Semiotics
Semiotics is the study of signs and sign systems — how meaning is created, communicated, and interpreted through symbols, images, gestures, and language across all forms of human expression.
Overview
Saussure's insight that signs are arbitrary conventions established the foundational principle that the relationship between signifier and signified is culturally determined rather than natural, revolutionizing linguistics and philosophy of language. Peirce developed a parallel and more comprehensive taxonomy of signs — icons, indexes, and symbols — that extended semiotic analysis beyond language to all forms of representation and established the field as an independent discipline.
Why it matters
Semiotics has shaped literary criticism, cultural studies, media theory, and design — revealing how symbols encode and transmit power, ideology, and identity in ways invisible to unreflective participants. Its influence extends to biology through biosemiotics, which examines how organisms interpret environmental signs and how genetic information is 'read' by cellular machinery, connecting semiotic theory to the biology of information processing.
