Charles Sanders Peirce Quote

In those sciences of measurement which are the least subject to error — meteorology, geodesy, and metrical astronomy — no man of self-respect ever now states his results, without affixing to it its probable error; and if this practice is not followed in other sciences it is because in those the probable errors are too vast to be estimated.
