Symbology


A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. Symbols allow people to go beyond what is known or seen by creating linkages between otherwise very different concepts and experiences. All communication (and data processing) is achieved through the use of symbols. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to convey other ideas and beliefs. For example, a red octagon may be a symbol for "STOP". On a map, a blue line might represent a river. Numerals are symbols for numbers. Alphabetic letters may be symbols for sounds. Personal names are symbols representing individuals. A red rose may symbolize love and compassion. The variable 'x', in a mathematical equation, may symbolize the position of a particle in space.

In cartography, an organized collection of symbols forms a legend for a map.

The word derives from the Greek symbolon (σύμβολον) meaning token or watchword. It is an amalgam of syn- "together" + bole "a throwing, a casting, the stroke of a missile, bolt, beam." The sense evolution in Greek is from "throwing things together" to "contrasting" to "comparing" to "token used in comparisons to determine if something is genuine." Hence, "outward sign" of something. The meaning "something which stands for something else" was first recorded in 1590, in Edmund Spenser's Faerie Queene.

In considering the effect of a symbol on the psyche, in his seminal essay The Symbol without Meaning Joseph Campbell proposes the following definition: A symbol is an energy evoking, and directing, agent.

Later, expanding on what he means by this definition Campbell says:

Heinrich Zimmer gives a concise overview of the nature, and perennial relevance, of symbols.

In the book Signs and Symbols, it is stated that A symbol ... is a visual image or sign representing an idea -- a deeper indicator of a universal truth.

Symbols are a means of complex communication that often can have multiple levels of meaning. This separates symbols from signs, as signs have only one meaning.
