Nietzsche: Philosophy of Science

Beginning with the Untimely Meditations (1873) and continuing until his final writings of 1888-9, Nietzsche refers to humility (Demuth or a cognate) in fifty-two passages and to modesty (Bescheidenheit or a cognate) in one hundred and four passages, yet there are only four passages that refer to both terms. Moreover, perhaps surprisingly, he often speaks positively of modesty, especially in epistemic contexts. These curious facts might be expected to lead scholars to explore what Nietzsche thinks of humility and modesty, but (...) to date there have been no systematic analyses of Nietzsche’s reflections on these dispositions. In this chapter, I fill that gap in the literature using semantic network analysis and systematically-guided close-reading. In so doing, I show that Nietzsche sharply distinguished between humility and modesty, considering the former a vice (for certain types of people in certain contexts) and the latter a virtue (again, for certain types of people in certain contexts).

Nietzsche’s attitude toward science is ambivalent: he remarks approvingly on its rigorous methodology and adventurous spirit, but also points out its limitations and rebukes scientists for encroaching onto philosophers’ territory. What does Nietzsche think is science’s proper role and relationship with philosophy? I argue that, according to Nietzsche, philosophy should set goals for science. Philosophers’ distinctive task is to ‘create values’, which involves two steps: (1) envisaging ideals for human life, and (2) turning those ideals into prescriptions for behaviour and (...) societal organization. To accomplish step (2), philosophers should delegate scientists to investigate what moral rules and social arrangements have best advanced this ideal in the past or might in the future. (shrink)

La “visión del mundo” (Weltanschauung) es una cuestión que ha sido pasado por alto por un gran número de investigadores en el pensamiento de Nietzsche, aunque aparece con frecuencia en sus escritos. Pocos intérpretes han tocado esta noción, y dirigen únicamente su atención en puntos muy concretos de vista, destacando algunos aspectos menos esenciales de la misma. Parece que el concepto de Weltanschauung nunca ha sido considerado como un objeto independiente dentro de la obra de Nietzsche. Este trabajo pretende elaborar (...) un recorrido interpretativo, resaltando su importancia y, sobre todo, el lugar que posee dentro de uno de sus primeros escritos, El Nacimiento de la Tragedia.

Nietzsche sometimes praises the drive to order—to simplify, organize, and draw clear boundaries—as expressive of a vital "classical" style, or an Apollonian artistic drive to calmly contemplate forms displaying "epic definiteness and clarity." But he also sometimes harshly criticizes order, as in the pathological dialectics or "logical schematism" that he associates paradigmatically with Socrates. I challenge a tradition that interprets Socratism as an especially one-sided expression of, or restricted form of attention to, the Apollonian: they are more radically disparate. Beyond (...) strengthening the case for this basic point, I develop a distinctive account of what, exactly, distinguishes the Apollonian-classical and Socratic forms of order. To this end, I advance interrelated interpretations of Apollonian-classical simplicity and the "cold" calm that it elicits, by contrast to superficially similar Socratic phenomena. This illuminates Nietzsche's broader ambivalence toward science, in part by clarifying the nature and value of an idealized Apollonian science. (shrink)

Perhaps the most fundamental disagreement concerning Nietzsche's view of metaphysics is that some commentators believe Nietzsche has a positive, systematic metaphysical project, and others deny this. Those who deny it hold that Nietzsche believes metaphysics has a special problem, that is, a distinctively problematic feature that distinguishes metaphysics from other areas of philosophy. In this paper, I investigate important features of Nietzsche's metametaphysics in order to argue that Nietzsche does not, in fact, think metaphysics has a special problem. The result (...) is that, against a long-standing view held in the literature, we should be reading Nietzsche as a metaphysician. (shrink)

El artículo se propone elucidar el papel que juegan los usos de “raza” en los escritos de Nietzsche, situándolos e interpretándolos en conjunto con el léxico de transformación del ser humano y de su crítica de la cultura. Para ello, se estudia su empleo junto a otros conceptos fronterizos e ideas análogas como el tratamiento de la cuestión judía, su crítica del nacionalismo, la figura de los buenos europeos, la metáfora de la bestia rubia, los tipos humanos y el pensamiento (...) de la cría. Se concluye que “raza” posee un indudable carácter fisiológico y evolutivo, pero a través del proceso de incorporación (Einverleibung), el ámbito de la cultura y la moral intervienen de manera fundamental en su conformación, y como concepto, forma parte del mismo proyecto de transvaloración de los valores, la reforma de la cultura y de la humanidad. El artículo finaliza con una reflexión de la llamada a superar la raza (Über-Rasse). (shrink)

