CATEGORICAL SYLLOGISM

Just as the verbal expression of the IDEA is the TERM, and that of the JUDGMENT is the PROPOSITION, so the verbal expression of DEDUCTIVE REASONING is called ARGUMENTATION. ARGUMENTATION is a discourse which logically deduces one proposition from other propositions. ARGUMENTATION takes the form of a SYLLOGISM. A SYLLOGISM is defined as any argumentation in which, from two propositions called the PREMISES, we conclude a third proposition called the CONCLUSION, which is so related to the premises jointly, that if the premises are true, the conclusion must also be true.
A SYLLOGISM derives its name from the kinds of propositions composing the syllogism. A SYLLOGISM is called CATEGORICAL if all the propositions composing the syllogism are CATEGORICAL PROPOSITIONS ( the predicate is affirmed or denied of the subject outright without any condition ). Example: All fathers are male parents. No true sportsman is a cheater.
A SYLLOGISM is called HYPOTHETICAL if all the propositions composing the syllogism are HYPOTHETICAL PROPOSITIONS ( two propositions united into one, where one can only be true if the other is false or vice-versa ). Example: If it rains, then the ground is wet. You cannot be a saint and a sinner at the same time. A matter is either in motion or at rest.

    In the world today, the word “argument” is used on a daily basis and usually carries a bad meaning. In fact, the word is used so much that people often mistaken it’s true meaning. According to the book Writing Arguments by John Ramage, John Bean and June Johnson, there is no universally accepted definition of “argument.” The meaning of the term is rather complex, and it has been remained a controversial issue of philosophers and rhetoricians over the centuries (2). Because of the complexity of the word, we need to examine three important points in order to understand what “argument” truly meant: the misconceptions about the meaning of argument, the features of argument, and the relationship of argument to the problem of truth.…

    It consists of a group of statements with one or more statements (premises) supporting another statement (conclusion). In Critical Thinking, argument is an act of presenting reasons to support individual’s position or point of view. It is not quarrel or dispute. By "argument," we mean a demonstration or a proof of some statement, not emotional language. E.g., "That bird is a crow; therefore, it's black."…

    An enthymeme is more useful than a syllogism in analyzing and constructing arguments because an enthymeme is used in real-world argumentation. Whereas, a syllogism is used primarily in a logic course. Enthymemes, being a shortened version of a syllogism, uses an unstated principal that you can understand without it being said. Later in the argument you can address the unstated principal to support your enthymeme.…

    o far we have looked at how to construct arguments and how to evaluate them. We’ve seen that arguments are constructed from sentences, with some sentences providing reasons, or premises, for another sentence, the conclusion. The purpose of arguments is to provide support for a conclusion. In a valid deductive argument, we must accept the conclusion as true if we accept the premises as true. A sound deductive argument is valid, and the premises are taken to be true. Inductive arguments, in contrast, are evaluated on a continuous scale from very strong to very weak: the stronger the inductive argument, the more likely the conclusion, given the premises.…

    The Dicto Simpliciter Fallacy is and argument based on an unqualified generalization. Contradictory Premises fallacy is when the premises of an argument contradict each other. Ad Misericoriam I thought was a little like Red Herring (aka Straw Man). In the story the author gave an example of how a man went for a job interview, and when asked for his qualifications, he gave him a sympathy speech. It was almost like he avoided the subject at hand. The next fallacy, Hypothesis Contrary to Fact, is when you have an untrue hypothesis and then supportable conclusions are drawn from this false hypothesis. The last fallacy learned in the story was Poisoning the Well. This was like making a generalization before anything has even happened for you to assume that.…
