Well over five thousand languages are known to exist or to have existed in the world, but hundreds of these are no longer living languages used by speakers and speech communities in their day-to-day activities and lives. Some of them lead a pseudolife as revered monuments of the past which still have some restricted and specialised roles to play today, such as Latin, Ancient Greek, Church Slavonic and others, but most of them are of interest and concern only to a small group of linguists, historians and some other experts who look at the past. Many languages have disappeared without being known to us in any great detail, with only some fragmentary materials in them - written or noted down by speakers or observers of them hundreds or even thousands of years ago - at our disposal to give us some idea as to what those languages were like. Others have disappeared without even that scanty information about their nature being available to us; only their names are known from historical records, or perhaps some remarks were written down by someone many years ago and were preserved over the ages to tell us something about some special features of such a language or such languages and who and what kind of people their speakers were. Many other languages, certainly a much larger number than the dead languages about which we know something, have disappeared without our knowing anything of or about them.

Africa, along with Asia, is the continent with the highest number of ‘living’ indigenous languages. European languages, mainly English, French and Portuguese, have spread throughout all African nations during the last 200 years; however, until today, the use of these ‘foreign’ languages has been mostly restricted to certain domains, such as higher education, politics and business, and also to a relatively small number of people. According to Scotton (1982: 68) only 10 per cent or less of the rural African population have a considerable competence in the imported languages, even though these are in many instances the official languages of their home countries. African vernaculars are generally not in danger of being replaced by European languages. However, we observe a diminishing use of African vernaculars, not only in an increasing number of domains, but also with regard to the absolute number of indigenous languages; that means, in short, that linguistic vitality and variety on the African continent is decreasing.

At the beginning of the sixteenth century, in the lands that are now the United States (the forty-eight contiguous states, Alaska and Hawaii), there must have been many hundreds of distinct languages. Fewer than two hundred remain, and the future of these is decidedly insecure, even where the remoteness of the location (in the case of Inuit in Northern Alaska) or the large size of the speech community (in the case of Navajo in the Southwest) might seem to protect the community from language loss. Yet even this vastly reduced reservoir of linguistic diversity constitutes one of the great treasures of humanity, an enormous storehouse of expressive power and profound understandings of the universe. The loss of the hundreds of languages that have already passed into history is an intellectual catastrophe in every way comparable in magnitude to the ecological catastrophe we face today as the earth's tropical forests are swept by fire. Each language still spoken is fundamental to the personal, social and - a key term in the discourse of indigenous peoples - spiritual identity of its speakers. They know that without these languages they would be less than they are, and they are engaged in the most urgent struggles to protect their linguistic heritage. The goal of this paper is to review the contexts and practices of this struggle, in the hope that people everywhere will support it.

About 130 languages are currently spoken in the USSR. These languages differ considerably in their numbers of speakers, social status, scope and viability. Our primary interest in this paper will be with those languages that are in extreme danger of extinction in the near future.

Every human community creates its own representation of its surrounding world and of the men who constitute that world. It sets out in an orderly fashion the raison d’être of social and cultural organisation, it ritualises the ties between men and their relationship with their environment. Man creates the world while the world creates man, through a relationship which varies with each society; ethnography shows us innumerable versions. Human cultures consist of symbols. It is always a matter of reducing the world to the human factor, but in line with a social imaginary quantity specific to a particular group, which is itself the tributary of its past and the possible influence of other groups.

The time has come to rehabilitate the history of ideas in French literary studies, primarily because we should retreat from the disrepute attached to all universalising approaches to the real in the name of an ever-increasing subdivision of knowledge which proves on occasion to be shortsighted or stultifying.
