One also recommends Esperanto as a core element in courses for the linguistic sensitization of students. "We assert that the difficulty of the ethnic languages always will present obstacles to many students, who nevertheless would profit from the knowledge of a second language. We are a movement for effective language instruction." The Esperanto community is one of the few worldwide linguistic communities whose members are, without exception, bi- or multilingual. Each member of the community accepted the task of learning at least one foreign language to a communicative degree. In multiple cases this leads to the knowledge and love of several languages and generally to broader personal horizons. "We assert that the speakers of all languages, large and small, should have a real opportunity to learn a second language to a high communicative level. We are a movement for the provision of that opportunity." The unequal distribution of power between languages is a recipe for permanent language insecurity, or straightforward linguistic suppression, in a large part of the world's population. In the Esperanto community, the speakers of a language, large or small, official or nonofficial, meet on neutral terms, thanks to a reciprocated will to compromise. This equilibrium between linguistic rights and responsibilities provides a precedent for developing and evaluating other solutions to language inequalities and conflict. "We assert that the vast variations in power among languages undermines the guarantees, expressed in so many international documents, of equal treatment without discrimination of languages. We are a movement for linguistic rights""." The national governments tend to consider the grand diversification of world languages as barriers to communication and development. For the Esperanto community, however, linguistic diversity is a constant and indispensable source of enrichment. Therefore, every language, like every living thing, is inherently valuable and worthy of protection and support. "We assert that policies of communication and development, if not based on respect and support for all languages, condemn to extinction the majority of the word's languages. We are a movement for linguistic diversity." Every language liberates and imprisons its speakers, giving to them the power to communicate among themselves while barring them from communication with others. Planned as a universal communications tool, Esperanto is one of the largest functioning projects of human emancipation or projects to enable every human to participate as an individual in the human community, with secure roots in their local culture and linguistic identity, while not being limited by it. "We assert that the exclusive use of national languages inevitably raises barriers to the freedoms of expression, communication, and association. We are a movement for human emancipation."
