Aristotle: Natural Science

At least since Foster (2002), scholars interested in Aristotle’s views about environmental ethics have focused primarily upon his teleological account of non-human animals as the basis for an Aristotelian environmental virtue ethics. But although Aristotle’s scientific account of non-human animals can serve as the basis for a form of environmental ethics akin to “nature preservation,” one finds in his account of “household management” (or oikonomikē) a very different sort of environmental ethic, one that looks much more like a form of (...) “nature conservation.” My paper argues that for Aristotle, oikonomikē is indeed both “environmental” and an “ethic.” The first part of my chapter shows that oikonomikē is fundamentally environmental insofar as it concerns what Aristotle in Politics 1.8 calls “property acquisition in accord with nature” or “true wealth” (Pol. 1.8.1256b26–27, 30–31), namely the prudential use of natural resources in a way that recognizes the dependence of ways of life upon different habitats or environments. The second part of my chapter shows that oikonomikē is also an “ethic” insofar as it embeds three different kinds of limit on the use of animate and inanimate natural resources, namely that natural resource use is subordinate to expertise about the happiness of the political community (or what Aristotle calls “politics” [πολιτική]); that natural resource use, as an instrumental good, is limited and governed by the craft or expertise of oikonomikē; and that notions of unlimited commercial “wealth acquisition” (χρηματιστική) are based on ethically problematic ways of life. After showing that Aristotle’s account of oikonomikē is indeed an environmental ethic, the third part of my chapter considers the objection that oikonomikē is a weak environmental ethic insofar as it is exploitatively or axiological anthropocentric. I respond that Aristotle’s account of non-human animal domestication provides conceptual resources for thinking about non-human animals as subordinate members in one’s ecological-political community, especially with respect to his invocation of the craft analogy (in the example of shepherds) and inter-species utility friendships. Although Aristotle has multiple sources relevant for understanding environmental ethics, his account of oikonomikē is both a neglected source and a potentially fruitful one. (shrink)

Aristotle offers apparently inconsistent explanations for paronymous expressions derived from matter: on the received picture, derived from Metaphysics Θ.7, such expressions are used in all and only cases of substantial change, because predicating the matter directly of a substance would be false; on the error picture, derived from Metaphysics Z.7, the same expressions are used in all and only cases of change from an unclear and nameless privation, because ordinary language users conflate such privations with matter. I propose a resolution: (...) the received picture explains why the usage is fitting, but the error picture explains how the usage originated. (shrink)

This major new study of Aristotle's natural philosophy connects it to modern theories of causation and provides fresh interpretations of classic issues. Structured around close readings of the Physics and the Metaphysics and informed by contemporary theories of causation, it offers a rich treatment of some of Aristotle's core texts.

Aristotle’s Meteorology 4.12 is puzzling, in part because the chapter appears to extend teleological explanation to include certain inorganic materials without natural biological functions, such as metals and stone. This paper examines two attempts to explain why such materials can have functions, and shows that they are problematic. As an alternative, I argue that raw inorganic materials—as well as separated parts of organisms—can have extrinsic functions. Extrinsic functions can explain why natural inorganic materials can be sorted into natural kinds, even (...) if their functions are ultimately related to their uses in the productive arts. (shrink)

I present a problem concerning the predication of elemental qualities in Aristotle’s On Generation and Corruption: What is the subject of predication for the elemental qualities? The usual answer in the scholarship is either the elements themselves, or prime matter (traditionally conceived). I argue that neither can perform this role. Instead, I explore the possibility that the elemental qualities are individually predicated of their own material principle. I show that this solution fits the text and solves the problem of predication (...) of elemental qualities. I conclude by offering some comments on the status of the elemental contraries and demonstrate the benefits of my view in conjunction with some recent scholarship on the elemental contraries.

Ethics for Rational Animals brings to light a novel account of akrasia, practical wisdom, and character virtue through an original and comprehensive study of the moral psychology at the basis of Aristotle's ethics. It argues that practical wisdom is a persuasive rational excellence, that virtue is a listening excellence, and that the ignorance involved in akrasia is in fact a failure of persuasion. Aristotle's moral psychology emerges from this reconstruction as a qualified intellectualism. The view is intellectualistic because it describes (...) practical wisdom as the sort of knowledge that can govern desire and action and akrasia as involving a form of ignorance. However, Aristotle's intellectualism is qualified because practical wisdom goes beyond grasping the truth about the human good, for it must also be able to convey the truth persuasively to non-rational cognition and desires.

