The growing block view of time holds that the past and present are real whilst the future is unreal; as future events become present and real, they are added on to the growing block of reality. Surprisingly, given the recent interest in this view, there is very little literature on its origins. This paper explores those origins, and advances two theses. First, I show that although C. D. Broad’s Scientific Thought provides the first defence of the growing block theory, the (...) theory receives its first articulation in Samuel Alexander’s Space, Time, and Deity. Further, Alexander’s account of deity inclines towards the growing block view. Second, I argue that Broad shifted towards the growing block theory as a result of his newfound conviction that time has a direction. By way of tying these theses together, I argue that Broad’s views on the direction of time – and possibly even his growing block theory – are sourced in Alexander. (shrink)

According to the growing block ontology of time, there (tenselessly and unrestrictedly) exist past and present objects and events, but no future objects or events. The growing block is made attractive not just because of the attractiveness of its ontological basis for past-tensed truths, the past’s fixity, and future’s openness, but by underlying principles about the right way to fill in this sort of ontology. I shall argue that given these underlying views about the connection between truth and ontology, growing (...) blockers incur an ontological commitment to an infinite number of temporal dimensions (“hypertime”). This commitment to hypertime generates a vicious explanatory regress. It also undermines the idea that the reality of the past is sufficient to explain why truths about the past are fixed. Both of these implications are highly unattractive; growing blockers would do well to clarify what other motivations they can offer for their view and how they can avoid these consequences. (shrink)

Here I examine some recent attempts to provide a new way of thinking about the philosophy of time that question the central role of ‘presentness’ within the definition of presentism. The central concern raised by these critics turns on the intelligibility and theoretical usefulness of the term ‘is present’. My overarching aim is to at least challenge such concerns. I begin with arguments due to Deasy. Deasy develops a view that he calls ‘transientism’ and that he takes to be a (...) well-motivated version of presentism. I show that both this way of thinking about presentism and the argument supposedly motivating it all fail. I then move to an argument due to Correia and Rosenkrantz. Correia and Rosenkrantz purport to show that presentism can be salvaged without making recourse to the term ‘is present’. I demonstrate that their arguments fail. I then move on to a view, proposed and defended by Merricks, Tallant, and Zimmerman, and show that it has the wherewithal to meet the challenges raised by Williamson who, as noted above, raises genuine concerns about our capacity to define presentism.

In this paper, we show that it is not a conceptual truth about laws of nature that they are immutable (though we are happy to leave it as an open empirical question whether they do actually change once in a while). In order to do so, we survey three popular accounts of lawhood—(Armstrong-style) necessitarianism, (Bird-style) dispositionalism and (Lewis-style) ‘best system analysis’—and expose the extent, as well as the philosophical cost, of the amendments that should be enforced in order to leave (...) room for the possibility of changing laws.

In the current article and contrary to a widespread assumption, I argue that Humeanism and ontological emergence can peacefully coexist. Such a coexistence can be established by reviving elements of John Stuart Mill’s philosophy of science, in which an idiosyncratic account of diachronic emergence is associated with extensions of the Humean mosaic and the correlative coming into being of new best system laws, which have the peculiarity of being temporally indexed. Incidentally, this reconciliation of Humeanism and emergence allows for conceiving (...) the autonomy of the special sciences in an interesting way, consistently with the reductionist ideal of a unified science.

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 this paper I argue that tensed facts are not necessary to ground the fittingness of the type asymmetry, and thus we have no reason, arising from the fittingness of the asymmetry, to posit such facts. I also argue for a stronger conclusion: even if these facts obtain they are no part of what grounds the fittingness of the type asymmetry. These facts are explanatorily redundant. (shrink)

ABSTRACT The following are purported to be common-sense features of the world: time’s passage, the unreality of the future, the existence of ‘genuine’ change. All of these common-sense features are accommodated by accepting the phenomenon of absolute becoming, a view of temporal passage in which the unreal future comes into existence in the present. Indeed, most philosophers who lay claim to common-sense views of time accept absolute becoming. I argue that absolute becoming has deeply unintuitive consequences. Specifically, proponents of absolute (...) becoming face what I call the coordination problem: in the absence of a connection between the existing present and the unreal future, one must, but cannot, explain how whatever comes into existence preserves the continuing regularity of the world. The standard options to explain the continuing regularity of the world take the form of appealing to enforcers—causation, laws of nature, and dispositions—to guarantee that what comes into existence preserves these regularities. I show that the very nature of a world in which there is no future means that enforcers cannot guarantee this regular nature of the world. Absolute becoming should therefore be rejected: the future does not come into existence; it already exists. (shrink)

There is a feeling of dissatisfaction with the traditional way of defining the A-theories of time. One reason is that these definitions rest on an ontological question—‘Do the future and the past exist?’—to which no non-speculative answer can be provided. Another reason is that these definitions fail to distinguish between various A-theories of time at all times and, therefore, cannot be regarded as essential to them. In the present paper, I make a fresh start in the debate, by introducing two (...) questions whose specific answers allow one to get a comprehensive categorization of the A-theories of time. This alternative way of defining the A-theories of time addresses the two above-mentioned issues and reveals the metaphysical singularity of underrated theories, such as the growing block theory.

