GENERAL CONDITIONALS IN STOIC LOGIC

Miguel Lopez Astorga

 

Abstract:

It is often thought that Stoic logic is only a particular constatival logic. In this paper, I will try to show that this idea is not correct and that the Stoics addressed at least general conditionals. To do this, I will take into account arguments such as those raised by Josiah B. Gould, W. H. Hay, and Robert R. O’Toole and Raymond E. Jennings. Likewise, I will propose that, if the concept of “Feeder schemata”—conjunction introduction and elimination rules—of the mental logic theory is considered, the points or aspects that are unclear in the ancient sources can be easily understood.
