Are not too hard to comprehend
Until you try to certainly
Assert it to some certain end.
All of a sudden there arise
A thousand little arguments
Each full of tiny hows and whys
For you to pen, each in its fence.
It's like a coastline, and its length:
So easy on a map to see
But measured closely, past the strength
Of any true cartography.
The moment that you try to claim
A certainty, you lose your aim.
