Definition / description
The study of signs in general, their use in language and reasoning, and their relationships to the world, to the agents who use them, and to each other. It was developed independently by the logician Charles Sanders Peirce, who called it semeiotic, and by the linguist Ferdinand de Saussure, who called it sémiologie; other variants are the terms semiotics and semiology. Peirce developed semiotic into a rich, highly nuanced foundation for formal ontology, starting with three metalevel categories, which he called Firstness, Secondness, and Thirdness. Specialized examples of these categories include Aristotle's triad of Inherence, Directedness, and Containment in Figure 1 and the triad of Independent, Relative, and Mediating in Figure 6. One of Peirce's most famous examples is the triad of Icon, Index, and Symbol.
