How should one discount utility across time? The conventional wisdom in social science is that one should use an exponential discount function. Such a function is a representation of the axioms that provide a well-defined utility function plus a condition known as stationarity. Yet stationarity doesnt really have much intuitive normative pull on its own. Here I try to cast it in a normative glow by deriving stationarity from two explicitly normative premises, both suggested by the philosophical thesis of (...) class='Hi'>temporal neutralism. Putting the argument in this form helps us better understand exponential discounting and challenges to it. (shrink)

Addressing distributive justice issues in health policy—ranging from the allocation of health system funding to the allocation of scarce COVID-19 interventions like intensive care unit beds and vaccines—involves the application of ethical principles. Should a principle of sustainability be among them? I suggest that while the value of temporal neutrality underlying such a principle is compelling, it is already implicit in the more basic principle of equal treatment. Munthe et al imagine sustainability accompanying four other principles: need, prognosis, (...) equal treatment and cost-effectiveness. Some are spelled out, however, in ways that are ambiguous or incomplete. (shrink)

Tsompanidis, Vasilis_On Two Arguments for Temporally Neutral Propositions.

Suppose that time is infinitely long towards the future, and that each feasible action produces a finite amount of utility at each time. Then, under appropriate conditions, each action produces an infinite amount of utility. Does this mean that utilitarianism lacks the resources to discriminate among such actions? Since each action produces the same infinite amount of utility, it seems that utilitarianism must judge all actions permissible, judge all actions impermissible, or remain completely silent. If the future is infinite, that (...) is, the prospects for utilitarianism look bleak. (shrink)

In this work we answer a long standing request for temporal embeddings of deontic STIT logics by introducing the multi-agent STIT logic TDS . The logic is based upon atemporal utilitarian STIT logic. Yet, the logic presented here will be neutral: instead of committing ourselves to utilitarian theories, we prove the logic TDS sound and complete with respect to relational frames not employing any utilitarian function. We demonstrate how these neutral frames can be transformed into utilitarian temporal frames, (...) while preserving validity. Last, we discuss problems that arise from employing binary utility functions in a temporal setting. (shrink)

Humans’ attitudes towards an event often vary depending on whether the event has already happened or has yet to take place. The dread felt at the thought of a forthcoming examination turns into relief once it is over. People also value past events less than future ones – offering less pay for work already carried out than for the same work to be carried out in the future, as recent research in psychology shows. This volume brings together philosophers and psychologists (...) with a shared interest in such psychological past/future asymmetries. It asks questions such as: What different kinds of psychological past/future asymmetries are there, and how are they related? Under what conditions do humans exhibit them? To what extent do they reflect features of time itself, or particular beliefs people have about time? Are they rational, or at least rationally permissible, or should we aspire to being temporally neutral? What exactly does temporal neutrality consist in? (shrink)

As the introduction and lead article for a special issue of Theory, Culture & Society, ‘Neutral Life/Late Barthes’, this article offers an overview of the ‘new’ Barthes that emerges from the late writings and recent ‘Barthes Studies’. The account centres upon the posthumous publication of Barthes’ three key lecture courses delivered at the Collège de France, at the end of the 1970s, which reflect his preoccupation with the everyday, yet reveal a new degree of sophistication, both formal and conceptual. Presented (...) in their original note form, the lectures present perhaps the clearest affirmative project of Barthes’ entire career. The Neutral in particular is pivotal in understanding an ethics of the late works. While Barthes is perhaps most cited for his rumination on the temporality of the photograph, the lecture courses give rise to an ethics of space and distance, rather than of time and telos. Crucially, for Barthes, the Neutral is not neutrality; it is not divestment, but ‘an ardent, burning activity’. In establishing Barthes’ ethics of a Neutral Life, the articles closes – with reference to Derrida’s mourning of Barthes – with a reminder to read Barthes again, or rather a reminder of our current postponed reading of him.

In this paper, I compare the original version of the enactive view—autopoietic enactivism—with Husserl’s phenomenology, regarding the issue of the relationship between consciousness and nature. I refer to this issue as the “problem of naturalism.” I show how the idea of the co-determination of subject and object of cognition, which is at the heart of autopoietic enactivism, is close to the phenomenological form of correlationism. However, I argue that there is a tension between an epistemological reading of the subject-object correlation (...) that renounces to search for its metaphysical ground, and the enactivist focus on the biological basis of cognition, which seems to imply a view of nature as the metaphysical ground of the conscious mind. A similar problem arises in Husserl’s phenomenology in the contrast between the idea of the fundamental subject-object correlation, the concept of nature as a correlate of transcendental constitution, and the investigation of the corporeal and material grounding of consciousness. I find a way out of this problem by drawing on the distinction between static and genetic phenomenology. I argue that the investigation of the temporality of experience in genetic phenomenology leads us to investigate the metaphysical ground of the subject-object correlation, understood dynamically as co-constitution and co-origination. Then I propose to complement phenomenology and enactivism with a form of neutral monism, which conceives of the co-constitution of subject and object as grounded in a flow of fundamental, pre-phenomenal qualities.

