What is a symbol? Here is my definition:
A symbol is something that represents a conceptI believe that behind every symbol is a concept. Symbols are portable concepts. In this regard, symbols are useful for communicating efficiently and making propositions.
Although many symbols are completely abstract (such as the peace sign), there are some symbols that have a physical relation to the meaning. For example, imagine the up arrow symbol. This symbol resembles the thing it represents. In this regard, the up arrow symbol is not abstract.
