Abstract:Brain text is not a language but a kind of text saved in human brain. In general, brain text is presented through oral expression with human vocal organs and through writing symbols,both of which are the most common methods of information exchange and communication in the human world. Brain text will generate language whenever it is transformed into sound, and it will become written text after it is written down in symbols. Language can be converted into text and vice versa. However,language or written text is the embodiment of brain text. Language all comes from and is the vocal form of brain text. Thus, language is not a tool but rather a method of communication.
