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.
