There is a certain conventional interpretation of Aristotle's argument, inMetaphysicsΛ.7, for the identification of the first unmoved mover as God, according to which that argument has the following outline.

This essay argues the Stoics are rightly regarded as pantheists. Their view differs from many forms of pantheism by accepting the notion of a personal god who exercises divine providence. Moreover, Stoic pantheism is utterly inimical to a deep ecology ethic. I argue that these features are nonetheless consistent with the claim that they are pantheists. The essay also considers the arguments offered by the Stoics. They thought that their pantheistic conclusion was an extension of the best science of their (...) day. Some of their most interesting arguments are thusa posteriori. (shrink)

There is no general agreement among scholars that Aristotle had a unified concept of phantasia. That is evident from the most cursory glance through the literature. Freudenthal speaks of the contradictions into which Aristotle seems to fall in his remarks about phantasia, and explains the contradictions as due to the border position which phantasia occupies between Wahrnehmung and thinking. Ross, in Aristotle, p. 143, talks of passages on phantasia in De Anima 3. 3 which constitute ‘a reversal of his doctrine (...) of sensation’ and perhaps do not ‘represent his deliberate view’. This is a serious state of affairs, since De Anima 3. 3 is Aristotle’s main discussion of phantasia. Of passages on phantasia, appearances and images in De Anima 3. 3, Hamlyn says: ‘There is clearly little consistency here’. Even Schofield, who is more optimistic about saving the unity of Aristotle’s concept than the last two scholars, grants that ‘some of the inconsistencies of Aristotle’s account seem more than merely apparent’.1 He thinks of Aristotle’s phantasia as a ‘loose-knit, family concept’. My purpose here is to suggest that Aristotle is more consistent in his use of phantasia than his critics will allow him to be. The translation of the term as imagination frequently adds unnecessarily to the confusion, so I shall avoid it and use transliteration instead. (shrink)

I demonstrate here how Aristotle's teleological conception of nature has been largely misunderstood in the scientific age and I consider what his view might offer us with regard to the environmental challenges we face in the 21st century. I suggest that in terms of coming to an ethical understanding of the creatures and things that constitute the ecosystem, Aristotle offers a welcome alternative to the rather instrumental conception of the natural world and low estimation of subjective experience our contemporary techno-scientific (...) culture espouses. Among other things, I consider how his conception of orexis and eudaimonia might be extended to include the eco-system itself, thus allowing us to better understand the moral meaning of nature. I conclude with a look at the way in which modern phenomenology re-addresses the fundamental Greek concern with ontology, meaning and human authenticity. I consider the ways in which phenomenology reasserts the value of direct human experience that was so important to Aristotle; and I consider how this view, and that of Deep ecology, may help us to experience nature - and all of Being for that matter - in a more authentic, meaningful and altogether ethical light.

In cognitive science, the dynamical systems theory (DST) has recently been advocated as an approach to cognitive modeling that is better suited to the dynamics of cognitive processes than the symbolic/computational approaches are. Often, the differences between DST and the symbolic/computational approach are emphasized. However, alternatively their commonalities can be analyzed and a unifying framework can be sought. In this paper, the possibility of such a unifying perspective on dynamics is analyzed. The analysis covers dynamics in cognitive disciplines, as well (...) as in physics, mathematics and computer science. The unifying perspective warrants the development of integrated approaches covering both DST aspects and symbolic/computational aspects. The concept of a state-determined system, which is based on the assumption that properties of a given state fully determine the properties of future states, lies at the heart of DST. Taking this assumption as a premise, the explanatory problem of dynamics is analyzed in more detail. The analysis of four cases within different disciplines (cognitive science, physics, mathematics, computer science) shows how in history this perspective led to numerous often used concepts within them. In cognitive science, the concepts desire and intention were introduced, and in classical mechanics the concepts momentum, energy and force. Similarly, in mathematics a number of concepts have been developed to formalize the state-determined system assumption [e.g. derivatives (of different orders) of a function, Taylor approximations]. Furthermore, transition systems - a currently popular format for specification of dynamical systems within computer science - can also be interpreted from this perspective. One of the main contributions of the paper is that the case studies provide a unified view on the explanation of dynamics across the chosen disciplines. All approaches to dynamics analyzed in this paper share the state-determined system assumption and the (explicit or implicit) use of anticipatory state properties. Within cognitive science, realism is one of the problems identified for the symbolic/computational approach - i.e. how do internal states described by symbols relate to the real world in a natural manner. As DST is proposed as an alternative to the symbolic/computational approach, a natural question is whether, for DST, realism of the states can be better guaranteed. As a second main contribution, the paper provides an evaluation of DST compared to the symbolic/computational approach, which shows that, in this respect (i.e. for the realism problem), DST does not provide a better solution than the other approaches. This shows that DST and the symbolic/computational approach not only have the state-determined system assumption and the use of anticipatory state properties in common, but also the realism problem.

