Surface presentism is the combination of a general relativistic physics with a presentist metaphysics. In this paper, we provide an argument against this combination based on black holes. The problem focuses on the notion of an event horizon. We argue that the present locations of event horizons are ontologically dependent on future black hole regions, and that this dependence is incompatible with presentism. We consider five responses to the problem available to the surface presentist, and argue that none succeed. Surface (...) presentism thus faces the prospect of refutation based on evidence that confirms the existence of black holes. (shrink)

In this paper, we defend Lucretian Presentism. Although the view faces many objections and has proven unpopular with presentists, we rehabilitate Lucretianism and argue that none of the objections stick.

David Lewis sells modal realism as a package that includes an eternalist view of time. There is, of course, nothing that ties together the thesis that modality should be analyzed in terms of "concrete" possibilia with the view that non-present things exist. In this paper I develop a theory I call \emph{modal realist presentism} that is a combination of modal realism and presentism, and argue that is has compelling answers to some of the main objections to presentism, including the arguments (...) from (i) singular propositions, (ii) cross-temporal relations, and (iii) truthmaking. Toward the end, I compare modal realist presentism favorably to some similar theories, including Bigelow's modal theory of time, Williamson's theory of the ex-concrete, and Dainton's theory of many-worlds presentism.

Temporal ersatzism is the view that past entities exist, but are not concrete. The view is analogous to modal ersatzism, according to which merely possible worlds exist, but are not concrete. The goal of this paper is to give the reader a sense of the scope of available temporal ersatzist views, the ways in which the analogy with modal ersatzism may be helpful in characterizing and defending those views, and the sorts of considerations that are relevant when evaluating particular versions (...) of temporal ersatzism.

Presentists, who believe that only present objects exist, should accept a thisness ontology, since it can do considerable work in defence of presentism. In this paper, I propose a version of presentism that involves thisnesses of past and present entities and I argue this view solves important problems facing standard versions of presentism.

Presentism faces a familiar objection from truthmaker theory. How can propositions about the past be made true if past entities do not exist? In answering this question, there are, broadly, two roads open to the presentist. The easy road to presentism proceeds by capitulating to the demands imposed by truthmaker theory and finding truthmakers for claims about the past. This road typically involves the invocation of controversial metaphysical posits that must then be defended. The hard road to presentism resists the (...) demands of truthmaker theory by denying that all truths must be truth-made. The road is hard as it requires providing a principled restriction on the scope of truthmaker theory. In this paper, I argue that the hard road collapses back into the easy road; there is no hard road to presentism. (shrink)

Presentists, who believe that only present objects exist, face a problem concerning truths about the past. Presentists should (but cannot) locate truth-makers for truths about the past. What can presentists say in response? We identify two rival factions ‘upstanding’ and ‘nefarious’ presentists. Upstanding presentists aim to meet the challenge, positing presently existing truth-makers for truths about the past; nefarious presentists aim to shirk their responsibilities, using the language of truth-maker theory but without paying any ontological price. We argue that presentists (...) should be nefarious presentists. (shrink)

Presentism faces a serious challenge from truthmaker theory. Standard solutions to the truthmaker objection against presentism proceed in one of two ways. Easy road presentists invoke new entities to satisfy the requirements of truthmaker theory. Hard road presentists, by contrast, flatly refuse to give in to truthmaker demands. Recently, a third way has been proposed. This response seeks to address the truthmaking problem by tensing our truthmaker principles. These views, though intuitive, are under-developed. In this paper, I get serious about (...) a fundamentally tensed approach to truthmaking by sketching out the underlying ontological picture needed to make sense of tensed truthmaker theory. (shrink)

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. (shrink)

The aim of the present paper is to show that presentism cannot answer the truthmaker objection in a satisfactory manner. For such, two main categories of presentist solutions were studied: the first kind states that truthmakers can’t provide any objection to presentism, while the second type tries to ground past truths by postulating new ontological categories, which were rejected, mainly because of their use of ad hoc ontologies. Also, I showed how the presentist should adopt antirealism about the past in (...) case she wants to maintain a simple ontology. Being that said, I conclude that presentism cannot offer satisfactory truthmakers to past truths. (shrink)

