A presentation showing how the statements which relate to microphysical objects as they are different from the statements of classical mechanics is made. The determinism of classical and of quantum-mechanical theories is qualified. A (crucial) distinction between causality and determinism is given. Detailed analyses of diffraction as a result of single and double-slit demonstrations point to paradoxes arising from the use of particle or wave models, respectively, for photons and electrons. The compromising wave-packet model is underscored. The meanings for the (...) Psi-function and for |ψ|2 are presented, with an explanation of the limitations that arise from giving an interpretation of |ψ|2 as a probability. The meaning of ψ -waves is analyzed. A case is made for the ψ -function's describing a well-ordered list of betting odds, based on previous statistical experiences, for the different results of specific experiments of a microscopic object of study with macroscopic apparatus. The Schrödinger wave equation is evaluated for meaning and judged as a deterministic expression. (shrink)

This book aims to answer two main questions about Aristotle’s theory of causality and causal explanation, especially in relation to natural science: (1) How does he answer the main philosophical questions about causes to which he thinks his predecessors’ answers are flawed? (2) How do his answers bear on the main questions we confront in thinking about causality in general? The texts that deal with causality directly are analyzed against the background of his criticisms of his predecessors (...) and his broader views about explanation, highlighting their theoretically important commitments. This allows us to reveal the conceptual architecture of his theory. The basic theory is then applied to two questions about causality, one metaphysical and one epistemological. The metaphysical question is how to account for the relation between causes and what they cause, in light of a fundamental tension between different desiderata for causal explanations. Aristotle’s answer is pluralistic: he does not think that there is one metaphysical relationship between causes and what they cause even within a given mode of causality. The epistemological question asks how we grasp causes, and grasp them in a way that yields scientific understanding. Aristotle’s answer is again a pluralist one: metaphysically different phenomena demand different cognitive resources, and some are more accessible than others. Nevertheless, there is a discernible path from simpler to more sophisticated types of cognitive grasp on causality, in such a way that Aristotle can plausibly satisfy the epistemological constraints he thinks his predecessors cannot. Aristotle thus aims to provide a non-reductionist account of causality that still leaves room for a substantive conception of understanding in natural science. (shrink)

Given that they are chance events, there can be no scientific demonstration or knowledge of monsters. There are still, however, many recognizable elements of scientific explanation in Aristotle's Generation of Animals Book IV chapter 4. What happens in cases of monsters and deformities occurs in the process of generation, and there is much that we can know scientifically about this process—working from the animal’s essential attributes outward to factors that influence these processes. In particular, we find Aristotle (...) looking for and investigating whether “for the most part” correlations are causally relevant and linked to essence. Even though the birth of monsters is scientifically inexplicable, the features of animals that tend to produce them can be known about. I will explain how it is that producing more than one offspring per birth is a knowable feature of a kind. This feature, along with others, can then give us a much better grasp on what happens in particular instances of monstrous birth. (shrink)

Diogenes subscribes to a principle that, roughly, causal interaction and change require a certain sort of uniformity among the relata. Attending to this principle can help us understand Diogenes's relationship to the superficially similar Anaximenes without insisting, as some do, that Diogenes must be consciously responding to Parmenides. Diogenes is distinctive and philosophically interesting because his principle combines two senses of ‘archê’ (principle, starting-point), namely, the idea of source or origin and that of underlying (material) principle, and gives the (...) rudiments of an argument for associating the two, by which Aristotle may have been influenced. Diogenes’s principle and its deployment in biological explanations thematized a concern that Aristotle at least partially shared, and which led him to appeal, as Diogenes is said to have done, to pneuma (breath, air).

