    It is not the case that Moore's proof is dialectically flawed and unsuccessful for convincing idealists or external world skeptics that a material world exists

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The purpose of Moore's proof is to convince idealists and external world skeptics that a material world exists
      ?

      Think about whether this reason is strong or weak

    • 2.Idealists and global skeptics do not believe that a material world exists
      ?

      Think about whether this reason is strong or weak

    • 3.Because idealists and skeptics do not believe that a material world exists, they are rationally required to distrust any perceptual evidence offered in favor of the premise that Moore holds up a hand
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Wittgenstein's 'On Certainty' shows that Moore's proof begs the question by treating as a premise what skeptics place in doubt.
      ?

      Think about whether this reason is strong or weak

    • 2.A valid argument that assumes its conclusion's presuppositions cannot transmit justification to someone who denies those presuppositions.
      ?

      Think about whether this reason is strong or weak

    • 3.Since skeptics deny the reliability of perception globally, Moore's perceptual premise 'I have a hand' inherits exactly the doubt the proof was meant to resolve.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Crispin Wright's transmission-failure thesis establishes that warrant does not always transmit across valid inference when the conclusion is a precondition for trusting the premise.
      ?

      Think about whether this reason is strong or weak

    • 2.Moore's inference from 'here is a hand' to 'an external world exists' fails transmission because the existence of the external world is a precondition for the perceptual warrant behind the premise itself.
      ?

      Think about whether this reason is strong or weak

    • 3.An argument that presupposes what it concludes in its evidential base is dialectically circular and cannot rationally move a disputant who rejects that base.
      ?

      Think about whether this reason is strong or weak
