This chapter discusses several possible reasons why works by women philosophers have traveled significantly less than those written by men, although women’s contributions go back to the start of European history of philosophy. Differentiating between geographic, linguistic, historic and philosophical travels, Tove Pettersen claims that gender is particularly significant with regard to historical and philosophical traveling. As the case of women philosophers clearly demonstrate, gender hampers the circulation of certain texts and inhibit transhistorical exchange of knowledge and ideas. (...) ****** Che chapitre examine plusieurs raisons possibles pour expliquer pourquoi les œuvres de femmes philosophes ont “voyage” beaucoup moins que celle des hommes, bien que la contribution des femmes remonte au début de l´histoire européenne de la philosophie. Distinguant entre plusieurs façons de voyager – géographique, linguistique, historique et philosophique –, Tove Pettersen soutient que le “genre” est un facteur particulièrement significative par rapport au voyage historique et philosophique- Comme le démontre clairement le cas des femmes philosophes, leur genre nuit á la circulation de certains textes ainsi qu’à l’échange transnational du savoir et des idées.

Philosophical reflections on journeys and crossings, homes and habitats, have appeared in all major East Asian and Western philosophies. Landscape and travelling first emerged as a key issue in ancient Chinese philosophy, quickly becoming a core concern of Daoism and Confucianism. Yet despite the eminence of such reflections, Landscape and Travelling East and West: A Philosophical Journey is the first academic study to explore these philosophical themes in detail. Individual case studies from esteemed experts consider how philosophical thought about places (...) and journeys have inspired and shaped major intellectual and cultural traditions; how such notions concretely manifested themselves in Chinese art, particularly in the genres of landscape painting and garden architecture. The studies present a philosophical dialogue between Confucianism and Daoism on issues of social space and belonging and include discussion on travel and landscape in Buddhism as well as Japanese and Tibetan contexts. Approaching the topic from an inter-cultural perspectives, particularly East Asian philosophies, and using these to enrich contemporary reflections on space, the environment, and traversing, this unique collection adds an important voice to present philosophical, political, and cultural discourses.

In this chapter, I present some philosophical reflections on the theme of the imagination. The main inspiration for these reflections comes from two writers, both of whom are mentioned in Alain de Botton’s (2003) The Art of Travel: Joris-Karl Huysmans and Xavier de Maistre. De Botton uses both of these writers in his book as ‘guides’, people whose work prompts his own ruminations, Huysmans in the first chapter and de Maistre in the last. Speculatively, I infer from this structure (...) that de Botton has identified a similarity in the two writers’ attitudes to the relationship between travel and the imagination such that he regards it as appropriate to begin with one and to end with the other. There is a sense, I speculate, in which the wheel is meant to come full circle in de Botton’s book. Both Huysmans and de Maistre seem to be of the opinion that the nature of the imagination is such that it makes travel possible anywhere, notably and counter intuitively, in the place where travel typically both begins and ends: in the traveller’s own home. As I shall shortly suggest in more detail, Huysmans and de Maistre seem to agree that travelling in the imagination alone is preferable in certain ways to the real thing. Whether or not I am right in my speculative attribution of this observation to de Botton, I want, in this chapter, to extend it. I want to suggest that, although Huysmans and de Maistre do indeed draw similar conclusions about travel, they do so for very different reasons. I argue that Huysmans and de Maistre have radically opposing views of the nature of the relationship between the world of the imagination and the real world and therefore of the relationship between travel and the imagination. Using this contrast as a point of departure, I examine the role of the imagination in de Maistre’s travel literature and draw out its philosophical significance, articulating some philosophical insights de Maistre provides about the nature of the imagination per se and its role in human life.

The first ever history of the places where history and philosophy meet, from the Age of Discovery in the sixteenth century to contemplation of how space travel will affect our understanding of who we are in the twenty-first. This book will reshape your understanding of travel.