Research targeting emotion’s impact on relational episodic memory has largely focused on spatial aspects, but less is known about emotion’s impact on memory for an event’s temporal associations. The present research investigated this topic. Participants viewed a series of interspersed negative and neutral images with instructions to create stories linking successive images. Later, participants performed a surprise memory test, which measured temporal associations between pairs of consecutive pictures where one picture was negative and one was neutral. Analyses focused (...) on how the order of negative and neutral images during encoding influenced retrieval accuracy. Converging results from a discovery study (N = 72) and pre-registered replication study (N = 150) revealed a “forward-favouring” effect of emotion in temporal memory encoding: Participants encoded associations between negative stimuli and subsequent neutral stimuli more strongly than associations between negative stimuli and preceding neutral stimuli. This finding may reflect a novel trade-off regarding emotion’s effects on memory and is relevant for understanding affective disorders, as key clinical symptoms can be conceptualised as maladaptive memory retrieval of temporal details.

I offer an interpretation and a partial defense of Kit Fine's ‘Argument from Passage’, which is situated within his reconstruction of McTaggart's paradox. Fine argues that existing A-theoretic approaches to passage are no more dynamic, i.e. capture passage no better, than the B-theory. I argue that this comparative claim is correct. Our intuitive picture of passage, which inclines us towards A-theories, suggests more than coherent A-theories can deliver. In Finean terms, the picture requires not only Realism about tensed facts, but (...) also Neutrality, i.e. the tensed facts not being ‘oriented towards’ one privileged time. However unlike Fine, and unlike others who advance McTaggartian arguments, I take McTaggart's paradox to indicate neither the need for a more dynamic theory of passage nor that time does not pass. A more dynamic theory is not to be had: Fine's ‘non-standard realism’ amounts to no more than a conceptual gesture. But instead of concluding that time does not pass, we should conclude that theories of passage cannot deliver the dynamicity of our intuitive picture. For this reason, a B-theoretic account of passage that simply identifies passage with the succession of times is a serious contender. (shrink)

There is a rich tradition within game theory, decision theory, economics, and philosophy correlating practical rationality with impartiality, and spatial and temporal neutrality. I argue that in some cases we should give priority to people over both times and places, and to times over places. I also show how three plausible dominance principles regarding people, places, and times conflict, so that we cannot accept all three. However, I argue that there are some cases where we should give priority (...) to times over people, suggesting that there is impersonal value to the distribution of high quality life over different times.

