n this book, Fred Seddon critically examines the views of Ayn Rand and some of her fellow Objectivists on several of the major figures in the history of philosophy, viz., Plato, Augustine, Hume, Kant and Nietzsche. There is also a chapter dealing with Rand's aesthetics, as well as three appendixes, two on Plato and one detailing the philosophy of Ayn Rand.

The purpose of this dissertation is to provide a defence of Aristotle's principle of contradiction against the critique made on it by Jan Lukasiewicz in an article he wrote in 1910 which was translated and published in the March 1971 number of The Review of Metaphysics. Lukasiewicz maintains in general that the law of contradiction has no logical worth. Specifically, he charges Aristotle with having several laws of contradiction instead of one as Aristotle claims; with attempting to prove the law (...) despite his claim that this is impossible and finally with failing in the very attempt to prove the law, or at least one of its formulations. In 20 chapters, each dealing with a respective section of Lukasiewicz's article, I attempt to show that all of Lukasiewicz's allegations are unfounded. My methodology is simply to follow Lukasiewicz through his 20 sections and compare what he says with what Aristotle actually wrote. If successful, this dissertation will show, in basic agreement with Professor Joseph Owens, that the best way to read Aristotle is on his own terms and not, as in the case of Lukasiewicz, via the latest developments in symbolic logic. I reiterate, with Aristotle, that the law of contradiction is the basic principle of being qua being and has logical worth precisely because of that fact. (shrink)

The Fate of Reason is the first general history devoted to the period between Kant and Fichte, one of the most revolutionary and fertile in modern philosophy. The philosophers of this time broke with the two central tenets of the modem Cartesian tradition: the authority of reason and the primacy of epistemology. They also witnessed the decline of the Aufkldrung, the completion of Kant's philosophy, and the beginnings of post-Kantian idealism. Thanks to Beiser we can newly appreciate the influence of (...) Kant's critics on the development of his philosophy. Beiser brings the controversies, and the personalities who engaged in them, to life and tells a story that has uncanny parallels with the debates of the present. (shrink)

This is the first book in English to elucidate the central issues in the work of Johann Gottlieb Fichte, a figure crucial to the movement of philosophy from Kant to German idealism. The book explains Fichte's notion of subjectivity and how his particular view developed out of Kant's accounts of theoretical and practical reason. Fichte argued that the subject has a self-positing structure which distinguishes it from a thing or an object. Thus, the subject must be understood as an activity (...) rather than a thing and is self-constituting in a way that an object is not. In the final chapter, Professor Neuhouser considers how this doctrine of the self-positing subject enables us to understand the possibility of the self's autonomy, or self-determination. (shrink)

This book is an account of the philosophical movement named Lebensphilosophie, which flourished at the end of the 19th and the beginning of the 20th century. There many philosophers who participated in the movement, but this book concentrates on the three most important: Friedrich Nietzsche, Wilhelm Dilthey and Georg Simmel. The movement was called Lebensphilosophie—literally, philosophy of life—because its main interest was not life as a biological phenomenon but life as it is lived by human beings. They regarded human life (...) and experience as the fundamental reality, the basis of all knowledge and value, and disputed the relevance of any supernatural realm transcending human experience. The purpose of life was therefore life itself. Lebensphilosophie was the first modern philosophical movement in the Western tradition. It was “modern” in the sense that it was entirely humanist and secular, deriving all values from a non-religious perspective. Nietzsche, Dilthey and Simmel were either atheists or agnostics; they denied the relevance of any transcendent reality or being for human life. They abjured the traditional Christian concern with salvation and immortality. They also disputed the existence of natural law, teleology or a providential order; human beings created their own values and they did not conform to any made by nature. In anticipation of later existentialism, the Lebensphilosophen maintained that human beings are the makers of their own fate. Contrary to pessimism, they affirmed the great value of life while still acknowledging its frequent tragedy. The Lebensphilosophen were champions of an individualist ethics, which maintained that the highest good for a human being was self-realization, the development of a persons’s unique individuality. Their ethics was neither utilitarian nor de-ontological: it was not utilitarian because it did not regard the highest good as pleasure; self-realization could be a very unpleasant experience; and it was not de-ontological because it grounded moral norms upon the facts of human development and experience. The Lebensphilosophen were major advocates of historicism. They believed that human experience is formed by history, and that its horizons and limits are historical. Just as it was impossible to transcend human experience, so it was impossible to transcend history. All values and norms were therefore historical. In attempting to describe historical experience, the Lebensphilosophen developed the discipline of hermeneutics. They refused to accept mechanical explanation as a paradigm of explanation. This book attempts to describe and analyze the fundamental aspects of Lebensphilosophie by looking in detail at the views of its three leading figures. It examines their ethics, their religious background, their responses to pessimism and relativism, and their contributions to hermeneutics and historicism. (shrink)

