It's only a theory
I imagine just about everyone who reads this blog already knows the following, but... A big group blog in philosophy of science has recently been started by Gabriele Contessa. It's called It's Only a Theory, and Gabriele has assembled an all-star cast of contributors. For reasons beyond me, he also invited me to join. So in the future, my philosophy of science posts will usually be cross-posted both here and there; however, the history and logic posts will be here only.
