-place relations, one of whose constituents is unarticulated. The endurance view can be treated in a similar way; the temporal boundaries of temporal parts of objects are unarticulated in experience and this makes it seem that the very same entity exists at different times.     

Place and World: On Jeff Malpas’ Second Edition of Place and Experience

ABSTRACT

Jeff Malpas’ book Experience and Place has become a significant landmark in philosophy. I take the publication of the revised and extended second edition of the book in 2018 as an opportunity to reflect on some key issues in Malpas’ thought. After briefly outlining Malpas’ commitment to topophilia and topoanalysis, I address, in the first part of my essay, the relation of place to subjectivity and normativity, pointing out certain shortcomings or ambiguities in Malpas’ account. I also critically discuss the omission of an account of migration, or, rather, immigration, which seems called for, especially if we realize that the inhabited place always comes with its limit or border, which implies that there is also a view from outside, and that we have moral obligations to the stranger and/or immigrant coming into our place from outside. In the second part of my essay, I engage Malpas’ argument according to which Heidegger ‘derived’ space from time. By an analysis of relevant texts in Heidegger, I show that this argument does not hold.     

Alan: An Action Language For Modelling Non-Markovian Domains

In this paper we present the syntax and semantics of a temporal action language named Alan, which was designed to model interactive multimedia presentations where the Markov property does not always hold. In general, Alan allows the specification of systems where the future state of the world depends not only on the current state, but also on the past states of the world. To the best of our knowledge, Alan is the first action language which incorporates causality with temporal formulas. In the process of defining the effect of actions we define the closure with respect to a path rather than to a state, and show that the non-Markovian model is an extension of the traditional Markovian model. Finally, we establish relationship between theories of Alan and logic programs.
