$title = "Constructing the Categorical Converter - 2"; //
SP propositions are related by the rule of Conversion to PS propositions. Moreover, it is possible to construct a second Square for PS propositions.
The image is constructed in two stages. First, we add the PS Square and draw lines to represent straightforward conversions among I and O propositions (upper diagram, right).
Then we add the more complex conversions
between A and I propositions
(lower diagram, right). Note that these
are limited case conversions, being
equivalent to the combination of a
Subalternation and Conversion.
