Demonstrative logic, the study of demonstration as opposed to persuasion, is the subject of Aristotle's two-volume Analytics. Many examples are geometrical. Demonstration produces knowledge (of the truth of propositions). Persuasion merely produces opinion. Aristotle presented a general truth-and-consequence conception of demonstration meant to apply to all demonstrations. According to him, a demonstration, which normally proves a conclusion not previously known to be true, is an extended argumentation beginning with premises known to be truths and containing a chain of reasoning showing (...) by deductively evident steps that its conclusion is a consequence of its premises. In particular, a demonstration is a deduction whose premises are known to be true. Aristotle's general theory of demonstration required a prior general theory of deduction presented in the Prior Analytics. His general immediate-deduction-chaining conception of deduction was meant to apply to all deductions. According to him, any deduction that is not immediately evident is an extended argumentation that involves a chaining of intermediate immediately evident steps that shows its final conclusion to follow logically from its premises. To illustrate his general theory of deduction, he presented an ingeniously simple and mathematically precise special case traditionally known as the categorical syllogistic. (shrink)

I lay out and examine two sharply conflicting interpretations of Aristotle's claims about nous in the De Anima (DA). On the human separability approach, Aristotle is taken to have identified reasons for thinking that the intellect can, in some way, exist on its own. On the naturalist approach, the soul, including intellectual soul, is inseparable from the body of which it is the form. I discuss how proponents of each approach deal with the key texts from the DA, focusing on (...) four of the most important and interesting topics in this area. Two of these topics concern the activity of understanding (noêsis): first, what does Aristotle mean when he claims that the intellect cannot have a bodily organ and, secondly, what role does Aristotle think phantasmata (“images” or “representations”) play in understanding something? Two of the topics concern DA 3.5, one of the most difficult passages in Aristotle's corpus: first, what is the nature and role of the productive intellect (nous poiêtikos) introduced there and, secondly, what are this chapter's implications for the question of whether the intellect or intellectual soul can exist apart from the body? I conclude by identifying areas where further research is necessary. (shrink)

This paper argues against the view favored by many contemporary scholars that corrective justice in the Nicomachean Ethics is essentially compensatory and in favor of a bifunctional account according to which corrective justice aims at equalizing inequalities of both goods and evils resulting from various interactions between persons. Not only does the account defended in this paper better explain the broad array of examples Aristotle provides than does the standard interpretation, it also better fits Aristotle’s general definition of what is (...) just. In the last section, the paper argues, again against the standard interpretation, that proportional reciprocity, the kind of justice discussed in Nicomachean Ethics V.5, has two forms and is closely linked to corrective justice. Although corrective justice and proportional reciprocity are conceptually distinct and do different work in Aristotle’s political philosophy, instances of proportional reciprocity are instantiated by instances of corrective justice. This linkage, the paper concludes, helps to explain why Aristotle would assign corrective justice such a prominent place in his theory of justice. (shrink)

Accounts of ontic explanation have often been devised so as to provide an understanding of mechanism and of causation. Ontic accounts differ quite radically in their ontologies, and one of the latest additions to this tradition proposed by Peter Machamer, Lindley Darden and Carl Craver reintroduces the concept of activity. In this paper I ask whether this influential and activity-based account of mechanisms is viable as an ontic account. I focus on polygenic scenarios—scenarios in which the causal truths depend on (...) more than one cause. The importance of polygenic causation was noticed early on by Mill (1893). It has since been shown to be a problem for both causal-law approaches to causation (Cartwright 1983) and accounts of causation cast in terms of capacities (Dupré 1993; Glennan 1997, pp. 605-626). However, whereas mechanistic accounts seem to be attractive precisely because they promise to handle complicated causal scenarios, polygenic causation needs to be examined more thoroughly in the emerging literature on activity-based mechanisms. The activity-based account proposed in Machamer et al. (2000, pp. 1-25) is problematic as an ontic account, I will argue. It seems necessary to ask, of any ontic account, how well it performs in causal situations where—at the explanandum level of mechanism—no activity occurs. In addition, it should be asked how well the activity-based account performs in situations where there are too few activities around to match the polygenic causal origin of the explanandum. The first situation presents an explanandum-problem and the second situation presents an explanans-problem—I will argue—both of which threaten activity-based frameworks. (shrink)

I argue that Aristotle's approach to the proper type of acquisition, use-value, want, and accumulation/storage of wealth is oriented less to excluding commercial activity, such as that of Aristotle's Athens, than to forestalling misordered concupiscence – the taking of an inherendy limited good for the unlimited, or highest, good. That is, his moral aversion to taking a means for an end lies behind his rendering of the sort of wealth that is natural. By stressing the limited nature of natural wealth, (...) Aristode distinguishes such wealth qua limited from an artificial unlimited desire for profit in order to drive home his point that wealth ought not be taken as an objective good (i. e., good in itself).

