I wonder what happens after we die (curiousity). I don't think I go somewhere else, since I have no reason to (doubt). Maybe nothing else comes after and I need to cherish what life I have left (hypothesis).<quoted text>
I disagree. It is curiosity not faith that is the basis of a scientific hypothesis. In most cases a hypothesis is merely an educated guess. In many cases the hypothesis is a commonly held belief that the researcher himself does not accept and is attempting to refute. A person doesnt test a hypothesis because he has faith that it is correct, he tests it because he has doubt.
"The doubter is a true man of science " ~ Claude Bernard
The experimentation/observation stage of the scientific method in this particular case would involve death. Until then, faith is all I have. I don't think there's an afterlife; I cannot prove it, but I have faith. I choose to invest my faith in an educated guess, rather than a death-denying psychological function.
