It is now a commonplace that Aristotle and Theophrastus systematically misunderstood Heraclitus in interpreting fire as an ἀρχή of the kind posited by the Milesians. While air in the thought of Anaxamines and the ἄπειρον in the thought of Anaximander can be considered to play the role of the Aristotelian material substrate without too much distortion, this is not so for fire in the thought of Heraclitus. As Cherniss has indicated, while a substrate of the kind posited by the Milesians (...) is a permanent being underlying change, Heraclitean fire is change itself. (shrink)

The recent discovery of the medullary circuit driving “hunger responses” – reduced thermogenesis and promoted feeding – has greatly expanded our knowledge on the central neural networks for energy homeostasis. However, how hypothalamic hunger and satiety signals generated under fasted and fed conditions, respectively, control the medullary autonomic and somatic motor mechanisms remains unknown. Here, in reviewing this field, we propose two hypothalamomedullary neural pathways for hunger and satiety signaling. To trigger hunger signaling, neuropeptide Y activates a group (...) of neurons in the paraventricular hypothalamic nucleus (PVH), which then stimulate an excitatory pathway to the medullary circuit to drive the hunger responses. In contrast, melanocortin‐mediated satiety signaling activates a distinct group of PVH neurons, which then stimulate a putatively inhibitory pathway to the medullary circuit to counteract the hunger signaling. The medullary circuit likely contains inhibitory and excitatory premotor neurons whose alternate phasic activation generates the coordinated masticatory motor rhythms to promote feeding. (shrink)

Heraclitean flux plays a large role in Plato 's « Theaetetus » and « Cratylus ». Yet Heraclitus himself did not hold the same conception of flux. The question of how the two thinkers differ, and why Plato treats Heraclitus as he does, is significant because the notion of flux has figured in subsequent philosophical conceptions of the persistence of identity through change. Comparison of Heraclitus, frr. B 12 and B 125 DK reveals that flux is not motion simply, (...) but motion productive of stability ; the unity of stability and flux is the « unapparent connection » that it is Heraclitus ' mission to reveal. Analysis of Tht. 179 C-181 B and Cra. 402 A 3-8 and 411 B-C shows neither any exegesis of Heraclitus ' words, nor any evidence that Plato has in mind any historical Heracliteans. The playful way in which Plato handles Heracliteanism, with comic and hyperbolic imagery, suggests that his audience would have recognized Heraclitean flux as a familiar theory from the context of contemporary oral dialectic.

This essay offers an original interpretation and defense of the doctrine of flux, as it is presented in Plato’s Theaetetus. The methodology of the paper’s analysis is in the style of rational reconstruction, and it is highly analytic in scope, in the sense that I will focus on the text itself, and only on certain parts of it too, while ignoring the rest of Plato’s extensive corpus, and without worrying about whether, how, and to what extent the interpretation of the (...) view coheres well with the other elements of the secret doctrine view discussed in the dialogue, as well. In the first part of the essay, I’ll offer my interpretation of the doctrine. Then, in the second part of the essay, I’ll examine two potential criticisms of the doctrine, including Socrates’s infamous linguistic paradox, and show how my interpretation of Heraclitean flux metaphysics is able to circumvent both.

Kant makes a much-unexpected confession in a much-unexpected place. In the Criticism of the third paralogism of transcendental psychology of the first Critique Kant accepts the irrefutability of the Heraclitean notion of universal becoming or the transitory nature of all things, admitting the impossibility of positing a totally persistent and self-conscious subject. The major Heraclitean doctrine of panta rhei makes it impossible to conduct philosophical inquiry by assuming a self-conscious subject or “I,” which would potentially be in constant (...) motion like other thoughts. For it rules out the possibility of completely detached reasoning which necessitates an unchanging state of mind. In this paper, Kaplama uses panta rhei to critically examine the philosophical shortcomings and contradictions of Kantian and Enlightenment ethics. In his examination, he specifically focuses on the teleological nature of Kant’s principle of freedom and ideal of moral autonomy which have dominated the Enlightenment thought. By doing so, he argues that it is essentially inaccurate to posit Überlegenheit (the state of being superior to nature) as the foundation of philosophical inquiry mainly because this would contradict the Enlightenment’s claim to constitute a rupture from classic and medieval metaphysics and would render Enlightenment a mere extension of Christian metaphysics. As in Christianity, Überlegenheit presupposes two separate realms, the actual (contingent) and ideal (pure) realms of thought and assumes that the transcendence commences from the level of the late metaphysical/teleological construction of the ‘subject’ who is completely persistent, self-conscious and immune to change. He then substantiates these points with reference to the philosophical roots of ethnic prejudice displayed by the post-Enlightenment colonialists and the missionaries in Fiji and the Pacific. This brief critical examination of the post-Enlightenment ethnocentrism will be conducted under the following three points: a) On the Enlightenment’s teleological and universalistic understanding of humanity and the concept of progress versus the Fijian concepts of the continuity of life, regeneration, and reproduction b) On the Enlightenment’s ideal of the free-willing and independent individual subject versus the Fijian ideas of 'the cord', reciprocity, and vanua, and c) On the Enlightenment’s (and Christianity’s) strict dualism between physics and metaphysics, nature and human mind, body and soul versus the Fijian bio-centrism, the sanctity of vanua and the cosmological concept of mana.

