There are times and places where it’s good to aim for perfection. Mainly in the manufacture of machines and technologies, especially where precision makes a big difference to performance.
But in the natural world, in Life, in living as a human, perfection isn’t such an easy concept to define or achieve.
What’s a perfect tree? A perfect person? A perfect day?
In Japanese aesthetic, captured in the concept of wabi sabi, what might be termed imperfection is seen as beautiful.
Think of pottery made by human hand. It tends to look different from that mass produced by machines in a factory.
This photo is of a “dry stane dyke”, a common sight in Scotland, and almost always beautiful. The stones are carefully placed on top each other but they are all different shapes and the wind can blow through the spaces between them. There is no cement or mortar. They often get covered in moss which makes them somewhat more beautiful but you can’t manufacture that.
They are even beautiful many years later when they fall down.
