The book is a defended thesis in psycholinguistics. It postulates for the human need of feedback processes to approximate a drive.
Feedback phenomena are explored beginning with the single cell and ending with the human brain, looking to language learning, use, and deficit.
It may serve a good background for another book by the same author, \"Travelers in Grammar\":
\"The (spatial) coordinates constitute the antecedent conditions for language use. They have representation in early neural links, which may account for the cross-linguistic evidence for spatial reference in time expressions in languages of unrelated origins. This reference is known as spatialization. In the light, language grammar could be averred to incorporate aspects of human orientative strategy.\"
