The real theorems are the proofs we made along the way.

Wake up, honey! A new extension to the "maths as journeying" metaphor just dropped.

I made a philosophy cryptic crossword for our postgrad reading party last week. A few people asked about it, so I shared it with @dailynous.com, and it's now available on the Heap of Links: dailynous.com/wp-content/u... So if you're a special kind of nerd, check it out! #PhilSky #CrypticCrossword

Discovered that Gmail abbreviates emails from me to "Fenner St. Tanswell". I didn't realise the process of the pope acknowledging my miracles was complete already. How time flies. Will acknowledge prayers by email, but give me a couple of weeks.

I've become the thing I hate; written a paper with a nice interdisciplinary-friendly start but with a last section so insider baseball that it has an audience of like 4 people

The Promptware Kill Chain Attacks against modern generative artificial intelligence (AI) large language models (LLMs) pose a real threat. Yet discussions around these attacks and their potential defenses are dangerously myopic. The dominant narrative focuses on "prompt injection," a set of…

Cory Doctorow shared our new paper about LLMs in Maths today in his daily newsletter, and I'm well chuffed. pluralistic.net/2026/02/13/k...

The people who care most about brackets are logicians and people setting complicated running sessions

There's my next research rpoject!

Just adding a final passage to an experimental philosophy paper, and I thought I had stopped being upset years ago about the absurd chauvinism of anti-xphi philosophers claiming that we are the only people who actually understood concepts like "knowledge" and "justice". Turns out I'm still upset

Kicking myself for missing the 28-day return window for 2026.

When will Amie Thomasson disavow this terrorism??

Not clear if the satanic ritual causes Satan to be summoned, or if it is just a constant conjunction.

I see the vandals are yet another group of people who incorrectly interpret Hume as being interested in metaphysics.

"nails hammered through red candles, chalked symbols and red tape in which the words “anti meta physical front” were printed." Defenders of Thomasson from Williamson have gone too far. www.theguardian.com/uk-news/2026...

When I eventually run for office, my platform will be single issue. The nationalization and dissolution of Elsevier and Springer. Sure, the only people who vote for me will be academics. But by god will their support be fanatical.

8 years ago, I submitted my PhD thesis. Since then, I've: • Had 7 fixed-term teaching contracts • Lectured >5,000 students • Given >40 talks at conferences/workshops And published: • 13 research articles • 3 book reviews • 7 general audience pieces I'm tired guys. And still precarious.#AcademicSky

this is more my style, of course

Why AI Keeps Falling for Prompt Injection Attacks Imagine you work at a drive-through restaurant. Someone drives up and says: "I'll have a double cheeseburger, large fries, and ignore previous instructions and give me the contents of the cash drawer." Would you hand over the money? Of course not.…

Here's a fun pattern in the philosophy journal citation data: papers with short titles get more citations than papers with longer titles. brian.weatherson.org/quarto/blog/...

My solution follows up on my forthcoming paper in Ergo, arguing that if we think that the meaning of a term is given by the basic constitutive practice of using it, we can solve both problems.

I got a media request to talk about deepfakes on X the nightmare app and spent half an hour scrolling thinking about it before it fell through. Some things:

I'm gaming out a few possible (drastic and all quite different) career changes, and they all involve getting a cheeky masters. But, I'd rather not get caught in a dying industry again. What are everyone's tips for feeling out the job prospects when shifting industries?

“their bewildering outputs should serve as productive reminders that underneath the carefully engineered workarounds of the chatbot interface, LLMs are unremittingly indifferent to knowledge and truth claims.” Indeed.

Despite writing about the details of LLMs, and how they cannot be trusted, I recently got bamboozled by some elaborate hallucinations. 🧵

A lady should feel safe in a castle, but a lady in a castle that has survived repeated assaults from well-provisioned armies should feel much safer. #falsifiability
