In Economic Origins of Roman Christianity , as in their earlier works, Robert B. Ekelund, Jr., and Robert D. Tollison propose the forcing of history into the once-favored rational-agent template of economics, as an aid to a better understanding. Their terminology of choice amounts to translation, applied in a novel way. In the circle of Ekelund and Tollison, this approach has given rise in recent decades to an active social-scientific sub-specialty. Since, however, in translation much is lost, why resort to it as a tool of science?