What is it to remember an episode from one’s past? How does episodic memory give us knowledge of the personal past? What explains the emergence of the apparently uniquely human ability to relive the past? Drawing on current research on mental time travel, this book proposes an integrated set of answers to these questions, arguing that remembering is a matter of simulating past episodes, that we can identify metacognitive mechanisms enabling episodic simulation to meet standards of reliability sufficient for (...) knowledge, and that the subjective experience of reliving the past is a precondition for the reliability of simulational remembering. The resulting account of memory, memory knowledge, and their evolution will be of interest both to philosophers interested in empirically-informed approaches to memory and to psychologists interested in the philosophical implications of empirical memory research.

his article develops a framework for addressing racial ontologies in transnational perspective. In contrast to simple contextualist accounts, it is argued that a globally engaged metaphysics of race needs to address transnational continuities of racial ontologies. In contrast to unificationist accounts that aim for one globally unified ontology, it is argued that questions about the nature and reality of race do not always have the same answers across national contexts. In order address racial ontologies in global perspective, the article develops (...) a framework that accounts for both continuities and discontinuities by looking beyond the referents of narrowly defined core concepts. By shifting the focus from narrow concepts to richer conceptions of race, racial ontologies become comparable through globally related but nonetheless distinct mappings between conceptions and property relations. The article concludes by showing how this framework can generate novel insights in case studies from Asia, Europe, and Latin America. (shrink)

There is a growing body of scholarship that is addressing the ethics, in particular, the bioethics of space travel and colonisation. Naturally, a variety of perspectives concerning the ethical issues and moral permissibility of different technological strategies for confronting the rigours of space travel and colonisation have emerged in the debate. Approaches ranging from genetically enhancing human astronauts to modifying the environments of planets to make them hospitable have been proposed as methods. This paper takes a look at (...) a critique of human bioenhancement proposed by Mirko Garasic who argues that the bioenhancement of human astronauts is not only functional but necessary and thus morally permissible. However, he further claims that the bioethical arguments proposed for the context of space do not apply to the context of Earth. This paper forwards three arguments for how Garasic’s views are philosophically dubious: (1) when he examines our responsibility towards future generations he refers to a moral principle (which we will call the principle of mere survival) which, besides being vague, is not morally acceptable; (2) the idea that human bioenhancement is not natural is not only debatable but morally irrelevant; and (3) it is not true that the situations that may arise in space travel cannot occur on Earth. We conclude that not only is the (bio)enhancement of humans on Earth permissible but perhaps even necessary in certain circumstances. (shrink)

I start off by relating the standard philosophical account of what time travel is to models of time travel that have recently been discussed by physicists. I then discuss some puzzles associated with time travel. I conclude that philosophers’ arguments against time travel are relevant when assessing the likelihood of the occurrence time travel in our world, and are relevant to the assessment whether time travel is physically possible.

The goal of this paper is to defend the general tenet that time travelers cannot change the past within B-theoretical models of time, independently of how many temporal dimensions there are. Baron Pacific Philosophical Quarterly, 98, 129–147 offered a strong argument intended to reach this general conclusion. However, his argument does not cover a peculiar case, i.e. a B-theoretical one-dimensional model of time that allows for the presence of internal times. Loss Pacific Philosophical Quarterly, 96, 1–11 used the latter model (...) to argue that time travelers can change the past within such model. We show a way to debunk Loss’s argument, so that the general tenet about the impossibility of changing the past within B-theoretical models is maintained. (shrink)

Thinking about time travel is an entertaining way to explore how to understand time and its location in the broad conceptual landscape that includes causation, fate, action, possibility, experience, and reality. It is uncontroversial that time travel towards the future exists, and time travel to the past is generally recognized as permitted by Einstein’s general theory of relativity, though no one knows yet whether nature truly allows it. Coherent time travel stories have added flair to traditional (...) debates over the metaphysical status of the past, the reality of temporal passage, and the existence of free will. Moreover, plausible models of time travel and time machines can be used to investigate the subtle relation between space-time structure and causality. -/- It surveys some philosophical issues concerning time travel and should serves as a quick introduction. It includes a new and improved way to define a time machine. (shrink)

The subject of time travel has been receiving increasing attention in the recent philosophical literature. Most of the articles that deal with it have been concerned to defend the logical consistency of time travel against those who claim that it entails one or more contradictions. Two sorts of defences have been offered. The first sort of defence involves showing that time travel does not entail those consequences which other philosophers allege it does entail. The second sort (...) of defence involves an admission that time travel does indeed involve that which its opponents allege it does involve, e.g., being in more than one place at a time, but arguing that such consequences in no way vitiate the logical consistency of this notion.My first aim in this paper is to provide a defence of time travel of the second sort. More specifically, I want to cut the ground from under an argument which might run thus:Time travel entails that certain effects can precede their causes.It is logically impossible for an effect to precede its cause.

