It is highly now intuitive that the future is open and the past is closed now—whereas it is unsettled whether there will be a fourth world war, it is settled that there was a first. Recently, it has become increasingly popular to claim that the intuitive openness of the future implies that contingent statements about the future, such as ‘There will be a sea battle tomorrow,’ are non-bivalent (neither true nor false). In this paper, we argue (...) that the non-bivalence of future contingents is at odds with our pre-theoretic intuitions about the openness of the future. These intuitions are revealed by our pragmatic judgments concerning the correctness and incorrectness of assertions of future contingents. We argue that the pragmatic data together with a plausible account of assertion shows that in many cases we take future contingents to be true (or to be false), though we take the future to be open in relevant respects. It follows that appeals to intuition to support the non-bivalence of future contingents are untenable. Intuition favours bivalence. (shrink)

In this paper we aim to disentangle the thesis that the future is open from theses that often get associated or even conflated with it. In particular, we argue that the open future thesis is compatible with both the unrestricted principle of bivalence and determinism with respect to the laws of nature. We also argue that whether or not the future (and indeed the past) is open has no consequences as to the existence of (...) (past and) future ontology. (shrink)

Open future is incompatible with realism about possible worlds. Since realistically conceived (concrete or abstract) possible worlds are maximal in the sense that they contain/represent the full history of a possible spacetime, past and future included, if such a world is actual now, the future is fully settled now, which rules out openness. The kind of metaphysical indeterminacy required for open future is incompatible with the kind of maximality which is built into the concept (...) of possible worlds. The paper discusses various modal realist responses and argues that they provide ersatz openness only, or they lead to incoherence, or they render the resulting theory inadequate as a theory of modality. The paper also considers various accounts of the open future, including rejection of bivalence, supervaluationism, and the ‘thin red line’ view (TRL), and claims that a version of (TRL) can avoid the incompatibility problem, but only at the cost of deflating the notion of openness.

This essay explores the validity of Gregory Boyd’s open theistic account of the nature of the future. In particular, it is an investigation into whether Boyd’s logical square of opposition for future contingents provides a model of reality for free will theists that can preserve both bivalence and a classical conception of omniscience. In what follows, I argue that it can.

This book launches a sustained defense of a radical interpretation of the doctrine of the open future. Patrick Todd argues that all claims about undetermined aspects of the future are simply false.

Empirical evidence suggests that people naïvely represent time as dynamical (i.e. as containing robust temporal passage). Yet many contemporary B-theorists deny that it seems to us, in perceptual experience, as though time robustly passes. The question then arises as to why we represent time as dynamical if we do not have perceptual experiences which represent time as dynamical. We consider two hypotheses about why this might be: the temporally aperspectival replacement hypothesis and the moving open future hypothesis. We (...) then empirically test the moving open future hypothesis. According to that hypothesis, we represent the past as objectively fixed and the future open. And we represent that this objective openness moves as events that were open become fixed, such that in doing so, we represent a privileged moving present. We found no evidence for the moving open future hypothesis, which suggests that further investigation of the temporally aperspectival replacement hypothesis is called for. Our results also shed further light on our understanding of the respects in which we represent the future to be open, which, in turn, has implications for our theorising about the open future. (shrink)

Consider also what I shall call the asymmetry of openness: the obscure contrast we draw between the ‘open future’ and the ‘fixed past.’ We tend to regard the future as a multitude of alternative possibilities, a ‘garden of forking paths’ in Borges’ phrase, whereas we regard the past as a unique, settled, immutable actuality. These descriptions scarcely wear their meaning on their sleeves, yet do seem to capture some genuine and important difference between past and future. (...) What can it be? (shrink)

A commonly held idea regarding the nature of time is that the future is open and the past is fixed or closed. This article investigates the notion that there is an asymmetry in openness between the past and the future. The following questions are considered: How exactly is this asymmetry in openness to be understood? What is the relation between an open future and various ontological views about the future? Is an open (...) class='Hi'>future a branching future? What is the relation between an open future and the question of whether contingent statements about the future are true or false? Is an open future compatible with a single determinate future? (shrink)

