In Metaphysics Γ, Aristotle argues against those who seem to accept contradictions. He distinguishes between the Sophists, who deny the principle of non-contradiction through arguments, and the Natural Philosophers, whose physical investigations lead to the acceptance of objective contradictions. Heraclitus’ name appears throughout the discussion. Usually, he is associated with the discussion against the Sophists. In this paper, I explore how the discussion with the Natural Philosophers may illuminate both the interpretation of Heraclitus by Aristotle and Heraclitus’ own worldview. To (...) refute the Natural Philosophers, Aristotle proposes a general reconstruction of their reasoning. Roughly, relying on sensory evidence (A1), they see that the same thing changes from one opposite to another (A2). Such a change appears to characterize a generation out of non-being, which a Natural Philosopher does not accept (A3). To solve the problem, despite their different worldviews, Natural Philosophers hint at a state in which opposites co-occur, characterizing an objective contradiction (C). Looking at the discussion in Metaphysics Γ and Heraclitus fragments, sections 1–3 show how assumptions A1, A2, and A3 easily apply to Heraclitus. The case of the conclusion is more challenging. In the case of the Pluralists, the co-existence of opposites characterizes a state in which there is no generation. Such a view does not fit Heraclitus’ mobilism. To argue that Aristotle’s argument is general enough to encompass dynamic views, I examine his problematization of accepting the change of change in Metaphysics K and Physics V. There, after re-stating several points that appear in Metaphysics Γ, Aristotle argues that accepting the becoming of another becoming leads to a state of contradiction in which the becoming is perishing. Heraclitus’ B8, cited in Nicomachean Ethics, gives evidence that, for Aristotle, Heraclitus puts a process at the origin of an opposite process. Moreover, after examining the expression ‘living the death/dying the life’ in B62, I argue that Heraclitus was aware that his worldview implied a dynamic objective contradiction. Finally, an analysis of elemental changes in B36 proves that accepting objective contradictions does not make Heraclitus’ worldview less attractive. (shrink)

We consider semantic and syntactic transformations of the concept of "the logical" in the ancient philosophy in the form of crypto-logos, para-logismos, dia-logos, and syl-logismos. We interpret Heraclitus' concept of Logos as a cryptologos through which intuitive insight (epístasthai gnóomen) reveals hidden or implicit harmony (harmoníe aphanés) in nature (phýsis) as a conceptual unity of ontic opposites (tà enantía). In Pramenides' paraconsistent concept of the identity of Being and thought, we point to para-logical hypotheses about the One that are carried (...) out through antithetical deductions of thought and which maintain the dynamics of the ontic determinations of being (ón) in the statics of the conceptual determinations of Being (tò eînai). As the beginning of the explicative granulation of ''the logical'' we consider Plato's concept of the dialectical skill (dialektikè tékhne) of dividing concepts of genus into species and sub-species that logically represent ontic opposites in problem-formulated questions. Finally Aristotle's concept of lógos as a statement-making sentence / proposition (lógos apophantikós) made explicit the Being (tò eînai), or the Being as Being (tò ón hê ón), in semantic and syntactic figures and modes of syllogistic inferences in which ontological (eînai), ontic (ón), conceptual (logikôos) and linguistic (légomenon) correspondence is shown. We conclude that with these changes in the concept of lógos, the path has been taken from the hidden or implicit Truth of the phenomena of nature and the world (pân) to explicit truthfulness of propositions as the unhiddeness (alétheia) of Being trough the semantical and syntactical visibility of the logical structures of being, thought and language in scientific knowledge based on demonstration (apoódeiksis).

The earliest mention of Melissus of Samos by name is found in the first chapter of the Hippocratic De natura hominis. In the following note, I attempt to examine what is meant by the reference Melissus’ ‘logos’ in this work and suggest, against previous accounts, including Galen’s, that it has little to do with his commitment to monism. Rather Melissus’ logos is better understood as his referring to his strategy for demonstrating such a conclusion, especially his use of a supplemental (...) argument in his fragment B8. Polybus’ concern in this first chapter is not monism as such but the claims to knowledge monists make. Melissus is a prime example of a monist who fails to grasp what he claims to know. (shrink)