Space and time are the most fundamental features of our experience of the world, and yet they are also the most perplexing. Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries, or is it infinite? Is change really possible? Could space and time exist in the absence of any objects or events? What, in the end, are space and time? (...) Do they really exist, or are they simply the constructions of our minds? Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time, but he also gives us the basis to think about these problems independently, avoiding large amounts of jargon and technicality. His book is an invitation to think philosophically rather than a sustained argument for particular conclusions, but Le Poidevin does advance and defend a number of controversial views. He argues, for example, that time does not actually flow, that it is possible for space and time to be both finite and yet be without boundaries, and that causation is the key to an understanding of one of the deepest mysteries of time: its direction. Drawing on a variety of vivid examples from science, history, and literature, Travels in Four Dimensions brings to life some of the most profound questions imaginable. (shrink)

Counterpath is a collaborative work by Catherine Malabou and Jacques Derrida that answers to the gamble inherent in the idea of “travelling with” the philosopher of deconstruction. Malabou's readerly text of quotations and commentary demonstrates how Derrida's work, while appearing to be anything but a travelogue, is nevertheless replete with references to geographical and topographical locations, and functions as a kind of counter-Odyssey through meaning, theorizing, and thematizing notions of arrival, drifting, derivation, and catastrophe. In fact, by going straight to (...) the heart of the Derridean idea of “spacing,” she finally makes it seem as though Derrida has never written about anything but travel.

Writing in a familiar and unguarded manner, as if he were “on vacation” from his own writing, Derrida still remains totally faithful to that work and invites the reader to reflect on much of what haunts his texts as well as his daily life, questions of distance and death, the relation to the other, and exile.

There is an extensive literature on time travel in both philosophy and physics. Part of the great interest of the topic stems from the fact that reasons have been given both for thinking that time travel is physically possible—and for thinking that it is logically impossible! This entry deals primarily with philosophical issues; issues related to the physics of time travel are covered in the separate entries on time travel and modern physics and time machines. We (...) begin with the definitional question: what is time travel? We then turn to the major objection to the possibility of backwards time travel: the Grandfather paradox. Next, issues concerning causation are discussed—and then, issues in the metaphysics of time and change. We end with a discussion of the question why, if backwards time travel will ever occur, we have not been visited by time travellers from the future. (shrink)

I argue that David Lewis’s philosophically dominant conception of time travel cannot straightforwardly handle what we might call cases of relativistic time travel—that is, the sort of time travel which could only plausibly occur in a relativistic setting. I evaluate whether or not the Lewisian account can be successfully adapted such that it would able to analyse potential cases of relativistic time travel satisfactorily while still being employable in the analysis of those cases that make no (...) mention of physics or the structure of spacetime. This is primarily an analytical and explanatory exercise, rather than a polemical one. (shrink)

We have argued elsewhere that moral responsibility over time depends in part upon the having of psychological connections which facilitate forms of self-control. In this chapter we explore the importance of mental time travel - our ordinary ability to mentally travel to temporal locations outside the present, involving both memory of our personal past and the ability to imagine ourselves in the future - to our agential capacities for planning and control. We suggest that in many individuals with (...) dissociative disorders, forms of amnesia, or other frontal lobe damage, our capacity for mental time travel is impaired, resulting in commensurate losses to agency autonomy, and a forensic condition essential for holding persons responsible: in legal terms, the capacity for mens rea.

The present paper offers a philosophical discussion of phenomena which in the empirical literature have recently been subsumed under the concept of ‘mental time travel’. More precisely, the paper considers differences and similarities between two cases of ‘mental time travel’, recollective memories (‘R-memories’) of past events on the one hand, and sensory imaginations (‘S-imaginations’) of future events on the other. It develops and defends the claim that, because a subject who R-remembers a past event is experientially aware of (...) a past particular event, while a subject who S-imagines a future event could not possibly be experientially aware of a future particular event, R-memories of past events and S-imaginations of future events are ultimately mental occurrences of two different kinds.

A testimony is somebody else’s reported experience of what has happened. It is an indispensable source of knowledge. It only gives us historical cognition, however, which stands in a complex relation to rational or philosophical cognition: while the latter presupposes historical cognition as its matter, one needs the architectonic “eye of a philosopher” to select, interpret, and organize historical cognition. Kant develops this rationalist theory of testimony. He also practices it in his own work, especially while theorizing about race as (...) a subject of natural philosophy. In three dedicated essays on this subject, he treats race from the standpoint of a philosophical investigator of nature (Naturforscher), who (as Kant puts it in the first Critique) learns from nature “like an appointed judge who compels witnesses to answer the questions he puts to them.” This view underwrites Kant’s use of travel reports (a type of testimony) in developing and defending his theory of race.

