Aristotle’s theory of spontaneous generation offers many puzzles to those who wish to understand his theory both within the context of his biology and within the context of his more general philosophy of nature. In this paper, I approach the difficult and vague elements of Aristotle’s account of spontaneous generation not as weaknesses, but as opportunities for an interesting glimpse into the thought of an early scientist struggling to reconcile evidence and theory. The paper has two goals: to give as (...) charitable and full an account as possible of what Aristotle’s theory of spontaneous generation was, and to examine some of its consequences; and to reflect on Aristotle as a scientist, and what his comments reveal about how he approached a difficult problem. In particular, I propose that the well-recognized problem of the incompatibility between Aristotle’s concept of spontaneity and his theory of spontaneous generation presents an opportunity for insight into his scientific methodology when approaching ill-understood phenomena.

As a first shot, one might say that environmental ethics is concerned distinctively with the moral relations that exist between, on the one hand, human beings and, on the other, the non-human natural environment. But this really is only a first shot. For example, one might be inclined to think that at least some components of the non-human natural environment have independent moral status, that is, are morally considerable in their own right, rather than being of moral interest only to (...) the extent that they contribute to human well-being. If so, then one might be moved to claim that ethical matters involving the environment are best cashed out in terms of the dutes and responsibilities that human beings have to such components. If, however, one is inclined to deny independent moral status to the non-human natural environment or to any of its components, then one might be moved to claim that the ethical matters in question are exhaustively delineated by those moral relations existing between individual human beings, or between groups of human beings, in which the non-human natural environment figures. One key task for the environmental ethicist is to sort out which, if either, of these perspectives is the right one to adopt—as a general position or within particular contexts. I guess I don’t need to tell you that things get pretty complicated pretty quickly. (shrink)

Michael Scot’s thirteenth-century Arabic-Latin translation of Aristotle’s zoological works strongly influenced the medieval reception of these books. Whereas Scot’s translation was mostly scientific, a growing public was offered the opportunity to experience the pleasures of this kind of knowledge in general.

There has been a long-standing opposition to genetically modified organisms worldwide. Some studies have tried to identify the deep-lying philosophical, conceptual as well as psychological motivations for this opposition. Philosophical essentialism, psychological essentialism, and vitalism have been proposed as possible candidates. I approach the plausibility of the claim that these notions are related to GMO opposition from a historical perspective. Vitalism and philosophical essentialism have been associated with anti-GMO stance on account of their purported hostility to species and organismic mutability. (...) I show that vitalism has often been associated to various mutabilist theories, whereas the case for philosophical essentialism as motivating GMO opposition depends on the now discredited Essentialism Story that had constructed essentialism as a predominant view in pre-Darwinian science. Further, as philosophical essentialism taken seriously is incompatible with the reality of genetic engineering, it is unlikely to be a reason for opposition. Psychological essentialism, involving an instinctive repulsion from the practice of manipulating what is thought to be the essence of living beings, is a more likely reason for resistance to transgenesis. Yet even here, historical considerations are crucial. Not only lay people tend to essentialize genes, but scientists themselves can be shown to have been complicit in essentialist tendencies. From the advent of modern genetics, the imagery of the all-powerful genes, often depicted by scientists themselves metaphorically as material counterparts of the now obsolete vitalistic agent, has permeated the language of leading scientific figures, whose influence in shaping public opinion should not be downplayed. Enthusiasm for genetic engineering and the abhorrence from it might both derive from the same unrealistic image of the essential gene, the revision of which thus holding out the hope for transcending the present impasse of the GMO controversy.

Humans come prepared to recognize two fundamental features of our surroundings: animate objects and agents. This recognition begins early in ontogeny and pervades our ecological and social space. This cognitive capacity reveals an important adaptation and sets the conditions for pervasive shared experiences. One feature of our species and our evolved cephalic substrates is that we are prepared to recognize self-propelled action in others. Our cultural evolution is knotted to an expanding sense of shared experiences.

