Although Aristotle's contribution to biology has long been recognized, there are many philosophers and historians of science who still hold that he was the great delayer of natural science, calling him the man who held up the Scientific Revolution by two thousand years. They argue that Aristotle never considered the nature of matter as such or the changes that perceptible objects undergo simply as physical objects; he only thought about the many different, specific natures found in perceptible objects. Against this (...) view, this book argues that Aristotle offers a systematic account of matter, motion, and the basic causal powers found in all physical objects. It argues that Aristotle not only sees all perceptible objects as sharing certain basic physical properties, but he also holds that perceptible objects have these physical properties because they are ultimately made from physical matter of one kind or another. Finally, it argues that for Aristotle the basic properties of matter, including the basic properties of the material elements, cannot be understood teleologically. (shrink)

Much of the debate about Aristotle’s criticisms of Plato has focused on the separability of the Forms. Here the dispute has to do with the ontological status of the Forms, in particular Plato’s claim for their ontological priority in relation to perceptible objects. Aristotle, however, also disputes the explanatory and causal roles that Plato claims for the Forms. This second criticism is independent of the first; even if the problem of the ontological status of the Forms were resolved to Aristotle’s (...) satisfaction, this second criticism would still stand. The problem here is not that there is no room for Aristotle’s four causes in Plato’s ontology; on the contrary, antecedents for all four can be found in Plato’s works. The problem, instead, is that Plato’s Forms fail to meet the general requirements that Aristotle sets out for the material, efficient, formal, and final causes of perceptible objects. Hence, even if the Forms were immanent in perceptible objects, they would still explain nothing about them. (shrink)

Some commentators have argued that there is no room in Aristotle's natural science for simple, or unconditional, physical necessity, for the only necessity that governs all natural substances is hypothetical and teleological. Against this view I argue that, according to Aristotle, there are two types of unconditional physical necessity at work in the material elements, the one teleological, governing their natural motions, and the other non-teleological, governing their physical interaction. I argue as well that these two types of simple necessity (...) also govern everything made out of the elements, that is, all other natural substances and artifacts. (shrink)

This chapter considers Aristotle's requirements for perceptible objects qua movable, changeable, and perceptible, namely that they must be extended in three dimensions, movable in space, and capable of physical contact with other extended bodies.

In the context of Aristotle's metaphysics and natural philosophy, 'prime matter' refers to that material cause which is both the proximate material cause of the four sublunary elements and the ultimate material cause of all perishable substances. On the traditional view, prime matter is pure potentiality, without any determinate nature of its own. Against this view, I argue that prime matter must be physical, extended, and movable matter if it is to fulfil its role as the substratum persisting through the (...) generation and corruption of these elements and the individuating subject in which their defining properties are found.

Gregory Vlastos has argued that Aristotle and other commentators on the Phaedo have mistakenly interpreted Plato’s Forms to be efficient causes. While Vlastos is correct that the Forms by themselves are not efficient causes, because of his neo-Kantianism he has misunderstood the close connection between the Forms and the explanation of change, including teleological change. This paper explores the connection in Plato’s Phaedo between the Forms, the nature of change, and efficient causality, and argues that Aristotle’s remarks are not as (...) misplaced as Vlastos claims.

In his metaphysics and natural philosophy, Aristotle uses the concept of a material cause,i.e., that from which something can be made or generated. This paper argues that Aristotle also has a concept of matter in the sense of physical stuff. Aristotle develops this concept of matter in the course of investigating the material causes of perceptible substances. Because of the requirements for change, locomotion, and the physical interaction of material objects, Aristotle holds that all perceptible substances must be extended in (...) three dimensions, movable, and corporeal due to their material causes. Thus, perceptible substances are physical substances because they are made out of something physical. (shrink)

RÉSUMÉBeaucoup ont soutenu qu'il n'y a pas de place pour des expériences scientifiques dans les sciences naturelles d'Aristote : les expériences interviennent dans la nature, mais Aristote soutient que nous devons simplement observer la nature; si nous intervenions, le résultat serait quelque chose d'artificiel ou contraire à la nature. Contre cela, je soutiens qu'Aristote a non seulement effectué des expériences scientifiques, mais a également maintenu qu'il y a beaucoup de connaissances sur la nature qui peuvent être découvertes expérimentalement.

