The last half-century has witnessed a resurgence of interest in Aristotle's Topics and his theory of dialectic—culminating in J. D. G. Evan's book about Aristotle's concept of dialectic; the decision to devote the entire Third Symposium Aristotelicum to the Topics; and the appearance of a small but steady stream of articles, several of which are now conveniently bound together in the first volume of Articles on Aristotle, edited by Barnes, Schofield, and Sorabji. These studies provide two somewhat incompatible views of (...) Aristotle's dialectic. On the one hand, it is argued that dialectic—as a method parallel but inferior to demonstration—was superseded by the discovery of the scientific method, or that dialectic—as a method of discussing first principles and of eliciting assent during debate—is at best a propadeutic to philosophic inquiry. These assessments are a consequence of the view that, what ever its strengths, dialectic can never transcend the level of opinion with which it begins, so as to achieve knowledge or certainty. At the other side of the spectrum are those who maintain that in addition t o having nonphilosophic uses, for Aristotle dialectical inquiry is often an integral part of philosophic investigation and, on occasion, its most important part. To some, dialectic's role in philosophic investigation is limited to the verification of definitions already discovered and to bringing an investigator to the threshold of discovering first principles, to others, dialectic's last stage comprises part of the philosophic discovery itself.

In this paper, we provide a detailed critical review of current approaches to ecthesis in Aristotle’s Prior Analytics, with a view to motivate a new approach, which builds upon previous work by Marion & Rückert (2016) on the dictum de omni. This approach sets Aristotle’s work within the context of dialectic and uses Lorenzen’s dialogical logic, hereby reframed with use of Martin-Löf's constructive type theory as ‘immanent reasoning’. We then provide rules of syllogistic for the latter, and provide proofs of (...) e-conversion, Darapti and Bocardo and e-subalternation, while showing how close to Aristotle’s text these proofs remain.

Although the theory of the assertoric syllogism was Aristotle's great invention, one which dominated logical theory for the succeeding two millenia, accounts of the syllogism evolved and changed over that time. Indeed, in the twentieth century, doctrines were attributed to Aristotle which lost sight of what Aristotle intended. One of these mistaken doctrines was the very form of the syllogism: that a syllogism consists of three propositions containing three terms arranged in four figures. Yet another was that a syllogism is (...) a conditional proposition deduced from a set of axioms. There is even unclarity about what the basis of syllogistic validity consists in. Returning to Aristotle's text, and reading it in the light of commentary from late antiquity and the middle ages, we find a coherent and precise theory which shows all these claims to be based on a misunderstanding and misreading.

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

In a chapter of The Methods of Ethics entitled “Ultimate Good”, Henry Sidgwick defends hedonism, the theory that pleasure and only pleasure is intrinsically good, that is, good in itself and apart from its consequences. First, however, he argues against the theory that virtue is intrinsically good. Sidgwick considers both a strong version of this theory — that virtue is the only intrinsic good — and a weaker version — that it is one intrinsic good among others. He tries to (...) show that neither version is or can be true. Against the strong version of the theory, Sidgwick argues as follows. Virtue is a disposition to act rightly, and right action is identified by the good it promotes. But this means that treating virtue as the only intrinsic good involves a “logical circle”: virtue is a disposition to promote what is good, where what is good is itself just a disposition to promote what is good. Virtue turns out to be a disposition to promote virtue. As Hastings Rashdall notes in a commentary on Sidgwick, one can accept many of this argument's premises yet reject its conclusion. One can agree that right action is identified by its consequences but still hold that virtue is the only intrinsic good. One can do this if one denies that the relevant consequences are good. This is the Stoic view: certain states are “preferred”, and thus supply the criterion of right action, but are not themselves intrinsically good. (shrink)

In this paper I shall attempt to locate and articulate Aristotle's answer to a foundational question in the theory of action - viz., 'what is the proximate (efficient) cause of action?' This task is certainly of historical importance, since one cannot hope to understand Aristotle's interesting and influential theory of action without understanding his views on the proximate efficient cause of action. But the present project is not, I should think, of historical interest alone; for it has recently been argued (...) by a leading figure in the study of action, Myles Brand, that What [proximately] initiates action?' is the fundamental question in action theory, 1 and we shall see that Aristotle has the makings of a very plausible answer.

