Mahdi Azimi

Volume 14, Issue 2 , January 2024

https://doi.org/10.30465/lsj.2024.48173.1461

Abstract
  Aristotle gives a definition of "universal" that Łukasiewicz considers non-comprehensive because it does not include null universals. In addition, Aristotle's definition of a particular can be understood in two ways: (1) a particular can only be predicated on one thing, (2) a particular cannot be predicated. ...  Read More

https://doi.org/10.30465/lsj.2019.5171

Abstract
  In Priori Analytics, II. 25, Aristotle proposes a sort of reasoning called apagpge. Scholars differ about its translation, definition, and formulation.

https://doi.org/10.30465/lsj.2019.4151

Abstract
  Suhrawardi claims that there can be no one-premissed syllogism, and he makes a reason for this.

Our hypothesis is that, historically, the conflict over the possibility or impossibility of the one-premissed ...  Read More

Topoi in Avicenna’s Logic; From Strategies of Debate to Fallacies of Definition

Mahdi Azimi

Volume 4, Issue 2 , September 2013, , Pages 113-142

Abstract
  Aristotle and Peripatetics used topoi as the strategies of debate, but Avicenna changed their function to the fallacies of definition. This is one of his outstanding innovations to which the modern scholars didn’t pay attention. This innovation, on one hand, is related to Avicenna’s logical ...  Read More

Mahdi Azimi

Volume 2, Issue 1 , March 2011, , Pages 85-102

Abstract
  In his Isagoge, Porphyry provides circular definitions for genus and species; and to justify this point, following Aristotle, he attaches emphasis to correlation between the two concepts and that the definitions for two correlative concepts should be circular. Ibn Sina, however, interprets Aristotelian ...  Read More
