 The first five hundred years of the common era also saw the redaction of philosophical treatises in which proponents of diverse philosophical and religious traditions put forth systematic versions of their world views. These latter works bear witness, in a number of different ways, to the intense interest in argumentation during this period. Among the diverse forms of argument from this period, one emerges as a canonical one. In this section, we first review the texts relevant to the development of logic from the end this preclassical period. We then turn our attention to surveying the emergence of a canonical argument form. Finally, we conclude with a very brief overview of the treatment of fallacies in arguments and of missteps in debate.
