Syllogism deductive reasoning

One of the most common types of deductive reasoning is syllogism. Syllogism refers to two statements—a major and a minor—joining to form a logical conclusion. The two accurate statements mean that the statement will likely be valid for all additional premises of that category.

What makes a strong and valid argument?

What is a true argument?

TRUE: If an argument is sound, then it is valid and has all true premises. Since it is valid, the argument is such that if all the premises are true, then the conclusion must be true. A sound argument really does have all true premises so it does actually follow that its conclusion must be true.

What is an unfounded argument?

: lacking a sound basis : groundless, unwarranted. an unfounded accusation.

What types of arguments are valid?

How do you prove an argument is not valid?

We can prove that an argument is invalid by finding an assign- ment of truth values to the propositional variables which makes all the premises true but makes the conclusion false. We call such an assignment a counterexample . To disprove the validity of an argument you should always provide a counterexample.

Does a good argument have to be valid?

A good argument is one where the premises provide strong reasons to believe in the truth of the conclusion. That means that a good argument: if it is a deductive argument, it should be sound (and, therefore, also valid);
