  1. Relations between Signs and SymbolsIn the Light of Peircian Philosophy Gennaro Auletta Pontificia Universitas Gregoriana

  2. Peirce’s semiotic studies • Peirce has given rise to this important field, which is very relevant for living beings (including humans). • However, semiotics cannot be applied to the physical world. We need here the concept of information, which was formulated much later. • For humans, on the contrary, signs are insufficient, and we also need the concept of symbols.

  3. What is a Sign? • A sign is something which stands to somebody for something in some respect or capacity [CP: 2.228 and 1.540; 1868b: 223]. • Signs have an iconic function and an indexical function. (1) The iconic function is the respect or capacity, whereas (2) the indexical function is the standing-for aspect [see CP: 2.304].

  4. Cherry’s and Morris’ Triangle

  5. Ethology Studies Showed 3 Forms • Reference (Marler and Green’s indexical reference that is not an active production of a sign), • Addressing (deictic semiosis in Marler and Green’s language that also covers other contextual forms of communication), which is basic to all form of communication, and • Purposivity, which is the active transmission of a sign as sign of something to a partner who can understand it as a sign of this something.

  6. First Semiotic Mode (Reference)

  7. Second Semiotic Mode (Addressing)

  8. Third Semiotic Mode (Purposivity)

  9. Information is codified A code is a set of physical objects or states that • are functionally elementary and therefore play the role of codifying units, • are alternative (each use of one of them implies a choice), and • can be combined to form clusters so that the whole is functionally independent from the units.

  10. Let us apply this to Information • Source of variety. • Mutual information. • Selection.

  11. General Scheme

  12. Differences BetweenInformation and Sign • Information is codified, signs do not. • A sign is referential and therefore stands for something else, whereas information stands for nothing else. • A sign can be taken as a representation (an icon) of something else (given the standing-for relation), while information does not.

  13. Symbols • Symbols are codified, like information. • Symbols do not have an iconic aspect, like information (they invite the partners to provide one). • Symbols are referential, like signs.

  14. Social Aspect • A symbol must be shared in order to be understood, that is, it consists in an intentional process (a joint, non-physical, social action of at least two partners toward a third party), • And, for this reason, symbols are conventional.

  15. Double referential relation:Sender-Symbol-Referent and Receiver-Symbol-Icon
