This paper examines the way in which Locke's deep and longstanding interest in the non-European world contributed to his views on species and their classification. The evidence for Locke's curiosity about the non-European world, especially his fascination with seventeenth-century travel literature, is presented and evaluated. I claim that this personal interest of Locke's almost certainly influenced the metaphysical and epistemological positions he develops in the Essay. I look to Locke's theory of species taxonomy for proof of this. I (...) argue that Locke uses evidence gathered from the non-European world to (1) show that in taxonomizing objects we rely on their sensible qualities rather than their real essences and to (2) undermine Scholastic Aristotelian views about a mind-independent species/genera structure to the world.

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.

Locke had a lifelong love of travel literature. He was also a proponent of the construction of natural histories. Many commentators have noted that there is a close link between these two interests. They suggest that data gleaned from travel literature was used in the construction of natural histories. This paper uses Locke’s reading of François Pyrard’s Voyage to argue that the relationship between the two genres was closer than has been realized. Specifically, it is argued (...) that Pyrard’s discussion of the coconut displays characteristic features of a natural history. It pays careful attention to first-hand experience. It emphasizes empirical observation and eschews theory and speculation. It focuses on the practical utility of the coconut. And it records a number of specific measurements. These features allowed Locke to read this portion of a piece of travel literature as a piece of natural history. This allows us to recognize that the genres of natural history and travel literature were not distinct for early modern thinkers. They overlapped in significant ways. (shrink)

In this article, I discuss a relatively recent development of Russian interest in Kyiv as a place with symbolic and historical significance for Russian history, which makes it a desirable target in an ongoing war. I trace the changing attitude of Russian travelers towards Kyiv’s history from the mid-eighteenth to the early nineteenth century. Earlier generations of visitors came to Kyiv primarily to visit holy places, with no knowledge of the city’s historical significance, and because it was a more affordable (...) alternative to travel abroad. However, at the end of the eighteenth century, after Catherine II’s royal visit, the publication of guidebooks, and the ascend of history as a discipline, and interest among Russian educated elites, Kyiv’s past became an obsession for many Russian travelers. Their travel accounts were motivated by a search for the past glory of Kyiv. For Russian travelers and authorities, history became one of the key means of appropriation of Kyiv, with a new generation of travelers searching for material evidence connecting Kyivan Rus to the Russian past. However, they were unable to find much material evidence and often used their imagination to present Kyiv as a site of Kyivan Rus history, ignoring the city’s non[1]Russian heritage. (shrink)

Christoph Meiners (1747—1810) was one of 18th-century Europe's most important readers of global travel literature, and he has been credited as a founder of the disciplines of ethnology and anthropology. This article examines a part of his final work, Untersuchungen über die Verschiedenheiten der Menschennaturen [Inquiries on the differences of human natures], published posthumously in the 1810s. Here Meiners developed an elaborate argument, based on empirical evidence, that the different races of men emerged indigenously at different times and (...) in different places in natural history. Specifically this article shows how a sedentary scholar who never left Europe constructed a narrative of human origins and migrations on the basis of (1) French theory from the 1750s (Charles de Brosses and Simon Pelloutier) and (2) data gathered by explorers as reported in travel literature (J. R. Forster, Pérouse, Cook, Marsden). (shrink)

This book explores the way in which, working within the investigative tradition associated with the Royal Society, the philosopher John Locke (1632-1704) used ...

The resercher Ann Talbot presents in this book one of the more complex and in-depth studies ever written about the influence of travel literature on the work of the British philospher John Locke (1632-1704). At the end of the 18th century the study of travel literature was an alternative to academic studies. The philosopher John Locke recommended with enthousiasm these books as a way to comprehend human understanding. Several members of the Royal Society like John Harris (...) (1966-1719) affirmed that the learning that could be obtained through these books was different from the one that provided the educative system of that time. Travel literature could make see the source of the ignorance of the ancients; it stressed the curiosities and extraordinary facts and led to a revision of beliefs and scientific theories of the ancient world. Besides the account of a broad diversity of sujects contributed to the creation of matters of fact, and this was important in order to put rational limits to the descriptions of the world that were commonly accepted.

