Aristotelian Syntax from a ComputationalCombinatorial Point of View

This paper translates Aristotelian logic into the sphere of computationalcombinatorical research methods. The task is accomplished by formalizing Aristotle's logical system in terms of rule-based reduction relations on a suitable basic set, which allows us to apply standard concepts of the theory of such structures (Newman lemma) to the ancient logical system. In this way we are able to reproduce Aristotle's method of deriving syllogisms within a precisely defined formal environment, and we can analyse the structure of the set of syllogistic rules by means of a computer program. Thus we show that Aristotle's syllogistic logic is a formal system of its own, which can be modelled independently of predicate logic and set theory. Our research is very much in the spirit of Smiley's and Corcoran's modelling of Aristotelian logic as a deductional system, and we aim to stay close to Aristotle's own term logical concepts.
Keywords: Aristotelian logic, syllogistic
