Although Aristotle's contribution to biology has long been recognized, there are many philosophers and historians of science who still hold that he was the great delayer of natural science, calling him the man who held up the Scientific Revolution by two thousand years. They argue that Aristotle never considered the nature of matter as such or the changes that perceptible objects undergo simply as physical objects; he only thought about the many different, specific natures found in perceptible objects. Against this (...) view, this book argues that Aristotle offers a systematic account of matter, motion, and the basic causal powers found in all physical objects. It argues that Aristotle not only sees all perceptible objects as sharing certain basic physical properties, but he also holds that perceptible objects have these physical properties because they are ultimately made from physical matter of one kind or another. Finally, it argues that for Aristotle the basic properties of matter, including the basic properties of the material elements, cannot be understood teleologically. (shrink)

Seventeenth-century advancements in physical science are often presented as overthrowing the Aristotelian tradition; perhaps Aristotle's emphasis on formal and final causes left little room for a physical theory grounded in material and efficient causes. In Aristotle's Science of Matter and Motion, Christopher Byrne argues that Aristotle is not to blame, as he indeed possessed a unified theory of matter and motion. In contrast to traditional interpretations, which place an undue explanatory burden on formal and final causes, Byrne argues that (...) Aristotle's theory of the physical world is dependent on the features possessed by perceptible objects, qua perceptible, as well as non-teleological changes in matter.Byrne's... (shrink)

It is often claimed that Socrates rejects material causes in the Phaedo because they are not rational or not teleological. In this paper I argue for a new account: Socrates ultimately rejects material causes because he is committed to each change having a single cause. Because each change has a single cause, this cause must, on its own, provide an adequate explanation for the change. Material causes cannot provide an adequate explanation on their own and so Socrates (...) rejects them. Aristotle agrees that material causes cannot explain changes on their own, but by allowing the same change to have multiple causes, he makes room for a material cause. Aristotle draws attention to the anti-Platonic implications of his four causes in a passage in Physics II.3 (195a3- 14) that has been overlooked by commentators. (shrink)

In the first two books of the Physics Aristotle discusses philosophical issues involved in the investigation of the physical universe. He introduces his distinction between form and matter and his fourfold classification of causes or explanatory factors, and defends teleological explanation. These books therefore form a natural entry into Aristotle's system as a whole, and also occupy an important place in the history of scientific thought. The present volume provides a close literal translation, which can be used by serious students (...) without Greek. The introduction and commentary deal with the interpretation and assessment, from a philosophical standpoint, of what Aristotle says. This translation was first published in 1970. (shrink)

Aristotle uses two kinds of material cause in his analysis of biological organisms: compositional matter, which persists through their birth and death;and functional matter, which consists of the organs and functional parts out of which biological organisms are made while they are alive. These two kinds of material cause, it has been argued, have quite different explanatory roles: functional matter is required by biological organisms to perform their essential functions,but compositional matter contributes nothing necessary to them and is (...) only responsible for their accidental properties. Against this view, I argue that biological organisms are systematically dependent upon their compositional matter and the latter is responsible for many of their necessary attributes. (shrink)

This book examines Aristotle's four causes (material, formal, efficient, and final), offering a systematic discussion of the relation between form and matter, causation, taxonomy, and teleology. The overall aim is to show that the four causes form a system, so that the form of a natural thing relates to its matter as the final cause of a natural process relates to its efficient cause. Aristotle's Four Causes reaches two novel and distinctive conclusions. The first is that the formal (...) cause or essence of a natural thing is not a property of this thing but a generic natural thing. The second is that the final cause of a process is not its purpose but the course that processes of its kind typically take. (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)

In his metaphysics and natural philosophy, Aristotle uses the concept of a material cause,i.e., that from which something can be made or generated. This paper argues that Aristotle also has a concept of matter in the sense of physical stuff. Aristotle develops this concept of matter in the course of investigating the material causes of perceptible substances. Because of the requirements for change, locomotion, and the physical interaction of material objects, Aristotle holds that all perceptible substances (...) must be extended in three dimensions, movable, and corporeal due to their material causes. Thus, perceptible substances are physical substances because they are made out of something physical. (shrink)

In Aristotle’s physics and biology, matter’s capacity for spontaneous, opaque, chance deviation is named by automaton and marked with a feminine sign, while at the same time these mysterious motions are articulated, rendered knowable and predictable via the figure of ta automata, the automatic puppets. This paper traces how automaton functions in the Aristotelian text as a symptomatic crossing-point, an uncanny and chiasmatic figure in which materiality and logos, phusis, and technē, death and life, masculine and feminine, are intertwined and (...) articulated. Automaton permits a mastery of generative materiality for teleological metaphysics, but also works to unsettle teleology’s systematic and unifying aspirations. (shrink)

Aristotle presents four causes in Posterior Analytics 2.11, but where we expect matter we find instead the confusing formula, ‘what things being the case, necessarily this is the case’, and an equally confusing example. Some commentators infer that Aristotle is not referring to matter, others that he is but in a non-standard way. I argue that APo. 94a20-34 presents not matter, but determination by general features or facts, including facts about something’s genus. The closest connection to matter is Aristotle’s view (...) that the relation between genus and species is analogous to that between matter and a hylomorphic compound. (shrink)

