Harry Haller believes life consists of constant destructions of the self. No matter where he goes it is pointless because the cycle of sufferings will continue to replay.
“At the end of the road there was no peace or quiet―but forever destroying the self, in order to renew the self” (Hesse 69)

What changes in the end of the story that makes him so much more hopeful? He’s satisfied with the tragedy of his life. He notes “A glimpse of its meaning had stirred my reason” (117); noting the change. What is different this time?

Before he was denying the truth to the professor’s views noting how wars are continues and even science is a constant “shattering of foundations” (78).
