Aristotle was the first thinker to articulate a taxonomy of scientific knowledge, which he set out in Posterior Analytics. Furthermore, the “special sciences”, i.e., biology, zoology and the natural sciences in general, originated with Aristotle. A classical question is whether the mathematical axiomatic method proposed by Aristotle in the Analytics is independent of the special sciences. If so, Aristotle would have been unable to match the natural sciences with the scientific patterns he established in the Analytics. In this paper, (...) I reject this pessimistic approach towards the scientific value of natural sciences. I believe that there are traces of biology in the Analytics as well as traces of the Analytics’ theory in zoological treatises. Moreover, for a lack of chronological clarity, I think it’s better to unify Aristotle’s model of scientific research, which includes Analytics and the natural sciences together. (shrink)

Critical notice of R. Mayhew's, The Female In Aristotle's Biology.

The aim of this paper is to evaluate the level of gender bias in Aristotle’s Generation of Animals while exercising due care in the analysis of its arguments. I argue that while the GA theory is clearly sexist, the traditional interpretation fails to diagnose the problem correctly. The traditional interpretation focuses on three main sources of evidence: (1) Aristotle’s claim that the female is, as it were, a “disabled” (πεπηρωμένον) male; (2) the claim at GA IV.3, 767b6-8 that females are (...) a departure from the kind; and (3) Aristotle’s supposed claim at GA IV.3, 768a21-8 that the most ideal outcome of reproduction is a male offspring that perfectly resembles its father. I argue that each of these passages has either been misunderstood or misrepresented by commentators. In none of these places is Aristotle suggesting that females are imperfect members of the species or that they result from the failure to achieve some teleological goal. I defend the view that the GA does not see reproduction as occurring for the sake of producing males; rather, what sex an embryo happens to become is determined entirely by non-teleological forces operating through material necessity. This interpretation is consistent with Aristotle’s view in GA II.5 that females have the same soul as the male (741a7) as well as the argument in Metaphysics X.9 that sexual difference is not part of the species form but is an affection (πάθος) arising from the matter (1058b21-4). While the traditional interpretation has tended to exaggerate the level of sexism in Aristotle’s
developmental biology, the GA is by no means free of gender bias as some recent scholarship has claimed. In the final section of the paper I point to one passage where Aristotle clearly falls back on sexist assumptions in order to answer the difficult question, “Why are animals divided into sexes?”. I argue that this passage in particular poses a serious challenge
to anyone attempting to absolve Aristotle’s developmental biology of the charge of sexism. (shrink)

Natural philosophers make mistakes. Descartes got the laws of inertia wrong, Kant misunderstood the primacy of Euclidian geometry, and almost everyone (except perhaps Aristarchus of Samos) prior to the discovery of the telescope mistakenly thought that the solar system was geocentric. That we find Aristotle mistaken on questions in the life sciences — questions which required advances such as the microscope to even articulate — should come as little surprise. There seems nothing remarkable in the fact that Aristotle mistakenly thought (...) that the constitutive elements of the world were four (earth, wind, air, fire) or that the “organ” of thought was not the brain, but the heart. But the matter is otherwise when scholars examine Aristotle’s remarks about the female in his biological writings. When Aristotle claims that the leader of a hive is the king bee (HA 8 [9].40.623b9-10), that woman have smaller brains than men (PA 2.7.653a28-9), and that the female of the species have fewer teeth than the male (HA 2.3.501b19-21), Aristotle’s critics have suspected something more nefarious than simply poor observation at work. When Aristotle goes on to claim that “the female is, as it were, a mutilated male” (GA 2.3.737a27-8) or that “the female is more dispirited and more despondent than the male, more shameless and more lying, readier to deceive and possessing a better memory for grudges” (HA 8 [9].1.608b10-12), critics have accused Aristotle of trying to pass off misogyny as science.