Aristotle uses two kinds of material cause in his analysis of biological organisms: compositional matter, which persists through their birth and death;and functional matter, which consists of the organs and functional parts out of which biological organisms are made while they are alive. These two kinds of material cause, it has been argued, have quite different explanatory roles: functional matter is required by biological organisms to perform their essential functions,but compositional matter contributes nothing necessary to them and is only responsible (...) for their accidental properties. Against this view, I argue that biological organisms are systematically dependent upon their compositional matter and the latter is responsible for many of their necessary attributes. (shrink)

In traditional and popular accounts, Zen Buddhism is depicted as a practice that rejects literary study and intellectualization in favor of a direct experience of enlightenment that is beyond words. Indeed, the Zen school has traditionally defined itself as a "separate transmission outside the teachings, not dependent on words and letters". Even when regarding the tradition's literary output, Zen literature is famous for its antinomian dialogues replete with outrageous antics, frequent non sequiturs, and crude, illiterate utterances that appear to validate (...) the perspective that Zen simply rejects logical thinking, rational discourse, literary cultivation, and any systematic means of study. While it is... (shrink)

According to a long interpretative tradition, Aristotle holds that the formal cause is the ultimate object of induction when investigating perceptible substances. For, the job of induction is to find the essential nature common to a set of individuals, and that nature is captured solely by their shared formal cause. Against this view, I argue that Aristotle understands perceptible individuals as irreducibly composite objects whose nature is constituted by both their formal and their material cause. As a result, when investigating (...) perceptible objects, the job of induction is to discover their composite, formal and material nature. The process by which universal claims about this composite nature are justified, I argue, is similar to what we now know as mathematical induction. In particular, such claims are grounded in a non-enumerative, but replicable process in which things are resolved into their simplest components. As a result, the observation of past uniformities has, at most, a heuristic function in scientific inquiry. (shrink)

Formal approaches that aim at representing human reasoning should be evaluated based on how humans actually reason. One way of doing so is to investigate whether psychological findings of human reasoning patterns are represented in the theoretical model. The computational logic approach discussed here is the so-called weak completion semantics which is based on the three-valued ᴌukasiewicz logic. We explain how this approach adequately models Byrne’s suppression task, a psychological study where the experimental results show that participants’ conclusions systematically (...) deviate from the classical logically correct answers. As weak completion semantics is a novel technique in the field of computational logic, it is important to examine how it corresponds to other already established non-monotonic approaches. For this purpose we investigate the relation of weak completion with respect to completion and three-valued stable model semantics. In particular, we show that well-founded semantics, a widely accepted approach in the field of non-monotonic reasoning, corresponds to weak completion semantics for a specific class of modified programs.

Seventeenth-century advancements in physical science are often presented as overthrowing the Aristotelian tradition; perhaps Aristotle's emphasis on formal and final causes left little room for a physical theory grounded in material and efficient causes. In Aristotle's Science of Matter and Motion, Christopher Byrne argues that Aristotle is not to blame, as he indeed possessed a unified theory of matter and motion. In contrast to traditional interpretations, which place an undue explanatory burden on formal and final causes, Byrne (...) argues that Aristotle's theory of the physical world is dependent on the features possessed by perceptible objects, qua perceptible, as well as non-teleological changes in matter.Byrne's...

Siegel and Byrne debate whether perceptual experiences present rich properties or exclusively thin properties.

This study provides a survey of phenomena that present themselves during moments of naturally occurring inner experience. In our previous studies using Descriptive Experience Sampling we have discovered five frequently occurring phenomena—inner speech, inner seeing, unsymbolized thinking, feelings, and sensory awareness. Here we quantify the relative frequency of these phenomena. We used DES to describe 10 randomly identified moments of inner experience from each of 30 participants selected from a stratified sample of college students. We found that each of the (...) five phenomena occurred in approximately one quarter of sampled moments, that the frequency of these phenomena varied widely across individuals, that there were no significant gender differences in the relative frequencies of these phenomena, and that higher frequencies of inner speech were associated with lower levels of psychological distress.

This study takes inquiry as the starting point for epistemological theorising. It uses this idea to develop new and systematic answers to some of the most fundamental questions in epistemology, including about the nature of core epistemic phenomena as well as their value and the extent to which we possess them.

