In this paper, I undertake a conceptual analysis of ordinary usages of the concepts of “litter” and “pollution.” If “litter” or “pollution” applies to space debris in its various contexts, then in dealing with space debris as an ethical concern, we may more neatly apply arguments for the wrongness of litter and pollution to these new contexts. After engaging in a conceptual analysis of “litter” and “pollution,” I consider whether these concepts apply to space debris, examining three (...) contexts: (1) surface debris on Moon and Mars, (2) intentionally crashing objects into gas giants, ice giants, and stars, and (3) the pressing issue of orbital space debris. I conclude by finding that neither “litter” nor “pollution” cleanly applies to any of these three contexts. (shrink)

Quantum Theory, similar to Relativity Theory, requires a new concept of space-time, imposed by a universal constant. While velocity of lightcnot being infinite calls for a redefinition of space-time on large and cosmological scales, quantization of action in terms of a finite, i.e. non vanishing, universal constanthrequires a redefinition of space-time on very small scales. Most importantly, the classical notion of “time”, as one common continuous time variable and nature evolving continuously “in time”, has to be replaced (...) by an infinite manifold of transition rates for discontinuous quantum transitions. The fundamental laws of quantum physics, commutation relations and quantum equations of motion, resulted from Max Born’s recognition of the basic principle of quantum physics:To each change in nature corresponds an integer number of quanta of action. Action variables may only change by integer values ofh, requiring all other physical quantities to change by discrete steps, “quantum jumps”. The mathematical implementation of this principle led to commutation relations and quantum equations of motion. The notion of “point” in space-time looses its physical significance; quantum uncertainties of time, position, just as any other physical quantity, are necessary consequences of quantization of action.

There is an apparent tension in Shepherd’s accounts of space and time. Firstly, Shepherd explicitly claims that we know that the space and time of the unperceived world exist because they cause our phenomenal experience of them. Secondly, Shepherd emphasizes that empty space and time do not have the power to effect any change in the world. My proposal is that for Shepherd time has exactly one causal power: to provide for the continued existence of self-same or (...) changing objects. Because Shepherd takes causation to be a relation whereby two objects combine to form a third, their effect, whenever we perceive a continually existing object, since time is a proper part of such objects, our perception of time is caused by time itself. Likewise, space’s causal power is to provide for the possibility of the motion or rest of objects, and so when we perceive objects with space as a proper part, we come into causal contact with space.

This paper investigates the significance of T-duality in string theory: the indistinguisha- bility with respect to all observables, of models attributing radically different radii to space – larger than the observable universe, or far smaller than the Planck length, say. Two interpretational branch points are identified and discussed. First, whether duals are physically equivalent or not: by considering a duality of the familiar simple harmonic oscillator, I argue that they are. Unlike the oscillator, there are no measurements ‘outside’ string (...) theory that could distinguish the duals. Second, whether duals agree or disagree on the radius of ‘target space’, the space in which strings evolve according to string theory. I argue for the latter position, because the alternative leaves it unknown what the radius is. Since duals are physically equivalent yet disagree on the radius of target space, it follows that the radius is indeterminate between them. Using an analysis of Brandenberger and Vafa (1989), I explain why – even so – space is observed to have a determinate, large radius. The conclusion is that observed, ‘phenomenal’ space is not target space, since a space cannot have both a determinate and indeterminate radius: instead phenomenal space must be a higher-level phenomenon, not fundamental.

This paper offers a new account of how structural rationality, or coherence, is normative. The central challenge to the normativity of coherence – which I term the problem of “making space” for the normativity of coherence – is this: if considerations of coherence matter normatively, it is not clear how we ought to take account of them in our deliberation. Coherence considerations don’t seem to show up in reasoning about what to believe, intend, desire, hope, fear, and so on; (...) moreover, they seem awkward to take account of alongside more “substantive” considerations about the merits of such attitudes. I aim here to solve this problem, and in so doing to offer the aforementioned new account of how coherence is normative. On the view I defend, which I call the Reasons-to-Structure-Deliberation model, considerations of coherence constitute reasons for structuring deliberation in certain ways: more particularly, to treat incoherent combinations of attitudes as off-limits, and so to focus one’s deliberation on choosing between the coherent combinations.

