The author argues that ancient Skepticism may be most suited to deal with two crises in the Age of COVID-19: both the physical or epidemiological aspects of the pandemic, and the epistemological and ethical crisis of increasing disbelief in the sciences. Following Michel Bitbol, I suggest one way to mitigate this crisis of faith may be for science to become more epistemically modest, renouncing some of its claims to describe reality as it objectively is, and adopting an “intransitive” rather than (...) a “transitive” approach to Nature. This was the attitude adopted by the Greco-Roman medical school of the Empirics, which may also be of assistance in combatting the urgent problem of Fake News. The epistemology of Skepticism and the scientific methodology of the closely related Medical Empiricism shows that an epistemically modest, non-interventionist approach to science is quite compatible with a robust and sophisticated proto-experimental scientific methodology.

Preview: 2020, the year the coronavirus pandemic spread globally, marked the twenty-fifth year since the publication of Pierre Hadot’s work Philosophy as a Way of Life. In that time, what began as the research specialization of just a few scholars has become a growing area of philosophical and metaphilosophical inquiry, bringing together researchers from around the globe. Hadot’s key ideas of spiritual exercises, and the very idea of PWL, have been applied to a host of individual thinkers from across the (...) history of philosophy: from the Hellenistic and Roman-era philosophers of direct concern to Hadot, through renaissance thinkers like Petrarch, Lipsius, Montaigne, Descartes, or Bacon, into nineteenth-century thinkers led by Schopenhauer, Kierkegaard, and Nietzsche.In more recent years, more global reflections on the “very idea” of PWL have begun to emerge, as well as dedicated journal editions. In these more recent PWL studies, some of the manifold research questions have begun to be explored, which were opened up by the studies of Pierre and Ilsetraut Hadot, as well as its reception in Michel Foucault’s later work. What implications, after all, does understanding the history of PWL, and the predominance of this metaphilosophical conception in the history of Western thought, have for how we understand the practice of philosophy today? Does recovering the alternative understandings of philosophy as a practice in history necessarily lead to a criticism of contemporary, solely academic or theoretical modes of philosophizing, or is the idea of PWL one which has only historiographical force?

ABSTRACT: With a view to suggesting the possible relevance of Aristotelian thought to current notions of complexity and self-organization, studies Aristotlenard cells, and the theories of Schneider, Kay, and D. Sagan.

This article seeks to show that the views on time and eternity of Plotinus and Boethius are analogous to those implied by the block-time perspective in contemporary philosophy of time, as implied by the mathematical physics of Einstein and Minkowski. Both Einstein and Boethius utilized their theories of time and eternity with the practical goal of providing consolation to persons in distress; this practice of consolatio is compared to Pierre Hadot’s studies of the “Look from Above”, of the importance of (...) concentrating on the present moment, and his emphasis on ancient philosophy as providing therapy for the soul, instead of mere abstract speculation for its own sake. In the first part of the article, Einstein’s views are compared with those of Plotinus, and with the elucidation of Plotinus’ views provided in the Arabic Theology of Aristotle. The second part of the article studies Boethius’ Consolation of Philosophy, which, contrary to recent interpretations, is indeed a genuine consolation rather than a parody thereof. The Consolation shows how the study of the Neoplatonic philosophical curriculum can lead the student along the path to salvation, by awakening and elaborating his innate ideas. To illustrate this doctrine, a passage from the little-known PseudoBoethian treatise De diis et praesensionibus is studied. Finally, after a survey of Boethius’ view on fate and providence, and Aristotle’s theory of future contingents, I study Boethius’ three main arguments in favor of the reconcilability of divine omniscience and human free will: the distinction between absolute and conditional necessity, the principle that the nature of knowledge is determined by the knower, and finally the doctrine that God lives in an eternal present, seeing past, present, and future simultaneously. This last view, developed primarily from Plotinus, is once again argued to be analogous to that advocated by contemporary block-time theorists on the basis of Eisteinian relativity. God’s supratemporal vision introduces no necessity into contingent events. Ultimate, objective reality, for Boethius as for Plotinus and Einstein, is atemporal, and our idea that there is a conflict between human free will and divine omniscience derives from a kind of optical illusion, caused by the fact that we cannot help but think in terms of temporality.

