Formal logic is a branch of logic that deals with the formal rules of inference and deduction, typically using symbols and mathematical notation to represent logical relationships. It is concerned with the validity of arguments based on their structure and form, rather than the content of the statements being made.
Informal logic, on the other hand, is concerned with the analysis of arguments in natural language, without the use of formal symbols or mathematical notation. It focuses on the content of the arguments, including the premises and conclusions, as well as the reasoning and evidence used to support them. Informal logic is often used in everyday communication and reasoning, such as in debates, discussions, and persuasive writing.

Formal Logic
- Definition: A system of reasoning that follows strict rules and symbols to derive conclusions from premises.
- Characteristics:
- Precise: Uses well-defined symbols and rules.
- Deductive: Conclusions are guaranteed to be true if the premises are true.
- Objective: Not influenced by personal biases or context.
- Examples:
- Mathematical logic
- Propositional logic
- Predicate logic
Informal Logic
- Definition: A type of reasoning that uses everyday language and common sense to draw conclusions.
- Characteristics:
- Imprecise: May use ambiguous language and rely on assumptions.
- Inductive: Draws general conclusions from specific observations, but may not guarantee the truth of the conclusion.
- Subjective: Can be influenced by personal biases and context.
- Examples:
- Common sense reasoning
- Everyday decision-making
- Persuasive arguments
- Fallacies
Key Differences
| Feature | Formal Logic | Informal Logic |