Aristotle is a political scientist and a student of biology. Political science, in his view, is concerned with the human good and thus it includes the study of ethics. He approaches many subjects from the perspective of both political science and biology: the virtues, the function of humans, and the political nature of humans. In light of the overlap between the two disciplines, I look at whether or not Aristotle’s views in biology influence or explain some of (...) his theses in political science. I show that we should not seek a unified answer to this question, for the relationship between the two disciplines varies depending on the topic. In some cases, e.g. the nature of the human function, the biological background is likely to be endorsed as one of the presuppositions of the ethical enquiry. In other cases, e.g. the study of social hierarchies, even though the ethical works and the biological works come to similar conclusions, it is hard to establish that the biological approach is intended to provide support to the ethico-political approach. In conclusion, I show that Aristotle’s political science and his biology are in conflict at least in two important cases: his account of justice towards non-human animals and his exhortation to contemplate.

Biology and theology are interdependent theoretical sciences for Aristotle. In prominent discussions of the divine things (the stars and their unmoved movers) Aristotle appeals to the science of living things, and in prominent discussions of the nature of plants and animals Aristotle appeals to the nature of the divine. There is in fact a single continuous series of living things that includes gods, humans, animals, and plants, all of them in a way divine. Aristotle has this continuum of divine (...) beings, and a theory of value that corresponds to it, in mind not only in key parts of his theology and biology, but also in his practical philosophy. Here I call attention to some important texts and attempt to offer a coherent account of them, without being able to enter into the usual interpretive disputes. I begin by clarifying the terms “theology” and “biology” and their place in Aristotle's division of philosophy. Next, I discuss how Aristotle’s theology is informed by his biology, and then how his biology is informed by his theology. I end by discussing some implications of the interdependence of biology and theology for Aristotle’s ethics and exhortation to philosophy. (shrink)

How does Aristotle view the production of females? The prevailing view is that Aristotle thinks female births are teleological failures of a process aiming to produce males. However, as I argue, that is not a view Aristotle ever expresses, and it blatantly contradicts what he does explicitly say about female births: Aristotle believes that females are and come to be for the sake of something, namely, reproduction. I argue that an alternative to that prevailing view, according to which the embryo’s (...) sex is determined solely by “non-teleological necessity,” also misrepresents Aristotle’s view. As I show, the explanation Aristotle gives is more sophisticated and less egalitarian than the alternative account allows: There is some sense in which males are, for Aristotle, the “default” result. I offer instead an interpretation that can accommodate the asymmetry between Aristotle’s biological account of the production of males and females, but which does not imply that females are thereby teleological failures. There is no doubt that Aristotle thinks females are inferior to males in many respects. However, if he thinks that inferiority is grounded in biological facts, it is not the fact that females are the results of a failure of form to be realized. (shrink)

In this paper I explore Aristotle’s views on natural kinds and the compatibility of pluralism and realism, a topic that has generated considerable interest among contemporary philosophers. I argue that, when it came to zoology, Aristotle denied that there is only one way of organizing the diversity of the living world into natural kinds that will yield a single, unified system of classification. Instead, living things can be grouped and regrouped into various cross-cutting kinds on the basis of objective similarities (...) and differences in ways that subserve the explanatory context. Since the explanatory aims of zoology are diverse and variegated, the kinds it recognizes must be equally diverse and variegated. At the same time, there are certain constraints on which kinds can be selected. And those constraints derive more from the causal structure of the world than from the proclivities of the classifier (hence the realism). This distinguishes Aristotle’s version of pluralistic realism from those contemporary versions (like Dupré’s “promiscuous realism”) that treat all or most classifications of a given domain as equally legitimate and not just a sub-set of kinds recognized by the science that studies it. By contrast, Aristotle privileges scientifically important kinds on the basis of their role in causal investigations. On this picture natural kinds are those kinds with the sort of causal structure that allows them to enter into scientific explanations. In the final section I argue that Aristotle’s zoology should remain of interest to philosophers and biologists alike insofar as it combines a pluralistic form of realism with a rank-free approach to classification.

