Let's assume a tribe is discovered that had zero interaction with the rest of the world. [View All]

And its culture is ancient, with a way of life that has undergone no change at all for centuries. And now let's also assume the culture contains some things that are totally inconsistent with our values, for instance elements of slavery, human sacrifice or something similar.

What is the morally correct way to deal with such a group of people? Should they be left alone and essentially ignored? Should they be treated as savages who need to be educated into modern life? Should there be some form of diplomatic relationship? Should such a relationship include efforts to persuade them to let go of elements of their culture that are contradictory to our values? Should we sell them Coca Cola?

I realize that in the present world this situation is kind of idealized, since in most parts of the world, some form of interaction has happened already long ago, and we are mostly dealing with the consequences of these interactions, rather than a completely undisturbed system. But philosophically this questions is still interesting.

I am asking because I struggle with this question myself. I grew up watching a lot of Star Trek, and used to think the "prime directive" is a good idea. However, I do realize that there are problems with this philosophy that become most evident when there are things such as widespread slavery involved.

I would like to read some opinions on this topic. I'll be leaving my desk now, but will have a chance to read the replies either later today or tomorrow.
