Uljana Feest’s 'Operationism in Psychology: An Epistemology of Exploration' provides a rigorous and insightful analysis of psychological research. This important contribution is a must-read for anyone interested in the philosophy and history of science. I’ve jotted dow some brief reflections below

I attended a retirement conference for the Gary Hatfield and came back with so much love and admiration for him and the wonderful scholars who gave tributes to him! A pioneering figure in the history/philosophy of psychology! And an amazing mentor, teacher, and friend to many

Great piece. I am uncertain about the last paragraph, though ("The German public were not aware that the assassination ... would lead them down the road to terror and atrocity"). I suspect that many Germans were well aware of what was going on, just like many Americans are now.

I will never celebrate a murder, least of all of a young father. But I do not consent to deify a moderately popular podcaster who said Black women "do not have the brain processing power" of white men, who said "Jewish dollars" fund "cultural Marxism," into a great man of history. I dissent.
More than 100,000 people, including President Trump and Vice President JD Vance, are expected to attend a memorial service for Charlie Kirk at a football stadium and nearby overflow arena in Arizona on Sunday.

We discuss his intellectual journey, interventions in creationism, sociobiology & the genome project, his philosophical evolution, and vision for philosophy serving the common good. A real privilege.

This looks extremely good by @sabinaleonelli.bsky.social So important to recognise differences in what 'open' means in #openscience. She shows for Bergson it's to cultivate meaningful social relationships, for Popper it's to exchange ideas and materials. The two can come apart! #philsci #metascience

This interview brought back happy memories of the three years I spent as a post-doc in Rheinberger's department at the MPI for the History of Science (about 20 years ago). Thank you, @tespiteri.bsky.social. Your smart and thoughtful questions turned this into a delightful conversation.
This week, distinguished historian and philosopher of science Hans-Jörg Rheinberger joins us to explore how scientific inquiry unfolds through experimental systems. We discuss 'epistemic things', technical objects, and their implications for how science is practiced and understood.

The thing about Colbert is that he has always been smart & fast & brave. Sure the Late Show is a less aggressive venue so what he does is often less pointed, but he does that well too while also finding ways to talk head on to power. I really hope we get to see him unleashed for the next 6 months
