How do engineers respond to ethical dilemmas that occur in practice? How do they view their individual and collective responsibilities? How do they make decisions before all the facts are in? Using the space shuttle programme as the framework, this book examines the role of ethical decision making in the practice of engineering. In particular, the book considers the design and development of the main engines of the space shuttle as a paradigm for how individual engineers perceive, articulate, and resolve (...) ethical dilemmas in a large, complex organisation. A series of in-depth case studies show engineers at work on various stages of the project as they balance budgets, deadlines and risks. By documenting the historical development of a single system, the book provides a unique opportunity to explore the complex interactions between political, organisational and technical pressures and engineering and management decisions.

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.

This is a revised and updated edition of Graham Nerlich's classic book The Shape of Space. It develops a metaphysical account of space which treats it as a real and concrete entity. In particular, it shows that the shape of space plays a key explanatory role in space and spacetime theories. Arguing that geometrical explanation is very like causal explanation, Professor Nerlich prepares the ground for philosophical argument, and, using a number of novel examples, investigates how different spaces would affect (...) perception differently. This leads naturally to conventionalism as a non-realist metaphysics of space, an account which Professor Nerlich criticises, rejecting its Kantian and positivistic roots along with Reichenbach's famous claim that even the topology of space is conventional. He concludes that there is, in fact, no problem of underdetermination for this aspect of spacetime theories, and offers an extensive discussion of the relativity of motion. (shrink)

This paper offers a comparative study of abnormalities in the experience of space, time, and general atmosphere in three psychiatric conditions: schizophrenia, melancholia, and mania. It is a companion piece to our previous article entitled 'Varieties of Self- Experience'; here we focus on experiences of the world rather than of the self. As before, we are especially interested in similarities but also in some subtle distinctions in the forms of subjectivity associated with these three conditions. As before, we survey phenomenologicallyoriented (...) clinical and theoretical accounts as well as patient reports. Experiences involving forms of alienation from the practical and social world and a sense of uncanniness seem to be common in both schizophrenia and affective disorders. But despite some significant similarities, changes in schizophrenic subjectivity appear to be more pervasive and profound, involving experiences of fragmentation, meaninglessess, and ineffable strangeness that are rare or absent in the affective disorders.

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)

There is an analogy between Timaeus's act of describing a world in words and the demiurge's task of making a world of matter. This analogy implies a parallel between language as a system of reproducing ideas in words, and the world, which reproduces reality in particular things. Authority lies in the creation of a likeness in words of the eternal Forms. The Forms serve as paradigms both for the physical world created by the demiurge, and for the world in discourse (...) created by Timaeus: his discourse gains its validity not from faithfulness to the way things appear, or the way particular things 'actually happened', but in virtue of its attempt to express in words a likeness of the perfect and eternal reality. There are implications for Plato's philosophy of language, and for the relation between words and things (words do not depict or name things but can be used to construct worlds in a parallel way to the manner in which things construct worlds, both worlds being modelled on one common world of ideas). The match between world and discourse is because of their common pictorial relation (likeness) to an independent model. (shrink)

Many scholars have drawn attention to the way that elements of Anne Conway’s system anticipate ideas found in Leibniz. This paper explores the relationship between Conway and Leibniz’s work with regard to time, space, and process. It argues – against existing scholarship – that Conway is not a proto-Leibnizian relationist about time or space, and in fact her views lie much closer to those of Henry More; yet Conway and Leibniz agree on the primacy of process. This exploration advances our (...) understanding of Conway’s system, and the intellectual relationships between Conway, More, and Leibniz. (shrink)

Hermann von Helmholtz’s geometrical papers have been typically deemed to provide an implicitly group-theoretical analysis of space, as articulated later by Felix Klein, Sophus Lie, and Henri Poincaré. However, there is less agreement as to what properties exactly in such a view would pertain to space, as opposed to abstract mathematical structures, on the one hand, and empirical contents, on the other. According to Moritz Schlick, the puzzle can be resolved only by clearly distinguishing the empirical qualities of spatial perception (...) from those describable in terms of axiomatic geometry. This paper offers a partial defense of the group-theoretical reading of Helmholtz along the lines of Ernst Cassirer in the fourth volume of The Problem of Knowledge of 1940. In order to avoid the problem raised by Schlick, Cassirer relied on a Kantian view of space not so much as an object of geometry, but as a precondition for the possibility of measurement. Although the concept of group does not provide a description of space, the modern way to articulate the concept of space in terms of transformation groups reveals something about the structure and the transformation of spatial concepts in mathematical and natural sciences.

Helmholtz's theory of space had significant impact on Schlick's early ?critical realist? point of view. However, it will be argued in this paper that Schlick's appropriation of Helmholtz's ideas eventually lead to a rather radical transformation of the original Helmholtzian position.

Taking ontological realism about social groups as the thesis that groups are composite material objects constituted by their members, this paper considers a challenge to the very possibility that groups be regarded as material entities. Ordinarily we believe that two groups can have synchronic co-extensive memberships—for example, the choir and the rugby team—while preserving their distinctive identity conditions. We also doubt that two objects of the same kind can be in the same place at the same time, which would appear (...) to be the case when groups have identical memberships. I explain that the principle denying the synchronic co-location of objects of the same kind need not apply universally to material objects and that it is a mistake to take resistance to penetrability as a necessary feature of materiality. Therefore, initial appearances notwithstanding, groups can be in the same place at the same time. Key Words: identity • materiality • location • social group. (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. In the remainder of this introductory section I will first be more specific about the sort of spatial, temporal, and object representation at issue, and then outline the structure of this paper.