The purpose of the two studies reported here was to develop an integrated model of the scientific reasoning process. Subjects were placed in a simulated scientific discovery context by first teaching them how to use an electronic device and then asking them to discover how a hitherto unencountered function worked. To do this task, subjects had to formulate hypotheses based on their prior knowledge, conduct experiments, and evaluate the results of their experiments. In the first study, using 20 adult subjects, (...) we identified two main strategies that subjects used to generate new hypotheses. One strategy was to search memory and the other was to generalize from the results of previous experiments. We described the former group as searching an hypothesis space, and the latter as searching an experiment space. In a second study, with 10 adults, we investigated how subjects search the hypothesis space by instructing them to state all the hypotheses that they could think of prior to conducting any experiments. Following this phase, subjects were then allowed to conduct experiments. Subjects who could not think of the correct rule in the hypothesis generation phase discovered the correct rule only by generalizing from the results of experiments in the experimental phase.Both studies provide support for the view that scientific reasoning can be characterized as search in two problem spaces. By extending Simon and Lea's (1974) Generalized Rule Inducer, we present a general model of Scientific Discovery as Dual Search (SDDS) that shows how search in two problem spaces (an hypothesis space and an experiment space) shapes hypothesis generation, experimental design, and the evaluation of hypotheses. The model also shows how these processes interact with each other. Finally, we interpret earlier findings about the psychology of scientific reasoning in terms of the SDDS model. (shrink)

From nineteenth-century abolitionism to Black Lives Matter today, progressive social movements have been at the forefront of social change. Yet it is seldom recognized that such movements have not only engaged in political action but also posed crucial philosophical questions about the meaning of justice and about how the demands of justice can be met. -/- Michele Moody-Adams argues that anyone who is concerned with the theory or the practice of justice—or both—must ask what can be learned from social movements. (...) Drawing on a range of compelling examples, she explores what they have shown about the nature of justice as well as what it takes to create space for justice in the world. Moody-Adams considers progressive social movements as wellsprings of moral inquiry and as agents of social change, drawing out key philosophical and practical principles. Social justice demands humane regard for others, combining compassionate concern and robust respect. Successful movements have drawn on the transformative power of imagination, strengthening the motivation to pursue justice and to create the political institutions and social policies that can sustain it by inspiring political hope. -/- Making Space for Justice contends that the insights arising from social movements are critical to bridging the gap between discerning theory and effective practice—and should be transformative for political thought as well as for political activism.

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.

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)

What if gravity satisfied the Klein-Gordon equation? Both particle physics from the 1920s-30s and the 1890s Neumann-Seeliger modification of Newtonian gravity with exponential decay suggest considering a "graviton mass term" for gravity, which is _algebraic_ in the potential. Unlike Nordström's "massless" theory, massive scalar gravity is strictly special relativistic in the sense of being invariant under the Poincaré group but not the 15-parameter Bateman-Cunningham conformal group. It therefore exhibits the whole of Minkowski space-time structure, albeit only indirectly concerning volumes. (...) Massive scalar gravity is plausible in terms of relativistic field theory, while violating most interesting versions of Einstein's principles of general covariance, general relativity, equivalence, and Mach. Geometry is a poor guide to understanding massive scalar gravity: matter sees a conformally flat metric due to universal coupling, but gravity also sees the rest of the flat metric in the mass term. What is the 'true' geometry, one might wonder, in line with Poincaré's modal conventionality argument? Infinitely many theories exhibit this bimetric 'geometry,' all with the total stress-energy's trace as source; thus geometry does not explain the field equations. The irrelevance of the Ehlers-Pirani-Schild construction to a critique of conventionalism becomes evident when multi-geometry theories are contemplated. Much as Seeliger envisaged, the smooth massless limit indicates underdetermination of theories by data between massless and massive scalar gravities---indeed an unconceived alternative. At least one version easily could have been developed before General Relativity; it then would have motivated thinking of Einstein's equations along the lines of Einstein's newly re-appreciated "physical strategy" and particle physics and would have suggested a rivalry from massive spin 2 variants of General Relativity. The Putnam-Grünbaum debate on conventionality is revisited with an emphasis on the broad modal scope of conventionalist views. Massive scalar gravity thus contributes to a historically plausible rational reconstruction of much of 20th-21st century space-time philosophy in the light of particle physics. An appendix reconsiders the Malament-Weatherall-Manchak conformal restriction of conventionality and constructs the 'universal force' influencing the causal structure. Subsequent works will discuss how massive gravity could have provided a template for a more Kant-friendly space-time theory that would have blocked Moritz Schlick's supposed refutation of synthetic _a priori_ knowledge, and how Einstein's false analogy between the Neumann-Seeliger-Einstein modification of Newtonian gravity and the cosmological constant \Lambda generated lasting confusion that obscured massive gravity as a conceptual possibility.

