Popper’s original definition of verisimilitude in terms of comparisons of truth content and falsity content has known counter-examples. More complicated approaches have met with mixed success. This paper uses a new account of logical content to develop a definition of verisimilitude that is close to Popper’s original account. It is claimed that Popper’s mistake was to couch his account of truth and falsity content in terms of true and false consequences. Comparison to a similar approach by Schurz and Wiengartner show (...) certain advantages of this new approach. (shrink)

This paper develops a semantical model - theoretic account of (logical) content complementing the syntactically specified account of content developed in "A New Theory of Content I", JPL 23: 596-620, 1994. Proofs of Completeness are given for both propositional and quantificational languages (without identity). Means for handling a quantificational language with identity are also explored. Finally, this new notion of content is compared, in respect of both logical properties and philosophical applications, to alternative partitions of the standard consequence class relation (...) proposed by Stelzner, Schurz and Wiengartner.

In Gemes (1990) I examined certain formal versions of hypothetico-deductivism (H-D) showing that they have the unacceptable consequence that "Abe is a white raven" confirms "All ravens are black"! In Gemes (1992) I developed a new notion of content that could save H-D from this bizarre consequence. In this paper, I argue that more traditional formulations of H-D also need recourse to this new notion of content. I present a new account of the vexing notion of the natural axiomatization of (...) a theory. The notion is used to construct a form of H-D that allows for the type of selective confirmation without which Glymour (1980a,b) claims H-D is hopeless. (shrink)

The principal aim of this volume is to elucidate what freedom, sovereignty, and autonomy mean for Nietzsche and what philosophical resources he gives us to re ...

In this astonishingly rich volume, experts in ethics, epistemology, philosophy of mind, political theory, aesthetics, history, critical theory, and hermeneutics bring to light the best philosophical scholarship on what is arguably Nietzsche's most rewarding but most challenging text. Including essays that were commissioned specifically for the volume as well as essays revised and edited by their authors, this collection showcases definitive works that have shaped Nietzsche studies alongside new works of interest to students and experts alike. A lengthy introduction, annotated (...) bibliography, and index make this an extremely useful guide for the classroom and advanced research. (shrink)

: Any precise version of H-D needs to handle various problems, most notably, the problem of selective confirmation: Precise formulations of H-D should not have the consequence that where S confirms T, for any T', S confirms T&T'. It is the perceived failure of H-D to solve such problems that has lead John Earman to recently conclude that H-D is "very nearly a dead horse". This suggests the following state of play: H-D is an intuitively plausible idea that breaks down (...) in the attempt to give it a precise formulation. Indeed I think that fairly captures the view among specialists in the field of confirmation theory. Here I argue that the truth about H-D is largely the reverse: H-D can be given a precise formulation that avoids the longstanding technical problems, however, it relies on a fundamentally unsound philosophical intuition. The bulk of this paper involves reviewing the problems affecting previous attempts at giving precise formulations of H-D and displaying some recent versions that can handle these problems. It then briefly explains why the basic intuition behind H-D is itself unsound, namely, because H-D involves a tacit assumption of inductive scepticism. Finally, the historical relation between H-D and the positivists' quest for a criterion of empirical significance will be reconsidered with the surprising result that having glossed H-D as fundamentally unsound it is concluded that a sound version of the criterion of empirical significance is now available. The demarcation criterion, the positivists' philosopher's stone that serves to separate claims with empirical significance from claims lacking empirical significance having finally been found, it is argued that we should regard empirical significance as just one among a variety of virtues and not follow the positivists in taking it to be a sin qua non for all meaningful statements.

Various possibilities, that one is dreaming, that one is being deceived by a deceitful demon, that one is a brain in the vat being stimulated to think one has a body and is in a regular world, have been invoked to show that all one's experience-based beliefs might be false.

[Ken Gemes] In some texts Nietzsche vehemently denies the possibility of free will; in others he seems to positively countenance its existence. This paper distinguishes two different notions of free will. Agency free will is intrinsically tied to the question of agency, what constitutes an action as opposed to a mere doing. Deserts free will is intrinsically tied to the question of desert, of who does and does not merit punishment and reward. It is shown that we can render Nietzsche's (...) prima facie conflicting assertions regarding free will compatible by interpreting him as rejecting deserts free will while accepting the possibility of agency free will. It is argued that Nietzsche's advances an original form of compatibilism which takes agency free will to be a rare achievement rather than a natural endowment. /// [Christopher Janaway] This paper aims to distinguish a conception of 'free will' that Nietzsche opposes (that of the pure agent unaffected by contingencies of character and circumstance) and one that he supports. In Human, All Too Human Nietzsche propounds the 'total unfreedom' of the will. But by the time of Beyond Good and Evil and the Genealogy he is more concerned (a) to trace the affective psychological states underlying beliefs in both free will and 'unfree will', (b) to suggest that the will might become free in certain individuals, a matter of having a consistent strong character, self-knowledge, and ability to create values. The paper explores the kind of autonomy required in agents who would 'revalue' existing values. (shrink)

