We see a blue sky where nothing blue exists – remember, the atmosphere isn’t blue at all, but only appears blue to us because of the phenomenon of refraction.
And that blue sky we see is vast & glorious.
The act is automatic – the translation of light by sight.
It is innocent, selfish and necessary. Naïve, and yet a great effort.
To find happiness and make beauty in our daunting contemporary reality is a tremendous act of will.
