Aristotle: Causation

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 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)

This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

I have two aims in this paper. First, I argue that, in Aristotle’s theory of the four causes, there is a basic and common feature by which all causes are causes: they all work in a triadic framework in which they explain why a given attribute holds of a given underlying thing. Secondly, I argue against a version of “compatibilism” according to which each kind of cause is complete in its own domain and does not compete with any other kind. (...) I claim that there are priority relations according to which some kinds of cause are subordinated to others, even if these relations do not hold in every cases. (shrink)

I discuss in this paper Aristotle’s definition of nature in Physics 192b 20-23. I intend to prove that this definition has to be taken as a set of three (not only two) conditions: the first condition just establishes that nature is a sort of cause; the second condition concerns the relationship between nature and the natural thing that has it as a cause; the third condition concerns the relationship between nature and the properties that natural things have from nature’s causality.

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)

This paper discusses whether there is room for knowledge of causal relations between events in Aristotle's theory of science as developed in the Posterior Analytics. My focus is on Aristotle's analysis of the fourth sense of kath' hauto or per se predication.

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

We take as an object of study the text De generatione et corruptione (GC) 2. 10 to establish the use of scientific demonstration. Aristotle states in GC 1 the principles of generation but then he builds genuine scientific demonstrations basing precisely on those principles. We will reconstruct a specific passage of GC 2. 10 in order to defend the hypothesis of the real use of scientific demonstration in scientific treatises. Par- ticularly, in the frame of the four Aristotelian causes, we (...) show that this demonstration makes explicit the efficient cause of the phainomena of generation and corruption. (shrink)

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

Ao desenvolver sua teoria causal no livro II da Física, Aristóteles explica e exemplifica cada uma das causas separadamente, como se existissem por si só. Mas, ao se fazerem presentes nos entes, encontram-se ligadas uma às outras, expressando uma relação de subordinação entre si. Cada ente possui uma causa de um dos quatro tipos em sua formação, sendo uma causa material, uma formal, uma eficiente e uma final. Desse modo, meu objetivo é apresentar como as causas existem nos entes a (...) partir de seus diferentes modos de subordinações, visando, principalmente, como cada uma se relaciona com causa final.

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)

Modern philosophy is, for what appear to be good reasons, uniformly hostile to sui generis final causes. And motivated to develop philosophically and scientifically plausible interpretations, scholars have increasingly offered reductivist and eliminitivist accounts of Aristotle's teleological commitment. This trend in contemporary scholarship is misguided. We have strong grounds to believe Aristotle accepted unreduced sui generis teleology, and reductivist and eliminitivist accounts face insurmountable textual and philosophical difficulties. We offer Aristotelians cold comfort by replacing his apparent view with failed accounts. (...) And so we ought to admit Aristotle’s prima facie commitments and deal with — if not accept — the consequences. (shrink)

A presente dissertação se propõe analisar, a partir do pensamento aristotélico, a noção de causalidade acidental no tocante a sua fusikh; ejpisthvmh. Aristóteles, buscando encontrar as causas que explicam o vir-a-ser dos seres por natureza, se deparou com os acidentes e, não podendo deixar nenhum evento sem causa, postulou a existência de causas acidentais. Apesar de o acidente não ser objeto de ciência, a possibilidade de seu vir a ser salvaguarda o mundo da fuvsi" de um determinismo causal absoluto: eis (...) o papel e a importância de uma causalidade acidental no mundo físico aristotélico.