Proponents of temporal neutrality have challenged the intuitive appeal of future-bias: The intuitive appeal of future-bias is limited to a set of isolated cases that involve only hedonic and self-regarding goods and harms. They suggest that we should treat future-bias as irrational in self-regarding hedonic cases too, or at least not treat the intuitive appeal as evidence for future-bias's permissibility, since hedonic and non-hedonic cases are relevantly similar. This paper defends the rationality of future-bias against this concern. Firstly, (...) hedonic goods and harms mostly concern well-being at a time, while the proposed non-hedonic goods concern lifetime goodness. This is a relevant structural difference between hedonic and non-hedonic goods and harms that warrant different attitude patterns, including the applicability of future-bias. Secondly, the degree of idealisation required to make intuitions favour temporal neutrality obscures the weight of intuitions to a level that makes it unreliable as evidence against the permissibility of future-bias. As temporal neutralists need this degree of idealisation of their cases, the argument fails. In summary, we can keep using intuitive support as evidence for future-bias's rationality, at least when it comes to hedonic goods, but to some extent for its general permissibility. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Anonymous Temporality and Gender:Rereading Merleau-PontyMegan M. BurkeThis Essay Provides a Feminist reading of Merleau-Ponty’s notion of anonymity in order to show that it is a critical resource for a feminist account of gender. For Merleau-Ponty, anonymity is a structure of temporality that is prior to the cogito; it is a time that actualizes the reflective self. It gestures away from ontological commitments rooted in presence and calls attention to (...) how senses inform and actualize one’s reflective experience, which illuminates how it is that certain habits become sedimented or deeply rooted into the structure of one’s lived experience. As such, anonymity provides a useful framework for understanding how and in what ways gender normativity is taken up and resisted in experience. Yet feminist readings of Merleau-Ponty and anonymity are divided. On the one hand, there is a strong criticism of his work in general and anonymity in particular and, on the other hand, there is an effort to recuperate aspects of his project, including anonymity. Four examples can help frame this disparate feminist reception of his work:1. Merleau-Ponty neglects sexual difference. For example, Elizabeth Grosz suggests, “Merleau-Ponty leaves out—indeed, is unable to address—the questions of sexual difference, the question of what kind of human body he is discussing, what kind of perceptual functions, and what kind of sexual desire result from the sexual morphology and particularity of the subject” (Grosz 1994, 10). [End Page 138]2. Anonymity neglects sexual difference. Shannon Sullivan is representative of this point, claiming, “Merleau-Ponty’s notion of the anonymous or impersonal body … leads one to overlook” difference; “Merleau-Ponty fails to realize” difference; “He is wrong” (Sullivan 2001, 71).3. Anonymity illuminates sexual difference. For Silvia Stoller “[W]ith the help of Merleau-Ponty … sexual difference presupposes an anonymous sexuality which underlies gender identifications,” making anonymity important to a phenomenological account of sexual difference (Stoller 2013).4. Merleau-Ponty’s account of embodied subjectivity provides insight into the lived experience of femininity. Feminist analyses of female body comportment, such as those of Iris Marion Young and Sandra Bartky, suggest that gender is a process of sedimentation (Young 1990; Bartky 1990). More specifically, they suggest gender becomes a lived experience through the repetition of particular behaviors and actions such that they become a deeply habituated part of one’s being in the world.While the feminist criticisms of Merleau-Ponty are important insofar as they caution against the acceptance of universal claims about existence, they also overlook anonymity’s relationship to time. Given that Merleau-Ponty’s characterization of anonymity is temporal through and through, this oversight is problematic. Without an account of anonymity as a kind of temporality, we miss the value of anonymity and the further insight that can be drawn from it in relation to gender. In what follows, then, I propose a solution to the disparate reception of his work. I suggest that reading anonymity as a structure of temporality illuminates how gender is taken up in lived experience. And, I suggest that anonymity can provide a strong account of gender normativity when one understands the parallels between sedimentation and anonymity with respect to temporality. By showing the strong connection between sedimentation and anonymous temporality, I suggest that it is ontologically and politically helpful to understand gender as a lived time.In the first section of this paper, I will address the main criticisms of anonymity provided by Shannon Sullivan and Luce Irigaray, while also paying attention to those from Elizabeth Grosz, Judith Butler, and Beata Stawarska. For Sullivan, Grosz, and Butler, Merleau-Ponty’s anonymous body is a neutral body, a body that fails to account for gender differences. Irigaray and Stawarska suggest that anonymity is the mark of patriarchy, making ethical and ontological solipsism fundamental to Merleau-Ponty’s work. In each of these cases, anonymity provides nothing useful for and is, in fact, a detriment to feminist projects.In the second section of this paper, I turn to Stoller’s positive reading of anonymity. For Stoller, anonymity is a political and ethical resource that challenges gender norms because it can allow for transformation in... (shrink)

Data is essential to governing those emerging matters of concern that confront the agrifood every day. But data is no neutral intermediary. It disrupts, exposes, and creates new social, economic, political, and environmental possibilities, whilst simultaneously hiding, excluding, and foreclosing others. Scholars have become attuned to both the constitutive role of data in creating everyday worlds, and the need to develop critical accounts of the materialities, spatialities and multiplicities of data relationships. Whereas this emerging work develops insight to the capacity (...) for data topologies to reterritorialise the spatial performances of everyday life, it has largely reduced the associated temporal dimensions to matters of fact. The effect of these performances has been to naturalize the temporal quality of speed and elide the multiple temporalities required to enact contemporary data worlds. Applying the lenses of infrastructuring, performativity and ferality, this paper explores temporality and data in the everyday worlds produced through the New Zealand kiwifruit industry’s focus on dry matter. The paper argues that temporalities are deeply embedded in the kiwifruit industry’s data relations. We show that while temporal data relations are critical to the industry, we also highlight ways in which those relations introduce new, potentially destabilizing performances into kiwifruit relations.

Emotional fluctuations are ubiquitous in everyday life, but precisely how they sculpt the temporal organisation of memories remains unclear. Here, we designed a novel task – the Emotion Boundary Task – wherein participants viewed sequences of negative and neutral images surrounded by a colour border. We manipulated perceptual context (border colour), emotional-picture valence, as well as the direction of emotional-valence shifts (i.e., shifts from neutral-to-negative and negative-to-neutral events) to create events with a shared perceptual and/or emotional context. We measured (...) memory for temporal order and temporal distances for images processed within and across events. Negative images processed within events were remembered as closer in time compared to neutral ones. In contrast, temporal distances were remembered as longer for images spanning neutral-to-negative shifts – suggesting temporal dilation in memory with the onset of a negative event following a previously-neutral state. The extent of negative-picture induced temporal dilation in memory correlated with dispositional negativity across individuals. Lastly, temporal order memory was enhanced for recently-presented negative (versus neutral) images. These findings suggest that emotional-state dynamics matters when considering emotion-temporal memory interactions: While persistent negative events may compress subjectively remembered time, dynamic shifts from neutral-to-negative events produce temporal dilation in memory, with implications for adaptive emotional functioning.