Like many realists about causation and causal powers, Aristotle uses the language of necessity when discussing causation, and he appears to think that by invoking necessity, he is clarifying the manner in which causes bring about or determine their effects. In so doing, he would appear to run afoul of Humean criticisms of the notion of a necessary connection between cause and effect. The claim that causes necessitate their effects may be understood—or attacked—in several ways, however, and so whether the (...) view or its criticism is tenable depends on how we understand the necessitation claim. In fact, Aristotelian efficient causation may be said to involve two distinct necessary connections: one is a relation between causes considered as potential, while the other relates them considered as active. That is, the claims that (1) what has the power to heat necessarily heats what has the power to be heated, and that (2) a particular flame which is actually under a pot necessarily heats it, both of which appear to be true for Aristotle, involve distinct notions of necessity. The latter kind of necessity is based on the facts, as Aristotle sees them, about change, whereas the former is based in the nature of properties. Though different, both kinds of necessity are instances of what contemporary philosophers would call metaphysical necessity, and together they also amount to a theory of causal determination.

Galen's æuvre presents a remarkably varied body of texts–varied in subject matter, style, and didactic purpose. Logical tracts sit alongside tomes of drug–lore; handbooks of dietetics alongside anatomical investigations; treatises of physiology alongside ethical opuscula. These differences in type have received some, though as yet insufficient, scholarly attention. Mario Vegetti demonstrated the coexistence of two ‘profili’ or images of the art of medicine: Galen presents the art as an Aristotelian deductive science, on the one hand, and as a technician's craft, (...) on the other. The former image, offering an ambitious elevation of the doctor's cultural status, has medicine as a philosophical episteme analogous to the mathematical sciences, exercised above all to provide causal accounts and logical demonstrations, and centred on the knowledge of anatomy. The second image is that of the clinician, concerned with the body in its pathological manifestations and using as its prime model the ‘pre-anatomical’ theory of the humours. And the content of the treatises shifts in relation to this dual image: ‘profilo alto’ and ‘profilo basso’ are reflected in different types of work. Polemical writings such as the Protrepticus, as well as the great treatises of anatomy and physiology, De usu partium and De naturalibus facultatibus, present medicine in the former light, while works like De temperamentis or Quod animi mores base themselves on humoral pathology and accord with the earlier, artisan-like image.

In the second century of our era the Athenian Platonist, Atticus, claimed that it was clear not only to philosophers but perhaps even to ordinary people that the heritage left by Plato was the immortality of the soul. Plato had expounded the doctrine in various and manifold ways (ποικίλως καì παντοίως) and this was about (σχεδόν) the only thing holding together the Platonic school. Atticus is but one witness to the prominence accorded the soul in discussions and debates among later (...) Platonists. But while questions concerning the origin, constitution, and destiny of the human soul are relatively well attested for Middle Platonism, not to mention Neoplatonism, we know much less about these topics among Plato's immediate successors in the Academy, Speusippus of Athens (c. 408–339) and Xenocrates of Chalcedon (396–314). Both wrote treatises on the soul (περì ψυχ⋯ς), but these have been lost along with their other, numerous writings. Because the least that can be said is that Speusippus and Xenocrates upheld the immortality of the soul (as would be expected), any snippet of information that might tell us more deserves close consideration.