In contemporary metaphysics, the Eleatic Principle (EP) is a causal criterion for reality. Articulating the EP with precision is notoriously difficult. The criterion purportedly originates in Plato’s Sophist, when the Eleatic Visitor articulates the EP at 247d-e in the famous Battle of the Gods and the Giants. There, the Visitor proposes modifying the ontologies of both the Giants (who are materialists) and the Gods (who are friends of the many forms), using a version of the EP according to which only (...) items which have the capacity to affect or to be affected are real. Recently, it has been argued that while there are some genetic connections between the EP and the views of some of the historical Eleatics (Parmenides and Zeno), the views of Melissus are generally incompatible with the EP. This raises the following question: What, exactly, is Eleatic about the Eleatic Principle? In this paper, I look to the dialectical context in which the Visitor’s appeal to the EP appears, and I propose that there are at once three relevant senses of affecting and being affected in the text: (1) tangible contact (as in the interactions between the bodies of the materialists), (2) Cambridge change (as in the form's being affected by a soul via the act of coming to know), and (3) the notion of a cause that does not itself change (as in a form’s affecting another form, a soul, or any sensible item). I argue that these have clear parallels to the metaphysics of all three main Eleatic philosophers, and that the views of Parmenides, Zeno, and Melissus are therefore compatible with the EP. This has interesting consequences for narratives about the reception of the Eleatics in Plato, the inclusion of an Eleatic Visitor as an interlocutor in the Sophist, and for the metaphysics of subsequent schools (such as the Stoics) who are widely thought to have been influenced by the EP.

What role, if any, does dialectic play in Aristotle’s epistemology in the Topics? In this paper I argue that it does play a role, but a role that is independent of endoxa. In the first section, I sketch the case for thinking that dialectic plays a distinctively epistemological role—not just a methodological role, or a merely instrumental role in getting episteme. In the second section, I consider three ways it could play that role, on two of which endoxa play at (...) least a co-starring role. But in the third section, I argue that endoxa don’t play that co-starring role, by arguing for a deflationary account of what endoxa are. For that reason, the third view emerges as the most plausible; but the third view is, I’ll suggest, Platonic. (shrink)

In here, philosophical-literate thinking on the way is mainly tried. On one side, making a philosophical analysis of Heraclitus’ fragment 60 is aimed. The different views on what Heraclitus might have meant in this article which is generally translated as the way up and the way down are one and the same are examined. On the other side, with a reading of Robert Frost’s famous poem of Road Not Taken, it has been tried whether a phenomenological interpretation of the way (...) based on passenger is possible or not. It has been researched if there is a common ground or not where this fragment and poem -which exhibit two different views on the way- have met each other. This fragment and poem has been linked together on the context of essentiality of the passenger for the way. (shrink)

The paper starts with reflections on Plato’s critique of the poets and the preference many express for Aristotle’s view of poetry. The second part of the paper takes a case study of analytic treatments of ancient philosophy, including the ancient philosopher poets, to examine the poetics of analytic philosophy, diagnosing a preference in Analytic philosophy for a clean non-poetic style of presentation, and then develops this in considering how well historians of philosophy in the Analytic tradition can accommodate the contributions (...) of philosophers who wrote in verse. The final part of the paper reviews the current enthusiasm for decoding Empedocles’ vague and poetic descriptions of the cosmic cycle into a precise scientific periodicity on the basis of the recently discovered Byzantine scholia on Aristotle. I argue that this enthusiasm speaks to a desire for definite and clear numerical values in place of poetic motifs of give and take, and that this mathematical and scientific poetic is comparable to the preferred poetic of analytic philosophy.

In my paper, I shall provide a reading of Diogenes of Apollonia such that his understanding of the metaphysics of differentiation and of individual ensoulment may constitute an ingenious answer to the problems of his time. To this extent, I will argue that Diogenes' worldview solves the difficulties of Anaxagoras' metaphysics and successfully integrates mentality in a causally closed conception of nature. Finally, I will suggest that a Diogenes-inspired approach might be relevant to treat some pressing concerns in the contemporary (...) philosophy of mind – thus demonstrating how his production might offer some interesting solutions for the problems of our time too.

In this paper, I investigate how Xenophanes was ‘eleaticised’, i.e. attributed theses and arguments that belong to Parmenides and Melissus. I examine texts of Plato, Aristotle and Theophrastus in order to determine if they considered Xenophanes as a philosopher and a monist. I show that neither Plato nor Aristotle regarded him as a philosopher, but rather as a pantheist poet who claimed, in a vague way, that everything is one. But Theophrastus interpreted too literally Aristotle’s claims and was the first (...) to make Xenophanes a proper monist philosopher. (shrink)

I offer an examination of a core element in the reflectiveness of Heraclitus’ thought, namely, his rebuke of polymathy . In doing so, I provide a response to a recent claim that Heraclitus should not be considered to be a philosopher, by attending to his paradigmatically philosophical traits. Regarding Heraclitus’ attitude to that naïve form of ‘wisdom’, i.e., polymathy, I argue that he does not advise avoiding experience of many things, rather, he advises rejecting experience of things as merely many (...) independent things in their manifoldness , and, instead, to understand their unity and thereby to unify our knowledge of them.