As with biological systems, spoken languages are strikingly robust against perturbations. This paper shows that languages achieve robustness in a way that is highly similar to many biological systems. For example, speech sounds are encoded via multiple acoustically diverse, temporally distributed and functionally redundant cues, characteristics that bear similarities to what biologists call “degeneracy”. Speech is furthermore adequately characterized by neutrality, with many different tongue configurations leading to similar acoustic outputs, and different acoustic variants understood as the same by (...) recipients. This highlights the presence of a large neutral network of acoustic neighbors for every speech sound. Such neutrality ensures that a steady backdrop of variation can be maintained without impeding communication, assuring that there is “fodder” for subsequent evolution. Thus, studying linguistic robustness is not only important for understanding how linguistic systems maintain their functioning upon the background of noise, but also for understanding the preconditions for language evolution.

Most of us are hedonically future-biased: other things being equal, we prefer pains to be in the past and pleasures to be in the future. Recently, various authors have argued that future bias is irrational, and that we should be temporally neutral instead. I argue that instead of temporal neutrality, the putative counterexamples and the rationales offered for them only motivate a more narrow principle I call Only Action Fixes Utility: it is only when you act on the (...) basis of assigning a utility to an outcome that rationality requires you to give it the same value retrospectively and prospectively, other things being equal. When hedonic experiences are untethered from action, hedonic future bias is rationally permissible. I support this principle by appeal to additional scenarios and more general asymmetries between agential and experiential goods. (shrink)

Our daily lives unfold continuously, yet our memories are organised into distinct events, situated in a specific context of space and time, and chunked when this context changes (at event boundaries). Previous research showed that this process, termed event segmentation, enhances object-context binding but impairs temporal order memory. Physiologically, peaks in pupil dilation index event segmentation, similar to emotion-induced bursts of autonomic arousal. Emotional arousal also modulates object-context binding and temporal order memory. Yet, these two critical factors have (...) not been systematically studied together. To address this gap, we ran a behavioural experiment using a paradigm validated to study event segmentation and extended it with emotion manipulation. During encoding, we sequentially presented greyscale objects embedded in coloured frames (colour changes defining events), with a neutral or aversive sound. During retrieval, we tested participants’ memory of temporal order memory and object-colour binding. We found opposite effects of emotion and event segmentation on episodic memory. While event segmentation enhanced object-context binding, emotion impaired it. On the contrary, event segmentation impaired temporal order memory, but emotion enhanced it. These findings increase our understanding of episodic memory organisation in laboratory settings, and potentially in real life with perceptual changes and emotion fluctuations constantly interacting.

Simone de Beauvoir and Frantz Fanon both argue that oppression fundamentally constrains the subject’s relationship to and embodied experience of time, yet their accounts of temporality are rarely brought together. This paper will explore what we might learn about the operation of different types of reductive temporality if we read Beauvoir and Fanon alongside each other, focusing primarily on the early works that arguably lay out the central concerns of their respective temporal frameworks. At first glance, it seems that (...) these two models of temporality have radically different emphases. While Beauvoir suggests that reductive temporalities work to sever the future from the past and present, Fanon locates this destructive operation in the heightening of their entanglement. However, I will contend that there are deep affinities between these accounts: For both Beauvoir and Fanon, freedom is bound up with futurity, with its lack therefore cashed out in terms of stagnation, repetition, and the entrapment within a hollow moment that prevents authentic projection. Both resist teleological perspectives; problematize the endeavor to describe the structures of lived temporality in neutral terms; and show that temporality is crucial to the pursuit of a political phenomenology. These resonances, however, should only serve to recast rather than dissolve the tension between their approaches; ultimately, we need to acknowledge the distinctiveness of their differing concerns and aims.

Most research on metaphors that construe time as motion (motion metaphors of time) has focused on the question of whether it is the times or the person experiencing them (ego) that moves. This paper focuses on the equally important distinction between metaphors that locate times relative to ego (the ego-based metaphors Moving Ego and Moving Time) and a metaphor that locates times relative to other times (sequence is relative position on a path). Rather than a single abstract target domain TIME, (...) these two kinds of temporal metaphor metaphorize different kinds of temporal concept—perspective-specific vs. perspective-neutral temporal concepts. Recognition of this distinction enhances the explanatory potential of conceptual metaphor theory (Lakoff and Johnson 1980). An example involves the interaction of deixis and the temporal reference crosslinguistically of vocabulary with the spatial meanings in-front and behind. More generally, this approach refines our ability to describe the temporal concepts involved in motion metaphors of time. Such temporal concepts are present not only in the target domains, but also in the source domains of motion metaphors of time, where we find space-to-time metonymy, which may play a role in motivating the metaphors. In order to distinguish such metonymy from metaphor, we need to characterize metaphor as a mapping across frames rather than domains. (shrink)