_ Source: _Volume 9, Issue 2, pp 129 - 145 The aim of this paper is to highlight the importance of ἕξις in Plotinus’ virtue ethics. It is argued that since ἕξις signifies a quality of being in a permanent state of possession and virtue is defined as an ἕξις that intellectualizes the soul, therefore, it is suggested that virtue is an active ἕξις of the soul directed higher to the intelligible world in permanent contemplation of the Forms.

In one of the unpublished parts of his manuscript titled the Spicilegia, Arthur Schopenhauer presents an uncharacteristically sympathetic reading of an Aristotelian text. The text in question, De anima III. 5, happens to include the only occurrence of arguably the most controversial idea in Aristotle, namely the distinction between active and passive nous. Schopenhauer interprets these two notions as corresponding to his own notions of the ?will? and the ?intellect? or ?subject of knowledge?, respectively. The result is a unique interpretation, (...) according to which Aristotle's active nous is in fact non-intellectual: it is devoid of any interaction with intelligible objects, and hence lacks any intellectual activity. I show that this interpretation, though counterintuitive, is tenable, and that it may contribute to our understanding of Aristotle even if we do not adopt Schopenhauer's metaphysics. (shrink)

It is a central tenet of ethical intuitionism as defended by W. D. Ross and others that moral theory should reflect the convictions of mature moral agents. Hence, intuitionism is plausible to the extent that it corresponds to our well-considered moral judgments. After arguing for this claim, I discuss whether intuitionists offer an empirically adequate account of our moral obligations. I do this by applying recent empirical research by John Mikhail that is based on the idea of a universal moral (...) grammar to a number of claims implicit in W. D. Ross’s normative theory. I argue that the results at least partly vindicate intuitionism. (shrink)

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.

The author distinguishes between scientific and prudential reason (practical wisdom) in Aristotle with reference to the nature of the principles assumed as premises, and to the method of inference. In the history of thought these two models of reason are elieved not only to be proper to science and, respectively, ethics, but also, at times, to be the scientific model proper to ethics (for example, in natural law doctrines) and the prudential model proper to science. Mixed models are also given (...) in the history of thought: scientific‐prudential (for example, in Thomas Aquinas) and prudential‐scientific. Furthermore, some aspects of the relationship between authority and reason are examined. (shrink)

This paper tests the following hypothesis: that the prime matter of classical Aristotelian-Scholastic metaphysics is numerically identical to energy. Is P=E? After outlining the classical Aristotelian concept of prime matter, I provide the master argument for it based on the phenomenon of substantial change. I then outline what we know about energy as a scientific concept, including its role and application in some key fields. Next, I consider the arguments in favour of prime matter being identical to energy, followed by (...) the arguments against. The method used is that of ontological profile comparison: does the profile of prime matter match, in key features, that of energy? An affirmative answer, that P=E, would be a momentous discovery: it would show that one of the most neglected and derided ideas of pre-modern metaphysics – a contributor to its downfall in the wake of the Scientific Revolution – was right all along. From a negative answer we would still learn much about the interaction of science and metaphysics. It turns out, however, given what we currently know, that the answer is not quite as simple as one might hope. (shrink)

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

This paper presents a reading of Metaphysics Z.10–11 according to which both chapters outline two main definienda: forms and material substances or compounds, each of which is governed by its own peculiar constraints. Forms include formal parts alone; furthermore, they are the main definable items and enjoy the strictest possible unity. However, this does not preclude Aristotle from upgrading material compounds to the status of definable items in their own right. Z.10 explains this contention by making the compound’s sensible functional (...) matter dependent on its form. This dependence affords the resulting compound an unusually tight form-matter relationship, strong enough to ensure its definability, despite falling short of the highest kind of unity that only forms display.

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

Books M and N of Aristotle's Metaphysics receive relatively little careful attention. Even scholars who give detailed analyses of the arguments in M-N dismiss many of them as hopelessly flawed and biased, and find Aristotle's critique to be riddled with mistakes and question-begging. This assessment of the quality of Aristotle's critique of his predecessors (and of the Platonists in particular), is widespread. The series of arguments in M 2 (1077a14-b11) that targets separate mathematical objects is the subject of particularly strong (...) criticism by Annas and Ross. Two related arguments in this series (1077a14-20 and 1077a24-31) will serve as cases in point. The principal charges made against these arguments (that Aristotle misunderstands or misrepresents his opponents' views, and that he engages in question-begging because he presupposes his own metaphysical views) are frequently made against Aristotle's critique of Platonist positions more generally. If, as I argue, these charges are false for our two test case arguments, then there is good reason to think that they might also be false when they are leveled against the other arguments in this M 2 series. And, although presenting an argument for this is beyond the scope of this paper, this suggests that these two charges are more often than not false when applied to Aristotle's critique of Platonist mathematical views in M-N and beyond.

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