Aristotle: Philosophy of Science

Physics IV.10 (217b30–218a30) is pivotal in Aristotle’s discussion of time, preceding his own account from IV.11 onward. Aristotle presents three puzzles about the existence of time with reference to the “Now”. Modern interpretations often view this section as an aporetic prelude with Aristotle’s failure to provide explicit solutions. This paper examines Simplicius’ alternative interpretation, which draws upon the theory of proof and the syllogistic model from the Posterior Analytics. Simplicius contends that the arguments’ failure lies in their inability to fit (...) within the suitable syllogistic framework to establish a demonstrable definition of time, not in their aporetic nature. Every science has to prove the relation between (i) establishing whether X exists and (ii) showing what X is by establishing what the cause of X is. In evaluating Simplicius’ interpretation, this paper addresses two key aspects of the exegesis of IV.10: firstly, Simplicius can show why the “Now” is not part of the definition of time, and secondly, the ancient commentator underscores the close connection between the arguments in Physics IV.10 and the broader context of Aristotle’s discussion of time. Modern interpreters fail to address both of these issues. (shrink)

A comprehensive history of how induction has been conceived, from Socrates to Karl Popper.

The subject of this essay is propria and their relation to essence. Propria, roughly characterized, are those real properties of a thing which are natural but nonessential to it, and which are said to “flow from” the thing’s essence, where this “flows from” relation is understood to designate a kind of explanatory relation. For example, it is said that Socrates’s risibility flows from his essential humanity; and it is said that salt’s solubility in water flows from the essential natures of (...) both salt and water. The question I raise and attempt to answer in this essay is: In what sense do propria “flow from” essences? What kind of explanatory relation is this exactly? Some suggest that it is a relation of logical consequence ; others, of grounding ; and still others, of formal causation. In this essay, I reintroduce and defend a view suggested by the late scholastic Spanish philosopher and theologian Francisco Suárez, who in 1597 wrote that effluence is best understood as a very special kind of efficient causation, which we can call the relation of emanation. The thesis of this essay, then, is that propria emanate from essences. Along the way, this paper offers a new taxonomy of types of propria; it explains the significance of propria for the metaphysics and epistemology of essences; it discusses at length varieties of efficient causation ; and then it offers an extensive abductive argument in favor of Suárez’s account, whereby the former accounts of effluence are critiqued, each in turn, and Suárez’s view is motivated and ultimately shown to be superior to its competitors.

In DA I.2–5, Aristotle offers a series of critical discussions of earlier Greek definitions of the soul. The status of these discussions and the role they play in the justification of Aristotle’s theory of soul in DA II–III is controversial. In contrast to a common view, I argue that these discussions are not dialectical but philosophical. I also contend that Aristotle does not consider earlier philosophical definitions of soul to be endoxa, but rather contradoxa – beliefs about which the many (...) and the wise disagree among themselves. Through an analysis of Plato’s and Empedocles’s definitions of soul, I show that these definitions are nevertheless treated by Aristotle as potential scientific principles for explaining two of the soul’s per se attributes: causing motion and cognition in animate bodies. The main role of the critical discussions in DA I.2–5 is to show that all such earlier definitions of soul fail this explanatory task. Nevertheless, I show that these chapters are not wholly aporetic. Aristotle makes progress by solving two scientific puzzles within them: whether the soul has spatial parts, and whether ‘soul’ refers to a uniform entity across biological species. (shrink)