Book synopsis: Aristotle's probing inquiry into some of the fundamental problems of philosophy, The Metaphysics is one of the classical Greek foundation-stones of western thought, translated from the with an introduction by Hugh Lawson-Tancred in Penguin Classics. The Metaphysics presents Aristotle's mature rejection of both the Platonic theory that what we perceive is just a pale reflection of reality and the hard-headed view that all processes are ultimately material. He argued instead that the reality or substance of things lies (...) in their concrete forms, and in so doing he probed some of the deepest questions of philosophy: What is existence? How is change possible? And are there certain things that must exist for anything else to exist at all? The seminal notions discussed in The Metaphysics - of 'substance' and associated concepts of matter and form, essence and accident, potentiality and actuality - have had a profound and enduring influence, and laid the foundations for one of the central branches of Western philosophy. Hugh Lawson-Tancred's lucid translation is accompanied by a stimulating introduction in which he highlights the central themes of one of philosophy's supreme masterpieces. Aristotle (384-22 BC) studied at the Academy of Plato for 20 years and then established his own school and research institute, 'The Lyceum'. His writings, which were of extraordinary range, profoundly affected the whole course of ancient and medieval philosophy and are still eagerly studied and debated by philosophers today. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 49-75 [Access article in PDF] Sensible Ends:Latent Teleology in Descartes' Account of Sensation Alison Simmons One of Descartes' hallmark contributions to natural philosophy is his denunciation of teleology. It is puzzling, then, to find him arguing in Meditation VI that human beings have sensations in order to preserve the union of mind and body (AT VII 83). 1 This (...) appears to be just the sort of teleological explanation that he proscribes. Descartes' Anglo-American commentators have had little to say about the teleological overtones of his claims about sensation. His French commentators acknowledge these overtones, but seem largely untroubled by them. 2 It is worth pausing to be troubled, for a closer analysis reveals that Descartes' famous proscription against teleology is not as simple as it is generally thought to be. In the first half of this essay, I argue that Descartes advocates a genuinely teleological conception of the senses. My aim is not to charge Descartes with employing illicit teleology, but to argue that there is a place for teleology even in his revisionist natural philosophy. Accordingly, in the second half of this essay, I argue that Descartes' assault on teleological explanation is [End Page 49] not a sweeping assault on finality, but a more directed attack on particular uses of ends in natural philosophy. Descartes' assault leaves standing a form of teleological explanation that proves crucial to his own treatment of sensation. 1. Descartes' Rejection of Teleological Explanation at a Glance A teleological explanation is one that purports to account for something in terms of its ends or its function relative to the ends of the system of which it is a part. Aristotle's physics provides many classic examples: plants produce leaves for the protection of their fruit; spiders spin webs in order to catch food; animals grow sharp front teeth and dull back teeth in order to facilitate biting and chewing respectively; eyes are for seeing. According to Aristotle, all natural phenomena are directed toward ends and no explanation is complete without a teleological component that specifies the end for the sake of which the phenomenon occurs. Indeed ends take explanatory priorityover other causes: "Both causes [the end and the matter] must be stated by the student of nature, but especially the end; for that is the cause of the matter, not vice versa." 3 And: [T]he causes concerned in natural generation are, as we see, more than one. There is the cause for the sake of which [the end], and the cause whence the beginning of motion comes [the efficient cause]. Now we must decide which of these two causes comes first, which second. Plainly, however, that cause is the first which we call that for the sake of which. For this is the account of the thing, and the account forms the starting-point.4In other words, Aristotle argues that natural substances have the matter they do, have the parts or organs they do, are organized as they are and act as they do for the sake of their ends. To explain why things are as they are, the natural philosopher must therefore explain the ways in which they contribute to ends.Among the late scholastic Aristotelians familiar to Descartes there is considerable debate concerning the causal efficacy of ends. Genuine final causation, in which something is said to be acted on by an end, is limited to the intentional behavior of rational agents who consciously recognize their ends: only something that recognizes an end can be "moved" by one. Even here the sort of causation involved is peculiar: a rational agent is "moved" by an end insofar as the end induces a "metaphorical motion" toward (or desire for) the end in the agent's will. 5 While these scholastic Aristotelians resist attributing final causation [End Page 50] to non-rational creatures, they nevertheless persist in attributing ends to them. When Toletus, Rubio, the Coimbrans and Suarez take up the question whether nature acts propter finem, each answers it affirmatively: natural... (shrink)

This is partly a book about Aristotle’s four causes (material, formal, efficient, and final cause), partly a systematic discussion of the relation between form and matter, causation, and teleology. Its overall aim is to show that the four causes form a system, so that the form of a natural thing relates to its matter as the final cause of a natural process relates to its efficient cause. It reaches two highly distinctive conclusions. The first is that the formal (...) cause or essence of a thing is not a property but a generic thing. The second is that the final cause of a process is not its purpose but the course that processes of its kind typically take. (shrink)

