A number of recent discussions have argued that George Price's equationfor representing evolutionary change is a powerful and illuminatingtool, especially in the context of debates about multiple levels ofselection. Our paper dissects Price's equation in detail, and comparesit to another statistical tool: the calculation and comparison ofaverage fitnesses. The relations between Price's equation and equationsfor evolutionary change using average fitness are closer than issometimes supposed. The two approaches achieve a similar kind ofstatistical summary of one generation of change, and they achieve thisvia a similar loss of information about the underlying fitnessstructure.

This book is a fresh examination of Aristotle's teaching on the relation between reason and moral virtue in the Nicomachean Ethics, taking as its point of departure the oft-noted, but still perhaps not sufficiently appreciated fact, that this treatise is the first half of a two-volume work on political science. As such, it lays the foundation for Aristotelian political science and, in significant ways, for the field of political science altogether. The proper aim of the political community according to Aristotle is to promote the human good; it is the task of the Nicomachean Ethics to elaborate what this good is. It provides Aristotle's fullest answer to the most radical question about justice, the question of why we should be just or moral at all, in its teaching on the essential relation of virtue to happiness.

This book offers a comprehensive account of the major philosophical works on friendship and its relationship to self-love. The book gives central place to Aristotle's searching examination of friendship in the Nicomachean Ethics. Lorraine Pangle argues that the difficulties surrounding this discussion are soon dispelled once one understands the purpose of the Ethics as both a source of practical guidance for life and a profound, theoretical investigation into human nature. The book also provides fresh interpretations of works on friendship by Plato, Cicero, Epicurus, Seneca, Montaigne and Bacon. The author shows how each of these thinkers sheds light on central questions of moral philosophy: is human sociability rooted in neediness or strength? is the best life chiefly solitary, or dedicated to a community with others? Clearly structured and engagingly written, this book will appeal to a broad swathe of readers across philosophy, classics and political science.

The core pluralist thesis about logic, broadly construed, is the claim that two or more logics are correct. In this thesis I discuss a uniquely interesting variant of logical pluralism that I call logical contextualism. Roughly, the logical contextualists’ thought is that, for fixed values p and q, the statement “p entails q” and its cognates such as “q is a logical consequence of p” or “the argument from p to q is logically valid,” are true in some contexts and false in others. After developing a contextualist account of logical pluralism I proceed to examine implications that, if true, logical contextualism would have on discussions about reasonable disagreement among epistemic peers and on discussions about the aim and purpose of argumentation. I show that logical contextualism allows for the possibility of logically-based reasonable disagreements among epistemic peers. In the face of such disagreements there is no obligation to revise one’s belief, nor is there any obligation to degrade the peer status of the agent with whom one stands in disagreement. The possibility of logically-based reasonable disagreements, it will be argued, suggests a reconceptualization of the aims and purpose of argumentation. Most accounts of the purpose of argumentation hold that argumentation’s primary purpose is to achieve rational agreement on a contested issue. Such an agreement is thought to require that at least one of the parties in the argumentation change their beliefs or commitments. However, the existence of logically-based reasonable disagreements, I argue, implies that there are some argumentations that ought not to resolve with agreement. Therefore, rather than understanding argumentation as purely an effort to convince an opponent, or as a means to reach consensus, I claim that argumentation ought to be understood as an effort to gain a better understanding of divergent and perhaps irreconcilable perspectives.

Using a simulated two-party negotiation, we examined how trustworthiness and power balance affected deception. In order to trigger deception, we used an issue that had no value for one of the two parties. We found that high cognitive trust increased deception whereas high affective trust decreased deception. Negotiators who expressed anxiety also used more deception whereas those who expressed optimism also used less deception. The nature of the negotiating relationship (mutuality and level of dependence) interacted with trust and negotiators’ affect to influence levels of deception. Deception was most likely to occur when negotiators reported low trust or expressed negative emotions in the context of nonmutual or low dependence relationships. In these relationships, emotions that signaled certainty were associated with misrepresentation whereas emotions that signaled uncertainty were associated with concealment of information. Negotiators who expressed positive emotions in the context of a nonmutual or high dependence relationship also used less deception. Our results are consistent with a fair trade model in which negotiator increases deception when contextual and interpersonal cues heighten concerns about exploitation and decrease deception when these cues attenuate concerns about exploitation.

