…don’t you understand that we need to be childish in order to understand? Only a child sees things with perfect clarity, because it hasn’t developed all those filters which prevent us from seeing things that we don’t expect to see.

So what of this horse, then, that actually held opinions, and was sceptical about things? Unusual behaviour for a horse, wasn’t it? An unusual horse perhaps?

No. Although it was certainly a handsome and well-built example of its species, it was none the less a perfectly ordinary horse, such as convergent evolution has produced in many of the places that life is to be found. They have always understood a great deal more than they let on. It is difficult to be sat on all day, every day, by some other creature, without forming an opinion on them.

On the other hand, it is perfectly possible to sit all day, every day, on top of another creature and not have the slightest thought about them whatsoever.

If the Universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don’t. It’s like a human body, you see. A few cuts and bruises here and there don’t hurt it. Not even major surgery if it’s done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make.
