Human exploration of space contains many ethical challenges. Future long-term space missions will generate specific problems and place new demands on humanity. One of them is the concept of human enhancement, primarily through gene editing, for the implementation of long-term space missions. This book hypothesizes that large-scale application of human enhancement may be necessary to enable space exploration and exploitation. The book discusses the many arguments for and against human genetic modification for space missions. It (...) also considers the most controversial type of modification, germline gene editing, and presents many arguments in favor of applying even radical and considered controversial forms of human enhancements today. The book shows that the environment of future space missions is a unique and different ethical environment from Earth’s and requires a modified bioethical approach. The bioethics of space missions should be syncretic, issue-driven, and highly dependent on the purpose of space missions. The book points out the importance of discussing future scenarios of human development. Space bioethics is presented as part of futures studies. The book considers futures of humanity in space that are possible, probable, preferable, but also dystopian. The aim of these considerations is to prevent the development of these worst-case scenarios. The book suggests that we should look to the development of biomedicine with greater optimism and hope. Human enhancement via gene editing for space missions is presented as a pragmatic tool rooted in the principle of well-being. (shrink)

Maurice Blanchot, the eminent literary and cultural critic, has had a vast influence on contemporary French writers—among them Jean Paul Sartre and Jacques Derrida. From the 1930s through the present day, his writings have been shaping the international literary consciousness. The Space of Literature, first published in France in 1955, is central to the development of Blanchot's thought. In it he reflects on literature and the unique demand it makes upon our attention. Thus he explores the process of reading (...) as well as the nature of artistic creativity, all the while considering the relation of the literary work to time, to history, and to death. This book consists not so much in the application of a critical method or the demonstration of a theory of literature as in a patiently deliberate meditation upon the literary experience, informed most notably by studies of Mallarme;, Kafka, Rilke, and Hölderlin. Blanchot's discussions of those writers are among the finest in any language. (shrink)

This paper extends implication-space semantics to include first-order quantification. Implication-space semantics has recently been introduced as an inferentialist formal semantics that can capture nonmonotonic and nontransitive material inferences. Extant versions, however, include only propositional logic. This paper extends the framework so as to recover classical first-order logic. The goal is to formulate a theory in which consequence relations can be nonmonotonic and supraclassical, while obeying the deduction-detachment theorem and disjunction simplification, while also including conjunctions that behave multiplicatively as (...) premises and counterexamples to the usual quantifier rules. The paper explains these constraints and shows how they can be met jointly. The result is a first-order version of implication-space semantics that has all the virtues for which inferentialists and inferential expressivists praise propositional implication-space semantics.

Marking a ground-breaking moment in the debate surrounding bodies and "body politics," Elizabeth Grosz's Space, Time and Perversion contends that only by resituating and rethinking the body will feminism and cultural analysis effect and unsettle the knowledges, disciplines and institutions which have controlled, regulated and managed the body both ideologically and materially. Exploring the fields of architecture, philosophy, and--in a controversial way--queer theory, Grosz shows how these fields have conceptually stripped bodies of their specificity, their corporeality, and the vestigal (...) traces of their production as bodies. Her tour de corpe investigates the work of Michel Foucault, Teresa de Lauretis, Gilles Deleuze, Judith Butler and Alphonso Lingis. Grosz considers their work by examining the ways in which the functioning of bodies transforms understandings of space and time, knowledge and desire. Begining with an exposition of the epistemological implications of bodily and sexual difference, Grosz examines the effects such knowledge have on the reception of meaning. She looks at the relationship between the knowledge of difference and the way that knowledge validates, affirms, avows and valorizes subjects. Grosz then extends this analysis to an investigation of the relationship between space, time, bodies and the spatial "arts" such as architecuture, urban planning and geography. In the last section, Grosz moves toward a radical consideration of bodies and their relationship to transgression and perversity. Controversially showing the ways in which "queer" theory fails to offer a truly transformative conception of bodies and their politics, Grosz finds "queer" a reactive category "which sees itself in opposition to a straight norm and thus defines itself in terms of this norm." Consequentially, "queer" theory inherits the acceptance of an entire range of sexual practices, without "asking what they share and without taking into account the profound tension that may exist among these practices." Grosz's Space, Time and Perversity is a diverse and incisive collection of essays from a renowned feminist philosopher. (shrink)

It is argued that Minkowski space-time cannot serve as the deep structure within a ``constructive'' version of the special theory of relativity, contrary to widespread opinion in the philosophical community.

