The Biology of Evil: Nietzsche on Degeneration (Entartung) and Jewification.Ken Gemes -2021 -Journal of Nietzsche Studies 52 (1):1-25.detailsThis article examines Nietzsche's use of the rhetorics of degeneration and “jewification”, arguing that he often, though not always, uses them in unconventional ways to undermine his audience's comfortable assumptions about their values and identity. In doing so, he challenges the idea of health as the isolation of alleged infectious elements and promotes the ideal of a “great health” predicated on the incorporation of such elements into a greater whole.
Nietzsche on Free Will, Autonomy and the Sovereign Individual.Ken Gemes -2009 - In Ken Gemes & Simon May,Nietzsche on freedom and autonomy. New York: Oxford University Press. pp. 321-338.details[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)
Freud and Nietzsche on sublimation.Ken Gemes -2009 -Journal of Nietzsche Studies 38 (1):38-59.detailsThe 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)
Who are Nietzsche’s Christians?Ken Gemes -forthcoming -Inquiry: An Interdisciplinary Journal of Philosophy.detailsNietzsche famously rails against Christian virtues such as humility and compassion. Yet he is well aware that historical Christians, especially those in positions of power, typically preached such values but did not practice them. This raises the question whom Nietzsche is really targeting in his animadversions against Christian virtues. The answer developed here is that his real targets are his contemporaries, including atheist, socialists such as Eugen Dühring, who, with their advocacy of egalitarian, democratic social and political policies, are trying (...) to implement the values Christians long preached but rarely practiced. In nominating moderns, including those who seek the realization of enlightenment liberal democratic values, rather than past Christians, as Nietzsche’s real targets we create space for reconciling Nietzsche’s claim that he accepts the past (as embodied in his doctrine of amor fati) with his project of seeking to open up new possibilities for the future. In the concluding sections the questions are raised to what extent do Nietzsche’s attacks on Christian virtues exhibit the very ressentiment he so vehemently criticises as a source of Christian values, and whether his criticism of the modern social and political implementation of those values is really supported by his own values.

Hypothetico-deductivism, content, and the natural axiomatization of theories.Ken Gemes -1993 -Philosophy of Science 60 (3):477-487.detailsIn 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)

Other sections are devoted to his life, his relations to other philosophers, and his individual works.
Nietzsche.Ken Gemes &Christoph Schuringa -2012 - In Tom P. S. Angier,Ethics: the key thinkers. London: Bloomsbury Academic.detailsNietzsche 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.

Hypothetico-Deductivism: The Current State of Play; The Criterion of Empirical Significance: Endgame.Ken Gemes -1998 -Erkenntnis 49 (1):1 - 20.details: 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.

Horwich, Hempel, and hypothetico-deductivism.Ken Gemes -1990 -Philosophy of Science 57 (4):699-702.detailsIn 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)

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.

In it a new notion of content is used to explicate Michael Friedman's notion of "k-atomicity," and to explicate the notion of the surplus content of hypothesis h relative to evidence e. From this basis an analysis of unification as theoretical reduction is advanced. A second notion of unification, unification as reconciling prima facie incompatible statements, is introduced again with the aid of this new notion of content. (...) More generally, it is argued that rather than seek the essence of scientific explanation we should carefully catalog the various distinct explanatory virtues. Finally it is argue that in particular philosophical explanations put a high premium on the quality of unification through showing how to make compatible seemingly irreconcilable claims. (shrink)
Postmodernism’s Use and Abuse of Nietzsche.Ken Gemes -2001 -Philosophy and Phenomenological Research 62 (2):337-360.detailsI 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)

