78 - Ghosts? Yeah, why not. Ghosts.
Today we discuss three skeptical arguments from Wang Chong, a first-century Chinese philosopher who railed against the belief in ghosts. Although the skeptics who initially presented these arguments to me seemed to think they were decisive, I was unimpressed and wanted to explain why I think they miss the center of the spectral target.
As summarized on Wang’s IEP entry:
(1) Argument from physical shape: The death of a person is the result of the body losing the animating qi (vital essence), and once the qi is separated from the body, the body decays. All will admit to this. If this is so, however, and the person’s qi is still existent, how can this qi itself manifest in the form of a physical shape? It is not a body, it is qi. But when one sees a ghost, one sees a body. But if the person has died, they no longer have a body, so where could they get another one? They cannot take over another living body, which will already possess its own qi. Thus, the view that people when they die become ghosts is nonsensical.
(2) Argument from population: If people become ghosts when they die, there should be more ghost sightings than living people, as the number of people who have lived in the past and died is far greater than the number of people now living. This is not true — ghost “sightings” are rare. Thus it cannot be that people when they die become ghosts.
(3) Argument from ghostly efficacy: If a living person is harmed, this person will immediately go to a magistrate and bring a case against the party who harmed them. If it were the case that people become ghosts when they die and can interact with living humans, every ghostly murder victim would be seen going to a magistrate, telling him the name of the killer and the means of murder, leading him to the body, and so forth. This is never witnessed (ever).

77 - The Knowledge Argument Against Physicalism - A New Angle
Explore the fascinating tale of Mary, the color scientist, and her intriguing encounters with her cousin Fred and a colorblind neuroscientist. Delve into the limits of physical knowledge and its inability to fully capture conscious experiences. Philip Goff challenges the ability hypothesis and presents 'phenomenal curiosity' as a threat to moderate forms of physicalism. This thought-provoking discussion critiques various responses to the knowledge argument while shedding light on the nature of consciousness.

The core theory, weak and strong emergence, micro-reductionism, and Sean Carroll’s skeptical argument against everything. Is Dr. Carroll correct in holding that physics has ruled out the afterlife, the soul, fundamental consciousness, parapsychology, and other immaterialist claims?

71 - Against Epiphenomenalism
Epiphenomenalism is the view that mental states have no effect on anything. The feeling of pain, counterintuitively, does not cause your aversion, mentally or physically. Beliefs don’t cause behavior. None of our actions occur in virtue of our thoughts, feelings, or sensations.
Inspired by Matthew Adelstein’s post defending epiphenomenalism, I want to explain my opposition to the view. A few times, he referenced a podcast episode / blog post of mine from 2020, which I hadn’t read since it was first posted. I found a few things to disagree with in my own episode, so I thought I’d respond to Matthew and try to offer an updated critique of epiphenomenalism in the process. While epiphenomenalism is probably less wrong than physicalism, the causal efficacy of our mental states is as evident as anything, so the view should still be rejected in favor of panpsychism or interactionist dualism. As Paul Draper once put it, “wild ideas are needed” to explain consciousness, but I don’t think epiphenomenalism is the right wild idea.
After responding to a few key points from Matthew, I offer a few reasons to reject epiphenomenalism:
Epiphenomenalism is self-defeating.
The evidence that supports the causal influence of mental states is the exact same kind of evidence for causal influence in other cases. This not only supports mental causation, but also raises the threat of undermining the epiphenomenalist’s claim that the physical has causal powers.
The phenomenal powers view as defended by Mørch (2017, 2020) is plausible and entails the falsity of epiphenomenalism. In short, there are plausible examples of causal necessity in the mind.
Among metaphysical theories of consciousness, epiphenomenalism is the most vulnerable to the problem of psychophysical harmony.
