Missed a couple of years recently, but this was my 6th (or 7th?) attendance at the Hay-on-Wye “How The Light Gets In” philosophy, science, policy and music festival. It’s over 4 days, but it’s so packed with content, I’m exhausted after just two these days.
Just posting a few thoughts this year, rather than detailed reviews of the talks, dialogues and music. [I have notes elsewhere for my own reference. As ever, Dave Snowden was in attendance – got one brief chance to say “Hi” in person.]
Apart from a few new faces – keepers for future dialogue – no really new topics or ideas this year, and the main new impression in 2025 was Hilary Lawson’s. As founder and director of IAI and HTLGI he’s had plenty of previous stage time at these events, but noticeable was his urgency, his visible frustration at getting his non-realist “Closure” (2001) agenda across [2003] [2009].
I ended on watching Tom Robinson‘s set on the Saturday evening. Given the nature of the event, the music tends to to be light relief entertainment from the intellectual content, for me anyway, so I’ve only occasionally noticed specific acts on previous occasions, and until the day, I hadn’t noticed Tom was even on the bill. Good to see and hear his full hour set – telling his life stories, and the loss of Danny Kustow – as well as playing his songs, which meant it was 9:30pm before I was in the car for the 5.5hr drive home! Lovely bloke. One of his songs – a re-telling of American Pie for the British which includes reference to the Eric Clapton / Enoch Powell remarks that spawned Rock Against Racism and the Anti-Nazi League back in 1978. The last time I saw Tom was Sunday 30th April 1978, the Trafalgar Square rally and march to the RAR/ANL gig in Victoria Park, Hackney. What a day!
Both Jeremy Corbyn and Richard Tice on the bill – enlightened freedom of speech n’all that – how the light gets in – despite which the latter drew some naïve AntiFa protests 🙂 Saw the latter claiming common sense – don’t we all? But my focus was / is the philosophy<>science interface / overlap / relationships so I properly attended:
Catherine Mayer – Stranger Than Fiction, writer / journalist in conversation with fellow journalist / writer Mary Ann Sieghart.
(Ever present philosopher Barry C Smith wine-tasting-based philosophy session, I skipped.)
John Dupre, Ivette Fuentes & Alex Rosenberg discussing “whether physics holds the answers to all our questions” – spoiler, it doesn’t. [My agenda.]
David Goodhart, Sherelle Jacobs & Richard Tice – draining the swamp, smaller government through efficiency etc. Sherelle new to me, a keeper.
Hilary Lawson, Steven Pinker, Barbara Tversky and Sophie Scott-Brown – debating the relationships between thought, language and reality. No surprises [my agenda] other than Lawson pushing his anti-realist “Closure” agenda very hard, despite having much previous stage time referencing it – as the founder / director of the IAI / HTLGI event. (Pinker actually used a quote I use from his wife Rebecca Goldstein, that no physicist or philosopher’s work is complete without ontological commitment to say “and this is how the world really is” unless like non-realists you deny reality. So close to my triadic position which is to remember that reality is strictly “posited” as being out there and your ontology is “deemed”. Reification is exactly that. Treat it as “real” by all means, but never forget.)
Ivette Fuentes – breakfast conversation with the Mexican quantum physicist, sharing her story of her interest in the topics that have shaped her work in QM.

“Hat on” reminding her of the rigour of physical science, when switching hats between Philosophy and Science/PoS 🙂
Robert L Kuhn, Masimo Pigliucci, Maria Balaet & John Dupre – on the biology of conflict (vs collaboration). Balaet neuroscientist, another keeper, new to me.
Maria Balaet, Joanna Moncrieff & Norman Ohler – on the historical and social place of psychoactive substances – ranging from caution to enthusiasm, via empiricism and pragmatism as ever.
(Missed Goodhart, Mayer & Sturgeon on gender in democracy. #ViveLaDifference)
Paul Bloom – on Utopia – impossible and actually undesirable, but that doesn’t mean we shouldn’t try to get close. Someone I knew of, student of Pinker, but first experience for me. A keeper. (Also author of “Against Empathy” – see footnote.)
Eric Kaufmann – on the End of Woke. Business-like presentation on the history from original political correctness and the need for narrower understanding of the specifics: “Today’s leaders… need to understand Kaufmann’s defence of democracy before it’s too late.” — Trevor Phillips, about says it.
Carlo Rovelli, Alenka Zupancic & Slavoj Žižek– on the self in the world. Entertaining to hear Žižek as usual, agreeing with lots of Rovelli, especially the Buddhist / Nagarjuna angle.
Hilary Lawson & Slavoj Žižek – refereed by Gunes Taylor – non-realist philosophers both, going beyond Truth and Reality. Again, Lawson quite urgent in pushing his “Closure” view and the incorrigible Žižek agreeing with his endless anecdotes and jokes. (I’ve been sympathetic to Lawson’s view since 2003, properly reading him in 2008, formative part of my worldview, but clearly the 2025+ “polycrises/metacrisis” has spurred his new-found urgency.)
Tim Maudlin standing in for Avshalom Elitzur – on imaginary numbers in parallel mathematical formalisms in physical theory, including QM and Schrodinger. (No mystery – just an “accounting practice” to keep independent / orthogonal – more strictly, co-dependent / complementary – real variables distinct when combined in single dynamic equations or formulae. #GoodFences. Also fascinating that he included Navier-Stokes in his examples of parallel formulations – Engineers (and cosmologists) deal with this all the time, but these “diffusion as flow” views gaining traction at quantum levels too.) [Another new / keeper]
Claire Blencowe, Paul Bloom and Michelle Terry – provoked by Matt Taylor – on the distinction between roles we artificially “play” and roles we authentically “fulfil” as our-selves in the real world. A great place for me to end.

Note: On the Friday I visited a handful of Hay’s dozens of used book shops, and failed again to find a copy of Iain McGilchrist’s “Against Criticism”. (This, like “Against Empathy” (by Paul Bloom above), is a memetic extension of Paul Feyerabend’s “Against Method”(*) – not literally “against” but against over-zealous / over-reach / distortion of its intended use – see topical woke / anti-woke / Musk “empathy killed the west” etc and (*) see Rules – guidance for wise etc. In Bloom’s case it’s a warning against our biases, where we get to feel good empathising with in-groups, to the detriment/displacement of any actual empathy with out-groups.)
