    Supports→Moore's proof is dialectically flawed and unsuccessful for convincing idealists or external world skeptics that a material world exists

    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.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Skeptics argue perception is globally unreliable because illusions, hallucinations, and dreams show perceptual systems can systematically mislead us.
      ?

      Think about whether this reason is strong or weak

    • 2.Moore's proof assumes 'I have a hand' is known through perception, but if perception itself is doubted, this premise inherits that foundational doubt.
      ?

      Think about whether this reason is strong or weak

    • 3.Moore gains argumentative force only if the premise is more certain than external-world skepticism—but global perceptual doubt undercuts this asymmetry.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Moore's hand is directly available to present experience in ways dreams and illusions typically are not—immediate, persistent, and behaviorally integrated.
      ?

      Think about whether this reason is strong or weak

    • 2.Global skeptical doubt doesn't eliminate justification for particular perceptions; it only shows no perception is infallible—a much weaker thesis.
      ?

      Think about whether this reason is strong or weak

    • 3.Moore's strategy works not by proving certainty but by showing external-world skepticism is less rational than trusting ordinary perceptual judgment about hands.
