Science is a neutral tool but the people who use it aren't always neutral themselves. The scientific method is very simple.
1. Look at your experience.
2. Make a hypothesis.
3. Test.
What's so objectionable to that? How does it not apply to the immaterial world?
That's what I think. It doesn't so much matter why it happens, but that it actually does.
I hate that answer. What the crap is the point of metaphorical immortality?
I think reincarnation exists but I don't feel that it does. Almost everyday I think "I am going to die and there is nothing I can do about it". It scares the sh*t out of me. Not because "it's the fear of the unknown". I'm just very upset that death might be the end.