In his work on the open future, Patrick Todd outlines three models of how to deal with future contingents. These models must answer two questions: one metaphysical, about what facts there are in the world; one semantic, about how to deal with sentences involving ‘will.’ Model 1 has a privileged timeline. Model 2 has an actual future timeline but leaves it indeterminate which timeline that is. Model 3 has no future timeline. All three give will-sentences (...) a modal treatement, as a box over available futures. I will argue that Todd’s second model has problems and should be improved. The first is that it denies what Todd labels as the basic metaphysical intuition behind open-futurism. The second is that indeterminacy about the facts that characterize the actual timeline breaks through into indeterminate identity. I propose a fix to model 2 eliminating its actual future and resolving an issue that arises in applying the neutral semantics Todd endorses to indeterminate sentences. This improved model, I suggest, may even compare favorably to Todd’s preferred model 3. (shrink)

The talk deals with Aristotle’s famous sea-battle problem concerning the truth values of sentences about contingent future events: If an utterance of the sentence “There will be a sea battle tomorrow” is true, then it seems that it is determined that there will be a sea battle tomorrow. For otherwise, how could the utterance be true? If, however, an utterance of the sentence “There will be a sea battle tomorrow” is false, then it seems that it is determined that (...) there will be no sea battle tomorrow. For otherwise, how could the utterance be false? Thus, it seems that it is determined whether there will be a sea battle tomorrow or not – and so for any future event whatsoever. This, however, is in conflict with the assumption that there is such a thing as an open future, i.e., that at least for some future events, it is not determined whether they will take place or not. Some have argued, in light of this problem, that sentences about f uture events are neither true nor false. In this talk, however, it shall be argued that the sea-battle problem can be resolved in an intuitively plausible manner without giving up the principle of bivalence. (shrink)

These are my materials (a short precis, and replies to Alan Rhoda and Daniel Rubio) for an invited symposium on my book _The Open Future: Why Future Contingents are All False_ (OUP, 2021) in IJPR. [The commentaries from Rhoda/Rubio are available on their respective PhilPapers profiles.].

In this paper, I argue that the thesis that time travel is logically possible, is inconsistent with the necessary truth of any of the usual ‘open futureobjective present’ models of the universe. It has been relatively uncontroversial until recently to hold that presentism is inconsistent with the possibility of time travel. I argue that recent arguments to the contrary do not show that presentism is consistent with time travel. Moreover, the necessary truth of other open future-objective present (...) models which we might, prima facie, have supposed to be more amenable to the possibility of time travel, turn out also to be inconsistent with this possibility.

How we live our lives depends on how we relate to our past, present and future. The article focusses on the relation to our future. The target of my critique is a “planning conception” that imagines the future as a realm that we can rationally plan and form in light of our ends. In the first section I present an outline of the planning conception, building on Bratman’s planning theory and Rawls’ idea of a life plan. The (...) second section highlights the attractions of the planning conception. I argue that this conception offers a prima facie intriguing view of the temporality of human life. It promises a life in which we can control the passage of time. The third section reveals severe limitations of the planning conception. I question the claim that plans are central to our self-understanding and to a good life. The planning conception tends to distort the temporality of human life with respect to past, present and future. Given this diagnosis, I sketch an alternative in the last section of the paper. I explore the temporal specifics of ways of understanding oneself as a person and argue that both the formation and the very form of these ‘ways of being’ do not follow the logic of planning.

Review of Patrick Todd's book, The Open Future: Why Future Contingents are All False, Oxford University Press, 2021.

Todd (2016) proposes an analysis of future-directed sentences, in particular sentences of the form 'will(φ)', that is based on the classic Russellian analysis of definite descriptions. Todd's analysis is supposed to vindicate the claim that the future is metaphysically open while retaining a simple Ockhamist semantics of future contingents and the principles of classical logic, i.e. bivalence and the law of excluded middle. Consequently, an open futurist can straightforwardly retain classical logic without appeal to supervaluations, (...) determinacy operators, or any further controversial semantical or metaphysical complication. In this paper, we will show that this quasi-Russellian analysis of 'will' both lacks linguistic motivation and faces a variety of significant problems. In particular, we show that the standard arguments for Russell's treatment of definite descriptions fail to apply to statements of the form 'will(φ)'. (shrink)

