Hydrological landscapes played a significant role in the elaboration of Gaston Bachelard’s and Martin Heidegger’s historical epistemologies. More specifically, both philosophers relied on hydroelectric landscapes to explore nonlinear time and profound epistemological shifts in the history of knowledge. The landscapes they invoke are composed of hydroelectric dams, thunderstorms, and related landmarks like mountains, rivers, and lakes. Together, these varied yet connected elements offer rich environmental and conceptual terrains that I revisit to situate human knowledge formation within a much older (...) natural history, and to lay the groundwork for a deep time theory of knowledge. Such theories promote timefulness and geological consciousness by establishing less anthropocentric historical narratives – or what Dipesh Chakrabarty calls “planetary history” – on more suitable epistemological grounds.

This paper addresses the significance of the general class of diffeomorphisms in the theory of general relativity as opposed to the Poincaré group in a special relativistic theory. Using Anderson's concept of an absolute object for a theory, with suitable revisions, it is shown that the general group of local diffeomorphisms is associated with the theory of general relativity as its local dynamical symmetry group, while the Poincaré group is associated with a special relativistic theory (...) as both its global dynamical symmetry group and its geometrical symmetry group. It is argued that the two groups are of equal significance as symmetry groups of their associated theories. (shrink)

Foundations of Space-Time Theories, by Michael Friedman, falls naturally into two parts. In the first, he presents the general framework within which he will characterize and discuss space-time theories, and then he devotes a chapter each to Newtonian physics, special relativity, and general relativity. Although there is some rich philosophical discussion along the way, these chapters are, of necessity, somewhat technical expositions of the general framework in action. It is in the second part, consisting of two substantial chapters, (...) one on relationalism, the other on conventionalism, that more general philosophical issues are addressed. (shrink)

"This book develops a rigorous theory of indeterminism as a local and modal concept. Its crucial insight is that our world contains events or processes with alternative, really possible outcomes. The theory aims at clarifying what this assumption involves, and it does it in two ways. First, it provides a mathematically rigorous framework for local and modal indeterminism. Second, we support that theory by spelling out the philosophically relevant consequences of this formulation and by showing its fruitful (...) applications in metaphysics. To this end, we offer a formal analysis of modal correlations and of causation, which is applicable in indeterministic and non-local contexts as well. We also propose a rigorous theory of objective single-case probabilities, intended to represent degrees of possibility. In a third step, we link our theory to current physics, investigating how local and modal indeterminism relates to issues in the foundations of physics, in particular, quantum non-locality and spatio-temporal relativity. The book also ventures into the philosophy of time, showing how the theory's resources can be used to explicate the dynamic concept of the past, present, and future based on local indeterminism"--.

This book, explores the conceptual foundations of Einstein's theory of relativity: the fascinating, yet tangled, web of philosophical, mathematical, and physical ideas that is the source of the theory's enduring philosophical interest. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The (...) goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Should you care less about your distant future? What about events in your life that have already happened? How should the passage of time affect your planning and assessment of your life? Most of us think it is irrational to ignore the future but harmless to dismiss the past. But this book argues that rationality requires temporal neutrality.

Can the Marxist tradition still provide new resources for thinking the specificity of historical time? This volume proposes to transform our understanding of Marxism by reconnecting with the 'subterranean currents' of plural temporalities that have traversed its development. From Rousseau and Sieyès to Marx, from Bloch to Althusser, from Gramsci to Pasolini and Postcolonialism, the chapters in this volume seek both to valorise neglected resources from Marxism's contradictory history, and also to read against the grain its orthodox and heterodox (...) currents. Privileging not the single time of historical development, but the plural temporalities that intertwine in and constitute any given historical conjuncture, and arguing against merely subjectivist theories of temporal multiplicity, this volume studies the articulation of the real, plural temporalities of mass political action. Comprehending their dynamics is a necessary precondition for a renewed politics of emancipation.Contributors include: Luca Basso, Stefano Bracaletti, Mauro Farnesi Camellone, Fabio Frosini, Augusto Illuminati, Nicola Marcucci, Vittorio Morfino, Luca Pinzolo, Peter D.

I present a discussion of some open issues in the philosophy of space-time theories. Emphasis is put on the ontological nature of space and time, the relation between determinism and predictability, the origin of irreversible processes in an expanding Universe, and the compatibility of relativity and quantum mechanics. In particular, I argue for a Parmenidean view of time and change, I make clear the difference between ontological determinism and predictability, propose that the origin of the asymmetry observed (...) in physical processes is related to the existence of cosmological horizons, and present a non-local concept of causality that can accommodate both special relativity and quantum entanglement.

A space-time theory is studied in a framework of four-dimensional symmetry, In this theory there is a privileged frame (ether frame), and the simultaneity of distant clocks is absolute. The results of such a theory are not only equivalent to special relativity, but also valid to describe the superluminous phenomena.