The chapter presents a brief case study, in which we can observe the impact of Pierre Hadot's ideas on Martin O’Hagan, a person not far removed from us in terms of space, time, and aspirations. Hadot's concept of “Philosophy as a Way of Life (PWL)” could provide an option for a person who, excluded from and/or disillusioned by Academic philosophy, still felt the need to search for answers to a few centrally important questions that had direct impact on his life. (...) Even the characteristic that has returned like a Leitmotif throughout this chapter — analytic philosophy's tendency to ignore the so‐called Big Questions, such as that of the meaning of life — can be illuminated by means of Kuhn's theories. The author hopes that the interest in Hadot's concept of PWL will contribute to the rehabilitation of philosophy as it was before its takeover by Academic philosophy. (shrink)

An investigation of the views on space and time of the Russian polymath Pavel Florensky. After a brief account of his life, I study Florensky’s conception of time in The Meaning of Idealism, where he first confronts Einstein’s theory of special relativity, comparing it to Plato’s metaphor of the Cave and Goethe’s myth of the Mothers. Later, in his Analysis of spatiality and time, Florensky speaks of a person’s biography as a four-dimensional unity, in which the temporal coordinate is examined (...) in sections. In On the Imaginaries in Geometry, Florensky argues that the speed of light is not, as in Relativity, an absolute speed limit in the universe. When bodies approach and then surpass the speed of light, they are transformed into unextended, eternal Platonic forms. Beyond this point, time runs in reverse, effects precede their causes, and efficient causality is transformed into final or teleological causality, a concept on which Florensky elaborates in his Iconostasis. Florensky thus transformed the findings of Einsteinian relativity in order to make room for Plato’s intelligible Ideas, the Aristotelian distinction between a changing realm of earth and the immutable realm of the heavens, and the notion of teleology or final causation. His notion that man can approximate God’s vision of past, present and future all at once, as if from above, is reminiscent of Boethius’ ideas. (shrink)

En este artículo se investigan los orígenes griegos y latinos de la máxima escolástica que dicta que lo primero en la composición es lo último en la resolución. Estudio a la tradición que sostuvo que la síntesis procede de lo anterior a lo posterior, mientras que el análisis procede de lo posterior a lo anterior. En primer lugar, busco los orígenes de estas nociones en las matemáticas griegas. Posteriormente me ocupo de autores del platonismo medio, quienes identificaron el análisis con (...) la diairesis platónica. Paso después a un breve estudio de las nociones de análisis y síntesis en algunos neoplatónicos. Muestro que tanto la versión matemática como la filosófica del método analítico/sintético se asoció con varios contextos nuevos. (shrink)

"Simplicius starts with a survey of previous commentators and an introductory set of questions about Aristotle's philosophy and about the Categories in particular. The commentator, he says, needs to present Plato and Aristotle as in harmony in most things."-- Publisher description.

One of his six introductions to philosophy, widely used by students in Alexandria, Ammonius' lecture on Porphyry was recorded in writing by his students in the commentary translated here. Along with five other types of introductions (three of which are translated in the Ancient Commentators on Aristotle volume Elias and David: Introductions to Philosophy with Olympiodorus: Introduction to Logic) it made Greek philosophy more accessible to other cultures. These introductions became standard in Ammonius' school and included a popular set of (...) five or more definitions of philosophy, some of them drawn from commentaries on quite different works. Ammonius' lecture expounded the most celebrated and discussed previous introduction written by Porphyry 200 years earlier, which was devoted to five main technical terms of Aristotle's logic. Ammonius was sympathetic to Porphyry because they both sought to harmonise the views of Plato and Aristotle with each other, arguing in different ways that the two philosophers did not disagree about the nature of universals. Porphyry's introduction was a hugely influential work for centuries after its composition, and this commentary by Ammonius served to maintain its position at the centre of later schools of philosophy. This English translation of Ammonius' work is the latest volume in the Ancient Commentators on Aristotle series and makes this philosophical work accessible to a modern readership. The translation is accompanied by an introduction, comprehensive commentary notes, bibliography, glossary of translated terms and a subject index. (shrink)

