Most of us are blind in certain areas of life: some are blind in music, some in Maths, some in philosophy.
Being blind means of course that we don’t know we’re blind.
What’s the cure?
I figure the only cure for this is the acceptance of our fallibility: that although we believe very much in our view, it’s possible that we are wrong.
Only when we haven’t closed the door may sunlight one day reach our mind.
(I always see the light, of course!)