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)

This paper argues that a common form of representationalism has trouble accommodating empirical findings about visual space perception. Vision science tells us that the visual system systematically gives rise to different experiences of the same spatial property. This, combined with a naturalistic account of content, suggests that the same spatial property can have different veridical looks. I use this to argue that a common form of representationalism about spatial experience must be rejected. I conclude by considering alternatives to this (...) view. (shrink)

Textbooks present classical particle and field physics as theories of physical systems situated in Newtonian absolute space. This absolute space has an influence on the evolution of physical processes, and can therefore be seen as a physical system itself; it is substantival. It turns out to be possible, however, to interpret the classical theories in another way. According to this rival interpretation, spatiotemporal position is a property of physical systems, and there is no substantival spacetime. The traditional objection (...) that such a relationist view could not cope with the existence of inertial effects and other manifestations of the causal efficacy of spacetime can be answered successfully. According to the new point of view, the spacetime manifold of classical physics is a purely representational device. It represents possible locations of physical objects or events; but these locations are physical properties inherent in the physical objects or events themselves and having no existence independently of them. In relativistic quantum field theory the physical meaning of the spacetime manifold becomes even less tangible. Not only does the manifold lose its status as a substantival container, but also its function as a representation of spacetime properties possessed by physical systems becomes problematic. 'Space and time' become ordering parameters in the web of properties of physical systems. They seem to regain their traditional meaning only in the non-relativistic limit in which the classical particle concept becomes approximately applicable. (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.

A general sketch on how the problem of space dimensionality depends on anthropic arguments is presented. Several examples of how life has been used to constraint space dimensionality (and vice-versa) are reviewed. In particular, the influences of three-dimensionality in the solar system stability and the origin of life on Earth are discussed. New constraints on space dimensionality and on its invariance in very large spatial and temporal scales are also stressed.

This paper intends to illustrate the monuments of the Periklean building programme as embodying acts of temporal configuration; organizing synoptic episodes into an ethno-cultural continuum. A required element to this process is the issue of space, both in its experienced and imagined aspects, as the framework by which temporality is fixed and recounted. By viewing the monuments and accompanying iconography as spatio-temporal configurations, we can see the generation of those elements necessary for the formation of cultural identity via memory. (...) This includes the provision of axial points in time, set in space and wider temporal chronologies, and the election of totemic, and semioticized personages. Moreover, as the configurative action is both framed and informed by its enunciative context, the monuments indicate the promotion of biographical memory, as relating to the Persian Wars, into the register of Athenian cultural memory and temporality.

Evaluation processes are a basic component of creativity. They guide not only the pure judgement about a new artefact but also the generation itself, as creators constantly evaluate their own work.

A theoretical model and (...) its implementation are explained and validation of the evaluation function through comparison with human criteria is described. (shrink)