Aristotle (384-322 B.C), a well know Greek philosopher, physician, scientist and politician. A variety of identifying researches have been written on him. It is therefore a considerable pride for the researcher to write something about him when even mentioning his name and his father's name is a point of prestige in the Greek Language. His name means the preferable sublimity whereas Nicomachus (his father's name) means the definable negotiator. His father's and mother's origin belongs to Asclepiade, the favorite origin in (...) Greek. Points of view regarding this figure are controversial some praise him and consider him the peak of philosophical thinker which makes humanity in general owe this genius thinker a great deal. Others believe that the effect of his thought on humanity is the reason behind the non-progress of science. Whatever ones opinion is, his thoughts have a wonderful force in stimulating and positively affecting the people's thinking. His philosophy is the greatest philosophy which the world has ever witnessed or which may ever witness., if it couldn’t solve some of the problems of philosophy, it at least, makes the world more rational than before. He is the founder of the philosophical language in describing a large number of philosophical terms which are still in use nowadays. Moreover his books and platonic dialogues are considered encyclopedias in providing a basis for philosophy even before Socrates. For theses among other reasons, I am choosing Aristotle as a subject for research and concentrating on natural philosophy. The critical side deals with the criticism of natural philosophers. In order to fully understand Aristotle, we should understand his predecessors. Their virtue is undeniable. Without them, Aristotle's and Plato's genius would never be in this ideal shape. In addition to that, they are philosophers and scientists who mixes between science, philosophy, morality and politics in a complementary form. They are a source of illumination to the human thinking in general. Without them humanity could never have got rid of mythology. This is the code of life, for many generations should pass before the rare genius could attain a prominent idea. When Tales formulates the philosophical question, where does the world come from? This is a decisive moment in human thinking similar to the coming moments, the one Parmenides, and Protagoras statement: man is the norm for all things. Pre-Socrates philosophers are all considered glowing points in drawing Aristotle's philosophy. Thus my book is entitles (Aristotle's criticism of Pre-Socratic Natural Philosophy) which means the concentration on the critical operation through which the natural side of the previous philosophers appears. The nature of the title forces me to deal with Aristotle's ideas from every point of view. Thus the book proceeds according to structure and criticism and the construction of Aristotle's philosophy. Because the title is comprehensive and limited simultaneously, I have chosen the critical subjects in the lights of the natural philosophy. I have divided the book into four chapters with fourteen sections in addition to the implemented parts included in every section purporting to cover every part of criticism looking for comprehensiveness. I have found it obligatory to mention something about Aristotle's view in criticism, in addition to a precise delimitation of nature and its subjects. This is the subject of the first chapter. The second chapter deals with the principles of natural body, i.e., the principles dealt with pre-Aristotle philosophy and then these three principles (Hyle, form ,and Non-being). After delaminating these sides, it is possible to deal with the details (Movement, Place, Time, Vacuum and Infinite) which are natural concepts for the third chapter. As a complementation to the natural sides, the chapter four deals with two topics , Universal and corruption, and theory of elements. This book, in my own opinion, is comprehensive to the majority of natural philosophers and it focuses on the argument of Aristotle's criticism to the views of natural philosophers before Socrates together with the discussion of the Aristotelian alternative from these points of view. Aristotle sometimes tends to praise the previous philosophers. This does not mean the non-conformity between what he wants to say and what they described. When he, for example, says that the previous philosophers realized the material defect in Thales idea that water is the origin of all things but Thales’ water is not like Aristotle's Hyle, it is completely different thing. Finally I have viewed the index of Arab Library, and was unable to trace a book which is especially oriented in this subject i.e. writings on Aristotle's criticism to natural philosophy before Socrates. Therefore I have been stimulated to write about a very new subject. This subject fills a gap in Arab studies. (shrink)

I explain what Aristotle means when, after puzzling about the matter of motion in incomplete animals (those without sight, smell, hearing), he suggests in De Anima III 11.433b31–434a5 that just as incomplete animals are moved indeterminately, desire and phantasia are present in those animals, but present indeterminately. I argue that self-motion and its directing faculties in incomplete animals differ in degree but not in kind from those of complete animals. I examine how an object of desire differs for an incomplete (...) animal. Using a comparison with Aristotle’s account of recollection, especially in unfavorable circumstances, I describe indeterminate self-motion. Finally, I discuss implications for our understanding of Aristotle’s accounts of the faculties of the soul and incomplete animals. (shrink)

I defend an interpretation of Aristotle’s Posterior Analytics Book I which distinguishes between two projects in different passages of that work: (i) to explain what a given science is and (ii) 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 I.2-9 and I.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 (as the syllogistic structure and coextension between terms) are unfoldings of the main project, i.e., to capture and present properly relevant causal-explanatory relations.