Art In Its Time takes a close look at the way in which art has become integral to the everyday 'ordinary' life of modern society. It explores the prevalent notion of art as transcending its historical moment, and argues that art cannot be separated from the everyday as it often provides material to represent social struggles and class, to explore sexuality, and to think about modern industry and our economic relationships.

In this study, we analyze choice in the presence of some conflict that affects the decision time, a subject that has been documented in the literature. We axiomatize a multiattribute decision time representation, which is a dynamic extension of the classic multiattribute expected utility theory that allows potentially incomplete preferences. Under this framework, one alternative is preferred to another in a certain period if and only if the weighted sum of the attribute-dependent expected utility induced by the (...) former alternative is larger than that induced by the latter for all attribute weights in a closed and convex set. MDT uniquely determines the decision time as the earliest period at which the ranking between alternatives becomes decisive. The comparative statics result indicates that the decision time provides useful information to locate indifference curves in a specific setting. MDT also explains various empirical findings in economics and other relevant fields. (shrink)

This is an exciting exploration of the role art plays in our lives. Mattick takes the question "What is art?" as a basis for a discussion of the nature of art, he asks what meaning art can have and to whom in the present order.

This book is about time and its powerful influence on our personal and collective daily life. It presents the most comprehensive and up-to-date overview of contemporary knowledge on temporal psychology inspired by Zimbardo's work on Time Perspective (TP). With contributions from renowned and promising researchers from all over the globe, and at the interface of social, personality, cognitive and clinical psychology, the handbook captures the breadth and depth of the field of psychological time. Time perspective, as (...) the way people construe the past, the present and the future, is conceived and presented not only as one of the most influential dimensions in our psychological life leading to self-impairing behaviors, but also as a facet of our person that can be de-biased and supportive for well-being and happiness. Written in honor of Philip G. Zimbardo on his 80th birthday and in acknowledgement of his leading role in the field, the book contains illustrations of the countless studies and applications that his theory has stimulated, and captures the theoretical, methodological and practical pathways he opened by his prolific research.

It is argued that the so-called “absolute space-time theory” is inconsistent, in disagreement with some astronomical observations, and improperly titled.

A rebuttal is given of points of criticism raised by Z. Vrcelj against S. Marinov's absolute space-time theory.

Augustine's "Confessions" in the "question time" by later philosophers and spoke highly of the attention, but the emphasis is often placed where "mind stretching" of this dimension, to the neglect of God's creation of this dimension, ignoring the eternal the dimension. In fact, God's creation and the spiritual dimensions of these two inseparable extension, the former provides the latter, to clarify the origin of time; the latter reflects the former, indicating the existence and nature of time. The (...) latter by the former constraints. In other words, there is a limit stretch the mind, is insurmountable. When Windelband stressed Augustine's metaphysics is the "inner experience, metaphysics," he confirmed the view of Augustine's spiritual dimension of time; when Gilson called the "conversion of metaphysics," when it is stressed that "stretch the boundaries of the mind "that is the eternal God's creation. "The question of time" in Augustine's Confessions was extensive concerned and highly remarked by later philosophers. However, they always just paid attention to "Extension of Mind" and ignored the Creation of God and its relationship to Eternity. In fact the two dimensions, ie, the creation of God and the extension of mind, cannot be separated. The former decides the latter, expounding the origin of time; the latter reflects the former, expressing the existence and essence of time. Generally the latter is limited by the former. In other words,, there is a boundary line between them and it can't be surmounted. When W. Windelband emphasized Augustine's metaphysics is "Metaphysics of immanent experience", what he confirmed is the psychological dimension Augustine's time theory; When E. Gilson called it "the converted metaphysics", what he emphasized is "the limit of the mind's extension", namely eternal God's creation. (shrink)

The history and philosophy of science are destined to play a fundamental role in an epoch marked by a major scientific revolution. This ongoing revolution, principally affecting mathematics and physics, entails a profound upheaval of our conception of space, space–time, and, consequently, of natural laws themselves. Briefly, this revolution can be summarized by the following two trends: by the search for a unified theory of the four fundamental forces of nature, which are known, as of now, as gravity, (...) electromagnetism, and strong and weak nuclear forces; by the search for new mathematical concepts capable of elucidating and therefore explaining such a relationship. In fact, the first search is essentially dependent on the second; that is to say, that in order for a new theory of physics to come to light, the development of a deeper geometric theory capable of explaining the structure of space–time on a quantum scale appears to be necessary. On careful consideration, we notice that both of these developments converge in the direction of a unitary and fundamental tendency of modern science—which is the geometrization of theoretical physics and of natural sciences. This new emergent situation carries within it a profound conceptual change, affecting the way in which relations are conceived of, first and foremost, between mathematics and physics. This new paradigm can be summed up by the intimately interdependent points: the immense variety of physical phenomena and of natural forms follows from the equally infinite variety of geometric and topological objects that can be made out in space and from which space is made up; the second point, which ensues from the former one and which is of great historical and epistemological significance, is that mathematics is involved in rather than applied to phenomena. In other words, phenomena are effects that emerge from the geometrical structure of space–time. There is no doubt that this new conception of the relationship between the universe of mathematical ideas and objects and the world of natural phenomena is the true scientific revolution of our century, of great conceptual importance, and consequently, capable of changing our view of science and of nature at one and the same time. It is all at once of a scientific, philosophical and aesthetic order. (shrink)

