Intentional Philosophy as the Neuroscientific Explananda Problem
The problem is basically that the machinery of the brain has no way of tracking its own astronomical dimensionality; it can at best track problem-specific correlational activity, various heuristic hacks. We lack not only the metacognitive bandwidth, but the metacognitive access required to formulate the explananda of neuroscientific investigation.
A curious consequence of the neuroscientific explananda problem is the glaring way it reveals our blindness to ourselves, our medial neglect. The mystery has always been one of understanding constraints, the question of what comes before we do. Plans? Divinity? Nature? Desires? Conditions of possibility? Fate? Mind? We’ve always been grasping for ourselves, I sometimes think, such was the strategic value of metacognitive capacity in linguistic social ecologies. The thing to realize is that grasping, the process of developing the capacity to report on our experience, was bootstapped out of nothing and so comprised the sum of all there was to the ‘experience of experience’ at any given stage of our evolution. Our ancestors had to be both implicitly obvious, and explicitly impenetrable to themselves past various degrees of questioning.
We’re just the next step.
What is it we think we want as our neuroscientific explananda? The various functions of cognition. What are the various functions of cognition? Nobody can seem to agree, thanks to medial neglect, our cognitive insensitivity to our cognizing.
Here’s what I think is a productive way to interpret this conundrum.
Generally what we want is a translation between the manipulative and the communicative. It is the circuit between these two general cognitive modes that forms the cornerstone of what we call scientific knowledge. A finding that cannot be communicated is not a finding at all. The thing is, this—knowledge itself—all functions in the dark. We are effectively black boxes to ourselves. In all math and science—all of it—the understanding communicated is a black box understanding, one lacking any natural understanding of that understanding.
Crazy but true.
What neuroscience is after, of course, is a natural understanding of understanding, to peer into the black box. They want manipulations they can communicate, actionable explanations of explanation. The problem is that they have only heuristic, low-dimensional, cognitive access to themselves: they quite simply lack the metacognitive access required to resolve interpretive disputes, and so remain incapable of formulating the explananda of neuroscience in any consensus commanding way. In fact, a great many remain convinced, on intuitive grounds, that the explananda sought, even if they could be canonically formulated, would necessarily remain beyond the pale of neuroscientific explanation. Heady stuff, given the historical track record of the institutions involved.
People need to understand that the fact of a neuroscientific explananda problem is the fact of our outright ignorance of ourselves. We quite simply lack the information required to decide what it is we’re explaining. What we call ‘philosophy of mind’ is a kind of metacognitive ‘crash space,’ a point where our various tools seem to function, but nothing ever comes of it.
The low-dimensionality of the information begets underdetermination, underdetermination begets philosophy, philosophy begets overdetermination. The idioms involved become ever more plastic, more difficult to sort and arbitrate. Crash space bloats. In a sense, intentional philosophy simply is the neuroscientific explananda problem, the florid consequence of our black box souls.
The thing that can purge philosophy is the thing that can tell you what it is.
