Stewart Shapiro and Alan Weir have argued that a crucial part of the demonstration of Frege's Theorem (specifically, that Hume's Principle implies that there are infinitely many objects) fails if the Neo-logicist cannot assume the existence of the empty property, i.e., is restricted to so-called Aristotelian Logic. Nevertheless, even in the context of Aristotelian Logic, Hume's Principle implies much of the content of Peano Arithmetic. In addition, their results do not constitute an objection to Neo-logicism so much as (...) a clarification regarding the view of logic that the Neo-logicist must take. (shrink)

This book shows otherwise. John Martin rehabilitates Neoplatonism, founded by Plotinus and brought into Christianity by St. Augustine.

There is a wide range of realist but non-Platonist philosophies of mathematics—naturalist or Aristotelian realisms. Held by Aristotle and Mill, they played little part in twentieth century philosophy of mathematics but have been revived recently. They assimilate mathematics to the rest of science. They hold that mathematics is the science of X, where X is some observable feature of the (physical or other non-abstract) world. Choices for X include quantity, structure, pattern, complexity, relations. The article lays out and compares (...) these options, including their accounts of what X is, the examples supporting each theory, and the reasons for identifying the science of X with (most or all of) mathematics. Some comparison of the options is undertaken, but the main aim is to display the spectrum of viable alternatives to Platonism and nominalism. It is explained how these views answer Frege’s widely accepted argument that arithmetic cannot be about real features of the physical world, and arguments that such mathematical objects as large infinities and perfect geometrical figures cannot be physically realized.

An Aristotelian Philosophy of Mathematics breaks the impasse between Platonist and nominalist views of mathematics. Neither a study of abstract objects nor a mere language or logic, mathematics is a science of real aspects of the world as much as biology is. For the first time, a philosophy of mathematics puts applied mathematics at the centre. Quantitative aspects of the world such as ratios of heights, and structural ones such as symmetry and continuity, are parts of the physical world (...) and are objects of mathematics. Though some mathematical structures such as infinities may be too big to be realized in fact, all of them are capable of being realized. Informed by the author's background in both philosophy and mathematics, but keeping to simple examples, the book shows how infant perception of patterns is extended by visualization and proof to the vast edifice of modern pure and applied mathematical knowledge.

Questions concerning the epistemological status of computer science are, in this paper, answered from the point of view of the formal verification framework. State space reduction techniques adopted to simplify computational models in model checking are analysed in terms of Aristotelian abstractions and Galilean idealizations characterizing the inquiry of empirical systems. Methodological considerations drawn here are employed to argue in favour of the scientific understanding of computer science as a discipline. Specifically, reduced models gained by Dataion are acknowledged as (...) Aristotelian abstractions that include only data which are sufficient to examine the interested executions. The present study highlights how the need to maximize incompatible properties is at the basis of both Abstraction Refinement, the process of generating a cascade of computational models to achieve a balance between simplicity and informativeness, and the Multiple Model Idealization approach in biology. Finally, fairness constraints, imposed to computational models to allow fair behaviours only, are defined as ceteris paribus conditions under which temporal formulas, formalizing software requirements, acquire the status of law-like statements about the software systems executions.

Aristotelian, or non-Platonist, realism holds that mathematics is a science of the real world, just as much as biology or sociology are. Where biology studies living things and sociology studies human social relations, mathematics studies the quantitative or structural aspects of things, such as ratios, or patterns, or complexity, or numerosity, or symmetry. Let us start with an example, as Aristotelians always prefer, an example that introduces the essential themes of the Aristotelian view of mathematics. A typical mathematical (...) truth is that there are six different pairs in four objects: Figure 1. There are 6 different pairs in 4 objects The objects may be of any kind, physical, mental or abstract. The mathematical statement does not refer to any properties of the objects, but only to patterning of the parts in the complex of the four objects. If that seems to us less a solid truth about the real world than the causation of flu by viruses, that may be simply due to our blindness about relations, or tendency to regard them as somehow less real than things and properties. But relations (for example, relations of equality between parts of a structure) are as real as colours or causes. (shrink)

In the recent debate on future contingents and the nature of the future, authors such as G. A. Boyd, W. L. Craig, and E. Hess have made use of various logical notions, such as the Aristotelian relations of contradiction and contrariety, and the ‘open future square of opposition.’ My aim in this paper is not to enter into this philosophical debate itself, but rather to highlight, at a more abstract methodological level, the important role that Aristotelian diagrams can (...) play in organizing and clarifying the debate. After providing a brief survey of the specific ways in which Boyd and Hess make use of Aristotelian relations and diagrams in the debate on the nature of the future, I argue that the position of open theism is best represented by means of a hexagon of opposition. Next, I show that on the classical theist account, this hexagon of opposition ‘collapses’ into a single pair of contradictory statements. This collapse from a hexagon into a pair has several aspects, which can all be seen as different manifestations of a single underlying change. (shrink)

Abstract: This chapter examines the role of the virtuous agent in the acquisition of virtue. It rejects the view of the virtuous agent as a direct model for imitation and instead focuses on recent research on the importance of phronesis. Phronesis is understood as a type of moral ‘know how’ expertise that is supported by a variety of abilities, from emotional maturity, to self-reflection, to an empathic understanding of what moves others, to an ability to see beyond the surface and (...) understand the complexities of human behaviour. If we want to acquire virtue instead of focusing on the virtuous agent as such we should be trying to understand the abilities exemplified by his phronesis. As part of this project, I also consider philosophers who seek inspiration from the empirical sciences to shed light on how phronetic expertise is developed and what relevance this may have for moral education.

