Article 4
1. This Declaration considers that persons who move to and settle in the territory of another language community have the right and the duty to maintain an attitude of integration towards this community. This term is understood to mean an additional socialization of such persons in such a way that they may preserve their original cultural characteristics while sharing with the society in which they have settled sufficient references, values and forms of behaviour to enable them to function socially without greater difficulties than those experienced by members of the host community.

2. This Declaration considers, on the other hand, that assimilation, a term which is understood to mean acculturation in the host society, in such a way that the original cultural characteristics are replaced by the references, values and forms of behaviour of the host society, must on no account be forced or induced and can only be the result of an entirely free decision.
