Conscience? I'd have to disagree here. "Conscience" is usually a restraining/compelling force to keep us from doing what we know is wrong or to prod us to do what's right. It may have something to do with fear, either of consequences or of seeming socially unfit (Peer pressure). Mental telepathy is a whole 'nother thing, in my opinion. While I would not expect to use it for making Dental appointments, I might not be surprised to find myself knowing that a friend or offspring is in distress. If I'm out hunting mastodons such a means of communication could be very handy indeed. What has survival value persists, even in our modern concrete jungles and interstate highway savannas. It helps me keep out of the way of the saber-toothed semis and law enforcement officials. wink
