New(-ish) BJPS blog
Maybe everyone already knows about this, but the British Journal for the Philosophy of Science now has a blog: Auxiliary Hypotheses. There are multiple thought-provoking posts -- happily, it doesn't only announce tables of contents.
(And I might have my own substantive post up sometime in the near future... I'm wrestling with Quine for the umpteenth time, and hopefully will be able to write something here about it.)