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)

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for (...) the ideality of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

The Counterhuman Imaginary proposes that alongside the historical, social, and institutional structures of human reality that seem to be the sole subject of the literary text, an other-than-human world is everywhere in evidence. Laura Brown finds that within eighteenth-century British literature, the human cultural imaginary can be seen, equally, as a counterhuman imaginary—an alternative realm whose scope and terms exceed human understanding or order. Through close readings of works by Daniel Defoe, Jonathan Swift, and Alexander Pope, along with lapdog (...) lyrics, circulation narratives that give agency to inanimate objects like coins and carriages, and poetry about the Lisbon earthquake of 1755, Brown traces the ways presence and power of the nonhuman—weather, natural disasters, animals, even the concept of love—not only influence human creativity, subjectivity, and history but are inseparable from them. Traversing literary theory, animal studies, new materialism, ecocriticism, and affect theory, The Counterhuman Imaginary offers an original repudiation of the centrality of the human to advance an integrative new methodology for reading chaos, fluidity, force, and impossibility in literary culture.

Time travel has been a staple of science fiction. With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that time travel is inherently paradoxical. The most famous paradox is the grandfather paradox: you travel back in time and kill your grandfather, thereby preventing your own existence. To avoid inconsistency some circumstance will have to occur which makes you fail in this attempt to (...) kill your grandfather. Doesn't this require some implausible constraint on otherwise unrelated circumstances? We examine such worries in the context of modern physics. (shrink)

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)

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 first section of this article focuses on the treatment of “time travel” in science-fiction literature and film as presented in the secondary literature in that field. The first anthology I will consider has a metaphysical focus, including (a) relating the time travel of science fiction to the banal time travel of all living beings, as we move inexorably toward the future; and (b) arguing for the filmstrip as the ultimate metaphor for time. The second (...) anthology I will consider has a more political focus, arguing that the “special effects” form of science-fiction films, rather than the visual or narrative content of science-fiction-films, is truly imaginative and futural. The second section of this article ties together a variety of concepts and insights between time-travel cinema and Deleuze’s Cinema 1, suggesting (among other things) that (c) time-traveling characters in cinema function as a redoubled phenomenon of the “mobile sections” of Bergsonian duration (in reference to Henri Bergson), and (d) time-travel cinema vividly illustrates the imagistic nature of the entire world.

Written by leading scholars in the field, this collection analyses the notion of travel writing as a genre, while tracing significant examples of Mediterranean travel writing that return us to Ancient Greece, to Medieval pilgrimages, to Venetians diplomatic missions, to an Egyptian's account of Paris in the nineteenth century, to French artistic journeys in North Africa and to contemporary narratives of privileged resettlement, death and dislocation.

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.

Travel route preferences can strongly interact with the events that happened in networked traveling, and this coevolving phenomena are essential in providing theoretical foundations for travel route recommendation and predicting collective behaviour in social systems. While most literature puts the focus on route recommendation of individual scenic spots instead of city travel, we propose a novel approach named City Travel Route Recommendation based on Sequential Events Similarity by applying the coevolving spreading dynamics of the city (...) tour networks and mine the travel spatiotemporal patterns in the networks. First, we present the Event Sequence Similarity Measurement Method based on modelling tourists’ travel sequences. The method can help measure similarities in various city travel routes, which combine different scenic types, time slots, and relative locations. Second, by applying the user preference learning method based on scenic type, we learn from the user’s city travel historical data and compute the personalized travel preference. Finally, we verify our algorithm by collecting data of 54 city travellers of their historical spatiotemporal routes in the ten most popular cities from Mafeng.com. CTRR-SES shows better performance in predicting the user’s new city travel sequence fitting the user’s individual preference. (shrink)

The aim of this research is to propose a framework to remedy potential dignity violations to families with children with disabilities seeking tourism experiences. We build on a systematic literature review on the topic of tourism of families with children with disabilities to propose a conceptual framework of dignity protection for this segment. This framework analyzes the responsibilities of four stakeholders (service providers, government, other tourists, and families) classified into dignity thresholds, to reduce attitudinal, information, and infrastructure barriers faced (...) by children with disabilities and their families when traveling. This paper is one of the few studies that connects the concept of dignity to the family tourism literature (with a special focus on a type of family variation neglected in terms of adequate tourism experiences) through a stakeholder approach focusing on the collaboration among actors within the industry to advance the creation of suitable tourism experiences for families with children with disabilities.

In American ethnic literature of the last three decades of the 20th century, recurrent themes of mobility, travel, and “homing in” are emblematic of the search for identity. In this essay, which discusses three short stories, Alice Walker’s “Everyday Use,” Louise Erdrich’s “The World’s Greatest Fishermen,” and Daniel Chacon’s “The Biggest City in the World,” I attempt to demonstrate that as a consequence of technological development, with travel becoming increasingly accessible to ethnic Americans, their search for identity (...) assumes wider range, transcending national and cultural boundaries.

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 (...) 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.