This paper examines Aristotle’s two famous claims that man is by nature a political animal, and that he is the only animal who possesses speech and reason (logos). Aristotle’s thesis that man is by nature a political animal is inextricably linked with his thesis that the polis exists by nature. This paper examines the argument that Aristotle develops in Pol. I. 2 to support these two theses. It argues a) that the definition of man as an animal who possesses logos (...) is part of this argument, b) that in the chapter Aristotle understands the term “political animal” not in a broad biological sense but in a narrow sense, c) that Aristotle’s thesis that the polis is “by nature prior to the household and to the individual” is not an independent third theorem – as David Keyt and Fred D. Miller claim – but is part of this argument. (shrink)

The main aim of my paper is to analyse Aristotle’s theory of language in the context of his Physics I.1 and via an analysis and an interpretation of this part of his Physics I try to show that (i) the study of human language (logos) significantly falls within the competence of Aristotle’s physics (i.e. natural philosophy), (ii) we can find the results of such (physical) inquiry in Aristotle’s zoological writings, stated in the forms of the first principles, causes and elements (...) of the human speech (logos) and (iii) the analogies (Phys. 184b13-14) made by Aristotle at the very end of the first chapter make better sense if we consider them in the broader context in which Aristotle recognizes language as a complex natural phenomenon we are born into and which has to be not only biologically, but also socially developed through our lives. Hence, I aim towards a more naturalistic reading of Aristotle’s views on language. (shrink)

This paper explores the anatomical foundations of Aristotle's natural philosophy. Rather than simply looking at the body, he contrives specific procedures for revealing unmanifest phenomena. In some cases, these interventions seem extensive enough to qualify as experiments. At the work bench, one can observe the parts of animals in the manner Aristotle describes, even if his descriptions seem at odds with 20th century textbooks. Manipulating animals allows us to recover his teleological thought more fully. This consideration of Aristotle as (...) a sophisticated biologist helps our reading of his writings in other areas of philosophy. (shrink)

This article argues for an interpretation of Aristotle’s biological account of familial resemblance that allows us to read Aristotle’s embryology as employing the same concept of “form” as he employs in his Metaphysics. The dominant view for the last several decades has been that in order to account for the phenomenon of inherited characteristics, Aristotle’s biology must appeal to a “sub-specific” form, one that includes all of the traits that parents pass on to their offspring. That view, however, is (...) not only inconsistent with Aristotle’s essentialist metaphysics, but it also renders the embryological theory internally inconsistent. The interpretation I offer avoids both inconsistencies, and better coheres with what he actually says in Generation of Animals. (shrink)

Starting with Aristotle and moving on to Darwin, Marco Solinas outlines the basic steps from the birth, establishment and later rebirth of the traditional view of living beings, and its overturning by evolutionary revolution. The classic framework devised by Aristotle was still dominant in the 17th Century world of Galileo, Harvey and Ray, and remained hegemonic until the time of Lamarck and Cuvier in the 19th Century. Darwin's breakthrough thus takes on the dimensions of an abandonment of the traditional finalistic (...) theory. It was a transition exemplified in the morphological analysis of useless parts, such as the sightless eyes of moles, already discussed by Aristotle, which Darwin used as a crowbar to unhinge the systematic recourse to final causes. With many excerpts, a chronological sequence and an analytical approach, this book follows the course of the two conceptions that have shaped the destiny of life sciences in western culture.

[penultimate draft; prepared for publication in Aristotle’s Parts of Animals: A Critical Guide, ed. Sophia Connell – please cite final version] -/- Parts of Animals II.10 makes a new beginning in Aristotle’s study of animals. In it, Aristotle proposes to “now speak as if we are once more at an origin, beginning first with those things that are primary” (655b28-9). This is the start of his account of the non-uniform parts of blooded animals: parts such as eyes, noses, mouths, etc., (...) as opposed to uniform parts like blood and flesh. PA II.10 proposes a new strategy for studying these parts: “one ought to speak about the human kind first” (656a10). Beginning “first” with the “primary” things thus amounts to beginning with humans (655b28-9). -/- Why does Aristotle think this strategy is appropriate for his project? One answer is that it reflects a fundamental anthropocentrism. Lloyd, for instance, has raised the possibility that the basic assumptions that guide Aristotle’s biology may to some extent reflect the anthropocentrism of his culture, where the relation of humans to animals was “a preoccupation of popular beliefs”. In this paper, I develop an interpretation that both builds on and challenges this suggestion. I do so by investigating how Aristotle thinks this strategy works in theory and in practice: his justifications for adopting it and its interaction with his scientific commitments. I argue that Aristotle adopts it in part because he thinks that humans are such that his scientific concepts apply to them in a particularly clear way. (This too is a form of anthropocentrism: one that might be resisted by arguing that humans are not the best illustrations of these concepts—that Aristotle ought to look elsewhere for models with the features he desires.) -/- More specifically, Aristotle holds that starting with humans helps establish the causal explanations of the parts of other animals, particularly when they are recalcitrant. What makes humans suitable for this role is a special teleological relation between their parts and the ends they serve: in humans, he supposes, this connection is particularly tight (in a way I explain below). Consequently, Aristotle thinks he can use humans to illuminate which sorts of features tend to be for the sake of which ends, and then extend the results of this inquiry to the parts of the other animals.

