Generic sentences (e.g., bare plural sentences such as “dogs have four legs” and “mosquitoes carry malaria”) are used to talk about kinds of things. Three experiments investigated the conceptual foundations of generics as well as claims within the formal semantic approaches to generics concerning the roles of prevalence, cue validity and normalcy in licensing generics. Two classes of generic sentences that pose challenges to both the conceptually based and formal semantic approaches to generics were investigated. Striking property generics (e.g. “sharks (...) bite swimmers”) are true even though only a tiny minority of instances have the property and thus pose obvious problems for quantificational approaches, and they also do not seem to characterize kinds in terms of the principled or statistical connections investigated in previous research ( Prasada and Dillingham, 2006 ; Prasada and Dillingham, 2009). The second class — minority characteristic generics (e.g. “ducks lay eggs”) — also poses serious problems for quantificational accounts, and appears to involve principled connections even though fewer than half of its instances have the relevant property. The experiments revealed three principal discoveries: first, striking generics involve neither principled nor statistical connections. Instead, they involve a causal connection between a kind and a property. Second, minority characteristic generics exhibit the characteristics of principled connections, which suggests that principled connections license the expectation that most instances will have the property, but do not require it. Finally, the experiments also provided evidence that prevalence and the acceptability of generics may be dissociated and provided data that are problematic for normalcy approaches to generics, and for the idea that cue validity licenses low prevalence generics. As such, the studies provided evidence in favor of a conceptually based approach to the semantics of generics ( Leslie, 2007 ; Leslie, 2008; see also Carlson, 2009). (shrink)

Nominal concepts represent things as tokens of types. Recent research suggests that we represent principled connections between the type of thing something is (e.g., DOG) and some of its properties (k‐properties; e.g., having four legs for dogs) but not other properties (t‐properties; e.g., being brown for dogs). Principled connections differ from logical, statistical, and causal connections. Principled connections license (i) the expectation that tokens of the type will generally possess their k‐properties, (ii) formal explanations (i.e., explanation of the presence of (...) k‐properties in tokens of a type by reference to the type of thing it is), and (iii) normative expectations concerning the presence of k‐properties in tokens of the type. The present paper investigates the hypothesis that representing principled connections requires representing properties as aspects of being the relevant kind of thing (Aspect Hypothesis). Experiment 1 provides a direct test of the Aspect Hypothesis. Experiments 2 and 3 provide indirect tests of the Aspect Hypothesis. All three experiments provide support for the Aspect Hypothesis. Experiment 4 investigates a prediction of the Aspect Hypothesis concerning the manner in which formal explanations are licensed by principled connections. Finally, Experiment 5 investigates a prediction of the Aspect Hypothesis concerning the nature of the normative expectations licensed by principled connections. Together these results provide strong evidence for the idea that representing principled connections involves representing a property as being an aspect of being a given kind of thing. The results also help clarify the manner in which formal explanation differs from other modes of explanation. Finally, the results of the experiments are used to motivate a proposal concerning the formal structure of the conceptual representations implicated by principled connections. This structure provides a domain‐general way of structuring our concepts and embodies the perspective we take when we think and talk of things as being instances of a kind. (shrink)

This volume explores Plato and Aristotle's theories about good things, goodness, and the best life for human beings, and draws comparisons between ancient and modern theories of good and justice.

We investigate the hypothesis that our conceptual systems provide two formally distinct ways of representing categories by investigating the manner in which lexical nominals (e.g., tree, picnic table) and phrasal nominals (e.g., black bird, birds that like rice) are interpreted. Four experiments found that lexical nominals may be mapped onto kind representations, whereas phrasal nominals map onto class representations but not kind representations. Experiment 1 found that phrasal nominals, unlike lexical nominals, are mapped onto categories whose members need not be (...) of a single kind. Experiments 2 and 3 found that categories named by lexical nominals enter into both class inclusion and kind hierarchies and thus support both class inclusion (is a) and kind specification (kind of) relations, whereas phrasal nominals map onto class representations which support only class inclusion relations. Experiment 4 showed that the two types of nominals represent hierarchical relations in different ways. Phrasal nominals (e.g., white bear) are mapped onto classes that have criteria of membership in addition to those specified by the class picked out by the head noun of the phrase (e.g., bear). In contrast, lexical nominals (e.g., polar bear) specify one way to meet the criteria specified by the more general kind concept (e.g., bear). Implications for the language–conceptual system interface, representation of hierarchical relations, lexicalization, and theories of conceptual combination are discussed. (shrink)

