    Reasons Against

    Reason against 1 of 2
    ?
    • 1.Certainty is a psychological state of the knower, not a transferable property of propositions or inferential relations.
      ?

      Think about whether this reason is strong or weak

    • 2.A valid demonstration can yield its conclusion from certain premises while a skeptical inquirer remains unpersuaded, showing certainty is not transmitted by logical form alone.
      ?

      Think about whether this reason is strong or weak

    • 3.Descartes' demon scenario demonstrates that even deductively valid chains from seemingly certain premises can fail to produce certainty if foundational beliefs are themselves vulnerable to doubt.

    Reason against 2 of 2
    ?
    • 1.Aristotle's own Posterior Analytics distinguishes demonstrative knowledge by the necessity of the explanatory connection, not merely by the psychological certainty of premises.
      ?

      Think about whether this reason is strong or weak

    • 2.On the Aristotelian account, a demonstration must proceed from causes, so certainty of premises is insufficient if the inferential link fails to capture the genuine explanatory ground of the conclusion.
      ?

      Think about whether this reason is strong or weak

    • 3.Ibn Rushd's commentary tradition explicitly criticized conflating epistemic certainty with the ontological necessity required for true apodeictic demonstration.

    The distinctive mark of demonstrative arguments—certainty—is characterized in terms of assertion. An assertion p is certain if and only if one holds (i) the justified belief that p and (ii) the justified belief that p cannot be otherwise; a demonstrative argument is one in which certainty is transferred from premises to conclusion. Demonstrative assertions are explicitly identified by Avicenna in the framework of a broader classification of various types of assertions of decreasing epistemic st