Friedrich Nietzsche was among the figures from the history of nineteenth century philosophy that, perhaps surprisingly, some of the Vienna Circle’s members had presented as one of their predecessors. While, primarily for political reasons, most Anglophone figures in the history of analytic philosophy had taken a dim view of Nietzsche, the Vienna Circle’s leader Moritz Schlick admired and praised Nietzsche, rejecting what he saw as a misinterpretation of Nietzsche as a militarist or proto-fascist. Schlick, Frank, Neurath, and Carnap were in (...) different ways committed to the view that Nietzsche made a significant contribution to the overcoming of metaphysics. Some of these philosophers praised the intimate connection Nietzsche drew between his philosophical outlook and empirical studies in psychology and physiology. In his 1912 lectures on Nietzsche, Schlick maintained that Nietzsche overcame an initial Schopenhauerian metaphysical-artistic phase in his thinking, and subsequently remained a positivist until his last writings. Frank and Neurath made the weaker claim that Nietzsche contributed to the development of a positivistic or scientific conception of the world. Schlick and Frank took a further step in seeing the mature Nietzsche as an Enlightenment thinker. (shrink)

I examine three kinds of criticism directed at philosophical genealogy. I call these substantive, performative, and semantic. I turn my attention to a particular substantive criticism that one may launch against essay two of On the Genealogy of Morals that turns on how Nietzsche answers “the time-crunch problem”. On the surface, there is evidence to suggest that Nietzsche accepts a false scientific theory, namely, Lamarck’s Inheritability Thesis, in order to account for the growth of a new human “organ”—morality. I demonstrate (...) that the passages interpreted by some scholars to prove that Nietzsche is a Lamarckian can be reinterpreted along Darwinian lines. I demonstrate that Nietzsche hits upon the right drivers of phenotypical change in humans, namely, torture and enclosures (e.g., walls of early states), but misinterprets their true impact. Nietzsche believes that these technologies are responsible for producing what I call “culture-serving memory” and the bad conscience by causing emotions that once were expressed outwardly to turn inward causing the “psychological digestion” of the human animal. In reality, however, these mechanisms are conducive to breeding a particular type of individual, namely, one who is docile, by introducing artificial and unconscious selective pressures into the environment of early humans. In showing that Nietzsche’s genealogical account of memory and bad conscience is not underpinned on a false scientific theory and is consistent with Neo-Darwinism, I deflect a potentially fatal blow regarding the veracity of Nietzsche’s genealogies. -/- .

Abstract Both the subject of science and the notion of creativity in Nietzsche have not been studied with the attention they deserve. The subject of science, however, can be considered a thread of research that is attracting the attention of a large number of philosophers. The notion of creativity, for its part, occupies, among other notions, a little known place within the interests that revolve around the figure of the thinker of Röcken. Therefore, we intend to develop a study of (...) the concept of science in Nietzsche focusing on an analysis of his criticism, to pose the gaze on the subject of Darwinism. Creativity will be studied in light of Nietzsche works and later in nexus with science. The relationship between these themes allows a novel approach to the study of science in Nietzsche and, therefore, to perceive its possible consequences. (shrink)