What is love? Why do we idealize those whom we love? How do we choose whom to love? Are some kinds of love better than others? Each age returns to these questions with renewed perplexity. Gerasimos Santas examinees the two greatest theoretical architectures of love, side by side. It provides a thorough critical description and comparison of these theories, allowing a sophisticated dialogue to emerge between the two thinkers. In the first half of the book Professor Santas reconstructs and explains (...) Plato's theories of eros and philia: erotic love, familial love and friendship. He attempt to show that Plato's was a unified theory in which erotic love has a special connecion with creativity and beauty. He then discusses Freud's notion of love as distinct from, though based on, his general theory of sexuality. He discusses in detail Freud's explanations, before and after narcissism, of idealization and choice of beloved. Freud too, it emerges, had a unified theory of love: all love has its origins in the libidinal instincts of infancy and childhood. The book concludes by showing that, despite Freud's claim that his theory of love is 'Platonic', the two theories are instructively different. (shrink)

Five experiments provide evidence for a class of ‘dual character concepts.’ Dual character concepts characterize their members in terms of both (a) a set of concrete features and (b) the abstract values that these features serve to realize. As such, these concepts provide two bases for evaluating category members and two different criteria for category membership. Experiment 1 provides support for the notion that dual character concepts have two bases for evaluation. Experiments 2-4 explore the claim that dual character concepts (...) have two different criteria for category membership. The results show that when an object possesses the appropriate concrete features, but does not fulfill the appropriate abstract value, it is judged to be a category member in one sense but not in another. Finally, Experiment 5 uses the theory developed here to construct artificial dual character concepts and examines whether participants react to these artificial concepts in the same way as naturally occurring dual character concepts. The present studies serve to define the nature of dual character concepts and distinguish them from other types of concepts (e.g., natural kind concepts), which share some, but not all of the properties of dual character concepts. More broadly, these phenomena suggest a normative dimension in everyday conceptual representation. (shrink)

Research on the representation of generic knowledge suggests that inherent properties can have either a principled or a causal connection to a kind. The type of connection determines whether the outcome of the storytelling process will include intuitions of inevitability and a normative dimension and whether it will ground causal explanations.

Plato's antidemocratic theory of social justice is instructive once we distinguish between the abstract parts of his theory and the empirical or other assumptions he uses in applying that theory. His application may have contained empirical mistakes, and it may have been burdened too much with a prolific metaphysics and a demanding epistemology. An attempt is made to look at his theory of social justice in imaginary isolation from empirical mistakes and from his metaphysics and epistemology. It is then argued (...) that some of Plato's proposals and criticisms of democracy are well worth our attention, especially in the case of governing. His attempt to separate ruling and wealth and to establish economic floors and ceilings for his ideal city seems especially instructive in view of problems in these areas that modern democracies have experienced. Isolating his theory of social justice from his epistemology and metaphysics may be more problematic. Still, Plato's insistence that superior wisdom is the central virtue of rulers is instructive, and in this respect some modern defenders of democratic justice, such as J. S. Mill and John Rawls, have leaned some in Plato's direction. Finally, Plato's criticism of democratic free choice of occupation is less persuasive.

This book provides specific answers to questions and concerns related to sin, confession, self-worth, sexuality, prayer, God's forgiveness, thoughts, dreams, fantasies, and other issues. It offers words of encouragement and helpful suggestions (...) to those who suffer from this affliction and for those who counsel them. (shrink)

The main conversation in the Laches is about courage. But the main conversation does not begin till the middle of the dialogue. In the first half Plato sets the stage for the serious discussion that follows. Two elder men of Athens, Lysimachus and Melesias, are worried about the education of their sons. They themselves are the sons of two eminent Athenians, Thucydides and Aristides, and they feel that while their famous fathers conducted the affairs of the city with great energy (...) they did not show a similar concern for the education of their sons. They feel inferior to their fathers and do not want their own sons to feel the same way. They wish their sons to be like their own fathers, not like themselves--active citizens, not idle aristocrats. In this frame of mind, they are most anxious for expert and sound advice about their sons' education. Someone recommended to them for this purpose a new military exercise, fighting in armor. They invited two eminent generals of the day, Nicias and Laches, to see with them an exhibition of fighting in armor, and now they eagerly seek the generals' opinion about the worth of it. (shrink)
