Quote from ‘C.S.P.'s Lowell Lectures of 1903 2nd Draught of 3rd Lecture’
The third class of signs are Symbols, which not only, like all signs, function as such in being interpreted as such, but further have for their special significant character merely the certainty, based on some habit, natural disposition, or convention, that they will be understood in certain ways.