In this paper I consider the aboutness objection against standard truth-preserving presentism (STP). According to STP: (1) past-directed propositions (propositions that seem to be about the past) like , are sometimes true (2) truth supervenes on being and (3) the truth of past-directed propositions does not supervene on how things were, in the past. According to the aboutness objection (3) is implausible, given (1) and (2): for any proposition, P, P ought to be true in virtue of what P is (...) about, and so it is upon the past that the truth of past-directed propositions ought to supervene. Although an objection along these lines has been offered previously, I press the objection in two ways. First, by providing needed support for the view that propositions ought to be true in virtue of what they are about and, second, by arguing that the two responses available to the proponent of STP fail to be compelling.

One of the major difficulties facing presentism is the problem of causation. In this paper, I propose a new solution to that problem, one that is compatible with intrinsic, fundamental causal relations. Accommodating relations of this kind is important because (i) according to David Lewis (2004), such relations are needed to account for causation in our world and worlds relevantly similar to our own, (ii) there is no other strategy currently available that successfully reconciles presentism with relations of this kind (...) and (iii) resolving the problem of causation by accommodating intrinsic, fundamental causal relations provides the presentist with a far more general solution to the problem of causation than those currently on offer.

This paper introduces a new theory in temporal ontology, ‘wave theory’, and argues for its attractions over and above existing tensed theories of time.

Presentism is held by most to be the intuitive theory of time, due in large part to the view's supposed preservation of time's passage. In this paper, I strike a blow against presentism's intuitive pull by showing how the presentist, contrary to overwhelming popular belief, is unable to establish temporal change upon which the passage of time is based. I begin by arguing that the presentist's two central ontological commitments, the Present Thesis and the Change Thesis, are incompatible. The main (...) problem is that satisfying the Change Thesis to establish passage requires the existence of more than one moment. This conflicts with the Present Thesis that only the present moment exists. The presentist's response is to appeal to surrogates to stand proxy for the past, so as to account for the difference between what does exist and what did exist. I argue that, for this surrogate strategy to be successful, the proposed surrogates must track what actually happened. I demonstrate that there is no guarantee that t.. (shrink)

An advantage of a typical growing block theory (GBT) or moving spotlight theory (MST) is that it can easily account for tenseless or tensed truths involving past entities. The paper indicates what is required for such an advantage is that a particular like a rock doesn’t change its status of being a rock when turning past from being present. But a typical GBT or MST, which implies that a particular’s turning past from being present doesn’t make a physical difference, faces (...) a series of problems. The paper then regards the exclusion of the implication of making no physical difference by a typical GBT or MST as the second requirement for being a tenable GBT or MST. It’s difficult to satisfy both requirements – even Miller’s (2019) MWT fails to do so. The paper shall reveal how a GBT can satisfy both requirements. (shrink)

A platonic theory of possibility states that truths about what’s possible are determined by facts about properties not being instantiated. Recently, Matthew Tugby has argued in favour of this sort of theory, arguing that adopting a platonic theory of possibility allows us to solve a paradox concerning alien properties: properties that might have been instantiated, but aren’t actually. In this paper, I raise a worry for Tugby’s proposal—that it commits us to negative facts playing an important truth-making role—and offer a (...) strategy to avoid the objectionable negativity. (shrink)

The Platonic account of modality says, roughly, that truths about alien possibilities are grounded in uninstantiated universals. Recently, Ingram has raised a problem for this kind of view, which is that it apparently requires negative facts to play a truthmaking role. Ingram offers an alternative Platonic account which makes use of modal instantiation relations. In this paper, I highlight some of the costs of Ingram’s new account and argue that a more appealing version of Platonism—and modal theory in general—is one (...) that is supplemented with an ontology of totality facts.

Typical presentism asserts that whatever exists is present. Moderate presentism more modestly claims that all events are present and thus acknowledges past and future times understood in a substantivalist sense, and past objects understood, following Williamson, as “ex-concrete.” It is argued that moderate presentism retains the most valuable features of typical presentism, while having considerable advantages in dealing with its most prominent difficulties.