This memorial essay on the French historian of philosophy Pierre Hadot (1922–2010) explores his life and work. Starting out from an ecclesiastical background and education, Hadot's interest in mysticism led him to study the late Greek Neoplatonists Plotinus and Porphyry, as well as the Latin Church Fathers. Elected first to the École pratique des hautes études and then to the Collège de France, Hadot developed his most influential idea, that ancient philosophy was not the construction of an abstract system of (...) ideas, but a concrete, lived practice intended to transform the perception and being of the practitioner, and thereby to ensure his or her happiness. Later in his career, Hadot, influenced by German Romanticism and above all by Goethe, turned to study the history of the concept of nature from classical to modern times. The breadth of his interests and the novelty of his approach account for the wide interest in his works, extending to circles that extend far beyond the disciplines of classical studies and the history of philosophy.

This article studies the debate between the Neoplatonist philosophers Simplicius and John Philoponus on the question of the eternity of the world. The first part consists in a historical introduction situating their debate within the context of the conflict between Christians and Pagan in the Byzantine Empire of the first half of the sixth century. Particular attention is paid to the attitudes of these two thinkers to Aristotle's attempted proofs of the eternity of motion and time in Physics 8.1. The (...) second part traces the origins, structure and function of a particular argument used by Philoponus to argue for the world's creation within time. Philoponus takes advantage of a tension inherent in Aristotle's theory of motion, between his standard view that all motion and change is continuous and takes place in time, and his occasional admission that at least some kinds of motion and change are instantaneous. For Philoponus, God's creation of the world is precisely such an instantaneous change: it is not a motion on the part of the Creator, but is analogous to the activation of a state, which is timeless and implies no change on the part of the agent. The various transformations of this doctrine at the hands of Peripatetic, Neoplatonic, and Islamic commentators are studied, as is Philoponus' use of it in his debate against Proclus. (shrink)

This contribution continues the comparison between ancient and modern beliefs on scientific cosmology which began in a previous article in this Journal. I begin with a brief survey of contemporary theories on Big Bang cosmology, followed by a study of the cosmological theories of the Presocratic thinker Pherecydes of Syros. The second part of my paper studies the ramifications of the basic Platonic principle that bonum est diffusivum sui. I begin by studying the vicissitudes of this theory in the Patristic (...) thought of Origen, the Arians, and Athanasius. Following Willy Theiler, I suggest that similarities between the views of Origen and the Neoplatonist philosopher Porphyry of Tyre may be traceable to Plotinus' teacher Ammonius Saccas. Finally, following Endress, I study the way the Arabic translation of some propositions from Proclus' Elements of Theology were accompanied by interpolated glosses derived from the Christian Neoplatonist John Philoponus, which were designed to make Proclus' thought more acceptable to a creationist, Monotheistic belief system such as Islam. Philoponus' theories of instantaneous creation were taken up, thanks to al-Kindi, by the Neoplatonica Arabica, whence they exerted an important influence on the development of Islamic thought. An Appendix of texts with translation and bibliography completes the article. (shrink)

This introductory chapter of Philosophy as a Way of Life: Ancients and Moderns — Essays in Honor of Pierre Hadot talks about the life of Pierre Hadot. The author's memories of his close friendship with Pierre Hadot are presented. In the 1970s, Hadot began to accord more and more importance to the idea of spiritual exercises, that is, philosophical practices intended to transform the practitioner's way of looking at the world and consequently his or her way of being. These exercises, (...) involving not just the intellect or reason, but all of a human being's faculties, including emotion and imagination, had the same goal as all ancient philosophy: reducing human suffering and increasing happiness, by teaching people to detach themselves from their particular, egocentric, individualistic viewpoints and become aware of their belonging, as integral component parts, to the Whole constituted by the entire cosmos.

