    When a false positum conflicts with the present moment, the possibility it describes must be referred to some other time, not the present.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The present moment is necessary: whatever is actually the case now cannot simultaneously be otherwise.
      ?

      Think about whether this reason is strong or weak

    • 2.If you are standing now, you cannot also be running now.
      ?

      Think about whether this reason is strong or weak

    • 3.A false positum (e.g., 'you are running') that contradicts the present state of affairs is impossible at the present instant.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.The obligationes framework treats the positum as establishing a stipulated possible world, not a temporal alternative within the actual world.
      ?

      Think about whether this reason is strong or weak

    • 2.Within a stipulated possible world, 'you are running' can be true at the present moment index without referring to a different time.
      ?

      Think about whether this reason is strong or weak

    • 3.Temporal displacement conflates modal accessibility with temporal accessibility, a distinction Leibniz's possible worlds semantics makes precise.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Medieval logicians like Burley held that a false positum is granted as-if true for the duration of the disputation, suspending not time but the constraint of actuality.
      ?

      Think about whether this reason is strong or weak

    • 2.If the positum suspends actuality rather than relocating the proposition temporally, its possibility is grounded in logical compossibility, not temporal indexing.
      ?

      Think about whether this reason is strong or weak

    • 3.P4 of the supporting argument illicitly assumes that possibility requires a real accessible time, ruling out purely logical or intentional possibility by fiat.
      ?

      Think about whether this reason is strong or weak

    Time and modality. When discussing modalities in his Ordinatio (I, d. 38, 2), John Duns Scotus rejects a principle which he calls an obligational rule, namely that with a false positio one must “deny the present instant”. And in fact, Walter Burley (writing roughly at the same time) mentions this as a valid, useful rule. The reasoning behind the rule is the necessity of the present. For example, suppose “you are running” is the false positum when you are in fact standing in a university hall and