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)

Essentialism in philosophy is the position that things, especially kinds of things, have essences, or sets of properties, that all members of the kind must have, and the combination of which only members of the kind do, in fact, have. It is usually thought to derive from classical Greek philosophy and in particular from Aristotle’s notion of “what it is to be” something. In biology, it has been claimed that pre-evolutionary views of living kinds, or as they are sometimes (...) called, “natu-ral kinds”, are essentialist. This static view of living things presumes that no tran-sition is possible in time or form between kinds, and that variation is regarded as accidental or inessential noise rather than important information about taxa. In contrast it is held that Darwinian, and post-Darwinian, biology relies upon varia-tion as important and inevitable properties of taxa, and that taxa are not, therefore, kinds but historical individuals. Recent attempts have been made to undercut this account, and to reinstitute essentialism in biological kind terms. Others argue that essentialism has not ever been a historical reality in biology and its predecessors. In this chapter, I shall outline the many meanings of the notion of essentialism in psychology and social science as well as science, and discuss pro- and anti-essentialist views, and some recent historical revisionism. It turns out that nobody was essentialist to speak of in the sense that is antievolutionary in biology, and that much confusion rests on treating the one word, “essence” as meaning a single notion when in fact there are many. I shall also discuss the philosophical implica-tions of essentialism, and what that means one way or the other for evolutionary biology. Teaching about evolution relies upon narratives of change in the ways the living world is conceived by biologists. This is a core narrative issue. (shrink)

This collection of essays is the product of a conference on Aristotle’s Posterior Analytics (Apo) held at the University of North Carolina at Chapel Hill in 2009. The essays address three main questions: (1) “How does the APo model of scientific knowledge, focused as it is on the construction of syllogisms, relate to the scientific accounts Aristotle presents elsewhere, especially in the biological treatises?’ (2) ‘How do the arguments and views presented in the APo relate to other aspects of Aristotle’s (...) philosophy?’ and (3) ‘How do the remarks in the concluding chapter of the APo concerning perception, memory, experience, and the grasp of the universal add up to an explanation of how we come to know first principles?’ The papers by J.G. Lennox, M. Leunissen and R. McKirahan address the first two questions, while those by M. Tuominen and G. Salmieri discuss the well-known passage in Apo II 19. (shrink)

Much has been made of how Darwinian thinking destroyed proofs for the existence of God from ‘design’ in the universe. I challenge that prevailing view by looking closely at classical ‘teleological’ arguments for the existence of God. One version championed by Aristotle and Thomas Aquinas stems from how chance is not a sufficient kind of ultimate explanation of the universe. In the course of constructing this argument, I argue that the classical understanding of teleology is no less necessary in modern (...) Darwinian biology than it was in Aristotle's time. In fact, modern biology strengthens the claims that teleological arguments make by vindicating many of their key features. As a consequence, I show how Aristotle and Aquinas' teleological argument for an intelligent First Cause remains valid. (shrink)

In this paper I address an important question in Aristotle’s biology, What are the causal mechanisms behind the transmission of biological form? Aristotle’s answer to this question, I argue, is found in Generation of Animals Book 4 in connection with his investigation into the phenomenon of inheritance. There we are told that an organism’s reproductive material contains a set of "movements" which are derived from the various "potentials" of its nature (the internal principle of change that initiates and controls (...) development). These movements, I suggest, function as specialized vehicles for communicating the parts of the parent’s heritable form during the act of reproduction. After exploring the details of this mechanism, I then take up Aristotle’s theory of inheritance proper. At the heart of the theory are three general principles (or 'laws') that govern the interactions between the maternal and paternal movements, the outcome of which determines the pattern of inheritance for the offspring. Although this paper is primarily aimed at providing a detailed analysis of Aristotle’s account of inheritance, the results of that analysis have implications for other areas of Aristotle’s biology. One of the most interesting of these is the question of whether Aristotle’s biology is anti-evolutionary (as traditionally assumed) or whether (as I argue) it leaves room for a theory of evolution by natural selection, even if Aristotle himself never took that step.

