Following up my talk on psychedelics and mysticism, Osheen Dayal of the Canadian branch of MAPS just interviewed me on the same subject for their video podcast. In the interview we talk about a wide range of subjects from my personal Buddhist story through St. Teresa’s angel to Elon Musk. Have a look!

How can we reconcile Buddhism with expressive individualism (“be yourself”) and with natural science? When I had previously turned to Wilfrid Sellars for help on this question, I had compared Sellars’s view to two Buddhist metaphysical positions on ultimate truth, which are quite different from each other. One of these was Buddhaghosa’s view that ultimate truth is reductionist, and I no longer find that comparison helpful. But I also turned to Śāntideva’s view that the ultimate is normatively inert, with no good or bad involved. Śāntideva’s view rejects Buddhaghosa’s in some very important ways – and I think that philosophically his metaphysics is considerably more powerful.

That’s a big deal for me because, having come to my Buddhism in Thailand, I have generally viewed myself as a Theravādin like Buddhaghosa. I’ve been skeptical of the most famous piece of Śāntideva’s metaphysics, his ethical deconstruction of self and other in chapter VIII of the Bodhicaryāvatāra. I’m not convinced by his or any other argument for a universal impartial altruism – a key Mahāyāna doctrine. Yet I do now find myself moving closer to a Mahāyāna or at least Madhyamaka view, because of a different aspect of Śāntideva’s metaphysics: the metaphysics of emptiness in chapter IX, which I think are considerably deeper.

When I was in grad school, a big academic fashion was to heap scorn on the idea that mystical experience could be something cross-cultural: everything was reducible to social context, and the similarities of experience didn’t really matter, as I had once argued myself. But the roots of that idea were often more asserted than argued: the famous article by Steven Katz, which inaugurated the approach, didn’t bother to justify its assumption that “There are NO pure (unmediated) experiences“, assuming perhaps that italics and capital letters were the only support necessary.

A little while ago I noted how Robert Forman’s collection of essays illustrate “cool” mystical experiences, where distinctions of senses and self drop away and the mind ceases to fluctuate, in sources as varied as the Indian Yoga Sūtras, the Ukrainian Hasidic Dov Baer and the German mystic Meister Eckhart. Something similar seems to be going on in the Sri Lankan systematizer Buddhaghosa and the medieval English Cloud of Unknowing, which both involve, in Ninan Smart’s terms, a “systematic effort to blot out sense perception, memories, and imaginings of the world of our sensory environment and of corresponding inner states.” And it turns out that once your mind is no longer prejudged to deny any cross-cultural similarity, you start noticing it in a lot of other places.

Artificial intelligence is all the rage right now, and for good reason. When ChatGPT first made the news this December, I tested it by feeding it the kind of prompt I might give for a short comparison essay assignment in my Indian philosophy class. I looked at the result, and I thought: “this is a B-. Maybe a B.” It certainly wasn’t a good paper, it was mediocre – but no more mediocre than the passing papers submitted by lower-performing students at élite universities. So at Boston University my colleagues and I held a sold-out conference to think about how assignments and their marking will need to change in an era where students have access to such tools.

As people spoke at the conference, my mind drifted to larger questions beyond pedagogy. One professor in the audience noted she’d used ChatGPT herself enough that when it was down for a couple days she typed in “ChatGPT, I missed you”, and it had a ready response (“I don’t have emotions, but thank you.”) In response a presenter noted a different AI tool called Replika, which simulates a romantic partner – and looks to be quite popular. Replika’s site bills itself as “the AI companion who cares”, and “the first AI with empathy”. All this indicates to me that while larger philosophical questions about AI have been asked for a long time, in the 2020s they are no longer hypothetical.

Experiencing different ultimate unities

Defenders of cross-cultural mystical experience are right to note that in many widely varying cultures, respected sages have referred to the experience of an ultimate nonduality: a perception that everything, including oneself, is ultimately one. But one might also then rightly ask: which ultimate nonduality?

Nondualism may be the world’s most widespread philosophy, but it can mean different things – not merely different things in different places, but different things in the same place. Members of the Indian Vedānta tradition frequently proclaimed that everything is “one, without a second”, in the words of the Upaniṣads they followed. But they disagreed as to what that meant. Śaṅkara founded the Advaita Vedānta tradition – a-dvaita literally meaning non-dual – which argued that only the one, ultimate truth (sat, braḥman) was real, and all multiplicity and plurality was an illusion. His opponent Rāmānuja agreed that everything is “one, without a second” – but in his Viśiṣṭādvaita (qualified nondual) school, that meant something quite different. All the many things and people we see around us – what Chinese metaphysicians called the “ten thousand things” – are parts of that ultimate one, and they are real, not illusory.

There are likely a number of religious-studies scholars who would cringe and groan at Roland Griffiths’s studies of drug-induced mystical experience. I haven’t gone into their literature in a while, but I think it would be easy for them to say Griffiths is setting the study of mysticism back many decades. Because Griffiths’s stated conception of mystical experience is one that many religionists would already have considered very dated – even when I was studying them twenty years ago.

I say this because Griffiths’s first groundbreaking study, in indicating that many psilocybin volunteers had mystical experiences, measures mystical experience using a questionnaire based on W.T. Stace‘s Mysticism and Philosophy, published in 1960. And when I was in grad school twenty years ago, Stace’s work was often considered impossibly backward.

A speculation on Ken Wilber’s experiences

As I reflected back on the works of Ken Wilber recently, a thought occurred to me: man, that guy must have done a lot of drugs.

I don’t recall Wilber ever saying anything about drugs in his work one way or the other. Given that he wrote most of his work under the restrictive régime of the late-20th-century US, that shouldn’t be a surprise; caution is valuable. Yet he is an American baby boomer deeply interested in spirituality and mysticism; that is the sort of profile that leads one to expect significant experimentation with psychoactive substances.

But more importantly than his demographic: Wilber’s philosophy is very much the sort of philosophy one would expect from someone who had had profound drug-induced mystical experiences. A theme throughout Wilber’s work is the importance of experience to knowledge, a view that Wilber’s late work comes to call “radical empiricism”. He claims throughout his work that the essentials of premodern wisdom traditions – Platonism, Buddhism, Christianity – are to be found in mystical experiences, and in replicable practices that lead up to those. Some years ago I wrote an article debunking this claim: I don’t think that a reasonable historian can look at the evidence we have of Confucius or Moses or Jesus or Zhiyi (Chih-i) and still say that the essentials of their teachings come from replicable experiences. (We could reasonably say that Moses at the burning bush was having a mystical experience, but it was not in any way replicable.)

I now begin my responses to Chakravarthi Ram-Prasad on the thought of Buddhaghosa. Let me first reiterate a point I made early on: what I refuse is the interpretation that Buddhaghosa’s understanding of ultimate, conventional and the aggregates are merely phenomenological and not ontological. That is, I reject Heim and Ram-Prasad’s claim that “Buddhaghosa does not use abhidhamma as a reductive ontological division of the human being into mind and body, but as the contemplative structuring of that human’s phenomenology.” Emphasis added. I am not, and never was, denying a phenomenological element to Buddhaghosa’s ideas; I would have no objection to the claim that Buddhaghosa uses abhidhamma categories as both an ontological division of a human being and as a structuring of that human’s experience (contemplative or otherwise). As far as I can tell, the ontology/phenomenology distinction is not one that Buddhaghosa employs; in Heim and Ram-Prasad’s article I do not see any evidence that Buddhaghosa makes such a separation.

Indeed that very distinction of phenomenology from ontology seems to me to depend on a distinction between subject (the topic of phenomenology) and object (the topic of ontology). Such a split seems to me one that Buddhaghosa is unlikely to want to make, given his commitment to deconstruct the self/subject. And I think the refusal of such a split may be lent support by Heim and Ram-Prasad’s article itself, on points which I did not refer to because I suspect I am in agreement with them: namely, that Buddhaghosa makes no significant split between mind and matter.

In my previous post about the way the mind’s automatic processes get things wrong (and how that point is important to Buddhists), I turned to the experiments of Daniel Kahneman (and Amos Tversky) on false cognition. I claimed that the kind of automaticity they describe is a better explanation of what Freud would have called the unconscious mind, citing the quip that “the unconscious is unconscious not because it’s repressed but because it’s not conscious.”

Some excellent comments from Patrick O’Donnell took me to task for this claim. Patrick is pointing to the importance of the distinction between cognitivist approaches like Kahneman’s on one hand, and a very different kind of modern Western psychology on the other. Continue reading →

Unconscious illusions

Buddhist texts frequently stress the liberating power of prajñā or paññā, metaphysical insight. It is one of the three major components of the path in early texts, one of the six perfections in Mahāyāna. To know the truth about existence – its nature as impermanent, essenceless, unsatisfactory – is to liberate one’s mind and be unattached. In the Pali Vinaya, the Buddha’s first disciples Sāriputta and Moggallāna attain liberation from suffering as soon as they hear the Dhamma Eye: the phrase “Whatever can arise, can also cease.” Śāntideva at Śikṣā Samuccaya 264 says na śūnyatāvādī lokadharmaiḥ saṃhriyate: one who takes the position of emptiness will not be attached to worldly phenomena.

But something seems odd about these claims – perhaps especially to a beginning student of Buddhist philosophy. We might well acknowledge the tradition’s supposed truths as truths – and yet still be just as mired in suffering as we were before. I know I didn’t get liberated upon hearing that what can arise can cease, and you probably didn’t either. David Burton in his Buddhism, Knowledge and Liberation puts the problem well:

I do not seem to be ignorant about the impermanence of entities. I appear to understand that entities have no fixed essence and that they often change in disagreeable ways. I seem to understand that what I possess will fall out of my possession. I apparently accept that all entities must pass away. And I seem to acknowledge that my craving causes suffering. Yet I am certainly not free from craving and attachment. (Burton 31)
