Chapter 6 proceeds via a critical review of recent writings about jealousy in philosophy and psychology. Although Aristotle himself did not explore this emotion, it is easily amenable to an Aristotle-style analysis. It turns out, however, that although Aristotelian conceptual and moral arguments about the necessary conceptual features of jealousy qua specific emotion, and the intrinsic value or disvalue of a stable trait of jealousy for eudaimonia, do carry philosophical mileage, they may fail to cut ice with psychologists who tend to focus on jealousy as a broad dimension of temperament. The chapter reveals a disconcerting lack of cross-disciplinary work on jealousy: the sort of work that has moved the discourse on various other emotions forward in recent years. It explains how the best way to ameliorate this lacuna is, precisely, through an Aristotelian analysis, where jealousy is (perhaps counter-intuitively) accorded a place as a potentially virtuous emotion.

Like all transformative revolutions, Britain’s Sixties was an episode of highly influential myth-making. This book delves behind the mythology of inexorable ‘secularization’ to recover, for the first time, the cultural origins of Britain’s moral revolution. In a radical departure from conventional teleologies, it argues that British secularity is a specific cultural invention of the late 1950s and early 1960s, which was introduced most influentially by radical utopian Christians during this most desperate episode of the Cold War. In the 1950s, Britain’s predominantly Christian moral culture had marginalized ‘secular’ moral arguments by arguing that they created societies like the Soviet Union; but the rapid acceptance of ‘secularization’ teleologies in the early 1960s abruptly normalized ‘secular’ attitudes and behaviours, thus prompting the slow social revolution that unfolded during the 1970s, 1980s, and 1990s. By tracing the evolving thought of radical Anglicans—uniquely positioned in the late 1950s and early 1960s as simultaneously moral radicals and authoritative moral insiders—this book reveals crucial and unexpected intellectual links between radical Christianity and the wider invention of Britain’s new secular morality, in areas as diverse as globalism, anti-authoritarianism, sexual liberation, and revolutionary egalitarianism. From the mid-1960s, British secularity began to be developed by a much wider range of groups, and radical Anglicans faded into the cultural background. Yet by disseminating the deeply ideological metanarrative of ‘secularization’ in the early 1960s, and by influentially discussing its implications, they had made crucial contributions to the nature and existence of Britain’s secular revolution.

A long line of work in social psychology has studied variations in people’s susceptibility to persuasion—the extent to which they are willing to modify their opinions on a topic. This body of literature suggests an interesting perspective on theoretical models of opinion formation by interacting parties in a network: in addition to considering interventions that directly modify people’s intrinsic opinions, it is also natural to consider interventions that modify people’s susceptibility to persuasion. In this work, motivated by this fact, we propose an influence optimization problem. Specifically, we adopt a popular model for social opinion dynamics, where each agent has some fixed innate opinion, and a resistance that measures the importance it places on its innate opinion; agents influence one another’s opinions through an iterative process. Under certain conditions, this iterative process converges to some equilibrium opinion vector. For the unbudgeted variant of the problem, the goal is to modify the resistance of any number of agents (within some given range) such that the sum of the equilibrium opinions is minimized; for the budgeted variant, in addition the algorithm is given upfront a restriction on the number of agents whose resistance may be modified. We prove that the objective function is in general non-convex. Hence, formulating the problem as a convex program as in an early version of this work (Abebe et al., KDD’18) might have potential correctness issues. We instead analyze the structure of the objective function, and show that any local optimum is also a global optimum, which is somehow surprising as the objective function might not be convex. Furthermore, we combine the iterative process and the local search paradigm to design very efficient algorithms that can solve the unbudgeted variant of the problem optimally on large-scale graphs containing millions of nodes. Finally, we propose and evaluate experimentally a family of heuristics for the budgeted variant of the problem.