‘Cataracts’ in Stevens’ poems are falling waters—here a river flowing near a mountain. The ‘apostrophe that was not spoken’ may be an address that was not made, perhaps an unspoken affirmation of nature’s beauty. And the river that ‘is never the same twice’ can only be the flowing river Plato claimed Heraclitus used as a simile for all existing things: ‘Heraclitus says somewhere that everything gives way and nothing remains, and likening existing things to the flow of a river, he (...) says that you cannot step twice into the same river’ (Cratylus, 402a). There are five respects in which ‘This Solitude of Cataracts’ displays affinities with Heraclitean ideas: its use of a river as a simile for human experience, the poet’s desire to express the real nature of things, rivers and mountains as polar opposites, the exploitation of ambiguities, and the use of particulars as emblematic of general truths.

This paper is devoted to the analysis of Plotinus’ citation of the Heraclitean saying B113 DK in the second treatise On the Presence of Being (VI 5 [23]). I shall argue that the use which the author of the Enneads makes of this fragment has been hitherto misunderstood by scholars and that, for this reason, the significance of the passage and its role within Plotinus’ argument have been missed. Close attention will be paid to the tool through which Plotinus (...) conveys his own reading of Heraclitus’ tenet, i.e. etymology, and to the passages in which he both lays down and puts into practice the programmatic guidelines for his interpretation of the Presocratic. In addition, I shall interpret Plotinus’ recourse to a wordplay which is, in character, quite Heraclitean as a proof of the importance of his philosophical engagement with the Obscure. (shrink)

Gerard Manley Hopkins is best remembered for his celebratory 'nature sonnets'— 'Pied Beauty', 'God's Grandeur', and 'The Windhover'. Less than a year before his death, however, Hopkins drew on ideas associated with the ancient Greek thinker Heraclitus of Ephesus to express a darker view of nature. In 'That Nature is a Heraclitean Fire and of the Comfort of the Resurrection’ Hopkins offers a vision of nature and human existence marked by dissolution and destruction. But the poet rejects that apocalyptic (...) vision in favor of the Christian promise of salvation: ‘in a flash, at a trumpet crash/ I am all at once what Christ is…’ In articulating his dark vision of nature Hopkins followed Heraclitus’ fragment B 30: ‘this cosmos…a fire.’ However, Heraclitus’ cosmos ‘always was, is, and will be, an ever-living fire, kindled in measures and extinguished in measures.’ It was not, therefore, the one-way descent to destruction Hopkins described.

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.

This article applies and defends an intertextual approach to Heraclitus B51 DK, the ‘bow-lyre fragment’. It argues that the fragment alludes to the climactic scene of the Odyssey in which the hero strings the bow and is likened to an expert lyre-player. It then explores some implications of this point for our understanding of the significance of the fragment, of the sixth-century reception of the Odyssey and of Parmenides’ reception of Heraclitus.

Previous chapter Nietzsche wanted to complement The Birth of Tragedy with an essay on The Philosophy in the Tragic Age of the Greeks. This book was never completed but various fragments still remain: a few pages long piece, Der letzte Philosoph.

In ‘Hoi Rheontes’ (‘The Flowing Ones’), Alfred Lord Tennyson adopted the Heraclitean simile of the flowing river in support of philosophical relativism: (1) all things are changing all the time; therefore (2) nothing is, but is only in the process of appearing to be in some way; therefore (3) all beliefs are true. But the relativist doctrine refutes itself: it can only be true relatively to those who assert it. In his ‘In May’ the American poet Michael Collier rejected (...) what he regarded as Tennyson’s endorsement of skepticism concerning the senses. According to Collier, Heraclitus sought to show how there is pleasure to be found in sense experience. In his ‘Gift of Heraclitus’ the prize-winning Mexican poet José Emilio Pacheco drew on a dozen or so Heraclitean ideas to fashion an existential reflection on the human condition. Unlike natural substances, human reality is characterized by reflection, change, and unfulfilled desire. (shrink)