I discuss an important feature of the notion of cause in Post. An. 1. 13, 78b13–28, which has been either neglected or misunderstood. Some have treated it as if Aristotle were introducing a false principle about explanation; others have understood the point in terms of coextensiveness of cause and effect. However, none offers a full exegesis of Aristotle's tangled argument or accounts for all of the text's peculiarities. My aim is to disentangle Aristotle's steps to show (...) that he is arguing in favour of a logical requirement for a middle term's being the appropriate cause of its explanandum. Coextensiveness between the middle term and the attribute it explains is advanced as a sine qua non condition of a middle term's being an appropriate or primary cause. This condition is not restricted either to negative causes or to middle terms in second‐figure syllogisms, but ranges over all primary causes qua primary. (shrink)

What precisely does aristotle mean when he asserts that something is (or comes to be) "for" "the" "sake" "of" something? I suggest that the answer to this question may be found by examining aristotle's position on the problem of reduction in biology, As it arises within his own scientific "and" "philosophical" context. I discuss the role of the concepts of "nature" and "potential" in aristotelian scientific explanation, And reformulate the reduction problem in that light. I answer the (...) main question by establishing that aristotle holds an "irreducibility" thesis in regard to the generation and development of a living organism, And that this thesis is the core of his conception of final causality. I conclude by arguing that aristotle's teleology is fundamentally "empirical" in character, And not an a priori doctrine brought "to" the study of nature. (shrink)

Since its origins as a distinct philosophical discipline during the first quarter of the present century, philosophy of science has been largely a matter of logical analysis. Only in relatively recent times have the historically minded philosophers attacked the logical empiricist account of the scientific enterprise. Among the pioneers of this revolution, however, Kuhn, along with Popper and Feyerabend, have also challenged the idea that a linear growth in scientific knowledge is either possible or desirable. Though partial to the historical (...) approach, Wallace will not accept this negativistic thesis. On the other hand, his conviction that most scientists are realists at heart makes him reject the positivistic account of science proposed by Duhem, Mach and the Vienna Circle. Science, he claims, aims at discovering the truth about the world. It is not content simply to describe how things are, but wants to know why. Now it is in their search for causes that scientists reveal their realistic convictions. And it is because science throughout its long history has made causal explanations the paradigm of scientific knowledge that its growth is not the haphazard or irrational sort of thing that Kuhn envisions. In this first of a proposed two-volume work, Wallace traces the origins of this paradigm to Aristotle’s Posterior Analytics. Part I, ‘Medieval Science', sketches the influence of this work on medieval scientists at the universities of Oxford, Paris and Padua from the 13th to the 16th centuries. Part II, entitled ‘Early Classical Science', shows how the earlier paradigm continues to influence such men as Gilbert, Kepler, Galileo, Harvey and Newton. Both historians and philosophers can profit from this original and controversial study. Even those who would not accept the author’s thesis that "the reconstruction of contemporary philosophy of science necessitates a return to some of the values of medieval and early classical science" will be grateful for the great amount of factual information and wealth of primary source material the book provides. We look forward to the publication of the companion volume on "Classical and Contemporary Science."—A. B. W. (shrink)

I will argue for the similarity between some aspects of Aristotle’s doctrine of causes and a particular kind of interventionist theory of causality. The interventionist account hypothesizes that there is a connection between causation and human intervention: the idea of a causal relation between two events is generated by the reflection of human beings on their own operating. This view is remindful of the Aristotelian concept of αἴτιον, which is linked to the figure of the αἴτιος, the person (...) who is responsible of an action. Aristotle conceives of the efficient cause as the active element which, in the φύσις, gives rise to movement and imposes the form, in analogy with the active element that in τέχνη operates the production: the craftsman. This analogy suggests that Aristotle conceives of the causation on the basis of the human ability to modify the environment with aims. Within the debate on the manipulative theory the classical accounts worked out by Collingwood, Gasking and von Wright have been recently criticized by Woodward. von Wright’s reductive account explains causation on the basis of human free action, while Woodward regards this reduction as a dangerous move which makes causal explanations too much anthropomorphic. I will show that Aristotle’s doctrine of causes is more similar to von Wright’s account and that the Aristotelian analysis of becoming supports von Wright’s reductive interventionism against Woodward’s criticism. Furthermore, I will draw a comparison between interventionism and dispositionalism, where the latter is another contemporary account of causation that claims Aristotelian roots. (shrink)

In On the Parts of Animals, Aristotle develops his systematic principles for biological investigation and explanation, and applies those principles to explain why the different animals have the different parts that they do. This new translation and commentary reflects the subtlety and detail of Aristotle's reasoning.

