Episode notes

Life evolved through blind variation and selective retention. This doesn't need a system that copies itself, you just have a single system moving through a serie of configurations. The configurations that are more stable will be the ones that the system retains. And ah, it's that evolutionary process that gives rise to this purposeful, teleological movement that we don't see with inanimate objects.

In this conversation based on his new book, The Romance of Reality, cognitive neuroscientist Bobby Azarian explains how for centuries the question Why do we exist? was the sole province of religion and philosophy. According to the prevailing scientific paradigm, the universe tends toward randomness; it functions according to laws without purpose, and the emergence of life is an accident devoid of meaning. But Azarian argues that out of complexity science and the phenomenon known as emergence, a new cosmic narrative is taking shape: Nature’s simplest “parts” come together to form ever-greater “wholes” in a process that has no end in sight, and that life is moving toward increasing complexity and awareness. Carl Sagan was right when he said of humanity that “we are a way for the cosmos to know itself.”

Shermer and Azarian discuss: laws of thermodynamics and directionality • how complexity formed after the Big Bang • laws of nature: discovered or created or both? • Stephen Jay Gould and contingency vs. necessitating laws of nature • convergent evolution and directionality in evolution • the left wall of simplicity • leading theories for the origin of life • complexity theory and emergence • consciousness, the self, and other minds • free will, determinism, compatibilism, panpsychism • Is there purpose in the cosmos?
