Overview of Julian Jaynes's Theory

In January of 1977 Princeton University psychologist Julian Jaynes (19201997) put forth a bold new theory of the origin of consciousness and a previous mentality known as the bicameral mind in the controversial but critically acclaimed book The Origin of Consciousness in the Breakdown of the Bicameral Mind. Jaynes was far ahead of his time, and his theory remains as relevant today as when it was first published.

Jaynes asserts that consciousness did not arise far back in human evolution but is a learned process based on metaphorical language. Prior to the development of consciousness, Jaynes argues humans operated under a previous mentality he called the bicameral ('two-chambered') mind. In the place of an internal dialogue, bicameral people experienced auditory hallucinations directing their actions, similar to the command hallucinations experienced by many people who hear voices today. These hallucinations were interpreted as the voices of chiefs, rulers, or the gods.

To support his theory, Jaynes draws evidence from a wide range of fields, including neuroscience, psychology, archeology, ancient history, and the analysis of ancient texts. Jaynes's theory has profound implications for human history as well as a variety of aspects of modern society such as mental health, religious belief, susceptiblity to persuasion, psychological anomalies such as hypnosis and possession, and our ongoing conscious evolution.

Jaynes's theory can be broken down into four independent hypotheses:

  1. Consciousness as he carefully defines it is a learned process based on metaphorical language.
  2. That preceding the development of consciousness there was a different mentality based on verbal hallucinations called the bicameral ('two-chambered') mind.
  3. Dating the development of consciousness to around the end of the second millennium B.C. in Greece and Mesopotamia. The transition occurred at different times in other parts of the world.
  4. The neurological model for the bicameral mind.

Why Julian Jaynes's Theory is Important

There are a number of reasons why Julian Jaynes's theory is very important to understand. These include:

  1. It provides a more accurate view of human history.
  2. Jaynes's definition and understanding of consciousness brings more clarity to the issue than other theorists.
  3. It explains a wide range of otherwise inexplicable phenomena (divination, idols, monumental mortuary architecture, hallucinations, imaginary companions, etc.)
  4. It explains the origin of religion.
  5. It provides a historical context for hearing voices, which is often comforting to those who have the experience.
  6. It provides a neurological model for hearing voices, which has now been verified in dozens of brain imaging studies, that could help lead to future treatments for those with persistent, obtrusive voices.

Understanding Jaynes's Theory

There is no short cut to understanding Jaynes's theory. Brief summaries and reviews do not do it justice, and unfortunately many of the comments written on the theory online (including Wikipedia) often contain mistakes. Rather than reading other people's misunderstandings and misconceptions, we recommend that you study Jaynes's theory yourself and form your own opinion. If you are interested in gaining a thorough understanding of Jaynes's theory, we recommend the following:

Step 1 Start by reading Jaynes's book, The Origin of Consciousness in the Breakdown of the Bicameral Mind.
Step 2 Next, read The Julian Jaynes Collection, which contains additional material by Jaynes as well as interviews and in-depth discussion of his theory, and Reflections on the Dawn of Consciousness: Julian Jaynes's Bicameral Mind Theory Revisited, which provides additional discussion of Jaynes's ideas by a variety of scholars, as well as articles by Jaynes himself. Reflections expands on various aspects of Jaynes's theory, updates the reader on research relevant to his ideas, and addresses criticisms of Jaynes's theory.
Step 3 Listen to the Audio CDs on Jaynes's theory and read The Jaynesian, the newsletter of the Julian Jaynes Society. Both of these provide additional insights and discussion on Jaynes's theory.
