Emerson argues that ability develops through action. People do not necessarily acquire the power to perform a difficult task before attempting it; rather, the effort of doing the work helps create the strength, skill and confidence required. His formulation therefore challenges the idea that readiness must always come before action.

Within Compensation, the statement reflects Emerson’s broader belief that actions carry corresponding consequences. Effort produces experience and capacity, while inaction leaves potential undeveloped. His reference to a “law of nature” is philosophical rather than scientific: he is presenting a general principle about human development. The quotation links power with participation, suggesting that competence is not simply possessed but cultivated through practice. In this sense, Emerson presents action as both a test of existing ability and a means by which greater ability is acquired.