Interpretations of Aristotle's account of the relation between body and soul have been widely divergent. At one extreme, Thomas Slakey has said that in theDe Anima‘Aristotle tries to explain perception simply as an event in the sense-organs’. Wallace Matson has generalized the point. Of the Greeks in general he says, ‘Mind–body identity was taken for granted.… Indeed, in the whole classical corpus there exists no denial of the view that sensing is a bodily process throughout’. At the opposite extreme, Friedrich (...) Solmsen has said of Aristotle's theory, ‘it is doubtful whether the movement or the actualization occurring when the eye sees or the ear hears has any physical or physiological aspect.’ Similarly, Jonathan Barnes has described Aristotle as leaning hesitantly towards the view that desire and thought are wholly non-physical. But on the emotions and sense-perception, Barnes takes an intermediate position. Aristotle treats these, he says, as including physical and non-physical components. Other writers too have sought a position somewhere in the middle. Thus G. R. T. Ross concedes that we find in Aristotle ‘what looks like the crudest materialism’. It appears that objects produce changes in an organism, ‘and the reception of these changes in the sense organisperception’. But, he maintains, this gives us only half the picture. The complete theory ‘may in a way be designated as a doctrine of psychophysical parallelism’. W. D. Ross also seeks a middle position. He thinks that Aristotle sometimes brings out ‘the distinctively mental, non-corporeal nature of the act [of sensation].… But Aristotle cannot be said to hold successfully to the notion of sensation as a purely mental activity having nothing in common with anything physical. He is still under the influence of earlier materialism’. (shrink)

Philosophie grecqueest un ouvrage d'histoire de la philosophie du Vlesiècle av. J.-C. au XVesiècle byzantin et qui vient s'ajouter aux nombreuses histoires de la philosophie ancienne que nous a données l'historiographie française du xxesiècle. Le rythme de ces publications, même limitées à la tradition française, demeure impressionnant. En effet, une recherche rapide nous indiquerait facilement un rythme de publication d'environ une histoire de la philosophie ancienne tous les trois ans au cours de ce siècle. Une recherche plus poussée augmenterait sans (...) doute cette moyenne. Un esprit malin et tant soit peu insolent pourrait soutenir quePhilosophie grecqueest un ouvrage de trop sur les rayons déjà amplement garnis de nos bibliothèques et poserait la question fondamentale de la pertinence d'une nouvelle histoire de la philosophie ancienne en cette fin de siècle.

Prior Analytics by the Greek philosopher Aristotle and Laws of Thought by the English mathematician George Boole are the two most important surviving original logical works from before the advent of modern logic. This article has a single goal: to compare Aristotle's system with the system that Boole constructed over twenty-two centuries later intending to extend and perfect what Aristotle had started. This comparison merits an article itself. Accordingly, this article does not discuss many other historically and philosophically important aspects (...) of Boole's book, e.g. his confused attempt to apply differential calculus to logic, his misguided effort to make his system of ‘class logic’ serve as a kind of ‘truth-functional logic’, his now almost forgotten foray into probability theory, or his blindness to the fact that a truth-functional combination of equations that follows from a given truth-functional combination of equations need not follow truth-functionally. One of the main conclusions is that Boole's contribution widened logic and changed its nature to such an extent that he fully deserves to share with Aristotle the status of being a founding figure in logic. By setting forth in clear and systematic fashion the basic methods for establishing validity and for establishing invalidity, Aristotle became the founder of logic as formal epistemology. By making the first unmistakable steps toward opening logic to the study of ‘laws of thought’—tautologies and laws such as excluded middle and non-contradiction—Boole became the founder of logic as formal ontology.… using mathematical methods … has led to more knowledge about logic in one century than had been obtained from the death of Aristotle up to … when Boole's masterpiece was published.Paul Rosenbloom 1950.

The first book-length philosophical study on the Presocratic influences in Plotinus’ Enneads.

In recent years, Aristotle's treatment of the imagination has become the subject of renewed interest. A pioneering paper by Malcolm Schofield argued that, far from being the rag-bag of widely separate and more or less unrelated concerns that it had previously been generally taken to be, phantasia was, for Aristotle, a ‘loose-knit family concept’ covering all aspects of what Schofield labelled ‘non-paradigmatic sensory experience’. With that conclusion I am more or less in agreement, although only on the condition that ‘sensory’ (...) be given a suitably broad interpretation. My purpose in this paper is to tease out, in a necessarily limited and circumscribed manner, the implications of a proper understanding of Aristotle's developed concept of deliberative imagination, phantasia bouleutikê, for his moral theory and his account of rational action, and to indicate ways in which this is related to his accounts of mental imaging in the rest of the Parva Naturalia.

