Aristotle: Chance

In Physics 2.4–6, Aristotle offers an account of things that happen “by luck” and “spontaneously”. Many of these things are what we might think of as “lucky breaks”: cases where things go well for us, even though we don’t expect them to. In Physics 2.5, Aristotle illustrates this idea with the case of a man who goes to the market for some reason unrelated to collecting a debt he is owed. While he is there, this man just so happens to (...) run into his debtor and get his money back—which is what he “wanted” all along. This case has a number of features that have proved puzzling. Most notably, Aristotle seems to think that while “it happened accidentally to him to come and to do this for the sake of getting the money”, nevertheless the man “did not come for the sake of this”—though he “would have”. What must such a proceeding be like to be described in these ways? Physics 2.4–6 makes several important moves towards answering this question. One of them—among the earliest and seemingly a foundational one—is the claim that “for the sake of something are as many things as could be done by thought and by nature”. The aim of this paper is to identify the role that this claim plays in Aristotle’s account of spontaneous proceedings. It defends two main claims. First, Aristotle’s suggestion that spontaneous proceedings could be done by nature and by thought is the product of a more general strategy. His approach is to sketch an intuitive pattern of explanation for proceedings that happen for the sake of something in the ordinary—non-spontaneous—way, and then to try to extend that model to the case of things that do so spontaneously, preserving as much of it as possible. Applying this strategy reveals that whereas nature and thought in fact function as efficient causes of ordinary proceedings that are for the sake of something, this cannot be the case in spontaneous ones. Instead, nature and thought could function as their causes. Second, I argue that Aristotle’s implementation of this strategy is rooted in his account of causation and especially Physics 2.3’s list of “modes” of causes. When he claims that spontaneous proceedings “could” be done by nature and by thought, he is saying that nature and thought are their efficient causes in capacity. In the practical case, spontaneous proceedings are caused by agents who have certain capacities, connected with their desires and abilities. In the right circumstances, these agents would actively exercise those capacities in acting for the sake of a given end. (shrink)

Aristotle contrasts standard animal generation with ‘spontaneous generation’, which happens when some material putrefies and gives rise to a new organism. This paper addresses two interrelated puzzles about spontaneous generation. First, is it of the same ‘fundamental kind’ of causal process as standard generation? Second, is it ‘spontaneous’, as understood in Physics 2.4–6: rare, accidentally caused, and among things that are for the sake of something? I argue that both puzzles turn on the same questions about the process types involved. (...) I show that the type putrefaction plays a more important role in spontaneous generation than has been recognized so far. Because putrefaction does not play this role in standard generation, the two processes are of different ‘fundamental’ kinds. Moreover, spontaneous generation happens rarely in that it is rare for processes of putrefaction to happen in such a way that they can also be described in terms of concoction. (shrink)

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

I offer a fresh interpretation of the dialectical strategy of Physics 2.8’s arguments that things in nature happen for the sake of something. Whereas many recent interpreters have concluded that these arguments inevitably beg the question against Aristotle’s opponents, I argue that they constitute a careful attempt to build common ground with an opponent who rejects Aristotle’s basic worldview. This common ground, first articulated in the famous Winter Rain Argument, takes the form of an intriguing pattern of reasoning: that natural (...) proceedings that happen in a given manner always or for the most part do not do so by chance.

This paper focuses on two short dubitationes on animal’s technical abilities, which Pietro Pomponazzi discussed in 1514 and in 1519 while teaching at the University of Bologna and commenting on Aristotle’s Physica, II, t. 80. A comparative analysis between the respective positions, expressed at a distance of five years, allows to retrace the change in Pomponazzi’s thoughts from the period immediately preceding the composition of De immortalitate animae to the writing of the De incantationibus and De fato.

This article offers an interpretation of Aristotle’s tenet that chance and accidental causes are indeterminate. According to one existing reading, the predicate ‘indeterminate’ is said of the effect of chance, meaning ‘causally indeterminate.’ Another reading claims instead that the predicate ‘indeterminate’ is said of the cause of a chance event, meaning something close to ‘potentially infinite in number.’ For my part, I contend that the predicate ‘indeterminate,’ when applied to Aristotle’s concept of accidental cause and to chance, is best understood (...) as a second-order predicate. More precisely, Aristotle uses ‘indeterminate’ to qualify a certain type of causal relation, rather than to indicate a quality of the causal power or of the effect. As a preparatory step in my argument, I contend that ‘accidental’ and ‘per se’ are also best understood as second-order predicates of ‘cause,’ and as a corollary of my main thesis I offer an interpretation of how chance involves an infinite number of possible causes.

