Mindful of the need to be productive, lan was caught a bit off-guard by some basic differences of opinion that emerged, specifically concerning WAC's responsibility to intervene in situations of human rights issues that concern cultural heritage. His own assumptions about the similarity of perspectives on this issue that he expected to find among WAC colleagues were discomforted and challenged by this. Upon reflection, he better understands the historical and contemporary reasons for these differences and took this to be a good lesson in unsettling our assumptions, which is probably what WAC is all about. © 2007 World Archaeological Congress.
