Why do utterances of counterfactual conditionals typically, but not universally, convey the message that their antecedents are false? I demonstrate that two common theoretical commitments–commitment to the existence of scalar implicature and of informative presupposition—can be supplemented with an independently motivated theory of the presuppositions of competing conditional alternatives to jointly predict this information when and only when it appears. The view works best if indicative and counterfactual conditionals have a closely related semantics, so I conclude by undermining two familiar arguments for a nonunified semantics of indicative and counterfactual conditionals. 相似文献

Enormous harms, such as climate change, often occur as the result of large numbers of individuals acting separately. In collective action problems, an individual has so little chance of making a difference to these harms that changing their behavior has insignificant expected utility. Even so, it is intuitive that individuals in many collective action problems should not be parts of groups that cause these great harms. This paper gives an account of when we do and do not have obligations to change our behavior in collective action problems. It also addresses a question insufficiently explored in the literature on this topic: when obligations arising out of collective action problems conflict with other obligations, what should we do? The paper explains how to adjudicate conflicts involving two collective action problems and conflicts involving collective action problems and other sorts of obligations. 相似文献

Criminological examination of substance use is common in the extant literature; however, little research has examined heroin use among adolescents. Recent trends in drug use indicate a rise of heroin among adolescents indicating a need to provide theoretical explanations of this phenomenon. This study examines the efficacy of social learning theory and social bond theory to explain heroin use. The study uses a nationally representative sample of adolescents from the Monitoring the Future Survey (N = 2,465). The results support the central arguments from social structure social learning theory. First, the results show that social structure components have links with heroin use. Second, the results show that social learning theory mediates the effect of social structure measures on heroin use. The results are discussed. 相似文献

AbstractIn Phaedo, Plato shows the grace of a true courage which can affirm life even in death. Socrates’ courage is not that of the martyr, grounded on a belief in divine reward; his is the courage of the philosopher who knows that he does not know. In his self-reflexive striving to be a person who strives for wisdom, Socrates dissipates the fear of death by dissolving the presumption on which this fear is based, and reframing death as an opportunity for knowledge. Socrates’ courage is therefore founded on an epistemic hope that is embodied in the very activity of philosophy. 相似文献

Community organizers and activists draw on multiple traditions of community building and collective action in attempts to galvanize change. The diversity of perspectives on social change processes indicates corresponding differences in perspectives on systems and what is required to change them. Twenty‐two in‐depth interviews with community organizers and activists in the Midwestern USA were conducted to identify differences in perspectives on systems change efforts. Four models used by organizers were identified: action/issue‐centric, identity‐centric, relationship‐centric, and organizing‐development. Strategies for recruitment, issue selection, leadership determination, and action were compared across models. Analyses revealed that some models might be better suited to action on certain issues (e.g. identity‐centric models when organizing around homelessness), whereas others may have advantages for use in certain settings (e.g. relationship‐centric models in congregations). These findings suggest that practitioners and scholars should pay close attention to contextual factors and focal issues when determining strategies for creating systems change.
