No scientist knows the world merely by holding it at arm's length: if we ever managed to build the objectivist wall between the knower and the known, we could know nothing except the wall itself. Science requires an engagement with the world, a live encounter between the knower and the known. That encounter has moments of distance, but it would not be an encounter without moments of intimacy as well. Knowing of any sort is relational, animated by a desire to come into deeper community with what we know.
