LOGICAL FALACY_ Documented by Marsigit

Logical fallacy


The argument presupposes its conclusion: one of the premises assumes that the conclusion is true. An argument that begs the question should not convince anyone. 

In the opposite direction is the fallacy of argument from authority. A classic example of this is the Ipse dixit — "He himself said it" — used through the Middle Ages in reference to Aristotle. A modern use is "celebrity spokepersons" in advertisements: that product is good because your favorite celebrity endorses it. 

While an appeal to authority is always a logical fallacy, it can be an appropriate rational argument if, for example, it is an appeal to expert testimony—a type of inductive argument

By definition, logical fallacies are invalid, but they can often be written or rewritten so that they follow a valid argument form; and in that case, the challenge is to discover the false premise, which makes the argument unsound.

    berdassarkan artikel di atas dapat saya pahami bahwa menurut definisi, kesalahan logis tidak valid, tetapi mereka sering dapat ditulis atau ditulis ulang sehingga mereka mengikuti bentuk argumen yang valid; dan dalam hal itu, tantangannya adalah untuk menemukan premis palsu, yang membuat argumen tidak sehat.
