Why it's hard to say incest is wrong | Alex O'Connor

Episode Overview

• This episode explores the philosophical concept of emotivism through the lens of the universal taboo against incest.
• It examines why rational, evolutionary, and religious arguments fail to fully justify why incest is morally "wrong."
• The speaker unpacks how our deepest moral judgments are often expressions of emotion and disgust rather than logical reasoning.
• This content is highly relevant to anyone interested in moral philosophy, ethics, and the psychology behind human taboos.

Key Concepts

• Emotivism as Emotional Expression: Emotivism suggests that moral claims (e.g., "incest is wrong") are not objective facts but rather expressions of emotional attitudes and feelings, such as disgust.
• The Limits of Evolutionary Explanations: While evolution explains why incest is biologically discouraged (to prevent inbreeding), evolutionary science explains why a behavior exists, not whether it is morally justified.
• The Failure of Rationalizing Taboos: When rationalists attempt to strip away complicating factors like power imbalances, they struggle to find a logical reason why consensual incest is wrong, yet they still experience a gut reaction of discomfort, highlighting the primacy of emotion over reason in morality.

Quotes

• At 0:09 - "It's quite easy to explain evolutionarily why this is the case... but evolutionary explanations aren't a justification." - explaining why biological science cannot serve as a foundation for moral rightness or wrongness.
• At 0:39 - "We just think it's disgusting... that's all you've got, ultimately, when you break it down." - highlighting the core premise of emotivism, which is that moral taboos are fundamentally based on raw emotional reactions.
• At 1:04 - "If you try to isolate what the actual difference is there, I think it has to just be an attitude, it's an expression, it's the way you feel." - concluding that moral judgments are ultimately expressions of internal feelings rather than objective truths.

Takeaways

• Recognize that many of your deeply held moral convictions may be rooted in emotional reactions (like disgust) rather than purely logical arguments.
• Avoid conflating scientific or evolutionary explanations of human behavior with moral justifications for those behaviors.
• Use the framework of emotivism to better understand clashes in ethical debates, recognizing that opponents are often expressing conflicting attitudes rather than disputing objective facts.
