Around 7,500 spoken and signed languages are used worldwide today. Yet this extraordinary diversity may represent only a fraction of the linguistic richness humanity once possessed. A new modeling study published in Science suggests language diversity reached a forgotten golden age between 1,000 and 3,000 years ago, when tens of thousands of languages may have coexisted. What followed was a dramatic decline that appears to have begun long before European colonial expansion…….Continue reading….

As an object of linguistic study, “language” has two primary meanings: an abstract concept, and a specific linguistic system, e.g. “French”. The Swiss linguist Ferdinand de Saussure, who defined the modern discipline of linguistics, first explicitly formulated the distinction using the French word langage for language as a concept, langue as a specific instance of a language system, and parole for the concrete use of speech in a particular language.

When speaking of language as a general concept, definitions can be used which stress different aspects of the phenomenon. These definitions also entail different approaches and understandings of language, and they also inform different and often incompatible schools of linguistic theory. Debates about the nature and origin of language go back to the ancient world.

Greek philosophers such as Gorgias and Plato debated the relation between words, concepts and reality. Gorgias argued that language could represent neither the objective experience nor human experience, and that communication and truth were therefore impossible. Plato maintained that communication is possible because language represents ideas and concepts that exist independently of, and prior to, language.

During the Enlightenment and its debates about human origins, it became fashionable to speculate about the origin of language. Thinkers such as Rousseau and Johann Gottfried Herder argued that language had originated in the instinctive expression of emotions, and that it was originally closer to music and poetry than to the logical expression of rational thought. Rationalist philosophers such as Kant and René Descartes held the opposite view.

Around the turn of the 20th century, thinkers began to wonder about the role of language in shaping our experiences of the world – asking whether language simply reflects the objective structure of the world, or whether it creates concepts that in turn impose structure on our experience of the objective world. This led to the question of whether philosophical problems are really firstly linguistic problems.

The resurgence of the view that language plays a significant role in the creation and circulation of concepts, and that the study of philosophy is essentially the study of language, is associated with what has been called the linguistic turn and philosophers such as Wittgenstein in 20th-century philosophy. These debates about language in relation to meaning and reference, cognition and consciousness remain active today.

One definition sees language primarily as the mental faculty that allows humans to undertake linguistic behaviour: to learn languages and to produce and understand utterances. This definition stresses the universality of language to all humans, and it emphasizes the biological basis for the human capacity for language as a unique development of the human brain.

Proponents of the view that the drive to language acquisition is innate in humans argue that this is supported by the fact that all cognitively normal children raised in an environment where language is accessible will acquire language without formal instruction. Languages may even develop spontaneously in environments where people live or grow up together without a common language; for example, creole languages and spontaneously developed sign languages such as Nicaraguan Sign Language.

This view, which can be traced back to the philosophers Kant and Descartes, understands language to be largely innate, for example, in Chomsky’s theory of universal grammar, or American philosopher Jerry Fodor’s extreme innatist theory. These kinds of definitions are often applied in studies of language within a cognitive science framework and in neurolinguistics.

Yet another definition sees language as a system of communication that enables humans to exchange verbal or symbolic utterances. This definition stresses the social functions of language and the fact that humans use it to express themselves and to manipulate objects in their environment. Functional theories of grammar explain grammatical structures by their communicative functions, and understand the grammatical structures of language to be the result of an adaptive process by which grammar was “tailored” to serve the communicative needs of its users.

This view of language is associated with the study of language in pragmatic, cognitive, and interactive frameworks, as well as in sociolinguistics and linguistic anthropology. Functionalist theories tend to study grammar as dynamic phenomena, as structures that are always in the process of changing as they are employed by their speakers.

This view places importance on the study of linguistic typology, or the classification of languages according to structural features, as processes of grammaticalization tend to follow trajectories that are partly dependent on typology. In the philosophy of language, the view of pragmatics as being central to language and meaning is often associated with Wittgenstein’s later works and with ordinary language. 

Some theories are based on the idea that language is so complex that one cannot imagine it simply appearing from nothing in its final form, but that it must have evolved from earlier pre-linguistic systems among our pre-human ancestors. These theories can be called continuity-based theories. The opposite viewpoint is that language is such a unique human trait that it cannot be compared to anything found among non-humans and that it must therefore have appeared suddenly in the transition from pre-hominids to early man.

These theories can be defined as discontinuity-based. Similarly, theories based on the generative view of language pioneered by Noam Chomsky see language mostly as an innate faculty that is largely genetically encoded, whereas functionalist theories see it as a system that is largely cultural, learned through social interaction.
