On the possibility and nature of neurophilosophical study of Indic traditions. A Guest Post by Chakravarthi Ram-Prasad

[Note that this talk was delivered in the presence of the Dalai Lama and a large non-specialist audience, on the specific issue of ‘contemplative studies’ and neuroscience; hence the particular angle of approach. The issues in the main do pertain to the more general question of classical Indian theories of consciousness and contemporary neuroscience, although what I have said here would need to be re-phrased and re-oriented.]

What we need to ask ourselves is, why is the philosophy of the contemplative traditions needed for neuroscientific study, and conversely, what is the need of neuroscience for the philosophy? Let me try and suggest an answer. Contemplative science, as a discipline, is rapidly establishing itself, primarily as the bottom-up neuroscientific study of contemplation, with the added insights of psychological theories of behaviour and affect, as in Richie Davidson’s ground-breaking work on positive affect through alterations in brain and immune functions. This is clearly showing that neuroscience benefits from the study of contemplation, by treating meditative states as magnifiers of states of human consciousness, that can then be studied more directly.

In a profound sense, contemplation does not depend on science – but the philosophical thinking that informs contemplation could indeed benefit from both the informative analysis of the science and its explanatory limitations. To the extent all philosophy should seek to be consistent with the nature of reality available through scientific inquiry, so too the philosophy of contemplative traditions. But why should neuroscience take the philosophy of the contemplative traditions seriously? It is because we should look for a wider and more equal relationship between science and contemplation. By this I mean, not just between the science and the practice of contemplation – after all, much of the current research in contemplative science is exemplary in the respectful relationship between contemplative and scientist. Rather, I mean the relationship between science and the thought that informs contemplative practice.

Contemplative practices developed in close interaction with an intellectual tradition of debate. Even when the core of the contemplative experience was held to be beyond language, these traditions sought to explain why this was so; and they did this by carefully presenting their view of the world and human consciousness of it. It is now agreed that there should be an interaction between first-person study (what I experience and how I report it) and third-person study (what it looks like to a scientific observer, in terms of behaviour and brain states). But Buddhist, Hindu and Jain contemplation always had this interaction – Indian philosophy is often the third-person study of transformative experience. In order to understand the full significance of contemplation, therefore, neuroscience has to engage with the philosophy through which the traditions themselves understood contemplation.
This leads me to the first of four challenges that face contemplative science – which, if met, can be very fruitful.

  1. The first is that contemporary neuroscience is actually deeply influenced by philosophy – Western philosophy. Many key terms of study are drawn from ideas first articulated in the specific context of early modern Europe. In order to attain to the equal relationship I mentioned earlier, we should be sensitive to this historical fact, and make an effort to gain a better understanding of the Indo-Tibetan philosophy that directly informed the contemplative traditions. Terms like ‘mind’, ‘ego’, ‘knowledge’, ‘perception’, ‘intention’, ‘awareness’, ‘content’, ‘knowledge’ are not theoretically neutral. They come from specific philosophical contexts. All scientists, and not just the unexpectedly open-minded ones, must recognise the philosophical origin of scientific terms. Then, in the context of contemplative science, they must expand their horizons and interpret these terms from Indo-Tibetan perspectives as well. The first challenge, therefore, is the thorough re-conceptualisation of the terms of contemplative science.

    But there are other challenges, and I will list them from the general to the more specific.

  2. The second challenge has to do with a fundamental assumption of much neuroscience, and that is reductionism (which methodological commitment ultimately leads to some version of physicalism). Reductionism is the view that our phenomenological perspective, the what-it-is-like to think or feel anything, can be reduced to physical states. These states are neural. So the sound you hear when I speak – perhaps the boredom you are feeling just now – is just a matter of neurons firing in the brain. Such reductionism can entails physicalism, because it holds that all phenomenology is just physical states, that is to say, states of the brain. Treating consciousness reductively or physicalistically has led to enormous strides in our understanding of some elements of life. But this is a problem for respectful scientific engagement with contemplation, because, whatever the disagreements amongst themselves, the classical Indo-Tibetan traditions were all committed to a spiritual answer to life’s suffering, and would not agree that, in the end, there is nothing but physical states.
    Now, the strategy of relying on neural correlates of consciousness has taken us quite far. Both scientists and contemplatives can agree that phenomenal states are correlated to neural states. But how far can contemplative science go with this? The correlates are between first-person or self-reports and the states registered through fMRI or PET or other scans. But at least two problems loom. One is that because any human state of sufficient complexity (as in contemplation) requires report, such report must itself have a neural correlate. So an infinite regress threatens, each new brain state requiring a further report to be correlated with. Another problem is that reports, being linguistic, require concepts; but key meditative states in most traditions are held to be beyond conceptual activity. A major challenge, therefore, is to think of how to go beyond the neural correlates of consciousness. And study of behaviour alone will not do that.

  3. The third challenge is related to this. The conceptual vocabulary used in neuroscience has to be clarified. To a large extent, we are now dependent on proxies – i.e., observables standing in for unobservable phenomenal or dispositional states. For example, we look at variations in startle reflex for vaguer descriptors like calmness. Happiness is taken as certain neurons firing (or ‘getting frisky’ as one philosopher put it). But fMRIs are not what could be called ‘cerebrascopes’, machines for reading minds. They just read brains. But the relevant states are not so easily read through neural correlates or other physical correlates (like gaze saccades). The contemplative traditions make many distinctions between different types of happiness or tranquillity. A great deal of clarification of the concepts is needed.
  4. The final, and very technical challenge concerns the domination of computationalism in the standard theory of mind that informs top-down cognitive scientific theory. This is based on philosophical arguments that bet that the mind indeed works in ways that replicate formal logic (that is to say, like a computer does). Even if computationalism is re-thought as analogical rather than digital, so that its algorithmic functions are somehow less like computers and more like organisms, there are grounds for being pessimistic about organic consciousness being computational in any sense. Now, classical Indian reasoning structures cognitive processes in ways that are not captured by computational logic. Such classical Indian theories of reasoning are foundational to the Hindu and Buddhist approaches to the nature of consciousness – and therefore of the contemplative techniques for the transformation of consciousness. While syntactical processing may indeed be found in sets of synaptic structures, it is not at all clear that the symbolic representations used in computationalism capture the way we are conscious. A smoother theoretical flow between contemplative practices, the understanding of consciousness that informs them, and the appropriate approach to the neuroscientific data, is therefore required.