The definition of biological individuality is one of the most discussed topics in philosophy of biology, but current debate has focused almost exclusively on evolution-based accounts. Moreover, several participants in this debate consider the notions of a biological individual and an organism as equivalent. In this paper, I show that the debates would be considerably enriched and clarified if philosophers took into account two elements. First, physiological fields are crucial for the understanding of biological individuality. Second, the category of biological (...) individuals should be divided into two subcategories: physiological individuals and evolutionary individuals, which suggests that the notions of organism and biological individual should not be used interchangeably. I suggest that the combination of an evolutionary and a physiological perspective will enable biologists and philosophers to supply an account of biological individuality that will be both more comprehensive and more in accordance with scientific practices.

ABSTRACT:I argue that there are, according to Aristotle, two importantly different kinds of goals or ends in the domain of human agency and that one of these two kinds has been frequently, though not universally, overlooked. Apart from psychological goals, goals that agents adopt as their purposes, there are also, I submit, goals that actions have by being the kinds of actions they are and, in some cases, by occurring in the circumstances in which they do. These latter goals belong (...) to suitable actions whether or not agents adopt them as purposes and whether or not agents are aware of them. There is evidence both in Aristotle's ethical writings and in his discussion of chance and luck in Physics II.4–6 that he recognizes goals of this latter kind. (shrink)

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)

This article examines Machiavelli’s image of humanity. It argues against the prevailing views that characterize it either as pessimistic or optimistic and defends the thesis that the Florentine has a realist image of humanity. Machiavelli is a psychological egoist who conceives of man as a being whose actions are motivated by his drives, appetites, and passions, which lead him often to immoral behavior. Man’s main drives are “ambition” (ambizione) and “avarice” (avarizia). This article also investigates Machiavelli’s concept of nature and (...) shows that, for him, the constancy of human nature is the central premise that makes the scientific analysis of politics possible. Despite the fact that human drives and capabilities are the same at all times, good laws, military training, and religion allow man to be changed and educated toward “virtue” (virtù). To make such changes in man, however, presupposes a good legal and political order. Machiavelli justifies the state because of its capacity to reshape human nature and to improve man. The state is not only a coercive power but a moral institution. This leads to the conclusion that Machiavelli does not separate politics from morality as most scholars claim. (shrink)

This paper examines the nature of ‘reasonable’ argumentation in Generation of Animals III.10. Its aim is to develop an alternative to the dialectical construal of reasonable argumentation in Aristotle recently favoured by Robert Bolton. On the basis of a close textual analysis I show that the reasonable arguments deployed in Generation of Animals III.10 do not appeal to endoxa or reputable beliefs per se. Instead, they rely upon general facts about animals established by empirical induction. This implies that, contra Bolton, (...) not all reasonable arguments in Aristotle are dialectical; some, in fact, are thoroughly empirical and scientific. I conclude by suggesting that such empirical reasonable arguments even have a place in the De Caelo, the treatise that Bolton primarily focused upon when developing his interpretation. (shrink)

Beginning the nineteenth-century and continuing down to the present, many authors writing on the history of geology and paleontology have attributed the theory that fossils were inorganic formations produced within the earth, rather than by the deposition of living organisms, to the ancient Greeks and Romans. Some have even gone so far as to claim this was the consensus view in the classical period up through the Middle Ages. In fact, such a notion was entirely foreign to ancient and medieval (...) thought and only appeared within the manifold of ‘Renaissance episteme,’ the characteristics of which have often been projected backwards by some historians onto earlier periods. This paper endeavors to correct this error, explain the development of the Renaissance view, describe certain ancient precedents thereof, and trace the history of the misinterpretation in the literature. -/- .

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.

Whitehead’s metaphysics involves an event ontology. Fundamental—that is, in Whitehead’s language: “actual”—entities are events, described as acts of experience. It also involves presentism since past events have perished and future events do not yet exist according to Whitehead. Hence the question alluded to in the title of the present paper: “How are you going to move forward into the future?… If you conceive it under the guise of a temporal transition into the non-existent, you can’t get going.” I will argue (...) that, to a large extent, Whitehead’s metaphysics is designed to answer that question.