In no possible world does a time traveler succeed in killing herearlier self before she ever enters a time machine. So if many,many time travelers went back in time trying to kill theirunprotected former selves, the time travelers would fail inmany strange, coincidental ways, slipping on bananapeels, killing the wrong victim, and so on. Such cases producedoubts about time travel. How could ``coincidences'' beguaranteed to happen? And wouldn't the certainty of coincidentalfailure imply that time travelers are not free to (...) killtheir earlier selves? But if so, what would inhibit theirfreedom? Despite initial appearances, these and other doubtsmay be answered: the possibility of time travel survives yetanother challenge. (shrink)

It has been suggested that there is something worrisome, puzzling, or incomprehensible about the sorts of causal loops sometimes involved in backwards time travel. This paper disentangles two distinct puzzles and evaluates whether they provide us reason to find backwards time travel incomprehensible, inexplicable, or otherwise worrisome. The paper argues that they provide no such reason.

There is no possible world in which someone travels back in time and kills herself as a baby. All possible worlds are internally consistent; the one just described would not be. For this reason, autoinfanticide is metaphysically impossible. This metaphysical impossibility is philosophically intriguing because unlike most impossible events, we can vividly picture how it might look. Time travel itself seems possible, and for those who arrive in the past with proper equipment and training, the actual infanticide should not (...) be difficult. The considerations in this paper have led me to conclude that there are indeterministic worlds in which instances of autoinfanticide have a chance of succeeding, sometimes even a high chance. Some may be tempted to resist this conclusion, uncomfortable with the notion that something metaphysically impossible can have a positive chance. Understandably, they expect something which happens at no world to also have no chance of happening. However, no plausible theory of chance fits these preconceptions. (shrink)

Some philosophers defend the possibility of synchronic multilocation, and have even used it to defend other substantive metaphysical theses. But just how strong is the case for the possibility of synchronic multilocation? The answer to this question depends in part on whether synchronic multilocation is wedded to other controversial metaphysical notions. In this paper, I consider whether the possibility of synchronic multilocation depends on the possibility of time travel, and I conclude that the answer hinges on the nature (...) of time and persistence.

Emily Thomas's seminal book The Meaning of Travel has brought the philosophy of travel back into the public eye in recent years. Thomas has shown that the topic of travel can be approached from numerous different perspectives, ranging from the historical to the conceptual‐analytical, to the political or even social‐philosophical perspectives. This article introduces another perspective, which Thomas only indirectly addresses, namely the argumentation‐theoretical perspective. It is notable that contemporary philosophy of travel lacks the nineteenth‐century approach (...) of using diagrams and maps to examine arguments for and against travel. Since this approach starts with Schopenhauer, we first introduce his argument maps, discuss their advantages and disadvantages, and argue that a modified version is suitable to visualize and analyze arguments for and against traveling as presented in Thomas's work.

This book continues the exploration of themes either neglected or devalued by others working in the field of philosophy and culture. The authors in this volume consider the domain of travel from the broadest and most diverse of philosophical perspectives, covering everyday topics ranging from commuting and vacation travel to immigration and forced relocation. Our time in transit, our being in transit, and our time at rest, whether by choice or edict, has always been at issue, always been (...) at play, for our species. The essays collected here explore the possibilities of the material impact of being able to move or stay put, as well as being forced to go or prevented from leaving. (shrink)

While many aspects of cognition have been shown to be shared between humans and non-human animals, there remains controversy regarding whether the capacity to mentally time travel is a uniquely human one. In this paper, we argue that there are four ways of representing when some event happened: four kinds of temporal representation. Distinguishing these four kinds of temporal representation has five benefits. First, it puts us in a position to determine the particular benefits these distinct temporal representations afford (...) an organism. Second, it provides the conceptual resources to foster a discussion about which of these representations is necessary for an organism to count as having the capacity to mentally time travel. Third, it enables us to distinguish stricter from more liberal views of mental time travel that differ regarding which kind(s) of temporal representation is taken to be necessary for mental time travel. Fourth, it allows us to determine the benefits of taking a stricter or more liberal view of mental time travel. Finally, it ensures that disagreement about whether some species can mentally time travel is not merely the product of unrecognised disagreement about which temporal representation is necessary for mental time travel. We argue for a more liberal view, on the grounds that it allows us to view mental time travel as an evolutionarily continuous phenomenon, and to recognise that differences in the ways that organisms mentally time travel might reflect different temporal representations, or combinations thereof, that they employ. Our ultimate aim, however, is to create the conceptual framework for further discussion regarding what sorts of temporal representations are required for mental time travel. (shrink)