Explains Aristotle's views on the possibility of continuous variation between biological species. While the Porphyrean/Linnean classification of species by a tree suggests species are distributed discretely, Aristotle admitted continuous variation between species among lower life forms.

The Aristotelian axiom that function follows form was beautifully instantiated in molecular biology by the discovery of DNA’s structure that immediately suggested how DNA might work as depository and vehicle for genetic information. However, later on molecular biology became infatuated with the gene that became the center of the universe. This gene-centered viewpoint is an obstacle for the emerging field of evo-devo aiming at finding the causal connections between evolution and biological development. Here it is argued that molecular (...) biology must reject the narrow-minded causality associated with the gene-centered view and so it must recover to the spirit of Aristotelian natural history and its four types of causation in order to foster the evo-devo field of research.

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

Aristotle (384-322 BC) was an ancient Greek philosopher, pupil of Plato, and tutor of Alexander the Great. His works span the topics of biology, metaphysics, mind, logic, language, science, epistemology, ethics, and politics. Aristotle held that there are many divine beings, but a supremely divine being is the first cause of the universe and the goodness of all other beings. This divine being plays a fundamental explanatory role in Aristotle’s thought.

It has become somewhat of a platitude to call Aristotle the first epigenesist insofar as he thought form and structure emerged gradually from an unorganized, amorphous embryo. But modern biology now recognizes two senses of “epigenesis”. The first is this more familiar idea about the gradual emergence of form and structure, which is traditionally opposed to the idea of preformationism. But modern biologists also use “epigenesis” to emphasize the context-dependency of the process itself. Used in this sense development is (...) not simply the unfolding of a pre-determined sequence of changes specified in advance by the organism’s genotype. It is also sensitive to inputs from the internal and external environment, which help determine in real-time which of the many potential developmental pathways are actualized during the process. Within this paradigm developing embryos are viewed as dynamic and responsive systems that react to inputs from the internal and external environment ‘on the fly’. In this paper I argue that, while Aristotle was an epigenesist in the first sense, he would have rejected epigenesis in the more modern sense. First, Aristotle’s model of choice for a developing embryo is the automaton that executes a set of preset movements (GA 734b9-13, 741b7-15). The automatons he has in mind are not dynamic AI systems capable of modifying their behaviour on the fly in response to environmental cues but completely deterministic mechanisms whose movements are fixed by their original design. Second, given Aristotle’s views about the different kinds of causal powers there are, it looks like only intentional agents endowed with actual decision-making powers could be capable of the sort of plasticity at the core of a more dynamic epigenesis. For that kind of epigenesis requires powers for alternative outcomes, and Aristotle is explicit that such powers require rational desires (προαίρεσις) that control which of those alternatives to bring about. If I am right, then he could not have made sense of the idea of a developing embryo (as a non-intentional system) making adjustments to its phenotype on the fly in response to emerging problems and opportunities, given the conceptual resources available to him. (shrink)

Despite his awareness that organisms are well suited to the habitats they are typically found in, Aristotle nowhere tries to explain this. It is unlikely that he thinks this “fit” (as I call it) between organisms and their habitats is simply a lucky coincidence, given how vehemently he rejects that as an explanation of the fit between organisms’ various body parts. But it is quite puzzling that Aristotle never explicitly addresses this, since it is a question that seemed so pressing (...) to later philosophers and biologists such as Darwin. In this paper I offer a solution to that puzzle. As I argue, the type of habitat an organism lives in is partly constitutive of its essence or nature. The reason Aristotle does not ask, for instance, why marsh-dweller birds live in marshes, is that it is simply constitutive of their nature that they do so. Given that habitat is built into a kind’s essence, the answer to such a question is obvious and the question would have seemed to him trivial. By attending to the details of his biological treatises, I show that Aristotle’s conception of a living being’s essence is much more nuanced than one can glean from his discussions in the Physics and Metaphysics alone. (shrink)

