A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

Why is the future so different from the past? Why does the past affect the future and not the other way round? The universe began with the Big Bang - will it end with a `Big Crunch'? Now in paperback, this book presents an innovative and controversial view of time and contemporary physics. Price urges physicists, philosophers, and anyone who has ever pondered the paradoxes of time to look at the world from a fresh perspective, and throws fascinating new light (...) on some of the great mysteries of the universe.

It has been repeatedly argued, most recently by Nicholas Maxwell, that the special theory of relativity is incompatible with the view that the future is in some degree undetermined; and Maxwell contends that this is a reason to reject that theory. In the present paper, an analysis is offered of the notion of indeterminateness (or "becoming") that is uniquely appropriate to the special theory of relativity, in the light of a set of natural conditions upon such a notion; and reasons (...) are given for regarding this conception as (not just formally consistent with relativity theory, but also) philosophically reasonable. The bearings upon Maxwell's program for quantum theory are briefly considered. (shrink)

_Time_'s 'Man of the Century', Albert Einstein is the unquestioned founder of modern physics. His theory of relativity is the most important scientific idea of the modern era. In this short book Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory which has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge.

Quentin Smith offers powerful arguments against the New Theory of Reference propounded by leading thhinkers in the philosophy of language. Smith defends the tensed theory of time and argues that the simultaneity is absoltue, basing this position on the theory that all propositions exist in time. Using detailed propostitions and a theory of cognitive significance, he introduces an alternative interpretation of reference that will be relevant to metaphysicians, philosophers of science and philosophers of language and may come to be recognised (...) as the definitive statement on the tensed theory of time.

This book offers a defense of the tensed theory of time, a critique of the New Theory of Reference, and an argument that simultaneity is absolute. Although Smith rejects ordinary language philosophy, he shows how it is possible to argue from the nature of language to the nature of reality. Specifically, he argues that semantic properties of tensed sentences are best explained by the hypothesis that they ascribe to events temporal properties of futurity, presentness, or pastness and do not merely (...) ascribe relations of earlier than or simultaneity. He criticizes the New Theory of Reference, which holds that "now" refers directly to a time and does not ascribe the property of presentness. Smith does not adopt the old or Fregean theory of reference but develops a third alternative, based on his detailed theory of de re and de dicto propositions and a theory of cognitive significance. He concludes the book with a lengthy critique of Einstein's theory of time. Smith offers a positive argument for absolute simultaneity based on his theory that all propositions exist in time. He shows how Einstein's relativist temporal concepts are reducible to a conjunction of absolutist temporal concepts and relativist nontemporal concepts of the observable behavior of light rays, rigid bodies, and the like.

This is a book about the philosophy of time, and in particular the philosophy of the great logician Kurt Godel (1906-1978). It evaluates Godel's attempt to show that Einstein has not so much explained time as explained it away. Unlike recent more technical studies, it focuses on the reality of time. The book explores Godel's conception of time, existence, and truth with special reference to Plato, Aristotle, Kant, and Frege. In the light of this investigation an attempt is made to (...) shed light on such issues as the precise sense in which Godel believed in the possibility of time travel, the relationship of the reality of time to the objectivity of temporal becoming, and the significance of time for human existence.This is a book about the philosophy of time, and in particular the philosophy of the great logician Kurt Godel (1906-1978).

A proof is given that there does not exist an event, that is not already in the past for some possible distant observer at the (our) moment that the latter is "now" for us. Such event is as "legally" past for that distant observer as is the moment five minutes ago on the sun for us (irrespective of the circumstance that the light of the sun cannot reach us in a period of five minutes). Only an extreme positivism: "that which (...) cannot yet be observed does not yet exist", can possibly withstand the conclusion concerned. Therefore, there is determinism, also in micro-physics.

The open future view is the common-sense view that there is an ontological difference between the past, the present, and the future in the sense that the past and the present are real, whereas the future is not yet a part of reality. In this paper we develop a theory in which the open future view is consistently combined with special relativity. Technically, the heart of our contribution is a logical conservativity result showing that, although the open future view is (...) not definable inside the causal geometry of Minkowski space-time, it can be conservatively added to it.

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

Tenseless theories of time entail that earlierthan, later than and simultaneous with (i.e.,McTaggart's `B-series') are the only temporalproperties exemplified by events. Such theories oftencome under attack for being unable to satisfactorilyaccount for tensed language. In this essay I arguethat tenseless theories of time are capable of twofeats that critics, such as Quentin Smith, argue arebeyond their grasp: (1) They can coherently explainthe impossibility of translating all tensed sentencesby tenseless counterparts; (2) They can account forcertain obviously valid entailment relations betweentensed sentence (...) types. In analyzing tensed entailmentrelations tenselessly, I favor a date analysis oftensed language over a token-reflexive theory. Theupshot is that tenseless theories of time are notundermined by the linguistic facts. (shrink)

In this paper I expound an argument which seems to establish that probabilism and special relativity are incompatible. I examine the argument critically, and consider its implications for interpretative problems of quantum theory, and for theoretical physics as a whole.

Relativity is the most important scientific idea of the twentieth century. Albert Einstein is the unquestioned founder of modern physics. His Special and General theories of Relativity introduced the idea to the world. In this classic short book he explains clearly, using the minimum amount of mathematical terms, the basic ideas and principles of his theory of Relativity. Unsurpassed by any subsequent books on Relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge.

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

Storrs McCall presents an original philosophical theory of the nature of the universe based on a striking new model of its space- time structure. He shows how his model illuminates a broad range of subjects, including causation, probability, quantum mechanics, identity, and free will, and argues that the fact that the model throws light on such a large number of problems constitutes strong evidence that the universe is as the model portrays it.

Michael Tooley presents a major new philosophical theory of the nature of time, offering a powerful alternative to the traditional "tensed" and recent "tenseless" accounts of time. He argues for a dynamic conception of the universe, in which past, present, and future are not merely subjective features of experience. He claims that the past and the present are real, while the future is not. Tooley's approach accounts for time in terms of causation. He therefore claims that the key to understanding (...) the dynamic nature of the universe is to understand the nature of causation. Time, Tense, and Causation is a landmark treatment of one of the oldest and most perplexing intellectual problems, and will be fascinating reading for anyone interested in the character of time.

Different beliefs concerning the metaphysical status of tense divide philosophers into two camps. Those who embrace a tensed theory of time argue that past, present and future correspond to genuine ontological distinctions. Those who deny the reality of such distinctions espouse a tenseless theory of time . In this essay I defend a tenseless account. ;I begin with an examination of the most prominent ontological conceptions of tense, finding them to be incoherent at worst, highly implausible at best. I then (...) turn my attention to Einstein's Special Theory of Relativity, arguing that, properly understood, it demonstrates that tenses could not be physically realized. The upshot is that tense is not a philosophically viable notion. If time is real, it must be tenseless. ;Therefore, the choice is between tenseless time and some sort of temporal idealism. Defending the former alternative, I focus my efforts, in the second part of the essay, on responding to the most important objections to a tense-free ontology. I argue that tenseless time: can explain the semantics of tensed sentences; does not entail fatalism or determinism of any kind; and is consistent with our mental experience. These results indicate that tense is a feature of perception, not a property of time itself. ;In the third part of the essay I argue that theories that constrain truth epistemically are poorly motivated and implausible. Therefore, in considering the status of tense, ontological considerations can rightly take precedence over epistemic concerns. This defuses objections to tenseless time that are based on the obvious fact that the past, present and future differ with respect to their epistemic accessibility. It is, therefore, consistent to hold that time is epistemically asymmetric but ontologically symmetric. (shrink)