As in the case of other humanists and philosophers of the period, an important aspect of Pico della Mirandola's interpretation of the Platonic Timaeus consists of direct access to the dialogue in its original Greek, which the young man possessed in his personal library. This does not mean that Pico does not also take an interest in the ancient Latin translations of Cicero and Calcidius, both personally and in Ficino's circle. But these are read with the critical distance and the (...) historical and philological rigour of the period. Plato's cosmology, his theory of first principles, of the structure of the cosmos and of human nature, are read by Pico in dialogue, in contrast and in hidden coincidence with the Aristotelian system of the universe, but also alongside the conceptions of the world and of humankind of other Jewish, Christian, Neoplatonic, Arabic, Hermetic and Kabbalistic authors and texts. Demonstrating the confluence of all these systems with biblical revelation is particularly pressing for Pico, who knows himself to be the heir of the Greek and Latin patristic authors. Nevertheless, the pagan philosophical tradition occupies a privileged place in the exegetical lenses of Pico, who has recourse on countless occasions to the Commentary on the Timaeus of Proclus and to the exegeses of Plutarch, Porphyry, Iamblichus, Emperor Julian and Simplicius, not forgetting the allegedly ancient Pythagorean Timaeus of Locri and Ocellus Lucanus. The chapter offers, in addition to an introduction to Pico's figure and oeuvre, an analysis of his reception of the Timaeus and a trilingual edition (Latin-Spanish, Tuscan-Spanish) with some of the central passages of his works.

The Catena aurea entium of Henry of Herford is part of the work of re-elaboration of Aristotle’s natural-philosophical corpus, which characterised the European intellectual environment in the Late Middle Ages. In the central books of his encyclopaedia, Henry comments on the works of natural philosophy of Albert the Great, placing himself in continuity with the cultural project started by Albert in Cologne. The present article aims to compare the 5th book of the Catena aurea entium, which consists of a comment (...) per modum quaestionis on the Meteora of Albert the Great, with some meteorological quaestiones composed between the 13th and 15th centuries. This analysis will lead me to grasp the philosophical orientations and interpretation of Henry and also his reception of Albert the Great’s meteorology. In the 5th book, Henry introduces an extensive medical section taken from the pseudo-Aristotelian Problemata, in which he applies the Galenic medical principles to meteorology. Besides, in the quaestio 105 (V 1 105), he interprets Albert through the theological-poetic explanation of ancient origins on the sacrality of the number three and an excerpt from the Liber proverbiorum.

A puzzle about the presentation of objects located at a distance is seen to animate Aristotle's account of transparency in De Anima and De Sensu.

Aristotle’s biology is based on his method of division of animal kinds by multiple differentiae. This results in complex clusters of non-subordinate terms, between which Aristotle seeks to establish universal correlations. The form of these, however, does not correspond to that prescribed by his theory of syllogism. Mereological relations between terms are not linear and quantification is far more complex than the distinction between universal and particular propositions. Thus the axiomatisation of Aristotle’s biology requires a tool designed for analysing such (...) complex universal correlations into valid syllogistic premises. Prosleptic-like premises turn out to be the solution outlined by Aristotle. They make it possible to handle both the logic of consequence which translates from and into mereological relations between term clusters, and the complex quantification required by division based on multiple differentiæ, through the instantiation of a variable ideally consisting of indivisible groups of animals.

In this paper, I argue that Aristotle was already aware in his earlier texts of the fundamental distinction between motion and activity and of the criterion which structures this contrast. Moreover, I will present textual evidence which suggests that Aristotle’s original concept of ἐνέργεια applies primarily to activities which contain their ends in themselves, and not to motions, which are different from their ends.

Whereas scholars often look to De Anima 2.5 to support one or another understanding of the sense in which perception, for Aristotle, qualifies as an alteration and qualitative assimilation to the sense-object, I ask the more basic question of what the chapter is meant to establish or accomplish with respect to the question whether perception is an alteration. I argue that the chapter does not presuppose or legitimate the view that perception is an alteration where it is thought to, and (...) that it is meant rather to challenge that view, most importantly, by putting its argumentative weight behind a different model of perception, leading to a kind of antinomy. What stands in the way of understanding perception as an alteration (and assimilation to the sense-object), in this chapter, is ultimately the lack of an account of perceiving a quality as having that quality.

