I was recently in the Canadian Museum of Civilization. (Does the USA even have a museum of civilization? And what does it signify that I need to look in a museum to find civilization?) One of their larger exhibits was on the subject of aboriginal peoples of North America, and one of the displays in the exhibit was of a memorial to a chief out of the Pacific Coast (I forget what nation), and to the many large potlatches he gave.
It didn't make an immediate impression on me, but as I was awakening the next morning, I realized that it indicated that other cultures -- other civilizations -- have had different relationships with stuff than ours does. Very different relationships, indeed.