Many organisms possess multiple sensory systems, such as vision, hearing, touch, smell, and taste. The possession of multiple ways of sensing the world offers many benefits. However, combining information from different senses also poses many challenges for the nervous system. In recent years there has been dramatic progress in understanding how information from the different senses gets integrated in order to construct useful representations of external space. This volume brings together the leading researchers from a broad range of scientific (...) approaches to present the first overview of this central topic in cognitive neuroscience. (shrink)

ARARA is a notional space telescope concept whose primary differentiator is onboard early-warning: the payload is paired with flight software that continuously monitors present-time relational stability in its photometric streams to anticipate imminent astrophysical transients (e.g., the earliest moments of a core-collapse supernova) and autonomously retask observations to capture the near-t0 onset with minimal latency. -/- Unlike conventional astrophysical pipelines that are optimized for post-facto detection in downlinked data, ARARA emphasizes in-situ stability monitoring, cross-confirmation between telescopes/lines-of-sight, and closed-loop false-positive (...) control under harsh instrument conditions (gaps, saturation, pointing jitter, and heavy-tailed spurious events). -/- ARARA is explicitly designed to operate either as a single spacecraft (standalone/SOLO mode) or as a low-cost flock/constellation of identical units that exchange compact, audit-friendly event capsules and health beacons over intermittent crosslinks to enable multi-angle confirmation and coordinated follow-up while preserving full autonomy when isolated.

In this paper I present the Discrete Space-Time Thesis, in a way which enables me to defend it against various well-known objections, and which extends to the discrete versions of Special and General Relativity with only minor difficulties. The point of this presentation is not to convince readers that space-time really is discrete but rather to convince them that we do not yet know whether or not it is. Having argued that it is an open question whether or (...) not space-time is discrete, I then turn to some possible empirical evidence, which we do not yet have. This evidence is based on some slight differences between commonly occurring differential equations and their discrete analogs. (shrink)

The paper gives a physicist's view on the framework of branching space-time, 385--434). Branching models are constructed from physical state assignments. The models are then employed to give a formal semantics for the modal operators ``possibly'' and ``necessarily'' and for the counterfactual conditional. The resulting formal language can be used to analyze quantum correlation experiments. As an application sketch, Stapp's premises LOC1 and LOC2 from his purported proof of non-locality, 300--304) are analyzed.

This article attempts to develop the abandoned occasionalist model of causation into a credible present-day theory. If objects can never exhaust one another through their relations, it is hard to know how they can ever interact at all. This article handles the problem by dividing objects into two kinds: the real objects that emerge from Heidegger’s tool-analysis and the intentional objects of Husserl’s phenomenology. Each of these objects turns out to be split by an additional rift between the object as (...) an enduring unit and its plurality of traits. This explains Heidegger’s notorious ‘fourfold’ model of the thing. This article shows that Heidegger’s Geviert must be reinterpreted as a system of four tensions that can be identified as time, space, essence, and eidos. Time and space can no longer be left as peerless dimensions of the cosmos. Instead, they are shown to arise from the tensions between things and their qualities. And for this reason they are joined by essence (in the classical sense of the term) and eidos (in Husserl’s sense, not Plato’s) as two out of four basic features of the fabric of the world. (shrink)

Greenberger. Horne. Shimony, and Zeilinger gave a new version of the Bell theorem without using inequalities (probabilities). Mermin summarized it concisely; but Bohm and Hiley criticized Mermin's proof from contextualists' point of view. Using the branching space-time language, in this paper a proof will be given that is free of these difficulties. At the same time we will also clarify the limits of the validity of the theorem when it is taken as a proof that quantum mechanics is not (...) compatible with a deterministic world nor with a world that permits correlated space-related events without a common cause.

In this paper I challenge the usual interpretations of Newton's and Leibniz's views on the nature of space and the relativity of motion. Newton's ‘relative space’ is not a reference frame; and Leibniz did not regard space as defined with respect to actual enduring bodies. Newton did not subscribe to the relativity of intertial motions; whereas Leibniz believed no body to be at rest, and Newton's absolute motion to be a useful fiction. A more accurate rendering of (...) the opposition between them, I argue, leads to a wholly different understanding of Leibniz's theory of space, one which is not susceptible to the objections Newton had raised against Descartes regarding the representation of motion. This in turn suggests a new approach for contemporary theory of space, one which neither hypostatizes space nor tries to reduce it to relations among actual things. * This work was generously supported by the National Endowment for the Humanities, with a Fellowship for College Teachers and Independent Scholars (FB-26897-89), and also by a sabbatical leave from my institution, Middlebury College.

