David J. Blacker’s recent Deeper Learning with Psychedelics is a valuable attempt to think through the implications of psychedelics for philosophy and education. One passage in particular caught my imagination: Blacker points out the similarities between a psychedelic experience and René Descartes’s passage of radical doubt.
I’m delighted to be giving a talk at Psychedelic Science 2025, the annual conference of the Multidisciplinary Association of Psychedelic Studies. The conference (June 17-20 in Denver) promises to be really fun and stimulating. If you can make it, I’d love to say hi: registration isn’t cheap, but you can use code SPEAKER15 to get 15% off your registration.
I’m especially excited because my talk is really experimental, the kind of broad comparative work that would have got frowned on when I was in grad school. I’m still aiming to exercise scholarly caution to avoid saying anything false, trying to stay reasonably close to what’s in the texts, but I am writing about multiple thinkers whose source languages (classical Chinese and old German) I don’t know well: something which I think one has to do in order to investigate human cultural commonalities, but which would have raised every eyebrow in my PhD program. It’s the kind of project that an aspiring professor only undertakes after getting tenure; in my case, I can do it because I’m no longer trying for a faculty job.
Over the years I’ve managed to treat my insomnia in various ways, to the point that nowadays I can get a reasonably good sleep most nights. Mindfulness meditation – prescribed to me medically before I called myself a Buddhist – has been one big help with that. But just as big has been a medication called trazodone: primarily used as an antidepressant, trazodone in smaller doses helps one stay asleep and avoid the typical insomniac anxiety spiral where you wake up and worry that you can’t get to sleep and find that the worry makes it harder to get to sleep so you worry more. It does a great deal to take the edge off.
Meanwhile my dog, Christmas Belle (so named because we got her in a snowstorm on December 22), faced various anxiety issues that made her resistant and fearful to getting in the car and going to the vet. To help her cope with those situations the vet recommended… trazodone.

American psychedelic advocates received a great disappointment a couple months ago when the Food and Drug Administration refused to approve MDMA (ecstasy) as a treatment for post-traumatic stress disorder. The disappointment was great enough to lead Jules Evans of the Ecstatic Integration Substack to ask: “Is the psychedelic renaissance over?“
It seems silly to me to read too much into this one decision. It is not final; a new application could be made in a few years. More importantly, it is one decision, about one substance, by one agency in one country – for one purpose. (It was also a great disappointment for us in Massachusetts that our state voted down the ballot question to legalize psychedelics, but it too is just one state, where the question was extremely poorly promoted; Oregon and Colorado have proceeded with decriminalizing psilocybin.) If the entire “psychedelic renaissance” hung on the outcome of one agency’s decision or one state referendum, it would have been a shallow “renaissance” indeed. Even within the US there are already many other avenues for improving the legal status of psychedelics.

That said: Michael Pollan’s book How To Change Your Mind probably did more to kick off the supposed current renaissance than anything else, and one of Pollan’s most important takeaways in the book was, let’s not screw this up. Psychedelics were famously popular in the 1960s, but the messages around them were dominated by overenthusiastic salespeople like Timothy Leary, who had little sense of caution. The resulting backlash was so strong that it created the ignorant world I grew up in, in the 1980s and 1990s, where even video games felt the importance of including a heavy-handed “don’t do drugs” message – extending even to cannabis. What the FDA ruling should remind us of, is the importance of avoiding the mistakes of the ’60s – so that the renaissance can lead to an enlightenment, if you will.
While the cover of Seth Zuihō Segall’s The House We Live In claims the book draws its account primarily from Aristotle, the Buddha and Confucius, the deeper, animating influence turns out to be pragmatism. There’s no problem with taking inspiration from pragmatism as such; the problem is that Seth’s pragmatism is so relentless and extreme that it rules out of court all opinions that differ from it – including, it turns out, those of Aristotle, the Buddha and Confucius.
The excessive pragmatism in question is expressed above all in this sentence: “whenever we ask ‘what’s the meaning of “X?”‘, we are really asking, ‘what is the significance of “X” for maintaining and enhancing our lives.'” (107) This pragmatic claim is simply not true. Some of us are really asking the latter question when we ask the former. Seth would like it to be the case that all of us are asking the latter question. But it’s not.
One of the things that helped me realize the need for self-improvement by not-self-improvement was regular practice with the excellent Headspace meditation app, created by a former Tibetan monk named Andy Puddicombe. Headspace is at the epicenter of “McMindfulness”: the app normally charges for access but I get it for free as a work wellness benefit, and this arrangement has made Puddicombe millions of dollars. In turn, the app is a big reason I defend McMindfulness – especially through John Dunne’s hugely helpful distinction between “classical” and “nondual” mindfulness.
That is to say: the core practice in Headspace is noticing your emotions, positive and negative, as they arise, and reacting to them with nonjudgemental acceptance. And you do so, yes, in the present moment. Critics like Ron Purser correctly note that that present-moment focus is not found in classical Indian texts like the Pali suttas or Śāntideva – but Dunne notes that it is found in other premodern Buddhist traditions, like the Tibetan writings of Wangchuk Dorje. And I dare say that that present-moment technique is an improvement: one that does a better job than the classical tradition’s techniques at their shared goal of reducing our suffering.
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.
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.)
One of the more exciting scholarly developments of the century to date has been the growth of studies – previously hindered for too long by legal barriers – into mystical experiences induced by psychedelic drugs. In a landmark 2006 experiment, rigorously controlled and double-blind, Roland Griffiths’s research team at Johns Hopkins University found that people given high doses of psilocybin – the active ingredient in magic mushrooms – typically had experiences they described as “having substantial personal meaning and spiritual significance”, and bore several other characteristics in common with a certain kind of non-drug-induced mystical experience: a sense of merging with ultimate reality, a nondual sense of the unity of reality, a sense of awe or sacredness. This sort of mystical experience, it seems, can be chemically induced.
Longtime readers will know I don’t have much patience for the concept of “religion”. I continue to endorse thevariouscritiquesI’vemade in the past: the concept of “religion” confuses more than it clarifies. And yet as it turns out, I owe the concept of “religion” a favour.
What do I mean by that? I mean that I recently got a valuable and important opportunity which I don’t think I could have undertaken if the concept of “religion” didn’t exist.