This chapter addresses an interpretive question about why Aristotle identifies generation, growth and nourishment as the three distinct functions or activities of nutritive soul. Scholars typically try to explain this by appealing to the shared goal of these activities, though there is no consensus about what that goal is: Does Aristotle think that generation is a way of keeping oneself alive (and thus that the shared goal is self-maintenance), or is nourishment really a quasi-generative activity (and thus that the shared (...) goal is “form (re)production”)? Rather than taking that approach, Gelber offers a different but complementary way of accounting for the unity of these activities, by focussing on the continuity of their shared physiological basis. As it is argued here, the fact that these biological processes form a continuous cycle stems from Aristotle’s adherence, in his biological theory, to principles from his hylomorphic metaphysics. Attending to the details in works such as Generation of Animals that focus on the mechanisms underlying generation, growth and nourishment, it is shown how we can construct a coherent account of the unity of the three nutritive soul activities.

How many scientific demonstrations can a single phenomenon have? This paper argues that, according to Aristotle's theory of scientific knowledge as laid out in the Posterior Analytics, a single conclusion may be demonstrated via more than one explanatory middle term. I also argue that this model of multiple demonstration is put into practice in the biological writings. This paper thereby accomplishes two related goals: it clarifies certain relatively obscure passages of the Posterior Analytics and uses them to show how (...) Aristotle explains biological phenomena by reference to both final and material causes in the Parts of Animals. The first part of the paper explains the account of multiple demonstration present in the Posterior Analytics and distinguishes it from another kind of plural explanation rejected by Aristotle. The second part of the paper turns to the biological explanation in the Parts of Animals and shows how Aristotle's account of multiple demonstrations works in practice. The paper thus provides evidence for the claim that the ‘applied’ reasoning on display in the biological works is in harmony with the framework of the logical treatises, and thus may also shed light on questions of the unity of the Aristotelian corpus.

Aristotle is the first philosopher on record to subject the meaning of life to systematic philosophical examination: he approaches the issue from logical, psychological, biological, and anthropological perspectives in some of the central passages in the Corpus Aristotelicum and, it turns out, in some fragments from his (lost) early popular work the Protrepticus (Exhortation to Philosophy). From an Aristotelian perspective, in asking about life’s “meaning”, we may be asking either a theoretical question about the definition of the term life (and (...) this either generically or with specific reference to human life), or a practical question about the final end or purpose of life (or human life). Aristotle carefully considered both questions, and in his view answering the theoretical question is the key to answering the practical question. In brief, his theoretical view is that humans are distinguished from all other living things, and thus defined by their ability to use reason; thus his practical view is that the end or purpose of human existence is intellectual activity, especially doing philosophy.

This note discusses the importance of Natural History (biology) in the development of Aristotle philosophy and scientific outlook, and so the importance of considering Aristotle's philosophy as a necessary and useful background for contemporary biology.

: In Parts of Animals II.10, 655b37-656a8, Aristotle tacitly identifies a group of animals which partake of “ living only”. This paper is an attempt to understand the nature of this group. It is argued that it is possible to make sense of this designation if we consider that some animals, which are solely endowed with the contact senses, do nothing more than mere immediate nutrition by their perceptive nature and have no other action. It is concluded that some of (...) Aristotle ’s merely living animals would be certain kinds of sponge, certain sea anemones and the ascidians among testacea. (shrink)

The anti-reductionist character of the recent philosophy of biology and the dynamic development of the science of emergent properties prove that the time is ripe to reintroduce the thought of Aristotle, the first advocate of a “top-down” approach in life-sciences, back into the science/philosophy debate. His philosophy of nature provides profound insights particularly in the context of the contemporary science of evolution, which is still struggling with the questions of form, teleology, and the role of chance in evolutionary processes. (...) However, although Aristotle is referenced in the evolutionary debate, a thorough analysis of his theory of hylomorphism and the classical principle of causality which he proposes is still needed in this exchange. Such is the main concern of the first part of the present article which shows Aristotle’s metaphysics of substance as an open system, ready to incorporate new hypothesis of modern and contemporary science. The second part begins with the historical exploration of the trajectory from Darwin to Darwinism regarded as a metaphysical position. This exploration leads to an inquiry into the central topics of the present debate in the philosophy of evolutionary biology. It shows that Aristotle’s understanding of species, teleology, and chance – in the context of his fourfold notion of causality – has a considerable explanatory power which may enhance our understanding of the nature of evolutionary processes. This fact may inspire, in turn, a retrieval of the classical theology of divine action, based on Aristotelian metaphysics, in the science/theology dialogue. The aim of the present article is to prepare a philosophical ground for such project. (shrink)

Pierre Pellegrin has devoted his scholarly life to the understanding of Aristotle the political philosopher, Aristotle the life-scientist, and—perhaps most importantly—Aristotle the analyst of life-science who is also a political philosopher. Like D. M.

