  1. A set theory analysis of belief, knowledge and reality BELIEF

  2. Belief • Acceptance of a proposition as true • Not subject to will • Justification may be flawed • Degrees of certainty • “Believe in” vs. “Believe that” • “Believe in” is shorthand, imprecise speech (implicature) for a more complex “Believe that”

  3. Knowledge • Belief to a high degree of certainty • Absolute certainty is a generally useless concept • Subjective and vague delineation between believe and know • Justified True Belief (JTB) is flawed • Knowledge must be a subset of belief

  4. Real • Proposition is actually true • Verification • Manifestation • Reality thought experiments • Matrix, Brain-in-a-vat, New Evil Demon • Forced to deal with this reality until proven otherwise • Shared perception

  5. Logical “A” and “⌐A” ⌐A A

  6. “X exists” X does not exist X exists

  7. “X committed crime” X did not commit X committed

  8. What does “⌐A” include? ⌐A Z R A E

  9. What does “⌐A” include? ⌐Alphabet Alphabet R A Z E

  10. Believe vs. Real • Belief has no bearing on “real” status • Real value has 2 possibilities • Belief can reject both (noncommittal) • Default position expressed in terms of “A” and not “⌐A” • “Believe” is the proposition • Believe guilty proposition has two positions • Believe not guilty proposition also has two

  11. Believe Guilty? Believe Not Guilty Believe Guilty Believe Innocent

  12. Knowledge as a subset of Belief • Degree of certainty • Subjective, yet consensus is required for shared understanding • Still qualifies as “Belief”

  13. Knowledge as a subset of Belief Believe Know

  14. Agnosticism and knowledge • Rejection of “gnosticism” • Rejection of spiritual/mystical knowledge • General rejection of knowledge • Seems dependent on absolute certainty • Unknowable • Unfounded assertion • Currently unknown • Still dependent on absolute certainty or a degree of certainty that isn’t consistent with usage of “knowledge”

  15. Graphic Agnosticism Agnostic (knowledge) Gnostic

  16. Agnosticism as non-belief • Rejects both belief position • Appears as “middle ground” • Label is misused, but accepted in the colloquial sense • What question is answered by the middle ground?

  17. Agnosticism as non-belief Agnostic (Belief)

  18. Not guilty and Not innocent? Guilty Innocent

  19. Why does belief matter? • Beliefs inform actions • Beliefs inform other beliefs • Worldview understanding is shaped based on what we already accept and understand

  20. What do I believe? • Common reality • A matter of practicality • Science, evidence and reason as a path to understanding • Decision-making skills based on reality • Exploration of possibilities leads to understanding of plausibility • Nothing is sacred • Some ideas are ridiculous • Beliefs matter
