Bobzien, Susanne. Stoic Syllogistic
1996, Oxford Studies in Ancient Philosophy 14: 133-92.
Added by: Berta Grimau, Contributed by: Giada FratantonioAbstract: For the Stoics, a syllogism is a formally valid argument; the primary function of their syllogistic is to establish such formal validity. Stoic syllogistic is a system of formal logic that relies on two types of argumental rules: (i) 5 rules (the accounts of the indemonstrables) which determine whether any given argument is an indemonstrable argument, i.e. an elementary syllogism the validity of which is not in need of further demonstration; (ii) one unary and three binary argumental rules which establish the formal validity of non-indemonstrable arguments by analysing them in one or more steps into one or more indemonstrable arguments (cut type rules and antilogism). The function of these rules is to reduce given non-indemonstrable arguments to indemonstrable syllogisms. Moreover, the Stoic method of deduction differs from standard modern ones in that the direction is reversed (similar to tableau methods). The Stoic system may hence be called an argumental reductive system of deduction. In this paper, a reconstruction of this system of logic is presented, and similarities to relevance logic are pointed out.Export citation in BibTeX formatExport text citationView this text on PhilPapersExport citation in Reference Manager formatExport citation in EndNote formatExport citation in Zotero format
Chakravartty, Anjan. Introduction: Ancient Skepticism, Voluntarism, and Science
2015, International Journal for the Study of Skepticism 5 (2):73-79
Added by: Simon Fokt, Contributed by: Matthew WattsAbstract: In this introduction, I motivate the project of examining certain resonances between ancient skeptical positions, especially Pyrrhonism, and positions in contemporary epistemology, with special attention to recent work in the epistemology of science. One such resonance concerns the idea of suspension of judgment or belief in certain contexts or domains of inquiry, and the reasons for (or processes eventuating in) suspension. Another concerns the question of whether suspension of belief in such circumstances is voluntary, in any of the senses discussed in current work on voluntarism in epistemology, which informs recent discussions of how voluntarism regarding epistemic stances may shed light on positions like scientific realism and antirealism. The aim of this special issue is thus to explore certain analogies and disanalogies between ancient and contemporary debates about skepticism, and to consider whether and to what extent the former can provide insight into the latter.
Comment: This text offers motivation for examining ancient skeptical positions in relation to contemporary epistemology, especially epistemology of science.Export citation in BibTeX formatExport text citationView this text on PhilPapersExport citation in Reference Manager formatExport citation in EndNote formatExport citation in Zotero format

Comment: This paper can be used as specialised/further reading for an advanced undergrad or postgraduate course on ancient logic or as a primary reading in an advanced undergrad or postgraduate course on Stoic logic. Alternatively, given that the text argues that there are important parallels between Stoic logic and Relevance logic, it could be used in a course on Relevance logic as well. It requires prior knowledge of logic (in particular, proof theory).