Three arguments for the thesis that sex is socially constructed are examined and rejected. No such argument could succeed, because sex is not socially constructed.

The coherence objection to the doctrine of the Incarnation maintains that it is impossible for one individual to have both the attributes of God and the attributes of a human being. This article examines Thomas Aquinas’s answer to this objection. I challenge the dominant, mereological interpretation of Aquinas’s position and, in light of this challenge, develop and defend a new alternative interpretation of Aquinas’s response to this important objection to Christian doctrine.

Assertion is the central vehicle for the sharing of knowledge. Whether knowledge is shared successfully often depends on the quality of assertions: good assertions lead to successful knowledge sharing, while bad ones don't. In Sharing Knowledge, Christoph Kelp and Mona Simion investigate the relation between knowledge sharing and assertion, and develop an account of what it is to assert well. More specifically, they argue that the function of assertion is to share knowledge with others. It is this function that supports (...) a central norm of assertion according to which a good assertion is one that has the disposition to generate knowledge in others. The book uses this functionalist approach to motivate further norms of assertion on both the speaker and the hearer side and investigates ramifications of this view for other questions about assertion.

argument fails, and the purpose of this note is to bring out that failure. The view in question which Heck calls the Hybrid Vie~istinguishes between the meanings of names and the contents of beliefs which are expressible using names. According to the Hybrid View the meaning of a name is its referent: names do not have senses. Thus (a) "George Orwell wrote 1984" means the same as (b) "Eric Blair wrote 1984". However, the Hybrid View tells a different story about (...) the beliefs one expresses when one utters (a) or (b). The content of a belief expressed using a sentence that contains a name has more to it than just the referent of the name and whatever properties the sentence ascribes to the name's referent.

The ethics of autonomous cars and automated driving have been a subject of discussion in research for a number of years :28–58, 2016). As levels of automation progress, with partially automated driving already becoming standard in new cars from a number of manufacturers, the question of ethical and legal standards becomes virulent. For exam-ple, while automated and autonomous cars, being equipped with appropriate detection sensors, processors, and intelligent mapping material, have a chance of being much safer than human-driven cars in (...) many regards, situations will arise in which accidents cannot be completely avoided. Such situations will have to be dealt with when programming the software of these vehicles. In several instances, internationally, regulations have been passed, based on legal considerations of road safety, mostly. However, to date, there have been few, if any, cases of a broader ethics code for autonomous or automated driving preceding actual regulation and being based on a broadly composed ethics committee of independent experts. In July 2016, the German Federal Minister of Transport and Digital Infrastructure, Alexander Dobrindt, appointed a national ethics committee for automated and connected driving, which began its work in September 2016. In June 2017, this committee presented a code of ethics which was published in German and in English. It consists of 20 ethical guidelines. Having been a member of this committee, I will present the main ethical topics of these guidelines and the discussions that lay behind them. (shrink)

In this essay, I argue that a proper understanding of the historicity of love requires an appreciation of the irreplaceability of the beloved. I do this through a consideration of ideas that were first put forward by Robert Kraut in “Love De Re” (1986). I also evaluate Amelie Rorty's criticisms of Kraut's thesis in “The Historicity of Psychological Attitudes: Love is Not Love Which Alters Not When It Alteration Finds” (1986). I argue that Rorty fundamentally misunderstands Kraut's Kripkean analogy, and (...) I go on to criticize her claim that concern over the proper object of love should be best understood as a concern over constancy. This leads me to an elaboration of the distinct senses in which love can be seen as historical. I end with a further defense of the irreplaceability of the beloved and a discussion of the relevance of recent debates over the importance of personal identity for an adequate account of the historical dimension of love.

