Deletion of Philosophical theory

Comment: I don't believe this to be a neologism because it hasn't been recently coined.  This phrase has turned up in numerous sources through searches on google books and google scholar. All that this needs for a proper article is a definition from a reliable source.  Oddly enough, I haven't found a straight-forward definition of the term, perhaps because the meaning is implied by |common sense. I can't imagine that this phrase hasn't been elucidated anywhere; I'll look it up in the library when I visit in around 12 hours