Two central accounts of human cognition emerge over the course of the Middle Ages: the theory of divine illumination and an Aristotelian theory centered on abstraction from sense data. Typically, these two accounts are seen as competing views of the origins of human knowledge; theories of divine illumination focus on God’s direct intervention in our epistemic lives, whereas Aristotelian theories generally claim that our knowledge derives primarily (or even entirely) from sense perception. In this paper, I address (...) an early attempt to reconcile these two accounts—namely, Robert Grosseteste’s commentary on Aristotle’s Posterior Analytics—and I argue that Grosseteste’s efforts to bring Aristotle’s account of human cognition into harmony with a theory of divine illumination proves both philosophically interesting and largely successful. Grosseteste’s claim that God does not directly illumine our intellects in this life opens his theory to the worry that Grosseteste leaves the divine out of his theory of divine illumination in the CPA. Steven Marrone, for example, holds that Grosseteste’s Aristotelian focus in this work causes him to abandon the theory of divine illumination he advocated in the earlier De veritate in favor of a modified theory of “human” illumination. I argue in contrast that Grosseteste does give God a role in human knowledge in the CPA—a role that allows human beings to remain largely responsible for the acquisition of knowledge while still requiring God’s illumination for actual cognition. In short, I conclude that, although human bodies interfere with God’s direct illumination of our intellects, God nevertheless plays a crucial ideogenic role in human cognition by illuminating the objects of our intellection and making them intelligible to us.

This book explores the reaction of tenth-century Arab philosopher Abu Nasr Alfarabi to the logical works of Aristotle. From numerous short treatises the author develops a systematic and comprehensive topical survey of Alfara bi's logical writings. The book is divided into two major parts: language as a tool of logic and logic as a tool with which to analyze language. The first five chapters deal with Alfarabi's analysis of the meanings of various terms as they are used in logic and (...) philosophy. Alfarabi refutes the Arab grammarians who claimed that Arab logicians were building a language within a language and shows that the philosophical meanings of terms are in fact their most original and essential meanings. The final chapter deals with Alfarabi's analysis of certain aspects of the Arabic language and demonstrates that Arabic, like any natural language, conforms to universal logical structures of which natural languages are only a concrete expression.

Aristotelian ethics is widely accepted by many scholars as a practical science. However, this study showed that it is not after all a practical science but a speculative or theoretical science. Having employed textual analysis on Aristotle’s Nicomachean Ethics, it was found out that eudaimonia the Highest Good/Chief Good which is the ultimate goal of Ethics is achieved not through action but through contemplation. Contemplation is the act not of the will but of intellect. Hence, the highest virtue or (...) excellence of man is the fulfilment of highest faculty which is reason in contemplation of the Chief Good. The Chief Good, which is characterized by Aristotle as final, complete, and Self-Sufficient End is not physical and concrete but rather incorporeal and abstract because such qualities cannot be found among corporeal entities. Thus, Aristotelian ethics is metaphysics; it is neither concrete nor practical. Moreover, happiness cannot be the Chief Good because happiness is merely an activity, a quality, and a disposition and an activity cannot be identified as end which is desired for its own sake. Therefore, the Chief Good must be a substance and this substance is the Final Cause/the Necessary Being which is the End of all ends and the Good of all goods.

We have modified Aristotelian syllogistic logic in for use in introductory philosophy courses. Although the scope of Aristotle's syllogistic is narrowed by our modifications, its pedagogical value is increased in one crucial way: in 4-6 hours of class time, students with no background in argumentation progress to the point where they can evaluate the structure of condensed and extended arguments. Because the mechanics of the program are readily grasped, it is possible to focus class time on important, abstract notions (...) such as validity, soundness, relevance, etc. If successfully implemented, the program encourages good habits for analysing, assessing and formulating arguments.

Although Burke, Bentham, Hegel and Marx do not often agree, all criticized certain ethical theories, in particular theories of rights, for being too abstract. The complaint is still popular. It was common in Existentialist and in Wittgensteinian writing that stressed the importance of cases and examples rather than principles for the moral life; it has been prominent in recent Hegelian and Aristotelian flavoured writing, which stresses the importance of the virtues; it is reiterated in discussions that stress the distinctiveness (...) and particularity of moral vicissitudes and query the importance of ethical theory. Recent critics of abstraction are opposed not only to theories of rights, and the Kantian notions with which these are linked, but also to consequentialist ethical theories. The two ethical theories that are most influential in the English-speaking world now both stand accused of being too abstract. (shrink)

A general theory of logical oppositions is proposed by abstracting these from the Aristotelian background of quantified sentences. Opposition is a relation that goes beyond incompatibility (not being true together), and a question-answer semantics is devised to investigate the features of oppositions and opposites within a functional calculus. Finally, several theoretical problems about its applicability are considered.

