Fear: a distressing emotion aroused by impending danger, evil, pain, etc., whether the threat is real or imagined; the feeling or condition of being afraid.
Robert Frost wrote ‘Desert Places’ in 1936 and it ends saying:
They cannot scare me with their empty spaces
Between stars –on stars where no human race is.
I have it in me so much nearer home
To scare myself with my own desert places.
Change: to become different
In ‘The Black Cottage’ Robert Frost writes as a priest and says:
For, dear me, why abandon a belief
Merely because it ceases to be true.
Cling to it long enough, and not a doubt
It will turn true again, for so
Most of the change we think we see in life
Is due to truths
being in and out of favour.
