> Consequently, say the signatories, the scientific evidence is increasingly indicating that humans are not unique in possessing the neurological substrates that generate consciousness. That's because neurological substrates don't generate consciousness. There is no evidence to the effect that they do. However, when we understand the structure of the system of consciousness it's very easy to see how consciousness is generated and maintained. The role of all neural systems is 1. to transmit to the consciousness what the body sees, hears, learns, etc., and 2. to express what is in consciousness through the body.