Super-substantivalism is the thesis that space is identical to matter; it is currently under discussion ? see Sklar (1977, 221?4), Earman (1989, 115?6) and Schaffer (2009) ? in contemporary philosophy of physics and metaphysics. Given this current interest, it is worth investigating the thesis in the history of philosophy. This paper examines the super-substantivalism of Samuel Alexander, an early twentieth century metaphysician primarily associated with (the movement now known as) British Emergentism. Alexander argues that spacetime is ontologically fundamental and (...) it gives rise to an ontological hierarchy of emergence, involving novel properties such as matter, life and mind. Alexander's super-substantivalism is interesting not just because of its historical importance but also because Alexander unusually attempts to explain why spacetime is identical to matter. This paper carefully unpacks that explanation and shows how Alexander is best read as conceiving of spacetime as a Spinozistic substance, worked upon by evolution. (shrink)

Mature representations of number are built on a core system of numerical representation that connects to spatial representations in the form of a ‘mental number line’. The core number system is functional in early infancy, but little is known about the origins of the mapping of numbers onto space. Here we show that preverbal infants transfer the discrimination of an ordered series of numerosities to the discrimination of an ordered series of line lengths. Moreover, infants construct relationships between individual (...) numbers and line lengths that vary positively, but not between numbers and lengths that vary inversely. These findings provide evidence for an early developing predisposition to relate representations of numerical magnitude and spatial length. A central foundation of mathematics, science and technology therefore emerges prior to experience with language, symbol systems, or measurement devices. (shrink)

Earman and Norton argue that manifold realism leads to inequivalence of Leibniz-shifted space-time models, with undesirable consequences such as indeterminism. I respond that intrinsic axiomatization of space-time geometry shows the variant models to be isomorphic with respect to the physically meaningful geometric predicates, and therefore certainly physically equivalent because no theory can characterize its models more closely than this. The contrary philosophical arguments involve confusions about identity and representation of space-time points, fostered by extrinsic coordinate formulations and (...) irrelevant modal metaphysics. I conclude that neither the revived Einstein hole argument nor the original Leibniz indiscernibility argument have any force against manifold realism. (shrink)

The Nature of Space is a translation of pioneering geographer Milton Santos' A Natureza do Espaço, originally published in Brazil in 1996. The book offers a theory of human space based on relationships between time and ontology, producing a system of ideas that can catalyze a descriptive and interpretive system of geography. Santos argues that when geographers consider the inseparability of time and space, they can then transcend fragmented realities and partial truths without trying to philosophize or (...) theorize their way around them. Based on these premises, The Nature of Space seeks to examine the role of space, defined as indissoluble systems of objects and systems of actions in social processes, and provide a geographic contribution to the production of a critical social theory.

Around the turn of the century, Poincare and Hilbert each published an account of geometry that took the discipline to be an implicit definition of its concepts. The terms ‘point’, ‘line’, and ‘plane’ can be applied to any system of objects that satisfies the axioms. Each mathematician found spirited opposition from a different logicist—Russell against Poincare' and Frege against Hilbert— who maintained the dying view that geometry essentially concerns space or spatial intuition. The debates illustrate the emerging idea of (...) mathematics as the science of structure. The article closes with some remarks on structuralist and nonstructuralist themes in Frege's own development of arithmetic. (shrink)

Over a decade ago, I introduced a large-scale theory of the cognitive brain which explained for the first time how the human brain is able to create internal models of its intimate world and invent models of a wider universe. An essential part of the theoretical model is an organization of neuronal mechanisms which I have named the Retinoid Model (Trehub, 1977, 1991). This hypothesized brain system has structural and dynamic properties enabling it to register and appropriately integrate disparate foveal (...) stimuli into a perspectival, egocentric representation of an extended 3D world scene including a neuronally-tokened locus of the self which, in this theory, is the neuronal origin of retinoid space. As an integral part of the larger neuro-cognitive model, the retinoid system is able to perform many other useful perceptual and higher cognitive functions. In this paper, I draw on the hypothesized properties of this system to argue that neuronal activity within the retinoid structure constitutes the phenomenal content of consciousness and the unique sense of self that each of us experiences. -/- Trehub, A.

