• “The term “belief” can be used casually or rigorously.” This introductory sentence sets the stage for the nuanced exploration of belief, distinguishing between its casual and rigorous uses.
  • “Casual, Binary Belief: In everyday conversation, belief often operates as a binary concept—either one believes something to be true, or one does not.” This statement succinctly captures the essence of casual, binary belief, underlining its black-and-white nature.
  • “Rigorous, Gradient Belief: In contrast, situations that involve significant consequences…demand a more nuanced approach to belief.” This contrasts the simplistic nature of binary belief with the complexity of gradient belief, which accommodates varying degrees of certainty.
  • “Adopting more nuanced and gradient expressions of epistemic certainty…enhances decision-making, communication, and critical thinking, while fostering intellectual humility and openness.” This quote, highlighting the benefits of nuanced expressions of belief, underscores their significance in promoting rationality and adaptability in the face of complexity and uncertainty.
  1. The term “belief” can be used casually or rigorously. When “belief” is used casually, it is normally used as a binary concept, such as shown in the statements, “I believe it will rain tomorrow” or “I don’t believe we’ve met.” In everyday discourse, this casual, binary use of belief is useful in that it allows us to avoid a deep epistemic analysis of the actual degree of belief we hold. We can change our minds later at little risk or add hedging devices such as “I tend to believe…” or “It seems to me that…”. However, if a medical doctor were to tell us we had cancer and then give us a binary prognosis of either “I believe you will recover” or “I believe you will die”, we would likely not be very happy. We would suspect that the doctor had available evidence that warranted a more nuanced statement of epistemic confidence. Please provide your brief and focused comments on these two notions of belief, one being casual and binary, and the other being more rigorous and intrinsically gradient.

  3. The notion of belief that is non-binary and captures varying degrees of certainty can be considered a foundational or primary concept in epistemology. This “first-order” category, characterized by its nuanced semantic nature, includes terms such as “credences,” “confidence levels,” and “epistemic probabilities,” which all reflect the gradient nature of belief and understanding. These terms allow for a detailed expression of how strongly one holds a belief, acknowledging the spectrum of certainty that ranges from doubt to conviction without committing to a binary position. In contrast, terms like “convinced,” “assent to,” “know,” and “persuaded” belong to a category that might be termed secondary epistemic terms. These “second-order” terms are more binary in nature, implying a more definite stance or decision about belief. They suggest a point at which one has crossed from uncertainty to a degree of certainty or acceptance that is more absolute, resting on subjective thresholds that define the transition from one binary state to another. Provide more exhaustive lists of terms in each of these categories.

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.
