This book "supplies a vocabulary of English words and idiomatic phrases 'arranged … according to the ideas which they express'. The thesaurus, continually expanded and updated, has always remained in print, but this reissued first edition shows the impressive breadth of Roget's own knowledge and interests."
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.
