Episode Details

We naturally want our moral systems to rest on a solid and secure foundation. Yet, the moment we try to ground our values in the natural world, we run into logical barriers that threaten to collapse the entire structure.

In this episode, we explore the core challenges of building an ethical system, focusing on the fact-value gap and the problem of free will. We examine how David Hume challenged the transition from descriptive statements to prescriptive duties, and why G.E. Moore believed that "good" is an indefinable property. We also look at the historical and scientific concepts of determinism and how they conflict with the ethical necessity of personal control.

• Ethical foundationalists look for undeniable first principles similar to the laws of logic.
• Standard logic dictates that a moral conclusion must have at least one initial moral premise to be valid.
• The naturalistic fallacy shows that defining moral goodness using natural properties like pleasure is logically flawed.
• Moral accountability relies entirely on the principle that obligation requires the physical and mental capacity to perform the act.
• Different worldviews, from astrology to Laplace's physics, have challenged human freedom through deterministic frameworks.

The source uses a series of thought experiments—including a scenario involving Deadman, a ghost who possesses bodies, and the Vision, a programmed android—to illustrate how our sense of moral responsibility shifts when an agent lacks conscious control.

How can we justify holding anyone accountable for their actions if every choice is the inevitable result of a preceding cause?