Helen Fielding considers how the repetition of the same can be phenomenally shifted. Considering the phenomenon of death by suicide in response to cyberbullying, she asks how cyberspace as a system can be opened up and become more responsive to the living affect of young women subjected to abuse. At the heart of this problem is the breakdown of personal time into objective time, whereby the inexhaustible potentiality of the living world is collapsed into the indifferent infinity of the possible (...) that, unconnected to living existence, is ultimately a closed system. (shrink)

I draw upon Helen Steward's concept of agential settling to argue that freedom requires an ability to change the truth‐value of tenseless future contingents over time from false to true and that this ability requires a metaphysically open future.

A basic intuition we have regarding the nature of time is that the future is open whereas the past is fixed. For example, whereas we think that there are things we can do to affect how the future will unfold, we think that there are not things we can do to affect how the past unfolded. However, although this intuition is largely shared, it is not a straightforward matter to determine the nature of the asymmetry it reflects. (...) So, in this paper, I survey various philosophical ways of characterizing the asymmetry between the ‘open future’ and the ‘fixed past’ in order to account for our intuition. In particular, I wonder whether the asymmetry is to be characterized in semantic, epistemic, metaphysical or ontological terms. I conclude that, although many of these characterizations may contribute to a global understanding of the phenomenon, an ontological characterization of the asymmetry is to be preferred, since it is superior to the alternatives in explanatory power, intelligibility, and in how it coheres with interesting senses of openness.

I present a ‘stage-theoretical’ interpretation of the supervaluationist semantics for the growing-block theory of time according to which the ‘nodes’ on the branching tree of historical possibilities are taken to be possible stages of the growth of the growing-block. As I will argue, the resulting interpretation (i) is very intuitive, (ii) can easily ward off an objection to supervaluationist treatments of the growing-block theory presented by Fabrice Correia and Sven Rosenkranz, and (iii) is also not saddled by the problems affecting (...) the supervaluationist version of the growing-block theory defended by R. A. Briggs and Graeme A. Forbes. (shrink)

This chapter is about the physics that underwrites asymmetries in our practical relationship to the past and future. It discusses the physical reasons that our actions make a difference to the future but not to the past. This asymmetry is one of two temporal asymmetries that shape our experience of the world. The other is an epistemic asymmetry in the information we have about the past and future. This chapter starts with a brief description of the asymmetries, (...) relay the progress that has been made in the last three centuries understanding the physics that underwrites them, and then discuss the sense in which the future is open to a decision-making agent.

Is the objective passage of time compatible with relativistic physics? There are two easy routes to an affirmative answer: (1) provide a deflationary analysis of passage compatible with the block universe, or (2) argue that a privileged global present is compatible with relativity. (1) does not take passage seriously. (2) does not take relativity seriously. This paper is concerned with the viability of views that seek to take both passage and relativity seriously. The investigation proceeds by considering how traditional A-theoretic (...) conceptions of passage might be generalized to relativistic space-times without incorporating a privileged global present. I argue that the most promising position marries the idea that open possibilities for the future are settled as time passes with a ‘non-standard’ interpretation of the relevant formal models.

In Nothing to Come, Fabrice Correia and Sven Rosenkranz provide a sophisticated, compelling, and thoroughly defended account of the growing block theory. This note critically evaluates two aspects of this account. First, it evaluates Correia and Rosenkranz’s attempt at providing a grounding principle for future truths and argues that this principle fails to make progress in explaining why future truths are true. Second, it evaluates Correia and Rosenkranz’s construal of the open future arguing that the asymmetry (...) in openness with respect to the past and future is not plausibly understood in terms of determinism and indeterminism, and in the final section, it evaluates their claim that a growing block theorist is able to maintain that the future is open in a stronger sense than the block theorist.

I defend a simple argument for why considerations of epistemic probability should lead us away from Open Future views according to which claims about the future are never true.

