Grasscarp, I wouldn�t disregard your post, all points are valid.
In the posts above, it is asserted that we cannot say they do not exist because we don�t know. By the same principle we could say that we cannot say they do exist, because we don�t know.
The disinclination I have is where you (and others) have convinced yourself that they do exist and have seen them, but will not consider they don�t and you haven�t. If it is a possibility that you haven�t seen a ghost, then it is possible you were duped by your imagination or were hallucinating etc. If it possible they do exist, then those things could have still occurred, or you genuinely saw a paranormal spectre.
Questioning experiences and looking for rational explanations, is not �rubbishing other peoples accounts of their experiences�. Since naomi has bought my religious beliefs into it, I am often told as a Christian on R&S that great claims require great evidence and that I am deluded. I can accept that a lot of people would think that, and they have valid reasons of their own for doing so.
If we were to base the point on quantities of personal experiences (earlier argument � loads of people have seen ghosts), then people who say that they have had a religious experience and have seen/heard God (yes Naomi, some people do say they have seen God), or were abducted by aliens, must be equally empirical.
Ludwig, in all honesty I think because I believe that we cannot see ghosts, that I would never see one. If I did see something that was ghostly, I would generally put it down to imagination or confused subconscious, or a floater in my contact lens. I believe in ghosts/spirits/souls in the same way I believe in God. They do exist, we just can�t see them. Am I deluded and irrational? Perhaps. I accept that is a possibility � and that is my point.
naomi, did you believe in ghosts before you saw a ghost?
