Aspects of Time

Time is a complex category not only in philosophy but also in mathematics and physics. In one thought about time, the author accidentally discovered a new way to explain and solve problems related to time dilation, such as solving the problem of Muon particle when moving from a height of 10 km to the earth’s surface, while the Muon’s lifespan is only 2.2 microseconds, or explaining Michelson-Morley experiment using the new method. In addition, the author also prove that the speed (...) of light in vacuum is the maximum speed in the universe, and discovered the red shift effect while there is no increase in distance between objects. To do this, the author has built two axioms based on the discontinuity in the motion of the object and draw two consequences along with the law of conservation of time. (shrink)

Beniński filozof Paulin J. Hountondji jest autorem teorii systemu, która aspiruje do przynajmniej częściowego wytłumaczenia przyczyn złej kondycji afrykańskich społeczeństw i państw. Afrykański społeczno-polityczny stan rzeczy charakteryzuje, zdaniem Hountondjiego, przede wszystkim wadliwa organizacja struktur instytucjonalnych państw oraz codziennego życia Afrykanów. Hountondji krytykuje liczne wady afrykańskiej rzeczywistości - w tym inercję instytucji, działania pełne absurdów, marnowanie czasu, energii i zdrowia - i zarazem poszukuje ich ukrytych, „systemowych” podstaw. W rozumieniu Hountondjiego, system to zbiór wzajemnie ze sobą powiązanych elementów organizacji afrykańskich społeczeństw. (...) Istniejący system jest kontrproduktywny dla rozwoju. Myśl Hountondjiego wydaje się być adresowana przede wszystkim do samych Afrykanów, których filozof zapewne chciałby zachęcić do przemyśleń nad tym, dlaczego nie dążą oni wystarczająco skutecznie do zmiany rzeczywistości, w której żyją. Hountondji dostrzega u Afrykanów brak „woli racjonalnej organizacji, woli wykorzystania niewielu dostępnych zasobów w najlepszy możliwy sposób i dla największego możliwego zadowolenia każdego”. Zarazem wskazuje podstawowe i niezbędne, w jego opinii, działania, które mogą prowadzić do zmiany systemu, który kreuje i utrwala afrykański stan rzeczy. (shrink)

Метафизика в лице таких выдающихся мыслителей, как Хайдеггер и Гегель, вплотную подошла к проблеме введения времени в фундаментальное описание бытия. Однако указанная проблема так и не была сформулирована в рамках метафизики. Главная причина этого заключается, на наш взгляд, в том, что сама направленность метафизики на постижение вечных принципов подразумевает неизменность последних, их автономию от времени. Основой для такого воззрения выступает максима: «Что вечно, то неизменно, а что изменчиво, то не вечно». Выше мы попытались показать, что эта максима, по меньшей мере, (...) не обоснована. Но самое главное – верность подобным максимам не дает метафизике найти выход из длительного процесса ее собственного кризиса, наладить конструктивный диалог с представителями не только естественных, но и социогуманитарных (история, социология и т.д.) наук. Едва ли ее авторитету будет способствовать дисциплинарный изоляционизм. (shrink)

Susanne Langer’s idea of the primary apparition of music involves a dichotomy between two kinds of temporality: “felt time” and “clock time.” For Langer, musical time is exclusively felt time, and in this sense, music is “time made audible.” However, Langer also postulates what we would call ‘a strong suspension thesis’: the swallowing up of clock time in the illusion of felt time. In this paper we take issue with the ‘strong suspension thesis’ and its implications and ramifications regarding not (...) only musical meaning, but also the purported metaphysics of music construed as essentially inhering in felt time. We argue that this thesis is overstated and misdirecting insofar as it purports to describe what we experience when we hear music with understanding. We discuss a selection of examples of repetitive formations, from mediaeval music to contemporary music, which show that persistent, motion-inhibiting repetition undermines the listener’s ability to identify order and coherence due to a relative inability to anticipate the next occurrence of a differentiating musical event. We argue that Langer’s one-sided view of musical temporality, which patently relies on the conceptual framework of memory time and the specious present, exemplifies what we propose to call ‘the searchlight model of musical understanding,’ wherein the constant span of illumination of the searchlight (representing the span of the specious present) moves continuously parallel to, and along, its postulated target, i.e., the music heard, as it ‘illuminates’ it. We argue that, in the last analysis, memory time conceptually presupposes the publicly identifiable means of chronometric length. One maintains the ‘strong suspension thesis’ on pain of conceptual confusion. (shrink)

In the literature on the compatibility between the time of our experience and the time of physics, the special theory of relativity has enjoyed central stage. By bringing into the discussion the general theory of relativity, I suggest a new analysis of the misunderstood notion of becoming, developed from hints in Gödel's published and unpublished arguments for the ideality of time. I claim that recent endorsements of such arguments, based on Gödel's own ‘rotating’ solution to Einstein's field equation, fail: once (...) understood in the right way, becoming can be shown to be both mind-independent and compatible with spacetime physics. Being a needed tertium quid between views of time traditionally regarded as in conflict, such a new approach to becoming should also help to dissolve a crucial aspect of the century-old debate between the so-called A and B theories of time.

