Institutio Oratoria

In the schools, on the other hand, such an enquiry is mere waste of time, since the prosecution and the defence are indifferently permitted to state a case and refute it in the same declamation. But in the majority of controversial themes it is not even possible to discover who should speak first, as for instance in the following:

A certain man had three sons, an orator, a philosopher and a physician. In his will he divided his property into four portions, three of which he distributed equally among his sons, while the fourth was to go to the son who rendered the greatest service to his country.

The sons dispute the point. It is uncertain who should speak first, but our course is clear enough. For we shall begin with the son whose role we assume. So much for the general rules by which we should be guided in making our division.