An international team of scholars offer a broad engagement with the thought of Friedrich Nietzsche. They discuss the main topics of his philosophy, under the headings of values, epistemology and metaphysics, and will to power. Other sections are devoted to his life, his relations to other philosophers, and his individual works.

Philosophers of science as divergent as the inductivist Carnap and the deductivist Popper share the notion that the (logical) content of a proposition is given by its consequence class. I claim that this notion of content is (a) unintuitive and (b) inappropriate for many of the formal needs of philosophers of science. The basic problem is that given this notion of content, for any arbitrary p and q, [(p ∨ q)] will count as part of the content of both p (...) and q. In other words, any arbitrary p and q share some common content. This notion of content has disastrous effects on, for instance, Carnap's attempts to explicate the notion of confirmation in terms of probabilistic favorable relevance, and Popper's attempts to define verisimilitude. After briefly reviewing some of the problems of the traditional notion of content I present an alternative notion of (basic) content which (a) better fits our intuitions about content and (b) better serves the formal needs of philosophers of science.

Bayesians standardly identify irrelevance with probabilistic irrelevance. However, there are cases where e is probabilistically irrelevant to h but intuitively e is relevant to h. For instance, ‘Die A came up 1 and die B came up 1, 3, 5 or 6’ is probabilistically irrelevant to ‘Die A came up odd and die B came up even’, yet, intuitively, it is not, irrelevant to that claim, in the sense that ‘Sydney has a harbour Bridge’ is irrelevant to it. In the (...) context of decision making this notion of irrelevance combined with such rules as ‘Do not expend resources on irrelevant evidence’ leads to bad results. A stronger notion of irrelevance fitting our intuitions and the contexts of decision making is proposed: e is irrelevant to h if and only if every part of e is probabilistically irrelevant to every part of h. However, we need to take care in determining what counts as part of a statement. (shrink)

Alleged counter-examples deployed in Park [Erkenntnis 60: 229–240] against the account of selective hypothetico-deductive confirmation offered in Gemes [Erkenntnis 49: 1–20] are shown to be ineffective. Furthermore, the reservations expressed in Gemes [ibid] and [Philosophy of Science 62: 477–487] about hypothetico-deductivism are retracted and replaced with the conclusion that H-D is a viable account of confirmation that captures much of the practice of working scientists. However, because it cannot capture cases of inference to the best explanation and cases of the (...) observational confirmation of statistical hypotheses, it is concluded that H-D cannot supply a complete theory of confirmation.

Logical Positivism, could not be said to be au courant as a philosophical movement.1 Indeed not only is the movement no longer in existence, it's projects are no longer central to philosophical investigations, even to the investigations of those who specialize in the philosophy of science. If Positivism has been making a comeback it is primarily as an object of historical inquiry, perhaps as a means to answering the question of how we got from there (our forefathers' primary philosophical interests (...) and presuppositions) to here (our own current philosophical interests and presuppositions). The historical study of Positivism is indeed a worthwhile pursuit. However I think we still have room for a genuine inquiry into the possibility of completing at least some of the Positivists' projects. To borrow one of Carnap's most famous metaphors; besides the external project of asking what motivated the Positivists, what were their influences and basic presumptions, and what influence did they have, we can ask the internal question of how might their projects be completed. In attempting to complete some of those projects we may need recourse to methods, for instance, new types of logical constructions, that were unavailable to the Positivists. Such recourse will be legitimate as long as the methods are of a kind with those employed by the Positivists themselves. The Logical Positivists of course had many different projects that one might consider worthy of pursuit. Amongst the most prominent of these are the construction of a verificationist account of meaning, a criterion for demarcating science from metaphysics, various accounts of confirmation, and accounts of the status and nature of logical, mathematical, and scientific truths. Often these projects, for reasons good and bad, are run together by both the Positivists and their critics. To find what is worth preserving in Positivism one sometimes needs to tease them apart.

