Well put.

However, please note that there have been a few individuals in human history who did have complete understanding of consciousness. The story of this world is that nobody wanted to learn from those people when they were alive.

The reasons that modern scientists do not understand consciousness is that

1. they do not apply a specific principle to their research (In math, when we want to solve a question, we apply the equality to operate the question.) and because

2. their research only investigates half of the set of existent relevant phenomena - that which can be seen with the naked eye.

Once a human recognizes the simple law that governs natural phenomena it is simple to recognize what consciousness is.

I am fairly certain that a large percentage of the human population still operates regularly without the consciousness as described by Jaynes.

At the very least, the genetically built neural machinery that our species would've had 3000 years ago is still likely to reward behaviors such as assuming gods and spirits in almost everything, enthralling oneself in crowd dynamics, and yielding to charismatic authorities.
