The previous post illustrated a Rationale Path Map using a vertical convention for linking the co-premises. A horizontal transitive inference path is, perhaps, even easier to construct with Rationale. With this visual convention, the linkage of each co-premise along the inference path is obvious as the predicate of one co-premise becomes the subject of the next co-premise. From one perspective, this structure can be considered a strict construction of the rule of “Holding Hands.” And the inference steps through the process of substitution by the subject of the main contention (e.g. “Robinson”) to reach its predicate is easily observed and explained.
