This book provides an account of the nature of time, especially time's arrow and the role of entropy, at a semi-popular level. Special attention is given to statistical mechanics, the past hypothesis, and possible cosmological explanations thereof.

Beauty is put to sleep and woken up either once or twice, depending on the flip of a coin; after each waking, she will fall asleep and forget having woken. Upon waking, what should be her credence that the coin came up heads? Some say 1/2; others say 1/3. I propose that evidence supports a theory for you when your having that qualitative evidence would be more likely if the theory were true than if it were false. This view supports (...) the “1/3” answer to the Sleeping Beauty problem. It also has applications to other arguments concerning self-locating beliefs: the Doomsday Argument fails, and the Fine Tuning Argument supports the Multiverse theory, if and only if it would be metaphysically possible for you to exist in a different universe.

In a style that is both philosophically sophisticated and accessible to general readers, Robert Almeder introduces readers to the vigorous debate in the scientific community about the possibility of personal survival after death. He argues that belief in some form of personal survival is as empirically justifiable as our belief in the past existence of dinosaurs. Drawing on 21 of the best case studies in reincarnation, apparitions of the dead, ostensible possession, out-of-body experiences, and trance mediumships, Death and Personal Survival (...) offers a comprehensive discussion of the best empirical evidence in each of these areas and refutes alternative explanations offered by sceptics.

Approaching Infinity addresses seventeen paradoxes of the infinite, most of which have no generally accepted solutions. The book addresses these paradoxes using a new theory of infinity, which entails that an infinite series is uncompletable when it requires something to possess an infinite intensive magnitude. Along the way, the author addresses the nature of numbers, sets, geometric points, and related matters. The book addresses the need for a theory of infinity, and reviews both old and new theories of infinity. It (...) discussing the purposes of studying infinity and the troubles with traditional approaches to the problem, and concludes by offering a solution to some existing paradoxes. (shrink)

Paradox Lost covers ten of philosophy’s most fascinating paradoxes, in which seemingly compelling reasoning leads to absurd conclusions. The following paradoxes are included: The Liar Paradox, in which a sentence says of itself that it is false. Is the sentence true or false? The Sorites Paradox, in which we imagine removing grains of sand one at a time from a heap of sand. Is there a particular grain whose removal converts the heap to a non-heap? The Puzzle of the Self-Torturer, (...) in which a series of seemingly rational choices has us accepting a life of excruciating pain, in exchange for millions of dollars. Newcomb’s Problem, in which we seemingly maximize our expected profit by taking an unknown sum of money, rather than taking the same sum plus $1000. The Surprise Quiz Paradox, in which a professor finds that it is impossible to give a surprise quiz on any particular day of the week... but also that if this is so, then a surprise quiz can be given on any day. The Two Envelope Paradox, in which we are asked to choose between two indistinguishable envelopes, and it is seemingly shown that each envelope is preferable to the other. The Ravens Paradox, in which observing a purple shoe provides evidence that all ravens are black. The Shooting Room Paradox, in which a deadly game kills 90% of all who play, yet each individual’s survival turns on the flip of a fair coin. Each paradox is clearly described, common mistakes are explored, and a clear, logical solution offered. Paradox Lost will appeal to professional philosophers, students of philosophy, and all who love intellectual puzzles. (shrink)

Friedrich Nietzsche’s theory of eternal recurrence is an essential part of his mature philosophy, but the theory’s metaphysical commitments and practical implications are both obscure. In this essay I consider only the metaphysical elements of the theory, with the aim of determining whether it is possible that we live our lives infinitely many times, as the theory maintains. I argue that the possibility of eternal recurrence turns on issues in personal identity and the metaphysics of time. As I proceed, I (...) also consider the relation between Nietzsche’s theory of eternal recurrence and theories of recurrence found in the work of Heraclitus, the Pythagoreans, and the Stoics.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

Two main claims are defended in this paper: first, that typical disputes in the literature about the ontology of physical objects are merely verbal; second, that the proper way to resolve these disputes is by appealing to common sense or ordinary language. A verbal dispute is characterized not in terms of private idiolects, but in terms of different linguistic communities representing different positions. If we imagine a community that makes Chisholm's mereological essentialist assertions, and another community that makes Lewis's four-dimensionalist (...) assertions, the members of each community speak the truth in their respective languages. This follows from an application of the principle of interpretive charity to the two communities. (shrink)

Several prominent philosophers, including A.J. Ayer and Derek Parfit, have offered the evidentiary requirements for believing human personality can reincarnate, and hence that Cartesian dualism is true. At least one philosopher, Robert Almeder, has argued that there are actual cases which satisfy these requirements. I argue in this paper that even if we grant the empirical data-a large concession-belief in reincarnation is still unjustified. The problem is that without a theoretical account of the alleged cases of reincarnation, the empirical evidence (...) alone does not license giving up materialist theories of the mind. (shrink)

This chapter contains sections titled: * Arguments for Divine Timelessness * Arguments for Divine Temporality * Eternity and the Nature of Time * Notes.

This book is an attempt to get to the bottom of an acute and perennial tension between our best scientific pictures of the fundamental physical structure of the ...

For much of his adult life, Nietzsche wrote notes on philosophical subjects in small notebooks that he carried around with him. After his breakdown and subsequent death, his sister supervised the publication of some of these notes under the title The Will to Power, and that collection, which is textually inaccurate and substantively misleading, has dominated the English-speaking discussion of Nietzsche's later thought. The present volume offers, for the first time, accurate translations of a selection of writings from Nietzsche's late (...) notebooks, dating from his last productive years between 1885 and 1889. Many of them have never before been published in English. They are translated by Kate Sturge from reliable texts in the Colli-Montinari edition, and they are edited by Rüdiger Bittner, whose introduction places them in the context of Nietzsche's philosophy as a whole.

I discuss classical and quantum recurrence theorems in a unified manner, treating both as generalisations of the fact that a system with a finite state space only has so many places to go. Along the way I prove versions of the recurrence theorem applicable to dynamics on linear and metric spaces, and make some comments about applications of the classical recurrence theorem in the foundations of statistical mechanics.
