Contradictions will abound when we attempt to cling to any one belief. For instance, the UFO phenomenon is usually classified as "Paranormal"; the
field involving ghosts. I would like to think that there are extraterrestrial civilizations out there, but I don't "believe in ghosts" as most
people do. I have my speculations about them, but that's unimportant for now.
It isn't unnatural to base a belief on what we
want to be true. For instance, some people have never seen a UFO, but they fervently believe in
extraterrestrial life. Some people believe in heavenly rewards after death. They also want to believe in hell, because there
has to be some
sort of eternal punishment for those who have wronged them on Earth. Still others form their beliefs by merging principles from various belief
systems.
Ironically, there is a group of people who disagree with merging various beliefs to form a unique one. This too, is unimportant for now.
I think beliefs are, in themselves, decisions. We
decide to support concepts that appeal to us. Our decisions are based on our experiences,
which are unique to us alone. It is because of this that seeking out one's own understanding of the world is important.
Some belief systems also speculate that confusion heralds some progress in analyzing the world around you
I will conclude by suggesting this;
don't concern yourself too much with
what you believe in. Be careful about
how you believe it. For instance, you can believe in ghosts,
and ghosts alone. However, don't close your mind to the possibilities you currently don't support, such as the parallel dimensions, string theory,
male deity, and multiverse concept, which you mentioned. After all, there aren't a lot of 'definites' in the world we live in. Last I remember, the
very nature of reality is
still[i/i] being debated.
