In logic, a syllogism is a form of deductive reasoning consisting of a major premise, a minor premise, and a conclusion. Deductive reasoning begins with premises which are statements or assumptions on which an argument is based or from which conclusions are drawn. A major premise is a general statement that relates two terms. A minor premise is an example of the statement that was made in the major premise. The conclusion is supported by the premises. A syllogism is valid when its conclusion follows logically from its premises. A syllogism is true when the premises are consistent with the facts. To be sound, a syllogism must be both valid and true. Syllogism is being used by all of us every single day without we even noticing it.
My Example:
Major premise: All mammals are warm-blooded.
Minor premise: All dogs are mammals.
Conclusion: Therefore, all dogs are warm-blooded.
This syllogisms is sound because it is both valid and true. It is true because all mammals are warm-blooded (major premise) and all dogs are mammals (minor premise), which makes all dogs warm-blooded (conclusion.) This is valid because the conclusion follows logically from its premises. The major premise, minor premise, and conclusion are factual statements. Because of this the syllogism is true and valid, making it sound.