Studies the threefold hierarchy of certainty, from its origins in Mahāyāna Buddhism, through Islam, to 17th century China. This tripartite scheme may be traced back to the ancient Buddhist scheme of the threefold wisdom as systematized by Vasubandhu of Gandhāra in the 4th-5th centuries CE. Following the advent of Islam in the 8th century, it was combined with Qur'anic notions of certainty. Initially taken up by early Islamic mystics such as Sahl al-Tustarī and al-Ḥākim al-Tirmiḏī, the notion of yaqīn was (...) gradually systematized into the three-level hierarchy of “knowledge or science of certainly”, “essence” of certainty, and “truth or reality of certainty”, a hierarchy that bears a distinct resemblance to the Buddhist threefold path of wisdom as discussed by Marc-Henri Deroche. Half a millennium later, this threefold hierarchy of levels of certainty, remotely inspired by Buddhism and integrated into the philosophical Sufism of Ibn ʿArabī and his Persian disciple Jāmī, this complex of ideas may have resurfaced in 17th century China.

Since its original publication in France in 1963, Pierre Hadot's lively philosophical portrait of Plotinus remains the preeminent introduction to the man and his thought. Michael Chase's lucid translation—complete with a useful chronology and analytical bibliography—at last makes this book available to the English-speaking world. Hadot carefully examines Plotinus's views on the self, existence, love, virtue, gentleness, and solitude. He shows that Plotinus, like other philosophers of his day, believed that Plato and Aristotle had already articulated the essential truths; for (...) him, the purpose of practicing philosophy was not to profess new truths but to engage in spiritual exercises so as to live philosophically. Seen in this light, Plotinus's counsel against fixation on the body and all earthly matters stemmed not from disgust or fear, but rather from his awareness of the negative effect that bodily preoccupation and material concern could have on spiritual exercises.

Studies the doctrine of providence of the Neoplatonic philosopher Porphyry of Tyre. Following a survey of Hellenistic theories of fate and providence, the doctrine of destiny ex hupotheseos, developed on the basis of Plato’s dialogues, is examined : according to it, our acts are free, but their consequences are necessary. As an integral part of Middle Platonic philosophy, this theory was probably transmitted to Late Antiquity by Porphyry. We then move on to examine Porphyry’s treatise On what depends on us, (...) which contains an interpretation of Plato’s Myth of Er, and develops the doctrine of the twofold choice of lives. Nemesius and Proclus react, each in his own way, against the individualism of Porphyry’s approach. In conclusion, the theory of fate and providence in Boethius’ Consolation of Philosophy is briefly examined. (shrink)

One of the most influential historians of ancient philosophy of the past half-century, Pierre Hadot was adept at using ancient philosophers to illuminate the relevance of their ideas to contemporary life. This new edition of _The Present Alone is Our Happiness_, which has been significantly revised and expanded to include two previously untranslated essays, is an ideal introduction to some of Hadot's more scholarly work. In it, we discover that to be an Epicurean is not merely to think like one; (...) it is to adopt a way of living where limiting desires is the condition for happiness. Being an Aristotelian, similarly, is to choose a life that involves contemplation, and being a Cynic is to follow Diogenes in his refusal of quotidian convention and the mentality of ordinary people. If so many ancient philosophers founded schools, Hadot explains, it was precisely because they were proposing how to live life on a daily basis. We learn here that the history of philosophy has been something more than just that of a discourse. The founding texts of Greek philosophy, after all, were notes taken from oral exercises undertaken in concrete circumstances and contexts, most often a dialogue between students and specific interlocutors who meant to shed light on their students' real existence. The immense contribution of this book, which also traces Hadot's own personal itinerary in a touching manner, is to remind us, through direct language and numerous examples, what the theoretical aspect of philosophy often masks: its vital and existential dimensions.