The notes interpret Aristotle's arguments and discuss his views on major issues such as natural teleology. The original edition was (...) published in 1972. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Matter and Mathematics: An Essentialist Account of the Laws of Nature by Andrew YOUNANDominic V. CassellaYOUNAN, Andrew. Matter and Mathematics: An Essentialist Account of the Laws of Nature. Washington, D.C.: The Catholic University of America Press, 2023. xii + 228 pp. Cloth, $75.00Andrew Younan’s work situates itself between two opposing philosophical accounts of the laws of nature. In one corner, there are the Humeans (or Nominalists); in the (...) other, the Anti-Humeans (or Platonists). The goal of the book is to find an explanation for the orderliness of the natural world that avoids falling into the difficulties of the two opposing philosophies. For example, the Humeans treat “events” as fundamental, and the laws of nature follow from these “events.” For the Humeans, reality is essentially random, with any order being something of our own contrivance. Whereas for the Anti-Humeans, the laws of nature are fundamental and are treated as causing events, turning the effect of necessity into the cause of material [End Page 166] characteristics. Looking to Aristotle and Thomas Aquinas, Younan proposes the recovery of a third option, the Essentialist position. This Essentialist position understands substances, that is, individual beings, as fundamental and all else (for example, events and laws of nature) follow from these individual beings. The thesis of the book, generally understood, is that Essentialism evades the critiques that the Humeans and Anti-Humeans put against one another while retaining what is right in each approach.The book is divided into two parts. The book’s first part deals with general objections and replies and is divided into three chapters. Chapters 1 and 2 address the two opposing accounts of nature mentioned, while chapter 3 argues for the benefits of recovering an Essentialist position. Chapter 1 examines the objection that Aristotelian natural philosophy is incompatible with modern science, an objection raised by Descartes. Chapter 2 addresses the objections of the Humeans, namely, that natural philosophy and, with it, causality and induction have been debunked. Chapter 3 looks at the fathers of quantum theory, specifically Heisenberg, and argues that a return to Aristotle’s understanding of nature would benefit the modern scientific project. The book’s second part is an argument for the Essentialist position and is divided into three chapters. Chapters 4 and 5 are the foundation for chapter 6. Chapter 4 is an abstractive account of mathematics, differing from Descartes and his conceptions, which draws on the texts of Aristotle and Aquinas’s Division and Methods. Chapter 5 situates necessity and its role in Aristotelian natural philosophy. Chapter 6 is the author’s attempt at defining what it is to be a law of nature.Younan argues that adopting an essentialist understanding of nature in a system where all knowledge begins in the senses has three significant “payoffs.” The first is that it avoids governance language, that is, it avoids making laws themselves causes of necessity; the second is that it avoids the assertion of a priori knowledge; the third is that it understands individual things as the fundamental primitives in nature, restoring the substance to its proper place as the thing that “stands under” accidental being.The book is concluded with an appendix that explores and rearticulates Thomas Aquinas’s fifth way under the consideration of everything the author had argued for in the book’s main text. Taking as established by the rest of the book that necessity and teleology go hand in hand, Younan argues for a creator God who establishes a universe freely but within certain parameters that follow upon being itself. Younan concludes, with Thomas Aquinas, that laws of nature are “ordinances of reason” that must come from a rational mind. To be as consistent as they are, the laws of nature must be promulgated by God, and they are discoverable within the nature of matter itself.Younan’s book often engages its interlocutors on the big-picture scale, frequently giving generalizations and not going into details to avoid getting bogged down in the weeds. The author is very aware of what he is doing. [End Page 167] It is appropriate since engaging the multiheaded hydra of the schools of thought that Younan... (shrink)

Some commentators have argued that there is no room in Aristotle's natural science for simple, or unconditional, physical necessity, for the only necessity that governs all natural substances is hypothetical and teleological. Against this view I argue that, according to Aristotle, there are two types of unconditional physical necessity at work in the material elements, the one teleological, governing their natural motions, and the other non-teleological, governing their physical interaction. I argue as well that these two types of simple (...) necessity also govern everything made out of the elements, that is, all other natural substances and artifacts. (shrink)

Aristotle's doctrine of the four causes--formal, final, efficient and material--is famous. But Posterior Analytics B 11 lists "if certain things hold, it is necessary that this does" in place of a standard expression for the material cause. This cause has been dubbed the grounding cause. It has interested scholars since the Greek commentators, who simply assumed that Aristotle meant the material cause. This traditional thesis has been challenged by two views: first, that the grounding cause is a (...) special type of material cause ; second, that it is no material cause at all . ;I set out two arguments for the traditional thesis and consider nine objections to it. Since most of these objections, which constitute the support for the revisionist thesis, can be answered, I reject the revisionist thesis. But in my treatment of one objection it also becomes clear that the traditional thesis is mistaken. The grounding cause is a necessitating cause, yet in Physics B 9 Aristotle makes it clear that many material causes are not necessitating causes. Thus, some form of the modified traditional thesis is true. ;But which form? D. M. Balme suggests that Aristotle means to include only mathematical causes because hypothetical necessity covers all of the relation between matter and product in things which come to be. But Aristotle seems to accept necessitating material causes in several passages in the biological works. In other passages he seems to adopt the position Balme attributes to him. I argue that he does not actually adopt this position, and that he does accept simple necessity in some things which come to be. Thus, the grounding cause is a necessitating material cause, and such causes are found not only in mathematics, but also among things which come to be. (shrink)

In Meta. Λ 8, Aristotle argues that the heaven –and, thus, the cosmos – is numerically unique on the grounds that its first unmoved mover is numerically unique. The latter is numerically unique because it is ‘essence’ and does not have matter. “But whatever is many in number has matter.” I refer to this inference as Aristotle’s metaphysical argument for the uniqueness of the cosmos. A problem arises: If the subsidiary unmoved movers of the planetary spheres are, like the prime (...) unmoved mover, immaterial substances and belong to the same species of unmoved mover, it seems that they could not be numerically distinct from that first unmoved mover – while Aristotle maintains that they are, in fact, numerically distinct. That is, as immaterial substance, it/they could not be individuated by matter. However, if they do, as souls or soul-like forms, inform matter, it seems that there is no reason why the first unmoved mover, which moves the sphere of fixed stars or outermost, celestial sphere, should not similarly inform the matter of that celestial sphere. In the latter case, Aristotle’s argument for the uniqueness of the heaven and cosmos would be vitiated. The first unmoved mover would be the form of the outermost celestial sphere; and there would evidently be no metaphysical reason why that form could not be materially instantiated by other outermost celestial spheres, each enclosing its own cosmos distinct from our own. I argue that neither of the two salient options for resolving this problem with Aristotle’s metaphysical argument for the uniqueness of the cosmos is satisfactory. The result, so I maintain, is Aristotle’s diremption of divinity into two essentially unrelated aspects: divinity as autonomous, ‘hermetic’ cognition and divinity as ultimate cause of cosmic motion and change.

