If eyes are windows to the soul, then windows are eyes to the world. It is through them that we see what goes on beyond the house and family. If they are old, scratched, unable to open smoothly; if their vapor lock is broken — what will we then make of the world?
Probably much the same as if they were crystal clear, in all truth. After all, we aren't hermits hibernating in this house. We leave and return to it every day. Our view of the outside isn't limited by what we see from the inside.
And yet, as I look out a pair of brand new windows, the world is new born. The recent arrivals slide up and down in their casements. They are so clear and unsullied that they are invisible. May's green grass and leaves explode outside them.
For years we have been silting up and clouding over, but the transformation has been so subtle and gradual that we haven't noticed. Now that the old windows are out and the news ones in the scales are off. We no longer see through a glass darkly.