We prove that the classical theory with a discrete time (chronon) is a particular case of a more general theory in which spinning particles are associated with generalized Lagrangians containing time-derivatives of any order (a theory that has been called “Non-Newtonian Mechanics”). As a consequence, we get, for instance, a classical kinematical derivation of Hamiltonian and spin vector for the mentioned chronon theory (e.g., in Caldirola et al.’s formulation). Namely, we show that the extension (...) of classical mechanics obtained by the introduction of an elementary time-interval does actually entail the arising of an intrinsic angular momentum; so that it may constitute a possible alternative to string theory in order to account for the internal degrees of freedom of the microsystems.

Proceeding from our absolute space-time conceptions, we obtain the formula for the gravitational frequency shift in an extremely simple way. Using our “burst” model for photons, we show that the different rates of clocks placed in spatial regions with different gravitational potentials appear as a direct result of the gravitational frequency shift and the axiomatic assumption that at any space point the time unit is to be defined by light clocks with equal “arms,” i.e., that at any space (...) point the light velocity (in moving frames the “there-and-back” velocity) has the same numerical valuec. Considering the principle of equivalence, we come to the logical conclusion that the kinematic (Einstein-Lorentz) time dilation is an absolute phenomenon. (shrink)

In the light of our recently performed experiments, revealing the anisotropy of light velocity in any frame moving with respect to absolute space, we show that the Lorentz transformation, where the relativity of light velocity is given implicitly through the relativity of the time coordinates, must be treated from an absolute point of view if one seeks to preserve its adequacy to physical reality. Then we propose a new transformation (which is to be considered as a legitimate companion of (...) the Lorentz transformation) wherein the relativity of light velocity is given explicitly and the time coordinates are absolute.

“The universe is expanding, not contracting.” Many statements of this form appear unambiguously true; after all, the discovery of the universe’s expansion is one of the great triumphs of empirical science. However, the statement is time-directed: the universe expands towards what we call the future; it contracts towards the past. If we deny that time has a direction, should we also deny that the universe is really expanding? This article draws together and discusses what I call ‘C-theories’ of (...) time — in short, philosophical positions that hold time lacks a direction — from different areas of the literature. I set out the various motivations, aims, and problems for C-theories, and outline different versions of antirealism about the direction of time. (shrink)

We find the relation between the frequencies received by two observers placed at a given parallel with 180° difference in longitude when they observe a distant light (radio) source. This relation depends on the absolute velocity of the Earth; however, because of the occurrence of aberration, the effect cannot be registered in practice.

In the first part of this contribution, we review the development of the theory of scale relativity and its geometric framework constructed in terms of a fractal and nondifferentiable continuous space-time. This theory leads (i) to a generalization of possible physically relevant fractal laws, written as partial differential equation acting in the space of scales, and (ii) to a new geometric foundation of quantum mechanics and gauge field theories and their possible generalisations. In the second part, we (...) discuss some examples of application of the theory to various sciences, in particular in cases when the theoretical predictions have been validated by new or updated observational and experimental data. This includes predictions in physics and cosmology (value of the QCD coupling and of the cosmological constant), to astrophysics and gravitational structure formation (distances of extrasolar planets to their stars, of Kuiper belt objects, value of solar and solar-like star cycles), to sciences of life (log-periodic law for species punctuated evolution, human development and society evolution), to Earth sciences (log-periodic deceleration of the rate of California earthquakes and of Sichuan earthquake replicas, critical law for the arctic sea ice extent) and tentative applications to systems biology.

In this paper I consider two strategies for providing tenseless truth-conditions for tensed sentences: the token-reflexive theory and the date theory. Both theories have faced a number of objections by prominent A-theorists such as Quentin Smith and William Lane Craig. Traditionally, these two theories have been viewed as rival methods for providing truth-conditions for tensed sentences. I argue that the debate over whether the token-reflexive theory or the date theory is true has arisen from a failure (...) to distinguish between conditions for the truth of tensed tokens and conditions for the truth of propositions expressed by tensed tokens. I demonstrate that there is a true formulation of the token-reflexive theory that provides necessary and sufficient conditions for the truth of tensed tokens, and there is a true formulation of the date theory that provides necessary and sufficient conditions for the truth of propositions expressed by tensed tokens. I argue that once the views are properly formulated, the A-theorist’s objections fail to make their mark. However, I conclude by claiming that even though there is a true formulation of the token-reflexive theory and a true formulation of the date theory, the New B-theory nonetheless fails to provide a complete account of the truth and falsity of tensed sentences.