Aristotle is commonly considered the inventor of teleology, although the exact term "teleology" originated in the eighteenth century. If teleology means the use of ends and goals in natural science, then Aristotle should be regarded rather as a critical innovator of teleological explanation. Teleological notions were widespread among his predecessors, but Aristotle rejected their conception of extrinsic causes like mind or god as the primary causes for natural things. Aristotle's radical alternative was to assert nature itself as (...) an internal principle of change and an end, and his teleological explanations focus on the intrinsic ends of natural substances---those ends that benefit the natural thing itself. To these he contrasted incidental ends of natural things, such as possible uses of the thing which do not serve its own functions and interests. ;Aristotle holds that natural science is knowledge that comes about through demonstration of the causes of natural kinds. Most important is "the cause for the sake of which"---the end. The identification of a natural end initiates the process of explanation and constitutes the basis for all objective knowledge about natural kinds---stars, elements, plants, and animals. The determination of the ends of natural kinds also indicates how other causal factors, such as matter and necessity, are to be integrated into an explanatory account of their parts and behavior. ;Aristotle's teleology was subsequently conflated with incompatible "teleological" notions, including proofs for the existence of a providential or designer god, vitalism and animism, opposition to mechanism and non-teleological causation, and anthropocentrism. I aim to correct these misrepresentations through an investigation of Aristotle's methodological statements, as well as the explanations actually offered in the scientific works. I argue that Aristotle's aporetic approach avoids the dilemma between backwards causation and anthropomorphism that is frequently leveled against teleology. ;Although Aristotle's philosophy sometimes suffers from failed extrapolation of teleological principles, still it succeeds in challenging the anthropocentric conception of nature, and rising above the banausic perspective which views all natural things as instruments for human ends, to a loftier viewpoint from which natures can be observed and appreciated as their own goods.

Teleology is the study of ends and goals, things whose existence or occurrence is purposive. Aristotle’s views on teleology are of seminal importance, particularly his views regarding biological functions or purposes. This article surveys core examples of Aristotle’s invocations of teleology; explores philosophically puzzling aspects of teleology (including their normativity and the fact that ends can, apparently, act as causes despite never coming to exist); articulates two of Aristotle’s arguments defending commitment to teleology against critics (...) who attempt to explain nature solely through appeal to nonteleological efficient and material causes; and argues that Aristotle was an ontological realist when it came to teleology: he conceived of ends as an irreducible and ineliminable aspect of the causal structure of reality. Other interpretive controversies are addressed more briefly. (shrink)

In the De Generatione et Corruptione II 9, Aristotle aims to achieve the confirmation of his theory of the necessity of the efficient cause. In this chapter he sets out his criticism on the one hand of those who wrongly attributed the efficient cause to other kinds of causality and on the other, of those who ignored the efficient cause. More specifically Aristotle divides all preceding theories which attempted to explain generation and corruption into two groups: i) those which offered (...) an explanation by using the formal cause ii) those which provided an explanation by using the material or the instrumental causes. According to Philopo­nus, when Aristotle reproaches the other philosophers for adducing no proper notion of the efficient cause he alludes to both Anaxagoras and Plato. Regarding Anaxagoras, in our view this cannot be confirmed by internal textual evidence. In terms of Plato, in this chapter we trace an explicit and an implicit criticism of the Platonic Forms as causes. Aris­totle’s implicit criticism is that the Forms are not at all active causes. We can understand better the grounds for this criticism if we also consider his relevant arguments in Book Lambda of his Metaphysics. His explicit criticism, articulated in two arguments, is formulated in GC 335b18–24. We examine the different lines of its interpretation in the second­ary literature, but primarily we focus on Philoponus’ exegesis, which contributes significantly, not only to the clarification of Aristotle’s thinking, but also to the manifestation of the arguments articulated in defence of the Platonic theory of the Forms. In this paper, through the analysis of Philoponus’ exegesis we set out to prove that Aristotle’s criticism of the Platonic causes can be construed from the perspective of either Aristo­telian theory or the Platonic and Neoplatonic influence. Finally, based on Philoponus’ exegesis, we examine Aristotle’s criticism of those who posited matter or instrumental causes as efficient causes. (shrink)

