Studies On The Structure Of Time

One of the most enigmatic aspects of experience concerns time. Since pre-Socratic times scholars have speculated about the nature of time, asking questions such as: What is time? Where does it come from? Where does it go? The central proposal of The Structure of Time is that time, at base, constitutes a phenomenologically real experience. Drawing on findings in psychology, neuroscience, and utilising the perspective of cognitive linguistics, this work argues that our experience of time may ultimately derive from perceptual processes, which in turn enable us to perceive events. As such, temporal experience is a pre-requisite for abilities such as event perception and comparison, rather than an abstraction based on such phenomena. The book represents an examination of the nature of temporal cognition, with two foci: (i) an investigation into (pre-conceptual) temporal experience, and (ii) an analysis of temporal structure at the conceptual level (which derives from temporal experience).

Every human being is aware of the flow of time. This fact is embodied in the existence of such notions as the past and the future, the two domains being separated from each other by the single moment of the present. While the past is regarded as fixed and definite, the future is viewed as unknown, uncertain, and undetermined. The only perceivable moment is the present, the `now' - the ever-changing point moving from the past into the future. Physics tells us a different story: not only are the vast majority of physical laws time-reversible, but the concept of the `now' itself has no place at all in physics. In other words, the equations of physics do not distinguish between the past and the future and seem to be completely oblivious to the very idea of the present. This book discusses the biological and psychological aspects of perception of time, and the problems related to the determination of location arising from quantum physics, together with comments and opinions from philosophers and physicists.

The First Conference of the International Society for the Study of Time was held at the Mathematisches Forschungsinstitut at Oberwolfach in the Black Forest, Federal Republic of Germany from Sunday, 31 August to Saturday, 6 September, 1969. The origin of this conference and the formation of the Society goes back to a proposal due to J. T. Fraser that was discussed at a conference on "Interdisciplinary Perspectives of Time" held by the New York Academy of Sciences in January, 1966. It was unanimously agreed than that an international society should be formed on an interdisciplinary basis with the object of stimulating interest in all problems concerning 'time and that this object could best be attained by means of conferences held at regular intervals. J. T. Fraser was elected Secretary, S. Watanabe Treasurer, and I was elected President. It was agreed, at my suggestion, that the organization of the first conference of the newly formed Society be left to a committee of these three officers, on the understanding that they would invite authorities on the role of time in the various special sciences and humanities to form an Advisory Board to assist them. One of the main difficulties in seeking support for an interdisciplinary conference is that most foundations confine their interest exclusively either to the sciences or to the humanities.

This book explores the role of time in rational agency and practical reasoning. Agents are finite and often operate under severe time constraints. Action takes time and unfolds in time. While time is an ineliminable constituent of our experience of agency, it is both a theoretical and a practical problem to explain whether and how time shapes rational agency and practical thought. The essays in this book are divided into three parts. Part I is devoted to the temporal structure of action and agency, from metaphysical and metaethical perspectives. Part II features essays about the temporal structure of rational deliberation, from the perspective of action theory and theories of practical reasoning. Part III includes essays about the temporal aspects of failures of rationality. Taken together, the essays in this book shed new light on our understanding of the temporality of agency that coheres with our subjective sense of finitude and explains rational agency both in time and over time. Time in Action will be of interest to advanced students and researchers working on the philosophy of time, metaphysics of action, action theory, practical reasoning, ethical theory, moral psychology, and rational justification.

Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein's field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

Essays discuss chronicles, clarify ideas of creation temporally understood, the meaning of “simultaneous times,” or simultaneity, and the concept of “no-time.” Essays also examine time in social and political contexts, as measured by clocks, as notated in music, as embodied in memorializing stone, and as the subject and medium of consciousness.