Let me end with an example of the sort of research that an Indo-Tibetan philosopher would dream of, if contemplative science meets these challenges, and becomes more integrated in future. Wolf Singer has hypothesised that phenomenal consciousness emerges from the formation of meta-representations through the coding of widely distributed neurons. We could pursue this line by looking for satisfactory answers to the following questions: is some kind of computation required to operationalise the study of contemplative states along these lines? Could there be alternative ways of operationalising the study of dynamical assemblies that seem to produce that heightened unity of awareness that contemplation appears to produce? And could such unity be better theorised through, say, Yogacara or Advaita accounts of consciousness?

Postscript: As I look back at this determined effort to be optimistic about such possibilities (given the context in which it was delivered, I felt I was pushing my questioning far enough already!), I wonder whether it even makes sense to attempt such bridging language. The trouble seems to be that we put into such language precisely such key concepts as already presuppose the possibility of bridging, whereas the fundamental question that has to be asked is whether what happens in these different domains is even bridgeable.
Finally, I need to make a key distinction. I am not particularly confident that neuroscience in its current paradigm and practice settles anything about the nature and content of the discourse of these contemplative practices. On the other hand, if the presuppositions of neuroscientific language are freighted with the terminology of modern European philosophy, one can at least try and imagine what it would be like to reconceptualize the vocabulary of that language through a translational philosophy of the classical Indian traditions. But that then leads us into the different, and perhaps larger intellectual question of inter-translatability as well as the pragmatic question of how scientific hegemonies are re-structured.

  1. I am delighted to see a post of this sort (especially nos. 2-4), given the rather uncritical reception of neuroscience in some quarters of philosophy as well as other domains, like law, where this is of urgent relevance and concern. We need more forthright (and critical) discussions of reductionism, physicalism, and computationalism (all of which I happen to find untenable with regard to ‘explanations’ of consciousness). My own view, for what it’s worth, is that consciousness, intentionality, and perchance even normativity are decisive properties or features or characteristics of our mental life which rule out even the plausibility of reductionist or eliminativist “hypotheses.” In fact, they might be said to rule out the various and more popular views proffered in the philosophy of mind on this score: emergentism, epiphenomenalism, and supervenience, for example, for “It cannot even be said that they are working hypotheses, because a working hypothesis is one that will rise or fall on the basis of relevant evidence, and there is no ‘evidence’ as such that could tell for or against ‘hypotheses’ of this sort” (Robinson 2008 below). May I be so bold as to suggest some contemporary works that are of help in this regard:

  2. Indeed, Patrick. And a helpful bibliography, some of which I’ve not come across. I’d also recommend the works of Mary Midgley:
    Science As Salvation: A Modern Myth and Its Meaning. Routledge, 1992.
    The Ethical Primate: Humans, Freedom and Morality. Routledge, 1994.
    ‘Darwinism and Ethics’ (1994) Medicine and Moral Reasoning ed. K.W.M. Fulford, Grant Gillett and Janet Martin Soskice

  3. Ah yes, thank you, I have several of Midgley’s books, my interest in her first provoked by her work on our relations to non-human animals and then later by her deceptively sophisticated views on scientism (‘deceptively’ if only because she writes so plainly and clearly that one fails perhaps to notice the high quality of argumentation!). Her range of interests as a philosopher is uncommon and refreshing…. And that reminds me of the work of a neurosurgeon and philosopher who also bears mentioning: Grant Gillet. He might be described as a neo-Aristotelian and post-Wittgensteinian philosopher (I know, that’s a mouthful and perhaps more confusing than not) who studiously avoids both reductionism and physicalism but is nonetheless an intriguing “naturalist” in the broadest and best sense (more in reference to our social world, our natural history and human ecology as it were, leaving us with a philosophically provocative narrative metaphysics and ethics and a ‘transcendental naturalism’). Readers thereby sufficiently provoked should see The Mind and Its Discontents (Oxford University Press, 2nd ed., 2009) and Subjectivity and Being Somebody: Human Identity and Neuroethics (2008).

  4. thank you, Ram, for the thoughtful post and Patrick for the further readings he suggest. I am pleased to see that so much work has already been done in this field. In my experience, neurosciences are often employed by philosophers as a sort of philosophers’ stone which should turn all their arguments into gold or destroy at once their opponents’ ones. As if neurosciences delivered crude, uninterpreted facts which could serve as the litmus test of each philosophical theory.

  5. This is a brilliant – and unfortunately all-too-rare recognition of the extent to which supposedly “neutral” neuroscience is pervaded by underlying assumptions from the Western philosophic position.

    Though not a philosopher (I’m a clinical psychologist) I attempted to point to some of the limitations and pitfalls in contemporary attempts to integrate Indian philosophic/psychological ideas with contemporary science: http://www.infinityfoundation.com/mandala/i_es/i_es_salmo_psych_frameset.htm
