Illusion

The material world around us consists of tiny particles far away from each other, and empty space in between. And those particles are made of even smaller particles, which in turn are made of nothing.

the world around seems ridiculous 

So teaches us physics.

The social world around us is made of conventions, habits and significances based on themselves. The mental world is mostly unknown.

Doesn't sound too rational. And quite right: the world around us seems both irrational and ridiculous. So let's make the most of it and create art that lets us see through the imaginary rationality of life. 

It might help us smile. It might help us relax.
