Consciousness and Language
Of the 10–14 million species currently living on Earth and the estimated 5 billion species now extinct, only human beings possess rationality and sophisticated language, signifying an ontological discontinuity between humans and other animals. These two human characteristics appear to have emerged simultaneously and rapidly.
Origins of Human Consciousness
“A promising approach to finding the beginnings of human rationality may lie with the study of language. This is paradoxical, perhaps, in that spoken language leaves no fossils or artifacts. One can, however, investigate the neural machinery of language, the genetic basis of that machinery, and the deep underlying structures of language itself."
