The trouble with joined-up thinking is that there are so many different ways of joining things (thoughts) up. I find it attractive, as in a really persuasive speech, but increasingly unsatisfactory.
So I'm going to try the way of the desultory. A desultor was an equestrian acrobat who entertained the crowd by leaping from one swiftly moving horse to another. That's what I'm going to do in this blog - to jump randomly from one thing to another. One of the fears I shall have to face down in doing this is the fear of being, or seeming, disconnected or superficial. Still, no more detailed explanation or it rather defeats the object.