ABSTRACT:In response to criticism of empirical or “positive” approaches to corporate social responsibility (CSR), we defend the importance of these approaches for any CSR theory that seeks to have practical impact. Although we acknowledge limitations to positive approaches, we unpack the neglected but crucial relationships between positive knowledge on the one hand and normative knowledge on the other in the implementation of CSR principles. Using the structure of a practical syllogism, we construct a model that displays the key role of (...) empirical knowledge in fulfilling a firm’s responsibility to society, paying special attention to the implications of the “ought implies can” dictum. We also defend the importance of one particular class of empirical claims; namely, claims from the field of economics. Even positive economic theory, which is often criticized for endorsing profits rather than values, can cooperate in intriguing ways with non-economic concepts in the implementation of CSR goals.

There is quite a long-standing tradition according to which the morally proper treatment of animals does not rely on what we owe them, but on our benevolence. Nussbaum wishes to go beyond this tradition, because in her view we are dealing with issues of justice. Her capabilities approach secures basic entitlements for animals, on the basis of their fundamental capacities. At the same time Nussbaum wishes to retain the possibility of certain human uses of animals, and to see them as (...) morally justifiable. This article shows that these things do not go together with her capabilities approach to animal rights. More specifically, they clash with the attitude towards animals that Nussbaum's approach intends to foster in human beings. (shrink)

Plant and animal species are information-processing entities of such complexity, integration, and adaptive competence that it may be scientifically fruitful to consider them intelligent. The possibility arises from the analogy between learning and evolution, and from recent developments in evolutionary science, psychology and cognitive science. Species are now described as spatiotemporally localized individuals in an expanded hierarchy of biological entities. Intentional and cognitive abilities are now ascribed to animal, human, and artificial intelligence systems that process information adaptively, and that manifest (...) problem-solving abilities. The structural and functional similarities between such systems and species are extensive, although they “are usually obscured by population-genetic metaphors that have nonetheless contributed much to our understanding of evolution.In this target article, I use Sewall Wright's notion of the “adaptive landscape” to compare the performances of evolving species to those of intelligent organisms. With regard to their adaptive achievements and the kinds of processes by which they are achieved, biological species compare very favorably to intelligent animals by virtue of interactions between populations and their environments, between ontogeny and phylogeny, and between natural, interdemic, organic, and species selection. Addressing the question of whether species are intelligent could help to refine our ideas about species, evolution, and intelligence, and could open new lines of empirical and theoretical inquiry in many disciplines.

This Article doDespite obvious differences in the Aristotelian and Stoic theories of responsibility, there is surprisingly a deeper structural similarity between the two. The most obvious difference is that Aristotle is (apparently) a libertarian and the Stoics are determinists. Aristotle holds adults responsible for all our "voluntary" actions, which are defined by two criteria: the "origin" or cause of the action must be "in us" and we must be aware of what we are doing. An "involuntary" action, for which we (...) are not responsible, is one that fails to meet either one of these two criteria. Aristotle is a libertarian insofar as he insists that all voluntary actions are "in our power" to perform or not. As determinists the Stoics cannot admit this sort of freedom, but they still consider the agent to be a vital link in the chain of events, so they redefine what is "in our power" as what comes about "through us." The terminology is different, but I argue that these actions, for which the Stoics hold us responsible, are in fact coextensive with Aristotle's voluntary actions. An "impression" is the first necessary condition for action, and is a sort of visual image of the object stimulating one to act. The right sort of impression activates the agent's "impulse," an internal movement of soul or mind, which is the direct cause of action. But impulse is always accompanied by "assent," which is the mind's affirming the truth of the proposition that we ought to go after the object stimulating our impulse. Thus, since assent is a necessary condition for action, we always act knowing what we are doing. This means that all actions caused by our own impulse and assent are by Aristotle's criteria voluntary, where impulse provides the internal origin of the action and assent provides the awareness of what is being done. I conclude that the Stoic and Aristotelian classes of what one is responsible for are coextensive, their criteria defining responsible actions are nearly identical, and the only substantial difference is that Aristotle claims such actions are in our power to do or not do while the Stoics say that such actions are necessitated (by our internal nature as well as external factors). es not have an abstract.

