    The laughing philosopher, Democritus, and his counterpart, the weeping philosopher, Heraclitus, have had a pervasive influence on western philosophy and art in part because of the murky legend which juxtaposes them. In this chapter I enquire into the causes of their weeping and laughter, and speculate about how these reactions came to be attributed to the historical Heraclitus and Democritus, both of whom flourished in the fifth century BCE. The chapter is divided into three parts: in part 1, I …Read more

    I attribute an entire new chapter of material to the reconstruction of Aristotle’s Protrepticus: the large and continuous excerpts contained in Iamblichus’ On the Common Mathematical Sciences chapter xxvii. This material has never been attributed to the lost work before and expands the evidence base of the work by about 75 lines of Greek. I further show that the famous protreptic to the study of plants and animals in Aristotle’s On the Parts of Animals I.5 is a text re-use and adaptation, on Ari…Read more

    We offer a survey of the Aristotle Corpus (the Organon or logical works; the physics or natural works, the Metaphysics, the practical works, and the productive works (Rhetoric and Poetics) and discuss “protreptic aspects” pertinent to each, including: (1) direct discussion of protreptic rhetoric by Aristotle in the Rhetoric and Topics; (2) indirect employment of protreptic rhetoric in other works (such as On the Soul, Parva Naturalia, On the Parts of Animals), and (3) text re-uses or parallels t…Read more

    Aristotle theorized about exhortative (“protreptic”) rhetoric in his treatise on the Art of Rhetoric, and he also authored a popular work (the Protrepticus) that exhorted the youth to do philosophy. Although the popular work has been lost, efforts to reconstruct it have met with some success, and it is possible to detect its influence on various works in the Aristotle Corpus that have survived. The 13 original essays in this volume examine protreptic aspects of Aristotle’s works, including the a…Read more

    In the first part of _De Partibus Animalium_ I.5, Aristotle encourages his audience to engage in a novel kind of philosophy: the scientific inquiry into animals and plants (hereafter: biology): “Since we have completed stating the way things appear to us about divine things, it remains to speak about animal nature, omitting nothing in our power”; “one should approach research about each of the animals without disgust, since in every one there is something natural and beautiful”. The kind of disc…Read more

    This is the 2017 draft of our translation of our reconstruction of Aristotle's lost work, the Protrepticus (Exhortation to Philosophy). The front matter indicates how to cite the work and the translation. We are currently in the process of preparing a critical Greek edition and commentary. In the meantime, this version has been cited in several publications.

    Biology and theology are interdependent theoretical sciences for Aristotle. In prominent discussions of the divine things (the stars and their unmoved movers) Aristotle appeals to the science of living things, and in prominent discussions of the nature of plants and animals Aristotle appeals to the nature of the divine. There is in fact a single continuous series of living things that includes gods, humans, animals, and plants, all of them in a way divine. Aristotle has this continuum of divine …Read more

    Aristotle’s interpretation of Democritus’ concept of the void as a kind of "place" has been called into question by modern historians of philosophy. The modest aim of the present essay is to argue that Aristotle’s description is reasonably charitable and accurate and affords the basis—the only possible basis—for a coherent reconstruction Democritus’ theory.

    Aristotle’s dialogue Protrepticus is not only his earliest work of ethics but also the root of all his subsequent investigations into ethics. Here we explore the various ways Aristotle retained in memory the contents of the Protrepticus and redeployed them in the Eudemian Ethics, including the common books. Since Aristotle himself does not explicitly acknowledge the foundational significance of the Protrepticus to his later works, our exploration must proceed on the basis of our knowledge of the…Read more

    The Medical Background and Inductive Basis of Aristotle’s Doctrine of the Mean
    In Hynek Bartoš & Vojtěch Linka (eds.), Aristotle reads Hippocrates, Brill. pp. 351-374. 2024.
    Two arguments in Eudemian Ethics 2 that are crucial to Aristotle’s definition of moral virtue as a mean state contain claims that Aristotle says are clear by induction. In these contexts, he explicitly appeals to examples coming from arts and sciences like gymnastic training and medicine for evidence. But Aristotle does not here, or elsewhere (at least in any extant work), including the parallel arguments in the Nicomachean Ethics, actually supply or discuss the evidence that makes these inducti…Read more

    Democritus, The Laughing Philosopher
    The Philosophy of Humor Yearbook 5 (1): 1-28. 2024.
    I argue that a circa first century B.C./A.D. anonymous epistolary comic novel depicting a fictional interaction between Hippocrates of Cos and Democritus of Abdera contains an insightful imitation of Democritus that can cast light on the historical Democritus’s thought, including his thought on the touchy subject of appropriate and inappropriate laughter. The only thing certain about Democritus’s view of laughter is that he denounced laughter at human misfortune as inappropriate. The later legen…Read more

    In his adventurous monograph in comparative philosophy, The Origins of Philosophy in Ancient Greece and Ancient India, Richard Seaford offers to explain why philosophy, which on his account originated in the sixth century BCE separately in both Greece and India, took such a similar form in both cultures.