This piece contrasts two ontological views of perceptual experience: on the one hand, Experiential Heracliteanism, a view according to which the intuitively dynamic character of experience should be described – and probably accounted for – in irreducibly dynamic terms; and, on the other, Experiential non‐Heracliteanism, a stance according to which perceptual experience may at least be described – if not explained – in terms of nondynamic constituents. I specially strive (1) to frame both proposals against the backdrop of a venerable (...) Heraclitean metaphor and (2) to highlight the virtues of Experiential non‐Heracliteanism against its currently sexier Heraclitean counterpart. (shrink)

Many of the poems of Louis MacNeice display a knowledge of the philosophical theories he studied during his undergraduate years in Oxford. In his ‘Variation on Heraclitus’ and in several other poems, MacNeice alludes to the ‘doctrine of flux’ Plato attributed to the Greek thinker Heraclitus of Ephesus. In ‘Plurality’, his most extended exploration of the conflict between the life-affirming doctrine of flux and a life-suppressing monism, MacNeice embraces the reality of change and rejects the monism he credits to the (...) philosopher Parmenides of Elea: ‘World is not like that, world is full of blind/ Gulfs across the flat, jags against the mind/ Swollen or diminished according to the dice/ Foaming, never finished, never the same twice.’ Although his understanding of the teachings of Heraclitus and Parmenides was controversial, it provided MacNeice with a framework within which to reflect on the conditions essential to living a free and productive life.

"Heidegger" and "comedy" are words that one seldom finds conjoined. However, in his 1943 Summer Freiburg lecture course entitled " Der Anfang des abendländischen Denkens. Heraklit ," the word " komisch " occurs significantly, it is regarded as superior to " das Tragische ," and thus can open up a new vista onto Heideggerian thought. In this paper, I discuss Heidegger's interpretive translation of Heraclitus' Fragment 123: Φυσιζ κρυπτ∊σθαι φιλ∊ι. I attempt to show how Heidegger distinguishes his translation and interpretation (...) from other great thinkers and other ways of thought, and how this distinction ultimately unfolds into that unlikeliest and untimeliest of beings, a uniquely comic Heidegger.

In ‘Burnt Norton’, the first of his ‘four quartets’, Eliot selected two Heraclitus’ fragments as epigraphs. In quoting fragment B 60 (‘the way up and the way down are one and the same’) he was reminding his readers that entrance into a spiritual life calls for both engagement and withdrawal, for both descending and ascending. And in quoting B 2 he reaffirmed Heraclitus’ conviction that most people fail to recognize the truth even when it is directly presented to them. In (...) his later Cocktail Party Eliot revisited these themes by converting a depiction of a failed social gathering into an exploration of forms of authenticity. He also exploited the dual nature of the Heraclitean daimôn—as external overseer and as the soul which lies within each person—to transform an account of a gathering of friends and strangers into an extended reflection on the conflicts lying within each human soul.

This inquiry aims to highlight the philosophical perspective of Aristotle’s “business” priority of the organization over the individual in combination with Heraclitus’ flux theory and the unity of opposites to alternatively approach organizational resilience. While current literature on organizational resilience argues that disorganization and gradual decaying are probable but not certain, they can be predicted and managed. In contrast, the combined analysis of Aristotelian and Heraclitean philosophical theories points out that organizational disorganization and the fluctuation of resilience are a (...) certainty and not a probability, constituting an automation embedded in a circular, repeatable pattern for organizations and businesses. In this project, organizational and entrepreneurial scientific realism meets with the philosophical synthesis of Heraclitus’ and Aristotle’s thought on organizational resilience. The intended outcome of this “encounter” is to contribute an applicable perceptual “intellectual tool” that will foster a deeper understanding of resilience, organizationally and individually.

In this note I address two issues in Susan Edwards-McKie’s recent paper “The Cosmic Fragment: Härte des Logischen Zwangs und Unendliche Möglichkeit. Nachlass discoveries and Wittgenstein’s conception of generality and the infinite”. The first has to do with a “von Wright error” that Edwards- McKie found and that I show to have been ultimately corrected by von Wright. The second has to do with her interpretation of Wittgenstein’s reaction to Heraclitus’ idea that “everything flows”, one I interpret as purely grammatical (...) and not as a substantial position in favour or against Heracliteanism, nor even as a third stance between this and Parmenideanism, as Edwards-McKie interestingly suggests.

