In this poem Shelley desribes the inconstancy of human emotions and aspirations, even of life itself. To what extent is the sentiment in this poem a comment on poetry's potential to transform the individual and the community?

Certainly the poem's title gives us a sense of this. The title "Mutability" gives us the sense of remoulding or transformation. Shelley talks about the human condition and how it is a subjective condition. Like clouds, the human condition is fleeting and apt to change and evolve. There is also the sense that transformation of the human condition is inevitable. No matter how hard we try to cling to past experiences, "no second motion brings", we cannot relive what once was.
