Emerson rejects the idea that the individual has a final or fixed boundary. His language of walls and circumferences develops the central image of Circles, in which every apparent limit can be surrounded by a wider one. The self is therefore presented as capable of further thought, experience and development rather than as something permanently enclosed by its present condition.

Within the essay, this claim expresses Emerson’s broader Transcendentalist belief in continual expansion of consciousness and understanding. What appears to define a person at one moment may later prove temporary as new knowledge or experience changes their perspective. The statement is metaphysical rather than literal: Emerson is not denying physical limits, but challenging the assumption that intellectual and spiritual development has a fixed endpoint. The quotation therefore presents human identity as open-ended, with each established boundary capable of being reconsidered or surpassed.