Biophilia is a concept that has been much utilized as a foundation for an environmental or “land” ethic. E.O. Wilson characterizes it as a genetic disposition that links human survival to valuing living systems. J. Baird Callicott argues that human sentiments are naturally directed to all living systems and beings and this sentiment has evolutionary value. This author contends that if biophilia is to be a viable foundation for such an ethic, it must be conceived more abstractly and broadly as (...) an interconnecting feature of biotic systems. The foundation for such a conception can be found in Aristotle’s ethics, wherein his discussion of friendship, philia, can provide a theory of interspecies obligation. Although Aristotle’s focus in the Nicomachean Ethics is human relations, he makes it clear that this sentiment can be felt towards other living beings. This paper develops a broader conception of philia that includes interspecies relationships and then reconceives the modern concept of biophilia as a form of interspecies philia. It goes on to argue, using Aristotle’s theory of obligation as reciprocity within friendship, that such a re-conception of biophilia might provide another approach to founding an environmental ethic on a theory of sentiment.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aristotelian Explorations by G. E. R. LloydRosamond Kent SpragueG. E. R. Lloyd. Aristotelian Explorations. Cambridge: Cambridge University Press, 1996. Pp. ix + 242. Cloth, $49.95.Although the essays in this richly rewarding book were given as lectures and seminars in a variety of places over a period of eight years, they possess a unity of theme that welds them into a satisfying whole. Furthermore, by the judicious (...) use of postscripts and additional notes, the author keeps us abreast of current discussion. [End Page 126]Lloyd’s chief concern is to compare Aristotle’s theory (notably as expressed in the Posterior Analytics) with his practice (especially in the zoology). The topic may be, as he admits in his 1990 Boston Colloquium lecture, “The Theories and Practices of Demonstration,” a “hoary old chestnut,” but his response to it is not; as is evident from the very title of his paper, he adopts a pluralistic approach to Aristotle’s methodology. Lloyd’s minute and extensive knowledge of the texts, as when he studies passages in the Topics in which what is there called apodeixis does not meet the conditions laid down in Posterior Analytics, makes his view compelling. Again, a careful study of Parts of Animals I, 1 issues in the caveat that “we had better be careful when talking about demonstration in the physical treatises, to examine what mode or manner of demonstration is in question” (33); it could be the method of deduction of antecedents, for instance, where we start with what will be rather than what is. In general, it needs to be considered not just whether a particular theory of demonstration is applied, but whether it is applicable.In a chapter entitled “The Relationship of Psychology to Zoology,” Lloyd discusses Aristotle’s theory of matter, particularly “the problem of reconciling what is true of earth, water, air, and fire haplōs... and what is true of them as the constituent elements of living uniform parts” (64). This difficulty has its repercussions for his form/matter distinction: the difference between the two is best illustrated by artefacts (as, I might add, is evident to those who attempt to teach it), but the unity of the sonolon by the cases in which the soul is form and the matter a living body of which the soul is the actuality.In this connection Lloyd makes reference to Aristotle’s “top-down theory of life” as being one quite definitely held by him (64, 99). I think that this is only partially the case. A passage such as De Anima 415a25ff. in which not only animals but plants are said, through reproduction, to aim at the eternal and divine, suggests that a “bottom-up” theory of life is equally important in his psychology, especially in view of his pervasive desire to stress the final cause. I think that Lloyd’s own principle of plurality in relation to context could well be applied here. The overall structure of the De Anima illustrates Aristotle’s use of both methods: bottom-up from nutrition through sensation to thought, but top-down from sight to touch. It is, of course, true that the De Anima is not concerned to address the question of how life emerges from not-life, but its discussion of living things quite definitely begins at the bottom of the scala naturae, with plants. Again, at History of Animals 588b4ff. (a passage crucial to Lloyd’s consideration of borderline cases in his chapter entitled “Fuzzy Natures?”), we find that Nature proceeds from the inanimate to the animate, and that first after the inanimate come plants. It also strikes me as being of interest that, when Aristotle discusses the difficult topic of growth in Generation and Corruption 321b16ff., he does so at the level of flesh and not of hands, from the bottom up, that is.Of other topics on which Lloyd has things to say, that of spontaneous generation is of particular interest. Here he points out that spontaneously generated creatures are of regular kinds; they have determinate material causes. As to whether Aristotle’s recognition of such cases has driven him “into admitting a principle that offers a glaring... (shrink)

The paper begins with an exposition of Aristotle’s own philosophy of mathematics. It is claimed that this is based on two postulates. The first is the embodiment postulate, which states that mathematical objects exist not in a separate world, but embodied in the material world. The second is that infinity is always potential and never actual. It is argued that Aristotle’s philosophy gave an adequate account of ancient Greek mathematics; but that his second postulate does not apply to modern mathematics, (...) which assumes the existence of the actual infinite. However, it is claimed that the embodiment postulate does still hold in contemporary mathematics, and this is argued in detail by considering the natural numbers and the sets of ZFC. (shrink)

The argument of this paper is that the Aristotelian analysis of justice and related concepts provides the best framework for understanding the structure and importance of justice in Dante’s Commedia. After giving a synopsis of the principle features of Aristotle’s account of justice in Book 5 of the Nicomachean Ethics, I consider a few scenes from the Inferno, the Purgatorio, and the Paradiso, showing how the punishments and rewards Dante describes are based on the Aristotelian analysis of justice. (...) Finally, I show that Dante, following Aristotle’s views on the metaphysics of the human person, recognizes that argument alone is inadequate to the task of educating the reader on the proper care of the soul, and that Dante’s effective use of images, makes the abstract Aristotelian concept of justice vivid and attractive, and its opposite repulsive.

