Find out how consciousness is generated in the human brain - and discover the evidence suggesting some animals are also sentient. Read Nicholas's book 'Sentience: The Invention of Consciousness' here: https://geni.us/eCGs Watch the Q&A here: https://www.youtube.com/watch?v=cBIa1KeXEWk Donate to the RI and help us bring you more lectures: https://www.rigb.org/support-us/donate-ri Join renowned psychologist and philosopher Nicholas Humphrey as he presents his theory of 'phenomenal consciousness', in full for the first time. Weaving together leading-edge science and personal breakthrough experiences, Nicholas provides a comprehensive look at the evolution of consciousness. He discusses discovering blindsight in monkeys, hanging out with mountain gorillas in Rwanda, to becoming a leading philosopher of the mind; all leading to a scientific understanding of consciousness and his theory as to how conscious feeling is generated in the human brain. This theory also provides the foundation for Nicholas' controversial opinion - in contrast to broad scientific opinion - that phenomenal consciousness is only present in warm-blooded creatures such as mammals and birds, and not invertebrates like octopuses and bees, despite their known intelligence.
