Flexibility is one of the hallmarks of human problem‐solving. In everyday life, people adapt to changes in common tasks with little to no additional training. Much of the existing work on flexibility in human problem‐solving has focused on how people adapt to tasks in new domains by drawing on solutions from previously learned domains. In real‐world tasks, however, humans must generalize across a wide range of within‐domain variation. In this work we argue that representational abstraction plays an important role in (...) such within‐domain generalization. We then explore the nature of this representational abstraction in realistically complex tasks like video games by demonstrating how the same model‐based planning framework produces distinct generalization behaviors under different classes of task representation. Finally, we compare the behavior of agents with these task representations to humans in a series of novel grid‐based video game tasks. Our results provide evidence for the claim that within‐domain flexibility in humans derives from task representations composed of propositional rules written in terms of objects and relational categories.

We routinely observe others’ choices and use them to guide our own. Whose choices influence us more, and why? Prior work has focused on the effect of perceived similarity between two individuals, such as the degree of overlap in past choices or explicitly recognizable group affiliations. In the real world, however, any dyadic relationship is part of a more complex social structure involving multiple social groups that are not directly observable. Here we suggest that human learners go beyond dyadic similarities (...) in choice behaviors or explicit group memberships; they infer the structure of social influence by grouping individuals based on choices, and they use these groups to decide whose choices to follow. We propose a computational model that formalizes this idea, and we test the model predictions in a series of behavioral experiments. In Experiment 1, we reproduce a well-established finding that people's choices are more likely to be influenced by someone whose past choices are more similar to their own past choices, as predicted by our model as well as dyadic similarity models. In Experiments 2–5, we test a set of unique predictions of our model by looking at cases where the degree of choice overlap between individuals is equated, but their choices indicate a latent group structure. We then apply our model to prior empirical results on infants’ understanding of others’ preferences, presenting an alternative account of developmental changes. Finally, we discuss how our model relates to classical findings in the social influence literature and the theoretical implications of our model. Taken together, our findings demonstrate that structure learning is a powerful framework for explaining the influence of social information on decision making in a variety of contexts. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Beauty, Transcendence, and the Inclusive Hierarchy of Creation1Thomas Joseph White, O.P.Interpreters of Thomas Aquinas have long argued about whether he holds that beauty is a “transcendental,” a feature of reality coextensive with all that exists, like unity, goodness, and truthfulness.2 In the first part of this article, I will argue that Aquinas can [End Page 1215] be read to affirm in an implicit way that beauty is a (...) transcendental. In the second part, I will consider what it might mean from a Thomistic point of view to speak of a transcendent divine beauty, given Aquinas’s metaphysical commitments, particularly with respect to his doctrine of divine simplicity. In the final part, I will treat the question of how the beauty of the creation both manifests and conceals divine beauty.Beauty as a Transcendental Feature of RealityAquinas does not list beauty as a transcendental term in texts on transcendental notions. Perhaps, then, one should simply exclude it from a responsible account of his teaching on this subject. However, at least two well-known texts should give us reason to pause before reaching such a conclusion. One is found in his Commentary on Dionysius’ Divine Names, chapter 4, lectio 5. The other is in his discussion of the beauty of the eternal Son of God in a discussion of the Holy Trinity in the Summa theologiae I, q. 39, a. 8.In the first of these texts, Aquinas is commenting on Dionysius. The extended text is analytically dense. Aquinas is discussing ways in which one might say that God is beautiful and in what ways one might not say so. I will return to his topic below. Here, however, it is pertinent to consider Aquinas’s discussion of the presence of beauty in all that exists. He makes six main points.3 First, all beauty comes [End Page 1216] from God insofar as God is the cause of all that exists. Second, he gives a first definition of beauty: beauty can be defined ontologically as the splendor (claritas) that results from form; everything has a formal determination of some kind insofar as it has existence (esse); therefore, insofar as anything exists (and has some formal ontological content) it has some degree of beauty. Third, the splendor of the form in created things is a participation in the divine splendor from which it originates. The divine nature is the transcendent exemplar of beauty in diverse finite created realities. Fourth, then (and perhaps most importantly), “ex divina pulchritudine esse omnium derivatur”: literally, the existence of everything originates from divine beauty. Fifth, a second definition of beauty is considered: beauty can be defined ontologically as a property of being that emerges from proportion or harmony (consonantia). For example, authentic relationships of personal friendship imply spiritual harmony or concord and are beautiful and noble in this respect. Sixth, then, the concord or beautiful harmonies we find in the created order are expressive of the wisdom of God, who is the author of creation.Evidently, if the existence of everything derives from divine beauty, and if everything that has existence is in some way beautiful by virtue of its intrinsic form, then it would seem to follow logically that beauty, for Aquinas, is a characteristic of being that is coextensive with all that exists. We see a similar idea expressed in the aforementioned passage of ST. Here, however, Aquinas gives a more synthetic definition of beauty in things that combines both the definitions found in our previous discussion, claritas and proportio, but it also adds a third, integritas: ontological integrity or wholeness.Species or beauty has a likeness to the property of the Son. For beauty includes three conditions, “integrity” or “perfection,” [End Page 1217] since those things which are impaired are by the very fact ugly; due “proportion” or “harmony”; and lastly, “brightness” or “clarity,” whence things are called beautiful which have a bright color.4The implication of this point of view is readily apparent. God is essentially beautiful, and God has created all that exists in light of the eternal Word and Wisdom of God, who is the Son. Consequently, all that exists and that... (shrink)

