If you are confused about why this is a debate, read this: (remember, this is a purely hypothetical situation) You are walking along the shore of a lake one day, when suddenly you hear a commotion on the water. When you look out across the lake, you see two figures drowning. One is your dog, (or cat, for you cat-lovers out there) and one is a man whom you've never met before in your life. Both are drowning, and you know that you will only be able to save one before the other one drowns. Who do you save? This was a question posed to me by my father a few years ago.
