Thank you guys... From what I understand, without spending much time pondering your kind and most excellent answers, is that one needs faith to progress, and that the theory of annihilationism shows dukha as an unlikely chance (ahah, nice one).
However my feeling is that you are not really answering my question (sorry to be such a pain) by telling me the extremes and the middle way! Regardless of how nice a story it makes, I feel that my question remains! (I may be wrong...). And that is, how is nibbana as described by the Buddha (the definite end to an eternal string of rebirths) any different from death as viewed by annihilationists? In the former case, it seems to me that life simply lasted a hell of a lot longer than in the latter case (billions and billions of lives versus one short life, and then for both, the "candle is blown out").
Do you see my meaning?