For courses in Business Ethics A fresh approach to the assumptions that underlie business practices Two recent events — the 2008 economic meltdown and the ongoing concentration of the nation's wealth in the hands of a very small percentage of the population — have led many people to question a number of basic assumptions about business, corporations, and the workings of contemporary free-market capitalism in a global economy. Written as a dialogue between Socrates and a hypothetical contemporary CEO,Socrates Comes to (...) Wall Street leads students to think critically about perspectives and practices that are taken as “givens” in most American business schools and corporations. Employing this original and provocative approach, author Thomas White seeks to encourage the next generation of business leaders to be more astute about the implications of their actions, and to act more prudently and more fairly than we have seen in the recent past.

Known as 'Darwin's Bulldog', the biologist Thomas Henry Huxley was a tireless supporter of the evolutionary theories of his friend Charles Darwin. Huxley also made his own significant scientific contributions, and he was influential in the development of science education despite having had only two years of formal schooling. He established his scientific reputation through experiments on aquatic life carried out during a voyage to Australia while working as an assistant surgeon in the Royal Navy; ultimately he became President (...) of the Royal Society. Throughout his life Huxley struggled with issues of faith, and he coined the term 'agnostic' to describe his beliefs. This nine-volume collection of Huxley's essays, which he edited and published in 1893–4, demonstrates the wide range of his intellectual interests. Volume 2 examines the criticism and controversy surrounding Darwin's work, and the implications of his ideas on biological science. (shrink)

This paper reviews the concept of human dignity as it has evolved in recent decisions by the United States Supreme Court, and the paper then sketches a “rights based” theory of human dignity. Among the principles of human dignity is a principle of compensation for mistakes in the treatment of any person. A broad concept of mistake is outlined, and, in terms of this concept and the principles of dignity, the practice of capital punishment is examined. An argument by Jeffrie (...) Murphy against capital punishment is stated and criticized and a stronger argument against capital punishment is presented. (shrink)

The paper maintains that Frege's quantification of sentence positions motivates his identification of sentences as proper names of truth-values; that this identification is fully compatible with the Context Principle; that the relation of a thought to its truth-value is the primary case of the relation of sense to meaning. The paper offers a reconstruction of Frege's defense of in pp. 33-5 of “On Sense and Meaning”O artigo sustenta que a quantificação Fregeana sobre posições de sentença motiva sua identificação de sentenças (...) como nomes próprios de valores de verdade; que esta identificação é inteiramente compatível com o Princípio do Contexto; que a relação de um pensamento com o seu valor de verdade é o caso primário da relação do sentido para com o significado.

This book introduces readers to analytical interpretation of seminal writings and thinkers in the history of political thought, including Socrates, Plato, Aristotle, the Bible, Thomas Aquinas, Machiavelli, Bacon, Hobbes, Locke, Montesquieu, Rousseau, Tocqueville, Marx, and Nietzsche. Chronologically arranged, each chapter in the book is devoted to the work of a single thinker. The selected texts together engage with 2000 years of debate on fundamental questions including: what is the purpose of political life? What is justice? What is a right? (...) Do human beings have rights? What kinds of human virtues are there and which regimes best promote them? The difficulty of accessing the texts included in this volume is the result not only of their subtlety but also of the dramatic change in everyday life. The authors shed light on the texts' vocabulary and complexities of thought and help students understand and weigh the various interpretations of each philosopher's thought. (shrink)

This paper examines three possible justifications for original ACMG recommendations to return incidental findings from whole exome or genome sequencing independent of patient preferences. The first two potential justifications, based on a patient's authentic values, then on harms to others, are founding lacking as a basis of justification for these recommendations. The third, grounded in analogous professional practices, might serve as a potential justification if several controversies can be avoided. However, given the nature of these controversies and the need to (...) instill public trust in this newly emerging science, the paper finds that updated ACMG recommendations that recognize opt-out rights on behalf of patients is the most prudent, and justifiable, approach.

Proceedings of a Conference on experience in Medieval natural philosophy.

We use payroll data from a Big 4 accounting firm to examine the starting wage differentials for H-1B visa holders. Prior research in other industries has found mixed results, but primarily relies on surveyed salary data. We observe that relative to U.S. citizen new hires—matched on office, position, and time of hire—newly hired accountants with H-1B visas receive starting salaries that are lower by approximately 10%. This finding calls into question the efficacy of regulatory mandates thought to prevent H-1B visa (...) holders from being paid less than U.S. citizens in similar roles. In further tests, we find evidence that the hiring of H-1B visa holders has no or some small positive effect on the wages of peer U.S. citizen new hires (weakly indicative of complementarities or synergies), but no evidence of H-1B hiring driving down the wages for U.S. citizen peer new hires.
