  Next the construction of the argument: Fallacies and sophisms were generally presented by means of an example which stands in for the general case, and it is plausible that this was so for the Master Argument as well. Overall, the argumentation then proceeded as follows: you assume of a chosen proposition that it neither is nor will be true; next, by employing (I), (II), (V) and (VI), you deduce that this proposition is impossible. Then you generalize the result to all propositions, since nothing in the argument hinges on the fact that this particular proposition was selected. A suitable example can be found in Alexander's passage on Diodorus' notion of possibility and the Master Argument: the proposition ‘I am in Corinth.’ The argument then starts with the assumption that
