"Most mainstream Judaeo-Christian postulates the immortality of the soul. But it seems to come up against mainstream history and science."
Does it? Science does not answer questions that defy empirical inquiry.
I have been told that we are spirits first and that we are having a temporary in-body experience. We don't currently remember our time before because this period of our eternal existence is a special test. It's a time of development and preparation. After death we will resume our real lives and eventually get our bodies back, permanently, thanks to Jesus Christ.
My whole life I've been considering ways to either prove or disprove that narrative, but it turns out to be strictly unfalsifiable thanks to the part about forgetting our previous experiences. Does that mean the narrative is false? Certainly not. Does that mean it's true? Again, certainly not.
Should I discard that narrative because it's unfalsifiable? Well, I can't prove empirically that my mother loves me, but I hold on to that belief anyway because I think it's right.
It's wrong to burden science with every important question. When we torture science into answering unfalsifiable questions, we change its definition and confuse everyone. I love that the domain of science is constantly expanding and more questions are becoming empirically answerable every day, but we need to maintain our humility and recognize that science still has little to say about the basic questions of our existence.
I wholeheartedly agree that if this life is all there is, there's something seriously wrong. My wife, my children, my parents, my family, and my friends deserve more than just this. I see evidence of their infinite potential. What can I do to help them reach their true, immortal potential?
I don't think I'm the first person to recognize the infinite potential of others. I think more intelligent people figured this stuff out long before I did. I think some of those smart people decided to do something about all the wasted potential in the universe. I think we are all beneficiaries of those smart people and that life isn't anywhere near as bleak as it seems.
If not, someone somewhere is eventually going to be in the right place at the right time and they will set things in motion so that future people will have eternal lives. They will probably decide that eternal beings should have extraordinary experiences such as 100 year long blind tests in planet-sized classrooms. Oh wait. :-)
Anyway, forgive my ramble. Life is extraordinary and hard to pin down.