Mirko Garasic (2021) argued that space travel and, by extension, the colonization of other planets could morally justify using technologies and interventions capable of profoundly modifying the characteristics of astronauts and future Martian generations. According to Garasic, however, the fact that space interventions such as human (bio)enhancement or reproductive technologies such as artificial wombs may be morally justified does not mean that they are morally acceptable technologies to be used on Earth as well. Garasic’s thesis is that we (...) should resist the temptation to establish or reinforce a continuity between the ethical standards that apply to space travel and those that apply on Earth because what applies in space (or on other planets) does not necessarily apply to our planet. Garasic argues that in space, genetic enhancement interventions are morally acceptable, as they are essential for survival. On Earth, however, we can survive even without any form of (bio)enhancement. In a previous article (2022), we presented several arguments against Garasic’s thesis regarding the exceptional morality of what is morally acceptable in space. In this article, we examine and reply to Garasic (2022), showing that he fails to defend his thesis from the objections we previously advanced. Garasic’s mistakes are: (1) assuming nature (and consequently what is “natural”) as a normative point of reference which allows establishing what is moral and what is not moral; (2) defending the choices concerning reproduction as an insufficiently demanding and therefore unsatisfactory moral principle (according to Garasic we should not bring into the world people who can have a quality of life or a condition of well-being superior to mere survival); and finally (3) of not explaining clearly what it means to defend a principle of moral exceptionalism for space travel (Garasic does not explain whether this position applies to any behavior, for which what on Earth is a virtue, in space is a vice or is not a general principle, but he makes this case only for enhancement and reproductive technologies). Through our analysis, we not only refute Garasic’s position but also show that any attempt to address space travel issues as “special” moral issues faces several difficulties and, ultimately, is doomed to failure.

Already in 1835 Lobachevski entertained the possibility of multiple geometries of the same type playing a role. This idea of rival geometries has reappeared from time to time but had yet to become a key idea in space-time philosophy prior to Brown's _Physical Relativity_. Such ideas are emphasized towards the end of Brown's book, which I suggest as the interpretive key. A crucial difference between Brown's constructivist approach to space-time theory and orthodox "space-time realism" pertains to modal (...) scope. Constructivism takes a broad modal scope in applying to all local classical field theories---modal cosmopolitanism, one might say, including theories with multiple geometries. By contrast the orthodox view is modally provincial in assuming that there exists a _unique_ geometry, as the familiar theories have. These theories serve as the "canon" for the orthodox view. Their historical roles also suggest a Whiggish story of inevitable progress. Physics literature after c. 1920 is relevant to orthodoxy primarily as commentary on the canon, which closed in the 1910s. The orthodox view explains the spatio-temporal behavior of matter in terms of the manifestation of the real geometry of space-time, an explanation works fairly well within the canon. The orthodox view, Whiggish history, and the canon have a symbiotic relationship. If one happens to philosophize about a theory outside the canon, space-time realism sheds little light on the spatio-temporal behavior of matter. Worse, it gives the _wrong_ answer when applied to an example arguably _within_ the canon, a sector of Special Relativity, namely, _massive_ scalar gravity with universal coupling. Which is the true geometry---the flat metric from the Poincare' symmetry group, the conformally flat metric exhibited by material rods and clocks, or both---or is the question faulty? How does space-time realism explain the fact that all matter fields see the same curved geometry, when so many ways to mix and match exist? Constructivist attention to dynamical details is vindicated; geometrical shortcuts can disappoint. The more exhaustive exploration of relativistic field theories in particle physics, especially massive theories, is a largely untapped resource for space-time philosophy. (shrink)

The experience of embodiment may be studied using the rubber hand illusion. Little is known about the cognitive mechanism that elicits the feeling of embodiment. In previous models of the rubber hand illusion, bodily signals are processed sequentially. Such models cannot explain some more recent findings. Carruthers (2013) proposed a multidimensional model of embodiment, in which the processing of embodiment is understood in terms of conceptual hand space. Visual features of hands are represented along several dimensions. The rubber hand (...) illusion is then explained as the erroneous matching of the online representation of the artificial hand to the stored prototype in a space defined by those dimensions. We conducted the first experimental tests to investigate the multidimensional conceptual space account. First, participants performed a series of odd-one-out judgments for triads of hand images (including their own hand) and we then employed multidimensional scaling analyses. We found that a multidimensional model of perceived hand similarity could be fitted to our data. Second, we tested if a multisensory bodily signal manipulation (the rubber hand illusion) influences the position of the viewed artificial hand in hand space. We employed synchronous and asynchronous stroking and found that in the synchronous condition, which elicits the rubber hand illusion, compared to the asynchronous condition, which does not, the artificial hand was closer to the center of hand space; that is, to a prototype hand. We discuss these findings in the context of the Carruthers (2013) conceptual space model as well as other rubber hand illusion models. (shrink)

