Practical knowledge

Practical knowledge is a peculiar concept. On the one hand, I find philosophical attempts to articulate it to be almost always incomprehensible. On the other hand, when I think about the relevant ordinary cases, I’m convinced that it demarcates a special form of knowledge that is distinct from theoretical knowledge. Let me explain.

First, Anscombe famously complains that “modern philosophers” (a broad brush?) have “blankly misunderstood” what “ancient and medieval philosophers” (speaking of broad brushes!) meant by practical knowledge (Anscombe 1958, sec. 32). But it’s notoriously difficult to get a grip on her positive proposal:

Practical knowledge is 'the cause of what it understands', unlike 'speculative' knowledge, which 'is derived from the object known'. (Anscombe 1958, sec. 48)

On this influential account then, practical knowledge is a way of knowing where the known fact is in somehow caused by the state of knowing that fact. But many have worried that this notion is “causally perverse” and “epistemically mysterious” (Velleman 2007, 103; c.f. Schwenkler 2015). I can know that there is ice-cream in the fridge only if that’s the case; but my knowledge of that fact does not miraculously bring about an ice-cream into the world. How can knowing p make it the case that p?

Now, I am among those who are convinced that Anscombe is on the right tracks here. And this is not (only) because of a nostalgia for medieval scholasticism. Although practical knowledge seems to resist philosophical clarification, I think it gestures towards an idea that is rather intuitive.