This paper extends the work of a previous paper on the flow of time, to consider the origin of the arrow of time. It proposes that a ‘past condition’ cascades down from cosmological to micro scales, being realized in many microstructures and setting the arrow of time at the quantum level by top-down causation. This physics arrow of time then propagates up, through underlying emergence of higher level structures, to geology, astronomy, engineering, and biology. The appropriate spacetime picture to view (...) all this is an Evolving Block Universe ‘EBU’, that recognizes the way the present is different from both the past and the future. This essential difference is the ultimate reason the arrow of time has to be the way it is. (shrink)

The author reflects on the moral attitudes displayed by Poles fighting in the Warsaw Uprising. He believes that the sacrifice and selflessness with which Varsovians battled for their city had its roots in the general mentality of the Poles, who for generations had been raised in the spirit of “mutual and willing endowment”. He also notes that the noble ideals of the wartime generations have today been largely replaced by mercenary selfishness.

I will show how a metaphysical problem of Arthur Prior’s can be solved by a logical tool he developed himself, but did not put to any foundational use: metric logic. The broader context is given by the key question about the metaphysics of time: Is time tenseless, i.e., is time just a structure of instants; or is time tensed, because some facts are irreducibly tensed? I take sides with Prior and the tensed theory. Like him, I therefore I have to (...) deal with a more specific metaphysical question: How can the instants of tenseless time be reduced to tensed facts? This is the point where, on the technical level, hybrid logic and metric logic come in. For present purposes, both can be seen as species of tense logic; and both are creations of Prior. In his argument for the tensed theory of time, Prior used hybrid tense logic to reduce instants. But, as he himself pointed out, this reduction runs into deep problems, because it immediately generalizes to other categories, for example and most importantly to persons. My main aim is to show that metric logic does not run into similar difficulties: It will help the tensed theory reduce instants, but it leaves persons untouched. I will also give reasons for preferring a metric to a hybrid logic of time that are independent of the metaphysical issue of reduction, but concern temporal reasoning, natural language semantics, and the epistemic side of time-keeping.

This paper aims to clarify the connection between the logic of temporal distinctions and the temporal features of propositions. Contra Prior, it argues that the adoption of tense operators does not commit one to the view that propositions can change their truth value over time.

Arthur N. Prior, in the Preface of Past, Present and Future, made clear his indebtedness to “the very lively tense-logicians of California for many discussions”. Strangely,with a notable exception of Copeland, there is no extensive discussion of these scholars in the literature on the history of tense logic. In this paper, I propose to study how Nino B. Cocchiarella, as one of the Californian tense-logicians, interacted with Prior in the late 1960s. By gathering clues from their correspondence available at Virtual (...) Lab for Prior Studies, I will highlight some of the differences between their views on tense-logic, which might still have far-reaching philosophical implications. I will conclude with a sketchof how to study in what ways Prior and Cocchiarella influenced some other Californian tense-logicians. (shrink)

A-theorists think there is a fundamental difference between the present and other times. This concern shows up in what kinds of properties they take to be instantiated, what objects they think exist and how they formalize their views. Nearly every contemporary A-theorist assumes that her metaphysics requires a tense logic – a logic with operators like and. In this paper, I show that there is at least one viable A-theory that does not require a logic with tense operators. And I (...) will argue that three common indispensability arguments for tense operators are unsound. (shrink)

A review of Huw Price's Time's Arrow and Archimedes' Point.

This article considers the childrens writer Alison Uttley, and, particularly, her engagements with debates regarding science and philosophy. Uttley is a well-known childrens author, most famous for writing the Little Grey Rabbit series, but very little critical attention has been paid to her. She is also an important alumna of the University of Manchester, the second woman to graduate in Physics. In particular, the article looks at her novel A Traveller in Time through the lens of her thinking on time, (...) ethics, history and science. The article draws on manuscripts in the collection of the John Rylands Library to argue that Uttley‘s version of history and time-travel was deeply indebted to her scientific education and her friendship with the Australian philosopher Samuel Alexander.

These nine essays address fundamental questions about time in philosophy, physics, linguistics, and psychology. Are there facts about the future? Could we affect the past? In physics, general relativity and quantum theory give contradictory treatments of time. So in the current search for a theory of quantum gravity, which should give way: general relativity or quantum theory? In linguistics and psychology, how does our language represent time, and how do our minds keep track of it?

If Jones buttered the toast at midnight, there is, according to Davidson, an event of Jones’ buttering of the toast. But what kind of temporal phenomenon is being referred to if Jones is in the midst of buttering the toast? By taking a Davidsonian events-based semantics as its starting point, this thesis seeks an answer to the question of “What account of temporal ontology is needed in order to explain the semantic features of the progressive aspect in English?”. In order (...) to answer the foregoing question, this thesis critically evaluates several contemporary accounts of the ontology of process, or, equivalently, the temporal ontology associated with the English progressive. These ontological accounts of process—namely those advocated by several notable neo-Davidsonians, as well as accounts by authors such as Taylor, Steward, Crowther, and Hornsby—will all be found to be wanting. By developing some remarks entered by Dummett concerning a famous passage by Frege on the notion of countability, this thesis ends by suggesting how it is that the comparatively austere temporal ontology associated with traditional Davidsonian semantics provides us with a plausible temporal ontology of the English progressive.

In this paper I am concerned with analyzing in detail how ideas and expectations regarding the role of time in quantum theory arose and evolved in the early years of quantum mechanics. The general theme is that expectations which seemed reasonable from the point of view of matrix mechanics and Dirac's q-number formalism became implausible in light of Dirac-Jordan transformation theory, and were dashed by von Neumann's Hilbert space formalism which came to replace it. Nonetheless, I will identify two concerns (...) that remain relevant today, and which blunt the force of Hilgevoord's claim that the demand that time feature as an observable arose as the result of a simple conceptual error.
