Rowan Williams, in his Presidential Address, postulates that our Anglican troubles are caused by seeing in only two dimensions; so, put on those polarised lenses, stare at the screen, and prepare to be amazed:

Earlier I mentioned ‘three-dimensionality’.  Seeing something in three dimensions is seeing that I can’t see everything at once: what’s in front of me is not just the surface I see in this particular moment.  So seeing in three dimensions requires us to take time with what we see.

Until Rowan attempted to explain it, I thought I understood seeing in three dimensions; never mind, if Rowan is seeing that I can’t see everything at once it’s probably only because he forgot his 3D glasses. And, of course, seeing in three dimensions requires us to take time with what we see means we have to take time into consideration and see in four dimensions, which will require a tinfoil hat in addition to the 3D glasses  – see?
