Since the 1980s there has been a post-modernist movement in Western European archaeology where a strong influence from lit-crit, sociology and Continental philosophy has been felt. This has led, among other things, to radical relativism in some scholars, and to a tendency for archaeology departments to harbour and publish work that a) does not treat the archaeological record, b) does not aim at finding out what it was like living in the past.
I have criticised these tendencies at several occasions, as in this piece: “Archaeology is good fun but unimportant to most people“. Not long ago, the Gothenburg-published journal Arkeologen appeared with an exchange between myself and Claes Theliander on these issues. We have now put our pieces on-line (in Swedish).
Update 4 May: Claes has kindly permitted me to put the prologue of his thesis on-line with the rest of the writings. Now the whole debate can be read on-line.
