 This approach was not followed in later theories of obligationes. It may be that obligations were thought of as concerned with relations between propositions rather than building a description of a possible situation that could be imagined. The anonymous author’s approach requires the respondent to imagine what the situation would be like if the positum were true and give evaluations on the basis of that situation. Thus, the evaluations would not be based on the logical relations between the various propositions of the disputation itself. If obligational disputations were conceived as a tool for examining logical relations between propositions, such counterfactual thinking may not be the best way to proceed.
