Semiotics - Terminology

Terminology

The term, which was spelled semeiotics, derives from the Greek σημειωτικός, (sēmeiōtikos), "observant of signs" (from σημεῖον - sēmeion, "a sign, a mark") and it was first used in English by Henry Stubbes in a very precise sense to denote the branch of medical science relating to the interpretation of signs. John Locke used the terms semeiotike and semeiotics in Book 4, Chapter 21 of An Essay Concerning Human Understanding (1690). Here he explains how science can be divided into three parts:

All that can fall within the compass of human understanding, being either, first, the nature of things, as they are in themselves, their relations, and their manner of operation: or, secondly, that which man himself ought to do, as a rational and voluntary agent, for the attainment of any end, especially happiness: or, thirdly, the ways and means whereby the knowledge of both the one and the other of these is attained and communicated; I think science may be divided properly into these three sorts. —Locke, 1823/1963, p. 174

Locke then elaborates on the nature of this third category, naming it Σημειωτικη (Semeiotike) and explaining it as "the doctrine of signs" in the following terms:

Nor is there any thing to be relied upon in Physick, but an exact knowledge of medicinal physiology (founded on observation, not principles), semiotics, method of curing, and tried (not excogitated, not commanding) medicines. —Locke, 1823/1963, 4.21.4, p. 175

In the nineteenth century, Charles Sanders Peirce defined what he termed "semiotic" (which he sometimes spelled as "semeiotic") as the "quasi-necessary, or formal doctrine of signs", which abstracts "what must be the characters of all signs used by...an intelligence capable of learning by experience", and which is philosophical logic pursued in terms of signs and sign processes. Charles Morris followed Peirce in using the term "semiotic" and in extending the discipline beyond human communication to animal learning and use of signals.

Ferdinand de Saussure, however, founded his semiotics, which he called semiology, in the social sciences:

It is... possible to conceive of a science which studies the role of signs as part of social life. It would form part of social psychology, and hence of general psychology. We shall call it semiology (from the Greek semeîon, 'sign'). It would investigate the nature of signs and the laws governing them. Since it does not yet exist, one cannot say for certain that it will exist. But it has a right to exist, a place ready for it in advance. Linguistics is only one branch of this general science. The laws which semiology will discover will be laws applicable in linguistics, and linguistics will thus be assigned to a clearly defined place in the field of human knowledge. —Cited in Chandler's "Semiotics For Beginners", Introduction.