In a recent book, Substance and the Fundamentality of the Familiar, Ross Inman demonstrates the contemporary relevance of an Aristotelian approach to metaphysics and the philosophy of nature. Inman successfully applies the Aristotelian framework to a number of outstanding problems in metaphysics, philosophy of mind, and the philosophy of physics. Inman tackles some intriguing questions about the ontological status of proper parts, questions which constitute a central focus of ongoing debate and investigation.

There is little agreement about Aristotle’s philosophy of geometry, partly due to the textual evidence and partly part to disagreement over what constitutes a plausible view. I keep separate the questions ‘What is Aristotle’s philosophy of geometry?’ and ‘Is Aristotle right?’, and consider the textual evidence in the context of Greek geometrical practice, and show that, for Aristotle, plane geometry is about properties of certain sensible objects—specifically, dimensional continuity—and certain properties possessed by actual and potential compass-and-straightedge drawings qua quantitative and (...) continuous. For their part, the objects of stereometry are potential sensible three-dimensional figures qua quantitative and continuous. (shrink)

A lot of scholarly attention has been given to Aristotle’s account of how and why animals are capable of moving themselves. But no one has focused on the question, whether self-change is possible in plants on Aristotle’s account. I first give some context and explain why this topic is worth exploring. I then turn to Aristotle’s conditions for self-change given in Physics VIII.4, where he argues that the natural motion of the elements does not count as self-motion. I apply those (...) conditions to natural change in plants. Then I explore the reasons for and consequences of Aristotle’s argument that plants are incapable of sensation. I argue that for Aristotle plants cannot possess the directing faculties for self-change, namely, desire and phantasia. My goal is to show why growth, metabolism, and reproduction in plants would not count as self-change for Aristotle, despite many of these natural changes appearing as autonomous as the analogous changes in animals. This sheds light on how, for Aristotle, self-change differs from natural change. (shrink)

How many scientific demonstrations can a single phenomenon have? This paper argues that, according to Aristotle's theory of scientific knowledge as laid out in the Posterior Analytics, a single conclusion may be demonstrated via more than one explanatory middle term. I also argue that this model of multiple demonstration is put into practice in the biological writings. This paper thereby accomplishes two related goals: it clarifies certain relatively obscure passages of the Posterior Analytics and uses them to show how Aristotle (...) explains biological phenomena by reference to both final and material causes in the Parts of Animals. The first part of the paper explains the account of multiple demonstration present in the Posterior Analytics and distinguishes it from another kind of plural explanation rejected by Aristotle. The second part of the paper turns to the biological explanation in the Parts of Animals and shows how Aristotle's account of multiple demonstrations works in practice. The paper thus provides evidence for the claim that the ‘applied’ reasoning on display in the biological works is in harmony with the framework of the logical treatises, and thus may also shed light on questions of the unity of the Aristotelian corpus.

The main aim of my paper is to analyse Aristotle’s theory of language in the context of his Physics I.1 and via an analysis and an interpretation of this part of his Physics I try to show that (i) the study of human language (logos) significantly falls within the competence of Aristotle’s physics (i.e. natural philosophy), (ii) we can find the results of such (physical) inquiry in Aristotle’s zoological writings, stated in the forms of the first principles, causes and elements (...) of the human speech (logos) and (iii) the analogies (Phys. 184b13-14) made by Aristotle at the very end of the first chapter make better sense if we consider them in the broader context in which Aristotle recognizes language as a complex natural phenomenon we are born into and which has to be not only biologically, but also socially developed through our lives. Hence, I aim towards a more naturalistic reading of Aristotle’s views on language. (shrink)

