No deduction has two negative premises No deduction has two particular premises A deduction with an affirmative conclusion must have two affirmative premises A deduction with a negative conclusion must have one negative premise.
A deduction with a universal conclusion must have two universal premises He also proves the following metatheorem: All deductions can be reduced to the two universal deductions in the first figure.
His proof of this is elegant. First, he shows that the two particular deductions of the first figure can be reduced, by proof through impossibility, to the universal deductions in the second figure: This proof is strikingly similar both in structure and in subject to modern proofs of the redundancy of axioms in a system.
Many more metatheoretical results, some of them quite sophisticated, are proved in Prior Analytics I.
In contrast to the syllogistic itself or, as commentators like to call it, the assertoric syllogisticthis modal syllogistic appears to be much less satisfactory and is certainly far more difficult to interpret.
Aristotle gives these same equivalences in On Interpretation. However, in Prior Analytics, he makes a distinction between two notions of possibility. He then acknowledges an alternative definition of possibility according to the modern equivalence, but this plays only a secondary role in his system.
Most often, then, the questions he explores have the form: A premise can have one of three modalities: Aristotle works through the combinations of these in order: Two necessary premises One necessary and one assertoric premise Two possible premises One assertoric and one possible premise One necessary and one possible premise Though he generally considers only premise combinations which syllogize in their assertoric forms, he does sometimes extend this; similarly, he sometimes considers conclusions in addition to those which would follow from purely assertoric premises.
Since this is his procedure, it is convenient to describe modal syllogisms in terms of the corresponding non-modal syllogism plus a triplet of letters indicating the modalities of premises and conclusion: The conversion rules for necessary premises are exactly analogous to those for assertoric premises: Aristotle generalizes this to the case of categorical sentences as follows: This leads to a further complication.
Such propositions do occur in his system, but only in exactly this way, i. Such propositions appear only as premises, never as conclusions. He does not treat this as a trivial consequence but instead offers proofs; in all but two cases, these are parallel to those offered for the assertoric case.Transcript of Organ Donation: Persuasive Speech.