In this essay, I respond to a problem raised by Sarah Broadie in her 1987 article “Nature, Craft and Phronesis in Aristotle.” Broadie analyzes Aristotle’s famous craft analogy for natural causation in order to determine whether or not it requires importing a psychological dimension to natural teleology. She argues that it is possible to make sense of the analogy without psychology, but that the tradeoff is a conception of craft so thoroughly de-psychologized that it is rendered unrecognizable, perhaps even incoherent (...) as a referent. I dispute this suggestion and argue, rather, that Aristotle’s insistence on removing psychology from the craft side of the analogy points to his prioritization of techne itself, rather than any particular craftsman, as primary efficient agent. The lack of psychology that characterizes a techne ensures stability and reliability in the causal process that could not be guaranteed by the idiosyncratic psychologies of various craftspeople. The same kind of stability and reliability belong to nature as an efficient cause, forming the basis of the comparison between craft and natural teleology. It is therefore the craft, not the craftsman, that must stand as analog to nature. I demonstrate the value of this revision by applying the analogy to the case of natural teleology: reproduction as depicted in Aristotle’s Generation of Animals. The result is a reading of Aristotle’s analogies that can assuage Broadie’s concerns and allow for a natural thing’s own nature to more fully inhabit its intended role as an inner source of change.

This paper makes some additional points about matters discussed in my book „Aristoteles als Naturwissenschaftler“ (Aristotle as a Natural Scientist), Berlin 2014. Findings by the biologist A. M. Leroi, who published a book on Aristotle with a similar subject that same year („The Lagoon. How Aristotle invented science“), will be considered. It will be argued that the mayflies discovered by Aristotle in the Kuban River belong to the species Palingenia fuliginosa. Aristotle is more likely to have observed the life-history of (...) the catfish in the river Strymon in Northern Greece than in the Achelous river basin in Acarnania. He probably never set eyes on the catfish Silurus aristotelis, which is endemic to Acarnania and was discovered by Agassiz in 1857. (shrink)

While Aristotle provides the crucial testimonies for the paradoxes of motion, topos, and the falling millet seed, surprisingly he shows almost no interest in the paradoxes of plurality. For Plato, by contrast, the plurality paradoxes seem to be the central paradoxes of Zeno and Simplicius is our primary source for those. This paper investigates why the plurality paradoxes are not examined by Aristotle and argues that a close look at the context in which Aristotle discusses Zeno holds the answer to (...) this question.

In his contemplative works on nature, Aristotle twice appeals to the general principle that being is better than not being. Taking his cue from this claim, Christopher V. Mirus offers an extended, systematic account of how Aristotle understands being itself to be good. Mirus begins with the human, examining Aristotle's well-known claim that the end of a human life is the good of the human substance as such--which turns out to be the good of the human capacity for thought. Human (...) thought, however, is not concerned with human affairs alone. It is also contemplative, and contemplation is oriented toward the beauty of its objects. In each of the three branches of contemplative thought--mathematics, natural science, and theology--the intelligibility of being renders it beautiful to thought. Both in nature and in human life, moreover, the being that is beautiful through its intelligibility serves also as an end of motion and of action; hence it counts not only as beautiful, but also as good. The persistent concern of thought with the beautiful reveals what is at stake for human beings in Aristotle's larger metaphysics of the good: in the connection between goodness and actuality that structures his natural science and metaphysics, in his explicit claim that being is better than not being, and in his concepts of order and determinacy, which help connect being with goodness. These in turn shed light on his concepts of the complete and the self-sufficient, on his teleological understanding of the four elements, and on the curious role of the honorable in his natural science and metaphysics.

Aristotle’s theory of seed has occupied a very important place in the history of ancient embryology and medicine. Previous studies have overemphasized, in light of the APo. II method, Aristotle’s definition of seed as male semen. In this paper, I wish to show that there are at least three independent definitions of seed working in Aristotle’s Generation of Animals: seed as male semen, seed as female menstruation and seed as embryo. Those three definitions are mutually exclusive on the one hand, (...) but on the other hand, they are also capable of being unified into one Aristotelian account, which can help us understand better Aristotle’s theory of seed.

Thomas Nagel argues that Aristotle identifies rationality as the ergon idion of the human being. Against Nagel, I defend a reading of Aristotle which depicts a complex human ergon. This complex identity involves desire. It is in Book X of the Nichomachean Ethics that my understanding of Aristotle's position is clinched.

I reconstruct Aristotle’s explanation for why and how birds are capable of natural flight. For Aristotle, air is a markedly different external resting point in comparison with water and earth, and nature has designed birds so as to take advantage of the unique way in which air affects the inequality between the pushing downward, that is, the downward force and the resistance. My discussion sheds some light on Aristotle’s anticipation of some aspects of modern fluid dynamics and aerodynamics.

This brief article aims to supplement Stefan Schnieders's presentation of the evidence for Historia animalium 7—that is, Book 7 according to the manuscript tradition, Book 8 according to Theodore Gaza's rearrangement—having been considered the seventh book of this work in antiquity. This is accomplished through the discussion of two texts not considered by Schnieders, both of them passages commenting on Iliad Book 21: P.Oxy. 221 and Porphyry, Homeric Questions Book 1.