This volume is the first in English to provide a full, systematic investigation into Aristotle's criticisms of earlier Greek theories of the soul from the perspective of his theory of scientific explanation. Some interpreters of the De Anima have seen Aristotle's criticisms of Presocratic, Platonic, and other views about the soul as unfair or dialectical, but Jason W. Carter argues that Aristotle's criticisms are in fact a justified attempt to test the adequacy of earlier theories in terms of the theory (...) of scientific knowledge he advances in the Posterior Analytics. Carter proposes a new interpretation of Aristotle's confrontations with earlier psychology, showing how his reception of other Greek philosophers shaped his own hylomorphic psychology and led him to adopt a novel dualist theory of the soul–body relation. His book will be important for students and scholars of Aristotle, ancient Greek psychology, and the history of the mind–body problem. (shrink)

Aristotle thinks that an account, alogos, of some sort is characteristic of craft,technē. Some scholars think that thelogoselement oftechnēis tagged onto experience as a theoretical element not directly engaged in successful production: I argue instead that thelogosgrounds the productive ability of craft, and also that is practically orientated in a way that distinguishes it from thelogosof theoretical science. Understanding thelogosof craft thus helps us explain how the craftsman differs both from the merely experienced practitioner and from the theoretical scientist.

_ Source: _Volume 63, Issue 2, pp 209 - 210 Aristotle says that it is in the nature of color to impart movement to transparent media. Typically this is interpreted as implying that these media must be transparent before color moves them. I argue that this is a mistake.

The paper is devoted to Aristotle's solution to Meno's paradox: a person cannot search for what he knows -- he knows it, and there is no need to search for such a thing -- nor for what he doesn't know -- since he doesn't know what he's searching for. The autor argues that Aristotle proposes solutions of this paradox for every stage of cognition, not only for exercising available scientific knowledge as regarded by most Aristotelian scholars. He puts more focus (...) on the importance of the distinction between 'progignoskein' (pre-existing cognition) and 'proepistasthai' (pre-existong knowledge) for Aristotle's solution of this paradox.

In his treatises Hero of Alexandria describes a range of devices for producing spectacles and generating wonder that have frequently been treated as marginal by historians of technology and science. In this paper I shall show that these devices and Hero’s emphasis on wonder-making are of central importance to the image that Hero presents of mechanics. Hero uses the concept of wonder to add an intellectual component to the utility of mechanics, to strengthen the epistemological claims of mechanics and to (...) relate mechanical expertise to divine cunning. He is thereby able to present mechanics as a form of knowledge which is epistemically on a par with philosophy, but which still maintains powerful practical consequence.Author Keywords: Hero of Alexandria; Wonder; Automata; Ancient Mechanics; Ancient Science.

The aim of this paper is to highlight the main features of the philosophy of science that are present in Aristotle’s Posterior Analytics. At the same time I attempt to point out some obscure proposals within his metascientific theory and to distinguish certain aspects in which the Aristotelian Model of science has become inapplicable nowadays.