The actualism/possibilism debate in ethics is traditionally formulated in terms of whether true counterfactuals of freedom about the future (true subjunctive conditionals concerning what someone would freely do in the future if they were in certain circumstances) even partly determine an agent's present moral obligations. But the very assumption that there are true counterfactuals of freedom about the future conflicts with the idea that freedom requires a metaphysically open future. We develop probabilism as a solution (...) to the actualism/possibilism debate, a solution that accommodates an open future requirement for freedom. We argue that probabilism resolves the conflicting intuitions that arise between actualists and possibilists and maintains certain distinct advantages over actualism and possibilism. (shrink)

This volume is the first attempt to engage with the work of one of the most exciting thinkers or our times. The essays in the first section by Nandy are either autobiographical in nature or provide insights into his unique sensibility. The later section offers some analytical perspectives on Nandy's work by contributors including leading scholars in the academy, as well as outside it.

Patrick Todd's The Open Future defends the view that all future contingent statements, like ‘It will rain tomorrow’, are false.1 Not only is ‘It will rain tomor.

Take strong open-future Humeanism (OFH) to comprise the following three tenets: (i) that truth supervenes on being (ii) that there is a dynamic present moment, and (iii) that there are no future facts; that is, contingent propositions about the future obtain truth values only when their referents are actualised (Tooley 1997). On the face of it this is a deeply problematic metaphysic - if there are no future facts then prima facie the Humean can neither (...) provide laws of nature, nor explain the evolution of physical systems, as the Humean takes truths (including nomological truths) to supervene on the omnitemporal mosaic of local particular matters of fact. Hypertemporal Humeanism (HH), the view I propose in this paper, admits of nomological facts whilst granting the ontological and conceptual commitments of OFH. HH provides a coherent account of laws of nature, and (unlike standard Humean conceptions) accommodates the natural intuition that future facts are yet to be determined. Furthermore, although the view arguably struggles to combat the problem of induction, the Hypertemporal Humean is in no worse a position in this respect than the traditional closed-future Humean metaphysics.

This dissertation considers the bases upon which ethical assessments of parental genetic trait selections for their children can be made. It argues that if parents engage in genetic trait selections, they must act to expand their child's range of open futures, not to constrict their child's range of open futures or to differentially shift their child's range of open futures. It contends that other proposed distinctions, including distinctions between normal and diseased states and between treatment selections and (...) enhancement selections, do not provide a sound basis for making ethical assessments of parental genetic trait selections. It contends that children have a right to an open future that parents hold in trust for their children and that parents must respect in making genetic trait selections.It considers examples of possible parental genetic trait selections regarding children's hearing, height and visual acuity. Finally, it addresses a number of concerns about and objections to this proposed basis for ethical assessment and to parental genetic trait selection generally but concludes that none of these concerns or objections are fatal the approach that if parents use parental genetic trait selection, they must do so in ways that expand their child's range of open futures.

The child’s right to an open future aims at protecting the autonomy of the mature person into which a child will normally develop. The justification of state interventions into parental decisions which unduly restrict the options of the prospective adult has to address the problem that the value of autonomy is highly contested in modern pluralist societies. The article argues that the modern majority culture provides young adults with many more options than traditionalist religious communities. However, the options (...) that can be chosen in faith groups, such as the Amish, do not constitute a subset of the options available in the wider society. Therefore, state policies which pursue the goal of providing every child with the greatest possible set of options cannot be based on a neutralist version of political liberalism. The advocates of a child’s right to an open future must rely on a perfectionist version of liberalism which draws on the ideal of leading an autonomous life. Since liberal perfectionism has problematic implications, the article defends a neutralist position that largely refrains from state interference with the educational authority of fundamentalist religious communities.

In this essay I respond to three of the most forceful objections to the open view of the future. It is argued that a) open view advocates must deny bivalence; b) the open view offers no theodicy advantages over classical theism; and c) the open view can’t assure believers that God can work all things to the better. I argue that the first objection is premised on an inadequate assessment of future tensed propositions, the (...) second is rooted in an inadequate assessment of free will, and the third is grounded in an inadequate assessment of God’s intelligence.