Philosophers have discussed the relationship of cause and effect from ancient times through our own.Prior to the work of Niels Bohr, these discussions presupposed that successful causal attribution implies explanation.The success of quantum theory challenged this presupposition.Bohr introduced a principle of complementarity that provides a new way of looking at causality and explanation. In this succinct review of the history of these discussions, John Losee presents the philosophical background of debates over the cause-effect relation.He reviews the positions (...) of Aristotle, Rene Descartes, Isaac Newton, David Hume, Immanuel Kant, and John Stuart Mill.He shows how nineteenth-century theories in physics and chemistry were informed by a dominant theory of causality and how specific developments in physics provided the background for the emergence of quantum theory. Problems created for the "causality implies explanation" thesis by the emergence of quantum theory are reviewed in detail.Losee evaluates Bohr's proposals to apply a principle of complementarity within physics, biology, and psychology.He also discusses the feasibility of using complementarity as a principle of interpretation within Christian theology.This volume, which includes an in-depth index, is an essential addition to the libraries of advanced undergraduate and graduate students, philosophers, and those interested in causality and explanation.

Aristotle is without question the founder of the science of biology. In his treatise On the Parts of Animals, he develops his systematic principles for biological investigation, and explanation, and applies those principles to explain why the different animal kinds have the different parts that they do.

In this chapter, Hankinson discusses Aristotle's conceptions of nature, change, and potentiality; the four causes, spontaneity, and chance; teleology and hypothetical necessity; and also Aristotle's account of action, freedom, and responsibility. The choice facing Greek philosopher‐scientists is simple: show how a structured, regular world could arise out of undirected processes, or pursue a teleological explanation, insisting on the activity of divine intelligence in the cosmos. Aristotle, Hankinson writes, pursues a middle way between these options, although, ultimately, (...) Aristotle takes the whole structure of the cosmos to be teleologically organized. Aristotle rejects Plato's metaphysics of perfect hypostasized forms and divinely directed teleology: relying heavily on his concept of phusis or nature, Aristotle makes teleology an internal principle governing the development of natural objects. Aristotle distinguishes four causes or causal factors in explanation: matter, form, agent, and end, and he distinguishes sharply between regular natural events that can be explained by means of these causes, and chance events, which do not admit full explanation.

The legitimacy of going back to the classical view of God’s action in the world based on the list of causes and understanding of chance in the works of Aristotle and Aquinas – in the context of contemporary science – seems to depend on whether there is a space for causal analysis within the current models of scientific explanation. This article offers a brief account of the path leading to negation and rediscovery of the importance of causality (...) in scientific explanation and reintroduces the semicausal position of the prominent philosopher of science, Mario Bunge, who treats causation as one of several categories of determination. The diversity of the categories he lists finds analogy in the commonly accepted pluralist approach to the search of the model which adequately describes the practice of scientific research. What is more, the same diversity of the categories of determination opens the way back to the classical Aristotle’s fourfold account of causation and his understanding of chance. This fact allows us, in turn, to defend the contemporary version of the classical notion of divine action against the accusation of methodical error in the form of imposing the notion of the ancient categories of causality on the results of contemporary scientific research, which notion, as some maintain, has little in common with the models of explanation currently accepted in natural sciences.