At Metaphysics A 5 986a22-b2, Aristotle refers to a Pythagorean table, with two columns of paired opposites. I argue that 1) although Burkert and Zhmud have argued otherwise, there is sufficient textual evidence to indicate that the table, or one much like it, is indeed of Pythagorean origin; 2) research in structural anthropology indicates that the tables are a formalization of arrays of “symbolic classification” which express a pre-scientific world view with social and ethical implications, according to which the presence (...) of a principle on one column of the table will carry with it another principle within the same column; 3) a close analysis of Aristotle's arguments shows that he thought that the table expresses real causal relationships; and 4) Aristotle faults the table of opposites with positing its principles as having universal application and with not distinguishing between those principles that are causally prior and those that are posterior. Aristotle's account of scientific explanation and his own explanations that he developed in accordance with this account are in part the result of his critical encounter with this prescientific Pythagorean table.

During the Middle Ages Aristotle's treatises were accessible to intellectuals via translations and commentaries. Among his works on natural philosophy, the zoological books received relatively little scholarly attention, though several medieval commentators carefully studied Aristotle's investigations of the animal kingdom. Averroes completed in 1169 a commentary on an Arabic translation of Aristotle's Parts of Animals and Generation of Animals. In 1323 Gersonides completed his supercommentary on a Hebrew translation of Averroes' commentary. This article examines how these two medieval commentators interpret (...) the first book of Aristotle's Parts of Animals, at the center of which stand methodological questions regarding the study of animals. Aristotle's discussion of classification is presented by Averroes and Gersonides in light of an epistemological debate concerning the requisite method for scientific inquiries and discoveries. Sense perception is contrasted with rational reasoning, and ultimately a combined method is proposed, sense perception maintaining supremacy. These commentators outline a clear link between the systematic arrangement of animal species as offered by Aristotle, and his subsequent logical demonstrations which, according to them, form the core of biological investigations.

This article revises Foucault's account of biopolitics in the light of the impact of the molecular and digital revolutions on `the politics of life itself'. The confluence of the molecular and digital revolutions informationalizes life, providing an account of what it is to be a living thing in terms of complex adaptive and continuously emergent, informationally constituted, systems. Also revisiting Foucault's The Order of Things and its interrogation of the modern analytics of finitude, the article argues that our contemporary politics (...) of life is therefore distinguished by the quasi-transcendentals that now distinguish informationalized life: circulation, connectivity and complexity. Here, too, the article argues, the figure of Man, which once united the quasi-transcendentals of life, labour and language, is replaced by the contingency that now unites circulation, connectivity and complexity. Observing that a life of continuous emergence is also one in which production is continuously allied with destruction, such a life is lived as the continuous emergency of its own emergence. This account of contemporary biopolitics, together with its emergency of emergence, contrasts, in particular, with that offered by Agamben in his appropriation of Schmitt. (shrink)

Historically embryogenesis has been among the most philosophically intriguing phenomena. In this paper I focus on one aspect of biological development that was particularly perplexing to the ancients: self-organisation. For many ancients, the fact that an organism determines the important features of its own development required a special model for understanding how this was possible. This was especially true for Aristotle, Alexander, and Simplicius, who all looked to contemporary technology to supply that model. However, they did not all agree on (...) what kind of device should be used. In this paper I explore the way these ancients made use of technology as a model for the developing embryo. I argue that their different choices of device reveal fundamental differences in the way each thinker understood the nature of biological development itself. In the final section of the paper I challenge the traditional view (dating back to Alexander's interpretation of Aristotle) that the use of automata in GA can simply be read off from their use in the de motu.

There are many things that philosophy of biology might be. But, given the existence of a professional philosophy of biology that is arguably a progressive research program and, as such, unrivaled, it makes sense to define philosophy of biology more narrowly than the totality of intersecting concerns biologists and philosophers (let alone other scholars) might have. The reasons for the success of the “new” philosophy of biology remain poorly understood. I reflect on what Dutch and Flemish, and, more generally, European (...) philosophers of biology could do to improve the situation of their discipline locally, regionally, and internationally, paying particular attention to the lessons to be learned from the “Science Wars.”.

