    Reasons For

    1 perspective
    Reason for
    ?
    • 1.There are no contradictory contingent facts or truths.
      ?

      Think about whether this reason is strong or weak

    • 2.If there are no contradictory contingent facts, then the Principle of Noncontradiction governs contingent truths just as it governs necessary truths.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Dialetheists like Graham Priest argue that some true contradictions exist, making PNC a revisable logical norm rather than an absolute constraint.
      ?

      Think about whether this reason is strong or weak

    • 2.If PNC is revisable even for necessary truths, its application to contingent truths cannot be stronger or more universal than its already-contested necessary domain.
      ?

      Think about whether this reason is strong or weak

    • 3.A principle that admits exceptions at the necessary level cannot coherently claim unrestricted governance over the contingent level.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Leibniz himself distinguished PNC as governing necessary truths and PSR as the distinct principle required to govern contingent truths.
      ?

      Think about whether this reason is strong or weak

    • 2.If contingent truths required only PNC for their governance, Leibniz's Principle of Sufficient Reason would be explanatorily redundant for the contingent domain.
      ?

      Think about whether this reason is strong or weak

    • 3.The historical architecture of rationalist modal epistemology presupposes that PNC alone is insufficient to determine which contingent truths obtain.
      ?

      Think about whether this reason is strong or weak

    We must therefore distinguish distinct ways of associating the principles with various domains. The first way is to specify the domain to which each principle applies. Leibniz appears to believe that, according to this approach, there is a single universal domain and it is associated equally with each principle. There are no contradictory contingent facts or truths and so the Principle of Noncontradiction applies to all contingent truths as well as all necessary truths. Likewise, it is usually a
