Hi Everyone, I wonder if you can help me, I am searching for a story I read a few years ago. It was a short story and was about two men who discover some sort of secret to improving their intelligence exponentially. As the story proceeds they come into conflict and through a series of encounters and using various increasingly complex means to affect one another one defeats the other. I think there is some reference to a concept something like verbally transmitted "virus" that infects the mind or something in that area. My recollection is quite vague but I remember it being excellent and would love to find it again. Can anyone help? Many thanks RezD Edit: My Brain is telling me that it may be A Greg Bear Short Story but this is by no means certain.