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)

In the first part of this article, I argue that Christopher Megone's natural-kind interpretation of Aristotle's argument that "the function of a human being is reason" does not resolve major puzzles about the argument, specifically the puzzles of why a human being has a function and why reason is that function. I attempt to resolve these puzzles by supplementing the natural-kind account with the doctrine that reason is the master regulatory natural function by which individuals enter into social life. (...) In the second half, I critique Megone's value account of function and argue for a nonevaluative, causal-explanatory account of function and teleological explanation. (shrink)

Monte Johnson examines one of the most controversial aspects of Aristiotle's natural philosophy: his teleology. Is teleology about causation or explanation? Does it exclude or obviate mechanism, determinism, or materialism? Is it focused on the good of individual organisms, or is god or man the ultimate end of all processes and entities? Is teleology restricted to living things, or does it apply to the cosmos as a whole? Does it identify objectively existent causes in the world, or is it (...) merely a heuristic for our understanding of other causal processes? Johnson argues that Aristotle's aporetic approach drives a middle course between these traditional oppositions, and avoids the dilemma, frequently urged against teleology, between backwards causation and anthropomorphism. Although these issues have been debated with extraordinary depth by Aristotle scholars, and touched upon by many in the wider philosophical and scientific community as well, there has been no comprehensive historical treatment of the issue. Aristotle is commonly considered the inventor of teleology, although the precise term originated in the eighteenth century. But if teleology means the use of ends and goals in natural science, then Aristotle was rather a critical innovator of teleological explanation. Teleological notions were widespread among his predecessors, but Aristotle rejected their conception of extrinsic causes such as 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. Aristotle's use of ends 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. Johnson addresses these misconceptions through an elaboration of Aristotle's methodological statements, as well as an examination of the explanations actually offered in the scientific works.

Human beings, according to Aristotle, are not the only political animals. Bees, wasps, ants and cranes are the other political species mentioned by Aristotle in the History of Animals. Politics, I, 2 confirms this point and makes the additional statement that human beings, if not the only political animals, are nevertheless more political than the other political animals. There has been a traditional scholarly agreement that the capacity for rational speech is the reason why human beings are more (...) political. This traditional view seems to have some support from the same chapter of Politics, where Aristotle addresses, right after having stated that human beings are more political, the role of language in human beings’ political life. This paper contests this traditional view about language and claims that it is the more political character of human beings which explains the political role of language and not vice versa. -/- .

Aristotle's remarks about the differences between the sexes have become infamous for their implications for the social status of women. In his observations on female biology, Aristotle claims that "the female nature is, as it were, a deformity." In describing women's role in the public sphere, he claims that women are naturally subordinate because, while they possess a deliberative faculty, that capacity is "without authority." While both claims express the "inferiority" of female bodies/women relative to male bodies/men, it (...) is not self-evident that the defects Aristotle identifies in female biology have cognitive or moral manifestations that would justify the rule of men over women in political life. Marguerite Deslauriers here aims to construct a coherent picture of Aristotle's views on sexual and gender-based difference from these remarks and to show the extent to which his views on female biology and women's role in politics are causally connected. Without exculpating Aristotle from charges of misogyny, Deslauriers contextualizes his explanations of the role and origin of female animals in his biology and the role of women in his political philosophy; she shows how Aristotle developed these views and the importance they hold for his wider philosophical commitments. She then explores how Aristotle might have seen the link between the physiology of sex and the bearing it has on political life. She ultimately argues that in Aristotle's conception of sexual difference in biology and politics, there is a tension between his view of the inferiority of female bodies and women and his commitment to the idea that females and women are valuable both for generation and for the political life characteristic of human beings. In this tension she finds a difference between Aristotle and his predecessors: while previous accounts associate sexual difference with affliction, Aristotle sees sexual difference as a benefit, both to a species and a political community. This volume will be of interest to philosophers and students interested in ancient philosophy, feminist philosophy, as well as those studying moral and political philosophy. (shrink)

In Posterior Analytics II 16-17, Aristotle seems to claim that there cannot be more than one explanans of the same scientific explanandum. However, this seems to be true only for “primary-universal” demonstrations, in which the major term belongs to the minor “in itself” and the middle term is coextensive with the extremes. If so, several explananda we would like to admit as truly scientific would be out of the scope of an Aristotelian science. The secondary literature has identified a (...) second problem in II 16-17: the middle term of a demonstration is sometimes taken as the definition of the minor term (the subject), other times as the definition (or the causal part of the definition) of the major (the demonstrable attribute). I shall argue that Aristotle’s solution to the first problem involves showing that certain problematic attributes, which appear to admit more than one explanation, actually fall into the privileged scenario of primary-universal demonstrations. In addition, his solution suggests a conciliatory way-out to our second problem (or so I shall argue): the existence of an attribute as a definable unity depends on its subject having the essence it has, which suggests that both the essence of subjects and the essence of demonstrable attributes can play explanatory roles in demonstrations.