Frente a quienes sostienen una incompatibilidad entre historia de la filosofía y filosofía, en cuanto plantean una disyuntiva entre una práctica descriptiva y una argumentativa, en este trabajo nos proponemos mostrar, examinando la labor histórico-filosófica de Aris- tóteles, que esa disyuntiva no es excluyente. Para ello, en primer lugar, examinaremos algunos pasajes de su obra en los que ofrece indicaciones metodológicas que permiten comprender la doble función que cumplen las exposiciones críticas de los filósofos precedentes en la constitución misma de (...) su filosofía. En segundo lugar, ilustraremos el tipo de argumentación aristotélica a través del análisis de las críticas que dirige a las Ideas platónicas como causas. Contra Platón, Aristóteles establece que, para dar cuenta de la ingenerabilidad e incorruptibilidad de las formas, no es necesario caracterizarlas como entidades separadas de la materia y del movimiento. Basta asegurar la eternidad de la forma a través de su reproducción en otros individuos de la misma especie. Tal análisis nos permite concluir, finalmente, que filosofía o historia de la filosofía constitu- yen una falsa disyuntiva en Aristóteles, por lo que el examen dialéctico de las doctrinas precedentes es un método adecuado de indagación filosófica.

Aristotle argued that in theory one could acquire knowledge of the natural world. But he did not stop there; he put his theories into practice. This volume of new essays shows how Aristotle's natural science and philosophical theories shed light on one another. The contributors engage with both biological and non-biological scientific works and with a wide variety of theoretical works, including Physics, Generation and Corruption, On the Soul, and Posterior Analytics. The essays focus on a number of themes, including (...) the sort of explanation provided by matter; the relationship between matter, teleology, and necessity; cosmic teleology; how an organism's soul and faculties relate to its end; how to define things such as sleep, void, and soul; and the proper way to make scientific judgments. The resulting volume offers a rich and integrated view of Aristotle's science and shows how it fits with his larger philosophical theories. (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)

This MA thesis investigates Aristotle's natural teleology, its presuppositions and implications. In order to achieve a better understanding of his theory, a study of the criticisms he addresses to his predecessors - Platonists and materialists - is made. On the one hand, Aristotle exposes thoses theories for not being able to explain certain natural facts, such as the constancy of reproduction; on the other, he finds the origin of this deficiency in the emphasis these philosophers give to one cause alone (...) (be it material or formal). A solution to these problems, Aristotle argues, can only be reached if we seriously consider the four causes: material, formal, efficient and final. (shrink)

Meteorology IV.12, the final chapter of Aristotle’s “chemical” treatise, is a major text for the traditional view that Aristotle believed in universal teleology, the idea that everything in the cosmos—including the elements, earth, water, air, and fire—is what it is because of the goal or good it serves. But in the context of the rest of Meteorology IV, a different picture emerges. Meteorology IV.1–11 analyze the dispositional properties of material compounds (malleability, elasticity, etc.), examine the behavior of stuffs when heated (...) and cooled, and provide the resources to classify kinds in terms of their material composition and dispositional properties. Meteorology IV.12 places itself within that larger investigation but takes a different approach, examining those same materials from the perspective of their functions in bodies of greater complexity (e.g., the function of flesh in an organism). I argue that the teleological account of, say, the elements is limited to their function in the composition of complex kinds, such as living organisms, and that outside such a complex the elements behave as they do, not for the sake of some good they serve but “of necessity,” according to their material natures and interactions with other materials.

This paper presents a discussion about how the necessity and teleology are present in the theory of nature in Empedocles and Aristotle. For this task we go through the fragments relate to the thought of Empedocles in the Poem From Nature as a central reference to the work The presocratic philosophers of Kirk and Raven, and the work Physics I and II of Aristotle.

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)

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

I will argue that Aristotle’s fourfold division of four causes naturally arises from a combination of two distinctions (a) between things and changes, and (b) between that which potentially is something and what it potentially is. Within this scheme, what is usually called the “efficient cause” is something that potentially is a certain natural change, and the “final cause” is, at least in a basic sense, what the efficient cause potentially is. I will further argue that the essences of things (...) and changes are not features or attributes of them, but paradigms that set the standards according to which these things and changes may be judged to be natural or typical. The “formal cause” of a natural thing will be shown to be its essence in this sense: it sets the standards of typicality that apply to instances of its kind. The final cause will be shown to set the standard of typicality for natural changes. When we understand Aristotle’s doctrine of the four causes in this way, it becomes clear on what basis he could convincingly argue that final causality is operative in the whole of nature. (shrink)

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.