Prompted by the "Panel Discussion of Grünbaum's Philosophy of Science" (Philosophy of Science 36, December, 1969) and other recent literature, this essay ranges over major issues in the philosophy of space, time and space-time as well as over problems in the logic of ascertaining the falsity of a scientific hypothesis. The author's philosophy of geometry has recently been challenged along three main distinct lines as follows: (i) The Panel article by G. J. Massey calls for a more precise (...) and more coherent account of the Riemannian conception of an intrinsic as opposed to an extrinsic metric, which the author has invoked as his basis for the distinction between non-conventional and convention-laden ascriptions of metrical equality and inequality; (ii) the latter distinction has been claimed to suffer from the liabilities of the so-called "standard conception" of scientific theories [36]; and (iii) pursuant to H. Putnam's "An Examination of Grünbaum's Philosophy of Geometry" [56], J. Earman [16, 17] and R. Swinburne [65] have contended that the difference between intrinsic and extrinsic metrics is scientifically unilluminating, and that the associated distinction between non-conventional and convention-laden metrical comparisons does not have the kind of relevance to extant scientific theories that the author has claimed for it. The essay consists of two installments. The present installment, comprising the Introduction and Part A, is devoted to the clarification, correction and further development of the author's prior writings on the philosophy of geometry. Its main objective is constructive elaboration rather than offering polemics. But rebuttals to Earman, [16, 17], Swinburne [65] and Demopoulos [13] are included, because their inclusion conduced to clarity in giving the new exposition. Part B is to appear in a subsequent issue and will be devoted to replies to critiques contained in the Panel Discussion and in other recent literature. It will range over issues in the philosophy of geometry and in the logic of ascertaining the falsity of a scientific hypothesis. By way of merely elliptical anticipation of much more precise statements given in Part A, section 3(ii), the Introduction dissociates the notion of convention-ladenness developed in Part A from the quite different notion integral to the so-called "standard conception" of scientific theories. Thereby, the Introduction prepares the ground for seeing, as a corollary to Part A, section 3(ii), that the notion advocated in the present essay has nothing to fear from the following fact, noted by C. G. Hempel ([36]; cf. also his 1970 Carus Lectures): "even though a sentence may originally be introduced as true by stipulation, it soon joins the club of all other member-statements of the theory and becomes subject to revision in response to further empirical findings and theoretical developments." Part A, which begins with a fairly detailed table of contents, endeavors to meet the aforementioned three-fold challenge to the author's philosophy of geometry. Massey's call for the provision of clear and detailed characterizations of intrinsic and extrinsic metrics is answered with the invaluable aid rendered personally by Massey himself. These characterizations are shown to permit a precise explication of the portions of Riemann's Inaugural Dissertation relevant to (1) Riemann's brilliant anticipation of Einstein's dynamical conception of physical geometry, and (2) the author's philosophical characterization of the metrics and geometries of space, time, and space-time {section 2(c)}. A byproduct of the analysis is to raise two major philosophical doubts concerning Clifford's sketch of a so-called "space-theory of matter" as elaborated in J. A. Wheeler's relativistic geometrodynamics. That theory's vision of understanding matter as a manifestation of empty curved space is questioned in regard to (1) the existence of an intra-geometrodynamic basis for individuating the metrically homogeneous world points of its space-time manifold {section 1(a)}, and (2) the compatibility of the theory with the Riemannian metrical philosophy apparently espoused by its proponents {section 2(c)(i)}.

Learning through original texts can be a powerful heuristic tool. This book collects a dozen classic readings that are generally accepted as the most significant contributions to the philosophy of space. The readings have been selected both on the basis of their relevance to recent debates on the nature of space and on the extent to which they carry premonitions of contemporary physics. In his detailed commentaries, Nick Huggett weaves together the readings and links them to our modern (...) understanding of the subject. Together the readings indicate the general historical development of the concept of space, and in his commentaries Huggett explains their logical relations. He also uses our contemporary understanding of space to help clarify the key ideas of the texts. One goal is to prepare the reader (both scientist and nonscientist) to learn and understand relativity theory, the basis of our current understanding of space. The readings are by Zeno, Plato, Aristotle, Euclid, Descartes, Newton, Leibniz, Clarke, Berkeley, Kant, Mach, Poincaré, and Einstein. (shrink)

In this paper I will outline a unified information processing framework whose goal is to explain how the nervous system represents space, time and objects.

