 Historically, it seems that counterfactual thinking as an approach to obligations was mainly rejected, but Swyneshed’s approach garnered some following. Both of these approaches appear to take issue with Burley’s principle that the order of propositions has crucial significance in how they are to be evaluated. Since Swyneshed’s way of rejecting this principle found some followers, this fact may signal that his approach was taken to be closer to what really is at issue in obligations as a genre of logic. However, generally speaking Burley’s approach became the mainstream towards the end of the fourteenth century. Perhaps, taking the order of propositions into account was taken to be less problematic than Swyneshed’s acceptance of contradictory triads.