The idea that episodic memory is a form of mental time travel has played an important role in the development of memory research in the last couple decades. Despite its growing importance in psychology, philosophers have only begun to develop an interest in philosophical questions pertaining to the relationship between memory and mental time travel. Thus, this paper proposes a more systematic discussion of the relationship between memory and mental time travel from the point of view (...) of philosophy. I start by discussing some of the motivations to take memory to be a form of mental time travel. I call the resulting view of memory the mental time travel view. I then proceed to consider important philosophical questions pertaining to memory and develop them in the context of the mental time travel view. I conclude by suggesting that the intersection of the philosophy of memory and research on mental time travel not only provides new perspectives to think about traditional philosophical questions, but also new questions that have not been explored before.

Over the last several decades, slow travel has been garnering increasing attention, especially with regards to the climate crisis and the many harms that result from global tourism. The defenders of slow travel claim that traveling slowly benefits not only the environment but also the local communities most affected by tourism, as well as the travellers themselves. This kind of defence, while seeming to be intuitively correct, is missing a sustained argument that explains why this is the case. (...) In this paper, we fill this explanatory gap by relying on philosopher Albert Borgmann’s theory of devices and focal practices to provide a theoretical ground for the claims made about traveling fast and slow.

ABSTRACTEpisodic memory is the ability to revisit events in one's personal past, to relive them as if one travelled back in mental time. It has widely been assumed that such an ability imposes a metaphysical requirement on selves. Buddhist philosophers, however, deny the requirement and therefore seek to provide accounts of episodic memory that are metaphysically parsimonious. The idea that the memory perspective is a centred field of experience whose phenomenal constituents are simulacra of an earlier field of experience, (...) yet attended to in a way that presents them as happening again, is, I suggest, a better one than that the memory perspective consists in taking as object-aspect the subject-aspect of the earlier experience, or the idea that it consists in labelling a representation of the earlier experience with an I-tag.

Famously, David Lewis argued that we can avoid the apparent paradoxes of time travel by introducing a notion of personal time, which by and large follows the causal flow of the time traveler's life history. This paper argues that a related approach can be adapted for use by three-dimensionalists in response to Ted Sider's claim that three-dimensionalism is inconsistent with time travel. In contrast to Lewis (and others who follow him on this point), however, this paper argues that (...) the order of events captured by so-called "personal time" should be thought of as causal, rather than temporal. (shrink)

It has sometimes been suggested that backwards time travel always incurs causal loops. I show that this is mistaken, by describing worlds where backwards time travel occurs and yet no causal loops occur. Arguments that backwards time travel can occur without causal loops have been given before in the literature, but I show that those arguments are unconvincing.

The Principle of Alternative Possibilities is the intuitive idea that someone is morally responsible for an action only if she could have done otherwise. Harry Frankfurt has famously presented putative counterexamples to this intuitive principle. In this paper, I formulate a simple version of the Principle of Alternative Possibilities that invokes a course-grained notion of actions. After warming up with a Frankfurt-Style Counterexample to this principle, I introduce a new kind of counterexample based on the possibility of time travel. (...) At the end of the paper, I formulate a more sophisticated version of the Principle of Alternative Possibilities that invokes a certain fine grained notion of actions. I then explain how this new kind of counterexample can be augmented to show that even the more sophisticated principle is false. (shrink)

According to the standard definition of time travel due to David Lewis, an object time travels if and only if the separation in time between departure and arrival does not equal the duration of its journey. After arguing that the standard definition of time travel is inadequate by discussing a world with circular time, I suggest a new definition of time travel that does not fail in situations involving circular time.

