 Reasoning, of the sort discussed here, is active or explicit thinking, in which the reasoner, responsibly guided by her assessments of her reasons (Kolodny 2005) and of any applicable requirements of rationality (Broome 2009, 2013), attempts to reach a well-supported answer to a well-defined question (Hieronymi 2013). For Sartre’s student, at least such a question had arisen. Indeed, the question was relatively definite, implying that the student had already engaged in some reflection about the various alternatives available to him – a process that has well been described as an important phase of practical reasoning, one that aptly precedes the effort to make up one’s mind (Harman 1986, 2).