It is common to cite the child’s “right to an open future” in discussions of how parents and the state may and should treat children. However, the right to an open future can only be useful in these discussions if we have some method for deriving the content of the right. In the paper in which he introduces the right to an open future Joel Feinberg seems to provide such a method: he derives the (...) right from the content of adult autonomy rights. In this paper I argue that his argument fails. If it is to give us guidance about the content of the child’s right to an open future, then the right should be interpreted as a right to a maximally open future. But this strong interpretation is unjustified: the arguments that can be found in Feinberg in favor of the right are invalid, and, in any case, this interpretation has implausible implications. A moderate interpretation of the right to an open future, according to which children have a right to acquire some reasonable range of skills and options, is more plausible. However, if a moderate interpretation is correct, there is not only no argument in Feinberg to support it, there is also no method for deriving the content of the right. Without such a method we have to bring in other moral considerations in order to work out the limits on parental discretion and what children are owed. The right to an open future then does no normative work. (shrink)

I have argued that since (i) intentional agency requires intention-acquisition, (ii) intentionacquisition implies a sense of an open future, and (iii) a sense of an open future is incompatible with complete foreknowledge, then (iv) no agent can be omniscient. Alternatively, an omniscient being is omniimpotent.i David Hunt continues to oppose this reasoning, most recently, in Religious Studies 32 (March 1996). It is increasingly clear that the debate turns on larger issues concerning necessity and knowledge, but let (...) me here offer a few comments in defense of my position. (shrink)

:Discussions about the ethical permissibility of pediatric cognitive enhancement frequently revolve around arguments about welfare, and often include an appeal to the child’s right to an open future. Both proponents and opponents of cognitive enhancement claim that their respective positions best serve the interests of the child by promoting an open future. This article argues that this right to an open future argument only captures some of the risks to the welfare of children, therefore (...) requiring a broader ethical approach. Further, it suggests that a thorough moral assessment of the ends pursued is needed before concluding on the moral permissibility of cognitive enhancement in children, which ultimately hinges on the effect on the overall welfare of the child, beyond an open future.

Many of us are tempted by the thought that the future is open, whereas the past is not. The future might unfold one way, or it might unfold another; but the past, having occurred, is now settled. In previous work we presented an account of what openness consists in: roughly, that the openness of the future is a matter of it being metaphysically indeterminate how things will turn out to be. We were previously concerned merely with (...) presenting the view and exploring its consequences; we did not attempt to argue for it over rival accounts. That is what we will aim to do in this paper. (shrink)

I explore the thesis that the future is open, in the sense that future contingents are neither true nor false. The paper is divided into three sections. In the first, I survey how the thesis arises on a variety of contemporary views on the metaphysics of time. In the second, I explore the consequences for rational belief of the ‘Aristotelian’ view that indeterminacy is characterized by truth-value gaps. In the third, I outline one line of defence for (...) the Aristotelian against the puzzles this induces: treating opinion about future contingents as a matter of fictional belief rather than simple belief.

What cognitive goods do children plausibly have a right to in an education? In attempting to answer this question, I begin with a puzzle centred around Feinberg’s observation that a denial of certain cognitive goods can violate a child’s right to an open future. I show that propositionalist, dispositionalist and objectualist characterisations of the kinds of cognitive goods children have a right to run in to problems. A promising alternative is then proposed and defended, one that is inspired (...) in the main by Wittgenstein’s ‘hinge’ epistemology as developed in his posthumous On Certainty. (shrink)

It’s generally thought that we naively or pre-theoretically represent the future to be open. While philosophers have modelled future openness in different ways, it’s unclear which, if any, captures our naïve sense that the future is open. In this paper we focus on just one way the future might count as being open: by being nomically open, and empirically investigate whether our naïve representation of the future as open is partly (...) constituted by representing the future as nomically open. We also investigate the connection between our naïve representation of the future as open, and our representation of time. One of the purported advantages of the growing block theory of time is that it captures our naive sense that the future is open, and the past closed. We investigate whether there is an explanatory connection between people representing the future to be nomically open and representing our world to be a growing block and reflect on the implications of our findings for theorising about future openness and temporal ontology.

