The discussion about what constitutes a “good argument” and when it is reasonable to accept a premise, clarifies that a good argument has 2 main criteria: true premises and a logical connection from those premises to the conclusion. A good argument must also be clear, relevant, complete, and fair. For instance, once a friend said “Most people never do exercise”, so I refuted her generalization by mentioning my lifestyle because I love doing exercise. In this way, it's important to note that, categorical logic is based on learning through statements or claims like “All mice are mammals” into standard form and to test syllogism with Venn diagrams. On the other hand, propositional logic shows us how to use connectors like: AND((^)(is true only if both parts are true)), OR((v) (is true if at least one part is true)), IF-THEN((→ )(is false only when the “if” is true and th “this n is false)), through truth tables.
