New horizons in the study of language

The study of language is one of the oldest branches of systematic inquiry, tracing back to classical India and Greece, with a rich and fruitful history of achievement. From a different point of view, it is quite young. The major research enterprises of today took shape only about 40 years ago, when some of the leading ideas of the tradition were revived and reconstructed, opening the way to what has proven to be very productive inquiry. That language should have exercised such fascination over the years is not surprising. The human faculty of language seems to be a true “species property,” varying little among humans and without significant analogue elsewhere. Probably the closest analogues are found in insects, at an evolutionary distance of a billion years. There is no serious reason today to challenge the Cartesian view that the ability to use linguistic signs to express freely-formed thoughts marks “the true distinction between man and animal” or machine, whether by “machine” we mean the automata that captured the imagination of the seventeenth and eighteenth century, or those that are providing a stimulus to thought and imagination today. Furthermore, the faculty of language enters crucially into every aspect of human life, thought, and interaction. It is largely responsible for the fact that alone in the biological world, humans have a history, cultural evolution and diversity of any complexity and richness, even biological success in the technical sense that their numbers are huge.