Aristotle is often considered to have a very pessimistic view about what histories can tell us, considering them too particular and lacking the generality required for scientific knowledge. Most importantly, they are considered to lack causal explanations. I argue against this view and instead that Aristotle considers histories to provide a highly practical level of knowledge. Histories can provide instances of both accidental and hypothetically necessary causation. I draw on the Athenian Constitution and the Constitution of the (...) Spartans to show that the historiai which were written under Aristotle’s direction display these causal explanations. While these explanations are still not at the level of generality characteristic of the most rigorous forms of epistemē, the causal pictures presented are still rich enough to provide valuable insights for both the politician and the political scientist.

At some point in the Incessu Animalium, Aristotle appeals to some geometrical claims in order to explain why animal progression necessarily involves the bending (of the limbs), and this appeal to geometrical claims might be taking as violating the recommendation to avoid “kind-crossing” (as found in the Posterior Analytic). But a very unclear notion of kind-crossing has been assumed in most debates. I will argue that kind-crossing in the Posterior Analytics does not mean any employment of premises from a (...) discipline other than that to which the explanandum belongs. Kind-crossing was meant to cover a specific sort of employment of premises from a different discipline, namely, the case in which premises from a discipline X are taken as the most important explanatory factor that delivers the fullest appropriate explanation of an explanandum within discipline Y. If this is so, the employment of geometrical premises in the Incessu Animalium is not an instance of the prohibited kind-crossing, but something that is in line with the theory of the Posterior Analytics.

Such diverse questions are unified by the fact that they are all demands for explanation, for an account of the world that will render it amenable to prediction and control. (shrink)

In the field of philosophy, Plato's view of rhetoric as a potentially treacherous craft has long overshadowed Aristotle's view, which focuses on rhetoric as an independent discipline that relates in complex ways to dialectic and logic and to ethics and moral psychology. This volume, composed of essays by internationally renowned philosophers and classicists, provides the first extensive examination of Aristotle's Rhetoric and its subject matter in many years. One aim is to locate both Aristotle's treatise and its (...) subject within the more general context of his philosophical treatment of other disciplines, including moral and political theory as well as poetics. The contributors also seek to illuminate the structure of Aristotle's own conception of rhetoric as presented in his treatise. The first section of the book, which deals with the arguments of rhetoric, contains essays by M. F. Burnyeat and Jacques Brunschwig. A section treating the status of the art of rhetoric features pieces by Eckart Schütrumpf, Jürgen Sprute, M. M. McCabe, and Glenn W. Most. Essays by John M. Cooper, Stephen Halliwell, and Jean-Louis Labarrière address topics related to rhetoric, ethics, and politics.

In this paper we argue that Aristotle operates with a particular theoretical model in his explanation of animal locomotion, what we call the ‘centralized incoming and outgoing motions’ model. We show how the model accommodates more complex cases of animal motion and how it allows Aristotle to preserve the intuition that animals are self-movers, without jeopardizing his arguments for the eternity of motion and the necessary existence of one eternal unmoved mover in Physics VIII. The CIOM model (...) helps to elucidate Aristotle’s two central yet problematic claims, namely that the soul is the efficient cause of animal motion and that it is the internal supporting-point necessary for animal motion. Moreover, the CIOM model helps us to explain the difference between voluntary, involuntary and non-voluntary motions, and to square Aristotle’s cardiocentrism with his hylomorphism, but also, more generally, it provides an interesting way of thinking about the place of intentionality in the causal structure of the world.

