Für moderne Handlungskontexte erweist sich der klassische Verantwortungsbegriff als inadäquat. Ein alternatives Konzept der Verantwortung, das auf der Humeschen Theorie der künstlichen Tugenden basiert, wird entwickelt und an einem einfachen Koordinationsspiel illustriert. Verantwortung wird dabei als das Resultat eines sozialen Zuschreibungsprozesses bestimmt. Menschen, denen Verantwortung zugeschrieben wird, erfüllen eine Funktion als Bezugspunkt sozialer Koordination. Es wird argumentiert, dass eine solche Konzeption gegenüber der klassischen ein feineres und angemesseneres Verständnis des Verhältnisses von kausaler Urheberschaft und Verantwortung vermittelt. Einige Schlussfolgerungen mit Blick auf die Eigenschaften, die Personen in verantwortlichen Positionen haben sollten, werden gezogen. Gefordert sind: Autonomie, Integrität und Kompetenz.

One of the most impressive developments within the field of rational-choice theory is the theory of iterated games. The theory shows that there is a major strategic difference between a single-shot, isolated decision situation and a structurally similar situation that is, however, embedded in a succession of similar situations.

Social norms are based on social standards. The relevant standards corne in two forms. Compliance with social standards of évaluation may be understood as goal-oriented behavior under the constraints of external and internai sanctions. Compliance with norms, which directly refer to specific ways of conduct, may not. Therefore, although norm-guided behavior may be consistent with utility maximizing, no satisfying account of norm compli ance can be given within a Rational Choice framework or any other framework solely based on instrumental rationality

While Rational Choice Theory (RC) may be understood as a theory of choice, which does not necessarily reflect actual deliberative processes, rule-following behavior is definitely based on a certain form of deliberation. This article aims at clarifying the relationship between the two. Being guided by instrumental rules, i.e., rules reducible to the maximization principle, is perfectly consistent with the fundamental behavioral assumptions of RC. But human individuals use other forms of rules in decision making, especially tie-breaking rules and coordination rules. It is argued that within RC no satisfying account of such rule-following behavior can be given. In particular it is impossible to determine suitable preference orderings such that coordinating may be understood as maximizing relative to these orderings. Still, once there is coordination, following a coordination rule may be perfectly consistent with the basic assumptions of RC. So there might be a more complex theory of action that incorporates RC as well as a satisfying theory of rule-guided behavior.

Naturalism, as Binmore understands the term, is characterized by a scientific stance on moral behavior. Binmore claims that a naturalistic account of morality necessarily goes with the conviction “that only hypothetical imperatives make any sense”. In this paper it is argued that this claim is mistaken. First, as Hume’s theory of promising shows, naturalism in the sense of Binmore is very well compatible with acknowledging the importance of categorical imperatives in moral practice. Moreover, second, if Binmore’s own theory of moral practice and its evolution is correct, then the actual moral practice does-and in fact must-incorporate norms, which have the form of a categorical imperative. Categorical imperatives are part of social reality and, therefore, any (normative) moral theory that adequately reflects moral practice must also include categorical imperatives.

Trust is generally held to have three different dimensions or aspects: a behavioral aspect, a cognitive aspect, and an affective aspect. While t here is hardly any disagreement about trusting behavior, there is some disagreement as to which of the two other aspects is more fundamental. After presenting some of the main ideas concerning the concept of trust as used in the analysis of social cooperation. I will argue that affective aspects of trust must be included in any adequate account of the role of trust in social dilemma situations involving multiple equilibria. Cooperation in such situations requires coordination even though information on what another player might do is not available. A trusting person can handle such problems of cooperation by framing the situation in a way that goes beyond cognitive trust and solves what I shall call the problem of normative consent. I will conclude with some remarks ab out the design of institutions that foster trustful cooperation, especially in the context of the Internet.
