What Is Logic?
Logic refers to a structured system of rules used to determine whether conclusions follow correctly from given information. It focuses on consistency, structure, and validity.
- Concerned with formal structure
- Examines whether arguments are valid
- Often used in maths, science, and problem-solving
Example: If all birds have wings and a sparrow is a bird, then a sparrow has wings.
What Is Reason?
Reason refers to the ability to think, understand, and form judgments. It is broader than logic and includes weighing evidence, context, experience, and practical considerations.
- Concerned with judgment and understanding
- Uses logic but also context and experience
- Common in everyday decision-making
Example: Choosing the best option based on facts, time limits, and likely outcomes.

Logic vs Reason in Everyday Life
- Logic checks whether conclusions follow correctly from facts.
- Reason helps decide what to do with those conclusions.