In this paper, I explore a prominent question of Hericlitean scholarship: how is change possible? Karl Popper and G. S. Kirk tackle this same question. Kirk asserts that Heraclitus believed that change is present on a macrocosmic level and that all change is regulated by the cosmic principle logos. Popper, on the other hand, claims Heraclitus believed that change is microcosmic and rejected that all change is regulated by logos. I argue for a combination of aspects from each of their (...) claims and conclude that change is present both microcosmically and macrocosmically and that all change is governed by logos . (shrink)

Microbes in the gastrointestinal tract are under selective pressure to manipulate host eating behavior to increase their fitness, sometimes at the expense of host fitness. Microbes may do this through two potential strategies: (i) generating cravings for foods that they specialize on or foods that suppress their competitors, or (ii) inducing dysphoria until we eat foods that enhance their fitness. We review several potential mechanisms for microbial control over eating behavior including microbial influence on reward and satiety pathways, production (...) of toxins that alter mood, changes to receptors including taste receptors, and hijacking of the vagus nerve, the neural axis between the gut and the brain. We also review the evidence for alternative explanations for cravings and unhealthy eating behavior. Because microbiota are easily manipulatable by prebiotics, probiotics, antibiotics, fecal transplants, and dietary changes, altering our microbiota offers a tractable approach to otherwise intractable problems of obesity and unhealthy eating.

Why is there a new explosion of interest in authentic ethnic foods and exotic cooking shows, where macho chefs promote sensual adventures in the kitchen? Why do we watch TV ads that promise more sex if we serve the right breakfast cereal? Why is the hunger strike such a potent political tool? Food inevitably engages questions of sensuality and power, of our connections to our bodies and to our world. Carnal Appetites brilliantly uses the lens of food and eating to (...) ask how we eat into culture, eat into identities, indeed eat into ourselves. Drawing on interviews, theory, and her own war with anorexia, Probyn argues that food is replacing sex in our imagination and experience of bodily pleasure. Our culinary cravings and habits express the turmoil in gender roles, in families, and even in the world economy, where famine coexists with plenty. Probyn explores these dark interconnections to forge a new visceral ethics rooted in the language of hunger and satiety, disgust and pleasure, gluttonyand restraint. From the fat pride movement and diet fads to genetically altered grain and colonial cannibalism, Carnal Appetites looks at what we eat to tell us who we are. (shrink)

Several forms of dietary learning have been identified in humans. These include flavor–flavor learning, flavor–postingestive learning , and learned satiety. Generally, learning is thought to occur in the absence of contingency or demand awareness. However, a review of the literature suggests that this conclusion may be premature because measures of awareness lack the rigor that is found in studies of other kinds of human learning. If associations do configure outside awareness then this should be regarded as a rare instance (...) of automatic learning. Conversely, if awareness is important, then successful learning may be governed by an individual’s beliefs and predilection to attend to stimulus relationships. For researchers of dietary learning this could be critical because it might explain why learning paradigms have a reputation for being unreliable. Since most food preferences are learned, asking questions about awareness can also tell us something fundamental about everyday dietary control. (shrink)

Recent literature highlights that the use of smartphones during meals increases the number of calories ingested in young people. Although the distraction interferes with physiological signals of hunger and satiety, a social facilitation effect has also been suggested. Cognition is a pivotal component in regulating food intake, and activities requiring high perceptual demands should be discouraged during meals.

In two experimental studies we explore to what extent the general effects of positive and negative framing also apply to positive and negative persuasion. Our results reveal that negative persuasion induces substantially higher levels of skepticism and awareness of being subjected to a persuasion attempt. Furthermore, we demonstrate that in positive persuasion, more claims lead to stronger persuasion, while in negative persuasion, the numerosity of claims carries no significant effect. We interpret this finding along the lines of a satiety-model (...) of persuasion. Finally, using diluted, or low strength claims in a persuasion attempt, we reveal a significant interaction between dispositional reactance and dilution of claims on persuasion knowledge. The interaction states that diluted claims increase the awareness of being subjected to a persuasion attempt, but only for those with a high dispositional level of reactance. (shrink)

Stoic concepts of ekpyrosis and diacosmesis are examined in light of later Platonic, Aristotelian and Epicurean critiques of Stoic determinism. Questions emerge out of this debate centered on the problem of evil. A series of theodicies are proposed ending in a later Stoic interpretation of the cosmic cycle that equates each phase of the cosmic cycle with an ethical one allegorized as periods of Satiety and Dearth.

Heraclitus was not a Hegelian logician. Rather he considered the lógos as a cyclical law of the Sky, which is ordered in three concentric circles of increasing size. Every circle has its own cycle: night/day, winter/summer, poverty/satiety.
