Note that experimental philosophy, even when viewed in this positive light, is at most an addition to our philosophical armoury, not a new way of doing philosophy. For once we have sorted out the intuitive principles behind our philosophical judgements, whether by armchair reflection or empirical surveys, we still need to assess their worth.  Even if the claim that we think a certain way is supported by hard empirical data, this doesn’t make that way of thinking correct.  That can only be shown by subjecting that way of thinking itself to proper a posteriori evaluation.