Kant’s subject as source of universality and necessity in human understanding is Modern Philosophy's solution to the old problem of the universals, a solution which appeared to supersede once and for all the Aristotelian theory of abstraction. The present paper intends to show how Aquinas's Aristotelian doctrine on abstraction may stand the Kantian challenge and resolve the old problem when three principles are brought into play: 1) the same perfection can subsist in two different modes of (...) being, and thus the universal content of knowledge can be present in the particular reality (Summa, I, 84, 1); 2) things which are really distinct between themselves can be known in their distinction, even when they cannot exist separately (metaphysical distinction justifies gnoseological separation); 3) as Cornelio Fabro suggests, it is artificial to separate in the object of experience the object’s different levels of objectivity (quality, configuration and meaning) and, as a result, human experience could be considered the source not only of sensible content but also of intelligible content. This “defense” of Thomistic abstraction intends to offer an account of knowledge which reunites again epistemology with common sense experience, so that philosophy may no longer be a Platonic abstraction but a meaningful explanation of life.

Formal abstraction is a key instrument Aquinas employs to secure the possibility of mathematics conceived as a theoretical Aristotelian science. In this concept, mathematics investigates quantitative beings, which are grasped by means of formal abstraction in their necessary, universal, and changeless properties. Based on this, the paper divides into two main parts. In the first part (section II) I explicate Aquinas’s conception of (formal) abstraction against the background of the Aristotelian theory of science and mathematics. (...) In the second part (section III) I present and critically assess the problems associated with formal abstraction in mathematics. With all due respect to Aquinas’s genius, I find his conception of formal abstraction (as well as mathematics) unsatisfactory and list the main reasons for its failure in the conclusion. (shrink)

Medieval Integration Challenge for Intellection (MICI) in Albert the Great, Siger of Brabant, and Radulphus Brito.

The aim of this essay is to emphasize a number of important points that will provide a better understanding of the history of philosophical thought concerning scientific knowledge. The main points made are: (a) that the principal way of viewing abstraction which has dominated the history of thought and epistemology up to the present is influenced by the original Aristotelian position; (b) that with the birth of modern science a new way of conceiving abstraction came into being (...) which is better characterized by the term idealization, the name that was later, in fact, to be used by scientists to describe their scientific activity; (c) that, however, on account of the influence of empirical and inductive philosophy, scientists have often not had sufficient methodological awareness of this new way of viewing abstraction; (d) that this new concept of abstraction has frequently been expressed in the framework of philosophies that lie outside the mainstream of contemporary epistemology or even exhibit marked anti-scientific tendencies; (e) that the theme of idealization has been taken up again in the last few decades and a great contribution in this direction has been made by the so-called Pozna school of methodology.

In Canions be Causes, David Johnson defends the view that abstractions can have causal force. He offers as his own example of natural kinds ecological niches, arguing that the causal force of these niches in nature is akin to the force of Aristotelian final causes. He concludes that, rooted as it is in seventeenth century mechanism, the currently-accepted model of causality which recognises only efficient causes is inadequate to the needs of contemporary science. In Natural Kinds and Ecological Niches (...) — Response to Johnson ''s Paper, Melinda Hogan offers a critique of Johnson ''s paper which, by begging the question in favor of the very sort of causality Johnson seeks to supplement, misses the epistemological implications of his idea.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 127-128 [Access article in PDF] Dennis Des Chene. Life's Form: Late Aristotelian Conceptions of the Soul. Ithaca, NY: Cornell University Press, 2000. Pp. viii + 220. Cloth, $45.00. The history of philosophy aims at the recovery and interpretation of past thought, and its reconstructions seek to avoid anachronism. Dennis Des Chene's book is exemplary in this respect. It offers a (...) sophisticated and accurate report on Late Scholastic views and arguments about life and its form and principle, the soul. It is full of subtle and informed discussions of texts from, principally, Francisco Toledo, Pedro Fonseca, the commentators from Coimbra, Francisco Suárez, and Rodrigo de Arriaga.But the aim of the history of philosophy is philosophical and not exclusively historical. Recovery of the past is, for the historian of philosophy, at the service of contemporary understanding. The Late Scholastic authors studied by Des Chene understood this to be so. Suárez, for instance, distinguished between those doctrines and inquiries which are "antiquated (antiquatae) and wholly relegated from philosophy" and those which are not (Metaphysical Disputations, "Copious Index to Aristotle's Metaphysics," Book I, ch. 7). Unfortunately, when judged from this perspective, Des Chene's book is not as successful.In spite of its many comparisons between current debates, Descartes's views, and Late Scholastic doctrines, the book does not succeed in extracting much by way of genuine philosophical insight. Though well-informed and intelligent, for the most part these glosses are mere statements of Late Scholastic views in contemporary terms. But correctly describing alchemical theories from the point of view of modern chemistry does not make them any less archaic.This book is indeed more a contribution to the history of ideas or of science than to the history of philosophy. To be fair, it is true that, first, as such it is a most valuable contribution; second, much of what Late Scholastics had to say about life and the soul is indeed antiquated; third, even if philosophically antiquated, an adequate grasp of Late Aristotelian thought on these matters is necessary to understand Descartes and subsequent developments; and finally, the kind of informed historical recovery that Des Chene has provided here is a necessary condition for whatever philosophical lessons could be gained from these texts.Life's Form is divided into four parts. The first, "Data for the Study of Souls," looks at the phenomena which the Late Aristotelians sought to understand and explain, recovering both their grasp of the place of the living among other substances, and the constraints, [End Page 127] originating both from accumulated experience and from Christian faith, to which they were subject.The second part, "Defining the Soul," first examines the question of how to define life. It then looks at the definition of the soul as "first act of an organic or potentially living physical body"—whether the soul is an accident of the body, an entirely separate substance, or the substantial form of the body. Here one finds addressed the question whether there is a form of the body separate from the soul, or whether strictly the body has only one form, the soul. The issue of cadaveric forms, peculiar forms of corpses arising after death and the departure of the soul, comes up here. In the last section of this part Des Chene examines the definition of the soul as a principle of life and the relation, both epistemological and ontological, between this definition in terms of the operations of the soul, and the earlier one of the soul as form, that is, in terms of its being.Part 3, "Powers and Parts," looks at the vegetative (nutritive, reproductive, and augmentative), animal (sensitive), and spiritual (intellective) powers of the soul. Des Chene examines the criteria for distinguishing between powers, the relation between the one soul and its many powers, and the unity of the soul. "Unity," the fourth part of the book, takes up this last topic. It looks at the vegetative, sensitive, and intellectual powers as "parts" of the... (shrink)