The title of this book is a bit misleading. Although Malcolm Wilson does argue that Aristotle's theory of science is more unified than is usually thought to be the case, he also examines Aristotle's actual practice of science, particularly biology but also physics, ethics, politics, and the science of being qua being. Hence the central problem of this book is how in practice as well as in theory science is unified in the Aristotelian corpus.Wilson casts Aristotle's theory of science against (...) the Platonic search for universal definitions, which leads to a suppression of differences or ambiguities both among things and their definitions. “Aristotle,” Wilson observes, “sought to redress the imbalance apparent in the Academic prejudice towards the universal” . He does so by restricting the demonstrative syllogism, which forms the core of any scientific argument in two ways: terms must be related through their definitions, and predicates must attach to a subject directly and universally . Consequently, each science has a subject, what it is about, and “is the sum of the demonstrative syllogisms that concern the same subject” .But defining science in this way creates the problem that the sciences become too particularized, too isolated from one another. Here is Wilson's larger question: How can the project of science defined in the Posterior Analytics produce systematic knowledge in which the parts, themselves identified with the various sciences, are sufficiently integrated with one another to form a unified whole? Wilson claims that “abstraction” can serve as a “stepping‐stone” to identifying three ways in which the sciences can be seen as forming a unified whole . In the process of abstraction, a more abstract science, usually a brand of mathematics, “supplied principles and explanations for a fact or conclusion found in a distinct and subordinate natural science” . Understanding abstraction allows us to identify three forms of “semi‐abstraction”—analogy, focality, and cumulation—that allow Aristotle to connect the arguments and subjects of different sciences .A brief analysis of abstraction sets the stage for Wilson's larger project, a full treatment of analogy, particularly in the writings on biology , focality, first in the biological works and then in the Metaphysics —this portion of the analysis is followed by a brief consideration of, in the words of the section title, “Mixed Uses of Analogy and Focality” —and finally cumulation, in a discussion that deals mainly with the sciences of psychology and ethics . The book concludes with two short commentaries, one entitled “The Place of Theology in the Science of Being” , the other “Conclusion: Analogy, Focality, and Cumulation” .Wilson's treatment of the practice of science is sometimes surprisingly brief. The important problem of speed of change , for example, is analyzed in less than two pages . Further, Wilson, observing that the technique of establishing superordinate and subordinate science “and its place in the APo [have] been well studied by the secondary literature,” states that he will not “treat it in the same depth as the three other techniques” . Given its foundational role in his analysis, this technique requires a full examination here. But there is a more serious problem: subordination among sciences also appears in the Nicomachean Ethics 1.1, a text Wilson never mentions. Here subordination rests not on mathematical abstraction but on ends among things in the real world. Thus Wilson does not provide a foundation strong enough to support his argument. (shrink)

Michael T. Ferejohn presents a new analysis of Aristotle's theory of explanation and scientific knowledge, in the context of its Socratic roots. Ferejohn shows how Aristotle resolves the tension between his commitment to the formal-case model of explanation and his recognition of the role of efficient causes in explaining natural phenomena.

Aristotle’s account of epistēmē is foundationalist. In contrast, the web of dialectical argumentation that constitutes justification for scientific principles is coherentist. Aristotle’s account of explanation is structurally parallel to the argument for a foundationalist account of justification. He accepts the first argument but his coherentist accounts of justification indicate that he would not accept the second. Where is the disanalogy? For Aristotle, the intelligibility of a demonstrative premise is the cause of the intelligibility of a demonstrated conclusion and causation is (...) asymmetric. Within the Posterior Analytics itself, Aristotle does not account for this, but elsewhere he develops the resources for doing so: the cause is what acts on a substrate to actualize a potential in that substrate, resulting in the effect. On the other hand, it may well happen that two propositions entail each other, in which case one may as well justify the one on the basis of the other as vice versa. (shrink)

The search for an agreement between Aristotle’s and Descartes’ philosophy was aimed at making Cartesian physics acceptable in the Dutch universities by showing its consistency with Aristotelian thought. Their agreement is defended by Johannes De Raey in the Clavis philosophiae naturalis (1654), where he interprets the Corpus Aristotelicum from a Cartesian standpoint. Those Aristotelian positions which are inconsistent with Descartes’ are treated as erroneous. The Scholastic positions, moreover, are considered as distant from the true Aristotelian philosophy rediscovered by Descartes.

Les "Seconds analytiques" contiennent les concepts et méthodes de la science aristotélicienne qui se retrouvent en acte dans les écrits biologistes. Cette étude s'intéresse aux passages sur la définition de l'âme, où Aristote use de deux procédés, la division et la démonstration. Elle met en évidence le caractère méthodique de l'argumentation et propose des solutions aux difficultés du texte.