Ethics of Description: The Anthropological Dispositif and French Modern Travel Writing follows the development of a minor tradition in French literature where metropolitan authors traveling abroad demonstrate their awareness of the ethical conundrums of representing world peoples. During the colonial-modern era, currents of anthropological thought and representational practice are identifiable throughout society, and across literature, the arts, and the sciences. Collectively, they can be theorized as belonging to a dispositif, the anthropological dispositif. The modernization of anthropology serves (...) as an ambivalent interlocutor for the realizations of the writers studied in this book about the difficulties of describing cultural realities that lie largely outside their ken. Anthropology motivates new literary representational strategies that are, alternatively, in keeping with scientific mandates or operate against them. Forty images are analyzed alongside literary works. A postcolonial chapter shows how the ethical awareness of the colonial-modern authors studied have impacted minority self-representation in contemporary France. (shrink)

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.

This idea of time travel has long given philosophers difficulties. Most recently, in his paper ‘Troubles with Time Travel’ William Grey presents a number of objections to time travel, some well known in the philosophical literature, others quite novel. In particular Grey's ‘no destinations’ and ‘double occupation’ objections I take to be original, while what I will call the ‘times paradox’ and the ‘possibility restriction argument’ are versions of well known objections. I show how each of (...) these can be answered, thereby defending the plausibility of time travel. (shrink)

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 contribution explores how Forrester’s work on cases has opened up an arena that might be called ‘the medical case as a travelling genre’. Although usually focused on the course of disease in an individual patient and authored mostly by one medical author, medical case histories have a social dimension: Once published, they often circulate in networks of scholars. Moreover, scholars of the history of literature have shown that numerous medical cases seem to travel easily beyond the context (...) of medical science into the realm of popular literature and journalism. After tracing the idea of cases travelling in Forrester’s Thinking in Cases, I discuss several contributions by authors who, in the wake of interdisciplinary research on cases in the past two decades, have dealt in different ways with this idea. In the third section, I present my own research on a case of self-crucifixion that was widely discussed in 19th-century Europe. I suggest that understanding the case as a ‘traveling genre’ – an expression borrowed from literary genre theory – highlights the role of readers and publication formats as constitutive for cases, and enables us to see more clearly what cases do for scientists and writers who work with them.

The traveling salesman problem is one of the most important issues in combinatorial optimization problems that are used in many engineering sciences and has attracted the attention of many scientists and researchers. In this issue, a salesman starts to move from a desired node called warehouse and returns to the starting place after meeting n customers provided that each customer is only met once. The aim of this issue is to determine a cycle with a minimum cost for this salesman. (...) One of the major weaknesses of the PSO algorithm in the classical version is that it gets stuck in local optimizations. Therefore, in the proposed algorithm, called MPSO, the best solution in the current iteration is also used in the movement step. In addition, a variety of local search algorithms are provided that are used when better answers are generated than before. Also, a new method for moving the particle towards the best particle is presented, which, in addition to probably increasing the quality of the new answer, prevents the premature convergence of the algorithm due to consideration of the concept of random. The results evaluated with the results of several metaheuristic algorithms in the literature show the efficiency of the MPSO algorithm because it has been able to achieve excellent solutions in most of these instances.

Notoriously, the Einstein equations of general relativity have solutions in which closed timelike curves occur. On these curves time loops back onto itself, which has exotic consequences: for example, traveling back into one's own past becomes possible. However, in order to make time travel stories consistent constraints have to be satisfied, which prevents seemingly ordinary and plausible processes from occurring. This, and several other "unphysical" features, have motivated many authors to exclude solutions with CTCs from consideration, e.g. by conjecturing (...) a chronology protection law. In this contribution we shall investigate the nature of one particular class of exotic consequences of CTCs, namely those involving unexpected cases of indeterminism or determinism. Indeterminism arises even against the backdrop of the usual deterministic physical theories when CTCs do not cross spacelike hypersurfaces outside of a limited CTC-region|such hypersurfaces fail to be Cauchy surfaces. We shall compare this CTC-indeterminism with four other types of indeterminism that have been discussed in the philosophy of physics literature: quantum indeterminism, the indeterminism of the hole argument, non-uniqueness of solutions of differential equations and lack of predictability due to insuffcient data. By contrast, a certain kind of determinism appears to arise when an indeterministic theory is applied on a CTC: things cannot be different from what they already were. Again we shall make comparisons, this time with other cases of determination in physics. We shall argue that on further consideration both this indeterminism and determinism on CTCs turn out to possess analogues in other, familiar areas of physics. CTC- indeterminism is close to the epistemological indeterminism we know from statistical physics, while the "fixedness" typical of CTC-determinism is pervasive in physics. CTC- determinism and CTC-indeterminism therefore do not provide incontrovertible grounds for rejecting CTCs as conceptually inadmissible. (shrink)