Species are central to biology, but there is currently no agreement on what the adequate species concept should be, and many have adopted a pluralist stance: different species concepts will be required for different purposes. This thesis is a multidimensional analysis of species pluralism. First I explicate how pluralism differs monism and relativism. I then consider the history of species pluralism. I argue that we must re-frame the species problem, and that re-evaluating Aristotle's role in the histories of systematics can (...) shed light on pluralism. Next I consider different forms of pluralism: evolutionary and extra-evolutionary species pluralism, which differ in their stance on evolutionary theory. I show that pluralism is more than a debate about the species category, but a debate about which concepts are legitimate and a claim about how they interact with one another. Following that, I consider what sort of ontology is required for different forms of species pluralism. I argue that pluralists who deny the unity of biology will require a further plurality of frameworks, while those that ground their pluralism in evolution need only one framework. Finally, I consider what pluralism means for biological practice. I argue that species concepts are tools, and reflect on how pluralism can illuminate the way systematists approach the discovery of new species of yeast. Pluralism can make sense of the way species concepts are used, and can be developed to aid researchers in thinking about how to use the right tools for the right jobs. (shrink)

This dissertation is a collection of essays exploring the role of metaphor in Aristotle’s scientific method. Aristotle often appeals to metaphors in his scientific practice; but in the Posterior Analytics, he suggests that their use is inimical to science. Why, then, does he use them in natural science? And what does his use of metaphor in science reveal about the nature of his scientific investigations? I approach these questions by investigating the epistemic status of metaphor in Aristotelian science. In the (...) first essay, I defend an interpretation of metaphor as a type of heuristic reasoning: I claim that Aristotle uses metaphor to express conditions an explanation in natural science must meet if it is to explain regular, ordered change. These conditions specify the kinds of causes—particularly unmoved efficient causes—which the inquirer into nature is seeking. In the second essay, I look to Aristotle’s use of certain endoxa or common beliefs as explanatory principles in science, and show that his use of these principles is similar to his use of metaphor. In the final essay, I present a historical study of the analogy of art and nature, and I suggest that by looking to how the Greeks understood the role of inquiry in the arts, we can shed some light on Aristotle’s views concerning the method of inquiry he thinks the natural scientist should adopt.

Aristotle’s Naïve Somatism is a re-interpretation of Aristotle’s cognitive psychology in light of certain presuppositions he holds about the living animal body. The living animal body is presumed to be sensitive, and Aristotle grounds his account of cognition in a rudimentary proprioceptive awareness one has of her body. With that presupposed metaphysics under our belts, we are in a position to see that Aristotle in de Anima (cognition chapters at least) has a di erent explanatory aim in view than that (...) which the literature generally imputes to him. He is not explicating what we would call the “mental”—the private, inner realm which some take to be of a di erent kind than the physical—as most take him to be. His explanandum is content acquisition; the explanans is showing how the body becomes like various aspects of objects. Although he famously describes the mind (nous) as unmixed with the body, he is guided by functional constrains—nous cannot be limited or qualified if it is to potentially think all things. Thus, his inquiry into cognition is philosophically limited from a contemporary perspective. Aristotle is not doing philosophy of mind, for he doesn’t seem to find the “mental” philosophically perplexing. (shrink)

This dissertation explores Aristotle’s use of teleology as a principle of explanation, especially as it is used in the natural treatises. Its main purposes are, first, to determine the function, structure, and explanatory power of teleological explanations in four of Aristotle’s natural treatises, that is, in Physica (book II), De Anima, De Partibus Animalium (including the practice in books II-IV), and De Caelo (book II). Its second purpose is to confront these findings about Aristotle’s practice in the natural treatises with (...) the theoretical picture of the structure of teleological explanations gained from Aristotle’s theory of scientific demonstration. For this purpose a new interpretation of Analytica Posteriora II.11 is presented. This study thereby contributes to recent scholarship on the relation between Aristotle’s philosophy of science and his philosophy of nature, while at the same time adding to our knowledge of Aristotle’s notion of teleology in terms of its explanatory merits and limits.

