The Persian Jewish communities include the ancient (and until the mid-20th century still-extant) communities not only of Iran, but also the Azerbaijani, Armenian, Georgian, Iraqi, Bukharan, and Mountain Jewish communities. Jews who migrated to ancient Persia mostly lived in their own communities. In 586 BC, the Neo-Babylonian Empire expelled large populations of Jews from Judea to the Babylonian captivity. Persian Jews have lived in the territories of today's Iran for over 2,700 years, since the first Jewish diaspora when the Assyrian king Shalmaneser V conquered the (Northern) Kingdom of Israel (722 BC) and took some of the Israelites into captivity at Khuzestan. From "Our day in the light of the prophecy", 1921. Jerusalem is rebuilt by Cyrus, Darius and Artaxerxes. All fools are poets this the Prefect feels, and he is merely guilty of a non distributio medii in thence inferring that all poets are fools.Jews mourning over the ruins of Jerusalem.

This functionary, however, has been thoroughly mystified and the remote source of his defeat lies in the supposition that the Minister is a fool because he has acquired renown as a poet. The fallacy of the undistributed middle is referenced in Edgar Allan Poe's detective story The Purloined Letter: Grandfather is a student and thus carries a backpack In popular culture Again, note below that "student" is distributed: It is therefore distributed across the whole of its class, and so can be used to connect the other two terms (backpack carriers, and my grandfather). In this case, the middle term is the class of students, and the first use clearly refers to 'all students'. Therefore, my grandfather carries a backpack.However, if the latter two statements were switched, the syllogism would be valid: Specifically, the structure of this example results in affirming the consequent. Grandfather is someone who carries a backpack student is someone who carries a backpack Note below how "carries a backpack" is truly undistributed: Therefore, it can't be used to connect students and my grandfather-both of them could be separate and unconnected divisions of the class of backpack carriers. It is undistributed because neither of its uses applies to all backpack carriers. The middle term is the one that appears in both premises-in this case, it is the class of backpack carriers. Everyone who carries a backpack is a student.Therefore, my grandfather is a student.Indeed, from the perspective of first-order logic, all cases of the fallacy of the undistributed middle are, in fact, examples of affirming the consequent or denying the antecedent, depending on the structure of the fallacious argument. However, the fallacy may be resolved if the terms are exchanged in either the conclusion or in the first co-premise. The fallacy is similar to affirming the consequent and denying the antecedent. What is relevant to the conclusion is whether it is true that "all B is Z," which is ignored in the argument. It may or may not be the case that "all Z is B," but this is irrelevant to the conclusion. Where the premises are in the green box and the conclusion is indicated above them.ī is the middle term (because it appears in both premises), and it is not distributed in the major premise, "all Z is B". This may be graphically represented as follows: The fallacy of the undistributed middle takes the following form: The middle term-Z-is distributed, but Y is distributed in the conclusion and not in any premise, so this syllogism is invalid. B would be distributed by introducing a premise which states either All B is Z, or Some B is Z.Īlso, a related rule of logic is that anything distributed in the conclusion must be distributed in at least one premise. In this example, distribution is marked in boldface:ī is the common term between the two premises (the middle term) but is never distributed, so this syllogism is invalid. The fallacy of the undistributed middle occurs when the term that links the two premises is never distributed. The first term is distributed in A statements the second is distributed in O statements both are distributed in "E" statements, and none are distributed in I statements.

In classical syllogisms, all statements consist of two terms and are in the form of "A" (all), "E" (none), "I" (some), or "O" (some not).
