DIAGRAM 10R. Ishmael’sRule No. 13, the last in his list, covers many different cases, most of which cannot readily be illustrated. However, the following diagram illustratesone exampleof the dialectic often involved, where thesis and antithesis are both narrowed, and replaced by their synthesis or common ground.Diagram 10This illustration is symbolic, note well, because strictly speaking [...]

JL Diagram 9

DIAGRAM 9R. Ishmael’sRule No. 11 – “…lidon badavar hechadash”– can also to some extent be represented graphically. Do not refer in the present case to the earlier common premises and conclusions (for Rules 8-10) – this is an entirely different situation. Here, we are initially given the premises:All S1 are P1andAll S2 are P2And we [...]

JL Diagram 7

DIAGRAM 7R. Ishmael’sRule No. 10 – “shelo kheinyano”– is difficult to depict since it concerns a conflict resolution. Its fourth premise is:No P1 is P2/ No P2 is P1 (predicatal premise).As the following first diagram shows this premise is in conflict with the others, since if the circles representing P1 and P2 cannot overlap at [...]

JL Diagram 6

DIAGRAM 6R. Ishmael’sRule No. 8(b) – “lelamed hefekh hadavar”– the particularizing version of “lelamed”, may be depicted as follows, since its fourth premise is (note the reversal of order of the terms, in comparison to the preceding case):All P1 are P2(predicatal premise).Diagram 6The four premises formally yield the conclusion “All S1 are P2” (etc.).Yet R.