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)

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.

Our purpose is to study Aristotle?s solution, in the second book of the Posterior Analytics, for the problem of the apprehension of the principles of science. We attend to the relations between the concepts of induction (epagoge) and intelligence (nous) found in the chapter 19, which seems to confirm that the acquisition of the principles is reached by a process of empirical observation. We examine the method, proposed in chapters 13 to 17, for the right formulation of definitions, which seems (...) to attribute to dialectics the task of finding the principles. Aristotle seems to indicate two different methods ? on one hand, the empirical observation followed by intelligence, on other, the dialectics ? for the apprehension of the principles. Our purpose is to study possible solutions for the problem of the concurrence between these two methods in order to refute as much a strictly empiricist interpretation as a strictly dialectical one.

My dissertation explores some issues of Aristotle’s philosophy, regarding the functionalist interpretation developed by Hilary Putnam and Martha C. Nussbaum as a valuable starting point. In Chapter One, I analyze some families of interpretations of Aristotle’s “psuchology” proposed in the second half of the 20th century in the context of the philosophy of mind. I show how some aspects of Aristotle’s thought, which are correctly grasped by the dualistic as well as by the physicalist interpretation, are later resumed and harmonized (...) by functionalism into a coherent doctrine. In Chapter Two it is worth to set out an analysis of Aristotle’s hylomorphism. I take into account homonymy, which is traditionally conceived as being in conflict with hylomorphism. I show not only how homonymy is rather a consequence of hylomorphism, but also how it allows to highlight that hylomorphism, if properly conceived, should be regarded as an ontological thesis with predicative consequences. In this regard, I suggest my own definition of hylomorphism. In Chapter Three, I take into account Aristotle’s final causation, comparing it with contemporary naturalism. I hold that teleology demonstrates Aristotle’s anti-reductionism and, in particular, the fact that he attributes causal efficacy to natural forms and ends. I criticize functionalism for having regarded Aristotle’s formal and final causes as being just explanatory, whereas, on the contrary, Aristotle conceives such explanatory character to derive from their genuine causal role. I formulate my own position, which I label as “logical compatibilism”. I hint at how the functional analysis of living organism may establish some points of contact between Aristotle’s and Darwin’s analysis. I recognize that functionalism correctly grasps the functional roles Aristotle attributes to matter and form and that it translates such an account in a valuable philosophical doctrine. Nevertheless, functionalism confines itself within the framework of contemporary philosophy of mind and fails to comprehend Aristotle’s anti-reductionist naturalism as regards biological life and nature in general.

Species pluralism allows for multiple species concepts. Given the overwhelming number of such concepts, this seems like an obvious interpretation of how `species' is used in contemporary biology. But why has it taken so long for this approach to be considered? I argue that part of the reason pluralism was overlooked due to the widespread use of a particular rhetorical strategy developed by Ernst Mayr. This strategy provided a framework for debates about the correct conception of species. That is, the (...) strategy offered a means of comparing modern concepts with a monistic-essentialist understanding of species. I ask what would happen if we replaced this concept with Aristotle's own pluralist-essentialist understanding of species. As recent scholarship shows, Aristotle's philosophy of biology allows for an approach to classification that is in practice highly pluralistic. From this new framework we can understand what sort of assumptions are at stake between modern forms of species pluralism. My analysis shows that the essentialist story told by Mayr and others left us asking the wrong questions about how to conceive of species in an evolutionary world. Having a deeper understanding of Aristotle's approach to the classification of animals allows us to shift focus from the so-called species problem in order to raise four issues that are relevant to current debates. These are questions about: the explanatory power of taxonomic ranks, the importance of the species category problem, whether species are constituted by intrinsic or extrinsic properties, and how to interpret the ``cross-cutting'' metaphor endemic to the pluralist literature. In order to get to these questions I will first explain what sort of claim species pluralism is at the most general level, and a gloss on the standard interpretation of the historical shift from species monism to species pluralism.

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)
