and why do you disregard the next part of my post? the highest authority is not science, or faith, but your own experience. someone who has experienced a ghost knows they exist. someone who has not experienced a ghost has no experience on which to base an opinion. they can still have an opinion, but to say they don't exist is simply being close-minded. There is such a massive logical fallacy here I don't know where to start (unless this is just a joke). Actually, science is the highest authority. This is because scientific thought works on the basis that there has to be evidence for something existing before it is said to exist. How is saying something does exist just because of your own experience (inspite the lack of evidence) not close-minded? If anything people who are sure they've seen something are far more close-minded and biased because they are not considering what evidence there is to say what they saw is true. People who haven't "seen" ghosts do have experience to base an opinion on, the experience of not having witnessed anything. These people are the least biased because they can look at evidence objectively.