This chapter contains sections titled: Cognition as Information Processing, as Computation, and as Abiding in the Meaningful Operationalism Is This Merely a Terminological Issue? Conclusion.

In a recent article Humphreys has developed an intriguing proposal for making sense of emergence. The crucial notion for this purpose is what he calls "fusion" and his paradigm for it is quantum nonseparability. In what follows, we will develop this position in more detail, and then discuss its ramifications and limitations. Its ramifications are quite radical; its limitations are substantial. An alternative approach to emergence that involves quantum physics is then proposed.

This is a survey of contemporary work on ‘fictionalism in metaphysics’, a term that is taken to signify both the place of fictionalism as a distinctive anti‐realist metaphysics in which usefulness rather than truth is the norm of acceptance, and the fact that philosophers have given fictionalist treatments of a range of specifically metaphysical notions.

This paper provides a new solution to the epistemic paradox of belief-instability, a problem of rational choice which has recently received considerable attention (versions of the problem have been discussed by — among others — Tyler Burge, Earl Conee, and Roy Sorensen). The problem involves an ideally rational agent who has good reason to believe the truth of something of the form:[Ap] p if and only if it is not the case that I accept or believe p.

Philosophical debates over statistical evidence have long been framed and dominated by L. Jonathan Cohen's Paradox of the Gatecrasher and a related hypothetical example commonly called Prison Yard. These examples, however, raise an issue not discussed in the large and growing literature on statistical evidence – the question of what statistical evidence is supposed to be evidence of. In actual practice, the legal system does not start with a defendant and then attempt to determine if that defendant has committed some (...) unspecified or under-specified act, as these examples appear to suppose. Rather, both criminal and civil litigation start with a sufficiently specified act and then attempt to determine if the defendant has committed it. And when we start with a more fully specified act, the statistics look very different, and these prominent examples no longer present the paradox they are claimed to support. Examining the issue of specification, however, does more than simply undercut the prominent examples in a long and extensive literature. The examination also raises normative issues challenging the legal system's traditional reluctance to base liability on the conjunction of probabilities. (shrink)

This paper involves one crucial assumption; namely, that the statistical predictions of quantum mechanics for Bell's variant of the EPR experiment will continue to be verified as detector efficiencies are improved and the need for coincidence counters is eliminated. This assumption entails that any hidden-variables theory for quantum mechanics must violate Bell's inequality--the inequality derived in Bell (1964). It is shown here that four locality conditions are involved in the derivation of Bell's inequality; and that a violation of any of (...) the four locality conditions will either entail the existence of superluminal influences or the existence of superluminal signals (superluminal influences that can be used to transmit information), if conspiratorial theories can be ruled out. The attempts so far to rule out conspiratorial theories are all found to be rather dubious, but there are other considerations developed here that rule them out convincingly. Finally, it is demonstrated that violations of each of the four locality conditions can be used to transmit information superluminally, if certain auxiliary conditions are satisfied. This is of particular interest because one of these conditions corresponds to a condition dubbed "completeness" by Jon Jarrett. Jarrett and others have suggested that violations of completeness cannot be used to send information superluminally. Demonstrating otherwise is, perhaps, the most significant result obtained in this paper. (shrink)

In their recent ‘The ethical case for non-directed postmortem sperm donation’, Hodson and Parker outline and defend the concept of voluntary non-directed postmortem sperm donation, the idea that men should be able to register their desire to donate their sperm after death for use by strangers since this would offer a potential means of increasing the quantity and heterogeneity of donor sperm. In this response, we raise some concerns about their proposal, focusing in particular on the fact that current methodologies (...) do not make for a reliable way of ensuring that sperm retrieved postmortem has a good chance of leading to conception, which is in turn likely to make potential recipients reluctant to use such sperm. These concerns add to the ethical doubts that attend aspects of the proposal, making the prospect of implementation of such a policy unlikely at best. (shrink)

