In most contexts, I have become quite convinced that meaning and intelligibility are inseparable from actual articulation, and that knowledge is the ability to explain. However, there are people who frequently turn out to have insight and understanding that goes well beyond what they can articulate. Perhaps the apparent difficulty here could be explained away by noting that actual articulation need not be immediately actual. But without by any means giving up on the linguistic turn, I suspect the neuroscience people may ultimately have something to offer us in this area.
I think transcendental subjectivity inhabits a space of conceptual articulation mainly conditioned by language, while empirical subjectivity is also conditioned by neurology, among other things. We should not be in a hurry to identify these two very different kinds of subjectivity, or to explain one in terms of the other. Rather, we should maintain the distinction, and work on the metaphorical topology of their interweaving. (See also What Is “I”?)
