I use a distinction between single-minded and indifferent choice attitudes, modeled across maximally determinate plans of action, as a basis for interpreting deontic claims – about what ought, ought not, and may be done – as expressing a mode of relation between mind and world that gives voice to the exercise of practical rationality. At the same time, I use maximally determinate possible worlds to model descriptive claims in order to understand them as involving a mode of relation between mind and world that manifests our theoretical rationality. The result is of interest to both linguists looking for a formal treatment of deontic modality that captures the role prescriptive mental states play in our lives, and philosophers interested in substantive questions about action-guiding and representational mental states as exercises of practical and theoretical rationality.

将描述性认知和道义认知建模为思想与世界之间的两种关系模式

我用专一和冷漠的区别选择态度，以最大确定的行动计划为模型，作为解释道义主张的基础——关于应该做什么、不应该做什么和可以做什么——表达一种思想与世界之间的关系模式，为实践理性的行使提供声音. 同时，我使用最大确定的可能世界来对描述性主张进行建模，以便将它们理解为涉及一种体现我们理论理性的思想与世界之间的关系模式。结果对于寻求对道义模态的正式处理以捕捉规定性心理状态在我们生活中所起的作用的语言学家和对作为实践和理论理性练习的行动指导和表征心理状态的实质性问题感兴趣的哲学家都感兴趣。
