At the turn of the new year Steve linked the following statement by Michel Bitbol, "On the Primary Nature of Consciousness," in our review of key papers in the project of 'naturalizing phenomenology' or 'phenomenologizing nature'. We briefly discussed Bitbol's statement and wondered about the definition of word 'efficience' Bitbol uses, and I said I'd ask a French friend of mine to help us understand what that term means in the French language. She has now returned and responded:
"What I could find is the word "aptitude" as synonyme of 'efficience'.
So it would mean that neurosciences are incapable of "understanding
phenomenal consciousness because they don't have the right aptitude."
I think we should confront Bitbol's challenge to reductive neuroscience again if we want to continue to reflect here on the naturalization project. It seems to me that within the interdisciplinary field of consciousness studies it is now clear to the majority of participants that phenomenology and neuroscience must be integrated if progress is to be made. Here is the Bitbol statement for review; the bibliography he provided with that statement is included and presents papers we might be able to locate online.
"On the primary nature of consciousness (a short statement)

Nobody can deny that complex features of consciousness, such as reflexivity (the awareness that there is awareness of something), or self-consciousness (the awareness of one's own identity) are late outcomes of a process of biological adaptation. But what about pure non-reflexive experience ? What about the mere 'feel' of sensing and being, irrespective of any second-order awareness of this feel ? There are good reasons to think that pure experience, or elementary consciousness, or phenomenal consciousness, is no secondary feature of an objective item but plainly here, primary in the strongest sense of the word.
We start with this plain fact : the world as we found it (to borrow Wittgenstein's expression) is no collection of objects ; it is indissolubly a perceptive-experience-of-objects, or an imaginative experience of these objects qua being out of reach of perceptive experience. In other terms, conscious experience is self-evidently pervasive and existentially primary. Moreover, any scientific undertaking presupposes one's own experience and the others' experiences as well. In history and on a day-to-day basis, the objective descriptions which are characteristic of science arise as an invariant structural focus for subjects endowed with conscious experience. In this sense, scientific findings, including results of neurophysiology and evolution theory, are methodologically secondary to experience. Experience, o elementary consciousness, can then be said to be methodologically primary for science. Consequently, the claim of primariness of elementary consciousness is no scientific statement: it just expresses a most basic prerequisite of science.
But conversely, this means that the objective science of nature has no real bearing on the pure experience that tacitly underpins it. The latter allegation sounds hard to swallow in view of so many momentous successes of neurosciences. Yet, if one thinks a little harder, any sense of paradox vanishes. Actually, it is in virtue of the very efficience of neurosciences that they can have no grip on phenomenal consciousness. Indeed, as soon as this efficience is fully put to use, nothing prevents one from offering a purely neurophysiological account of the chain of causes operating from a sensory input received by an organism to the elaborate behaviour of this organism. At no point does one need to invoke the circumstance that this organism is perceiving and acting consciously (in the most elementary sense of 'having a feel'). In a mature cognitive neuroscience, the fact of phenomenal consciousness is bound to appear as irrelevant or incidental.
As a result, any attempt at providing a scientific account of phenomenal consciousness, by way of neurological or evolutionary theories, is doomed to failure (not because of any deficiency of these sciences, but precisely as a side effect of their most fruitful methodological option). Modern neurological theories, such as global workspace theory or integrated information theory, have been remarkably successful in accounting for major features of higher levels of consciousness, such as the capacity of unifying the field of awareness and of elaborating self-mapping. They have also turned out to be excellent predictors of subject's behavioral wakefulness and ability/inability of [to] provide
reports in clinical situations such as coma and epileptic seizure. But they have provided absolutely no clue about the origin of phenomenal consciousness. They have explained the functions of consciousness, but not the circumstance that there is something it is like to be an organism performing these functions. The same is true of evolutionist arguments. Evolution can select some useful functions ascribed to consciousness (such as behavioral emotivity of the organism, integrated action planning, or self-monitoring), but not the mere fact that there is something it is like to implement these functions. Indeed, only the functions have adaptative value, not their being experienced.
Even the ability of neurophysiological inquiry to identify correlates of phenomenal consciousness can be challenged on that basis. After all, identifying such correlates rely [relies] heavily on the subject's ability to discriminate, to memorize, and to report , which is used as the ultimate experimental criterion of consciousness. Can we preclude the possibility that the large-scale synchronization of complex neural activity of the brain cortex often deemed indispensible for consciousness, is in fact only required for interconnecting a number of cognitive functions including those needed for memorizing, self-reflecting and reporting? Conversely, extrapolating Semir Zeki's suggestion, can we preclude that any (large or small) area of the brain or even of the body is associated to some sort of fleeting pure experience, although no report can be obtained from it?
Data from general anaesthesia feed this doubt. When the doses of certain classes of anaesthetic drugs are increased and coherent EEG frequency is decreased, mental abilities are lost step by step, one after another. At first, subjects lose some of their appreciation of pain, but can still have dialogue with doctors and remember every event. Then, they lose their ability of recalling long-term explicit memories of what is going on, but they are still able to react and answer demands on a momentary basis. With higher doses of drugs, patients lose ability to respond to requests, in addition to losing their explicit memory; but they still have 'implicit memories' of the situation. To recapitulate, faculties that are usually taken together as necessary to consciousness are in fact dissociable from one another. And pure, instantaneous, unmemorized, non-reflective experience might well be the last item left. This looks like a scientific hint as to the ubiquity and primariness of phenomenal consciousness. Of course, a scientific hint does not mean a scientific proof (at any rate, claiming that there exists a scientific proof of the primariness of elementary consciousness would badly contradict our initial acknowledgment that objective science can have no real grip on pure experience). The former scientific hint is only an indirect indication coming from the very blindspot of science: the pure passing experience it presupposes, and of which it retains only a stabilized and intersubjectively shared structural residue.
Should we content ourselves with these negative remarks ?As Francisco Varela has shown, one can overcome them by proposing a broadened definition of science. Instead of remaining stuck within the third-person attitude, the new science should include a 'dance' of mutual definition taking place between first-person and third-person accounts, mediated by the second person level of social exchange. As soon as this momentous turn is taken, elementary consciousness is no longer a mystery for a truncated science, but an aknowledged datum from which a fuller kind of science can unfold.