Over the past few years, the tree model of time has been widely employed to deal with issues concerning the semantics of tensed discourse. The thought that has motivated its adoption is that the most plausible way to make sense of indeterminism is to conceive of future possibilities as branches that depart from a common trunk, constituted by the past and the present. However, the thought still needs to be further articulated and defended, and several important questions remain (...) class='Hi'>open, such as the question of how actuality can be understood and formally represented in a branching framework. The present volume is intended to be a 360 degree reflection on the tree model. The contributions is gathers concern the model and its alternatives, both from a semantic and from a metaphysical point of view. ​. (shrink)

It is sometimes argued that medical professionals should protect a future child's rights by prohibiting disabled parents from using technology to deliberately have a disabled child because disability is taken as an inevitable, severe threat to a child's otherwise “open” future. I will first argue that the open future that allegedly protects a child's future autonomy is precluded by the very conditions needed to develop that future autonomy. Any child's future will be (...) narrowed as they are socialized in a way that gives them the capacity for autonomous choice. However, oppressive master narratives can diminish a future child's autonomy by distorting their narrative identity and constricting their agency. In fact, the open future argument does just this by advancing one of the most damaging master narratives about disability: that disability inevitably and severely restricts a person's autonomy and closes their future. (shrink)

The aim of this article is to propose a novel supervaluationist theory of ‘actually’ in the open future. First, I will argue that any adequate theory of actuality in a branching setting must comply with three main desiderata. Second, I will prove that none of the actuality operators that have been proposed in the literature is up to the task. Finally, I will propose a novel theory of actuality in the open future combining one of the (...) existing definitions of the actuality operator with a new definition of the historical possibility operator, and argue for its adequacy. The central feature of the theory I will advance is the introduction of an actuality parameter capable of being shifted by the historical possibility operator. I will argue that this account appears to not only be consistent with the idea that the future is genuinely open, but also with the general idea that ‘actually’ is, in a relevant sense, a ‘rigid’ operator.

Although deeply committed to the model of nondirective counseling, most genetic counselors enter the profession with certain assumptions about health and disability—for example, that it is preferable to be a hearing person than a deaf person. Thus, most genetic counselors are deeply troubled when parents with certain disabilities ask for assistance in having a child who shares their disability. This ethical challenge benefits little from viewing it as a conflict between beneficence and autonomy. The challenge is better recast as a (...) conflict between parental autonomy and the child's future autonomy. (shrink)

Review of Patrick Todd's The Open Future (2021, OUP).

The bioethical principle of autonomy is problematic regarding the future of the embryo who lacks the ability to self-advocate but will develop this defining human capacity in time. Recent experiments explore the use of clustered regularly interspaced short palindromic repeats /Cas9 for germline engineering in the embryo, which alters future generations. The embryo’s inability to express an autonomous decision is an obvious bioethical challenge of germline engineering. The philosopher Joel Feinberg acknowledged that autonomy is developing in children. He (...) advocated that to reserve this future autonomy, parents should be guided to make ethical decisions that provide children with open futures. Here, Feinberg’s 1980 open future theory is extended to the human embryo in the context of CRISPR germline engineering. Although the embryo does not possess the autonomous decision-making capacity at the time of germline engineering, the parental decision to permanently change the unique genetic fabric of the embryo and subsequent generations disregards future autonomy. Therefore, germline engineering in many instances is objectionable considering Feinberg’s open future theory. (shrink)

Take open-future Humeanism to comprise the following four tenets: (T1) that truth supervenes on a mosaic of local particular matters of fact; (T2) that there are no necessary connections between distinct existences; (T3) that there is a dynamic present moment; and (T4) that there are no future facts; that is, contingent propositions about the future obtain truth values only when their referents are actualised. Prima facie this is a deeply problematic metaphysic for the Humean, since given (...) that the widely accepted Humean conception takes all truths (inclusive of nomological truths) to supervene on an omnitemporal mosaic of local particular matters of fact, if there are no future facts, then the Humean can neither provide laws of nature, nor justify many everyday inductive inferences. However, I argue that this eternalist metaphysic is in tension with at least one of Hume’s central metaphysical claims concerning causation, e.g. that causal regularities may cease to hold at any time. In this paper I propose and defend one possible open-future Humean metaphysic which admits of “true-to-Hume” causal and nomological facts. Furthermore, although I am happy to concede that induction is problematic for the open-future Humean, I demonstrate that it poses no greater threat to the open-future conception than it does to the popular Lewisian conception of natural law.
