Imagine a united consciousness, an awareness of which all of our minds are a part – and a potential way out of the division, greed, and destruction that threaten to engulf our world.
What is consciousness and how can a brain, a mere collection of neurons, create it?

The human brain has evolved a complex circuitry that allows it to be socially intelligent. This social machinery has only just begun to be studied in detail. One function of this circuitry is to attribute awareness to others: to compute that person Y is aware of thing X.
