Language

Language is the human ability to acquire and use complex systems of communication, and a language is any specific example of such a system. The scientific study of language is called linguistics.
The philosophy of language, such as whether words can represent experience, has been debated since Gorgias and Plato in Ancient Greece, with later thinkers such as Rousseau arguing that language came from emotions, while others like Kant held it came from logical thought. 20th-century philosophers such as Wittgenstein argued that philosophy is really the study of language. Major figures in linguistics include Ferdinand de Saussure and Noam Chomsky.
