Study Notes
Propositions and Arguments
- A proposition does not automatically qualify as an argument; an argument requires inference from premises to a conclusion.
- Arguments can be supported in two ways:
- Total support from premises
- Partial support with some degree of probability
Types of Arguments
- Deductive Arguments:
- Premises provide conclusive support for the conclusion.
- If premises are true, the conclusion must be true.
- Inductive Arguments:
- Premises provide probable support for the conclusion.
- If premises are true, the conclusion is likely to be true.
Key Concepts
- Premises: Statements that provide grounds or reasons to support a conclusion.
- Conclusion: The statement affirmed based on premises, regarded as the outcome of the logical reasoning process.
- An argument consists of a structured relationship between premises and conclusion.
Validity and Truth
- An argument is valid if the conclusion logically follows from the premises.
- Truth and validity are distinct concepts; an argument can be valid but have false premises.
Learning Outcomes
- Ability to distinguish between deductive and inductive arguments.
- Providing examples for both argument types.
- Understanding validity, invalidity, and the relationship between truth and validity.
Additional Types of Logic
- Types of Logic: Investigates various logical frameworks underpinning arguments and reasoning.
- Inductive and deductive reasoning are foundational concepts explored across the broader study of logic.
Assumptions for Arguments
- An argument lacks structure if there is no logical relationship between the premise(s) and conclusion.
- Arguments may range from simple two-sentence forms to complex multi-statement constructions.
Fundamental Laws in Logic
- Law of Identity: A statement is identical to itself (A is A).
- Law of Contradiction: A proposition cannot be both true and false at the same time.