Is synaesthesia cognitively useful? Individuals with time–space synaesthesia experience time units as idiosyncratic spatial forms, and report that these forms aid them in mentally organising their time. In the present study, we hypothesised that time–space synaesthesia would facilitate performance on a time-related cognitive task. Synaesthetes were not specifically recruited for participation; instead, likelihood of time–space synaesthesia was assessed on a continuous scale based on participants’ responses during a semi-structured interview. Participants performed a month-manipulation task, which involved naming (...) every second month or every third month in reverse-chronological order, beginning and ending with a target month. Using hierarchical multiple regression, we found that time–space synaesthesia corresponded with faster performance on both versions of the task. We propose that time–space synaesthesia may expedite the cognitive manipulation of time-based information. Our results also indicate that synaesthesia is far less unusual than widely believed.

New discoveries about materials and solar energy raise the possibility of a long-tenn shift of mining, refining, and manufacturing from Earth’s surface to locations outside Earth’s ecosphere, allowing Earth to begin to relax back toward its natural state. A little-discussed ambivalence toward the potential of space exploration exists among environmentalists. One camp sees it as a human adventure that may allow a bold initiative to improve Earth; another camp shies away from “heavy technology” and thus distrusts efforts as massive (...) as space exploration or utilization. Due to impending resource depletion on Earth, we may have only until the mid-twenty-first century to pursue the promising potential of space exploration to alleviate environmental problems of Earth. Subsequently, there may be too litde industlial base to support vigorous exploration and exploitation of resources in space. (shrink)

The value of a negatively defined private space is defended as important for the development of personal autonomy. It is argued that negative liberty is problematic when split off from its connection with this ideal. An ethical interpretation of personal autonomy is proposed according to which a private space is one of autonomy's preconditions. This leads to a conceptualization of privacy that is fruitful in two respects: it permits an account of privacy laws that avoids certain pitfalls, and (...) it serves as a basis for criticizing privacy-related failures of autonomy together with the social forces that produce them. Negative liberty is, furthermore, rejected as an adequate basis for modern law and democracy. Here, too, an ethically defined personal autonomy, of which negative liberty is a precondition, is held to be the most convincing normative foundation. A critical reading of Habermas' cooriginality thesis is offered in support of this argument. Key Words: cooriginality thesis • Jürgen Habermas • Herbert Marcuse • negative liberty • personal autonomy • positive liberty • privacy • Martin Walser. (shrink)

A definition is proposed to give precise meaning to the counterfactual statements that often appear in discussions of the implications of quantum mechanics. Of particular interest are counterfactual statements which involve events occurring at space-like separated points, which do not have an absolute time ordering. Some consequences of this definition are discussed.

I argue that when empty space is seen in mirrors—that is, when perceptual specular experience is veridical—specular empty space is, like pictorial empty space, seen-in. I explain how the phenomenal expansiveness of specular reflections can nonetheless be reconciled with the see-through look of specular space.

Hannah Arendt’s notion of public space is one of her most fruitful, yet frustrating concepts. Having employed it to analyze political freedom, she claims that such space has largely disappeared in the modern world. In what follows, I am going to argue that this pessimistic assessment follows from Arendt’s exclusion of labor and work from the public realm. Against Arendt’s claim that such activities are essentially private, I shall argue that they, like action, manifest our embodied being-in-the-world. When (...) we think of public space in terms of our embodied presence, it becomes a concept applicable to modern democratic politics. (shrink)

This is an interdisciplinary volume that focuses on the central topic of the representation of events, namely cross-cultural differences in representing time and space, as well as various aspects of the conceptualisation of space and time.

In this paper recognition is taken to be a question of social ontology, regarding the very constitution of the social space of interaction. I concentrate on the question of whether certain aspects of the theory of recognition can be translated into the terms of a socio-ontological paradigm: to do so, I make reference to some conceptual tools derived from John Searle's social ontology and Robert Brandom's normative pragmatics. My strategy consists in showing that recognitive phenomena cannot be isolated at (...) the level of human interaction, and are, rather, in part proper to animal interaction as well. Furthermore, it is argued that recognitive powers are constitutive powers more basic than deontic ones and play a role much broader than the one they in fact assume in Searle and in Brandom.

