I didn’t learn until I was in college about all the other cultures, and I should have learned that in the first grade. A first grader should understand that his or her culture isn’t a rational invention; that there are thousands of other cultures and they all work pretty well; that all cultures function on faith rather than truth; that there are lots of alternatives to our own society. Cultural relativity is defensible and attractive. It’s also a source of hope. It means we don’t have to continue this way if we don’t like it.
