How do criminals solve the problem of trust? What is the social dependence of preferences, and the relationship between causal, rational, and intentional explanations of behavior? In this interdisciplinary anthology, the authors discuss these and related questions in the first of three sections. The essays in the second part explore the consequences of behavior with particular emphasis on the consumption of alcohol, mortality, early onset of drinking, and the evolution of social movements. The third part consists of philosophical essays on objectivity, ethics, and includes a conceptual analysis of 'B.S.'