This volume provides a much needed, historically accurate narrative of the development of theories of space up to the beginning of the eighteenth century. It studies conceptions of space that were implicitly or explicitly entailed by ancient, medieval and early modern representations of the cosmos. The authors reassess Alexandre Koyré’s groundbreaking work From the Closed World to the Infinite Universe and they trace the permanence of arguments to be found throughout the Middle Ages and beyond. By adopting a (...) long timescale, this book sheds new light on the continuity between various cosmological representations and their impact on the ontology and epistemology of space. Readers may explore the work of a variety of authors including Aristotle, Epicurus, Henry of Ghent, John Duns Scotus, John Wyclif, Peter Auriol, Nicholas Bonet, Francisco Suárez, Francesco Patrizi, Giordano Bruno, Libert Froidmont, Marin Mersenne, Pierre Gassendi, Gottfried Wilhelm Leibniz and Samuel Clarke. We see how reflections on space, imagination and the cosmos were the product of a plurality of philosophical traditions that found themselves confronted with, and enriched by, various scientific and theological challenges which induced multiple conceptual adaptations and innovations. This volume is a useful resource for historians of philosophy, those with an interest in the history of science, and particularly those seeking to understand the historical background of the philosophy of space.

Discutir a potencialidade imagem em movimento no ensino de Filosofia e a compreensão do filme como discurso significante, conjugando as experiências desenvolvidas em pesquisas e sala de aula. Apresentar também recortes de disciplina ministrada que utilizou textos filosóficos e episódio de StarTrek Deep Space Nine. O filme é entendido como texto fílmico, um objeto em cuja materialidade estão inscritos diferentes códigos da linguagem cinematográfica, e como documento informacional, que comporta diferentes níveis de informações que necessitam ser reconhecidas e trabalhadas, (...) a fim de que o uso pedagógico seja satisfatório. Assim, para além do entretenimento, o texto fílmico tem a possibilidade de ser usado como recurso pedagógico e de análise social. Observa-se como constitutivos do universo Trek os filmes realizados para o cinema e as séries televisivas. (shrink)

Purpose. The article suggested for consideration is aimed at clarifying the shift in human perception from the spatial turn announced by Michel Foucault, to a performative turn. The performative turn has an anthropological footing. It is based on the all-round investigation of the body’s principal role for cultural existence, as a result of a reverse reaction to artificial conceptual gap between space and body, which basically means ignoring the embodiment theme. An example of such theoretical deformation was Edmund Husserl’s (...) “anthropology phobia” revealed and thoroughly analysed by Hans Blumenberg in his critical works. Originality of the approach applied in this research, first and foremost, demonstrates not an abstract phenomenological conception as a theoretical construct, but a phenomenological activity itself, as well as practical work expressing antepredicative experience and solving the problems arising in this complicated process. Applying the Blumenberg’s analysis also allows to peep in the sideline notes of Edmund Husserl himself, which, for their part, acquire special meaning in relation to such a practical (performative) turn. Conclusions show the following state of affairs demonstrated by the anthropological and performative shift towards the body theme: 1) absolutisation of space without mentioning its relation to body experience is unreasonable and groundless, like in Husserl’s “anthropology phobia ”; 2) since the ground itself is a metaphorical anthropology basis, anthropology can reveal the structural conditions of perception due to thematic fronting of embodiment; 3) this gives anthropology some compensational features, to avoid false culture and nature dualism; 4) so, the space and body relationship is expressed by the Vehikel-phenomenon (transport phenomenon) of the body itself, by placing, arranging and depicting, and thus replacing something missing and unavailable for direct contemplation, by revealing the spatial infrastructure for object perception, creating the presence conditions and metaphorically marking the contemplation boundary; 5) the depicting arrangement (Darstellung) is at the same time a bodily performance, a play, staging and performing, which gives an aesthetic, poetic and emphatic impact on the use of philosophy language, in our case, on the way a phenomenology philosopher works with the language.

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)