Suppose that you travel back in time to talk to your younger self in order to tell her that she (you) should have done some things in her (your) life differently. Of course, you will not be able to make this plan work, we know that from the many versions of 'the grandfather paradox' that populate the philosophical literature about time travel. What will be my centre of interest in this paper is the conversation between you and ... (...) you – i.e. the older you that travelled back in time and the younger you, when you first meet. As we shall see, given this situation, endurantists will have to endorse a strange consequence of their view : you will turn out to be a universal while your properties will turn out to be particulars.

This paper examines various philosophical arguments to do with time travel. It argues that time travel has not been shown to be logically impossible. It then considers whether time travel would give rise to improbable strings of coincidences, or closed causal loops. Finally, it considers whether we could ever be justified in believing someone who claimed to be a time traveller, or whether we would always be more justified in believing that the claimant was either deluded or (...) trying to deceive us. For this last issue the Terry Gilliam film ‘Twelve Monkeys’ is used as an example. (shrink)

Kadri Vihvelin, in "What time travelers cannot do" (Philos Stud 81: 315-330, 1996), argued that "no time traveler can kill the baby who in fact is her younger self, because (V1) "if someone would fail to do something, no matter how hard or how many times she tried, then she cannot do it", and (V2) if a time traveler tried to kill her baby self, she would always fail. Theodore Sider (Philos Stud 110: 115-138, 2002) criticized Vihvelin's argument, and Ira (...) Kiourti (Philos Stud 139: 343-352, 2008) criticized both Vihvelin's argument and Sider's critique. I present a critique of Vihvelin's argument different from both Sider's and Kiourti's critiques: I argue in a novel way that both V1 and V2 are false. Since Vihvelin's argument might be understood as providing a challenge to the possibility of time travel, if my critique succeeds then time travel survives such a challenge unscathed. (shrink)

Talk about time travel is puzzling even if it isn't obviously contradictory. Philosophers however are divided about whether time travel involves empirical paradox or some deeper metaphysical incoherence. It is suggested that time travel requires a Parmenidean four-dimensionalist metaphysical conception of the world in time. The possibility of time travel is addressed (mainly) from within a Parmenidean metaphysical framework, which is accepted by David Lewis in his defence of the coherence of time travel. It (...) is argued that time travel raises formidable difficulties which are not satisfactorily resolved by Lewis's ingenious defence of time travel. Objections to time travel considered include: (1) travel to other times is impossible because there is nowhere (or “nowhen”) to go to; (2) the problem that upon setting out on a journey to the past a time machine will collide with itself; (3) time travel generates a mysterious temporal dualism between experiential time and physical time; (4) travel to the past permits reverse causation, raising the possibility of causal loops and attendant problems arising, for example, from the prospect of empirical contradiction and the possibility of someone being one of their ancestors.

This original and accessible text is more than an introduction to comparative philosophy in the East and West. It is also a guide to 'philosophizing' as a thinking process. In addition to outlining the presuppositions of different traditions, it discusses their methods and techniques for reasoning in what the author calls four dimensions of 'philosophical space': object, subject, the situational and the aspective/perspective dimension.

Core principles of mereology have been questioned by appealing to time travel scenarios. This paper questions the methodology of employing time travel scenarios to argue against mereology. We show some time travel scenarios are structurally equivalent to more standard ones not involving time travel; and that the three main theories about persistence through time can each solve both the time travel scenario as well as the structurally similar classical scenario. Time travel scenarios that are (...) not similar to more standard arguments are instead problematic because they are open to different, incompatible interpretations. We conclude that compared to the classical arguments against mereological principles, time travel scenarios do not add anything new. (shrink)

Since 1949, the year that Kurt Gödel presented his solutions to Einstein’s field equations, there has been much discussion of time travel within the philosophical literature. Whereas theorizing about time travel had theretofore been relegated to the realm of science fiction, the imprimatur of Gödel’s work elevated the legitimacy of such discussion. It finally appeared that travel into the past might be a physical—if not yet technological—possibility. For the past few decades, philosophical inquiry into backward time (...) class='Hi'>travel and the closely related topic of backward causation has centered on the logical possibility and conceptual coherence of these phenomena. In this paper, various conceptual problems associated with time travel concerning the nature of agency and nomological structure will be explored. However, the existence of such conceptual difficulties does not threaten the logical or physical possibility of time travel. Ultimately, the most rational stance to take regarding time travel may ultimately be one of epistemic humility, by which is meant a stance involving the admission that conceptual analysis may not constitute a very fruitful methodology for understanding the physical nature of our world.