In his paper, "Explanations of Irrelevance" (1983), Paul Horwich proposes an amended version of hypothetico-deductivism, (H-D * ). In this discussion note it is shown that (H-D * ) has the consequence that "A is a non-black raven" confirms "All ravens are black" relative to any tautology! It is noted that Horwich's (H-D * ) bears a strong resemblance to Hempel's prediction criterion of confirmation and that the prediction criterion faces the same obstacle. A related problem for hypothetico-deductivism in its (...) simplest form--that is, E confirms H iff E is an (observational) consequence of H--is displayed. The discussion concludes with a suggestion about how (H-D * ) and simple hypothetico-deductivism might be amended in order to avoid these results. (shrink)

The problem of evil can be captured by the following four statements which taken together are inconsistent: 1) God made the world 2) God is a perfect being 3) A perfect being would not create a world containing evil 4) The world contains evil Traditional attempts to grapple with this problem typically center on rejecting (3). Thus Descartes, following Augustine, rejects (3), arguing that evil is the result of man’s exercise of his free will. However, given Descartes plausible claim that (...) God could have created man in such a way that through exercising his free will man comes to only virtuous actions, it is not clear how the problem is solved. Descartes also repeats the Augustinian orthodoxy that though the world contains evil it does not contain it as a positive existence; evil has no real being but is simply the reflection of the inherent lack of full-being in merely finite individuals. Again, that this is a solution is open to serious doubt. (shrink)

The attempt to explicate the intuitive notions of confirmation and inductive support through use of the formal calculus of probability received its canonical formulation in Carnap's The Logical Foundations of Probability. It is a central part of modern Bayesianism as developed recently, for instance, by Paul Horwich and John Earman. Carnap places much emphasis on the identification of confirmation with the notion of probabilistic favorable relevance. Notoriously, the notion of confirmation as probabilistic favorable relevance violates the intuitive transmittability condition that (...) if e confirms h and h' is part of the content of h then e confirms h'. This suggests that, pace Carnap, it cannot capture our intuitive notions of confirmation and inductive support. Without transmittability confirmation losses much of its intrinsic interest. If e, say a report of past observations, can confirm h, say a law-like generalization, without that confirmation being transmitted to those parts of h dealing with the as yet unobserved, then it is not clear why we should be interested in whether h is confirmed or not. The following paper rehearses these difficulties and then proposes a new probabilistic account of confirmation that does not violate the transmittability condition. (shrink)

This paper briefly recounts the importance of the notion of natural axiomatizations for explicating hypothetico‐deductivism, empirical significance, theoretical reduction, and organic fertility. Problems for the account of natural axiomatizations developed by John Watkins in Science and Scepticism and the revised account developed by Elie Zahar are demonstrated. It is then shown that Watkins's account can be salvaged from various counter‐examples in a principled way by adding the demand that every axiom of a natural axiomatization should be part of the content (...) of the theory being axiomatized. The crucial point here is that content cannot simply be identified with the set of logical consequences of a theory, but must be restricted to a proper subset of the consequence set. It is concluded that the revised Watkins account has certain advantages over the account of natural axiomatizations offered in Gemes. (shrink)

On the Genealogy of Morals contains the puzzling claim that the will to truth is the last expression of the ascetic ideal. Part I of this essay argues that Nietzsche’s claim is that our will to truth functions as a tool allowing us to take a passive stance to the world, leading us to repress and split off part of our nature. Part II deals with Nietzsche’s account of the sovereign individual and his related, novel, account of free will. Both (...) these accounts hinge on the notion of the self as an integrated whole. In contrasting the integrated sovereign individual, who has genuine free will, and we splintered moderns, Nietzsche aims to unsettle us with uncanny suggestion that we have no genuine selves. Part III shows that the invocation of the uncanny is a central strategy Nietzsche uses to bring home his disturbing message that we are strangers to ourselves. (shrink)

Christensen [Philosophy of Science, 50: 471–481, 1983] and [Philosophy of Science, 57: 644–662, 1990] provides two sets of counter-examples to the versions of bootstrap confirmation for standard first-order languages presented in Glymour [Theory and Evidence, Princeton University Press, Princeton, 1980] and [Philosophy of Science, 50: 626–629, 1983]. This paper responds to the counter-examples of Christensen [Philosophy of Science, 50: 471–481, 1983] by utilizing a new notion of content introduced in Gemes [Journal of Philosophical Logic, 26, 449–476, 1997]. It is claimed (...) that this response is better motivated and more effective than that presented in Glymour [Philosophy of Science, 50: 626–629, 1983]. It is then argued that while this response meets some of the counter-examples of Christensen [Philosophy of Science, 57: 644–662, 1990] two of those counter-examples, though not unanswerable, suggest the need for a substantial reformulation of the formal versions of bootstrapping. The essay proceeds with such a reformulation, arguing that this new formulation better fits the philosophical insights that originally motivated bootstrapping than do Glymour’s earlier formulations. In the concluding sections some alternative solutions to the problem posed by the Christensen counter-examples are discussed. (shrink)