In lieu of an abstract, here is a brief excerpt of the content:A Humanist History of Mathematics?Regiomontanus's Padua Oration in ContextJames Steven ByrneIn the spring of 1464, the German astronomer, astrologer, and mathematician Johannes Müller (1436–76), known as Regiomontanus (a Latinization of the name of his hometown, Königsberg in Franconia), offered a course of lectures on the Arabic astronomer al-Farghani at the University of Padua. The only one of these to survive is his inaugural oration on the history and utility (...) of the mathematical arts.1 Regiomontanus tells his audience that the purpose of the oration is torelate first the origin of our arts, and among which nations they first began to be cultivated, in what way they were at last translated from various foreign tongues into Latin, which of our ancestors were famed in these disciplines, and to whom in our lifetimes recognition should be granted.2To this end, he offers a history of the quadrivial arts (arithmetic, geometry, music, and astronomy) and other important mathematical disciplines from [End Page 41] antiquity to his own time, praises their utility, and exhorts his audience to revive the languishing study of mathematics at Padua. Astrology, a discipline with which Regiomontanus himself was closely associated, is singled out for particular praise.Traditionally, Regiomontanus's Padua oration has been seen through the lens of its rather obvious humanism. In particular, the Padua oration has come to be understood as the rhetorical embodiment of the fifteenth-and-sixteenth-century revival of ancient (Greek) mathematics. Just as this revival is inextricable from the rise of humanism, so Regiomontanus has come to be seen as an exemplar of humanist mathematics.3 It is the aim of this paper to examine the Padua oration in the context both of contemporary humanist rhetoric and of Regiomontanus's own intellectual background in order to argue that, while the oration is stylistically consistent with humanist norms, the vision of mathematics presented in it is also deeply grounded in the university mathematical curriculum and in Regiomontanus's own reading of mathematical texts.Regiomontanus was educated primarily at the University of Vienna (he was also briefly at the University of Leipzig), where he enrolled in 1450, completed his baccalaureate in 1452 and became a master in 1457.4 He remained at Vienna until 1461, when the death of his friend and teacher Georg Peurbach prompted him to travel to Italy with his patron, Cardinal Bessarion.5 In Regiomontanus's day Vienna was probably the most important of the German universities, rivaled only by Prague, whose prestige had declined after it was stripped of its theology faculty in the aftermath of the Hussite Wars.6 The curriculum at the University of Vienna was modeled [End Page 42] after that of Paris, and Parisian scholars played a major role both in its founding in 1365 and in its re-establishment (this time with a theology faculty) in 1384.7Most importantly for the purposes of this paper, the Viennese mathematical curriculum of Regiomontanus's day included all of the traditional authorities taught at Paris in the fourteenth century. For arithmetic and algebra, various "algorisms" (prose or poetry instructions for carrying out arithmetical operations that often also included a small amount of number theory) were the basic texts, supplemented in the fourteenth century by the Quadripartitum numerorum of Jean de Murs. Jordanus de Nemorare's De numeris datis and al-Khwarizmi's Algebra were common sources for those engaged in more advanced studies (i.e., they were not normally the subject of ordinary lectures, but were readily available to interested students, and would perhaps have been the subject of occasional extraordinary lectures). Euclid's Elements, supplemented by the commentaries of Pappus and Campanus, was the central text for geometry, and a number of medieval texts on practical and speculative geometry were in circulation as well. For astronomy, the Sphere of Sacrobosco and the Theorica planetarum were the most commonly used teaching texts, sometimes supplemented by al-Farghani's Elements of Astronomy (the subject of Regiomontanus's Padua lectures). Advanced students could read numerous more specific treatises by Arabic and Latin authors. For optics, the Perspectiva communis of John Peckham was the most common basic text, with texts... (shrink)

This handbook article gives a critical overview of recent discussions of epistemic authority. It favors an account that brings into balance the dictates of rational deference with the ideals of intellectual self-governance. A plausible starting point is the conjecture that neither should rational deference to authorities collapse into total epistemic submission, nor the ideal of mature intellectual self-governance be conflated with (illusions of) epistemic autarky.

The human body has come to be seen as forever susceptible to both external and internal hazards, which in many circumstances require immediate, heroic, and expensive intervention. In response to this, there has been a shift from a treatment‐based healthcare model to one of prevention wherein nurses play an integral role by identifying and assessing risks for individuals, communities, and populations. This paper uses Deborah Lupton’s outline of the spectrum of risk and applies the theoretical works of Foucault and Plato (...) to demonstrate the means by which nurses maintain social order by identifying and counselling risk takers. It also utilizes the work of Deleuze and Guattari to illustrate how Plato’s framework for creating social order through the creation of the good citizen can be viewed as a micro‐fascist system, which has been adopted wholeheartedly by preventative health professionals. The goal of this paper is to present an alternate understanding of risk to provide nurses and other healthcare professionals with a non‐traditional appreciation of certain aspects of their practice as researchers and clinicians.