Is integrative biology a good idea, or even possible? There has been much interest lately in the unifica- tion of biology and the integration of traditionally separate disciplines such as molecular and develop- mental biology on one hand, and ecology and evolutionary biology on the other. In this paper I ask if and under what circumstances such integration of efforts actually makes sense. I develop by example an analogy with Aristotle’s famous four “causes” that one can (...) investigate concerning any object or phenomenon: material (what something is made of), formal (what distinguishes that particular object from others), efficient (how was the object made) and final (why was the object made). The example is provided by ongoing research on different aspects of flowering time in the model system Arabidop- sis, a small weed belonging to the mustard family. I show that understanding how flowering time is controlled is an epistemologically different sort of question from why and how it evolved, and that the two research agendas can be pursued largely independently of each other. Toward the end, I propose that the real goal of integrative biology is to understand the boundary layers between levels of biologi- cal analysis, something to which modern philosophy of science can contribute significantly.

I discuss the volume edited by Andrea Falcon and Stasinos Stavrianeas which includes a new Greek text of Aristotle's De incessu animalium (On the Progression of Animals) by Pantelis Golitsis and nine interpretative essays. Since the De incessu is largely uncharted territory, my main goal is to introduce some of the exegetical debates initiated in this volume and to hint at points of departure for further discussion. I pay particular attention to the famous principle that nature does nothing in (...) vain. (shrink)

Teleology has a complicated history in the biological sciences. Some have argued that Darwin’s theory has allowed biology to purge itself of teleological explanations. Others have been content to retain teleology and to treat it as metaphorical, or have sought to replace it with less problematic notions like teleonomy. And still others have tried to naturalize it in a way that distances it from the vitalism of the nineteenth century, focusing on the role that function plays in teleological explanation. (...) No consensus has seemed possible in this debate. This paper takes a different approach. It argues that teleology is a perfectly acceptable scientific notion, but that the debate took an unfortunate misstep some 2300 years ago, one that has confused things ever since. The misstep comes in the beginning of Aristotle’s Physics when a distinction is made between two types of teleological explanation. One type pertains to artifacts while the other pertains to entities in nature. For Aristotle, artifacts are guided by something external to themselves, human intentions, while natural entities are guided by an internal nature. We aim to show that there is, in fact, only one type of legitimate teleological explanation, what Aristotle would have considered a variant of an artifact model, where entities are guided by external fields. We begin with an analysis of the differences between the two types of explanation. We then examine some evidence in Aristotle’s biological works suggesting that on account of his natural-artifactual distinction, he encountered difficulties in trying to provide teleological accounts of spontaneous generation. And we show that it is possible to resolve these difficulties with a more robust version of an artifact model of teleology, in other words, with an externalist teleology. This is McShea’s model, in which goal-directed entities are guided by a nested series of upper-level fields. To explain teleological behavior, this account invokes only external physical forces rather than mysterious internal natures. We then consider how field theory differs from other efforts to naturalize teleology in biology. And finally, we show how the account enables us to grapple with certain difficult cases – genes and intentions – where, even in biology today, the temptation to posit internal natures remains strong.

In Aristotle’s writings regarding the biology of embryology, especially in the Generation of Animals, he contends that the mother’s menstrual fluids provide the material for the generation of the offspring, and the father’s form determines its formation as a member of that species (e.g. human). The katamenia (menstrual fluids) of the mother are said to be potentially all the body parts of the offspring, though actually none of them. So, the fluids are potentially the offspring. But are they a (...) first potentiality or second potentiality (first actuality) of a human, in the terminology of De Anima II? In this paper I will argue that katamenia are a first potentiality of a human. My first argument is that katamenia do not have the potential for human activities such as thinking, but rather the potential of becoming something having the potential for those activities. I answer the objection that katamenia are not even a first potentiality, by appealing to an important text contending that for any x whose source of becoming is external, x is potentially y if nothing in x with respect to matter needs to be changed in order for an external principle to make x into y.

