    Reasons Against

    Reason against 1 of 2
    ?
    • 1.For Aristotle, a genuine syllogism requires premises that are true, primary, and better known than the conclusion (Posterior Analytics I.2).
      ?

      Think about whether this reason is strong or weak

    • 2.An argument from false premises cannot constitute scientific knowledge (episteme), which is the telos of Aristotelian demonstration.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, structural validity alone is insufficient for Aristotelian deduction in its primary sense, which is inseparable from truth conditions.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Relevance logicians (Anderson and Belnap) argue that validity requires the premises to be genuinely relevant to the conclusion, not merely formally connected.
      ?

      Think about whether this reason is strong or weak

    • 2.An argument whose validity is purely structural permits paradoxes of material implication, where false premises entail any conclusion whatsoever.
      ?

      Think about whether this reason is strong or weak

    • 3.A deduction whose structure 'guarantees validity' regardless of content violates the intuition that logical consequence tracks real inferential dependence.

    In Aristotle’s logic, the basic ingredients of reasoning are given in terms of inclusion and exclusion relations, of the sort graphically captured many years later by the device of Venn diagrams. He begins with the notion of a patently correct sort of argument, one whose evident and unassailable acceptability induces Aristotle to refer to is as a ‘perfect deduction’ (APr. 24b22–25). Generally, a deduction (sullogismon), according to Aristotle, is a valid or acceptable argument. More exactly, a d
