According to Aristotle's Doctrine of the Mean, virtue and a good life involve a mean of feeling and action. This chapter focuses on David Pear's claim that the Doctrine is conceptually incoherent. It argues that there are serious difficulties in understanding what it could be for courage and its feelings to be in a mean. Courage involves plural and incommensurable values, victory and danger, and the respective emotions, confidence and fear––it is difficult to see how these can (...) be resolved into a mean. It is argued that this problem can be solved by seeing how incommensurable value and emotions can fuse into complex wholes of disparate and incommensurable values and emotions, and can thus be assessed as lying or not lying in a mean.

Aristotle's doctrine of the mean is not a counsel to perform mean or moderate actions. It states that excellence of character is a mean state with regard to the having and displaying of emotions. All emotions are morally neutral; character is shown by displaying emotions on the right occasions, Not too often or too rarely, Not too strongly or too weakly, For sufficient and only sufficient reasons, Etc. The difficulties for such a view presented by justice and (...) such bad emotions as envy are discussed. The conclusion is that basically aristotle's theory can resist critical scrutiny. (shrink)

While Aristotle is often lauded, especially by virtue ethicists, for his focus on and insight into virtue, a central aspect of his conception of virtue—the doctrine of the mean—is often derided as false if not indeed absurd. The reason for this disparity in reaction to Aristotle is that the doctrine of the mean has been severely misinterpreted as stating that there are a variety of parameters in which one must achieve a mean. Such a doctrine is false, (...) but it is not Aristotle’s. In this paper, the author gives a more accurate account of the doctrine of the mean than has heretofore been given. According to this account, the doctrine simply states that virtue disposes one to feel one’s passions with an appropriate intensity. The author closes by considering Hursthouse’s famous criticisms of the doctrine of the mean, and he shows that they fail to be reasons for rejecting the doctrine. (shrink)

Aristotle’s doctrine of the mean states that each moral virtue stands opposed to two types of vice: one of excess and one of deficiency, respectively. Critics claim that some virtues—like honesty, fair-mindedness, and patience—are counterexamples to Aristotle’s doctrine. Here, I develop a generalizable strategy to defend the doctrine of the mean against such counterexamples. I argue that not only is the doctrine of the mean defensible, but taking it seriously also allows us to gain substantial insight into (...) particular virtues. Failure to take the doctrine seriously, moreover, exposes us to the risk of mistaking certain vices for virtues. (shrink)

In Zhongyong 中庸 (The Doctrine of the Mean), cheng 诚 (sincerity) is the “Dao of all Daos”, the “virtue of all virtues”, and thus connects the Dao of humans and that of Heaven. The Dao of humans can reveal the sincerity in the Dao of Heaven in two approaches: to contemplate on sincerity and to conduct in sincerity. Meanwhile, sincerity in the Dao of Heaven is unfolded in everything’s seeking for its own nature and destiny, thus the most fundamental (...) approach for the Dao of humans to reveal the sincerity in the Dao of Heaven is for humans to seek for everything’s own nature and destiny.

Aristotle's famous claim that human beings are animals with rationality has a subtle and complicated articulation in his doctrine of the mean. This paper offers textual analysis of Aristotle's discussion of the mean as a resource for coming to terms with the thesis that humans naturally deliberate over the essence of their nature. Unlike other animals who tend to act without deliberation and without mediation, human beings are the animals who are capable of giving an account of themselves. (...) However, this also means that human beings are the animals whose nature it is to give an account. This paper proposes that Aristotle's doctrine of the mean, as it is found in the Nicomachean Ethics, helps to explain this circular, and in some ways puzzling, tension between having a nature and giving an account of one's nature.

Contemporary commentators such as Rosalind Hursthouse misconstrue Aristotle’s doctrine of the ethical mean. They propose a monist account of his moral psychology, explaining each virtue in terms of the presence or absence of a single psychological trait. In contrast, the author argues that Aristotle depicts virtue as a balancing of two opposed psychological inclinations that push and pull in different directions. Each inclination is a positive force in its own right; neither is mere privation. This dualistic account of moral (...) psychology is a more specific application of a recurrent explanatory model one finds elsewhere in Aristotle’s wide-ranging philosophy. In discussing the virtuous mean, moral success can be attributed to the human agent as composite whole or to the indivisible soul. (shrink)

Van Fraassen's Judy Benjamin problem asks how one ought to update one's credence in A upon receiving evidence of the sort ``A may or may not obtain, but B is k times likelier than C'', where {A,B,C} is a partition. Van Fraassen's solution, in the limiting case of increasing k, recommends a posterior converging to the probability of A conditional on A union B, where P is one's prior probability function. Grove and Halpern, and more recently Douven and Romeijn, have (...) argued that one ought to leave credence in A unchanged, i.e. fixed at P(A). We argue that while the former approach is superior, it brings about a Reflection violation due in part to neglect of a ``regression to the mean'' phenomenon, whereby when C is eliminated by random evidence that leaves A and B alive, the ratio P(A):P(B) ought to drift in the direction of 1:1.