Parmenides and Melissus employ different deductive styles for their different kinds of argumentation. The former’s poem flows in an interesting sequence of passages: contents foreword, methodological premises, krisis, conclusions and corollaries. The latter, however, organizes an extensive process of deduction to show the characteristics of what is. In both cases, the strength of their argument rests on their deductive form, on the syntactical level of their texts: the formal structure of their reasonings help to identify the features and logical intersections (...) of their thoughts. On the one hand, Parmenides uses modal reasoning, enforcing the employment of the principle of the excluded middle. On the other hand, Melissus radicalizes the use of modal reasoning and employs counterfactual statements in order to develop his doctrine of what is. Despite their differences, both deserve a place in the Stone Age of logic and theory of argumentation due to their common ambition to demonstrate what is. (shrink)

Anaximenes is usually considered to be a material monist recognizing transparent atmospheric air as a principle (ἀρχή). In the cosmogonic explanation of the origin of the earth and the heavenly bodies, the Greek term ἀήρ turns out to mean rather ‘opaque damp mist’. However, Not only does it accord with archaic usage, but also with how it was used in his mentor, Anaximander. Yet, in cosmology ἀήρ means ‘air’ serving as stuff on which the earth and the heavenly bodies float. (...) Hence, in keeping with contemporary usage, Anaximenes recognised two kinds of ἀήρ, distinguishing them functionally. Whereas mist is conceived of as a generating substance, air functions only as carrying stuff. (shrink)

At Phaedo 86b7–c2 Simmias puts forward the theory that the soul is the attunement of bodily elements. Many scholars have claimed that this theory originates in the Pythagoreans, especially Philolaus. The claim is largely based on their reading of the Phaedo, since we have scarce doxographical evidence. In this paper I show that the dialogue in question does not constitute any evidence for the Pythagorean origin of Simmias’ attunement theory, and that it rather represents the theory as stemming from a (...) materialistic world view that had become widespread among people at that time. I also pursue the question how and why, then, the attunement theory was able to attract many people, by examining its relation to Socrates’ affinity argument. (shrink)

This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, and the teleology of emerging things. He shows that Aristotle’s distinctive ontological claim—that being is inescapably diverse in kind—is anchored in his argument for the existence of change. -/- Aristotle may be the only thinker to have given a noncircular definition of change. When (...) he gave this definition, arguing that change is real was a losing proposition. To show that it exists, he had to rework the way philosophers understood reality. His groundbreaking analysis of change has long been interpreted through a Platonist lens, however, in which being is conceived as unchanging. Offering a comprehensive reexamination of the relationship between change and being in Aristotle, Sentesy makes an important contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.

According to quality theories of love, love is fitting by virtue of properties of the loved person. Despite their immediate plausibility, quality theories have met with many objections. Here I focus on two that strike at the heart of what makes the quality theory an appealing account of love, specifically, the theory’s ability to accommodate the fact that loving someone is a way of valuing them for who they are. The fungibility objection and the problem of love’s object maintain that (...) if a person is loved on the basis of their qualities, they are not valued in the right kind of way. I propose a new kind of quality theory which both answers these objections and is independently well-motivated. Specifically, I argue that to love a person as a whole, one must value them as an organic unity. (shrink)

In his Encomium of Helen, Gorgias provides us with a variety of arguments in order to show that Helen was not to be held accountable for having eloped with Paris. The main thesis advanced in this article is that these arguments, despite their apparent diversity, are given a unitary structure by the concept of force, and by the analogy that Gorgias estalishes between persuasion, the emotions, and sense-perception on the one hand, and this concept on the other. If this argument (...) is successful, it shows that practically none of our actions are such that we are morally responsible for them. I discuss the cogency of this argument in connection with Aristotle’s objections to it. (shrink)

Beginning the nineteenth-century and continuing down to the present, many authors writing on the history of geology and paleontology have attributed the theory that fossils were inorganic formations produced within the earth, rather than by the deposition of living organisms, to the ancient Greeks and Romans. Some have even gone so far as to claim this was the consensus view in the classical period up through the Middle Ages. In fact, such a notion was entirely foreign to ancient and medieval (...) thought and only appeared within the manifold of ‘Renaissance episteme,’ the characteristics of which have often been projected backwards by some historians onto earlier periods. This paper endeavors to correct this error, explain the development of the Renaissance view, describe certain ancient precedents thereof, and trace the history of the misinterpretation in the literature. -/- .

