Reality, Illusion, Skepticism, Love & Beauty - D.C Shindler (EP 36)
David C. Shindler is a Professor of Metaphysics and Anthropology at the
John Paul II Institute, Washington, DC.
If modern physics tells us that time and reality are not as they appear
to us, what is real? Can we ever know and touch reality? Relatedly, does
objective truth exist (or is it just in our minds)? This podcast
explores these questions through philosophy.
In this podcast, we consider the nature of truth, whether reality could
be an illusion, how to deal with skeptical over the realness of truth,
as well as how love, beauty, and goodness, relate to these questions.

Meditation And Pure Consciousness Experiences - Toby Woods | EP 23
Toby Woods is a scientist at the Monash Centre for Consciousness and
Contemplative Studies.
Subjective experience is notoriously difficult to study scientifically.
This is even more the case for subjective experience in meditation and
for this reason it has not been widely examined. In this podcast I am
joined by Toby Woods, who is part of a growing movement to examine
meditation experiences in a systematic and fine-grained manner using
scientific methods.
In the podcast we discuss the experience of "stillness" or "pure
consciousness" in meditation, including the content that is present and
absent, and we compare the experiences attained in different types of
practices. We also look at the benefits of accessing the stillness and
the risks and benefits of practising meditation more generally.

UFOs, Aliens, Existential Risks, Prediction Markets, and Academia - Robin Hanson | EP 21
Robin Hanson is an economist at George Mason University.
In this podcast we start off by exploring the panspermia hypothesis as a
plausible explanation for both the origins of life on earth and UFO
sightings. We then delve into existential risks to our species, such as
declining population levels and AI. Finally, we cover the nature of
money, economics, prediction markets, and academia and science.

Collective Intelligence, Swarms, and Multifractal Social Psychology - Damian Kelty-Stephen: EP18
Damian Kelty-Stephen is a psychologist focused on understanding complex
behaviors such as movement, language, and perception.
Traditional cognitive science often views organisms as having a
centralized controller in the brain to govern behavior. But what if we
could better understand organisms as collective intelligences,
exhibiting behaviors we typically associate with swarm organisms, like
bees?
In this episode, we discuss intelligence without a central controller
and intelligence beyond brains. We explore how complex behaviors might
be explained without centralized control systems. We also touch on the
importance of neurons, the intelligence of cells, and compare biological
with technological intelligence.

Complexity, Consciousness, and Integrating Science and Mythology - Brett Andersen (EP 1)
Brett Andersen is a PhD student studying evolutionary psychology. We
discuss how different models of cognition are increasingly being bridged
together and how they relate to our world today. This is giving us the
tools to appreciate the place of science and mythology in our culture,
as well as helping to develop scientific accounts of meaning, mythology
and God.
READING AND EXTRA INFO
Brett is a PHD student who is studying evolutionary psychology. His
academic work focuses on autistic vs schizotypal spectrum. He has a
Substack where is writing on topics such as our left hemisphere
dominance as a culture, scientific account of mythology, and how we come
to have morals and values.
He recently wrote a paper with John Vervaeke bridging the relevance
realisation theory of cognition with predictive processing which can be
found here:
