This quantity examines the suggestion of an analytic facts as a typical deduction, suggesting that the proof's price might be understood as its general shape - an idea with major implications to proof-theoretic semantics.

See their note 51 on 37,16 (p. 94); nothing significant turns on this difference. 45. We note that in Alexander’s argument for EE-conversionn, the question of how AiB holds is irrelevant since, no matter how it holds, AiB contradicts NEC(AeB). 46. See the Greek-English Index. 47. 15, 35b11-19. 48. , pp. 200-1. 49. Most of Alexander’s discussion of this passage (39,17-40,4) is devoted to explaining that, although what is contingent may not hold for the most part, Aristotle mentions only what holds for the most part – which, according to Alexander, is the same as what holds by nature – because there is no scientific value in arguments about what holds no more often than it fails to hold.
We here give brief explications of the less usual ones. NEC(P) is read ‘It is necessary that P’. CON(P) is read ‘It is contingent that P’. In the introduction we have tried to ‘unfold’ our understanding of the relevant notion of contingency. Because Aristotle wavers in his understanding we sometimes write ‘CON’(P) to indicate that the notion of contingency is uncertain in one way or another. We frequently write NEC (P) to stand for ‘It is contingent (in another sense) that P’; this sense is so-called Theophrastean contingency; we sometimes use CONt(P) as an abbreviation for NEC (P).
