Study Notes
Key Concepts in Logic and Critical Thinking
- Argument: A set of propositions where the truth of one (the conclusion) is supported by the truth of others (the premises).
- Conclusion: The proposition in an argument that is intended to be supported by the premises.
- Premises: Propositions in an argument meant to provide support to the conclusion.
Types of Arguments
- Deductive Argument: An argument where if the premises are true, the conclusion must be true.
- Valid Deductive Argument: A deductive argument where it is impossible for the premises to be true while the conclusion is false.
- Invalid Deductive Argument: A deductive argument that allows for the premises to be true while the conclusion is false.
Characteristics of Deductive Arguments
- Sound Deductive Argument: A valid argument with all true premises.
- Unsound Deductive Argument: An argument that is either invalid or has at least one false premise.
Inductive vs. Deductive Arguments
- Inductive Argument: An argument where the premises support the conclusion in terms of likelihood, meaning if the premises are true, the conclusion is more likely true than false.
- Primary Difference: Deductive arguments provide necessity for the conclusion based on the premises, while inductive arguments provide a probability that the conclusion is true.
Types of Inductive Arguments
- Strong Inductive Argument: An argument where the premises, if true, make the conclusion more likely true than false.
- Weak Inductive Argument: An argument where the premises do not provide enough support for the conclusion, making it equally likely to be true or false.
Evaluating Inductive Arguments
- Good Inductive Argument: Both strong and has all true premises.
- Bad Inductive Argument: Either weak or contains at least one false premise.
Overall Criteria for Arguments
- Good Argument: Can be assessed as either a sound deductive argument or a good inductive argument.
- Bad Argument: Contains at least one false premise or, even with all true premises, does not make the conclusion more likely to be true than false.
