No man had ever a point of pride that was not injurious to him, so no man had ever a defect that was not somewhere made useful to him.
Emerson argues that qualities commonly regarded as strengths or weaknesses can have unexpected consequences. Pride in a particular ability may become harmful if it leads to overconfidence, rigidity or excessive dependence on that strength. Conversely, a limitation may encourage someone to develop other capacities, habits or forms of judgement that later prove useful.
Within Compensation, the statement illustrates Emerson’s broader belief that advantages and disadvantages often contain counterbalancing effects. He does not mean that every defect is beneficial in itself, or that every source of pride is necessarily damaging. Rather, he challenges simple judgements about character by showing how personal qualities can produce mixed results. The quotation therefore encourages a more balanced view of strengths and weaknesses, recognising that apparent advantages may carry costs while apparent disadvantages can sometimes contribute to growth, resilience or adaptation.
