My paper on historical (anti-)realism is now available in EarlyView on @histandtheojrnl.bsky.social's website. It's my attempt at mapping the conceptual space in what I see as a deeply confused landscape, rife for unproductive polemics.

Today in two weeks (24.09), the autumn edition of our joint research seminar PHO2 will begin with Luke O'Sullivan (National University of Singapore) speaking about "Naturalism, History, and the Philosophy of the Science". Save the date! There will be more info also on the whole seminar soon.

Just a friendly reminder - a few more days to submit your paper for this virtual workshop!

If your report claiming that the quality of scholarship is declining over time is itself based on exceptionally poor scholarship, have you proved your point?

Worth reading this comment; really is quite eye-opening how shaky are the empirical foundations of this report
Boghossian et al.'s "Vanderbilt report" claimed "a deterioration in scholarly standards” in the humanities. What was their evidence? The companion reports have begun to trickle out. I argue that they show no evidence to support this claim. The report should be corrected or retracted:

This post is a gem. *chef's kiss* I would never be able to state the point so clearly.
calling this batch of caliper guys "race realists" is in a very loose sense accurate, in the way that supporting a genocidal war could be described as a permissive attitude towards defense spending, but the level of obsfuscation involved there is difficult to distinguish from outright lying

It's baffling to me that anyone would assume that this letter is a good faith effort to defend "academic freedom" and thus sign it as an endorsement of such defense. But then I remember that some people also assumed History Reclaimed really cared about objectivity. 🤷

Plagiarism is only one part of a much broader scope of academic misconduct, and ‘race realism’ is itself a form of academic misconduct: using academia to launder long-discredited and empirically refuted white supremacist propaganda. It is disseminating pernicious lies into broader society

I've just had the best experience with peer review in my career. Sure, the reports are probably fatal to the paper, but they are so detailed, respectful, and done with such care that I am thankful I received them. With all the horror stories that we see every day, this is refreshing.

There are innumerable issues with Pinker (e.g. his association with Epstein), but I want to highlight how all the experts on history of violence wrote a special issue in Historical Reflections specifically because Pinker was perpetuating numerous falsehoods www.berghahnjournals.com/view/journal...

Plenty to reflect about re: the Arday affair, but I'm going to repeat this one thing. The playbook the right used here is effective even though it's not especially sophisticated, as it relies on the audience to do the dirty work. I've been calling it "Trojan horse propaganda", let's go with that. 1/

That's basically anything I ever wrote for work.
Finally finished a full draft of 'Delineating Epistemic Injustice' - or rather, caffeine finished it, with me playing the role of a heavy-handed supervisor

I hereby publicly apologize for mocking the common practice of objection-anticipation in analytic philosophy, even when the objection is already dealt with in the main text. You were right - sometimes you really have to make this sort of thing. I'm listening and learning.

I hate so much that this needs saying, alas...

your apartment, the sport of basketball, and the Republic of Korea are all social constructs. mere recognition of this fact does not actually make the question of whether you are standing in your own apartment, playing basketball, or a Korean national up in the air until settled by op ed editors

We are so back
If you're a real academic in 2026, I assume you either look like an aging punk or hipster, or you post the dumbest memes imaginable on the internet in your spare time

I think about this a lot.
every time you write overly defensively you should remember that you are pursuing a strategy of writing careful sentences specifically for people who demonstrably either won't or can't read them
there is literally no amount of caveats or careful wording that will protect you from stupidity or bad faith, so you might as well say things straightforwardly and strongly to begin with.

Hello, sir, please let me tell you about Disco Elysium (for cool reasons).
Explaining to people that I'm into video games for cool reasons (art, aesthetics) and not for weird reasons (being a right wing weirdo with no other hobbies) is always fun and always goes super well

Surely the regularity with which these "Objectivity Defenders"™️ align with the worst of the far-right is just a fluke. A mere coincidence.
Real shame since I used to make the occasional joke with philosopher Paul Boghossian over the years whenever he was confused with reactionary philosopher Peter Boghossian, and we’d have a good laugh, since they’re both now pretty awful.

Also, Paul’s Fear of Knowledge was, in retrospect, for babies

My journey from a History undergrad to doing epistemology of history.
The spider bite leading one to become a methodologist:

"[substantive topic] is a interesting, I want to study it!"
[Learns about how topic is typically studied]
"Oh my god"
[Becomes a methodologist]
I cannot believe how many of these RCTs used a change/percent change outcomes.

Because the literature is so clear on the topic I honestly thought this issue was resolved!

Historians 🤝 analytic philosophers

It's so amusing that this very specific kind of onnoxiousness is one of the few shared traits between them.