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)

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)

Recently scholars have been claiming that Aristotle’s biological explanations treat “facts about matter”—facts such as the degree of heat or amount of fluidity in an organism’s material constitution—as explanatorily basic or “primitive.” That is, these facts about matter are taken to be unexplained, brute facts about organisms, rather than ones that are explained by the organism’s form or essence, as we would have expected from Aristotle’s general commitment to the causal and explanatory priority of form over matter. In this paper, (...) I present three considerations for rejecting the view that facts about matter are primitive. First, there is evidence that those putative unexplained facts about degrees of heat, dryness, fluidity, etc. are, in fact, explained. Second, there are certain cases, such as human intelligence, where it would be quite implausible to consider the explanation in terms of degrees of heat to be starting from what Aristotle considers primitive facts. Third, the idea that facts about matter are as explanatorily primitive as facts about form requires a particular conception of the causal processes that the explanations mirror. But this conception of the causal processes conflicts with the way Aristotle characterizes them in Generation of Animals. There, heat is not treated as a causal factor that works “independently” of soul. In my view, these three considerations provide compelling reason to reject the claim that Aristotle’s biology treats facts about matter as primitive. (shrink)

Aristotle’s Poetics defends the value of tragic poetry, presumably to counter Plato’s critique in the Republic. Can this defense resonate with something larger and rather surprising, that Aristotle’s overall philosophy displays a tragic character? I define the tragic as pertaining to indigenous and inescapable limits on life, knowledge, control, achievement, and agency. I explore how such limits figure in Aristotle’s physics, metaphysics, and biological works. Accordingly I want to disturb the common account of Aristotle’s thought as a neat system of (...) ontological order and metaphysical closure—not to exclude such elements but to place them within a world-view that includes certain limits at the edges of being.

The article deals with some textual issues related with Aristotle’s treatise “On Youth and Old Age, Life and Death. This text is conventionally included in the so-called “small scientific works”. In the article I considers the title variants testified in the sources as well as the place the treatise occupies within the set of Aristotle’s scientific works. I trace the parallels of this treatise with another Aristotle’s works, such as “De longitudine et brevitate vitae” and “De anima”. The treatise is (...) further compared with Aristotle’s works on physics and biology, esp. “De partibus animalium”, “De motu animalium”, “De generatione animalium”. I discuss the concept of life, functions of the vegetative soul, its “medial” location, and Aristotle’s definition of the soul’s and body’s «midpoint» in respect to the «upward» and «downward» directions. For understanding the meaning of the term «innate natural heat» it is proposed to compare it with the terminology of such Aristotelian works as “De motu animalium” and “De generatione animalium”.

This study shows that Aristotle’s introduction of the concept of substance represents a caesura in the history of ontology. The study takes two values for substance into consideration, which are a) substance as an organism (as a biological entity) and b) substance as essence, nature, form of an organism. Substances as organisms are biological concretized properties. Substance as form is the soul directing the organism and the development of the organism; the soul is both the principle of life of the (...) organism and the program which is realized in the organism. The substance as an organism is assigned the central position in Aristotle’s ontology: the organism is not reduced to forces or factors which should have an ontological primacy over the organism; the principle of life and activity of every organism is put into the biological entity and it is not identified with factors that lie outside the organism.

I argue that Aristotle’s teleology in natural science (more specifically, in biology) is not incompatible with his admissions of the “brute necessity” of the movements of matter. Aristotle thinks that the brute necessity emerging from the movements of matter is not sufficient to explain why living beings are what they are and behave the way they behave. Nevertheless, Aristotle takes this brute necessity to be a sine qua non condition in biological explanations. The full explanation of the features of (...) living beings requires the hylomorphic model, in which the brute necessity belonging to the matter is subordinated to the teleological causality of the form. The model for which I argue is pretty much Balme’s “cybernetic”. However, I explore some aspects of Aristotle’s texts that have not received much attention in the recent literature. (shrink)