Although Aristotle did not mention it, integrity can be understood in an Aristotelian framework. Seeing it in these terms will show that it is an executive virtue which concerns the existential well being of an agent. This analysis is not offered as an exegesis of Aristotle's text, but as an attempt to use an Aristotelian framework to understand a virtue deemed important today. This account will have the benefit of solving some problems relating to motivational internalism and, as (...) such, will contribute to that recent current of thought which has been highlighting the importance of virtue thinking in moral theory. I will distinguish moral judgement from decision and show that moral judgement is dependent upon virtue more strongly than it is upon impartial rationality. I will suggest that integrity is the virtue to which moral judgement gives expression and is the virtue which links judgement to decision so as to overcome akrasia. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Agent-Centered Morality: An Aristotelian Alternative to Kantian InternalismDaniel E. PalmerGeorge W. Harris. Agent-Centered Morality: An Aristotelian Alternative to Kantian Internalism. Berkeley: University of California Press, 1999. Pp. xi + 434. Cloth, $60.00.Contemporary philosophers have found substantial resources in the ethical writings of both Aristotle and Kant. Together Aristotelian-inspired virtue ethics and Kantian constructivism have not only contributed greatly to the resurgence of interest in normative (...) theory in recent decades, but have also provided the most prominent alternatives to the utilitarianism that has dominated Anglo-American ethics for so long. However, the development of these ethical projects has been carried out largely independently of one another. In Agent-Centered Morality, George Harris helps to overcome this lacuna by comparing and contrasting these two competing versions of [End Page 449] morality. As such, this work is a welcome addition to the literature both as a survey of recent work in Aristotelian and Kantian ethics as well as an account of the many ways in which they converge and diverge in their corresponding treatments of practical rationality.Harris begins by noting that the appeal of both the Aristotelian and Kantian models is that they attempt to generate a foundation for ethics within an account of practical reason, and thus to ground morality within a deliberative perspective that connects the demands of morality with an agent's own meaningful commitments. As such, Harris correctly argues that these projects have much more in common than has sometimes been supposed. The central question that Harris raises in this book is which account of practical reason is best suited for this task. His thesis is that the Aristotelian model gives us a more plausible picture of the role of norms within practical rationality.The major distinction between the Aristotelian and the Kantian models according to Harris is that while on the Aristotelian model the norms made use of in practical judgments are symmetric in their regulative function, the Kantian model provides an asymmetrical account of norms. To arbitrate between these two views, Harris proposes an integration test. The point of the integration test is to assure that our account of practical rationality and the function of regulative norms that it provides can support the integrity of rational agents. Minimally then, the test will favor the account of practical rationality that best "integrates the various concerns of rational human agents in a way that preserves integrity" (32).While the above vastly simplifies Harris's rich treatment of this issue, it nonetheless allows us to see how Harris goes about arguing for the superiority of the Aristotelian view. For Harris maintains that the Aristotelian symmetrical model integrates regulative norms better than the Kantian model. To show why, Harris makes use of a number of examples to demonstrate that regulative norms function in a symmetrical fashion in regards to one another for the agent of integrity. For instance, to show that the norm of impartial respect is sometimes regulated by the norm of impartial sympathy, Harris gives an example of someone who breaks a lunch date in order to help a dog that is being mistreated. Likewise, Harris uses examples to argue that sometimes even partial norms, like that of parental concern, regulate the impartial norm of respect. Harris believes that these cases demonstrate that the regulative norms made use of in practical deliberation must function in a symmetrical fashion. Thus, Harris thinks we have good reason to reject the Kantian view "that the integrative function of practical reason is achieved by an impartial norm that is asymmetrical in its regulative function" (127).Though interesting and worthy of attention, I am not convinced that Harris makes use of the most plausible understanding of the Kantian model of practical rationality in his central argument. By focusing almost exclusively upon the idea of respect, Harris assumes that the best reading of the Kantian project will be founded primarily in the idea of impartial respect. However, if we adopt a procedural understanding of the Categorical Imperative, a plausible case could be made that a Kantian account of practical rationality can account for the examples that Harris makes use of just as well as the Aristotelian...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Basic Concepts of Aristotelian PhilosophyShawn LohtMartin Heidegger. Basic Concepts of Aristotelian Philosophy. Translated by Robert D. Metcalf and Mark B. Tanzer. Bloomington-Indianapolis: Indiana University Press, 2009. Pp. xii + 279. Cloth, $39.95.Previously available as Volume 18 of the Gesamtausgabe [GA], this text contains a lecture course delivered by Heidegger at Marburg during the summer of 1924. Metcalf and Tanzer's translation is its first appearance in English. (...) The editor of this volume in the Gesamtausgabe reports that only a fraction of Heidegger's original course material survives in manuscript form. As a result, much of the text does not originate from Heidegger's own hand. The bulk of it represents a transcription of the lecture course based on multiple independently-recorded, complete sets of student notes in conjunction with Heidegger's extant course papers. However, the resulting text reads as continuously as Heidegger's other better-preserved lecture courses from the 1920s, and should be regarded as a legitimate source for studying early Heidegger. Only the reproduction of Heidegger's notes for the course appears in rough outline form, comprising approximately 50 pages, so readers should not anticipate a text consisting entirely of abbreviated sketches as one sees, for instance, in the recently translated Basic Concepts of Ancient Philosophy (GA 22).The content of the lecture course is not devoted to enumerating the basic Aristotelian concepts per se, but rather to accounting for the phenomenological dimensions of the Greek experience in which conceptuality as such could arise. However, Heidegger does treat most principal concepts of Aristotelian philosophy here, describing the ontological framework from which they originate and their interrelations with one another.Heidegger engages with Kant in the early sections of the course in order to locate the historical solidification of the concept as a guiding idea in philosophy, but he moves to Aristotle quickly on the premise that the decisive germ of conceptuality is exhibited in the Greek discovery of the significance of definitions. In the text that follows, Heidegger takes up central themes in Aristotle in order to unfold Greek being-in-the-world as occurring through language and, particularly, oral discourse. Strong focus is placed on Greek being-there in its everydayness as the hermeneutic for understanding conceptuality.Clear rudiments of the terminology of Being and Time emerge in the course of Heidegger's account of Aristotle. Themes appearing in that later work, including world, being-with-one-another, attunement, fear, and idle talk, inform Heidegger's reading of the Aristotelian account of human nature across the Nicomachean Ethics, Rhetoric, De Anima, and Parts of Animals. Key Aristotelian terms Heidegger develops within this framework include 'prohairesis', 'hexis', 'pathos', and 'nous'. Early formulations of Heidegger's conceptions of logos and aletheia and their fundamental role in Greek experience also permeate his reading. Traces of Heidegger's more mature phenomenology are evident in the lecture course's late sections, in which he takes up the Aristotelian account of motion in the Physics. Here, Heidegger emphasizes the roles of nous as constitutive of the human agent's openness to the world and of kinesis as the fundamental mode in which beings come into view for the Greeks.Notable among the translation choices of Metcalf and Tanzer is their rendering of 'Dasein' and its variants. As they write in the Translators' Preface, Heidegger's use of this term in the lecture course reflects an understanding of Dasein in terms of its there-character. The result places less emphasis on the human subject as a dative agent of manifestation, as one sees in Being and Time, highlighting instead the manner in which Dasein finds itself in the world. This last is expressive of Heidegger's emphatic treatment in the course of conceptuality as tied up with human being-in-the-world.This text will be of vital interest to scholars interested in the genesis of Being and Time and Heidegger's early formulations of its central arguments in the 1920s. The text will also be an important addition to Heidegger's works on Aristotle available in English. The lecture course offers penetrating and incisive accounts of themes in Aristotle that Heidegger neglects or treats only briefly... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Coloration of Aristotelian Eye-Jelly: A Note on On Dreams 459b–460aRaphael WoolfThe purpose of this paper is to make a small contribution to a recent lively debate concerning Aristotle’s philosophy of mind. This debate has centered on a paper published by Myles Burnyeat,1 which argued that Aristotle’s philosophy of mind, being hopelessly anachronistic, could not serve as the prototype of any contemporary theory: in particular, it could not (...) be seen as proto-functionalist, as Nussbaum and Putnam had proposed.2 The grounds given by Burnyeat for the anachronism of Aristotle’s philosophy of mind focus mainly on Aristotle’s notion of perceptual awareness. According to Burnyeat, perceptual awareness is for Aristotle a primitives3 and essential4 property of the relevant organ of perception. In Burnyeat’s view, Aristotle’s theory denies that there is any further level of analysis that can be undertaken. When an eye comes to perceive an object, the potentiality of the eye for seeing is actualized, but there is nothing further to be said. In particular, there is no physiological change taking place in the eye, in which the psychological change is realized. Thus, when Aristotle says in the De Anima that the eye becomes “in a way coloured”5 when it sees a coloured object, for Burnyeat this means no more [End Page 385] than that it registers awareness of colour,6 not that it becomes literally coloured itself.On this last point, Burnyeat takes issue with the view of Richard Sorabji,7 who maintains that for Aristotle the eye does undergo physiological change when it does some seeing: in particular, if it sees, for example, a red object, then the jelly inside the eye literally becomes coloured red. On this view, Aristotle does indeed have a theory, congenial enough to modern perspectives, whereby each psychological change is realized physiologically.8There are several large questions which my paper does not attempt to address. Firstly, it offers no view on what implications Burnyeat’s position would have, if correct, for the interpretation of Aristotle as a proto-functionalist. Secondly, it does not offer a view on how necessary the correctness of an interpretation such as Sorabji’s is to the case made by the advocates of Aristotle as a proto-functionalist.9 Thirdly, it makes no adjudication between any of the competing parties’ interpretations of Aristotle’s De Anima, his main work on psychology and the chief textual battleground in the debate I have been outlining.This paper’s aim is a much more modest one. It is to draw attention to a short passage in Aristotle’s work On Dreams, which in my view incontrovertibly suggests that Aristotle did believe that the eye becomes literally coloured during perception of a coloured object. I shall therefore be presenting one piece of evidence in favour of Sorabji’s view; but I shall not be arguing that Sorabji’s view is conclusively the right one (which would require consideration of all the relevant evidence), nor drawing any conclusions about the implications of this evidence for interpretations of Aristotle’s philosophy of mind. It is, however, [End Page 386] reasonable to suggest that if Sorabji’s view is right then Burnyeat’s view is in severe difficulties, since its main underpinning—the claim that psychological change has no physiological counterpart in Aristotle’s theory—will have been removed. The evidence I have to present, then, is, albeit indirectly, support for the view that Aristotle’s philosophy of mind is not hopelessly anachronistic, at least in the way that Burnyeat claims.Here is the evidence from On Dreams (459b23–460a26):That the sense-organs rapidly perceive even slight differences is shown by what happens with mirrors. Indeed, anyone who would give his attention to it might look into that subject too and explore the problem. At the same time, it is clear from this case that, just as the organ of sight is affected by, so too it acts upon, its object. For in extremely clean mirrors, when women look into them during their menstrual period, the mirror surface takes on a sort of blood-red cloud. In fact, if the... (shrink)

