Much has been written on whether practical knowledge (knowledge‐how) reduces to propositional knowledge (knowledge‐that). Less attention has been paid to what we call deliberative knowledge (knowledge‐to), i.e., knowledge ascriptions embedding other infinitival questions, like where to meet, when to leave, and what to bring. We offer an analysis of knowledge‐to and argue on its basis that, regardless of whether knowledge‐how reduces to knowledge‐that, no such reduction of knowledge‐to is forthcoming. Knowledge‐to, unlike knowledge‐that and knowledge‐how, requires the agent to have formed certain conditional intentions. We discuss the philosophical implications for knowledge‐how, deliberative questions, and virtue.

知道该做什么

关于实践知识（知识-如何）是否还原为命题知识（知识-知识）已经有很多文章。人们很少关注我们所谓的深思熟虑的知识（knowledge-to），即嵌入其他不定式问题的知识归属，例如在哪见面,什么时候离开， 和需要带些什么。我们对knowledge-to进行了分析，并在此基础上论证，无论knowledge-how是否还原为knowledge-that，都不会出现这种knowledge-to的还原。与“知识”和“如何知识”不同，“知识”要求主体形成一定的条件意图。我们讨论知识、深思熟虑的问题和美德的哲学含义。
