FAQs on Syllogism - 5 Video Lecture - Logical Reasoning (LR) and Data Interpretation (DI) - CAT

1. What is a syllogism and how is it used in logic?
Ans. A syllogism is a form of deductive reasoning that consists of two premises and a conclusion. It is used in logic to analyze and evaluate arguments based on their structure and validity. The two premises in a syllogism are statements or propositions, and the conclusion is derived from the relationship between these premises.
2. What are the three main components of a syllogism?
Ans. The three main components of a syllogism are the major premise, minor premise, and conclusion. The major premise is a general statement or proposition, the minor premise is a specific statement related to the major premise, and the conclusion is the logical inference drawn from the two premises.
3. Can you provide an example of a syllogism?
Ans. Sure! Here's an example of a syllogism: Major premise: All mammals are warm-blooded animals. Minor premise: Elephants are mammals. Conclusion: Therefore, elephants are warm-blooded animals.
4. How is validity determined in a syllogism?
Ans. The validity of a syllogism is determined by its logical structure and adherence to the rules of deductive reasoning. In order for a syllogism to be valid, the conclusion must necessarily follow from the premises. This means that if the premises are true, the conclusion must also be true. Validity is independent of the actual truth or falsity of the premises.
5. What is the difference between a valid and an invalid syllogism?
Ans. A valid syllogism is one where the conclusion necessarily follows from the premises, based on the rules of deductive reasoning. If the premises are true, the conclusion must also be true. On the other hand, an invalid syllogism is one where the conclusion does not necessarily follow from the premises, even if the premises are true. In an invalid syllogism, the logical connection between the premises and the conclusion is flawed.