Kant's distinction between things in themselves and things as they appear, or appearances, is commonly attacked on the ground that it delivers a radical and incoherent ‘two world’ picture of what there is. I attempt to deflect this attack by questioning these terms of dismissal. Distinctions of the kind Kant draws on are in fact legion, and they make perfectly good sense. The way to make sense of them, however, is not by buying into a profligate ontology but by using (...) some rather different tools – surprisingly enough, tools first developed in the area of aesthetics. Once this is done, much of what Kant says begins to look perfectly coherent. In the final part of the paper, I point out that none the less all is not well. Kant's Critical doctrines make it hard for us to accept Kant's own version of this otherwise coherent distinction. (shrink)

Conventional wisdom has it that chaotic behavior is either strongly suppressed or absent in quantum models. Indeed, some researchers have concluded that these considerations serve to undermine the correspondence principle, thereby raising serious doubts about the adequacy of quantum mechanics. Thus, the quantum chaos question is a prime subject for philosophical analysis. The most significant reasons given for the absence or suppression of chaotic behavior in quantum models are the linearity of Schrödinger’s equation and the unitarity of the time-evolution described (...) by that equation. Both are shown in this essay to be irrelevant by demonstrating that the crucial feature for chaos is the nonseparability of the Hamiltonian. That demonstration indicates that quantum chaos is likely to be exhibited in models of open quantum systems. A measure for probing such models for chaotic behavior is developed, and then used to show that quantum mechanics has chaotic models for systems having a continuous energy spectrum. The prospects of this result for vindicating the correspondence principle (or the motivation behind it, at least) are then briefly examined. (shrink)

Two notions of evidence are focused on in this essay, Carnap's positive-relevance notion of evidence (1962, pp. 462 ff.), and Achinstein's notion of potential evidence (1978; and 1983, pp. 322–350). Achinstein creates several interesting examples in his attempt to find faults in Carnap's notion of evidence; his motive, ultimately, is to impel us towards potential evidence. The purpose of this essay is to show that positive relevance is significantly more promising than potential evidence with respect to capturing the scientific sense (...) of the term evidence. This is accomplished by finding faults in the notion of potential evidence, and by defending positive relevance against Achinstein's examples. (shrink)

This chapter contains sections titled: The Aim of Hegel's Science of Society The Method of Hegel's Science of Society Comprehension versus Critique.

In recent years, Duncan Pritchard has developed a position in religious epistemology called quasi‐fideism that he claims traces back to John Henry Newman's treatment of the rationality of religious belief. In this paper, we give three reasons to think that Pritchard's reading of Newman as a quasi‐fideist is mistaken. First, Newman's parity argument does not claim that religious and non‐religious beliefs are on a par because both are groundless; instead, for Newman, they are on a par because both often stem (...) from implicit rather than explicit reasoning. Second, pace Pritchard, Newman's distinction between simple and complex assent does not map onto the Wittgensteinian distinction between groundless hinge commitments and beliefs that flow from these hinges. For Newman, simple and complex assent differ in terms of the believer's level of awareness of their grounds. Third, and finally, Newman does not reject Locke's evidentialism in toto. Instead, he argues that certitude is not restricted to beliefs stemming from intuition and demonstration but often rightly includes probabilistically supported (or fallibly evidenced) beliefs.

Some present-day disagreements in moral philosophy, by E. F. Flower.--Values in the history of ideas, by P. P. Wiener.--Social interests and value, by T. A. Cowan.--Value conflicts and the education of our young, by J. L. Childs.

This moral philosophy text with readings embraces Socrates' observation that ethics is "no small matter, but how we ought to live." How ought we to live? This hard question captures the full range of moral inquiry from traditional moral theory to contemporary moral issues, such as abortion, capital punishment, and war. But there is much more to moral philosophy: How should we be as people? When should we forgive? Are we capable of morality? What about non-western ethics? And most distressing (...) of all, why be moral in the first place? These and other challenging questions show the profundity and inescapable importance of moral philosophy for a life worth living. Life's Hardest Questions combines lively and informative introductory discussions with classic and contemporary writings in moral philosophy. (shrink)