Bootstrapping and Content Parts.Ken Gemes -2006 -Erkenntnis 64 (3):345-370.detailsChristensen [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)
Carnap-confirmation, content-cutting, & real confirmation.Ken Gemes -1989detailsThe 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)
Who are Nietzsche's slaves?Ken Gemes -2024 -European Journal of Philosophy 32 (4):1116-1129.detailsThis paper argues that Nietzsche is deliberately imprecise in his characterization of what he calls the slave revolt in morality. In particular, none of the people or groups he nominates as instigators of the slave revolt, namely, Jewish priests, the Jewish people, the prophets, Jesus, and Paul, were literally slaves. Analysis of Nietzsche's texts, including his usage of the term “slaves,” and his sources concerning those he nominates as the instigators of the slave revolt, make clear that Nietzsche knew none (...) of these were literally slaves. He calls it a slave revolt because he means that the propagators of that revolt preached what he takes to be the slavish values, including, humility, compassion, obedience, and lack of egoism. He uses the high loaded term “slave” both to disparage those values and, most importantly, to bring home to his readers the message that they, as inheritors of Judeo‐Christian values, actual adhere to and practice the debased slavish values preached, but not necessarily practiced, by the original instigators of the slave revolt. For Nietzsche, his readers are strangers to themselves, thus he notes “slavery is everywhere visible, although it does not call itself as such.”. (shrink)

Content & Watkins's account of natural axiomatizations.Ken Gemes -2006 -Dialectica 60 (1):85–92.detailsThis 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)
The problem of evil and its solution.Ken Gemes -manuscriptdetailsThe 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)
Strangers to Ourselves: Nietzsche on The Will to Truth, The Scientific Spirit, Free Will, and Genuine Selfhood.Ken Gemes -unknowndetailsOn 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)

Replies to Commentators on “The Biology of Evil”.Ken Gemes -2021 -Journal of Nietzsche Studies 52 (1):65-77.detailsIn this article, I reply to commentators Leonard Feldblyum, Robert Holub, and David Owen on my article “The Biology of Evil.” While I concede that Nietzsche often invoked standard degenerationist rhetoric about breeding, I argue that Nietzsche, unlike other degenerationists, never offered any concrete plans for such breeding and was not interested in raising the capacities of average citizens, but rather was concerned with the exceptional few. I argue that these “strokes of luck” do not readily lend themselves to planned (...) breeding programs. I concede that Nietzsche did not favor societies that allowed for the integration of foreign elements, but rather some alternation between regimented hierarchical societies and motley societies. However, against Holub's and Feldblyum's contention that Nietzsche was interested in the alleged Jewish problem of his day, I expand on my claim that, for Nietzsche, the current malaise is more a product of the workings of the ancient than the modern Jews. And against Owen and Holub, I defend the claim that degeneration theory was fundamentally Manichean and that Nietzsche resisted this Manichean tendency. (shrink)
A new theory of content I: Basic content. [REVIEW]Ken Gemes -1994 -Journal of Philosophical Logic 23 (6):595 - 620.detailsPhilosophers 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.

Inductive skepticism and the probability calculus I: Popper and Jeffreys on induction and the probability of law-like universal generalizations.Ken Gemes -1997 -Philosophy of Science 64 (1):113-130.details1. Introduction. Attempts to utilize the probability calculus to prove or disprove various inductive or inductive skeptical theses are, I believe, highly problematic. Inductivism and inductive skepticism are substantive philosophical positions that do not allow of merely formal proofs or disproofs. Often the problems with particular alleged formal proofs of inductive or inductive sceptical theses turn on subtle technical considerations. In the following I highlight such considerations in pointing out the flaws of two proofs, one an alleged proof of an (...) inductive sceptical conclusion due to Karl Popper, the other an alleged proof of an inductivist thesis originally due to Harold Jeffreys and later advocated by John Earman. Surprisingly, in examining Popper's argument it is shown that certain apparently weak premises, often embraced by both inductivists and deductivists, lend themselves to inductive conclusions. However it is argued that those premises are still philosophically substantive and not amenable to a purely formal demonstration. The lesson to be learnt here is twofold. First, we need to be very careful in determining which formal theses entail, and which are entailed by, inductive skepticism and inductivism. Second, we need to take great care in laying out and examining the assumptions presumed in formal arguments directed for and against such formal theses. In a follow up article I will consider various attempts by David Stove and Karl Popper and David Miller to identify the exact content of inductive skepticism and propose a new identification based on the theory of content developed in Gemes 1994. Finally I will compare this new version with that proposed recently in Alberto Mura 1990. (shrink)
Irrelevance: Strengthening the Bayesian requirements.Ken Gemes -2007 -Synthese 157 (2):161-166.detailsBayesians 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)
The world in itself: Neither uniform nor physical.Ken Gemes -1987 -Synthese 73 (2):301 - 318.detailsSince 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.
