Abstract
Susan Stebbing held that Russell’s Doctrine of External Relations was incorrect. Interestingly, she also held that Bradley’s Doctrine of Internal Relations was problematic. In this paper, I’ll explain why she held this position, and develop what I will call the Doctrine of I/E relations, which will explain her middle ground. I start with a brief explanation of Russell’s Logical Atomism and his commitment to the Doctrine of External Relations. Then, to explain the Doctrine of I/E Relations, I take a brief detour through Stebbing’s theory of directional analysis. This will allow us to conclude by presenting the new Doctrine.
