Quote from ‘C.S.P.'s Lowell Lectures of 1903 2nd Draught of 3rd Lecture’


This element of our daily & hourly experience, the element of the conformity of fact to thought, – this element whose being such as it is consists in this that it has such reference to an object independent of it as to bring a third thing (the interpretation) into the same triadic relation to that same object, – this character of a sign, the being an exponent of thought, is what I call the element of Thirdness in the phenomenon.
