Good point Porkchop, the envirnoment we are raised in does play a big role in our belief system and ideals. Although being individuals we continue to be influenced by others who enter our lives throughout our life. Depending on not only the type of personality you are but the strength of your convinctions, anothers beliefs may challenge your own in a way that makes you take a step back and question what you have believed or thought to be true. Other individuals can include ppl you have never met but their influence comes from what they write, show (evidence of sorts) and/or publicly speak of. In my opinion anyway.
I also feel one of the strongest influences that can cause a person to change their opinion or belief, comes by way of personal experiences. For example (this is just one example): If you are of the belief that there is an afterlife but there is no such thing as the paranormal...meaning ghosts don't exist, spirits cannot interact with us, and it's not possible to communicate with the dead...no matter what you read nothing convinces you otherwise, and you chalk up experiences others tell as being their imaginations (for various reasons). But then you have an experience (or perhaps experiences) which you are simply unable to explain, nor chalk up to imagination as your wife/husband/brother/sister/friend etc experienced it with you...odds are your former belief about the paranormal will change, or it will open your mind enough to consider that at the least it's possible. So even though those first nine yrs of life taught you the paranormal does not exist and that remained your firm belief despite what you heard/read, a remarkable personal experience is very difficult to deny. Not that some ppl won't deny it and refuse to alter their belief, IMO some definitely will.
And there are psuedo-skeptics who not only do not believe in an afterlife or a higher power etc, they are certain anyone who claims to have experienced something unusual or who believes the paranormal exists are all just delusional. No amount of evidence will ever be enough. They feel so strong about their beliefs and world views they often join or start skeptic organizations to gather like minds and go on a full frontal attack of the paranormal, it's believers and researchers. Ridiculing others and attacking ones character is common place with extreme skeptics. Reputable published scientists from various fields (including nobel laureates)...whom are also parapyschologists and/or researchers of various aspects of both psi and the paranormal...have been openly critized and have had their work and characters attacked by psuedos, of which some are their collegues. Well that is a whole other topic in itself, best saved for a seperate thread.
Pam as for books. I have enjoyed some of Sylvia's books, but like Carrie and Peg I can't say I believe everything she says. I know lots of ppl think she is a fraud, along with John Edwards, James VanPraagh, Alison Dubois and a number of other known psychics/mediums. I'm sure they have all exaggerated their abilities at times and/or are vague in their responses when reading certain ppl, or they may only be 60% right most of the time and not 80 (just as an example). But to me it's not the level of psi ability a person demonstrates that I care about, it's their opinions, thoughts, beliefs and experiences that I consider. As for cold reading, I'm sure they do at times...but sit in any room of ppl or talk to someone you don't know and you can't help but pick things up from them, their facial expressions, body language speak as loud as words. Also a person who claims to be better than they are is not an anomaly, again sit in a room of ppl and listen to the stories being told, many exaggerate or embellish things..be it sports, work, the boss, relationships, or any story telling situation. In reading books or material, I will take what I relate with or which may seem to provide me the best answer to questions I have, and I leave the rest. I've read all sorts of books where I take nothing from them and feel they were a waste of my time and money. I also do lots of research on the net, there is a wealth of info at your fingertips. What I have found that no matter if your reading info at a pn related site, material from a known psychic, experiences of others and those who investigate the pn, etc etc opinions regarding ghosts and spirits are not that different. I just finished a book by Doreen Virtue, healing with angels, that I enjoyed, it has some interesting stories/comments in it. Books by those who investigate the pn can be interesting as well, as can material relating to meditation. Is there a specific read you are looking for? =)