My dissertation brings into conversation two thinkers who are seldom considered together and highlights previously unnoticed similarities in their critical responses to scientism, which was just as prevalent in the late nineteenth century as it is today. I analyze this attitude as consisting of two linked propositions. The first, which Nietzsche calls “the unconditional will to truth,” is that the aims of science, discovering truth and avoiding error, are the most important human aims; and the second is that no practice (...) other than science can achieve them. Both Nietzsche and James criticize the unconditional will to truth for privileging a transcendent ideal over the demands of human life. This unconditional will regards truth as valuable in itself and demands that we pursue it under all circumstances—even if that demand comes into conflict with other values. I lay out the ways in which Nietzsche and James view the value of truth and the imperative to pursue it as conditional on its promotion of human flourishing. In response to the second proposition of scientism, both philosophers argue that science can neither tell us what we should value, nor fully account for the value we in fact find in certain objects, activities, and experiences. And crucially, science cannot tell us whether or why its own goal of attaining truth is valuable. Nietzsche and James reach different conclusions about what is ultimately valuable, and whether traditional religious belief is defensible in light of the discoveries of science. Nonetheless, the hitherto unappreciated similarities I have uncovered in their arguments show that principled opposition to scientism need not be associated with any particular moral or religious viewpoint. This analysis is not only of historical interest: those who consider scientism to be ill-founded and intellectually confining can take some cues from our nineteenth-century predecessors’ strategies for combating it.

Kyiv-Mohyla Seminar on the History of Philosophy was established by the Kyiv-Mohyla Academy’s Department of Philosophy and Religious Studies (in co-operation with Ukrainian Philosophical Foundation) in 2003. In this yearly seminar, the Department’s members as well as the historians of philosophy from other academic institutions regularly take part. Since 2003, 16 meetings of the seminar took place. They were focused on such topics as “Historiography of Philosophy in Ukraine: Current State and Perspectives” (2003), “Actual Problems of the Source Studies in (...) the Historiography of Philosophy” (2004), “The Problem of Text Interpretation in the Historiography of Philosophy” (2005), “Dmytro Chyzhevskyi as a Historian of Philosophy” (2006), “Historiography of Philosophy in Ukraine: Current State and Perspectives” (2007), “The Problem of Method in the Historiography of Philosophy” (2007), “Oleksii Losiev: Personality and Heritage (to the 115 th Anniversary of His Birth)” (2008), “Methodology of the Historiography of Philosophy: Actual Strategies” (2008), “Wilhelm Windelband as a Philosopher and Historian of Philosophy (to the 160 th Anniversary of His Birth)” (2008), “Hegel’s Heritage in the Mirror of Interpretations” (2009), “The Studies on the History of Philosophy: New Generation” (2010, 2011), “Kant’s Criticism from the perspective of Wolf’s dogmatism” (2012), “The Reception of Indian Philosophy in Ukraine: 1840s–1930s” (2013), “Did Kant Answer the Question on What a Man Is?” (2016). The proceedings of the early three meetings were published in a special volume (Tkachuk, 2006). The current issue of “NaUKMA Research Papers in Philosophy and Religious Studies” contains the proceedings of the sixteenth meeting of Kyiv-Mohyla Seminar on the History of Philosophy, which took place at the National University of Kyiv-Mohyla Academy on February 1, 2017. The main speaker was Dr. Taras Lyuty, while the co-speakers included Dr. Mykhailo Minakov and Dr. Vakhtang Kebuladze. The meeting was conducted by Prof. Vadym Menzhulin. The audio recording of the meeting was deciphered by a PhD-student Taras Fostiak. (shrink)

This article concerns whether Nietzsche is sympathetic to monism about concrete objects, the heterodox metaphysical view that there is exactly one concrete object. I first dispel prominent reasons for thinking that Nietzsche rejects monism. I then develop the most compelling arguments for monism in Nietzsche’s writings and check for soundness. The arguments seem to be supported by the texts, but they have not been developed in the literature. Despite such arguments, I suggest that Nietzsche is actually not sympathetic to monism (...) about objects—but his reasons for siding against monism are not at all obvious. The result should be a new understanding of some of Nietzsche’s fundamental ontological commitments. (shrink)

Those who have emphasised Nietzsche's naturalism have often claimed that he emulates natural scientific methods by offering causal explanations of psychological, social, and moral phenomena. In order to render Nietzsche's method consistent with his methodology, such readers of Nietzsche have also claimed that his objections to the use of causal explanations are based on a limited scepticism concerning the veracity of causal explanations. My contention is that proponents of this reading are wrong about both Nietzsche's methodology and his method. I (...) argue for this by: first, showing that Nietzsche was suspicious of causal explanations not only on sceptical grounds but also for reasons provided by his psychological analysis of our tendency to look for causes; and second, arguing for a non-causal interpretation of Nietzsche's approach to psychological explanation.