Emotional stimuli are consistently better remembered than neutral stimuli. However, the reported effects of emotional stimuli on source memory are less consistent. In four experiments, we examined spatial and temporal source memory and free recall for emotional words previously studied in an fMRI experiment. In the fMRI experiment, the unpleasant but not the pleasant words were shown to activate the amygdala. In the experiments reported here, spatial and temporal source memory were reduced for the unpleasant words compared to (...) pleasant and neutral words. Reduced spatial memory for unpleasant words was observed across studies that varied the specific stimuli, task conditions, and incidental versus intentional encoding instructions. Free recall was enhanced for the pleasant and unpleasant words compared to neutral words. The results demonstrate reduced source memory for unpleasant words even when item recall is enhanced. Our findings are consistent with prior reports of amygdala-mediated amnestic effects evoked by unpleasant stimuli. (shrink)

Previous studies consistently showed age-related differences in temporal judgment and temporal memory. Importantly, emotional valence plays a crucial role in older adults’ information processing. In this study, we examined the effects of emotions at the intersection between time and memory, analysing age-related differences in a temporal source memory task. Twenty-five younger adults (age range 18–35), 25 old adults (age range 65–74), and 25 old–old adults (age range 75–84) saw a series of emotional pictures in three sessions separated (...) by a one-day rest period. In the fourth session, participants were asked to indicate in which session (1, 2, or 3) they saw each picture. Results showed that old–old adults tended to collocate negative pictures distant in time, while positive stimuli were remembered as more recent than real, compared to neutral pictures. To a lower extent, people over 65 showed the same pattern of results. In contrast, emotional valence did not affect younger adults’ temporal positioning of stimuli. Current findings fit well with the Socio-Emotional Selectivity Theory’s assumptions and extended the literature on the positivity effect to temporal source memory. (shrink)

Emotionally arousing events may disrupt the ability to bind together different features of items to their context; this holds true both for spatial binding and temporal binding. Nonetheless, memory for emotional events may be enhanced in certain situations. A key factor that might explain the memory–emotion relation is represented by individual differences in cognition. The present study investigated temporal binding for neutral and negative events in a group of 50 undergraduate students, focusing on the role of individual differences (...) in working memory. Temporal binding was assessed with sorting accuracy of various pictorial scripted events, 24 h after encoding. Results showed that higher backward digit span predicted higher binding accuracy; importantly, this was qualified by the interaction with valence, such that higher backward digit span predicted better performance for negative, but not neutral, events. It is concluded that working memory facilitates binding of emotional events to their temporal context during encoding, creating a strong representation, and favouring later retrieval of such bound representations.

Some goals have special significance to agents. For instance, an agent could find her life worth living because she is pursuing her current goal, and the agent could also think that her previous life has no value because she did not pursue the current goal. If an agent’s current goal has special importance to the agent, then in terms of prudence the agent’s decision to obtain her current goal could be permissible even in the case where achieving her previous goal (...) brings out larger advantages. A widely endorsed thesis of prudence (i.e. the temporal neutrality thesis) does not successfully explain this phenomenon of goal achievement. Furthermore, the present-aim thesis and the harmony thesis also fail in explaining why an agent has prudential reason to prioritize her current goal. This paper introduces a new thesis of prudence, according to which an agent’s caring is significant in deciding whether the agent’s actions are prudentially permissible. In particular, after introducing this thesis named the care thesis, I argue that the care thesis can explain why an agent has reason to prioritize her current goal if the agent finds her life worth living due to her current goal. It is permissible that an agent obtains her current goal rather than previous goal because achieving her current goal benefits the agent’s cared one (i.e. the self who pursues her current goal).

An argument against the bias towards the near; how a defence of temporal neutrality is not a defence of S; an appeal to inconsistency; why we should reject S and accept CP.

Should you care less about your distant future? What about events in your life that have already happened? How should the passage of time affect your planning and assessment of your life? Most of us think it is irrational to ignore the future but harmless to dismiss the past. But this book argues that rationality requires temporal neutrality.

This paper challenges the conventional wisdom dominating the social sciences and philosophy regarding temporal discounting, the practice of discounting the value of future utility when making decisions. Although there are sharp disagreements about temporal discounting, a kind of standard model has arisen, one that begins with a normative standard about how we should make intertemporal comparisons of utility. This standard demands that in so far as one is rational one discounts utilities at future times with an exponential discount (...) function. Tracing the justification for this standard through economics, philosophy and psychology, I’ll make what I believe is the best case one can for it, showing how a non-arbitrariness assumption and a dominance argument together imply that discounting ought to be exponential. Ultimately, however, I don’t find the case compelling. Non-exponential temporal discounting is often rational. If this is correct, Instead of trying to ‘fix’ non-exponential discounting because it is irrational and associated with negative life outcomes, we might instead focus attention on why the conditions obtain that make such discounting rational.

