I was talking to a couple of friends of mine about politics the other day. The conversation ended in a disagreement about whether or not one ought to adhere to principles of cultural relativism. That is, whether it is fair or legitimate to criticise the practices of members of another culture from the inescapable perspectives of ones own. I was arguing against cultural relativism but in the course of the discussion some arguments were raised which I hadn't considered before and which made me stop and reconsider my position.
My purpose in writing this is partially in order to get my thoughts in order and partly in the hope that the discussion can continue, 'cause it's one that interests me. I wish to wear my ignorance of many relevant topics on my sleeve and, as always, I'm completely open to the prospect of changing my mind.
My feelings were that open criticism of other cultures should be permissible. I felt that if we had carefully examined our own reasoning and motives, we ought to be allowed to criticise the practices of others, even if we understood that those practices may be the product of another culture and its historical context.