Using a simulated, two-party negotiation, we examined how characteristics of the actor, target, and situation affected deception. To trigger deception, we used an issue that had no value for one of the two parties (indifference issue). We found support for an opportunistic betrayal model of deception: deception increased when the other party was perceived as benevolent, trustworthy, and as having integrity. Negotiators’ goals also affected the use of deception. Individualistic, cooperative, and mixed dyads responded differently to information about the other party’s trustworthiness, benevolence, and integrity when deciding to either misrepresent or leverage their indifference issue. Mixed dyads displayed opportunistic betrayal. Negotiators in all-cooperative and all-individualistic dyads used different information in deciding whether to leverage their indifference issues and used the same information (benevolence) differently in deciding whether to misrepresent the value of their indifference issue.

The relation between virtue and knowledge is at the heart of the Socratic view of human excellence, but it also points to a central puzzle of the Platonic dialogues: Can Socrates be serious in his claims that human excellence is constituted by one virtue, that vice is merely the result of ignorance, and that the correct response to crime is therefore not punishment but education? Or are these assertions mere rhetorical ploys by a notoriously complex thinker? Lorraine Smith Pangle traces the argument for the primacy of virtue and the power of knowledge throughout the five dialogues that feature them most prominently—the _Apology, Gorgias, Protagoras, Meno,_ and _Laws_—and reveals the truth at the core of these seemingly strange claims. She argues that Socrates was more aware of the complex causes of human action and of the power of irrational passions than a cursory reading might suggest. Pangle’s perceptive analyses reveal that many of Socrates’s teachings in fact explore the factors that make it difficult for humans to be the rational creatures that he at first seems to claim. Also critical to Pangle’s reading is her emphasis on the political dimensions of the dialogues. Underlying many of the paradoxes, she shows, is a distinction between philosophic and civic virtue that is critical to understanding them. Ultimately, Pangle offers a radically unconventional way of reading Socrates’s views of human excellence: Virtue is not knowledge in any ordinary sense, but true virtue is nothing other than wisdom

Context shapes negotiators’ actions, including their willingness to act unethically. Focusing on negotiators use of deception, we used a simulated two-party negotiation to test how three contextual variables—regulatory focus, power, and trustworthiness—interacted to shift negotiators’ ethical thresholds. We demonstrated that these three variables interact to either inhibit or activate deception, providing support for an interactionist model of ethical decision-making. Three patterns emerged from our analyses. First, low power inhibited and high power activated deception. Second, promotion-focused negotiators favored sins of omission, whereas prevention-focused negotiators favored sins of commission. Third, low cognition-based trust influenced deception when negotiators experience fit between power and regulatory focus, whereas affect-based trust influenced deception when negotiators experience misfit between these structural context variables. We conclude that regulatory focus primes different moral templates: promotion-focused negotiators’ decision to deceive is determined by moral pragmatism, whereas prevention-focused negotiators’ decision to deceive is determined by opportunism. Because each combination of power and regulatory focus was tied to a specific subcomponent of trust, we further conclude that negotiators engage in motivated information search to determine whether they should deceive their opponents.

The most famous man of his age, Benjamin Franklin was an individual of many talents and accomplishments. He invented the wood-burning stove and the lightning rod, he wrote Poor Richard's Almanac and The Way to Wealth, and he traveled the world as a diplomat. But it was in politics that Franklin made his greatest impact. Franklin's political writings are full of fascinating reflections on human nature, on the character of good leadership, and on why government is such a messy and problematic business. Drawing together threads in Franklin's writings, Lorraine Smith Pangle illuminates his thoughts on citizenship, federalism, constitutional government, the role of civil associations, and religious freedom. Of the American Founders, Franklin had an unrivaled understanding of the individual human soul. At the heart of his political vision is a view of democratic citizenship, a rich understanding of the qualities of the heart and mind necessary to support liberty and sustain happiness. This concise introduction reflects Franklin's valuable insight into political issues that continue to be relevant today