This study draws attention to the ordering of matter and form argued for in Aristotle’s Physics II, 8 (199a30–32). This argument for hylomorphic teleology relies on the presentation of nature earlier in Physics II, 1. In this way, it highlights the connections between chapter one’s account of nature as matter and form and chapter eight’s defense of final causality. Grounding final causality in the principles of nature reveals its central importance for Aristotle’s view of nature. To clarify the meaning (...) of hylomorphic teleology I contrast my interpretation of Aristotle with that of Wolfgang Wieland regarding the scope and foundation of the final cause, countering his claim that chance and universal final causality are mutually exclusive. I contend that the presentation of teleology in chapter eight supports a diverse interpretation of the final cause, one that admits chance events while not sacrificing the intrinsic ordering of matter to form.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Animals in the World: Five Essays on Aristotle’s Biology by Pierre PellegrinChristopher LutzPELLEGRIN, Pierre. Animals in the World: Five Essays on Aristotle’s Biology. Translated by Anthony Preus. Albany: State University of New York Press, 2023. vi + 324 pp. Cloth, $95.00; paper, $35.95This book explores two broad questions that have for decades been driving Pierre Pellegrin’s contributions to the so-called biological turn in Aristotle studies: whether and in (...) what sense Aristotle actually has a biology; the degree to which Aristotle’s teleological commitments lead him to characterize living things and the world that they inhabit as perfect. By analyzing various interplays that the zoological treatises posit between, on the one hand, the form and end of each species and, on the other hand, its material and efficient causes, Pellegrin reveals the astounding depth of Aristotle’s affinity with modern biology.In consideration of the millennia-spanning distance between Aristotle and the emergence of modern biology in the nineteenth century, Pellegrin first of all seeks to establish that he may call Aristotle a biologist without committing anachronism. Chapter 1 identifies two teleological notions that connect Parts of Animals and Generation of Animals to nineteenth-century conceptions of biology: Using organic function as the primary organizational principle in comparative anatomy relates Aristotle to Cuvier, and the concept of adaptation relates Aristotle to Darwin. Citing the profound influence of History of Animals on Cuvier (and thus on nineteenth-century biology), Pellegrin argues that its chief biological [End Page 357] innovation lies in the suggestion that observation is epistemically useful even when we are unable to explain that which we have observed.Chapter 2 emphasizes the role that mechanistic (that is, material and efficient) causality plays within the teleological explanations in Aristotle’s studies of animals. After a lengthy discussion of hypothetical necessity, Pellegrin uses PA 1.1’s distinction between formal nature and material nature to suggest that Aristotle recognizes an “ontological autonomy” of material nature, by which he seems to mean that matter has certain properties independent of any form. Linking Aristotle to Darwin, he argues that for Aristotle the perfection of each species consists in its fitness for (everlasting) survival. The end-directed formal nature of the species must negotiate with its autonomous material nature in order to secure for it an advantageous condition that guarantees its permanence but inevitably comes at the expense of certain disadvantages. For example, birds have no ears because they need extra matter for feathers (see PA 2.12).Shifting the focus to a crucial difference between Aristotle and modern biology, chapter 3 investigates the unity of Aristotelian natural science and biology’s place within it. Pellegrin finds analogies between Aristotle’s explanations of sexual reproduction, spontaneous generation, and Meteorology ’s account of the formation of inanimate homoiomerous matter (for example, metals, minerals). Sexual reproduction (clearly involving a material, formal, efficient, and final cause) is more causally complex than spontaneous generation (which according to Pellegrin has no preexisting final cause and only a quasi-formal cause), yet we understand spontaneous generation only by analogy with sexual reproduction, which is for Aristotle explanatorily prior. Spontaneous generation, in turn, is marginally more complex than the formation of homoiomerous matter (which also has only a quasi-formal cause and, further, no final cause at all), yet we understand the latter only by analogy with spontaneous generation and sexual reproduction. Pellegrin concludes that all natural science is united insofar as “material-efficient causality concerns all natural realities,” living and nonliving alike; however, because Aristotle in each case explains the less complex by analogy with the more complex, the teleological study of fully developed living things is explanatorily primary within his natural science. In this way, Aristotle stands in stark contrast to modern natural science, in which biology is explanatorily posterior to chemistry and physics.Chapter 4 qualifies the explanatory priority of complex organisms by challenging any notion of an Aristotelian scala naturae. Pellegrin works to show that the recognition of irreducible diversity is present in Aristotle’s very definition of an animal, arguing that in animals the nutritive faculty is neither ontologically nor developmentally prior to the sensitive and motive...

Despite the renewed interest in Aristotle’s Generation of Animals in recent years, the subject matter of GA V, its preferred mode(s) of explanation, and its place in the treatise as a whole remain misunderstood. Scholars focus on GA I-IV, which explain animal generation in terms of efficient-final causation, but dismiss GA V as a mere appendix, thinking it to concern (a) individual, accidental differences among animals, which are (b) purely materially necessitated, and (c) are only tangentially related to the topics (...) discussed in the earlier books. In this paper, we defend an alternative and more integrated account of GA V by closely examining Aristotle’s methodological introduction in GA V.1 778a16-b19 and his teleological explanation of the differences of teeth in GA V.8. We argue for the unity of both GA V and of GA as a whole and present a more nuanced theory of teleological explanation in Aristotle’s biology. (shrink)

In Posterior Analytics 1.13, Aristotle introduced a distinction between two kinds of demonstrations: of the fact (quia), and of the reasoned fact (propter quid). Both demonstrations take a syllogistic form, in which the middle term links either two facts (in the case of quia demonstrations) or a proximate cause and a fact (in the case of propter quid demonstrations). While Aristotle stated that all the terms of one demonstration must be taken from within the same subject matter, he admitted some (...) exceptions in which the fact and the reasoned fact are instantiated by terms from different sciences, as when mathematics provides the reason and another science the empirical fact. This was the methodological foundation of the “mixed sciences”, a subject of varying interpretations in the thirteenth century. Roger Bacon (C. 1220–1292), adhering to Robert Grosseteste’s (C. 1168–1563) commentary on Posterior Analytics, presented a unique interpretation of this exception. He replaced propositional demonstrations with geometrical considerations and diagrams, thus producing geometrical arguments for theorems in natural philosophy. I focus on Bacon’s propter quid arguments, as applied in three case studies: (1) the heat caused by a body moving to its natural place; (2) the motion of the scale; (3) and the contraction of water. Based on an analysis of these demonstrations, I argue that Bacon’s interpretation of propter quid demonstration reflects his application of a scientific methodology that imbues geometrical objects with causal power over material bodies.

According to most interpreters, Aristotle explains death as the result of material processes of the body going against the nature of the living being. Yet, this description is incomplete, for it does not clarify the relationship between the process of decay and the teleological system in which it occurs: this makes it impossible to distinguish between natural and violent death. In this paper, I try to fill this gap by looking at his so-called ‘biological works’ and mainly at the (...) De Juventute. I first introduce the specific concept of life at play in this treatise and prove its complementarity with the framework of the De Anima. Then, I illustrate in detail the process of dying and the reasons why a merely material description is insufficient to account for the distinction between natural and violent death. Finally, I show that for Aristotle natural death is a by-product of teleologically directed life activities: only against the background of this teleological structure is natural death fully explained in terms of essence and causes. To support this claim, I compare death to two analogous cases in Aristotle’s biology, namely dreams and the features of GA V. (shrink)

This paper shows how key aspects of Aristotle’s core concepts of matter and motion, some of which have recently been shown to help make sense of quantum mechanical indeterminacy, align with some important results of the energy-momentum relationship of special relativity. In this conception, mobility and indeterminacy are inherently linked to each other and to materiality. Applying these ideas to massless particles, which relativity tells us move at the maximal cosmic speed, allows us to draw the conclusion that they must (...) be the most basic physical bodies, that is, mobile substances. The most familiar massless particle, the photon, constitutes light. Furthermore, because the photon composes luminous matter but cannot be decomposed into anything else more basic, it fulfills the definition of element. (shrink)