Since Hume, philosophers of induction have debated the question of whether we have any reason for assuming that nature is uniform. This debate has always presumed that the uniformity hypothesis is itself coherent. In Part 1 of the following I argue that a proper appreciation of Nelson Goodman's so-called grue-green problem1 should lead us to the conclusion that the uniformity hypothesis, under its usual interpretation as a strictly ontological thesis, is incoherent. In Part 2 I argue that further consideration of (...) the grue-green problem leads to the conclusion that certain popular versions of the thesis of physical supervenience/the primacy of physics, under their usual interpretation as strictly ontological theses, are false. In Part 3 I argue that the notions of natural kinds and nature's joints should not be taken as ontologically objective notions but as interest relative. Together Parts 1, 2, and 3 provide support for the Nietzsche-Goodman thesis that philosophers are prone to mistakenly identify as absolute, mind and language independent, features of the world which are in fact only features of a particular discourse, or of the world relative to a particular discourse.

The notion of sublimation is essential to Nietzsche and Freud. However, Freud's writings fail to provide a persuasive notion of sublimation. In particular, Freud's writings are confused on the distinction between pathological symptoms and sublimation and on the relation between sublimation and repression. After rehearsing these problems in some detail, it is proposed that a return to Nietzsche allows for a more coherent account of sublimation, its difference from pathological symptoms, and its relation to repression. In summary, on Nietzsche's account, (...) while repression and pathological symptoms involve a disintegration , sublimation involves integration. The article concludes with a brief consideration of some post-Freudian accounts of sublimation that represent a return to a more Nietzschean approach. (shrink)

Book synopsis: A Companion to Schopenhauer provides a comprehensive guide to all the important facets of Schopenhauer’s philosophy. The volume contains 26 newly commissioned essays by prominent Schopenhauer scholars working in the field today.

I focus on Nietzsche’s architectural metaphor of self-construction in arguing for the claim that postmodern readings of Nietzsche misunderstand his various attacks on dogmatic philosophy as paving the way for acceptance of a self characterized by fundamental disunity. Nietzsche’s attack on essentialist dogmatic metaphysics is a call to engage in a purposive self-creation under a unifying will, a will that possesses the strength to reinterpret history as a pathway to “the problem that we are”. Nietzsche agrees with the postmodernists that (...) unity is not a pre-given, however he would disavow their rejection of unity as a goal. Where the postmodernists celebrate “the death of the subject” Nietzsche rejects this valorization of disunity as a form of Nihilism and prescribes the creation of a genuine unified subjectivity to those few capable of such a goal. Post modernists are nearer Nietzsche’s idea of the Last Man than his idea of the Overman. (shrink)

Nietzsche never presented a worked-out normative ethical theory and appeared to regard any attempt to do so as woefully misguided. He poured scorn on the main contenders for such a theory in his day, and in ours – Kantian ethics and utilitarianism. Moreover, he repeatedly referred to himself as an 'immoralist' and gave one of his books the title Beyond Good and Evil, thus seeming only to confirm the impression that he was more interested in demolishing, and even abolishing morality (...) altogether than in making any constructive contribution to the subject. While the topic of morality appears as a central and almost obsessive interest in his works – especially in the sequence of books from Daybreak: Thoughts on the Prejudices of Morality (1881) to On the Genealogy of Morality (1887) – it generally does so as the target of relentless criticism. Many have concluded, not surprisingly, that Nietzsche, rather than being interested in replacing an existing conception of morality with a better one of his own, was in the business of advising us to abandon morality altogether – to live, in some sense, without morality.

This article explores Nietzsche’s interest in perspectives. Various epistemological and semantic interpretations of perspectivism are considered, including readings of it as a semantic claim about the nature of truth, and readings of perspectivism as an epistemological claim, that all knowledge depends on interests or affect. Nietzsche’s perspectivism is best interpreted as a kind of psychobiological claim that serves as an extension of his claim that all life is will to power. On this reading, perspectivism has neither semantic significance nor epistemological (...) import. (shrink)