This is a translation, made by myself, of the paper to be published in Portuguese in the journal Discurso, 2020, in honour of the late professor Oswaldo Porchat. I discuss what Aristotle was trying to encode when he said that the object of scientific knowledge is necessary, or that what we know (scientifically) cannot be otherwise etc. The paper is meant as a continuation of previous papers—orientated towards a book on the Posterior Analytics—and thus does not discuss in much (...) detail key passages, as the very definition of scientific knowledge in APo I.2, or passages from APo I.4 and I.6 (for these, I refer to my previous papers). This paper is mainly focused on Aristotle’s references to his notion of scientific knowledge both in other passages from the APo and in other treatises. I intend to show that there is a progressive, intrinsic relation between the two requirements by which scientific knowledge is defined. It is not true that each of these requirements stems from a different source. The Causal-Explanatory requirements gives Aristotle the general heading. Then, the Necessity Requirement ranges over the explanatory relation between explanans and explanandum and thereby specifies what sort of cause is sctricly required for having scientific knowledge of a given explanandum. Now, Aristotle was also concerned with the necessary truth of the elemental predications that constitute a demonstration. My claim that the Necessity Requirement ranges over the explanatory relation does not ignore that concern, and does not deny it. My claim is that Aristotle’s main focus, and main concern, consists in stressing that the explanatory factor to be captured in scientific knowledge of a given explanandum is such that cannot be otherwise.

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.

I defend an interpretation of Aristotle’s _Posterior Analytics _Book I which distinguishes between two projects in different passages of that work: to explain what a given science is and to explain what properly scientific knowledge is. I present Aristotle’s theory in answer to ii, with special attention to his definition of scientific knowledge in 71b9-12 and showing how this is developed on chapters 1.2-9 and 1.13 into a solid Theory of Scientific Demonstration. The main point of this theory (...) is that demonstrations need to capture relevant explanations. Some formal requirements of the demonstration are unfoldings of the main project, 1.e., to capture and present properly relevant causal-explanatory relations. (shrink)

In this article I defend an account of Meteorology IV as providing a material-level causal account of the emergence of uniform materials with a wide range of dispositional properties not found at the level of the four elements—the emergence of material complexity. I then demonstrate that this causal account is used in the Generation of Animals and Parts of Animals as part of the explanation of the generation of the uniform parts (tissues) and of their role in (...) providing nonuniform parts (organs) with the dispositional properties needed to fulfill their functions.

Broadly speaking, ancient concepts of causality in terms of explanatory priority have been contrasted with modern discussions of causality concerned with agents or events sufficient to produce effects. As Richard Taylor claimed in the 1967 Encyclopedia of Philosophy, of the four causes considered by Aristotle, all but the notion of efficient cause is now archaic. What we will consider here is a notion even less familiar than Aristotelian material, formal, and final causes—what we will call 'demonstrational causality'. Demonstrational causality (...) refers to the dependence of the conclusion on the premises of a demonstration. Here, if ever, we have a case of explanational priority, since among other things what is required of the premises is that they be better known or more manifest than the conclusion. But, oddly enough, Aristotle and his medieval commentators describe demonstrational causality in the same terms as efficient causality. Aristotle speaks of the conclusion as an "effect" of the premises; his commentators speak of the "sufficiency" of first principles or axioms in producing the conclusion. (shrink)

It is common to think of essence along modal lines: the essential truths, on this approach, are a subset of the necessary truths. But Aristotle conceives of the necessary truths as being distinct and derivative from the essential truths. Such a non-modal conception of essence also constitutes a central component of the neo-Aristotelian approach to metaphysics defended over the last several decades by Kit Fine. Both Aristotle and Fine rely on a distinction between what belongs to the essence (...) proper of an object and what merely follows from the essence proper of an object. In order for this type of approach to essence and modality to be successful, we must be able to identify an appropriate consequence relation which in fact generates the result that the necessary truths about objects follow from the essential truths. I discuss some proposals put forward by Fine and then turn to Aristotle’s account: Aristotle’s central idea, to trace the explanatory power of definitions to the causal power of essences has the potential to open the door to a philosophically satisfying response to the question of why certain things are relevant, while others are irrelevant, to the nature or essence of entities. If at all possible, it would be desirable for example to have something further to say by way of explanation to such questions as ‘Why is the number 2 completely irrelevant to the nature of camels?’.

