Definition: In logic, a form of deductive reasoning consisting of a major premise, a minor premise, and a conclusion. Adjective: syllogistic. Here is an example of a valid categorical syllogism: Major premise: All mammals are warm-blooded. Minor premise: All black dogs are mammals. Conclusion: Therefore, all black dogs are warm-blooded. In rhetoric, an abridged or informally stated syllogism is called an enthymeme.
The law of syllogism, also called reasoning by transitivity, is a valid argument form of deductive reasoning that follows a set pattern. if a = b and b = c then, a = c. There are also three parts involved in the law of syllogism, and each of these parts is called a conditional statement. A conditional statement has a hypothesis, which follows after the word if, and it has a conclusion, which follows after the word then.
