"What raises us above other known sentient beings is our ability to be conscious of our own consciousness. But what does this mean, scientifically?

Consciousness, according to western science, has its roots in the mind, which in turn is seated in the brain. The human brain, with its highly developed frontal cortex, is divided into three distinct parts and includes the cerebrum, cerebellum and the medulla oblongata or stem. The latter is a remnant of our reptilian ancestry with the ocean as its original habitat."