Few ideas are more central to Aristotle’s thought than that of the causal purposiveness of natural things. Few ideas in the Aristotelian corpus are more controverted—whether historically, by early modern natural philosophers seeking to break with Aristotelian science or currently, by modern scholars of ancient philosophy seeking to interpret Aristotle’s physics—than what has come to be called Aristotle’s “teleology” (a term coined in the 18th century, apparently by the German philosopher Christian Wolff). In this ambitious study (derived from the author’s (...) 2003 doctoral dissertation at the University of Toronto), Monte Johnson [J.] aims at two goals: to determine both how Aristotle uses the notions of “ends” or purposes in his natural philosophy and what are the limits to Aristotle’s teleological explanations.

Aristotle (384-322 B.C), a well know Greek philosopher, physician, scientist and politician. A variety of identifying researches have been written on him. It is therefore a considerable pride for the researcher to write something about him when even mentioning his name and his father's name is a point of prestige in the Greek Language. His name means the preferable sublimity whereas Nicomachus (his father's name) means the definable negotiator. His father's and mother's origin belongs to Asclepiade, the favorite origin in (...) Greek. Points of view regarding this figure are controversial some praise him and consider him the peak of philosophical thinker which makes humanity in general owe this genius thinker a great deal. Others believe that the effect of his thought on humanity is the reason behind the non-progress of science. Whatever ones opinion is, his thoughts have a wonderful force in stimulating and positively affecting the people's thinking. His philosophy is the greatest philosophy which the world has ever witnessed or which may ever witness., if it couldn’t solve some of the problems of philosophy, it at least, makes the world more rational than before. He is the founder of the philosophical language in describing a large number of philosophical terms which are still in use nowadays. Moreover his books and platonic dialogues are considered encyclopedias in providing a basis for philosophy even before Socrates. For theses among other reasons, I am choosing Aristotle as a subject for research and concentrating on natural philosophy. The critical side deals with the criticism of natural philosophers. In order to fully understand Aristotle, we should understand his predecessors. Their virtue is undeniable. Without them, Aristotle's and Plato's genius would never be in this ideal shape. In addition to that, they are philosophers and scientists who mixes between science, philosophy, morality and politics in a complementary form. They are a source of illumination to the human thinking in general. Without them humanity could never have got rid of mythology. This is the code of life, for many generations should pass before the rare genius could attain a prominent idea. When Tales formulates the philosophical question, where does the world come from? This is a decisive moment in human thinking similar to the coming moments, the one Parmenides, and Protagoras statement: man is the norm for all things. Pre-Socrates philosophers are all considered glowing points in drawing Aristotle's philosophy. Thus my book is entitles (Aristotle's criticism of Pre-Socratic Natural Philosophy) which means the concentration on the critical operation through which the natural side of the previous philosophers appears. The nature of the title forces me to deal with Aristotle's ideas from every point of view. Thus the book proceeds according to structure and criticism and the construction of Aristotle's philosophy. Because the title is comprehensive and limited simultaneously, I have chosen the critical subjects in the lights of the natural philosophy. I have divided the book into four chapters with fourteen sections in addition to the implemented parts included in every section purporting to cover every part of criticism looking for comprehensiveness. I have found it obligatory to mention something about Aristotle's view in criticism, in addition to a precise delimitation of nature and its subjects. This is the subject of the first chapter. The second chapter deals with the principles of natural body, i.e., the principles dealt with pre-Aristotle philosophy and then these three principles (Hyle, form ,and Non-being). After delaminating these sides, it is possible to deal with the details (Movement, Place, Time, Vacuum and Infinite) which are natural concepts for the third chapter. As a complementation to the natural sides, the chapter four deals with two topics , Universal and corruption, and theory of elements. This book, in my own opinion, is comprehensive to the majority of natural philosophers and it focuses on the argument of Aristotle's criticism to the views of natural philosophers before Socrates together with the discussion of the Aristotelian alternative from these points of view. Aristotle sometimes tends to praise the previous philosophers. This does not mean the non-conformity between what he wants to say and what they described. When he, for example, says that the previous philosophers realized the material defect in Thales idea that water is the origin of all things but Thales’ water is not like Aristotle's Hyle, it is completely different thing. Finally I have viewed the index of Arab Library, and was unable to trace a book which is especially oriented in this subject i.e. writings on Aristotle's criticism to natural philosophy before Socrates. Therefore I have been stimulated to write about a very new subject. This subject fills a gap in Arab studies. (shrink)