This paper focuses on Anaximander's pinax, the first map according to Western tradition. Its aim is to demonstrate that it is only after the realization of the pinax that it was possible to distinguish between Being and beings in a Heideggerian sense, that is to pose the question of the ontological difference. Consequently, all the history of Western thought is nothing but the history of the raising of cartographical representation, and of reason here embodied, from the dark rigidity of death (...) to the rarefied splendours of Pure Reason.

The essay revisits the puzzle of the ‘passage’ of time in relation to EPR-type measurements and asks what philosophical consequences can be drawn from them. Some argue that the lack of invariance of temporal order in the measurement of a space-like related EPR pair, under relativistic motion, casts serious doubts on the ‘reality’ of the lapse of time. Others argue thatcertain features of quantum mechanics establisha tensed theory of time – understood here as Possibilism or the growing block universe. The (...) paper analyzes the employment of frame-invariant entropic clocks in a relativistic setting and argues that tenselessness does not imply timelessness. But this conclusion does not support a tensed theory of time, which requires a preferred foliation. It is argued that the only reliable inference from the EPR example and the use of entropic clocks is an inference not just to a Leibnizian order of the succession of events but a frame-invariant order according to some selected clocks.

This paper is a brief discussion of the famous 'Third Man Argument' as it appears in Plato's dialogue Parmenides . I mention, criticise and refine the most influential analytic approach to the argument; show that the actual conclusion of the argument is different from the one attributed to it by the majority of scholars; and elaborate two responses to the argument, both of which shed interesting light on the Theory of Forms.

In Aristotle’s On the Soul he considers and refutes two versions of the harmonia theory of the soul’s relation to the body. According to the harmonia theory, the soul is to the body what the tuning of a musical instrument is to its material parts. Though he believes himself to have entirely dismissed the view, he has not. I argue that Aristotle’s hylomorphic account is, in fact, an instance of the harmonia theory.

This study focuses on the origin of life as presented in the thought of Anaximander of Miletus but also points to some parallel motifs found in much later conceptions of both the pre-Darwinian German romantic science and post-Darwinian biology. According to Anaximander, life originated in the moisture associated with earth (mud). This moist environment hosted the first living creatures that later populated the dry land. In these descriptions, one can trace the earliest hints of the notion of environmental adaptation. The (...) origin of humans was seen as connected in some way with fish: ancient humans were supposed to have developed inside fish-like animals. Anaximander took into account changes in the development of living creatures (adaptations) and speculated on the origins of humans. Similar ideas are found also in the writings of much later, eighteenth and nineteenth century authors who were close to the tradition of German romantic science. We do not argue that these later concepts are in any way directly linked with those of the pre-Socratics, but they show surprising parallels in, e.g., the hypothesis that life originated in a moist environment or the supposition that human developed from fish-like ancestors. These transformations are seen as a consequence of timeless logic rather than as evolution in historical terms. Despite the accent on the origin of living things, both Anaximander and the later Naturphilosophen lack in their notions the element most characteristic of Darwin’s thought, that is, the emphasis on historicity and uniqueness of all that comes into being.

Humoralism, the view that the human body is composed of a limited number of elementary fluids, is one of the most characteristic aspects of ancient medicine. The psychological dimension of humoral theory in the ancient world has thus far received a relatively small amount of scholarly attention. Medical psychology in the ancient world can only be correctly understood by relating it to psychological thought in other fields, such as ethics and rhetoric. The concept that ties these various domains together is (...) character (êthos), which involves a view of human beings focused on clearly distinguishable psychological types that can be recognized on the basis of external signs. Psychological ideas based on humoral theory remained influential well into the early modern period. Yet, in 17th-century medicine and philosophy, humoral physiology and psychology started to lose ground to other theoretical perspectives on the mind and its relation to the body. This decline of humoralist medical psychology can be related to a broader reorientation of psychological thought in which the traditional concept of character lost its central position. Instead of the focus on types and stable character traits, a perspective emerged that was primarily concerned with individuality and transient passions. (shrink)

