    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Bolzano explicitly distinguishes 'objectual' ideas (Gegenständliche Vorstellungen) from empty ideas (gegenstandslose Vorstellungen) like 'golden mountain'.
      ?

      Think about whether this reason is strong or weak

    • 2.Propositions containing empty ideas are still genuine propositions for Bolzano—they are simply false, not meaningless or existentially importing.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, 'The golden mountain is high' is a well-formed false proposition, not one that presupposes the existence of its subject.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Bolzano's Wissenschaftslehre §28 treats propositions-in-themselves (Sätze an sich) as abstract objects subsisting independently of any minds or existing referents.
      ?

      Think about whether this reason is strong or weak

    • 2.If propositions have ontological status prior to and independent of their subject ideas referring to existing objects, existential import cannot be a condition on proposition-hood itself.
      ?

      Think about whether this reason is strong or weak