In Consequentialism Reconsidered, Carlson strives to find a plausible formulation of the structural part of consequentialism. Key notions are analyzed, such as outcomes, alternatives and performability. Carlson argues that consequentialism should be understood as a maximizing rather than a satisficing theory, and as temporally neutral rather than future oriented. He also shows that certain moral theories cannot be reformulated as consequentialist theories. The relevant alternatives for an agent in a situation are taken to comprise all actions that they can perform (...) in the situation. The defense of this idea necessitates certain modifications to the standard consequentialist criteria of obligatoriness, rightness and wrongness. The problem of whether agents should adapt their actions to their own future actions is also addressed. Further, a conditional analysis of performability is suggested, and it is argued that particular actions should in this connection be regarded as `abstract' rather than `concrete'. The final chapter sketches a consequentialist theory for collective agents. (shrink)

We standardly evaluate counterfactuals and abilities in temporally asymmetric terms—by keeping the past fixed and holding the future open. Only future events depend counterfactually on what happens now. Past events do not. Conversely, past events are relevant to what abilities one has now in a way that future events are not. Lewis, Sider and others continue to evaluate counterfactuals and abilities in temporally asymmetric terms, even in cases of backwards time travel. I’ll argue that we need more temporally neutral methods. (...) The past shouldn’t always be held fixed, because backwards time travel requires backwards counterfactual dependence. Future events should sometimes be held fixed, because they’re in the causal history of the past, and agents have evidence of them independently of their decisions now. We need temporally neutral methods to maintain connections between causation, counterfactuals and evidence, and if counterfactuals are used to explain the temporal asymmetry of causation. (shrink)

Most of us display a bias toward the near: we prefer pleasurable experiences to be in our near future and painful experiences to be in our distant future. We also display a bias toward the future: we prefer pleasurable experiences to be in our future and painful experiences to be in our past.

We conclude that those who reject near bias should instead endorse complete temporal neutrality. (shrink)

Do time travellers retain their normal freedom and abilities when they travel back in time? Lewis, Horwich and Sider argue that they do. Time-travelling Tim can kill his young grandfather, his younger self, or whomever else he pleases—and so, it seems can reasonably deliberate about whether to do these things. He might not succeed. But he is still just as free as a non-time traveller. I’ll disagree. The freedom of time travellers is limited by a rational constraint. Tim can’t reasonably (...) deliberate on killing his grandfather, certain that he’ll fail. If Tim follows his evidence, and appropriately self-predicts, he will be certain he won’t kill his grandfather. So if Tim is both evidentially and deliberatively rational, he can’t deliberate on killing his grandfather. This result has consequences. Firstly, it shows how evidential limits in the actual world contribute to our conception of the future as open. Secondly, it undercuts arguments against the possibility of time travel. Thirdly, it affects how we evaluate counterfactuals in time travel worlds, as well as our own. I’ll use the constraint to motivate an evidential and temporally neutral method of evaluating counterfactuals that holds fixed what a relevant deliberating agent has evidence of, independently of her decision. Using this method, an agent’s local abilities may be affected by what happens globally at other times, including the future. (shrink)

Available from UMI in association with The British Library. Requires signed TDF. ;The thesis consists in the development and application of an ideal utilitarian moral theory. ;In chapter one, classical Mental State and modern Desire theories of prudential value are rejected. In chapter two, perfectionism is rejected and an alternative ideal utilitarian Objective List theory is set out. In chapter three, it is argued that prudential rationality requires maximization and temporal neutrality. The aggregation and incommensurability of values is (...) discussed. In chapter four, it is argued that value alone gives rise to grounding reasons for action; the only values are prudential values; we are required to be personally as well as temporally neutral; moral rationality is maximizing. A problem arising when a certain form of incommensurability is combined with the notion of maximizing expected utility is examined. In chapter five, an intrapersonally indirect form of moral theory is defended. ;In the second, practical part of the thesis, the theory developed in the first part is applied to two moral problems: vegetarianism and future generations. In chapter six, the conclusion is that utilitarianism requires us to eat non-intensively-reared meat and to abstain from intensively reared meat. In chapter seven, population problems arising from Derek Parfit's work are considered in the light of the theory. (shrink)

An important platitude about prudential rationality is that I should not refuse to sacrifice a smaller amount of present welfare for the sake of larger future benefits. I ought, in other words, to treat my present and future as of equal prudential significance. The demands of prudence are less clear, however, when it comes to one’s past selves. In this paper, I argue that past benefits are possible in two ways, and that this fact cannot be easily accommodated by traditional (...) approaches to prudential rationality. Against univocal accounts of prudential rationality, I hold that the possibility of past benefits suggests that a bias toward the present and future is defensible when it comes to some welfare goods, but that prudential reasons are temporally neutral between when it comes to the success or failure of one’s long-term projects.