В настоящата книга се изследва идеята за случайността през нейното историческо и концептуално развитие и са отделени пет основни и типични понятия. Анализът тръгва от класическите примери – Платон, Аристотел, Кант и Хегел – и стига до съвременния контекст на случайността, който е представен през теорията на вероятностите и теорията на сложността. Някои от изведените понятия са формализирани и имат по-логически, математически или пък информационен характер, а други са по-скоро физически или субектни, но всички те са представени в една обща (...) историческа типология. В нея се включва и парадигмата срещу случайността, която има теоретична, културна и дори органична природа. (shrink)

I discuss how Aristotle’s formulation of the problem of moral luck relates to his natural philosophy. I review well-known passages from Nicomachean Ethics I/X and Eudemian Ethics I/VII and Physics II, but in the main focus on EE VII 14 (= VIII 2). I argue that Aristotle’s position there (rejecting the elimination of luck, but reducing luck so far as possible to incidental natural and intelligent causes) is not only consistent with his treatment of luck in Physics II, but is (...) to be expected, given that the dialectical path of EE VII 14 runs exactly parallel to that of Physics II 4-6. Although Aristotle resolves some issues that he raises, he cannot avoid the problem of constitutive moral luck that, as Thomas Nagel puts it, pertains to ‘the kind of person you are, where this is not just a question of what you deliberately do, but of your inclinations, capacities, and temperament’. The problem for Aristotle follows not only from his ethical positions, but also directly from his more general physical and political principles and assumptions. Furthermore, the problem touches the very essence of Aristotle’s moral theory. (shrink)

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

An appreciation of the "more philosophical" aspects of ancient medical writings casts considerable light on Aristotle's concept of nature, and how he understands nature to differ from art, on the one hand, and spontaneity or luck, on the other. The account of nature, and its comparison with art and spontaneity in Physics II is developed with continual reference to the medical art. The notion of spontaneous remission of disease (without the aid of the medical art) was a controversial subject in (...) the medical literature, and Aristotle's aporia about the notion of spontaneous generation of natural things runs parallel to this controversy. Aristotle's account of spontaneous generation in the Metaphysics and in the Generation of Animals can also be profitably illuminated by looking at the comparison with medicine in detail. The result, hopefully, is a clearer and more consistent picture not only of Aristotle's concepts of nature, art, and spontaneity, but also of the influence of medical writings and concepts on his natural philosophy. Joel Mann has written a commentary on the essay. (shrink)

The book aims to offer a contribution to the historiographical and conceptual reconfiguration of the evolutionary revolution in the light of the centuries-old tenets of the Aristotelian biological tradition. Darwin’s breakthrough constitutes a thorough overturning of the fixist, essentialist and teleological framework created by Aristotle, a framework still dominant in the 17th Century world of Harvey and Ray, as well as Galileo, and then hegemonic until Linnaeus and Cuvier. This change is exemplified in the morphological analysis of useless parts, such (...) as the sightless eyes of moles, already discussed by Aristotle, and which Darwin used almost like a crowbar to unhinge the systematic recourse to final causes. This is an ancient teleological heritage present in various forms in the concept of natural selection, but by then confined within an eminently historical framework open to randomness. Un contributo alla riconfigurazione storiografica e concettuale della rivoluzione evoluzionistica alla luce della tenuta plurisecolare della tradizione biologica aristotelica. La svolta di Darwin si delinea quale puntuale rovesciamento dell'impianto fissista, essenzialista e teleologico coniato da Aristotele, ancora dominante nel Seicento di Harvey e di Ray, nonostante Galileo, e poi egemone fino a Linneo e Cuvier. Svolta esemplificata dall'analisi morfologica delle parti inutili, come gli occhi ciechi della talpa, tematizzate già da Aristotele, e che Darwin usò quale grimaldello per scardinare il ricorso sistematico alle cause finali. Antica eredità teleologica presente in varie forme nel concetto di selezione naturale, ma ormai calata entro una griglia eminentemente storica e aperta alla casualità. (shrink)