In On Generation and Corruption, Aristotle rejects the very possibility of such a thing as Anaximander’s apeiron. Characterized as a kind of intermediate stuff, the apeiron turns out to consist of contraries and as such is impossible. Commentators have rightly noted this point and some have also indicated that Aristotle offers an argument of sorts for his negative estimate. However, the argument has received scant attention, and it is fair to say that it remains unclear exactly why Aristotle rejects Anaximander’s (...) intermediate stuff. Indeed, it is unclear how Aristotle’s argument is supposed to run in the first place. This paper offers a reconstruction of Aristotle’s argument for the impossibility of the apeiron, and on this basis offers to explain Aristotle’s grounds for rejecting Anaximander’s intermediate stuff. This is especially called for in light of the fact that Aristotle himself thinks that there can be intermediate stuffs. Finally, some attention is given to the parallel between the apeiron and Aristotle’s prime matter. (shrink)

In Physics VI.9 Aristotle addresses Zeno's four paradoxes of motion and amongst them the arrow paradox. In his brief remarks on the paradox, Aristotle suggests what he takes to be a solution to the paradox.In two famous papers, both called 'A note on Zeno's arrow', Gregory Vlastos and Jonathan Lear each suggest an interpretation of Aristotle's proposed solution to the arrow paradox. In this paper, I argue that these two interpretations are unsatisfactory, and suggest an alternative interpretation. In particular, I (...) claim that what seems on the face of it to be Aristotle's solution to the paradox raises two puzzles to which my interpretation, as opposed to Lear's and Vlastos's, provides an adequate response.

Already in ancient philosophy, there was a transition from the implicit and hidden action of the Logical ( lógos) in nature ( phýsis) to the scientific and explicit expression of the logical structures of thought, action, the world and language. Heraclitus' heno-logic with Logos as hidden implicit principle of homologization of opposites ( tà enantía) in nature differs from Parmenides' paraconsistent logic developed in a hypothetical hemidyalectics given in the formula ''All is One'' ( hén pánta eînai). Plato's concept of (...) dia-logic (dialektikè téchne ) with a new concept of Logos as the one genus of beings ( hén tí génon toôn ontoôn) in which the word not-Being (negation) got its place enabled production of dyadic logical structure by the granulation of genera into opposite species and sub-species that it contains. Aristotle's concept of triadic-logic as syl-logistics ( syllogismós) and demonstrative science (epistéme apodeiktikê ) give a new approach by new granulation of the concept of Logos into triadic logical structure: (1) the structure of being (substratum-attributes relation), (2) the structure of thought (substance-second substances relation), and (3) the structure of propositions (subject-predicate relation). Plato's dialectic and Aristotle's syllogistic both deconstructed the implicit ontological unity of the world (pan, kosmos, sphairos ) given through the concept of Logos in Pre-Socratic philosophy in order to make that unity in explicit form given by the logical and semantical structures of the propositions about the world, about the thought and about the language. The hidden implicit of the nature, which had to be known intuitively, was transformed into unhidden explicit inferential logical structures given in the semantics and pragmatics of scientific demonstration.

There is a long and successful scholarly tradition of commenting on Nietzsche’s deep affinity for the philosophy of Heraclitus. But scholars remain puzzled as to why he suggested at the end of his career, in Ecce Homo, that the doctrine he valued most, the eternal recurrence of the same, might also have been taught by Heraclitus. This essay aims to answer this question through a close examination of Nietzsche’s allusions to Heraclitus in his first published mention of eternal recurrence in (...) The Joyful Science and in a related set of notes from the period when he was formulating and defending his doctrine of eternal recurrence while writing Thus Spoke Zarathustra. The key to answering this question, it is argued, is that Nietzsche came to believe that the doctrine of eternal recurrence, when properly understood as requiring identical repetition, has to presuppose a Heraclitean reality of eternal, absolute, and universal flux.

Writers on organisational change often refer to the cosmology of Heraclitus in their work. Some use these references to support arguments for the constancy and universality of organisational change and the consignment to history of organisational continuity and stability. These writers misunderstand the scope of what Heraclitus said. Other writers focus exclusively on the idea that originated with Heraclitus that the universe is composed of processes and not of things. This idea, which has been particularly associated with Heraclitus’s thought from (...) the time of Plato, does indeed provide a rich source of insights into organisational analysis, not least the current trends towards giving proper attention to processual studies of organisational change. Yet there is some uncertainty as to whether Heraclitus actually said that the universe was composed exclusively of processes rather than things, and even if that was what he thought, he intended his ideas on flux to be understood not in isolation but in the context of other aspects of his cosmology. Writers on organisational change seldom make reference to this wider context. Heraclitus was a rational but also a religious thinker. A central element in his thought was the notion of divine Justice, which to a Greek of his era meant the order of the universe. Remote as his Olympian theology may seem today, it sets a crucial and entirely rational context for understanding his ideas about flux. It means that ideas about continuity and stability were quite as important in Heraclitus’s cosmology as his more commonly quoted ideas about change. This paper sets out an overview of Heraclitus’s philosophy, insofar as it appears to have potential relevance to organisational analysis, and discusses how far it supports or contradicts the ideas that organisational change scholars have drawn from it.