Anthony K. Jensen has successfully undertaken an essential project for the fields of Nietzsche studies and philosophy of history. In his interpretation of Nietzsche's second "Untimely Meditation," On the Uses and Disadvantages for Life[1] (henceforth HL), he demonstrates an attention to detail and meticulousness sometimes bordering on obsessiveness. This textual work is based on Jensen's comprehensive familiarity with the philosophical, philological, and historiographic culture in which Nietzsche was trained and to which he was in part responding. Unlike many Anglophone philosophers (...) interested in Nietzsche, Jensen is fully at home with German language and idiom. He combines this linguistic facility with philological expertise and encyclopedic archival research to bring sober clarity to a field often plagued by flights of interpretive speculation. Jensen is knowledgeable of not only the Anglophone but also the Germanophone secondary literatures, and he uses this expertise like a wide-angle lens to give his readers a synoptic perspective on the last thirteen decades of reactions to and interpretations of HL. I hasten to add, though, that his monograph is not simply a summary of the production, content, and reception of one of Nietzsche's early works; it is also a judicious philosophical evaluation of Nietzsche's views and arguments. It may not be the last word on HL, but the prospect of adding anything new and valuable is now daunting. (shrink)

Fictionalism plays a significant role in philosophy today, with defenses spanning mathematics, morality, ordinary objects, truth, modality, and more.1 Fictionalism in the philosophy of science is also gaining attention, due in particular to the revival of Hans Vaihinger’s work from the early twentieth century and to heightened interest in idealization in scientific practice.2 Vaihinger maintains that there is a ubiquity of fictions in science and, among other things, argues that Nietzsche supports the position. Yet, while contemporary commentators have focused on (...) fictionalism in Nietzsche’s moral philosophy, his view of fictions in science has remained largely unexamined.3 In this article, I begin...

The goal of this article is to trace the transformations in Nietzsche's early thinking that led to the ideas published in Human, All Too Human, the first book of his mature philosophy. In contrast to his early works, in which he sides with art and philosophy in criticizing the scientific culture of his time, Nietzsche, in Human, All Too Human, hails the methodology of science as a way to overcome the metaphysical delusions of philosophy, art, and religion. However, in disagreement (...) with popular scholarly view, I show that Human, All Too Human does not represent a complete break with his earlier writings, but rather a shift in emphasis. I argue that the overall project connecting Nietzsche's early thought to Human, All Too Human is, first, the attempt to come to terms with the upheavals introduced into the cultural terrain by the Socratic turn, and second, to affirm a higher culture.

There is a difficulty in understanding Nietzsche’s epistemology. It is generally accepted that he endorses the naturalized epistemological view that knowledge should be closely connected to the sciences. He also holds the evolutionary epistemological position that knowledge has developed exclusively to benefit human survival. Nietzsche’s evolutionary epistemology, however, appears to imply a debunking argument about the truth of our beliefs that seems to undermine his commitment to a naturalized epistemology. This paper argues that Nietzsche’s evolutionary epistemology does not, in fact, (...) undermine his naturalized epistemology. (shrink)

ABSTRACT There is a disagreement over how to understand Nietzsche's view of science. According to what I call the Negative View, Nietzsche thinks science should be reconceived or superseded by another discourse, such as art, because it is nihilistic. By contrast, what I call the Positive View holds that Nietzsche does not think science is nihilistic, so he denies that it should be reinterpreted or overcome. Interestingly, defenders of each position can appeal to Nietzsche's understanding of naturalism to support their (...) interpretation. I argue that Nietzsche embraces a social constructivist conception of causality that renders his naturalism incompatible with the views of naturalism attributed to him by the two dominant readings.

