Empedocles’ B100 contains an analogy between a girl handling a clepsydra and respiration. This article argues that proposals to establish Love or Persephone as the girl’s respiratory equivalent are rendered unlikely by differences between their respective causal roles. Rather than her gender, this article emphasises the importance of the girl’s age: Empedocles required a playful child to handle the clepsydra. This child’s play results in the extra phase of submerging the clepsydra while the upper vent is open, which Empedocles needed (...) to form a parallel for the first static phase of respiration.

The recognition of striking regularities in the physical world plays a major role in the justification of hypotheses and the development of new theories both in the natural sciences and in philosophy. However, while scientists consider only strictly natural hypotheses as explanations for such regularities, philosophers also explore meta-natural hypotheses. One example is mathematical realism, which proposes the existence of abstract mathematical entities as an explanation for the applicability of mathematics in the sciences. Another example is theism, which offers the (...) existence of a supernatural being as an explanation for the design-like appearance of the physical cosmos. Although all meta-natural hypotheses defy empirical testing, there is a strong intuition that some of them are more warranted than others. The goal of this paper is to sharpen this intuition into a clear criterion for the admissibility of meta-natural explanations for empirical facts. Drawing on recent debates about the indispensability of mathematics and teleological arguments for the existence of God, I argue that a meta-natural explanation is admissible just in case the explanation refers to an entity that, though not itself causally efficacious, guarantees the instantiation of a causally efficacious entity that is an actual cause of the regularity.

Despite the fact that the theory of Forms is regarded as the hallmark of Plato’s philosophy, it has remained remarkably elusive, because it is more hinted at than explained in his dialogues. Given the uncertainty concerning the nature and extension of the Forms, this article makes no pretense to coming up with solutions to all problems that have occupied scholars since antiquity. It aims to elucidate only two aspects of that theory: the indication in certain dialogues that the Forms are (...) what in modern parlance are called functions or purposes, and the indication in other dialogues that such functions rely on harmonious structures.

Readers of Plato since antiquity have generally taken Socrates’ intellectual autobiography in the Phaedo as a signal of his turn away from the study of natural philosophy. They have turned instead to characters such as Timaeus for evidence of Plato’s pursuit of physics. This article argues that Plato’s Socrates himself developed a philosophy of nature in his criticism of Anaxagoras and his subsequent philosophic pursuits. Socrates’ autobiography places the study of nature in a foundational position within the development of his (...) philosophic method. In the Apology, Socrates further elaborated his investigation into nature through his understanding of theology. Finally, in the Phaedrus, Socrates connects the study of nature with the study of rhetoric as tools for virtue. Therefore, Plato’s Socrates does not reject or abandon physics, as has often been suggested, but rather, he incorporates it into his own philosophic project and challenges its practitioners to connect their own inquiries with human affairs.

وجه الوهی فلسفه ارسطو، و به طور خاص وجه الوهی غایت‌شناسی او، مسئله‌ای مناقشه‌برانگیز و حتی شدیداً مورد انکار است؛ چرا که تفسیرهای معاصر غایت‌شناسی، از یک سو غایت‌شناسی الهیاتی را تبیین جهان به عنوان فعل قصدمندانه خالقی حکیم تلقی کرده، و از سوی دیگر غایت‌شناسی ارسطو را صرفاً روشی برای تبیین کارکردهای جواهر طبیعی و افعال انسانی می‌دانند. در نتیجه غایت‌شناسی ارسطو فاقد هر گونه دلالت الهیاتی تلقی می‌شود. این نوشتار با نظر به اوصاف امر الهی در اندیشه ارسطو (...) نشان می‌دهد که او در حوزه زیست‌شناسی و اخلاق، گرچه پای تبیین‌های غایت‌شناختی به معنای طراحی هوشمند را به میان نمی‌کشد، در عین حال، کارکرد نهایی انواع طبیعی زنده و نوع انسان را با ارجاع به عنصری الهی در آنها تبیین می‌کند. به بیان مشخص‌تر، در انواع طبیعی زنده فقط نوع است که از جهت سرمدیت‌اش در جایگاه غایت به معنای حقیقی قرار می‌گیرد، حال آن که در انسان، غایت نهایی با ارجاع به عنصر الوهی محقق در هر فرد یعنی عقل احراز می‌شود. پس خدا به عنوان نمونۀ ایدئال تحققِ حیاتِ سرمدیِ معقول لحاظ می‌شود و غایتمندی جهان طبیعی زنده و جهان انسانی چیزی نیست مگر تشبه به این حیات سرمدی. بنابراین غایت‌شناسی ارسطو واجد استلزامات صریح الهیاتی است و چهارچوبی هستی‌شناختی را برای تفسیر عقلانی مفهوم سعادت در فلسفه‌های دینی فراهم می‌سازد.

