My apologies for my late reply as I have been in hospital for the last few days.
I assume when you say authentic conversation we are talking with the interests of both parties at hand or more parties if it is a conversation between more than two people. Or maybe you are saying people that are actually interested in what the other people are saying to see what develops from it, it being the conversation - instead of talking past each other. Regarding high minded thinking - I think we would lose a little of our essence if all that communication involved was high minded thinking. Obviously it is important to incorporate high minded thinking into adult conversation and to a lesser extent those who are younger, else where would we be. Soooo, I agree that high minded thinking needs to be incorporated into everyday conversation, for sure, but we also need to trust ourselves and let our hair down so to speak and be a little relaxed - incidentally you would not need to be consciously aware of your high minded thinking as it seems to come natural to you - perhaps meditate on it occasionally is what the doctor should order.
Assuming that you are referring to the common agenda of the human race then there is no common agenda to easily speak of - that is to say that there is a common agenda that has become so watered down that it is nearly impossible to detect it. I might have to make a thread about this and similar subjects in the future.
It seems to me that the current common agenda is more about survival for the less rich and bragging about life for the more rich.
