Answer 1

Development and Mobility

The discussion in The Autocrat of the Breakfast-Table that precedes “The Chambered Nautilus” focuses on the various stages of life and the importance of making progress by moving on from what one previously knew. In a sense, the poem is an elaboration on this idea, because it focuses on the concept of sealing off one's previous boundaries to create new and larger spaces in which to live and develop.
