is a metaphorical extension of this notion of a message from a sender to a recipient. In English, the meaning "something which stands for something else" was first recorded in 1590, in Edmund Spenser's Faerie Queene. Concepts and definitions Symbols are a means of complex communication that often can have multiple levels of meaning. Symbols are the basis of all human understanding and serve as vehicles of conception for all human knowledge. Symbols facilitate understanding of the world in which we live, thus serving as the grounds upon which we make judgments. In this way, people use symbols not only to make sense of the world around them, but also to identify and cooperate in society through constitutive rhetoric. Human cultures use symbols to express specific ideologies and social structures and to represent aspects of their specific culture. Thus, symbols carry meanings that depend upon one's cultural background. As a result, the meaning of a symbol is not inherent in the symbol itself but is culturally learned. Heinrich Zimmer gives a concise overview of the nature, and perennial relevance, of symbols. In the book Signs and Symbols, it is stated that {{quote|A symbol ... is a visual image or sign representing an idea -- a deeper indicator of universal truth.}} Symbols and semiotics Semiotics is the study of signs, symbols, and signification as communicative behavior. Semiotics studies focus on the relationship of the signifier and the signified, also taking into account the interpretation of visual cues, body language, sound, and other contextual clues. Semiotics is linked with linguistics and psychology. Semioticians not only study what a symbol implies but also how it got its meaning and how it functions to make meaning in society. Symbols allow the human brain continuously to create meaning using sensory input and decode symbols through both denotation and connotation. Psychoanalysis, rhetoric, and archetypes An alternative definition of symbol, distinguishing it from the term sign was proposed by Swiss psychoanalyst Carl Jung. In his studies on what is now called Jungian archetypes, a sign stands for something known, as a word stands for its referent. He contrasted a sign with a symbol: something that is unknown and that cannot be made clear or precise. An example of a symbol in this sense is Christ as a symbol of the archetype called self. Kenneth Burke described Homo sapiens as a "symbol-using, symbol making, and symbol misusing animal"
