the first thing you have to ask when you approach the subject is how you approach it at all. it is a far out subject. trying to figure out what the reactions would be would be even more difficult. we have come up with three approaches. history. there are times in the past that we thought we discovered life. you can see what the reaction was. also, the nature of the discovery, and thirdly, a culture contact in various analogies that can help illuminate what the discovery would be like. history, discovery, and analogy are my three approaches. can we go to those one by one? tell us about history and what there is to learn from our own history about what our possible responses might be to discovery of life. a great deal, although you have to be careful to say you cannot predict the future. it is an analogy itself. if you use history, you can record in detail what happened, but there is projection as to how it might affect the future. let me take three cases in past hi ....
