17023. "THE ORIGINS OF CONSCIOUSNESS IN THE BREAKDOWN OF THE BICAMERAL MIND" BY JULIAN JAYNES (BOOK REVIEW). This paper discusses Jaynes’s unique theory on the emergence of self-consciousness in humans, including the existence of hallucinatory voices in ancient man and the ‘vestiges’ of the bicameral mind in the contemporary world. Although the theory is both speculative and controversial, it is worthy of further study and debate. Keywords: human consciousness ancient. 5 pages; 9 footnotes; 1 bibliographic source.