This work is the first monograph devoted to the interpretation of Aristotle’s theory of chance in Physics II 4-6 and its implications and projections in other treatises, including an original and comprehensive account of the Aristotelian conception of chance, of accidental causality in the realm of nature, and of accidental causality in the realm of human action. One of the main interpretative issues around Aristotle’s discussion of chance is its relation to the four causes and to teleology. In this sense, (...) it is particularly difficult to find the common features which fortune (tyche) and spontaneity (automaton) share. This work, offers such an interpretation of Aristotle’s general concept of chance (i.e. common to fortune and spontaneity), which shows clearly its relation with his theory of causality (Phys. II 3), with teleology, and with the application of this theory to the study of nature. It also shows how fortune and spontaneity can be interpreted consistently with this general characterization of chance, and how the specific differences between them can be accounted for paying attention to the different structures of causality in the realm of nature and in the realm of human action. Regarding the specific concept of spontaneity (automaton), a crux interpretum, the book offers one of the few independent discussions this issue in Aristotelian literature, and proposes a sub-classification in two kinds of spontaneity based on an analysis of Aristotle’s different examples and characterizations: ‘mixed spontaneity’ (which shares some features with fortune), and ‘pure spontaneity’ (which takes place strictly in the realm of nature). These different structures had not been recognized in specialized literature before. The problem of chance has projections into Aristotle’s natural philosophy, as well as into Aristotle’s theory of action and practical philosophy. This ample perspective of Aristotle’s work, and of the different explanatory models and ontological structures therein involved, constitutes an interesting groundwork for future developments in some or many of these realms of investigation.

In this paper I address some aspects of the discussion of Aristotle against materialism. I take as a starting point the inaugural sentence of Phys. 2.4, where Aristotle refers to the endoxon that there are things which are (einai), and things which become or are generated (gignesthai) by chance. In the first place, I show that Aristotle would have ascribed to the materialists (especially Empedocles) the opinion that things like animals and plants can be (and not only become) by chance. (...) I shall argue that, in fact, this thesis implies that it is not only the compound that is generated, but also the form or eidos of the living being. To this extent, I propose that there are strong reasons for Aristotle to reject that living beings may be by chance, and to circumscribe chance to that which becomes or is generated. In other words: chance can occur within processes of generation but has nothing to do with the causes and principles of those processes. Thus, this repositioning of chance within the sole field of what becomes is closely connected to the causal priority of the eidos in the processes of generation. (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)

This paper deals with Aristotle’s concept of chance, such as it is presented in Physics II 4-6. The central section of the article concentrates on an analysis of Aristotle’s definition of chance and its essential peculiarities: the fact of being an incidental (efficient) cause and the fact of existing in the domain of what is for the sake of an end. According to Rossi, both characteristics would correspond to a causal aspect (in an incidental sense) and to a non causal (...) aspect (or just apparently causal) of chance. Finally, the author also tries to show the structural connection between the aforementioned aspects, taking as a key point the thesis of coincidence among the formal, final, and efficient causes.

Este artículo trata el concepto aristotélico de azar, tal como se lo presenta en Física II 4-6. La sección central del artículo se concentra en el análisis de la definición aristotélica de azar y sus peculiaridades esenciales: el hecho de ser una causa accidental y el hecho de existir en el dominio de lo que es en vista de un fin. Según Rossi, ambas características corresponderían a un aspecto causal y a un aspecto no causal del azar. Por último, la (...) autora también trata de mostrar la conexión estructural entre los aspectos antes mencionados, tomando como hecho clave la tesis de la coincidencia entre las causas formal, final y eficiente.

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)

Tradução preliminar em pré-print. A Tradução definitiva é a de 2009.

Metaphysics Epsilon 2-3 and Nicomachean Ethics III 5 (1114b3-25) are often cited in favor of indeterminist interpretations of Aristotle. In Metaphysics Epsilon Aristotle denies that the coincidental has an aitia, and some (e.g., Sorabji) take this as a denial that coincidences have causes. In NE III 5 Aristotle says a person's actions and character must have their origin (archê) in the agent for him to be responsible for them. From this, some conclude that Aristotle thinks a person can be the (...) uncaused cause of his actions, (e.g., Hardie, Ross), or at least that there must be some sort of break in the causal nexus, so that the person's character cannot be traced back to an external origin (Furley). I argue that Metaphysics Epsilon does not show that Aristotle disbelieves in causal determinism, since he is dealing with issues of explanation in these passages, not causal necessitation. Metaphysics Epsilon 2-3 is not irrelevant to the controversy between compatibilist and incompatibilist interpretations of Aristotle, however. I will argue that a proper understanding of Metaphysics Epsilon's doctrine that the sumbebekos lacks an aitia sheds light on what Aristotle means in NE III 5 when he says that the voluntary must have an internal origin, and that it helps to show how one's action and character can have an 'internal origin' even if one's actions and character can be traced entirely to external causes. Finally, I will take this doctrine of the voluntary having an 'internal origin' and use it to illuminate Aristotle's discussion of the different types of excusing conditions in NE III 1. (shrink)
