Quran and Sunnah Perspective on Informal Logical Fallacies
This research is aimed at providing critical appraisal of some informal logical fallacies from the Quran and Sunnah. The fallacies are defined adequately, analyzed logically, understood conceptually, and then criticized from Islamic perspective based on the Quran and Sunnah. First some fallacies of relevance are undertaken. Argumentum ad Hominem (Argument Directed at the Person) according to Islamic perspective is valid in respect to transmitted knowledge (uloom naqliah); on the other hand, this fallacy is invalid in respect to rational knowledge (uloom aqliyah) in inclusion of empirical knowledge (uloom tajribiyah). Argumentum ad Populum (Appeal to the People) fallacy according to Islamic perspective is accepted as a valid fallacy if what someone, elite, or majority hold is against the evidences and facts. However, in terms of keeping law and order in a society, Islam encourages the concept of Shura (consultation and group decision) and jamaah (unity and group) to make it possible that among many good options, Muslims would be able to follow any one with majority agreement to get over any disagreement or conflict. Among fallacies of presumption, some fallacies were undertaken as follows. Secundum quid (Fallacy of Hasty Generalization) is accepted fallacy according to Islamic perspective. The Islamic spirit is against hasty generalizations. Argumentum ad Verecundiam (Argument from Authority) is an accepted fallacy according to Islamic perspective. Islam emphasizes on evidence and proof in accepting or negating any fact. This is primary. However, proper authorities should be consulted on matters, this is what the Quran and Sunnah encourages.
