A conception we use to pose a problem or question about something, or to propose a solution, answer or account, or to actually respond practically may be common to across the questioning, asserting or doing — or we might find the conception only works in one or another of these activities.

In the former case, where a single conception guides our asking, asserting and doing, the conception can be said to belong to a praxis.

In the latter case, we will stumble over separations between theory and practice, and conceptions are confined to mere practice or mere theory. Most philosophy pays nearly no attention to practice apart from being able to ask and assert in philosophical contexts, and this is why very few people see any value in philosophy.

I value philosophy if — and only if — the philosophy is an integral component of some praxis, which is the case for much of Pragmatism and Existentialism.

Maybe I can use this insight to pry some books out of my library.
