"I have, in some cases, adopted his views either wholly or in part. In a few instances he does not really contest what I have said, but notices something I have left unsaid…Hence the number of points on which we differ is now considerably reduced; and I think a further reduction might have been made if he could have seen his way, in like manner, to adopting views from me." W. W. Skeat, from the preface to the 2nd Edition [Walter Skeat laid the foundation for the Oxford English Dictionary. Without Skeat there would not have been an OED]
"What we have here is a failure communicate..." who hasn't heard that memorable line from Cool Hand Luke? As relevant today as ever, communication requires effort from both parties. Mostly, communication requires that each party be willing to listen to the other. Easy enough for some, to use a public podium to lecture, harangue, lie, whatever...and so totally dominate conversation that any other party's voice is drowned out. That isn't communication.