    Why did Aristotle invent the material cause ? The early development of the concept of hê hylê
    In Pierre Pellegrin & Françoise Graziani (eds.), L'HÉRITAGE D'ARISTOTE AUJOURD'HUI : NATURE ET SOCIÉTÉ, Alessandria: Editzioni Dell'orso. pp. 59-86. 2020.
    I present a developmental account of Aristotle’s concept of hê hylê (usually translated “the matter”), focused the earliest developments. I begin by analyzing fragments of some lost early works and a chapter of the Organon, texts which indicate that early in his career Aristotle had not yet begun to use he hylê in a technical sense. Next, I examine Physics II 3, a chapter in which Aristotle conceives of he hylê not as a kind of cause in its own right, but merely as an example of the so-called “o…Read more

    On Law and Justice Attributed to Archytas of Tarentum
    In David Conan Wolfsdorf (ed.), Early Greek Ethics, Oxford University Press. pp. 455-490. 2020.
    Archytas of Tarentum, a contemporary and associate of Plato, was a famous Pythagorean, mathematician, and statesman of Tarentum. Although his works are lost and most of the fragments attributed to him were composed in later eras, they nevertheless contain valuable information about his thought. In particular, the fragments of On Law and Justice are likely based on a work by the early Peripatetic biographer Aristoxenus of Tarentum. The fragments touch on key themes of early Greek ethics, includi…Read more

    The Ethical Maxims of Democritus of Abdera
    In David Conan Wolfsdorf (ed.), Early Greek Ethics, Oxford University Press. pp. 211-242. 2020.
    Democritus of Abdera, best known as a cosmologist and the founder of atomism, wrote more on ethics than anyone before Plato. His work Peri euthumiês (On Contentment) was extremely influential on the later development of teleological and intellectualist ethics, eudaimonism, hedonism, therapeutic ethics, and positive psychology. The loss of his works, however, and the transmission of his fragments in collections of maxims (gnomai), has obscured the extent his contribution to the history of systema…Read more

    Meteorology
    In Liba Taub (ed.), The Cambridge Companion to Ancient Greek and Roman Science, Cambridge University Press. pp. 160-184. 2020.
    Greco-Roman meteorology will be described in four overlapping developments. In the archaic period, astro-meteorological calendars were written down, and one appears in Hesiod’s Works and Days; such calendars or almanacs originated thousands of years earlier in Mesopotamia. In the second development, also in the archaic period, the pioneers of prose writing began writing speculative naturalistic explanations of meteorological phenomena: Anaximander, followed by Heraclitus, Anaxagoras, and others.…Read more

    The Medical Background of Aristotle's Theory of Nature and Spontaneity
    Proceedings of the Boston Area Colloquium of Ancient Philosophy 27 105-152. 2012.
    An appreciation of the "more philosophical" aspects of ancient medical writings casts considerable light on Aristotle's concept of nature, and how he understands nature to differ from art, on the one hand, and spontaneity or luck, on the other. The account of nature, and its comparison with art and spontaneity in Physics II is developed with continual reference to the medical art. The notion of spontaneous remission of disease (without the aid of the medical art) was a controversial subject in t…Read more

    Hynek Bartos does the field of ancient philosophy a great service by detailing the influence of early Greek thinkers (such as Heraclitus, Empedocles, Anaxagoras, Democritus, and Diogenes of Apollonia) on the Hippocratic work On Regimen, and by demonstrating that work’s innovative engagement with contemporary scientific and philosophical concepts as well as its direct influence on Plato and Aristotle. His study usefully counteracts the lamentable tendency among ancient philosophers to ignore or d…Read more

    Aristotle on Kosmos and Kosmoi
    In Phillip Sidney Horky (ed.), Cosmos in the Ancient World, Cambridge University Press. pp. 74-107. 2019.
    The concept of kosmos did not play the leading role in Aristotle’s physics that it did in Pythagorean, Atomistic, Platonic, or Stoic physics. Although Aristotle greatly influenced the history of cosmology, he does not himself recognize a science of cosmology, a science taking the kosmos itself as the object of study with its own phenomena to be explained and its own principles that explain them. The term kosmos played an important role in two aspects of his predecessor’s accounts that Aristotle …Read more

    Protreptic and Apotreptic: Aristotle's dialogue Protrepticus
    In Olʹga Alieva, Annemaré Kotzé & Sophie van der Meeren (eds.), When Wisdom Calls: Philosophical Protreptic in Antiquity, Brepols Publishers. pp. 111-154. 2018.
    This paper has three major aims. The first is to defend the hypothesis that Aristotle’s lost work Protrepticus was a dialogue. The second is to explore the genres of ancient apotreptics, speeches that argue against doing philosophy and show the need for protreptic responses; our exploration is guided by Aristotle’s own analysis of apotreptics as well as protreptics in his Rhetorica. The third aim is to restore to the evidence base of Aristotle’s Protrepticus an apotreptic speech that argues agai…Read more

    Early Pyrrhonism as a Sect of Buddhism? A Case Study in the Methodology of Comparative Philosophy
    with Brett Shults
    Comparative Philosophy 9 (2): 1-40. 2018.
    We offer a sceptical examination of a thesis recently advanced in a monograph published by Princeton University Press, entitled Greek Buddha: Pyrrho’s Encounter with Early Buddhism in Central Asia. In this dense and probing work, Christopher I. Beckwith, a professor of Central Eurasian studies at Indiana University, Bloomington, argues that Pyrrho of Elis adopted a form of early Buddhism during his years in Bactria and Gandhāra, and that early Pyrrhonism must be understood as a sect of early Bud…Read more
