While reading the Dune series of books I've been pondering the problems which must attend (conceptually) on ruling an entire world. Principally, how does one holdtogether an entire planet when most human politicians seem incapable of holding together any civilisation larger than Wigan.
Doing some wider reading I ran across a theory that communications define the size of a civilisation. Roads, originally, and rivers. They carried ideas by person and by post. Then ideas moved to the printed book, and this allowed them to move slightly faster and to establish some permanence. Then you had the far sending of communications via signal flag, telegraph, telephone, and radio. As these got bigger so too did teh Empires and civilisations you could maintain with them.
With me so far?
But it occurred to me that sending and receiving the idea is only part of the picture. I started lookng at the psychology of communications, and identified the obvious barrier, which is language. But again, this only explains so much. Until I got to the point in the psychology book discussing the theory that there is an abstract representation underpinning language, and that representation relies upon context. Context at a local level means that when I say "Meet you for tea at 1600" you can understand it is going to involve us being in proximity in the late afternoon. Context adds information, such as the knowledge that you can expect more than just hot leaf water; perhaps biscuits. But in other ways it means that I am not insulting you, or that I am insulting you. For example if I said that to the Queen it would be deliberately over-familiar.
It occurred to me that we have exhausted the technological barriers to sending and receiving anywhere on the world. What we lack is advances in communicating or sharing context.
Or was I simply in the bath too long?