The purpose of this paper is to examine the exposition of the doctrine of the mean in the ethical treatises and to determine the role and scope of mesotes within Aristotle's ethical and political theory. The examination of mesotes will reveal the strong connections, for Aristotle, between man, the city, experience, prudence, excellence and eudaimonia. Ultimately, the doctrine of the mean is, in the words of L.W. Rosenfield, an ‘analytical concept’, a component instrumental to Aristotle's theory. Moreover, Aristotle's (...) ethical and political theory is in accordance with the prescriptions of the doctrine of the mean. This is shown through an examination of the thesis, structure and main examples of the Politics, all of which are manifestations of Aristotle's recommendations in his exposition of the doctrine of the mean.

In this article, we illustrate experimentally an important consequence of the stochastic component in choice behaviour which has not been acknowledged so far. Namely, its potential to produce ‘regression to the mean’ (RTM) effects. We employ a novel approach to individual choice under risk, based on repeated multiple-lottery choices (i.e. choices among many lotteries), to show how the high degree of stochastic variability present in individual decisions can distort crucially certain results through RTM effects. We demonstrate the point in (...) the context of a social comparison experiment. (shrink)

Aristotle's doctrine of the mean states that a virtue is the mean state between two vices: a deficient and an excessive one. The Corporate Ethical Virtues Model defines the mean and the corresponding deficient vice for each of its seven virtues. This paper defines for each of these virtues the corresponding excessive vice and explores why organizations characterized by these excessive vices increase the likelihood that their employees will behave unethically. The excessive vices are patronization, pompousness, lavishness, (...) zealotry, overexposure, talkativeness, and oppressiveness. (shrink)

In this paper, we use Saaty's Eigenvector Method and the Power Method as well as Ω=1, 2, ⋯, 9, 1/2, 1/3, ⋯, 1/9} and Ω-={1,2, ⋯,9,1, 1/2, ⋯,1/9} as the sets from which the pairwise comparison judgments are assigned at random to examine the variation in the values determined for the mean random consistency index. By extensive simulation analysis, we found that both methods produce the same values for the mean random consistency random index. Also, we found that (...) the reason for producing two different sets of values is the use of Ω vs. Ω- and not the selection of the Power Method vs. Saaty's Eigenvector Method. (shrink)

On Virtue and Vice is a treatise in ethics. It offers a systematic and historical study of the Doctrine of the Mean. The book argues for a triadic approach to ethical notions (for example, Goodness and two forms of Badness and Justice and two forms of Injustice). The approach of the book is intertwined with a critical study of the relevant thought both of Western thinkers (Pythagoras, Plato, Aristotle, Thomas Aquinas and David Hume) and also of Eastern thinkers (Confucius, (...) Mencius and Chu Hsi). A further aim of the book is to apply the Doctrine to contemporary life. (shrink)

Aristotle's doctrine of the mean is expressed in quantitative terms, but this has been hard for some people to take literally, its more elaborate versions sometimes being described as “extremely silly.” Roughly two books of the Nicomachean Ethics are permeated with talk of character traits which are either deficient or excessive, however, and the aim of this paper is to examine how the doctrine might meet the objections of its critics.

In this paper, I argue that purely quantitative understandings of Aristotle's concept of "the mean" are oversimplified, and I make this argument by analyzing the particular emotion of anger. Anger, I contend, helps to complicate the purely quantitative understanding of the mean, insofar as, I argue, the amount of anger experienced is not the morally salient feature in determining whether or not the anger is virtuous. Rather, anger is one example of an emotion or trait for which other, (...) non-quantitative parameters of the mean are more salient, giving us a more nuanced understanding of what the mean is. Anger is virtuous not when it is in the right measurable degree, but rather when it is directed at the proper target. In this way, the virtue-making property of anger is distinctly qualitative. Examining anger provides insight into the concept of the mean and its role in Aristotle's ethics, and also helps to shed light on contemporary debates about political anger. (shrink)

It is sometimes claimed that Aristotle’s doctrine of the Mean is false or unhelpful: moral virtues are not typically flanked by two opposing vices as he claimed. However, an explicit restatement of Aristotle’s view in terms of sufficiency for an objective reveals that the Mean is more widely applicable than has sometimes been alleged. Understood as a special case of sufficiency, it is essential to many judgments of right and wrong. I consider some objections by Rosalind Hursthouse to (...) Aristotle’s theory and argue that they are based on a misunderstanding. However, there is indeed a tension in Aristotle’s view of goodness, hinted at in his claim that the good is "said in many ways". (shrink)

In the financial markets, there is a well established portfolio optimization model called generalized mean-variance model (or generalized Markowitz model). This model considers that a typical investor, while expecting returns to be high, also expects returns to be as certain as possible. In this paper we introduce a new media optimization system based on the mean-variance model, a novel approach in media planning. After presenting the model in its full generality, we discuss possible advantages of the mean-variance (...) paradigm, such as its flexibility in modeling the optimization problem, its ability of dealing with many media performance indices – satisfying most of the media plan needs – and, most important, the property of diversifying the media portfolios in a natural way, without the need to set up ad hoc constraints to enforce diversification.
