This uncertainty about death presents a serious problem though. In order to live my life in a manner I feel is intelligent, I'd really prefer a clear answer here. If I know that option 1 is correct, I'm going to live my life very differently than if I know option 2 is correct. I can't do both at the same time because they seem incompatible. I'd set different goals on one side vs. the other.
Living in a state of uncertainty doesn't quite work either. Uncertainty in this particular area gives me a poor basis for making intelligent lifelong decisions. It's fine that I'm uncertain about what the weather will be like next week. But uncertainty about death itself makes long-term planning nearly impossible unless I lower my consciousness, watch a lot of TV, and subscribe to the social context without thinking for myself. Think about it -- if you knew with absolute and total certainty what will happen to you after death, would it change how you're living your life today?
