70 - Substance Dualism w/ Michael Huemer
Philosophy Professor Michael Huemer defends interactionist substance dualism, discussing challenges of explaining consciousness physically, human behavior without mental states, personal identity, and implications of different theories on what happens after death. They explore the debate on cognitive abilities in the brain vs. soul, and delve into the concept of reincarnation, discussing the relationship between the soul and the body.

69 - Alien Apologetics w/ Jimmy Akin
Wouldn’t aliens manage to avoid crashing their ships, given how advanced they’d have to be? Aren’t the distances between life-supporting planets too vast to feasibly travel? If figures in the government actually knew something, wouldn’t a cover-up involve too many people to keep the secret for long?
I’m joined by Jimmy Akin to answer ten common objections to UFO phenomena and alien visitations. In the wake of recent news stories about unidentified aerial phenomena, I heard the same skeptical talking points trotted out over and over again as if UFO believers had never considered them and had no response to them at all. So I’d like to play whatever small part I can in improving the quality of the discourse by advancing the conversation past the initial thoughts that are commonly offered into more interesting territory. This should make skeptics better skeptics, and help agnostics like myself better appreciate the skeptical position. Right now, the skeptics are not sending their best.

68 - Encountering Mystery w/ Dale Allison
Today I’m speaking with Dr. Dale Allison, historian and author of Encountering Mystery: Religious Experience in a Secular Age. The subtitle of the book notwithstanding, the unusual experiences we discuss are not explicitly religious. They’re usually interpreted through a religious lens (often without any reflection), but almost all of them needn’t be, which is something we return to quite a bit. Flatly disputing the phenomenon is not the only option available to the nonreligious.
We talk about paranormal and parapsychological phenomena, and two major sources of skepticism towards things that fall into those categories. On the one hand, of course, there’s materialism, conservative naturalism, skepticism (as in, the skeptic community), etc. But Protestant Christianity, I was surprised to learn, has also been a skeptical force in history due to their drive to debunk Catholic miracle stories, or even just extraordinary events documented by the Catholic Church that explicitly or implicitly were used as evidence for Catholicism.
Since we’re exploring new terrain that involves some quite unusual topics (e.g., clairvoyance, levitation, visions of dead loved ones, etc.) there’s a lot more I want to say, even in this little description box, but I’ll save it for the interview.
One thing I forgot to mention during the interview: In addition to Dr. Allison’s book, there are a couple podcasts that regularly discuss cases like the ones that came up today in greater depth. “Otherworld” and “Jimmy Akin’s Mysterious World” come highly recommended from me.

66 - Wittgensteinian View of Concepts (The Failure of Analysis)
Today, we discuss the idea that understanding a concept is not a matter of knowing a definition. As philosopher Michael Huemer argues, our main access to a concept comes “not through directly reflecting on the concept, but through activating the dispositions that constitute our understanding.”
The Wittgensteinian view of concepts explains how it’s possible that we know how to competently use terms even though it is so hard to successfully analyze them. I can’t provide a perfect conceptual analysis of knowledge (no one can), and yet I have no issue using the term and understanding what it means. Not only can I competently use words that I can’t analyze, I can reject proposed analyses as insufficient, like the justified true belief analysis. That’s because I understand the meaning of the concept, despite the fact that I can’t define it.
“Indefinability of words is perfectly normal," Huemer argues, "since understanding is not constituted by knowledge of definitions. The best way to convey a word’s meaning is through examples.”

One note from Huemer on the Wittgensteinian view of concepts and the contrasting Lockean view: "I think what I have to say about concepts is like some stuff that Wittgenstein said, but I don’t actually care how well it matches Wittgenstein’s views. I also don’t care, by the way, whether the 'Lockean theory' matches Locke’s views. You have to add in caveats like this whenever you mention a major philosophical figure, because there are always people who have devoted their lives to studying that figure and who, if you let them, will give you all sorts of arguments that the famous philosopher has been completely misunderstood and never really said the things they’re famous for saying."

65 - The Defeasibility Theory: What is Knowledge?
What is knowledge? What does it mean to know something? Today, we discuss the defeasibility theory, which adds a fourth condition to the famous "justified true belief" analysis of knowledge. We also touch on Gettier cases, certainty, and what contemporary analytic philosophy is all about (the answer may surprise you!).

The Hypothesis of Indifference - Breaking the Binary
We take a short break from our epistemology series to talk about the hypothesis of indifference, a limited God, natural teleology, pan-agentialism, and how value-orientation in the universe is not binary but rather comes on a continuum.
For reference, Paul Draper (1989) characterizes the hypothesis of indifference as follows: “neither the nature nor the condition of sentient beings on earth is the result of benevolent or malevolent actions performed by non-human persons.”
If the audio sounds different than usual, that's because I recorded this as a video and edited it slightly differently as a result. You can watch the video on YouTube here

64 - Internalism: The Nature of Justification
This is part one of a series about epistemology, the branch of philosophy concerned with knowledge and justification. When does something count as knowledge? How can we be justified in accepting mathematical truths, moral truths, and truths about the external world? Can I trust my perceptual faculties, my memory, my ability to reason? Can I know anything at all?
Today, we're discussing internalism vs. externalism about knowledge and justification. We also touch on the person-based nature of justification, giving others the benefit of the doubt, and empathy on the epistemic landscape.