In thePolitics, Aristotle maintains, contrary to his predecessors, that there is a distinctive mode of authority that husbands should exercise over their wives. He even coins a word for it: γαμιϰή, ‘the marital art’ or ‘marital rule’ (Pol. 1.3, 1253b8–10; 1.12, 1259a37–9). Marital rule is supposed to differ from the authority that fathers have over their children and from the kind of rule that citizens exercise over one another. Yet it is not clear whether there is any conceptual space between (...) political and paternal rule for marital rule to occupy. Where fathers rule and children are ruled, citizens take turns ruling and being ruled. Husbands, however, either share their rule with their wives, or they do not. If they do not, then marital rule seems indistinct from paternal rule; if they do, then it seems indistinct from political rule. To add to the confusion, Aristotle says that husbands properly rule their wives politically, but without alternating in positions of ruling and being ruled. On its face, this idea seems flatly contradictory. Political rule just is shared, reciprocal rule, and so if the husband rules permanently and his wife is merely ruled, then his rule cannot be political. So Aristotle's own description of marital rule appears inconsistent, and in any case it is difficult to see how marital rule could have the distinctive character that he insists it does. (shrink)

There is a current debate about the grammar of intention: do I intend to φ, or that I φ? The equivalent question in Aristotle relates especially to choice. I argue that, in the context of practical reasoning, choice, as also wish, has as its object an act. I then explore the role that this plays within his account of the relation of thought to action. In particular, I discuss the relation of deliberation to the practical syllogism, and the thesis that (...) the conclusion of the second is an action. (shrink)

The author sets a goal to show the specificity of the formulation of universal prescriptive judgments about a virtuous act in the framework of Aristotelian ethical doctrine. To achieve this goal, Aristotle’s philosophy concept of practical wisdom is analyzed. It shows a necessity to distinguish the use of practical wisdom in a personal experience of the act and for forming the inter-subjective practical knowledge about making of a virtuous act. The specificity of ethics as practical knowledge and its difference from (...) individual moral experience are defined by means of the distinction of the use of practical wisdom. It also shows the limitations of practical syllogism as the main rational mechanism for the formation of inter-subjective practical knowledge. Additionally, the universal prescriptive judgments are divided into informative and functional: the former reveals the content of the action, the latter – its structure, that is, the former defines what a person must do, the latter defines what an action should be to comply with the right purpose, consequently, the right content. At the same time, the right content is recognized only in individual experience and can not be expressed universally, without losing its practical value. The author concludes that the formulation of informative universal prescriptive judgments is impossible within the framework of Aristotelian ethical doctrine. It is impeded by the unsolvable problem of the correlation between the general and the particular, the transition from descriptive judgments to prescriptive judgments. However, it is possible to formulate functional universal prescriptive judgments. They also constitute the methodological basis for criticism of the accepted in society moral norms, which are based on the past positive experience of actions. (shrink)

ABSTRACT This paper suggests a much more serious purpose for an education in music-making than play or pleasure or even the training of professional musicians. It presents and explicates a possible connection between musical performance training and the development of practical wisdom. Music in performance constitutes in effect a form of virtuous conduct, where one learns through doing and thereafter comes to love and to be capable of wise practical judgement. Excellence in this field requires the exercise of a species (...) of reasoning and judgement analogous to Aristotelian practical wisdom, and develops the distinctive qualities of character and vision of the practically wise person.

Duas das principais controvérsias que têm ocupado aqueles que se dedicam à teoria aris- totélica do movimento animal são a controvérsia acerca da forma da cognição através da qual um animal irracional apreende um objeto como um objeto de desejo e a controvérsia acerca da função desempenhada pela cognição na explicação aristotélica dos movimentos voluntários de locomoção animal. Neste artigo, eu apresento uma teoria acerca das formas como o desejo e a cognição se articulam na teoria aristotélica segundo a qual (...) um animal irracional apreende um objeto como um objeto de desejo através da percepção incidental deste objeto e, ao contrário do que a maioria parece acreditar, esta percepção não tem sempre a mesma função na produção destes movimentos. Se o que for dito aqui estiver correto, em alguns casos esta percepção é responsável tanto pela geração do desejo quan- to pela sua orientação, mas em outros ela é responsável apenas pela sua orientação.

Biology is the most extensive field in the Corpus Aristotelicum. In his fundamental work De anima, Aristotle tries to fix the borders of this life science. The term ψυχή has a twofold explanatory status. On the one hand, ψυχή is understood as a principle of all living beings. On the other hand, it is understood as a cause of the fact that all living beings are alive. The paper is divided into three sections. The first part shows why Aristotle discusses (...) these issues in a work entitled Περὶ ψυχῆς. Since Pythagoras and Heraclitus, ψυχή was understood as a life principle: Pythagoras believed that men, animals and plants share the same nature: they are all ἔμψυχα and they are homogenous qua ψυχή. The second part of this article deals with Aristotle’s definition of the soul in DA II: ψυχή is the principle of all living things. This establishes the external criteria to divide living and non-living beings and the internal criteria to divide living beings. The third part of this paper is concerned with the methodological consequences of this definition: the life functions are the central explanandum in Aristotle’s biology. De anima II defines such various life-functions as nourishment, sense-perception and locomotion. These capacities contour the main fields of the philosopher’s biological investigation. For Aristotle, the faculty of reproduction is a subtype of nourishment. Reproduction is the most important and most natural function of all living beings. Genetics is, therefore, the most important field in Aristotle’s biology. (shrink)

Aristotle is often credited with views about practical reasoning, desire, and action collectively referred to as the theory of the practical syllogism.Some commentators are skeptical about the existence of any such general theory, but most would agree that a theory of some sort is outlined in the De Motu Animalium and that it influences Aristotle’s account of akrasia in the icomachean Ethics.This paper will begin by describing the most important ideas in the De Motu Animalium discussion of the practical syllogism. (...) The ideas are simple but I think that their implications and philosophical importance have not been appreciated. I will suggest that the practical syllogism is Aristotle’s model for the rational explanation of action. Other commentators have made this claim, but I think that it can be given a very precise sense. Aristotle thinks that an action can be rationally explained if the agent acts in response to the strength of the reasons that he sees for acting. The practical syllogism is an argument that expresses the reasons in favor of the action, so if the agent acts for those reasons the action is explained by the practical syllogism. The second part of the paper considers the work that the practical syllogism does in Aristotle’s account of akrasia. I will argue that in akrasia—at least in the most extreme kind of akrasia—the agent acts intentionally to satisfy a desire but the action cannot be explained by a practical syllogism. Aristotle distinguishes between explanation by the motivational strength of desires and explanation by a practical syllogism. The last part of this paper comments on David Charles’s interpretation of Aristotle’s views about desire, practical reason, and akrasia. Charles discusses the traditionally disputed questions in a provocative way, and more importantly his suggestions fit together into a complex and philosophically sophisticated reading of Aristotle. I disagree with his most important claims, but I can best explain and defend my own interpretation by contrasting it with his. (shrink)

