Educating in additional languages

Teaching people foreign or other national languages.
Bi- or multi-lingual education gives the mind different structures and intellectual possibilities. Bilingual children realize earlier than monolingual children that there is no intrinsic relationship between the name given to things and the things themselves. A dog is also 'chien' or 'hond'. This separation between sound and meaning is a crucial step in the child's intellectual development.
Counter Claim:
A single universal language should be taught.
