The concept of symbol (a word that derives from Latin simbŏlum) serves to represent, in some way, a idea that can be perceived from the senses and that presents features linked to a convention accepted at the social level. The symbol has no similarities or a contiguity link with its meaning, but only establishes a conventional relationship .
By these characteristics, the symbol can be differentiated from icon (a sign that replaces the object by similarity) and index or indicator (which is characterized by causality). The symbol allows to externalize or reflect a thought or concept from a social convention (of character arbitrary ).
For example: "The hippie movement of the 1960s was identified with the symbol of peace", "The cross is the main Christian symbol", "Yesterday I saw a documentary explaining the emergence of the ying and yang symbol".
In everyday language, it is understood as a symbol to what represents and embodies certain values. This way you can talk about National symbols (such as a flag or a shield), which are the standard of a country .
In the same way, we cannot ignore the existence of symbols within the religious sphere. Thus, for example, in ancient Egypt it was common to use hieroglyphic writing to represent and symbolize not only their deities but also various cultural or social aspects.
And that without forgetting that in the case of the Christian religion many have been the symbols that have developed and had throughout its history. In this way, it is necessary to emphasize the important value that those had in their origins, at the moment in which any person who professed said faith was persecuted to be killed.
Thus, at that time the symbols were used as methods to be recognized among Christians. One way to do it, for example, was by representing rings that were represented in the catacombs, the underground galleries that were used as burial sites.
A sex symbol on the other hand it is a person which, for most of society, is attractive and sensual. The concept began to be used in the first decade of twentieth century and currently includes celebrities like Angelina Jolie , Megan fox , Leonardo Dicaprio and Brad Pitt .
For the linguistics , a symbol is a kind of scientific or technical abbreviation which is based on signs outside the alphabet or by characters and which, unlike traditional abbreviations, are not accompanied by a period. $ it is the symbol of peso or dollar while N It is the north symbol.
In addition to all of the above, it should be stressed that in recent years a book that uses the term that occupies us as an integral part of its title has acquired special prominence. We are referring to the novel "The Lost Symbol" published in 2009 by the American writer Dan Brown.
This author, after the controversy raised with his work "The Da Vinci Code" that called into question the pillars of the Christian Church, presented this narrative where symbology expert Robert Langdon must face an investigation of Masonic secrets that can wobble The world of the 21st century.