I offer a novel interpretation of Aristotle's psychology and notion of rationality, which draws the line between animal and specifically human cognition. Aristotle distinguishes belief (doxa), a form of rational cognition, from imagining (phantasia), which is shared with non-rational animals. We are, he says, “immediately affected” by beliefs, but respond to imagining “as if we were looking at a picture.” Aristotle's argument has been misunderstood; my interpretation explains and motivates it. Rationality includes a filter that interrupts the pathways between cognition (...) and behavior. This prevents the subject from responding to certain representations. Stress and damage compromise the filter, making the subject respond indiscriminately, as non-rational animals do. Beliefs are representations that have made it past the filter, which is why they can “affect [us] immediately.” Aristotle's claims express ceteris paribus generalizations, subject to exceptions. No list of provisos could turn them into non-vacuous universal claims, but this does not rob them of their explanatory power. Aristotle's cognitive science resolves a tension we grapple with today: it accounts for the specialness of human action and thinking within a strictly naturalistic framework. The theory is striking in its insight and explanatory power, instructive in its methodological shortcomings. (shrink)

It is argued that according to Aristotle the universe is a single substance with its own form and matter.

The concept of o or "pre-emotions" is known not only to the Roman Stoics and Christian exegetes but also to Philo of Alexandria. Philo also supplies the term o at QGen 1.79. As Philo cannot have derived what he knows from Seneca (despite his visit to Rome in 39), nor from Cicero, who also mentions the point, he must have found it in older Stoic writings. The o concept, rich in implications for the voluntariness and phenomenology of the passions proper, (...) is thus confirmed for the Hellenistic period. It is not to be expected that Philo's handling of this or any concept will necessarily conform to the usage of his Stoic sources. His evidence is nonetheless of great value where it coincides with that of other witnesses. In QGen 4.73 the emphasis falls upon involuntariness and the mechanisms of impression and assent as in Epictetus fr. 9. The o saves the virtuous person's insusceptibility to emotion exactly as it does for the Stoic spokesman in Gellius NA 19.1; this point is of some interest in view of the Christological use of this concept in Origen and Didymus. QGen 1.55 and 3.56 indicate that the occurrence of the o is dependent upon uncertainty, and further, that for Philo, as for Seneca in Ira 2.3.4, a thought not acted upon can count as a o. In QGen 4.15-17 and 1.79, Philo indicates that hope and perhaps laughter may be related to joy as o to o; these assertions are not paralleled in extant Stoic texts. Further, in QGen 2.57, he names "biting and contraction" as the shrink)

This article argues, from a critical realist perspective, that it would be beneficial to extend thinking on how personal and social education could become more central to students’ learning. We explore how constructive-informed arrangements which emphasize cognitive skills and affective qualities could be realized through experiential approaches to learning. Our theorizing is informed by neo-Aristotelian thinking on the importance of identifying mutually acceptable value commitments which can cultivate practical wisdom as well as generally benefit society. Thereafter, we outline how the (...) recent writings of Tiberius could inform thinking on how, epistemologically and ethically, a first person perspective on learning and personal growth could connect with normative decision making on how to make good life choices. We conclude by briefly highlighting the methodological potential of using outdoor learning environments to help students make informed and wise judgements which show evidence of discernment, deliberation and effective decision making.

Aristotle takes practical wisdom and arts or crafts to be forms of knowledge which, we argue, can usefully be thought of as ‘empiricist’. This empiricism has two key features: knowledge does not rest on grasping unobservable natures or essences; and knowledge does not rest on grasping logical relations that hold among propositions. Instead, knowledge rests on observation, memory, experience and everyday uses of reason. While Aristotle’s conception of theoretical knowledge does require grasping unobservable essences and logical relations that hold among (...) suitable propositions, his conception of practical and productive knowledge avoids such requirements and is consistent with empiricism.

This paper shows the close relationship between morality and emotions, as emotions were defined and understood by classical Greek and Roman philosophers. Particular attention is paid to the nature of anger, and also to the distinction between full-fledged emotions, which depend on rational judgments and which, accordingly, only human beings are capable of experiencing, and what the Stoics called “pre-emotions,” which were common to human beings and other animals.

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.
