Time, Change and Freedom is the first introduction to metaphysics that uses the idea of time as a unifying principle. Time is used to relate the many issues involved in the complex study of metaphysics. Sections of the book are written in dialogue form which allows the reader to question the theories while they read and have those queries answered in the text. In addition, the authors provide glossaries of key terms as well as recommendations for further reading at the (...) conclusion of each chapter. Quentin Smith and L. Nathan Oaklander examine the tensions between determinism and freedom, temporality and historical change as well as an array of other issues fundamental to introductory metaphysics. (shrink)

This volume puts together twelve new essays by scholars who have done groundbreaking work in epistemology over the past four decades. Unfortunately, the editor’s brief introduction offers only a sketchy presentation of the papers and their background. Given the variety and complexity of the issues tackled, one would have expected a more detailed account of the nature and developments of the epistemological theories and arguments put forward and discussed by the contributors. The absence of such an account is all the (...) more surprising considering that the editor does not himself contribute a paper to the volume. (shrink)

Atheists have tacitly conceded the field to theists in the area of philosophical cosmology, specifically, in the enterprise of explaining why the universe exists. The theistic hypothesis is that the reason the universe exists lies in God’s creative choice, but atheists have not proposed any reason why the universe exists. I argue that quantum cosmology proposes such an atheistic reason, namely, that the universe exists because it has an unconditional probability of existing based on a functional law of nature. This (...) law of nature (“the wave function of the universe”) is inconsistent with theism and implies that God does not exist. I criticize the claims of Alston, Craig, Deltete and Guy, Oppy and Plantinga that theism is consistent with quantum cosmology. (shrink)

In George Nakhnikian’s interesting and stimulating paper, “Quantum Cosmology, Theistic Philosophical Cosmology, and the Existence Question” (present issue) he addresses the fundamental issue of whether it is metaphysically possible or justifiable to believe that our universe began to exist without a cause, divine or otherwise. His conclusion is negative, and he argues that, contrary to my views, quantum cosmology is consistent with theism. In this paper, I shall evaluate Nakhnikian’s arguments.

Contemporary science presents us with the remarkable theory that the universe began to exist about fifteen billion years ago with a cataclysmic explosion called "the Big Bang." The question of whether Big Bang cosmology supports theism or atheism has long been a matter of discussion among the general public and in popular science books, but has received scant attention from philosophers. This book sets out to fill this gap by means of a sustained debate between two philosophers, William Lane Craig (...) and Quentin Smith, who defend opposing positions. Craig argues that the Big Bang that began the universe was created by God, while Smith argues that the Big Bang has no cause. Alternating chapters by the two philosophers criticize and attempt to refute preceding arguments. Their arguments are based on Einstein's theory of relativity and include a discussion of the new quantum cosmology recently developed by Stephen Hawking and popularized in A Brief History of Time.

Original essays by philosophers of language and philosophers of time exploring the semantics and metaphysics of tense.

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.

The Preface and the General Introduction to the book set the debate within the wider philosophical context and show why the subject of temporal becoming is a perennial concern of science, religion, language, logic, and the philosophy of ...

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.

The main goal of Michael Tooley’s groundbreaking book is to establish a position intermediate between the tenseless theory of time and the standard tensed theory of time. Tooley argues for a novel version of the tensed theory of time, namely, that the future is unreal and the present and past real, and yet that reality consists only of tenseless facts. The question that naturally arises for the reader concerns an apparent paradox: how could the tensed theory of time be true (...) if reality consists only of tenseless facts? (shrink)

you use it. These two assumptions, which I believe to be false, are based on a more fundamental assumption, that the rule governing the reference of an indexical remains constant from use to use. Contemporary theories hold that the reference of an indexical varies from use to (relevantly different) use, but that the reference-fixing rule of use is You can search..

The primary goal of Peter Ludlow's Semantics, Tense, and Time is to illustrate how one can study metaphysical issues from a linguistic/semantic perspective by addressing the debate between tenseless theorists and tensed theorists. Ludlow's book is noteworthy in part because of the novelty of its approach to this debate and in part because it addresses and endeavors to solve the metaphysical problems of temporal solipsism that other temporal solipsists have not addressed.

