I have an avid spectator's interest in experimental philosophy, and do not pretend to expertise. I've recently seen, on email lists and blogposts, announcements for an experimental philosophy workshop called Armchair in Flames? It looks like an interesting conference; but a thought popped into my head about the title, which refers to the X-Phi anthem (performed here ).
Experimental philosophers take themselves to be committing the philosophical armchair to the flames, because (in part) they do surveys of the person-in-the-street's view on various philosophical topics. They thus test whether what professional philosophers say is commonsensical really is common sense, or rather some sort of idiosyncrasy or professional deformation.
But I just wanted to remark that this is only one way of committing the armchair to the flames. Another, which has been the dominant outlook in philosophy of science for the last few decades, is to discount heavily or even completely any deliverances of so-called common sense or intuition, and instead lean heavily or even completely upon the deliverances of mature sciences in formulating philosophical positions. This outlook was unequivocally in full effect in the department where I got my PhD, among faculty and students alike.
So in short, the experimental philosophers don't have a monopoly on casting armchairs into the flames -- the philosophers of science have been stoking that fire for a while already.
