2Aristotle's Logic at the Department of Philosophy of the University of BuffaloIdeas Y Valores 58 (140): 99-117. 2009.We begin with an introductory overview of contributions made by more than twenty scholars associated with the Philosophy Department at the University of Buffalo during the last half-century to our understanding and evaluation of Aristotle’s logic. More well-known developments are merely mentioned in order to make room to focus on issues at the center of attention from the beginning: existential import and, more generally, the analysis of categorical propositions. I include a list of the UB schol…Read more

5The Absence of Multiple Universes of Discourse in the 1936 Tarski Consequence-Definition PaperIn Urszula Wybraniec-Skardowska & Ángel Garrido (eds.), The Lvov-Warsaw School. Past and Present, Springer- Birkhauser,. pp. 405-424. 2018.This paper discusses the history of the confusion and controversies over whether the definition of consequence presented in the 11-page Tarski consequence-definition paper is based on a monistic fixed-universe framework—like Begriffsschrift and Principia Mathematica. Monistic fixed-universe frameworks, common in pre-WWII logic, keep the range of the individual variables fixed as ‘the class of all individuals’. The contrary alternative is that the definition is predicated on a pluralistic multipl…Read more

14Logic in The 21st Century: Advice For Young LogiciansFelsefe Arkivi 51 309-319. 2019.By logic I mean the subject Aristotle started in Prior Analytics. Logic studies demonstration and everything necessary for demonstration, and also many things that come to mind in the course of such studies—including axiomatic method as described in my short “Axiomatic method”. By young I mean less than about 40 years old. By logicians I mean people who have dedicated their lives to advancing and criticizing logic: to discovering and establishing new additions and also to clarifying and correcti…Read more

16Aritmética Semántica: un prefacioAgora 39 (1). 2020.La teoría de números, o la aritmética pura, concierne a los números naturales mismos, no a la notación usada, y en particular no a los numerales. La teoría de ristras, o la sintaxis pura, concierne a los numerales como ristras de caracteres «no-interpretados», al margen de los números que puedan denotar cuando son usados. La teoría de los números es puramente aritmética, la teoría de ristras es puramente sintáctica… en tanto se considere el universo del discurso solo. La aritmética semántica es …Read more

36Deductions and Reductions Decoding Syllogistic MnemonicsEntelekya Logico-Metaphysical Review 2 (1): 5-39. 2018.The syllogistic mnemonic known by its first two words Barbara Celarent introduced a constellation of terminology still used today. This concatenation of nineteen words in four lines of verse made its stunning and almost unprecedented appearance around the beginning of the thirteenth century, before or during the lifetimes of the logicians William of Sherwood and Peter of Spain, both of whom owe it their lasting places of honor in the history of syllogistic. The mnemonic, including the theory or …Read more

42Aristotle’s Prototype Rule-Based Underlying LogicLogica Universalis 12 (1-2): 9-35. 2018.This expository paper on Aristotle’s prototype underlying logic is intended for a broad audience that includes non-specialists. It requires as background a discussion of Aristotle’s demonstrative logic. Demonstrative logic or apodictics is the study of demonstration as opposed to persuasion. It is the subject of Aristotle’s two-volume Analytics, as its first sentence says. Many of Aristotle’s examples are geometrical. A typical geometrical demonstration requires a theorem that is to be demonstra…Read more
