Logic is the study of reasoning and argumentation. It involves analyzing and evaluating arguments to determine whether they are valid or sound. In logic, arguments are made up of premises (statements that are assumed to be true) and a conclusion (a statement that follows from the premises). The goal of logic is to determine whether the conclusion logically follows from the premises.
According to the Stanford Encyclopedia of Philosophy, logic is "the study of the principles of correct reasoning." It is a fundamental branch of philosophy that is concerned with the principles of valid reasoning and inference. Logic is used in various fields, including mathematics, computer science, and philosophy, to analyze and evaluate arguments and to make sound decisions.
In his book "Introduction to Logic," Irving M. Copi defines logic as "the study of the methods and principles used to distinguish correct reasoning from incorrect reasoning." This definition emphasizes the importance of logic in distinguishing between valid and invalid arguments.
Overall, logic is a systematic and rigorous discipline that is concerned with the principles of correct reasoning and argumentation. It provides a framework for analyzing and evaluating arguments to determine their validity and soundness.

Meaning of Logic
Logic is the study of correct reasoning and argumentation. It provides a framework for evaluating the validity of arguments and ensuring that conclusions follow logically from premises. The term "logic" derives from the Greek word "logos," originally meaning "word" or "thought."
Key Concepts in Logic
- Argument: A set of statements that presents reasons (premises) for a conclusion.
- Premise: A statement that supports the conclusion.
- Conclusion: The statement that is inferred from the premises.
- Validity: An argument is valid if its conclusion follows logically from its premises.
- Soundness: An argument is sound if it is both valid and has true premises.
Types of Logic
There are several branches of logic, including:
- Deductive logic: Analyzes arguments that guarantee the truth of their conclusions if the premises are true.
- Inductive logic: Examines arguments that provide probable conclusions based on evidence.
- Modal logic: Deals with the logical properties of possibility, necessity, and other modalities.
- Symbolic logic: Uses symbols and formal rules to represent arguments and evaluate their validity.
Significance of Logic
Logic is essential in various fields, including:
- Philosophy: Provides a basis for understanding how reasoning works.
- Science: Helps researchers evaluate the validity of hypotheses and theories.
- Computer science: Enables the design of logical circuits and artificial intelligence systems.
- Law: Assists in legal reasoning and the interpretation of contracts and laws.
- Everyday life: Guides us in making sound decisions and resolving conflicts.
