Is the objective passage of time compatible with relativistic physics? There are two easy routes to an affirmative answer: (1) provide a deflationary analysis of passage compatible with the block universe, or (2) argue that a privileged global present is compatible with relativity. (1) does not take passage seriously. (2) does not take relativity seriously. This paper is concerned with the viability of views that seek to take both passage and relativity seriously. The investigation proceeds by considering how traditional A-theoretic (...) conceptions of passage might be generalized to relativistic space-times without incorporating a privileged global present. I argue that the most promising position marries the idea that open possibilities for the future are settled as time passes with a ‘non-standard’ interpretation of the relevant formal models.

The debate between A-theory and B-theory in the philosophy of time is a persistent one. It is not always clear, however, what the terms of this debate are. A-theorists are often lumped with a miscellaneous collection of heterodox doctrines: the view that only the present exists, that time flows relentlessly, or that presentness is a property (Williams 1996); that time passes, tense is unanalysable, or that earlier than and later than are defined in terms of pastness, presentness, and futurity (Bigelow (...) 1991); or that events or facts (as opposed to language) are “tensed” (Mellor 1993). B-theorists then argue that the A-theory is incoherent, using variants on J.M.E. McTaggart’s argument for the unreality of time (McTaggart 1927, ch. 33). (shrink)

This text is a translation of an article by British idealist J.E. McTaggart “The Unreality of Time” published in the journal Mind in 1908. Author argues for the unreality of time by employing his typical methods – rejection of reality of contradictory objects, difference between real and existent, etc. This paper became a standard of excellence of McTaggart analytical style and is a classic example of British absolute idealism. The translation was made by Andrey A. Veretennikov.

It is often claimed that relativity theory falls short of giving an account of 'the flow of time' and 'the arrow of time'. Some claim that hence either one or both of these concepts do not correspond to objective reality, others infer that relativity theory is wrongfully 'spatialising' time. I investigate of our normal conception of time is enduring in relativity, even in the absence of a clear representation of flow. It is shown that the conformal structure of spacetime allows (...) for a clear distinction between past, present and future, and that the class of temporally orientable spacetimes allows for an 'arrow of time'. Finally, I briefly discuss the class of Friedmann universes, to which our universe seems to belong, and which is indeed temporally orientable. German Es wird häufig behauptet, dass die Relativitätstheorie keine adäquate Beschreibung des , Zeitflusses' und des , Zeitpfeils' enthalte. Einige ziehen daraus die Schlussfolgerung, dass beiden Konzepten nichts in der objektiven Realität entspreche, andere ziehen den Schluss, dass die Relativitätstheorie die Zeit fälschlicherweise , verräumliche'. Ich untersuche, wie viel von unserer althergebrachten Zeitvorstellung in der Relativitätstheorie überdauert, selbst in der Abwesenheit einer klaren Repräsentation von , Zeitfluss'. Ich zeige, dass die konforme Struktur der Raumzeit eine klare Unterscheidung von Vergangenheit, Gegenwart und Zukunft erlaubt, und dass die Klasse der zeitlich orientierbaren Raumzeiten die Repräsentation einer , Zeitpfeils' durchaus erlaubt. Schließlich diskutiere ich kurz die Klasse der Friedmann Raumzeiten, zu welcher unser Universum zu gehören scheint, und welches tatsächlich zeitlich orientierbar ist. (shrink)

A Brief History of the Philosophy of Time is a concise and accessible survey of the history of philosophical and scientific developments in understanding time and our experience of time. It discusses prominent ideas about the nature of time, plus many subsidiary puzzles about time, from the classical period through the present.
