In this book, I present the results of an investigation which began with an extended stay at Oxford's Balliol College during the first half of 1995. My visit to Oxford was made possible by a grant from the Spanish Ministerio de Educaci6n y Ciencia. My sincere thanks go to Joseph Raz who served as my supervisor in Oxford. For several points of the present study, conversations with Timothy Endicott in Oxford were also of great help. The book is part of (...) a larger project of investigation, directed by Albert Calsami glia, which is a joint effort of a group of legal philosophers from the Universitat Pom peu Fabra and the Universitat de Girona, and which also receives financial support from the Spanish Ministerio de Educaci6n y Ciencia. An earlier version of the manuscript was presented in June 1996 to the selection committee for a tenured professorship in Legal Philosophy at the Universitat de Girona. The members of the committee were Francisco Laporta, Albert Calsamiglia, Gregorio Peces-Barba, Camilo J. Cela Conde, and Francesca Puigpelat. I am grateful to all of them for their comments, which have been extremely useful in preparing the final ver sion of this book. (shrink)

What does the law demand when it requirescitizens to conform to standards ofreasonableness? I propose and defend theview that the law should demand thatcitizens conform their behavior to someactual conduct in society. I contrast thisidea against what might be called the``empty vessel'' view of reasonableness,where the standard is understood tofunction like an empty vessel in the law,allowing courts to use various norms andmoral judgments to determine what seemsreasonable in the circumstances. Theempty vessel account is the more commonapproach for understanding reasonableness,but (...) it leaves obscure whether and howassessments about appropriate conductconnect with facts about citizens' actualconduct. I argue for a ``binocular'' viewthat focuses our attention on actualpractices and thereby establishes howthese standards provide a stable guide toconduct and support the rule of law. (shrink)

Legal positivism’s multi-faceted insistence on the separability of law and morality includes an insistence on the thoroughly conventional status of legal norms as legal norms. Yet the positivist affirmation of the conventionality of law may initially seem at odds with the mind-independence of the existence and contents and implications of legal norms. Mind-independence, a central aspect of legal objectivity, has been seen by some theorists as incompatible with the mind-dependence of conventions. Such a perception of incompatibility has led some anti-positivist (...) theorists to reject the notion of law’s conventionality, and has led some positivist theorists to query law’s mind-independence. What will be contended here is that both camps are mistaken. (shrink)

In this chapter we address what we call “The-Everybody-Did-It” (TEDI) Syndrome, a symptom for collective negligence. Our main thesis is that the character of scientific communities can be evaluated morally and be found wanting in terms of moral responsibility. Even an epistemically successful scientific community can be morally responsible for consequences that were unforeseen by it and its members and that follow from policy advice given by its individual members. We motivate our account by a critical discussion of a recent (...) proposal by Heather Douglas. We offer three, related criticisms of Douglas’s account. First, she assumes that scientific fields are communicative communities. Second, in a system where the scientific community autonomously sets standards, there is a danger of self-affirming reasoning. Third, she ignores that the character of a scientific community is subject to moral evaluation. We argue that these omissions in Douglas’s theory leave it with no adequate response to TEDI Syndrome. Moreover, we deny that science ought to be characterized by unanimity of belief among its competent practitioners, this leads easily to the vices of close-mindedness and expert-overconfidence. If a scientific community wishes to avoid these vices it should create conditions for an active pluralism when it and its members aspire to the position of rational policy decision-making. (shrink)