Rom Harré's generative account of causality has been drawn on heavily by advocates of critical realism. Yet Harré argues that critical realists often exaggerate the extent to which powerful causal explanations of social phenomena can be developed. Certain proponents of critical realism have responded to Harré's criticisms by suggesting that it is useful to consider the relevant issues in relation to the familiar Aristotelian classification of four causes. In this paper I contribute to this debate and pursue a similar (...) strategy. The paper adds to existing contributions in two ways. Firstly, I outline how Harré sees his generative account of causality as linking up with Aristotelian themes. It emerges that Harré at times conceives of his generative theory as part of an alternative to the Aristotelian system while at other times he draws connections between it and a reformulated account of formal causality. Secondly, I argue that when we consider the positions of Harré and proponents of critical realism on the scope of causal explanation in the social realm in relation to the interpretation of final causes offered by another philosopher profoundly influenced by the Aristotelian tradition, namely Charles Peirce, we can see both as limited in certain respects.

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.

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)

[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.

Aristotle's view of the interdependency of explanation and definition rests on a metaphysical thesis: essences are what determine the nature of kinds in such a way as to make their causal structure completely intelligible to us and to locate them in their own distinctive niche in a nexus of genera and species. We can rationally base our understanding of the first principles of science on our understanding of this causally based pattern of kinds. The world, so understood, (...) contains its own intelligible structure, which Aristotle identifies with the Active Intellect. (shrink)

It is now a widespread opinion among interpreters that Aristotle’s History of Animals is not a mere collection of empirical data but has its own theoretical framework; however, there is still disagreement as to exactly what this framework is. To address the problem, the article analyzes in detail the diairetic schemes of HA I 1, attempting to overturn the common opinion that this chapter is a mere expository introduction to the study of animals’ differences. On the contrary, it will (...) be shown that in this chapter Aristotle not only applies the method of ‘multiple division’ theorized in Parts of Animals I 2–4, but also uses dividing criteria that are informed by his causal theory and his hylomorphist ontology. This analysis will therefore lead to the more controversial conclusion that HA is not an ‘early’ work by Aristotle but a mature treatise with its own specific theoretical aim: the aitiological explanation of the anatomical, eco-physiological and ethological differences among animals.

Aristotle seeks to resolve the problems raised in Posterior Analytics B.3–7 by arguing that our practices of definition and explanation are interdependent. It is not possible to define kinds without appeal to their causal structure, nor is it possible to single out the relevant causal structure without appeal to what is required for good definition. This is why Aristotle holds that the answer to the questions, ‘What is F?’ and ‘Why is F as it is?’ (...) are the same. Neither definition nor explanation can be completed without assistance from the other. (shrink)

During the past three decades, Aristotle studies have been significantly influenced by a series of ground-breaking investigations of the zoological works, especially the Historia animalium. As a result, contemporary Aristotle scholars have developed a clearer and more consistent interpretation of the zoology and have demonstrated its consonance with Aristotle’s logic and metaphysics. This revolution in Aristotle studies was anticipated by the medieval natural philosopher Albertus Magnus. As the first thinker since Theophrastus to pursue an Aristotelian research (...) program in the life sciences, he interpreted Aristotle’s animal histories as a series of pre-demonstrative researches preparatory to causal explanation as prescribed in the Posterior Analytics and the Topics. The medieval anticipation of these recent developments in Aristotle studies provides a compelling comparison of the interpretation of Aristotle now and then. (shrink)

