Semeiotic

&#9758; This page belongs to resource collections on Logic and Inquiry.

Semeiotic is one of the terms that Charles Sanders Peirce used to describe his theory of triadic sign relations, along with semiotic and the plural variants of both terms. The form semeiotic is often used to distinguish Peirce's theory, since it is less often used by other writers to denote their particular approaches to the subject.

Types of signs
There are three principal ways that a sign can denote its objects. These are usually described as kinds, species, or types of signs, but it is important to recognize that these are not ontological species, that is, they are not mutually exclusive features of description, since the same thing can be a sign in several different ways.

Beginning very roughly, the three main ways of being a sign can be described as follows:


 * An icon is a sign that denotes its objects by virtue of a quality that it shares with its objects.


 * An index is a sign that denotes its objects by virtue of an existential connection that it has with its objects.


 * A symbol is a sign that denotes its objects solely by virtue of the fact that it is interpreted to do so.

One of Peirce's early delineations of the three types of signs is still quite useful as a first approach to understanding their differences and their relationships to each other:
