What Is This Knowledge That We Seek to “Exchange”?

S urely it is time to problematize and critically question what knowledge is. How does it differ from data, information, evidence, or experience? Is it explicit or tacit, individual or collective, generic or specific, context free or context bound, value neutral or value laden? To what extent do these dualities, well rehearsed in the literature, adequately capture what we know and do not know about knowledge and its exchange? Let me summarize what I think that Contandriopoulos and colleagues are saying before returning to consider how well they have answered (or sidestepped) these ontological questions.
