[Thomas Forster]

Vaughan, I don't think you have to go to other planets to get instances of the 
kind you want.  Just the other side of a tunnel from the island i'm on
lies a land inhabited by a stange tribe whose philosophy, views on
lierary theory etc, etc, are radically different from those on this island
but whose mathematics is very similar...
