JzG, what do you think you're doing by saying that I find your answer unacceptable because it conflicts with my opinions? What opinions? What do you imagine I believe? I'm not a supporter of Sheldrake's views at all, if that is what you imagine. Your response is too vague to be helpful, and as such of course it isn't valid. The comments by the Red Pen of Doom are barely coherent and unfortunately simply illustrate the low level of discourse on Wikipedia.