The paper provides an innovative interpretation of the treatise De Victu, showing that, though Heraclitean, Anaxagorean and Empedoclean borrowings in the work are certainly pervasive, the author also develops a sophisticated and multi-purpose explanatory framework, which, being based on an original conception of the nature of man, the cosmos and the relationship between the two, provides an effective foundation for the medical enterprise, allowing him to propose his dietetics as a ‘way of life’. At the core of this enterprise is (...) the relationship between microcosm and macrocosm: in virtue of this relationship, I submit, the cosmos becomes both an active factor to be taken into account for the maintenance of individual physical well-being and the normative standard to which a dietician and whoever cares about health must refer in order to live the healthiest possible life.

Aristotle’s soul is a first principle (an ‘efficient cause’) of every vital change in an animal, in the way that a craft is a cause of its product’s coming-to-be. We argue that the soul’s causal efficacy cannot therefore be reduced to the formal constitution of vital phenomena, or to discrete interventions into independently constituted processes, but involves the exercise of vital powers. This reading does better justice to Aristotle’s conception of craft as a rational productive disposition; and it captures the (...) soul’s continuous causal role as that which brings about all forms of vital change and underwrites their unity.

> καὶ πῶς τις ἀνάξει αὐτοὺς εἰς φῶς, ὥσπερ > > ἐξ Ἅιδου λέγονται δή τινες εἰς θεοὺς ἀνελθεῖν; > > Plato Republic 521c This study reconstructs Empedocles’ eschatology and cosmology, arguing that they presuppose one another. Part one surveys body and soul in Empedocles and argues that the transmigrating daimon is a long-lived compound made of the elements air and fire. Part two shows that Empedocles situates our current life in Hades, then considers the testimonies concerning different cosmic levels (...) in Empedocles and compares them with the afterlife schemes in Pindar’s Second Olympian Ode and Plato’s Phaedo myth. Part three offers a new edition of section d lines 5–10 of the Strasbourg papyrus of Empedocles that reinforces the connection between transmigration and different cosmic locations for souls. Part four reconstructs Empedocles’ cosmology, identifies three different levels or habitats of soul, and, more tentatively, suggests that Empedoclean “long-lived gods” are best understood as stars.

Scholars looking back to the earliest stirrings of the philosophical tradition in ancient Greece have often seen a rational approach to nature cleaving itself off from an older approach, that of the mythographer. If this account were right, we would have here a major (and perhaps the ?rst major) drawing of an epistemic boundary. There are, however, mounting reasons to question this narrative that have been accumulating across several modern disciplines. This paper explores the most important challenges to the myth-to-science (...) narrative and suggests that the different ways of framing the ancient debates have much to do with the boundaries between modern disciplines and/or academic cultures.

In this article, it is argued that, although there is significant debate over the nature of Anaxagoras' response to Parmenides, it is likely that Anaxagoras advances his physical theory in opposition to Parmenides' Numerical Monism. It is unlikely that Anaxagoras aims to develop a theory that harmonizes with the Predicational Monism that is sometimes ascribed to Parmenides. In addition, it is argued that, although some modern scholars suggest that Anaxagoras posits nous as a planning cause, no compelling argument has yet (...) been advanced against Plato's interpretation, according to which Anaxagoras is not a proponent of teleological explanation.

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.

How is moral thinking, ethics, related to evolutionary theorizing? There are two approaches, epitomized by Charles Darwin who works under the metaphor of the world as a machine, and by Herbert Spencer who works under the metaphor of the world as an organism. Although the author prefers the first approach, the aim of this paper is to give a disinterested account of both approaches.

Burnet's text at Pl. Ti. 55c7–d6 is at least questionable, and opting for a different reading at 55d5 would shed light on an intriguing argumentative aspect of Plato's cosmological account: God confirms the metaphysical reasons why there is just one perfect world.

This paper argues that a debate between Toland and Clarke is the intellectual context to help understand the motive behind the critic and the significance of Berkeley's response to the critic in PHK 60-66. These, in turn, are responding to Boyle's adaptation of a neglected design argument by Cicero. The paper shows that there is an intimate connection between these claims of natural science and a once famous design argument. In particular, that in the early modern period the connection between (...) the scientific revolution and a certain commitment to final causes, and god's design, is more than merely contingent. The details of PHK 60-66 support the idea that the critic is responding to concerns that by echoing features of Toland's argument Berkeley undermines the Newtonian edifice Clarke has constructed.

