 What is the relation between knowledge-how and skill? For many tasks at least, it is intuitive that one cannot be skilled at it without knowing how to perform it. At first, it also seems as if knowledge-how entails skill: one does not really know how to swim if one does not have the skill to swim; and one cannot know how to tell apart birds without the skills of a bird watcher. One might object to the sufficiency of knowledge-how for skill on the grounds that it is natural to say things such as “John may know how to make risotto, but I would not say he is skilled at it”. However, knowing how to make risotto sufficiently well (relative to contextually determined standards) might entail being skilled at it (relative to the same standards) (Cath 2020).
