Music is arguably the most affecting of the arts; intelligible to all people yet untranslatable into any other idiom. To Schopenhauer it was a direct… - Derren Brown

Séances date back to the 1800s after three sisters by the name of Fox claimed to be able to contact the dead. They toured America with their demonstrations and attracted the rich and famous and by the end of the century séances had taken off all over the western world. Spirits were manifested, tambourines flew, ectoplasm impossibly erupted from entranced mediums. Then, after forty years of this, rather embarrassed by what they’d started, one of the sisters, Margaret Fox, confessed that they were frauds. The miracles which had started it all off had been a scam. But her confession made very little difference and spiritualism continues to appeal to many people today.

Each of us is leading a difficult life, and when we meet people we are seeing only a tiny part of the thinnest veneer of their complex, troubled existences. To practice anything other than kindness towards them, to treat them in any way save generously, is to quietly deny their humanity.

Being open minded isn’t about accepting things mindlessly. Being open minded is about having the information and then making the best decisions you can. A chap called Ian Rowland who wrote a good book on cold-reading made the point that if you’re a chef and you think, ‘well I know if I put poison in this soup and give it to these 200 people it’s going to kill them but, hey, I’ll be open minded’, that’s not being open minded, that’s just being ignorant. That’s just not working with the information you’ve got. So we have information on things like placebo effect and information about cold-reading. These things exists – false memories and anecdotal [evidence], all those things that are important – and taking that on board is just about being able to make better decisions. That’s about being truly open minded. Ignoring them and putting them to one side in this pursuit of easy answers and ‘intuition is the be-all and end-all of truth’, that’s not being open minded at all. I think that’s very narrow minded and certainly to laugh at people who say that evidence is important, I think that’s hypocrisy of the worst kind, to call them narrow minded.