Human interaction and communication involve space in multiple ways. This paper examines the spatial and interactional order of a covertly video-taped police interrogation. When the participants enter the interrogation room and become engaged in the interrogation process, the room itself is a constraint and a resource for interaction. While interacting within a built environment, the participants appropriate their material surroundings in ways that constitute a spatial order and make possible certain arguments. This paper examines how the physical structure of (...) the interrogation room is differentially appropriated, used, and filled in by the participants''; territorial and postural manoeuvers over the course of their interaction; and how the spatial structures thus created by the bodily appropriation of the physical locale are subsequently formulated by talk and thereby used as a metaphorical resource to frame the participants'' situated experience. Through this embedded process, the interrogators move the suspect toward confession. (shrink)

Who can penetrate space or encounter the stream of time? Only those who are not fooled into believing that freedom from sensory conditions is attainable by moving beyond a space and a time considered real because of their measurability. The reality of time and space is immeasurable. It cannot be attained by overcoming the given forms of measurement, but rather by overcoming measurement itself. Before this can occur, we must know how and why measurement arises; we must (...) know what the spirit wants by containing within measurement the substance of its eternal telling of tales, whose truth alone justifies measurement--the transitory vision of what space and time are in their most subtle forms. This masterly book by Massimo Scaligero--author of The Light (La Luce): An Introduction to Creative Imagination--teaches us how to enter and recognize the spiritual reality behind and within what we objectify as space and time. Those who read The Secrets of Space and Time with meditative effort will be well rewarded with profound insights about the true nature of the world around us. The book is a translation from Italian of Segreti dello spazio e del tempo (Libreria Tilopa, Rome, 1963). (shrink)

This paper is concerned with the conceptualisations of space which underlie debate of gentrification-related displacement. Using Derrida's concept of the spatial metaphor, the paper illuminates the Cartesian understandings of space that act as architecture for displacement debate. The paper corrects this through arguing that the philosophy of Heidegger and Lefebvre better serves to understand displacement. Emphasising the topology of Heidegger's Dasein and, following Elden, relating this to Lefebvre's understanding of space, the paper 'constructs' displacement in a way (...) that avoids the abstraction of displacement-as-out-migration and instead emphasises the lived experience of space.

The purpose of this paper is twofold: a) to explore the compatibility of Minkowski’s space-time representation of the Special theory of relativity with a dynamic conception of space-time; b) to locate its roots in invariant features - like entropic relations - of the propagation of signals in space-time. From its very beginning Minkowski’s four-dimensional space-time was associated with a static view of reality, e.g. a block universe. Einstein added his influential voice to this conception when he (...) wrote: ‘From a “happening” in three-dimensional space, physics becomes (…) an “existence” in the four-dimensional “world”.’ (Einstein, Relativity 1920, 122) Yet it is by no means clear that Minkowski himself was a believer in the block universe. In his 1908 Cologne lecture on ‘Space and Time’ he speaks of a four-dimensional physics but concedes that a ‘necessary’ time order can be established at every world point. Although the conception of the block universe has gained much currency, an alternative view has been in circulation since the 1910s according to which the trajectories of particles constitute histories in space-time.

I would like to thank Dr. Gabaccia for her intriguing essay on the origins of the term "nation of immigrants." It really has helped me think about immigration with more historical richness.

Going against perhaps unidirectional ways of understanding the immigrant as a foreigner entering into a country, I understand the immigrant identity (...) within a transnational framework where the immigrant negotiates between more than one country. In my larger work, I want to look at the space-between that emerges for many immigrants and. (shrink)

In this paper I challenge the common view that early in his career (1679-1695) Leibniz held that space and time are well-founded phenomena, entities on an ontological par with bodies and their properties. I argue that the evidence Leibniz ever held that space and time are well-founded phenomena is extremely weak and that there is a great deal of evidence for thinking that in the 1680s he held a position much like the one scholars rightly attribute to him (...) in his mature period, namely, that space and time are merely orders of existence and as such are purely abstract and occupy an ontological realm distinct from that of well-founded phenomena. In the course of arguing for this interpretation, I offer an account of the nature of Leibnizian phenomena which allows Leibniz to hold the view that space and time are phenomena, while at the same time thinking of them as abstract, ideal orders of existence.