In this paper, I defend a theory of local temporality, sometimes referred to as a point-present theory. This theory has the great advantage that it allows for the possibility of an open future without requiring any alterations to our standard understanding of special relativity. Such theories, however, have regularly been rejected out of hand as metaphysically incoherent. After surveying the debate, I argue that such a transformation of temporal concepts (i) is suggested by the indexical semantics of tense in a (...) relativistic universe, (ii) when properly understood easily withstands the usual accusations of metaphysical incoherence and (iii) leads naturally to a meta-philosophical position from which we can understand and escape the increasing sterility of debates between radical Parmenideans and radical Heracliteans in the philosophy of time.

Traditionally one main emphasis of the quantum mechanical measurement theory is on the question how the pure state of the compound system 'measured system + measuring apparatus' is transformed into the 'mixture' of all possible results of that measurement, weighted with their probability: the so-called “disappearance of the interference terms”.

The main purpose of this paper is to characterize and compare two forms any relativist thesis can take: indexical relativism and genuine relativism. Indexical relativists claim that the implicit indexicality of certain sentences is the only source of relativity. Genuine relativists, by contrast, claim that there is relativity not just at the level of sentences, but also at propositional level. After characterizing each of the two forms and discussing their difficulties, I argue that the difference between the two is significant.

According to current interpretations of Parmenides, he either embraces a token-monism of things, or a type-monism of the nature of each kind of thing, or a generous monism, accepting a token-monism of things of a specific type, necessary being.

We effect this by arguing that Parmenides champions a metaphysically refined form of material monism, a type-monism of things; that light and night are allomorphs of (...) what-is ; and that the key features of what-is are entailed by the theory of material monism.

Using the results of the latest neurophysiological research on colour, the article rejects outright physicalism and dispositionalism as appropriate approaches to solving the problem of colour realism. Physicalism sees colour as a real property of objects, i.e. the reflectance profile, while dispositionalism takes subjects, objects and light as necessary elements for colour production. First, it briefly outlines the historical development of the theory of colour, pointing towards dispositionalism which, in some sense, considers colour as a real entity of the world, (...) and then introduces the problem of colour realism, focusing on objections to physicalism as well as dispositionalism. After delineating the neurophysiological mechanisms underlying the visual experience of colour, and with the help of the concrete results of practical neurophysiological experiments, the article points to why the physicalist and any dispositionalist theories of colour in the light of a new physiological objection do not present credible views on the nature of colour.

Sextus’ interpretation of Xenophanes’ scepticism in M 7.49–52 is often cited but has never been subject to detailed analysis. Such analysis reveals that Sextus’ interpretation raises far more complex problems than has been recognised. Scholars invariably assume one of two ways of construing his account of Xenophanes B34, without observing that the choice between these two alternatives poses an interpretive dilemma. Some scholars take it that Sextus ascribes to Xenophanes the view that one may have knowledge without knowing that one (...) has knowledge. Others take it that he ascribes to Xenophanes the view that one may have true belief without knowing that one has true belief. A close examination of Sextus’ paraphrase exposes a crucial but overlooked complication. Sextus elides Xenophanes’ pivotal distinction between knowing “the clear and certain” and believing “what has been fulfilled” . He eliminates altogether tetelesmenon from his analysis of B34, and expands the role of to saphes. I demonstrate that, as a result, Xenophanes B34, as interpreted by Sextus, does not consistently and straightforwardly express either view or view . Sextus, I argue, in fact develops a fundamentally incoherent interpretation of Xenophanes B34. On Sextus’ interpretation, Xenophanes justifies the proposition “No human knows” by arguing that, even if a human does, in fact, know, he does not know that he knows. Finally, I argue that Sextus’ incoherent account reflects not unthinking negligence, but a sophisticated if ultimately doomed attempt to interpret the logical structure of Xenophanes B34 in line with later models of second-order scepticism.
