Different researchers from psychology and neuroscience state that navigation involves the manipulation of cognitive maps and graphs. In this paper, I will argue that navigating – specifically, journey planning – can be conceived as a process of practical reasoning. First, I will argue that journey planning constitutes a case of means-end reasoning involving inferences with cartographic representations. Then, I will argue that the output of journey planning functions as an instrumental belief in means-end reasoning. More specifically, journey planning can deliver (...) an instrumental rule that plays a normative role in spatial cognition. This approach motivates a pluralist conception of practical reasoning, stating that inferences might run through different representational formats and processes. (shrink)