Sometimes we make decisions which affect our lives at times when we will hold values that are different from our values at the time the decision is made. What is the reasonable way to make such a choice? Some think we should accept a requirement of temporal neutrality and take both sets of values into account, others think we should decide on the strength of our present values, yet others think that in evaluating what will happen at that (...) other time we should use the values that we will endorse at that time instead of our present values. These views see the problem as one about finding some attitude towards time itself that is distinctively rational. This article argues that these views are subject to serious objections. It suggests that instead we should think in terms of well-being. If a person approves of, or positively responds to, the way their life is going they will experience more well-being than if there is no positive response. The article explores the implications of a positive response condition on well-being for deciding what it is rational to do in cases involving changing goals. (shrink)

Prudence and authenticity are sometimes seen as rival virtues. Prudence,as traditionally conceived, is temporally neutral. It attaches no intrinsic significance to the temporal location of benefits or harms within the agent’s life; the prudent agent should be equally concerned about all parts of her life. But people’s values and ideals often change over time, sometimes in predictable ways, as when middle age and parenthood often temporize youthful radicalism or spontaneity with concerns for comfort,security, and predictability. In situations involving diachronic, (...) intrapersonal conflicts of value, prudence—in particular,temporal neutrality—appears to require the agent to subordinate her current ideals to her future ones or at least to moderate pursuit of current ideals in light of future ones. But this demand may seem to sacrifice authenticity, if we suppose that authenticity requires acting on the ideals that the agent reflectively and sincerely accepts at the time of action. This tension between prudence and authenticity raises interesting questions about temporal neutrality, the structure of intrapersonal conflicts of value, the nature of ideals, and the demands of authenticity. After examining various aspects of this puzzle, I defend the commitments of prudence in situations involving intrapersonal value conflict and argue that authenticity—understood as being true to oneself— actually supports temporal neutrality. I conclude by suggesting how this defense of prudence lends credibility to the more general demand of temporal neutrality. (shrink)

Cappelen and Hawthorne’s Relativism and Monadic Truth (2009) offers an extended defense of a thesis they call simplicity, which, in brief, holds that propositions are true or false simpliciter. Propositions are cast in their traditional roles as the contents of assertions, and as the semantic values of declarative sentences in contexts. Simplicity stands in sharp contrast to forms of relativism including, for instance, a form that hold that our claims are true or false only relative to a judge. This applies (...) especially to claims of taste, which come out true or false only relative to the judge who finds things tasty (e.g. Glanzberg 2007, Lasersohn 2005). But simplicity also rejects the more widespread temporalist view that propositions are true or false only relative to a time, and it rejects the even more widely held view that propositions are true or false only relative to a world. One reason that has been advanced for temporalism, e.g. by Kaplan (1989), is that our languages seem to contain non-trivial temporal operators. Hence, the argument goes, the semantic values of sentences need to be temporally neutral, i.e. vary for truth or falsehood with time. The same goes for possible worlds and modal operators. Hence, Kaplan and many others think of the semantic values of sentences as sets of world-time pairs. It has been tempting to apply this sort of argument much more widely, to see the semantic values of sentences as varying not just with world and time, but perhaps with location and other parameters as well.

Discusses whether it is irrational to give no weight to past desires – desires that depend on value judgements or ideals; three attitudes to time: caring more about, or being biased towards, what is near, what is in the future and what is present – whether these attitudes are rational; the direction of causation; how it would be better for us if we were temporally neutral; Time's passage; and the asymmetry in our attitudes to our own lives and the lives (...) of others.

Examines the Present‐aim Theory of rationality, or P; The Instrumental and Deliberative Theories, how desires can be intrinsically irrational, or rationally required; the Critical Present‐aim Theory, or CP; the relations between P, S, CP and morality; and Psychological egoism; offers the best objection to S; and how temporal neutrality is not what distinguishes S from P, or CP.

Can metaphysics yield the consolations of philosophy? One possibility, defended by Derek Parfit, is that reflection on the nature of identity and time could diminish both fear of death and grief. In this paper, I assess the prospect of such consolation, focussing especially on attempts to console a grieving third party. A shift to a reductionist view of personal identity might mean that death is less threatening. However, there is some evidence to suggest that such a shift does not necessarily (...) translate into less death anxiety. Moreover, applied to grief at loss of another, such a perspective may be misdirected. A temporally neutral perspective offers a theoretically powerful way of reducing the sense of loss at being separated in time from a loved one. However, it is unclear whether it is psychologically possible to achieve. Even if it were possible, it may not diminish the pain of separation.I identify a serious challenge to philosophical consolation for grief. The greater the consolation that is offered, the greater the risk of losing important attachments and the less it may be psychologically accessible. (shrink)