William Gilbert’s 1600 book, De magnete, greatly influenced early modern natural philosophy. The book describes an impressive array of physical experiments, but it also advances a metaphysical view at odds with the soon to emerge mechanical philosophy. That view was animism. I distinguish two kinds of animism – Aristotelian and Platonic – and argue that Gilbert was an Aristotelian animist. Taking Robert Boyle as an example, I then show that early modern arguments against animism were often effective only against Platonic (...) animism. In fact, unacknowledged traces of Aristotelian animism can be found in Boyle’s mechanical account of nature. This was Gilbert’s legacy. (shrink)

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 “out of which” cause : the material is the cause out of which an artifact is made. Next, I examine Physics II 7, a chapter in which Aristotle names "the material" as one of the four kinds of cause in its own right. But Aristotle’s model of "the material" remains the material out of which an artifact is made. (shrink)

On Zeno Beach there are infinitely many grains of sand, each half the size of the last. Supposing Aristotle denied the possibility of Zeno Beach, did he have a good argument for the denial? Three arguments, each of ancient origin, are examined: the beach would be infinitely large; the beach would be impossible to walk across; the beach would contain a part equal to the whole, whereas parts must be lesser. It is attempted to show that none of these arguments (...) was Aristotle’s. Indeed, perhaps Aristotle’s finitism applied to magnitude only, not plurality. (shrink)

In Metaphysics Λ.6-7 Aristotle argues that an unmoved substance causes the outermost sphere to rotate. His argument has puzzled and divided commentators from ancient Greece to the present. I offer a novel defense of Aristotle's argument by highlighting the logic of classification that Aristotle deploys. The core of Aristotle's argument is the identification of the unmoved substance on the 'table of opposites' as simple and purely actual. With this identification in place, Aristotle argues that the outermost sphere activates its capacity (...) to relocate its body by rotating because this is how it can be a simple and actual substance. But unlike traditional attempts to rehabilitate Aristotle's argument, I argue that the sphere does not rotate in order to imitate the Prime Mover. Rather, the sphere rotates because that is good for it to do, and the Prime Mover is a metaphysically necessary source of simple and actual substantial being, which the sphere acts for the sake of.

I explain what Aristotle means when, after puzzling about the matter of motion in incomplete animals (those without sight, smell, hearing), he suggests in De Anima III 11.433b31–434a5 that just as incomplete animals are moved indeterminately, desire and phantasia are present in those animals, but present indeterminately. I argue that self-motion and its directing faculties in incomplete animals differ in degree but not in kind from those of complete animals. I examine how an object of desire differs for an incomplete (...) animal. Using a comparison with Aristotle’s account of recollection, especially in unfavorable circumstances, I describe indeterminate self-motion. Finally, I discuss implications for our understanding of Aristotle’s accounts of the faculties of the soul and incomplete animals. (shrink)

This paper argues that focusing on Aristotle’s theory of generation as primarily ‘hylomorphic’ can lead to difficulties. This is especially evident when interpreting the association between the male and sentient soul at GA 2.5. If the focus is on the male’s contribution as form and the female’s as matter, then soul becomes divided into nutritive from female and sentient from male which makes little sense in Aristotle’s biological ontology. In contrast, by seeing Aristotle’s theory as ‘archēkinētic’, a process initiated by (...) the male, the development of nutritive and sentient capacities emerges as intertwined, neither capacity originating in only one sex.

Once upon a time in the twentieth century, it was considered good sense by some to think that Aristotle began his De anima with a series of very Aristotelian theories about the soul, and that the function of its first book was to eristically taunt his predecessors for failing to appreciate hylomorphism, or patronizingly praise them for getting the odd bit right. Jason Carter deserves our thanks for showing how wrong-headed this reading of Aristotle is. His book begins with the (...) much more sensible assumption that the review of previous δόξαι in DA I plays an important and even constitutive role for theses at the core of Aristotle's theory of soul and living things, prominent among them these two: that the soul...

In a recent book, Substance and the Fundamentality of the Familiar, Ross Inman demonstrates the contemporary relevance of an Aristotelian approach to metaphysics and the philosophy of nature. Inman successfully applies the Aristotelian framework to a number of outstanding problems in metaphysics, philosophy of mind, and the philosophy of physics. Inman tackles some intriguing questions about the ontological status of proper parts, questions which constitute a central focus of ongoing debate and investigation.

Aristotle is said to have held that any kind of actual infinity is impossible. I argue that he was a finitist (or "potentialist") about _magnitude_, but not about _plurality_. He did not deny that there are, or can be, infinitely many things in actuality. If this is right, then it has implications for Aristotle's views about the metaphysics of parts and points.
