To the memory of my wife the metaphysician
The word ICON (< L icon, < Gk ∊iκώv ‘likeness, image, portrait, similitude, semblance‘) has entered the parlance of linguists and philosophers as a technical term, not to speak of anthropologists and other students of culture, especially those who have some cognizance of the theory of signs (semiotics) and of its modern founder, Charles Sanders Peirce (1839–1914). In Peirce's sign theory an icon is a member of his most well-known trichotomy of icon/index/symbol, by which he meant to designate the mutable relations between a SIGN and its OBJECT. Peirce's earliest published mention of this trichotomy is from 1885 (EP 1:225).
