LessonsAdvanced Applied Usul: Testing Evidence and Inference (Supplementary)Quiz

An analogy does not extend the rule of an original case because the two things share a color, price, or name. It requires a legally recognized effective cause common to both. If the proposed cause is not established, neat labels for the other elements do not rescue the inference.

Suppose someone argues: “Object A is red; B is red; therefore both receive the same religious ruling.” The missing step is evidence that redness is the operative cause. The appropriate response requests proof of the legally relevant attribute before drawing a conclusion.