The present paper, taking as a point of departure Aristotle’s dispute with the ancient physicalists in Physics II.8-9 about the role of the final cause in nature, examines the context of the problem, his theory of the causes. Aristotle assumes an analogy between nature and craft and takes the production of artifacts to be paradigmatic. With these assumptions as guiding principles, the paper attempts to motivate his causal theory and propose what may be called a “logic” of (...) the causes. It examines artefactual coming-to-be more closely, focusing on the aspects of Aristotle’s account that are highlighted in his explanation of natural coming-to-be: the basic character of the causes, the peculiar distinction between the causes and the accompanying the deeper coincidence among three of them, the complementarity between the final and moving causes, the nature and role of desire in coming-to-be, and the primacy of form. It introduces the notion of a trans-temporal objective whole and shows the need to consider the full whole — which includes the entire process of coming-to-be together with its source — as the proper context for a full understanding of coming-to-be. It also points out the importance of the distinction between the objective and subjective perspectives, especially useful in understanding final causality. (shrink)

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...

Books in this series have a first part providing an introduction to and history of a problem and a second part which builds up to the author's own views. For his historical treatment of the problems of explanation Ruben selects Plato, Aristotle, Mill, and Hempel. The space devoted to Plato and Aristotle is rather unexpected, but as with the other figures considered Ruben focuses on themes of relevance to current debates. Thus the discussion of Plato is largely (...) on whether two "opposites" can explain the same thing and whether the same thing can explain two opposites. On Ruben's intricate analysis, the issue has a bearing on probabilistic dependency theories of explanation and on whether causes need be either necessary or sufficient for their effects. The discussion of Aristotle introduces among other things the idea that an adequate theory of explanation will have metaphysical underpinnings; it should, in other words, fit "what we think the world is like". Ruben is sympathetic to this idea and pursues it more fully later. Mill figures largely as a precursor of Hempel, but there is an interesting discussion of the relation between Mill's view that explanations are deductive arguments and his rather peculiar thesis that deduction is not "real" inference. Not surprisingly, the Hempelian account forms the main backdrop to Ruben's constructive analysis. Among the main topics discussed are the ontology of explanation, the standard counterexamples to the Hempelian account, the introduction of a causal condition into the analysis of explanation, the role of laws in relation to explanation, whether explanations are arguments, and whether all explanation is causal. The discussion is clear and thorough all the way through. In dealing with Ruben skillfully works up to the view that "facts explain facts only when the features and the individuals the facts are about, are appropriately conceptualized or named". This brings out the sense in which explanation is "epistemological." is crucial to the ensuing discussion, since if, as Ruben suggests, we "put the 'cause' back into 'because'" to deal with, the idea that laws must figure in explanantia, and the idea that explanations must be arguments, seem less compelling. Still, a further question is whether all singular explanations are causal. Ruben delivers a negative answer. There are explanatory identities. "A particular's having a property, described or conceptualized in one way, can explain the same particular's having the same property, described or conceptualized in another way". There is no self-explanation here given the favored ontology of explanation. There would be self-causation if such explanations were causal. So they are not causal. But even noncausal explanations explain something by "showing what is responsible for it or what makes it as it is". That, Ruben concludes, is what explanation is all about. (shrink)

Aristotle claims in Metaphysics Z.17 that form is both a cause and principle of c‐substances. In this chapter, Wedin argues that the explanatory, or causal, role of form is in the background of the entire discussion, and indeed directs much of the argumentation of Metaphysics Zeta. Form is the cause of some matter being a unity and not a heap, because form alone explains how the material parts of a thing are united in a single whole. Wedin draws (...) together the main results of the preceding investigation of Zeta—that form is essence, that form must not contain matter or actual parts, and that form must not be a certain kind of universal—and he argues that these constraints on form are designed to serve the explanatory role that Aristotle explicitly gives to form in Z.17. Wedin emphasizes that the notions isolated in the examination of the earlier chapters, such as the purity of form, weak proscription, and dual complexity, each contribute to the account of form as the explanatory principle of c‐substance.