In lieu of an abstract, here is a brief excerpt of the content:Notes and Discussions ARISTOTLE'S "DE MOTU ANIMALIUM" AND THE SEPARABILITY OF THE SCIENCES In contrast to Plato's vision of a unified science of reality and with a profound effect on subsequent natural science and philosophy, Aristotle urges in the Posterior Analytics and elsewhere that scientific knowledge is to be pursued in limited, separable domains, each with its own true and necessary first principles for the explanation of a discrete (...) range of phenomena, that is, accepted observations and beliefs, from which its investigations are launched (An. Pr. 46al7ff.; An. Post. 74b25, 76a26-3 o, 84b14-18, 88a31; Cael. 3o6a6ff.; Gen. An. 748a7ff.). In an early introduction to a course of lectures on the natural sciences, Aristotle also indicates the order in which those sciences ought to be presented (Mete. 338a2o-~9, 339a5-9; cf. Cael. 268al6, Part. An. 644b~2ff.). The plan is to start with a general discussion of change and motion, then progress to studies of specific natural phenomena, ending with the many species of plants and animals. In the theory of demonstration in Posterior Analytics 1, which is concerned with the organization, justification, and teaching of a finished science, Aristotle maintains that terms cannot ordinarily cross genera; for example, geometry cannot provide demonstrations of truths of arithmetic or aesthetics. Demonstration of a theorem of some one science by means of another can be accomplished when and only when the sciences are related as "subordinate " to "superior" (75b14-17), for example, as harmonics to arithmetic or optics to geometry. A superior science may supply the "reason" for a "fact" known to obtain in the subordinate science (78b34-79a6). Evidently at least part of what he has in mind is the relation between pure and applied sciences.' Aristotle's practice as well as a number of methodological remarks ' See ThomasAquinas,In Post. An. 50.1,15.131, 50.1.25,as wellasJ. Barnes'snoteson An. Post. 78b34,in Aristotle'sPosteriorAnalytics (Oxford:OxfordUniversityPress,1975).For relevant background see Ian Mueller,"Ascendingto Problems:Astronomyand Harmonicsin Republic VII," inJohn Anton,ed., Scienceand the Sciencesin Plato (Albany:StateUniversityof NewYork Press, 1979). [65] 66 HISTORY OF PHILOSOPHY suggest also that the strictures of the Posterior Analytics are not intended to prohibit the heuristic use of material from other disciplines in research (see e.g., Top. 1.14; Part An. 639b17ff., 641a6-14, 642alo-14, 645b15-2o; Ph. 192b8-34, 199a8-21, 199a33-b5). The requirements for science laid down here are very strict, and it is sometimes maintained that Aristotle violates them himself to some degree in other works, but it is not usually believed that he ever denies the separability of the sciences in general. Martha C. Nussbaum has recently presented a lively challenge to this concensus? She argues that Aristotle's late, little known work De Motu Animalium represents a radical but "deliberate and fruitful" rejection of his earlier philosophy of science as enunciated in the Organon and not seriously questioned in other, subsequent writings. Her claim is that in his mature thought about the sciences Aristotle arrives at a significantly "less departmental and more flexible picture of scientific study" (p. 113) and comes to hold that "no inquiry is genuinely separable from a whole group of interlocking studies, and no being can be extensively studied without an account of its placement in the whole of nature" (p. 164). Nussbaum's conclusion is probably not intended to be as Platonic as it may appear at first blush, for she seems actually to be speaking only of connections between sciences of different substances. There is no suggestion that the study of beauty or health or geometry, say, is on a par with the sciences of substances. Nor does she suggest that Aristotle wavers in his conviction that there are fundamental cleavages between the practical and theoretical sciences, which will make a full-blown science of ethics-politics look very different from the demonstrative science of meteorology, for example. Nevertheless, even if limited to the natural sciences of substances, her claim remains an important and interesting one. She holds, more specifically, that Aristotle departs from his earlier position as follows: (1) He recognizes that the biological study of various modes of local motion... (shrink)
