Reality and Noetic Quality

What are the best competing theories of consciousness? Can we isolate where it arises and measure how complex it is? How do 5meo DMT mystical or non-separation experiences shift worldviews on consciousness?

In this episode we have the very theme of the podcast’s title to delve into, the quest to understand the nature of consciousness. So we discuss mind and self, and what kind of substrate you need to allow for subjective experience; we look at the various philosophical positions on the nature of consciousness and ways to move beyond the unwinnable argument around the hard problem; we talk about extended cognition and cellular cognition; how integrated information theory attempts to quantify consciousness; the origin of meaning; psychedelics and the implications of mystical experiences of non-separation; whether AI will ever become conscious; and the implications of plant intelligence and memory.

There’s only one person who can speak about such a wide range of topics this well, one of the most passionate consciousness researchers in the world for over 40 years, physicist and neuroscientist, Christof Koch. He’s Chief Scientist at the BlueDot Foundation, and has authored and co-authored over 1000 scientific papers and 6 books, including “The Quest for Consciousness”, “Confessions of a Romantic Reductionst” and “Then I am myself the World”, which we’ll be focussing on today.