We present a formal derivation of the Mino–Sasaki–Tanaka–Quinn–Wald (MSTQW) equation describing the self-force on a (semi-) classical relativistic point mass moving under the influence of quantized linear metric perturbations on a curved background space–time. The curvature of the space–time implies that the dynamics of the particle and the field is history-dependent and as such requires a non-equilibrium formalism to ensure the consistent evolution of both particle and field, viz., the worldline influence functional and the closed- time-path (CTP) coarse-grained effective action. (...) In the spirit of effective field theory, we regularize the formally divergent self-force by smearing the local part of the retarded Green’s function and employing a quasi-local expansion. We derive the MSTQW–Langevin equations describing the perturbations of the particle’s worldline about its semi-classical trajectory resulting from interactions with the quantum fluctuations of the linear metric perturbations. Finally, we demonstrate that the quantum fluctuations of the field could, in principle, leave imprints on gravitational waveforms expected to be observed by gravitational interferometers, thereby encoding information about tree-level perturbative quantum gravity.

Kant’s cosmopolitanism can be read from two main perspectives: temporal and spatial. Reading cosmopolitanism from a temporal perspective means paying attention to the historical realization of the ideal of cosmopolitanism and to its related issues such as: the progress of humankind, its final destination, the purpose of universal history, the highest purpose of nature. Instead, reading cosmopolitanism from a spatial perspective means paying attention, e.g. to the ‘fact’ of the sphericity of the earth and to its relationship with cosmopolitan right, (...) territoriality, borders and freedom of movement. In this paper I would like to show how adopting a spatial perspective is useful not only in order to delimit a field of inquiry, but also to shed new light on apparently well-known and thoroughly investigated notions of Kant’s cosmopolitanism, such as the notions of the citizen of the world, of the cosmopolitan right, and of the World republic.

The book offers the first analysis of the influence exercised by the concept of space on the emergence and continuing operation of international law. By adopting a historical perspective and analysing work of two central early modern thinkers – Leibniz and Hobbes – it offers a significant addition to a limited range of resources on early modern history of international law. The book traces links between concepts of space, universality, human cognition, law, and international law in these two early modern (...) thinkers in a comparative fashion. Through this analysis, the book demonstrates the dependency of the contemporary international law on the Hobbesian concept of space. Although some Leibnizian elements continue to operate, they are distorted. This continuing operation of Leibnizian elements is explained by the inability of international law, which is based on the Hobbesian concept of space, to ensure universality of its normative foundation.

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)

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.

Recent debates among scholars in Literature education have led to polarizing views about the aims of the subject. The debate reignites ancient quarrels about the aesthetic and political values of literary study and relatedly, the different pedagogical approaches to teaching. In the first part of this paper, I explore the aesthetic-political divide in Literature education paying particular attention to how this was reinforced by New Criticism and Poststructuralist Criticism as these were key movements that have had a significant influence on (...) the teaching of Literature in schools. More importantly, I argue that such a divide exemplified the different goals of the West, in which Literature education originated as a platform for the cultivation of taste, and Postcolonial countries, in which the subject was utilized as a political tool for colonization resulting in acts of mimicry and subversion among colonized subjects. In the second part of the paper, I apply third space theory to disrupt the aesthetic-political divide. I discuss the need to create third spaces in Literature classrooms that are critical, inclusive, negotiated and ethical allowing students to engage with aesthetic, political and ethical dimensions of literature.

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)

With the rising influence of digitalization and its immense penetration intoeven everyday life, the last decade of the 20th Century addressed to a critical threshold in the successive transformation process of the spatiality in its long-term run. The advanced digital technologies of ubiquitous computing and generative design, as well as the invention of smart materials in late 90’s have all provoked the fluid characteristics of spatiality, and strengthen the transformative capacities of the architectural space through the emergence of computer-augmented territories. (...) Additionally, while they are becoming as the body extensions, the advent of novel apparatuses and gadgets further enhanced the inte- gration of the corporal and incorporal bodies with the spatio-temporal multiplicities, where the hyperdimensionality of the space has been triggered to its outmost range, in relation to the “soft and smart technologically augmented immanent millieu”, in Spuybroek terms. Thus, like Spuybroek points out as the “haptonomist” presence of the body merges itself with these diverse bodily extensions on one hand; and on the other hand, as the rising influence of nomadic view of the world further stimulates the unboundedness and endless fluidity of space, so that the spatiality becomes a landscape of successive transformations, a topology of emergence or a plane of becoming, which is merely defined by lines of forces, and occures as an alive territory rather than a limited space of predefined boarders. Therefore, this evolvable territory which is affectable and being affected by the lines of forces –inner and outer forces–, emerges as an animated existence, an interactive organism. So, by interacting with the Deleuzian Philosophy and their notions like lines of forces, folding, becoming, smooth space, territory, spatium, this article aims to reveal the relevance of these notions in architectural discourse, as well as the emergence of the smooth space in the contemporary architectural practice, by magnifiying one of the very initial examples of its kind; in terms of unfolding the Fresh Water Pavilion of NOX Architecture by Lars Spuybroek into question to reveal the essences of thecontemporary transformable-evolvable architectural spatiality.
