Why Do People Still Believe in God?! | ft. Richard Dawkins and Alex O'Connor | Thinkable Presents

Alex O'Connor introduces Richard Dawkins, highlighting his significant impact on public atheism and his latest book, 'The Genetic Book of the Dead.' Dawkins explains the central metaphor of his book: an animal as an 'evolutionary palimpsest,' where ancestral environments are inscribed into its biology, with older records overwritten by newer ones, akin to how ancient manuscripts were reused.

Dawkins discusses examples of 'evolutionary blunders' that reveal historical relics within animal anatomy, such as the human back pain (a remnant from quadrupedal ancestors) and the absurdly long recurrent laryngeal nerve in giraffes (and other tetrapods). This nerve takes an inefficient detour due to its evolutionary history, stemming from its original, shorter path in fish ancestors. He emphasizes that 'poor design' is rare, as natural selection typically optimizes organisms for their environments.

Dawkins defends his gene-centered view of evolution, positing that the gene is the fundamental unit of selection due to its potential for immortality through informational copies. He addresses recent criticisms, including those from Dennis Noble, who suggests DNA is merely a library for protein synthesis rather than a causal driver of evolution. Dawkins counters that genes exert crucial causal influence on an organism's survival and reproduction, enabling their perpetuation.

Dawkins speculates on the idea of genes as a 'gigantic colony of symbiotic viruses,' distinguishing between vertical (passed down through generations) and horizontal parasites. He argues that vertically transmitted parasites, like mitochondria and our own genes, align their interests with the host's survival. He also provides examples of accelerated natural selection, such as the peppered moth's color change during the Industrial Revolution and the adaptation of mosquitoes in the London Underground.

The discussion delves into convergent evolution, illustrated by Australia's marsupial fauna, which independently evolved forms resembling placental mammals in other parts of the world. Dawkins also touches on species that returned to water and then land, highlighting the palimpsest nature of evolution. He then addresses common misunderstandings in evolutionary biology, particularly the underestimation of evolutionary time and the misconception of evolution as a chance process rather than a gradual, cumulative improvement exemplified by the evolution of the eye.

Dawkins challenges Michael Behe's concept of 'irreducible complexity' (e.g., the mousetrap analogy) by offering the 'argument from personal incredulity.' He explains how complex structures like wings can evolve gradually through incremental advantages, using the example of a squirrel-like animal developing membranes for gliding, leading ultimately to bats. He points to Kenneth Miller's work as a robust counter to Behe's arguments.

Dawkins defines his 'cultural Christianity' as a reflection of his upbringing in a Christian culture, not a belief in actual Christian tenets. He addresses criticism that 'New Atheism' created a 'meaning vacuum,' denying it was a 'project' and expressing skepticism about unintended consequences. He reflects on his recent conversation with Jordan Peterson, noting Peterson's 'drunk on symbols' approach, where symbolic resonance often overrides factual accuracy, a characteristic Dawkins attributes to certain theologians.

Dawkins defines the God he rejects as an 'intelligent creator' or 'divine mathematician' whose existence would revolutionize science. He dismisses alternative theological definitions that equate God with 'being itself' or 'good' as uninteresting and lacking substance. He also discusses the future of science, predicting breakthroughs in understanding the origin of life and the unification of quantum theory and relativity. He believes science and religion (defined as belief in a supernatural creator) are incompatible.

Dawkins dismisses the idea of a 'last stage' in human evolution, noting that evolution is an ongoing process. He speculates that AI might surpass human capabilities, leading to our eventual 'disappearance' as our 'artifacts' (AI) continue to evolve. He also considers the future impact of genetic engineering on human evolution. On morality, he argues it's a field for philosophy and societal design, not religion. He supports Steven Pinker's view that humanity is, on the whole, becoming more moral and less violent, and aligns with the axiom of minimizing suffering for sentient beings.

Dawkins identifies the 'fine-tuning' argument for the universe's physical constants as the most challenging objection he faces. He counters it with the multiverse hypothesis or the idea that current physics is incomplete. He vehemently refutes any suggestion of a deathbed conversion for himself, referencing Christopher Hitchens' similar stance and criticizing books that attempt to posthumously assign faith to atheists. He expresses his dislike for cliché questions about 'free will' and 'advice to young people,' emphasizing the importance of understanding an audience's perspective.