Nietzsche’s Anti-Darwinism. By Dirk R. Johnson (Cambridge: Cambridge University Press, 2010) In this substantial and incisive monograph, Dirk R. Johnson traces in minute detail Nietzsche’s stance towards Darwin at the various stages of his intellectually productive life. Johnson’s book is in two principal parts: Part 1 is on Nietzsche’s early Darwinism, which turned into anti-Darwinism, and Part 2 is a close reading of all three essays of Nietzsche’s Genealogy of Morals in their historical context since together they constitute “his most (...) systematic, thorough, and far-reaching analysis of the theories of Darwin and their followers” (81, 111). The author concedes that Nietzsche’s exchange with Darwin (1809–82), who was a contemporary of Nietzsche (1944–1900), is often implicit only and that he leads his explicit discussions of Darwin mostly in his unpublished notebooks. I agree with Johnson’s view that Nietzsche knew Darwin’s thought and its implications both “early and well’ (3). Johnson provides compelling evidence of the “increased personalization” of Nietzsche’s opposition to Darwinism during his last productive years after Zarathustra. For instance, Nietzsche entitled section 9,14 of Twilight of the Idols “Anti-Darwin,” and explained that “his position at this stage resulted both from his critical reappraisal of Darwin’s genealogical perspectives in the middle period and his attempt in Zarathustra to define the parameters of an affirmative, anti-metaphysical vision beyond Darwinism” (79). He argues that Zarathustra trans-values Darwinian categories such as “reason.” For him, “the work’s literary self-expression is the message,” since the superior well-being of the future higher type “can only be conjured through poetic affirmation” (48, 50).

Nietzsche has been associated with naturalism due to his arguments that morality, religion, metaphysics, and consciousness are products of natural biological organisms and ultimately natural phenomena. The subject and its mental life are only comprehensible in relation to natural desires, drives, impulses, and instincts. I argue that such typical natu-ralizing tendencies do not exhaust Nietzsche’s project, since they occur in the context of his critique of “nature” and metaphysical, speculative, and scientific naturalisms. Nie-tzsche challenges otherworldly projections of this-worldly beings, as (...) his naturalistic in-terpreters claim, but further the idolization of immanent worldly natural phenomena, in-cluding science itself. “Nature” is an idealization of natural organisms and environments in which its construction, projection, and interpretation is forgotten. Nietzsche strategical-ly uses naturalistic scientific strategies of explanation and demystification, while demys-tifying science, positivism, and naturalism for the sake of life. These do not provide either certainties or foundations for knowledge or life. Naturalism would be anti-natural if it denies of multiplicity and conflict of the forces of life, bracketing the natural and his-torical conditions of existence, and the interpretive and perspectival character of life and knowledge. The nexus of nature and history in Nietzsche is better clarified through his portrayal of the feeling of life and its intensification, attenuation, and transformation in relation to the forces and conditions of life, which encompass processes of socialization and interpretive and artistic individuation in the context of a life.

Despite his position as one of the first philosophers to write in the “post- Darwinian” world, the critique of Darwin by Friedrich Nietzsche is often ignored for a host of unsatisfactory reasons. I argue that Nietzsche’s critique of Darwin is important to the study of both Nietzsche’s and Darwin’s impact on philosophy. Further, I show that the central claims of Nietzsche’s critique have been broadly misunderstood. I then present a new reading of Nietzsche’s core criticism of Darwin. An important part (...) of Nietzsche’s response can best be understood as an aesthetic critique of Darwin, reacting to what he saw as Darwin having drained life of an essential component of objective aesthetic value. For Nietzsche, Darwin’s theory is false because it is too intellectual, because it searches for rules, regulations, and uniformity in a realm where none of these are to be found – and, moreover, where they should not be found. Such a reading goes furthest toward making Nietzsche’s criticism substantive and relevant. Finally, I attempt to relate this novel explanation of Nietzsche’s critique to topics in contemporary philosophy of biology, particularly work on the evolutionary explanation of culture. (shrink)

Güç istenci öğretisi ve bu öğretinin temel kavramları olan yorum ve perspektivizm, Türkçe Nietzsche literatüründe ihmal edilen ya da yeterince ilgilenilmemiş konulardır. Ancak, bana göre, güç istenci öğretisi ve söz konusu kavramlar olmadan, Nietzsche’nin felsefesinin anlaşılma olanağı yoktur. Güç istenci öğretisi ve bu öğretinin ortaya koyduğu güç mücadelesi, karşımıza kaotik, sürekli değişimin yaşandığı bir evren çıkarmaktadır. Bu değişimin temel dinamiği güç mücadelesidir. Bu güç mücadelesi ise, güç odaklarının bu evrene ilişkin kendi perspektiflerinden oluşturdukları yorum üzerinden gerçekleşmektedir.