IN GENERATION AND CORRUPTION 2.9, Aristotle sets out to give an account of “how many and what are the principles of all coming to be are like.” In doing so, he situates the cause “for the sake of which,” τὸ οὗ ἕρεκα, within a causal nexus familiar to readers of Physics 2. It is constituted by the end—that is, the form produced—by the matter in which it is produced, and by the agent that produces it. In Meteorology 4.12, moreover, he (...) explains that form itself must be understood in terms of the species-typical activities that follow upon its presence and for the sake of which the composite substance exists. He thus recognizes two sorts of ends, form and activity, of which the latter seems to be ultimate. Although form is the immediate end of coming to be, a composite substance exists in the last analysis for the sake of its activity. (shrink)

Descartes holds that, insofar as nature is a purposeless, unthinking, extended substance, there could be no final causes in physics. Descartes’ derivation of his three laws of motion from the perfections of God thus underwrites a rejection of Aristotle’s conception of natural self-motion and teleology. Aristotle derived his conception of the purposeful action of sublunar creatures from his notion that superlunar bodies are perfect, eternal, living beings, via the thesis that circular motion is more complete or perfect than rectilinear (...) motion. Descartes’ reduction of circular motion to rectilinear motion, achieved through his theological foundation of the laws of motion, thus marks a crucial break from Aristotle’s philosophy of nature. This paper argues that the shift from the Aristotelian conception of nature as self-moving and teleological to the Cartesian conception of nature as purposeless and inert, is not an empirical discovery but is rooted in differing conceptions of where perfection lies in nature.

In the context of Aristotle's metaphysics and natural philosophy, 'prime matter' refers to that material cause which is both the proximate material cause of the four sublunary elements and the ultimate material cause of all perishable substances. On the traditional view, prime matter is pure potentiality, without any determinate nature of its own. Against this view, I argue that prime matter must be physical, extended, and movable matter if it is to fulfil its role as the substratum (...) persisting through the generation and corruption of these elements and the individuating subject in which their defining properties are found.

Peirce was greatly influenced by Aristotle, particularly on the topic of final cause. Commentators are therefore right to draw on Aristotle in the interpretation of Peirce's teleology. But these commentators sometimes fail to distinguish clearly between formal cause and final cause in Aristotle's philosophy. Unless form and end are clearly distinguished, no sense can be made of Peirce's important claim that 'desires create classes.' Understood in the context of his teleology, this claim may be considered Peirce's answer to (...) nominalists and sceptics on the possibility and status of scientific knowledge. On the basis of an improved view of Peirce's teleology, the objection that inorganic physical events do not admit of teleological explanation can be answered. I argue that the non-teleological alternative leaves the laws of nature and the actions of inorganic matter unexplained. (shrink)

Aristotle's study of the natural world plays a tremendously important part in his philosophical thought. He was very interested in the phenomena of motion, causation, place and time, and teleology, and his theoretical materials in this area are collected in his Physics, a treatise of eight books which has been very influential on later thinkers. This volume of new essays provides cutting-edge research on Aristotle's Physics, taking into account recent changes in the field of Aristotle in terms of its (...) understanding of key concepts and preferred methodology. The contributions reassess the key concepts of the treatise, reconstruct Aristotle's methods for the study of nature, and determine the boundaries of his natural philosophy. Due to the foundational nature of Aristotle's Physics itself, the volume will be a must-read for all scholars working on Aristotle. (shrink)

The purpose of this article is to reconstruct Aristotle’s distinction between primary substances and their homonyms. It is shown that the Stagirite regards both body parts and artefacts as mere homonyms of primary substances when they are no longer capable of performing their function (ergon) and actualizing their end (telos). In the course of the present discussion, Aristotle’s approach is confronted with his famous doctrine of the four causes, whilst an analysis of the examples given by the Stagirite serves the (...) purpose of determining the ontic status of homonyms. Subsequently, this paper argues that Aristotle’s hylomorphism not only defies the functionalist assumption of the irrelevance of matter but also precludes the possibility of equating artefacts with living organisms. The discussion concludes with an observation that primary substances which are truly (alēthōs) and things which are only homonymously (plēn homōnymōs) require different definitions. (shrink)