This is a critical history of analytic philosophy from its inception in the late-19th century to the present day. The book focuses on the connections between the four leading movements in the field - logical realism, logical positivism, ordinary language analysis and linguistic essentialism.

The new tenseless theory of time, Developed primarily by j j c smart and d h mellor, States that tensed sentence-Utterances cannot be translated by tenseless ones but nevertheless have tenseless truth conditions. Smart and mellor infer from this that the tenseless theory of time is true. The author argues, However, That the rules of use of tensed sentence-Utterances entail that these utterances also have tensed truth conditions. This implies that the tensed theory of time is true.

There is sufficient evidence at present to justify the belief that the universe began to exist without being caused to do so. This evidence includes the Hawking-Penrose singularity theorems that are based on Einstein's General Theory of Relativity, and the recently introduced Quantum Cosmological Models of the early universe. The singularity theorems lead to an explication of the beginning of the universe that involves the notion of a Big Bang singularity, and the Quantum Cosmological Models represent the beginning largely in (...) terms of the notion of a vacuum fluctuation. Theories that represent the universe as infinitely old or as caused to begin are shown to be at odds with or at least unsupported by these and other current cosmological notions. (shrink)

It seems intuitively obvious that what I am doing right now is more real than what I did just one second ago, and it seems intuitively obvious that what I did just one second ago is more real than what I did forty years ago. And yet, remarkably, every philosopher of time today, except for the author, denies this obvious fact about reality. What went wrong? How could philosophers get so far away from what is the most experientially evident fact (...) about reality? (shrink)

In "A Cosmological Argument for a Self-Caused Universe ," one of us (Smith) argued that the universe explains its own existence because (i) its existence is entailed by (and so explained by) the existence of the infinitely many instantaneous universe states that compose it, and (ii) each of those states is caused by (and so explained by) infinitely many earlier universe states.[1] Moreover, (ii) is true even if the universe is finitely old because, given standard Big Bang cosmology (Friedmann (...) cosmology), the universe does not exist at t0 (i.e., the Big Bang singularity is not real) and no matter how close some moment tn (at which the universe does exist) is to t0, there are infinitely many (indeed continuum-many) moments at which the universe exists that are even closer. Thus, even a finitely old universe has no beginning in the sense of a first moment, and hence its state at any moment is (sufficiently) caused by (all of) the universe states that precede it. Further, since this explanation of the existence of the universe is complete despite making no reference to God, and since God by definition is a part of any complete explanation of the universe, it follows that God does not exist.

Consciousness is perhaps the most puzzling problem we humans face in trying to understand ourselves. Here, eighteen essays offer new angles on the subject. The contributors, who include many of the leading figures in philosophy of mind, discuss such central topics as intentionality, phenomenal content, and the relevance of quantum mechanics to the study of consciousness.

One of the central debates in current analytic philosophy of time is whether time consists only of relations of simultaneity, earlier and later (B-relations), or whether it also consists of properties of futurity, presentness and pastness (A-properties). If time consists only of B-relations, then all temporal determinations are permanent; if at anyone time it is the case that birth is later than Homer's birth, then it is ever after the case that Dante's birth is later than Homer's. The temporal position (...) of Dante's birth vis a vis Homer's is permanently fixed. Moreover, if B-relations are the only temporal determinations possessed by events, then each event, regardless of when it occurs, is equally as real as each other event. Each event sustains B-relations to other events, and thus in respect of its temporal determinations is ontologically undistinguished from each other event. Why should Dante's birth be "more real" than Homer's just because it is later than it? But if time also consists of A-properties, then some events are ontologically distinguished by virtue of their temporal determinations; the events that are or exist in the tensed sense, the events that possess the A-property of present- ness, have a reality not possessed by other events. All other events are no longer (are past) or are not yet (are future), and in this respect are deprived of the being, the presentness, possessed by the events that are. The A-properties possessed by events are impermanent temporal determinations; if an event possesses a certain A-property at one time, then there is another time at which the event will not have that A-property but some other A-property instead. First an event is future, then it is present, and finally it is past. This shows that the issue between the defenders of the B-theory and the defenders of the A-theory is of fundamental ontological importance. But analytic philosophers discuss this issue ,almost exclusively in terms of the language we use to describe the temporal determinations of events. They engage in what Quine calls "semantic ascent", i.e., redirecting their concern from the "things themselves" to the words we use to describe things. Defenders of the A-theory argue that tensed sentences and their tokens, sentences containing tensed copulas like "is", "was" and "will be" and adverbs like "now" and "at present", are untranslatable or unanalyzable into tenseless sentences about B- related events, and therefore that the tensed copulas and ad- verbs refer to A-properties of events. Defenders of the B-theory argue that tensed sentences or their tokens are translatable or analyzable into tenseless sentences about B-related events, and hence that the tensed sentences or tokens refer only to B-related events. While this semantic ascent is not without its advantages, it seems to me that additional light can be thrown on this subject if it is approached from a nonlinguistic phenomenological perspective. This approach is all the more needed since this particular issue in the philosophy of time has not been explicitly addressed by any of the practitioners of "phenomenology" (in the wide sense), such as Husserl, Scheler, Heidegger, Sartre and Merleau-Ponty .Indeed, phenomenologists have generally seemed to be unaware of the debate between the A-theorists and B-theorists. This issue has been a concern exclusively of analytic philosophers (with the exception perhaps of the early 20th century British Idealist John McTaggart.) In this paper, I will point to a number of phenomenological facts that are pertinent to the debate. These facts all favor the A-theory. I shall make the case that the basic phenomenological truths about time simply cannot be accounted for by the B-theory . (shrink)