In some influential histories of ancient philosophy, teleological explanation and mechanistic explanation are assumed to be directly opposed and mutually exclusive alternatives. I contend that this assumption is deeply flawed, and distorts our understanding both of teleological and mechanistic explanation, and of the history of mechanistic philosophy. To prove this point, I shall provide an overview of the first systematic treatise on mechanics, the short and neglected work Mechanical Problems, written either by Aristotle or by a very early member of (...) his school. I will argue that the work is thoroughly Aristotelian in methodology, and that taking it seriously can deepen our understanding of Aristotle’s discussion of animal and human self-motion in the Physics and On the Movement of Animals.

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

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?’.

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. (shrink)

O presente texto tem por simples objectivo o comentário sistemático ao capítulo 2 do Livro V da Metafísica de Aristóteles (1013a24-1014a25), onde o autor apresenta (o mais próximo de) uma sistematização sobre o chamado modelo das quatro causas. Teremos também no horizonte de análise o famoso capítulo 3 do Livro I do mesmo tratado, onde Aristóteles inicia a crítica à tradição precedente justamente à luz deste modelo de causalidade. O objectivo (tendencialmente filológico e talvez até demasiado 'escolástico') é apenas comentar (...) e esclarecer o texto original, cujas hesitantes formulações podem levantar alguns obstáculos de interpretação.

The diversity of interpretations of Aristotle’s treatment of chance and luck springs from an apparent contradiction between the claims that “chance events are for the sake of something” and that “chance events are not for the sake of their outcome.” Chance seems to entail the denial of an end. Yet Aristotle systematically refers it to what is for the sake of an end. This paper suggests that, in order to give an account of chance, a reference to “per accidens causes” (...) is not sufficient. Chance occurs as a parody of teleology; it is a“for-no-purpose” that looks like a purpose. The notion of “irony” is suggested as a way of accounting for a situation that keeps an ambiguity open. The fact that chance is thought of in relation to teleology does not mean that it is “reappropriated” by teleology. Rather,chance reveals a hiatus that betrays the limitation of a language concerned with substances to account for events. (shrink)

This article explores the main aspects of Aristotle’s scientific method in Meteorology IV. Dispositional properties such as solidifiability or combustibility play a dominant role in Meteor. IV (a) in virtue of their central place in the generic division of homoeomers, based on successive differentiation and multiple differentiae, and (b) in virtue of their role in revealing otherwise undetectable characteristics of uniform materials (composition and physical structure). While Aristotle often starts with accounts of ingredients and their ratio (e.g., solids that contain (...) a significant amount of water are liquefiable), the natural direction of his investigation is from observations regarding dispositional properties and their manifestation to accounts of composition and microstructure. Such passages tend to be easily syllogizable, a feature that—along with the criteria that shape his method of division—argues, I believe, for the compatibility of Meteor. IV with Aristotle’s theory of scientific inquiry. The concluding sections of my article deal more succinctly with reputable opinions and final causation in Meteor. IV.1–11 and with the relation between this treatise and Aristotle’s biological corpus. (shrink)

Réplica a Angioni, “Relações causais entre eventos na ciência aristotélica: uma discussão crítica de Ciência e Dialética em Aristóteles, de Oswaldo Porchat”.

Aristotle’s typical procedure is to identify four causes of natural changes. Intentional action, a natural change, has standardly been treated as an exception: most think that Aristotle has the standard causalist account, according to which an intentional action is a bodily movement efficiently caused by an attitude of the appropriate sort. I show that action is not an exception to Aristotle’s typical procedure: he has the resources to specify four causes of action, and thus to articulate a powerful theory of (...) action unlike any other on offer.