Standard theories of rational decision making and rational preference embrace the idea that there is something special about the present. Standard decision theory, for example, demands that agents privilege the perspective of the present (i.e., the time of decision) in evaluating what to do. When forming preferences, most philosophers believe that a similar focus on the present is justified, at least in the sense that rationality requires or permits future experiences to be given more weight than past ones. In this (...) dissertation, I examine such theories in light of the expected success of the agents who follow them. In Chapters 2 and 3, I show that this bias toward the present is a liability: it tends to make agents less successful than they might otherwise be. I also show how these problems can be avoided: In the case of rational decision making, we must privilege the beginning rather than the present (what I call “inceptive maximization”). In the case of rational preferences, we must be completely temporally neutral. -/- In chapters 4 and 5 I introduce a larger framework in which to interpret these results. My core thesis is that practical rationality is a form of conditional reliability. Practically rational decisions, preferences, intentions, or other relevant factors reliably produce whatever we take to be of value, conditional on an agent’s beliefs. This focus on value-conduciveness is thus the analog of the focus on truth-conduciveness in reliability theories of epistemic norms. Like reliabilism in epistemology, I show that practical reliabilism is supported by a methodologically naturalistic approach to normativity. In this way and others, I argue that epistemic and practical reliabilism interconnect to create an overarching theory of normativity. (shrink)

A plausible thought is that we should evaluate counterfactuals in the actual world by holding the present ‘fixed’; the state of the counterfactual world at the time of the antecedent, outside the area of the antecedent, is required to match that of the actual world. When used to evaluate counterfactuals in the actual world, this requirement may produce reasonable results. However, the requirement is deeply problematic when used in the context of explaining causal asymmetry. The requirement plays a crucial role (...) in certain statistical mechanical explanations of the temporal asymmetry of causation. I will use a case of backwards time travel to show how the requirement enforces certain features of counterfactual structure a priori. For this reason, the requirement cannot be part of a completely general method of evaluating counterfactuals. More importantly, the way the requirement enforces features of counterfactual structure prevents counterfactual structure being derived from more fundamental physical structure—as explanations of causal asymmetry demand. Therefore, the requirement cannot be used when explaining causal asymmetry. To explain causal asymmetry, we need more temporally neutral methods for evaluating counterfactuals—those that produce the right results in cases involving backwards time travel, as well as in the actual world.

Part II. Section 6. Responsibility for Self: Meyers criticizes Derek Parfit's arguments against the rationality of temporal neutrality -- in other words, the principle of responsibility to self. She urges that autonomy requires providing for one's future.

Francois Recanati has recently argued that each perceptual state has two distinct kinds of content, complete and explicit content. According to Recanati, the former is a function of the latter and the psychological mode of perception. Furthermore, he has argued that explicit content is temporally neutral and that time-consciousness is a feature of psychological mode. In this paper it is argued, pace Recanati, that explicit content is not temporally neutral. Recanati’s position is initially presented. Three desiderata for a theory of (...) time-consciousness are subsequently introduced. It is then argued that a theory locating time-consciousness as a feature of psychological mode will fail to satisfy these desiderata. In the last section the intentionality of memories is discussed. Using the notion of shiftable indexical, it is argued that memories have the same explicit content as perceptions, but that they nevertheless can have different conditions of satisfaction since they are entertained in different modes.

The inference that things do not matter because they will end is a source of despair for reflective people that features in literature, popular culture, and philosophy. Are there sound arguments in support of the inference? I first review three arguments that have been put forward in the existing philosophical literature and consider the objections that can be made against them. While the objections appear persuasive, these arguments do not exhaust the plausible justifications for the inference. Drawing on examples from (...) philosophy and literature, I introduce two previously undiscussed time-bias arguments in support of the inference that seem to be psychologically powerful. I conclude, however, that the time-bias arguments are also unsound. They involve an inconsistent shift between a temporally neutral and a temporally biased perspective on how the passage of time affects what matters. However the inconsistency is resolved, the conclusion does not follow. (shrink)

Typical justifications of prudence are based on the fact that we are temporally extended agents who remain numerically identical over time. After showing that prudential considerations should instead be based on our identity at a particular time, I outline a normative context for prudential reasons, based on a present commitment to temporal neutrality. I then consider how contingency in the content of a present commitment to temporal neutrality provides a flexible context that can help to resolve (...) current debates about whether agents are required to maximize value, maximin value, minimax loss or are required to conform to any of a host of other options on how to adjudicate various types of conflict between present and future values.

Standard accounts of prudential rationality enjoin temporal neutrality. “Rationality,” or so says Rawls, “requires an impartial concern for all parts of our life.” And while I accept this form of temporal neutrality, I argue in this paper that a powerful rationale exists for a competing form of prudential rationality according to which it is permissible to be biased toward near-future rather than far-future parts of one’s life. After arguing that traditional defenses of temporal neutrality (...) do not succeed against this rationale, I offer a new proposal, drawn from the phenomenon of intrapersonal reactive attitudes.