In a critical dialogue with the metaphysical tradition from Plato to Hegel to contemporary schools of thought, the author convincingly argues that traditional rationalist metaphysics has failed to accomplish its goal of demonstrating the existence of a di.

The standard view of philosophers is that the existence of particular events within our universe is capable of being explained in terms of initial conditions and natural laws, but that the existence of our universe itself is a 'brute given' that is incapable of naturalistic explanation. A supernatural explanation of the existence of our universe may be alleged to be possible ('God created our universe so that humans may exist and the existence of humans is an intrinsic good'), but an (...) explanation that appeals only to factors, situations or regularities in nature is deemed to be in principle impossible. It is also a standard view of philosophers that the less fundamental natural laws of our universe are capable of being explained in terms of more fundamental laws of our universe, but that the most basic natural laws of our universe are incapable of being explained naturalistically. Perhaps they can be explained supernaturally, by asserting that God ordained them so that humans may eventually evolve, but no other explanation is supposed possible. (shrink)

A clearer case of a horrible event in nature, a natural evil, has never been presented to me. It seemed to me self evident that the natural law that animals must savagely kill and devour each other in order to survive was an evil natural law and that the obtaining of this law was sufficient evidence that God did not exist. If I held a certain epistemological theory about "basic beliefs", I might conclude from this experience that my intuition that (...) there is no God co existing with th is horror was a "basic belief" and thus that I am epistemically entitled to be an atheist without needing to justify this intuition, But I do not hold such an epistemological theory and believe that intuitive atheological beliefs, such as the one I experienced (and the corresponding intuitive theological beliefs, such as that God is providentially watching over this gruesome event) require justification if they are to be epistemically warranted. The following sections of this article present a justification for the atheological intuition I experienced that dark night. My justification will consist mostly in providing reasons to believe premise (3) in the following probabilistic argument.. (shrink)

This inquiry is motivated by the question: if atheism is true, is it nevertheless the case that holiness or sacredness is exemplified? I believe the answer to this question is affirmative, and that the path to its affirmation lies in the rejection of the traditional assumption that holiness is a single and simple property of a divinity that eludes analysis. The opposite view, that there are several complex properties comprising holiness, makes it manifest that there are holy beings, even a (...) holy ‘supreme being’, even if there is no God and no gods.

In this paper, presented at an APA colloquium in Boston on December 28, 1994, it is argued that Ruth Barcan Marcus' 1961 article on Modalities and Intensional Languages originated many of the key ideas of the New Theory of Reference that have often been attributed to Saul Kripke and others. For example, Marcus argued that names are directly referential and are not equivalent to contingent descriptions, that names are rigid designators, and that identity sentences with co-referring names are necessary if (...) true. She also first presented the modal argument that names are directly referential, the epistemic argument that names are directly referential, and the argument that there area posteriori necessities.
