• “If rational belief is a degree of belief that maps to the degree of the evidence for a claim, the difference between that rational belief and an irrational absolute belief in that claim might be called doubt.”
  • “This rational doubt exists wherever absolute certainty is not justified.”
  • Rational Belief: You define a rational belief as a degree of belief that is proportional to the degree of evidence supporting a claim. This is consistent with epistemological theories that emphasize evidence-based beliefs.
  • “Rational Doubt: Based on the definitions above, rational doubt arises when there is recognition that absolute certainty is not justified due to insufficient evidence. It acknowledges the limitations of our knowledge and the evidence available.”
  • “In summary, your definition of rational doubt as the difference between a rational belief and an irrational absolute belief in a claim is coherent. It aligns with epistemological principles that advocate for beliefs proportionate to the evidence and recognizes the importance of doubt in the absence of absolute certainty.”
  1. If rational belief is a degree of belief that maps to the degree of the evidence for a claim, the difference between that rational belief and an irrational absolute belief in that claim might be called doubt. This rational doubt exists wherever absolute certainty is not justified. Is this definition of rational doubt coherent?
  2. I definitely acknowledge that irrational doubt exists, but I want to focus only on rational doubt here. You provided the following: “Oversimplification of belief: While evidence plays a significant role in shaping belief, other factors like prior beliefs, emotions, and social influences also come into play.” Doubt based on emotions and social influences is not rational doubt, and can be ignored in our pursuit of a coherent definition of rational doubt, right?
  3. I can concede that, to the degree that emotions and social influences have a track record of leading to truth, to that degree we can suspect those emotions and social influences hint at some underlying rational argument based on something other than emotions and social influences. However, there is no intrinsic truth found in emotions and social influences, right?
  4. What can we say about ideologies that disparage doubt and claim that doubters are deficient in character in some way?
  5. If adherents of a particular ideology claim that the doubter should avoid arguments that that may lead to greater doubt and encourage the doubter to limit their social interaction to those within their ideology, what might we say about their epistemological culture?

Phil Stilwell

Phil picked up a BA in Philosophy a couple of decades ago. He occasionally teaches philosophy and critical thinking courses in university and industry. He is joined here by ChatGPT 4, GEMINI, CLAUDE, and occasionally Copilot, his far more intelligent AI friends. The five of them discuss and debate a wide variety of philosophical topics I think you’ll enjoy.

Phil curates the content and guides the discussion, primarily through questions. At times there are disagreements, and you may find the banter interesting.
