Abstract
The signs of a language cut out the phenomena in a special way, and each sign highlights the part of a phenomenon. This issue arises from the voluntary nature of the signs and the basis for the formation of the identity and common understanding of a group of the world. Accordingly, the users of a language see the world from an all-encompassing perspective, like their fellow speakers. Therefore, the user of a language, before he can learn and think about the native language of his country, if he is assigned to learn a foreign language, will know a part of the world with the sign parts of that foreign language and may suffer from identity disorders. This, in a general approach, also accelerates the process of forming a forty-piece identity. Accordingly, in this article, we try to discuss the teaching of foreign languages to children, which has become ubiquitous in our time, with a delay on the voluntary nature of signs and the place of language in the formation of identity. Research shows that teaching children foreign languages disrupts their world-images and deprives children of the ability to think soundly in the national language. Such a child sees a part of the world through the lens of a foreign language he has learned and another part with the help of the official language of his country, and becomes an example of the phenomenon of "forty-piece identity".