This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, and the teleology of emerging things. He shows that Aristotle’s distinctive ontological claim—that being is inescapably diverse in kind—is anchored in his argument for the existence of change. -/- Aristotle may be the only thinker to have given a noncircular definition of change. (...) When he gave this definition, arguing that change is real was a losing proposition. To show that it exists, he had to rework the way philosophers understood reality. His groundbreaking analysis of change has long been interpreted through a Platonist lens, however, in which being is conceived as unchanging. Offering a comprehensive reexamination of the relationship between change and being in Aristotle, Sentesy makes an important contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Passion and Action: The Emotions in Seventeenth-Century Philosophy by Susan JamesRichard A. WatsonSusan James. Passion and Action: The Emotions in Seventeenth-Century Philosophy. New York: Oxford University Press, 1997. Pp. vii + 318. Cloth, $35.00.Susan James shows how during the seventeenth century philosophers moved from the three souls of Aristotle and the tripartite soul of Thomas Aquinas in which passions and reasons compete for the attention of the will, (...) to a Cartesian view of man as a single soul in union with the body who wills under the influence of both passions and reasons, to a Hobbesian view that the soul is the body and that the bodily motions we call reasons and passions are desires; acts of will are merely the deciding desires in deterministic causal sequences of the material motions of the body that constitute desires. This sets up the contemporary view that, motions are caused by desires and beliefs, leaving behind the difficulties of integrating with one another Aristotelian souls, Thomistic faculties, and Cartesian mind and body. James conceives of this evolution as one of unification of mental and bodily powers, and of integration of the active and passive powers of the mind. This concourse also represents a development from theories meant to explain to theories calculated for control and finally to theories facilitating therapy. Aristotle and Thomas adapted their ontologies to perceived differences in powers and faculties, while Descartes and Hobbes worked toward an ideal of unity of science and nature. The Christian Descartes brought together all the substances and powers of nature under a single extended matter divided into parts by the single force of motion, but he excepted the human soul with its power of will to alter the course of nature. The atheist Hobbes simply dispensed with supernatural [End Page 168] mental substance and occult power of will in order to integrate the whole of nature (including sensing and reasoning) under a cause and effect sequence of moving material bodies in which the last desire in a sequence of human bodily motions is designated as an act of will.James intends her book “as a contribution to the reinstatement of the emotions within philosophy, to the… opinion that we need to take account of our emotional life if we are to understand… moral motivation and growth, the springs of action (rational and otherwise), and the nature of reasoning” (22). She agrees that the sharp division between ideas and passions or emotions is properly abolished to be replaced by the view that all ideas have an emotional component, and all passions an ideational component. This fits with the parallel development of the notion that all sensible perceptions are propositional, and the somewhat less widespread notion that all concepts have a sensible component.But did this development result in a view of passions and ideas, learning and knowing, thinking and action, that is more true to nature than Aristotelian ontology? It is very hard to answer this question, and despite her sympathies with the notion that all human thought is both conceptual and emotional, James does not try. The reason we don’t know lies under the surface of the movement from Aristotle to Hobbes (i.e., to Daniel Dennett) like a monster in the deep. The monster is the monotheistic God, the perfection and unity of which underlies the Western drive to a unitary view of nature including man. The possibility that this God could be a deceiver, and so all our sensations and ideas might not represent the real world, set up Cartesianism and modern hypothetico-deductive science. But lurking throughout James’ book is a more palpable dreadnought, a demoness, the woman Eve. The female is responsible for the Fall of Man, and thus the fear and suspicion of women that suffuses patriarchic Christianity, and is expressed openly by such philosophers as Malebranche. Bodily passions and emotions (particularly the concupiscent ones) are nasty, evil, irrational, overpowering; to wit, they are feminine. They are not to be trusted, and must be subdued. So while still driven by ideals of monotheism, Descartes and Hobbes do move beyond the dogmatic Christian association of the emotions with female treachery. Even so... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Richard Eldridge SELF-UNDERSTANDING AND COMMUNITY IN WORDSWORTH'S POETRY Prior to die rise of modern science in die seventeenth century, to understand oneself was to know one's place in a ideologically organized universe. Human actions, together with natural events in general, were intelligible as aiming at the realization of given purposes or ends. To be a human person was to have a particular sort ofend: intellectual contemplation, according to Aristotle, (...) or oneness with God, according to Augustine. Self-knowledge becomes problematic, however, once events in nature are conceived in terms of the new physics to be only materially caused, not purposive. Given that human actions are events in nature, physical explanations then seem to be both necessary and sufficient for understanding them. It then becomes no longer possible to understand and explain one's actions as grounded in a partial grasp of an intelligible order of things. The self, it seems, is not real; bits of matter are, and their motions are mechanical, not plotted in a divinely ordered book ofnature. Thus the self or the person as a locus ofautonomous agency and understanding tends to come to be regarded as a fiction, not a physical something and not effective in the occurrence of events, so not a something at all. Human actions tend no longer to be seen as stemming from persons who can alter and are responsible for diem, but instead as complex events falling under physical laws. Yet despite the revolutionary revisions in the explanation of human action and die account of personhood seemingly forced by the new physics, self-knowledge is not something easily abandoned in favor ofknowledge of matter. It is not easy to conceive of one's actions as nonpurposive and of oneself as an unreal playdiing of fortune. Determinism seems incompatible with individual responsibility and hence with morality. Determinists make claims, investigate things, and regard diese activities as significant 273 274Philosophy and Literature and under their control, yet it is hard to see how this could be ifphysicalist determinism were true. Even within modern scientific understanding, autonomous creativity and human understanding are generally allotted roles in experimentation as well as in the rest of life. Yet this acknowledgment of human autonomy is seemingly in fundamental conflict with the commitment to the explanation of all events under physical laws that is characteristic of the modern scientific attitude.1 In the absence, however, of a well worked out description of how we can autonomously generate partial understandings of our proper ends as persons, understandings to which we then give expression in action, these objections will seem hollow, and the sense diat it must be possible to explain our actions fully under physical laws will press upon us. Ifwe cannot say how we can understand ourselves and our end in ways that inform our actions, then it will seem wise to abandon trying to understand agentive persons and to try instead to formulate the physical explanations of the motions of our bodies that are seemingly in order. Here Wordsworth's poetry can be of special value, for one of Wordsworth 's chief poetic concerns was to diagnose and locate skepticism about the possibility of self-understanding as a natural but temporary stage in the lives of persons who can grasp their proper end. Skepticism about action-guiding self-understanding, on his showing, is a plight of mind to which self-conscious end-directed beings succumb just as they most fully assert their particularity and separateness from others. Recovery from this plight occurs naturally when they come both to see that genuine autonomy requires community with others in a particular sort of expressive activity and to find themselves already so engaged. Further self-conscious and effective engagement in this expressive activity then emerges as the proper end of persons and as an end that is to be achieved communally. The scandal of philosophy, as Wordsworth would have it, is diat this natural development of die mind, a development Wordsworth traces throughout his own career, should be ignored in favor ofdie pursuit ofoverly abstract, narrow, and impoverishing causal explanations of our behavior. Wordsworth thus offers us a detailed and comprehensive description of how action-guiding self... (shrink)

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)

The vast majority of canonical early modern authors reject Aristotelian physics and metaphysics. Instead, many of them are mechanists, that is, they explain all natural change in the material world simply through the motions and collisions of inertial matter in motion. This typically means that they deny that there is immanent teleology in the natural world; sometimes, it even means eliminating purposiveness from natural philosophy altogether. Thus, some writers attempt to provide explanations of natural phenomena that do not (...) rely on teleology. Because this proves enormously difficult, others retain, or reintroduce, teleology in various forms. -/- The section “Rejections of Teleology” explores the reasons why certain early modern authors reject teleology more or less generally. The section “Defenses of Extrinsic Teleology” shows that quite a few writers embrace extrinsic teleology: they hold that many natural things and processes have ends in virtue of being part of God’s plan for the world. Some of these authors also advocate the use of teleology in natural philosophy, for instance, to discover natural laws. Finally, the section “Defenses of Immanent Teleology” shows that there are a few early modern philosophers and scientists who go even further than that, insisting on the need for immanent teleology in the natural world.