At first glance, every metaphysics of laws can be combined with every ontology of time. In contrast, the paper intends to show that Humeanism requires eternalism and that Power metaphysics must presuppose an existentially dynamical view of temporal existence, i.e. growing block or presentism. The presented arguments turn out to be completely independent of whether the laws of nature are deterministic or probabilistic: the world is non-productive and static or productively dynamical, the future be ‘open’ or not.

This paper aims to support the claim that analytic metaphysics should be more cautious regarding the constraints that truthmaking considerations impose on metaphysical theories. To this end, I reply to Briggs and Forbes (2017), whoargue that certain truthmaking commitments are incurred by a Humean metaphysics and by the Growing-Block theory. First, I argue that Humean Supervenience does not need to endorse a standard version of truthmaker maximalism. This undermines Briggs and Forbes’s conclusion that Humean Supervenience and the Growing-Block theory are (...) incompatible. Second, I argue that the Growing-Block theory does not commit us to any weaker version of truthmaker maximalism, which also undermines Briggs and Forbes’s conclusion. Finally, I point out other reasons to think that any version of truthmaker maximalism is disputable, undermining a fortiori Briggs and Forbes’s conclusion and supporting the moral that metaphysical theories—or at least Humean Supervenience, the Growing-Block theory, and presentism—are little constrained by truthmaking commitments.

Some theories in the philosophy of time combine a commitment to the existence of non-present regions of spacetime with the view that there is a perspective-independent present time. We call such theories 4D A-theories. There is a well-known objection to 4D A-theories, as follows: 4D A-theories entail that the vast majority of subjects across time believe falsely that they are present. But if the vast majority of subjects across time believe falsely that they are present, we do not know that (...) we are present. We call this the Epistemic Objection to 4D A-theories. In this paper we do two things: first, we describe and assess a number of different versions of the Epistemic Objection. We argue that there is only one version of the objection—the version due to Russell that we call the Safety Argument—that does not rely on implausible epistemic principles which entail radical scepticism. Second, we raise objections to the main strategies adopted by 4D A-theorists in response to the Safety Argument. We conclude that the Epistemic Objection—in the form of the Safety Argument—remains a threat to 4D A-theories. (shrink)

We show that five important elements of the ‘nomological package’— laws, counterfactuals, chances, dispositions, and counterfactuals—needn’t be a problem for the Growing-Block view. We begin with the framework given in Briggs and Forbes (in The real truth about the unreal future. Oxford studies in metaphysics. Oxford University Press, Oxford, 2012 ), and, taking laws as primitive, we show that the Growing-Block view has the resources to provide an account of possibility, and a natural semantics for non-backtracking causal counterfactuals. We show (...) how objective chances might ground a more fine-grained concept of feasibility, and furnished a places in the structure where causation and dispositions might fit. The Growing-Block view, thus understood, provides the resources to explain the close link between modality and tense, so that it predicts modal change as time passes. This account lets us capture not only what the future might hold for us, and also what might have been. (shrink)

As a main challenge to the growing block theory (GBT), the epistemic objection is intended to show that GBT is untenable because it leads to the ignorance of the objective present. What is worse, extant solutions to this objection, the dead past view (DPV) and strong tense views (STV), are unsatisfactory on the ground that their semantic explanations of tensed statements undermine the purported semantic unity of GBT and thus make GBT collapse into a version of presentism. In contrast to (...) extant solutions, I recommend growing blockists to adopt a new “biting the bullet” solution: They should accept the ignorance of the absolute present for the dual purpose of retaining GBT’s semantic unity and theoretical independence. Moreover, I argue that ignorance is not a big loss for growing blockists: Although they lose the so-called “Moorean common advantage” over B-theorists and include some “deeply mysterious” and epistemically inaccessible fundamental posit in their ontology, growing blockists thereby protect the semantic unity of their theory and most of ordinary knowledge about B-relations between moments of time and their temporal locations. Theory choice, in essence, is a matter of balancing benefits and costs. I believe that versions of GBT which accept the ignorance of the objective present are indeed tenable intermediate positions in the philosophical debate about the nature of time, and they deserve serious considerations of B-theorists.

A version of the growing block theory of time is developed based on the choice of both consciousness and mathematics as fundamental substances, while dismissing the reality/semantics distinction usually assumed by works on time theory. The well-analyzable growing block structure of mathematical ontology revealed by mathematical logic, is used as a model for a possible deeper working of conscious time. Physical reality is explained as emerging from a combination of both substances, with a proposed specific version of the Consciousness Causes (...) Collapse interpretation. This leads to new solutions to old problems, including the epistemic problem and issues with Relativity. (shrink)
