Experimental Reason and Disjunctive Reason

While the object of Doubt is some given circumstance, the object of the experimental question, 'What if?', is the subsequent proposal, the entertaining of which entails a doubt of the given only in the case of mutual exclusivity.  In other words, what questioning immediately effects is the generation of an alternative to some given.  Thus, the traditional Logical classification that best suits Experimental Reason is 'Disjunctive', i. e. Disjunctive Reason is the source of disjunctive propositions, and, hence, is presupposed by the Disjunctive Syllogism.