The reconstruction of ensemble d–f of the Akhmîm Papyrus, better known as the Strasbourg Papyrus, which attests approximately eighteen of the over seventy new lines of Empedocles’ physical poem, has drawn the attention of scholars over recent years. Thanks to the good condition of the papyrus and the coincidence with two Empedoclean lines, already known from the indirect tradition, ensemble d–f 1–10a presents a well-restored text and an intelligible sense. In contrast, because of the damaged state of the papyrus, the (...) restoration of d–f 10b–18 is more complicated. These lines seem to describe a life-generative process, but what process was Empedocles talking about? Some resemblances between these papyrus lines and the lines of another Empedoclean fragment, DK 31 B 62, have suggested to scholars, notably to A. Martin and O. Primavesi in 1999 and M. Rashed in 2011, that the lines of the papyrus depict, just like DK 31 B 62, the generation of whole-natured beings. Other scholars, however, such as R. Janko in 2004 and A. Laks and G.W. Most in 2016, show more caution and leave the possibility open that Empedocles is here talking about the generation of something else. (shrink)

Arguments are advanced that ethics provide the building blocks for the cultural evolution of those forms of behaviour that distinguish different human moral communities. To perform this function ethical variants need to be maintained within communities over many generations and this is achieved by religious prescription enshrining the ethical variants. This gives religions their essential function. It also follows that ethics themselves must evolve and be subject to natural selection. Some ethical variants and their possible survival value are discussed. This (...) survival value is clearly distinct from the reasons that the variants were introduced. Finally, the consequences for ethical evolution arising from the change of humans from an endangered to an endangering species are considered. (shrink)

زبان دین خواهان کشف و تببین ماهیت زبانی است که در الفاظ و گزاره‌های دینی به کار رفته است. این کشف به ما کمک می‌کند تا مراد اصلی یا فحوای حقیقی مضامین دینی را که در قالب زبان بشری بیان شده است دریابیم. غزالی، متأثر از نگرش‌های کلامی و یافته‌های عرفانی خود و با لحاظ مراتب مختلف ادراک مردمان، دیدگاه‌های متفاوتی را در این موضوع ابراز داشته است. از این رو، گاه اجتناب از تأویل را لازم می‌داند، گاه ضرورت عدول (...) از معنای ظاهر را خاطرنشان می‌سازد و گاه با بحث از «روح معنا» که خود طراح آن است، بدون آن که معنای ظاهر انکار شود، گوهر حقیقی معنا را فارغ از ویژگی‌های مصادیق آن منظور می‌نماید. در عین حال، جریان اندیشۀ او در این باب به منزل اشتراک لفظی نیز ورود می‌کند و پایان سیر آن در معناشناسی اوصاف‌ الهی چنین است که حقیقتش نصیب فهم هیچ کس نخواهد شد و معانی آن در صید هیچ ادراکی درنخواهد آمد.

El presente artículo aborda las connotaciones y los fundamentos de la paráfrasis cum canere vellem en Serv. Ecl. 6. 3. El análisis del sentido del verbo volo en este contexto y la confrontación del pasaje con Serv. Ecl. 6. 5 revelan que Servio interpreta la frase cum canerem reges et proelia como referencia a un temprano empeño de Virgilio en componer poesía épica, del que pronto desistió. Esta interpretación está condicionada por la idea de que la secuencia cronológica Églogas - (...) Geórgicas - Eneida tiene un correlato jerárquico, idea que se funda en noticias biográficas y en la teoría de la tripertita varietas. This paper focuses on the connotations and grounds of the paraphrase cum canere vellem in Serv. Ecl. 6. 3. The analysis of the sense of verb volo within this context, as well as the confrontation between that passage and Serv. Ecl. 6. 5, show that Servius interprets the clause cum canerem reges et proelia as a reference to Virgil's early endeavor to compose an epic poem, from which he shortly desisted. This interpretation is conditioned by the idea that the chronological sequence Eclogues - Georgics - Aeneid has a hierarchical correlate, an idea which is founded on biographical information and the theory of tripertita varietas.

The Greek and Roman atomistic tradition (whose most famous representatives are Democritus, Epicurus and Lucretius), defends radical and immanentist ideas about the discovery of technologies in human societies. The appearance of new technologies, insofar as it is due to the satisfaction of human needs and derives from natural necessity, reveals that human work is in some way a natural process. Consequently, human beings do not need any kind of Promethean intervention, which would provide them with new skills and technologies. However, (...) the Epicurean tradition, as evidenced by several texts (especially in Lucretius), echoes the mythological figure of Prometheus, in showing that human beings, through their discoveries, are independent from the gods. Epicurus himself, in Lucretius’ De rerum natura, embodies, like Prometheus, the ideal of human emancipation from superstitious representations of the gods. It does not mean, however, that work and technical discoveries are the best means of emancipation: for Epicurus and his followers, philosophy itself remains the safest way to tranquillity and freedom.
