The writer is, first, rejecting Macbeth's depressing view of our human predicament on the basis that it applies to his specific situation only (Macbeth's frustration in not achieving his egotistic ambition to become King). Secondly, the writer thinks we can experience satisfaction (apparently fulfillment) from realizing a sense of unity between the world and ourselves. That sense of unity, in the writer's opinion, is the key to avoiding the kind of alienation and isolation that Macbeth experiences.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
