This book "asserts that the origin and spread of languages must be examined primarily through the time-tested techniques of linguistic analysis, rather than those of evolutionary biology" and "defends traditional practices in historical linguistics while remaining open to new techniques, including computational methods" and "will appeal to readers interested in world history and world geography."
The Nature of Rules, Regularities and Units in Language
A Network Model of the Language System and of Language Use
Comprehensive networks of language make use of structures that go beyond the basic associative connections that can be found in the brain. The present study is an attempt to provide an account of language that restricts itself to structures of a neurophysiological kind, i.e. simple nodes, excitatory and inhibitory connections.