I examine the ancient and perennial notion of the elements (stoicheia) and its relation to an idea of place proper (topos) and natural place (topos oikeios) in Aristotle's work. Through an exploration of his accounts, I argue that Aristotle develops a robust theory of place that is relevant to current environmental and geographical thought. In the process, he provides a domestic household and home for earth, air, fire and water that offers a supplement or an alternative to more abstract and (...) controversial uses of a conception of 'nature' (physis). I identify and elaborate upon environmental aspects of place-based and elemental philosophy. (shrink)

En el artículo se examinan los dos intentos de Aristóteles por explicar el fenómeno de las acciones voluntarias e involuntarias: Ética Eudemia (EE) II 6-9 y Ética Nicomaquea (EN) III 1. Entre ambos tratamientos hay muchas coincidencias, pero también diferencias sustantivas, tanto en la caracterización de las acciones involuntarias como en la estrategia argumentativa general y la definición de lo voluntario. El artículo procura dar cuenta de dichas diferencias de contenido en función de la estrategia metodológica general por la que (...) opta Aristóteles en uno y otro caso. The article examines Aristotle's two attempts to explain the phenomena of voluntary and involuntary actions: Eudemian Ethics (EE) II 6-9 and Nicomachean Ethics (EN) III 1. Though there are notorious coincidences, there are also substantial differences between them in the characterization of involuntary actions, in the general argumentative strategy, and in the definition of voluntary actions. The paper endeavors to account for these material differences on the basis of the general methodological strategy used by Aristotle in each case. (shrink)

Aristotle's explanation of the “active intellect” inDe AnimaIII, 5 constitutes a problem for us simply because we have to take this philosopher so seriously. If he were a writer given to poetic lapses or mythical adornments to his work we could consider dismissing the whole chapter as unessential. However, we know that Aristotle does not write unessential chapters, and that he is invariably engaged in an attempt to explain his subject fully and systematically, neither adding to it nor leaving anything (...) out.TheDe Anima, for example, is an attempt to describe the characteristics of living things, in an ascending order from the basic functions of vegetables to the most abstract thinking by human beings. The activities of nutrition, sensation, common sense, imagination, and movement are presented in Book II and in the early part of Book III. (shrink)

Aristotle's treatment of trade in the Politics book one is usually regarded as especially hostile, and this is put down to snobbery and political prejudice on his part. The Greeks often regarded trade as a degrading thing for a free man to engage in, and it would be surprising if Aristotle's view of trade were entirely unconnected with this Greek sensibility. But there should be something more definite than a loose general affinity if a charge of prejudice is to be (...) taken seriously. A balance of hostile judgements over argued cases to back them up would be some sort of evidence for prejudice, and prima facie evidence against would be anything like a theory from which the hostile judgements followed as conclusions. Theories can be concocted to give the required conclusions, of course, and then we must try to decide how serious the theory is. It comes to this: is there so little in the reasons Aristotle gives for his condemnation of trade that they may be convincingly explained away and belittled as no more than expressions of attitudes?

This paper examines H.A. Prichard's defense of the view that moral duty is underivative, as reflected in his argument that it is a mistake to ask “Why ought I to do what I morally ought?”, because the only possible answer is “Because you morally ought to.” This view was shared by other philosophers of Prichard's period, from Henry Sidgwick through A.C. Ewing, but Prichard stated it most forcefully and defended it best. The paper distinguishes three stages in Prichard's argument: one (...) appealing to his conceptual minimalism, one an epistemological argument that parallels Moore's response to skepticism about the external world, and one arguing that attempts to justify moral duties on non-moral grounds distort the phenomena by giving those duties the wrong explanation or ground. The paper concludes by considering Prichard's critique of ancient ethics and in particular the ethics of Aristotle. The paper is broadly sympathetic to Prichard's position and arguments; its aim is partly to make a case for him as a central figure in the history of ethics. (shrink)

Rawls scholarship has not paid much attention to Rawls's early methodological writings so far, pretty much focusing on thereflective equilibrium(RE) which he is understood to have adopted inA Theory of Justice. Nelson Goodman's coherence-theoretical formulations concerning the justification of inductive logic inFact, Fiction and Forecasthave been suggested as the source of the RE. Following Rawls's methodological development in his early works, we shall challenge both these views. Our analysis reveals that the basic elements of RE can be located in his (...) ‘Two Concepts of Rules’ essay. We shall further show that the origins of RE go all the way back to Aristotle's methods of ethics, as RE accords with the methodology entitledsaving the appearances(SA) in recent Aristotle scholarship.