Frege suggests that criteria of identity should play a central role in the explanation of reference, especially to abstract objects. This paper develops a precise model of how we can come to refer to a particular kind of abstract object, namely, abstract letter types. It is argued that the resulting abstract referents are ‘metaphysically lightweight’.

One often hears extravagant claims made for the Aristotelian doctrine that "what understands and what is understood are the same" De anima iii.4; 430a4). This identity between knower and what is known, or between percipient and what is perceived, is often said to offer a way out of the familiar skeptical arguments against the possibility of our having knowledge of the external world. Typically such claims are made by students of Thomas Aquinas, who in this way seek to render (...) Aquinas's theory of knowledge immune from the skeptical and idealist controversies of modern philosophy. In this paper I argue that Aquinas put this doctrine of identity to no such use, that in fact he explicitly rejects any such use of the doctrine, and that furthermore no plausible reading of the doctrine could conceivably produce such dramatic results.

Words have determinable sense only within a complex of unstated assumptions, and all interpretation must therefore go beyond the given material. This book addresses what is man's place in the Aristotelian world. It also describes man's abilities and prospects in managing his life, and considers how far Aristotle's treatment of time and history licenses the sort of dynamic interpretation of his doctrines that have been given. The ontological model that explains much of Aristotle's conclusions and methods is one of (...) life-worlds, in which the material universe of scientific myth is no more than an abstraction from lived reality, not its transcendent ground.

RESUMEN La comprensión aristotélica de la prudencia constituye un antecedente fundamental para entender el giro hermenéutico de la fenomenología heideggeriana. Se examina cómo la interpretación fenomenológica de Heidegger sobre esta virtud dianoética puede entenderse si se consideran a cuatro aspectos: la prioridad de la praxis respecto de los saberes teóricos, el reconocimiento de un horizonte de verdad más amplio que la verdad proposicional del logos apophantikos, el valor del instante kairológico en el que discurre la acción humana y el anticipo (...) de la temporalidad y, cómo no, la importancia de la finitud, la libertad y la autenticidad del existir fáctico del hombre. ABSTRACT Aristotle's conception of phronesis is crucial in order to understand the hermeneutic turn in Heidegger's phenomenology. The article examines how Heidegger's phenomenological interpretation of this dianoetic virtue could be understood if four aspects are taken into account: the priority of praxis over theoretical knowledge, the recognition a horizon of truth that is broader than the propositional truth of the logos apophantikos, the importance of kairos, in which human action occurs, and the anticipation of temporality, and, of course, the importance of the finitude, freedom, and authenticity of man's factual existence.

It has been pointed out that St. Albert the Great, in defining the human soul as it is in itself, turns to Avicenna rather than to Aristotle. There is, he says, a twofold definition of the human soul, one in relation to the body according as it is the act and mover of a body, and one in itself according as it is a substance. And it is better to speak of the soul as a perfection than as a form, (...) since forma signifies something essentially related to matter, whereas perfectio does not; and the soul, as substance, can subsist without a body as a sailor can without a ship. Indeed, the only difference between the soul and an angel is that the soul ‘is inclined’ to a body as its act, whereas an angel is not. The Aristotelian definition of the soul as form has application to the soul in its relation to the body; but to express what the soul is in itself we must turn to the Avicennian definition of the soul as perfection.