L’analisi dei principali temi della filosofia di Nietzsche conduce all’individuazione della nozione di forza come elemento centrale delle sue riflessioni. Egli la incorpora ed utilizza filosoficamente, in periodi diversi, per la definizione di teorie centrali quali l’eterno ritorno, la volontà di potenza e il prospettivismo conoscitivo. L’assimilazione di questa nozione – come è stato osservato in passato – può essere riportata alla sua lettura nel 1873 della Theoria philosophiae naturalis del matematico Ruggero Boscovich. Attraverso una dettagliata analisi del materiale postumo (...) oltre che del contesto delle discussioni scientifiche dell’epoca, questo studio si propone di chiarire nella maniera più esaustiva fino a che punto il sistema di Boscovich e, più in generale, la visione dinamica del mondo in esso delineata abbiano influito sul pensiero nietzscheano, con la precisa finalità di restituire nella sua complessità il rapporto di Nietzsche con questa figura.

The aim of this study is to examine the relation between Nietzsche’s perspectivism and his doctrine of the will to power and to show that perspectivism is almost a direct and natural consequence of the doctrine of the will to power. Without exploring the doctrine, it is not possible to understand what Nietzsche’s perspectivism is and what he trying to do by proposing it as an alternative to traditional epistemology. To this aim, firstly, Nietzsche’s doctrine of the will to power (...) is explained in detail. Next, in order to provide a deeper understanding of the doctrine, its relation with Darwinism and the claims which say that it is a metaphysical principle are analyzed. Afterwards, Nietzsche’s construction of the world as becoming out of will to power is investigated. Nietzsche’s conception of interpretation as power struggle and its role in perspectivism explained. Then, how Nietzsche’s construction of the world as becoming and his concept of interpretation as power struggle emerge as perspectivism is explained. After that, in order to present the differences between Nietzsche’s perspectivism and traditional understanding of epistemology, Nietzsche’s critiques of some of the fundamental assumptions of traditional epistemology, i.e., causality, logic, and subject-object and apparent-real world distinctions, are investigated. Finally, Nietzsche’s understanding of truth based on his perspectivism is inquired. Its relation with correspondence, pragmatic and coherence theories of truth is explored to show that Nietzsche’s understanding of truth could not be comprehended through these theories. Consequently, it isclaimed that the tendency to attribute a truth theory to Nietzsche’s perspectivism, which is prevalent in the current Nietzsche studies, stems from commentator’s, consciously or unconsciously, ignoring of the relation between his perspectivism and his doctrine of the will to power.

Nietzsche offers us a critique of modern culture as threatened by a nihilistic crisis in values. Philosophy is specifically incorporated into Nietzsche's critique, resulting in the claim that modern philosophy, as well as modern culture, is nihilistic. But why should contemporary philosophers give this view credence? In this paper, I put forward some reasons to take Nietzsche's view seriously, focusing on the relationship between science and philosophy. I suggest that modern philosophy still tends to idealise science as an exemplar of (...) objectivity, particularly as this relates to judgement, even despite widespread acknowledgement that science is not value-free. I therefore argue that Nietzsche's critique is valuable in two respects: first, it calls the notion of a scientific ideal grounding objective, cross-cultural, judgement into question, and second, it facilitates a distinction between this scientific ideal and science itself.

I critically examine Nietzsche’s argument in The Will to Power that all the detailed events of the world are repeating infinite times (on account of the merely finite possible arrangements of forces that constitute the world and the inevitability with which any arrangement of force must bring about its successors). Nietzsche celebrated this recurrence because of the power of belief in it to bring about a revaluation of values focused wholly on the value of one’s endlessly repeating life. Belief in (...) recurrence would bring joy to those who had achieved excellence in this life and crush those who had not. I point out, however, that this significance of recurrence must be spoiled by the consideration that within each of the long cycles of recurrence there would have to be, as well, countless variations of this life. And I consider the issue of personal identity within such recurrences. Is it the same person or merely resembling but distinct persons in the recurrences or the variations? If it is the same person in precise recurrences, should the subjectively identical experience be thought of as really additional for that person? (shrink)
