Ok, here is the setup. I am in a class called Philosophy of Natural Science. Over spring break, I need to write a paper, but I want you guys to help me pick the topic. The subject of this paper needs to be a scientific discovery/advancement which occured in the time since Darwin (about 200 years) wrote Origin of the Species. Here's the catch, I need to discuss three things about this scientific topic. First, I need to talk about the metaphysics of the topic, what does this topic assume is real? Secondly, I need to talk about the epistemology. What do you have to be able to know, I mean really know? Lastly, ethics. Is there something dodgy about it? I appreciate all suggestions. Try not to do the really obvious things like cloning or computers, as everybody else in class is going to do that.