ABSTRACT My aim in this paper is to challenge the neo-Aristotelian tradition, currently dominant in contemporary theories of virtue education, by proposing the Platonic pedagogical methodology for virtue cultivation as a worthy alternative to the Aristotelian theory of education. I highlight that, in contrast to Aristotle’s limited remarks concerning virtue education, Plato conceptualizes and develops a rigorous educational theory in the Republic that considers many different facets of education – i.e. moral character education, intellectual character education, exemplarism and (...) educational corruption. Given Plato’s immense contribution to virtue education theory, I conclude that his educational program merits more attention. It can serve as inspiration both for improving existing theories of character education and for developing new ones. (shrink)

The paper is a study of the logic of existence, negation, and order in the Neoplatonic tradition. The central idea is that Neoplatonists assume a logic in which the existence predicate is a comparative adjective and in which monadic predicates function as scalar adjectives that nest the background order. Various scalar predicate negations are then identifiable with various Neoplatonic negations, including a privative negation appropriate for the lower orders of reality and a hyper-negation appropriate for the higher. Reversion to the (...) One can then be explained as the logical inference of hyper-negations from mundane knowledge. Part I develops the relevant linguistic and logical theory, and Part II defends Wolfson and the scalar interpretation against the more traditional Aristotelian understanding of Whittaker and others of reversion as intensional abstraction.

Given the many differences among women, can feminist theory even speak in terms of the category "woman?" This is the question that currently dominates feminist theory. Theorists who subscribe to traditional feminism argue that feminism must, for political and philosophic reasons, employ the category "woman." Those who take a poststructuralist approach, however, assert that invoking "woman" is an oppressive tactic that advances an essentialist ideal that is oppressive to women no matter what the content of that ideal. Even a "feminist" (...) understanding of "woman" does violence to difference, they charge. Based on the many different ways in which any abstraction manifests itself concretely, they determine that the abstraction is a myth and reality is in fact radically contingent and discursively constructed; it is an ever-shifting field. We can never claim to "know" woman because to know her is only to know she is not knowable. Knowledge has no connection to any stable "being." ;This branch of feminist theory has gained increasing ascendance; currently, the charge of "essentialism" is almost enough to undermine the legitimacy of any feminist theory, no matter what other merits it may possess. But many feminists are uneasy with poststructuralism's depiction of reality and its implications: the impossibility of knowledge and the impossibility of political discourse which invokes an understanding of truth or the good. Yet neither do these traditional feminists wish to foreclose continued questioning. Some feminists try to combine the insights of poststructuralism, and the preservation of questions, with more traditional understandings of knowledge, the subject and reality. They assert that we must somehow combine both contingency and stability in our understanding of "woman." But they do not fully articulate of how both contingency and stability coexist, or how difference and unity coexist. These issues are addressed at length by Aristotle in his Metaphysics, from which feminists can learn a great deal about these tensions. Aristotle is not "traditional" in the simplistic way that he is often portrayed to be. His understanding of being combines many of the insights claimed by poststructuralism without severing the connection between knowledge and being. (shrink)

In An Aristotelian Realist Philosophy of Mathematics Franklin develops a tantalizing alternative to Platonist and nominalist approaches by arguing that at least some mathematical universals exist in the physical realm and are knowable through ordinary methods of access to physical reality. By offering a third option that lies between these extreme all-or-nothing approaches and by rejecting the ‘dichotomy of objects into abstract and concrete’, Franklin provides potential solutions to many of these traditional problems and opens up a whole new (...) terrain for debate in the philosophy of mathematics.

Aquinas’s process of abstraction of the particular thing into a universal concept is of pivotal importance for grounding his philosophy and theology in a natural framework. Much has been said and written regarding Aquinas’s doctrine of abstraction, yet recent studies still consider it to be ‘nothing more than a kind of magic.’ This problematic claim is not without foundation, for in trying to understand exactly how this process works, we are constantly faced with an unbridgeable abyss and the (...) repeated vague explanations made by Aquinas. The plain truth is that Aquinas explains what abstraction ought to do and yet, most of the time, he does not explain how it is to be done. This paper intends to show that although Aquinas does not present us with a mechanism for the theory of abstraction, we are nevertheless able to construct a viable mechanism which accords with Aquinas’s guidelines. The aim of constructing a working mechanism that corresponds to what Aquinas demands of the process of abstraction is twofold: First, it attempts to extricate Aquinas’s doctrine of abstraction from the claims of being a quasi-natural doctrine. Second, a viable process of abstraction which is derived from Aquinian-Aristotelian sources can approach contemporary cognitive problems from a fresh point of view. (shrink)

ABSTRACT:This article proposes a theory of the firm based on the common good. It clarifies the meaning of the term “common good” tracing its historical development. Next, an analogous sense applicable to the firm is derived from its original context in political theory. Put simply, the common good of the firm is the production of goods and services needed for flourishing, in which different members participate through work. This is linked to the political common good through subsidiarity. Lastly, implications and (...) challenges arising from the positing of work as the common good of the firm are explored. (shrink)