The paper examines Posterior Analytics II 11, 94a20-36 and makes three points. (1) The confusing formula ‘given what things, is it necessary for this to be’ [τίνων ὄντων ἀνάγκη τοῦτ᾿ εἶναι] at a21-22 introduces material cause, not syllogistic necessity. (2) When biological material necessitation is the only causal factor, Aristotle is reluctant to formalize it in syllogistic terms, and this helps to explain why, in II 11, he turns to geometry in order to illustrate a kind of (...) class='Hi'>material cause that can be expressed as the middle term of an explanatory syllogism. (3) If geometrical proof is viewed as a complex construction built on simpler constructions, it can in effect be described as a case of purely material constitution. (shrink)

In various texts, Aristotle assigns priority to form, in its role as a principle and cause, over matter and the matter-form compound. Given the central role played by this claim in Aristotle's search for primary substance in the Metaphysics, it is important to understand what motivates him in locating the primary causal responsibility for a thing's being what it is with the form, rather than the matter. According to Met. Theta.8, actuality [ energeia / entelecheia ] in general is prior (...) to potentiality [ dunamis ] in three ways, viz., in definition, time and substance. I propose an explicitly causal reading of this general priority claim, as it pertains to the matter-form relationship. The priority of form over matter in definition, time and substance, in my view, is best explained by appeal to the role of form as the formal, efficient and final cause of the matter-form compound, respectively, while the posteriority of matter to form according to all three notions of priority is most plausibly accounted for by the fact that the causal contribution of matter is limited to its role as material cause. When approached from this angle, the work of Met. Theta.8 can be seen to lend direct support to the more specific and explicitly causal priority claim we encounter in Met. Z.17, viz., that form is prior to matter in its role as the principle and primary cause of a matter-form compound's being what it is. (shrink)

According to most scholars, in the Parts of Animals Aristotle frequently provides explanations in terms of material necessity, as well as explanations in terms of that-for-the-sake-of-which, i.e., final causes. In this paper, I argue that we misunderstand both matter and the way that Aristotle explains things using necessity if we interpret Aristotle as explaining things in terms of material necessity. Aristotle does not use the term “matter” very frequently in his detailed discussions of animal parts; when he does (...) use it, he typically identifies blood as matter. I argue that this is because blood is, for Aristotle, what properly nourishes and grows the other parts of the body and he views nourishment and growth as types of coming-to-be. The second half of the paper turns to necessity as a cause in the Parts of Animals. I argue that in the Parts of Animals Aristotle is not interested in distinguishing between what Aristotle elsewhere treats as very different types of necessity. (shrink)

The model of social science established in methodological writings of the 1830s and 1840s formed an ideal that has endured to the beginning of the twenty-first century. Subsequent authors have been obliged to excuse the social sciences for their failure to achieve this ideal model of science, to reinterpret the successes of social science in terms of it, or to construct alternative conceptions of social science in contrast to it. The ideal was worked out in two closely related texts, Auguste (...) Comte’s Cours de Philosophie Positiveand John Stuart Mill’s A System of Logic. The positive achievement of these texts was to clarify the application of the notion of “law” to the subject matter of social science. Their negative achievement was to eliminate, as much as possible, the role of teleological thinking from the study of the social realm. The subject of this chapter will be the reformulation of the ideas of cause and teleology before and during the period of Mill and Comte, and its aftermath up to the early twentieth century in the thinking of several founding figures of disciplinary social science. The discussion to be examined here focused on the problem of the sufficiency of causal explanations, and particularly on the question of whether some particular fact could be explained without appeal to purpose. In response to such questions, the defenders of the new conception attempted to replace older terms with new ones, replacing “purpose” with “function,” for example. (shrink)

I argue that Aristotle’s account of scientific demonstrations in the Posterior Analytics is centred upon formal causation, understood as a demonstration in terms of essence (and as innocent of the distinction between form and matter). While Aristotle says that all four causes can be signified by the middle term in a demonstrative syllogism, and he discusses at some length efficient causation, much of Aristotle’s discussion is foremost concerned with the formal cause. Further, I show that Aristotle had very detailed procedures (...) for identifying the formal cause, and that he is aware of several problems which might lead one to erroneously identify the wrong form as the cause of a property. Finally, I show that Aristotle’s account can easily be adapted to material causation, and through some modifications (introduction of process universals related through parthood), hinted at in II 11-12 and 16-17, to efficient and final causation. (shrink)

My aim is to examine Aristotle's hylomorphism as a model for scientific explanation of living beings. I argue that the issue of matter-form relation should be connected with the opposition between the necessity of material and efficient causes and the teleology of forms. Form (as "telos") is a principle able to organize the appropriate conjunction of material and efficient causes. Formal and final causes are not a trick for filling the "gap in causation", nor are they bare (...) heuristic tools for inquiring into the "true" causes. The primacy of formal and final causes guarantees an appropriate account of material and efficient causes inasmuch as form and "telos" are responsible for bending and organizing the original dispositions of the material elements.
