Study Notes
Valid Arguments
- Valid arguments ensure that if the premises are true, the conclusion must also be true.
- Even if premises are false, a valid argument can still maintain coherence in logic.
Sound Arguments
- Sound arguments require that all premises are true, leading to a true conclusion.
- All sound arguments are also valid, but not all valid arguments are sound.
Example of a Valid Argument
- Argument structure:
- Premise 1: Socrates is a frog.
- Premise 2: All frogs are mortal.
- Conclusion: Socrates is mortal.
- Despite the false premise (Socrates being a frog), the argument's logic remains valid.
Example of a Sound Argument
- Argument structure:
- Premise 1: Socrates is a man.
- Premise 2: All men are mortal.
- Conclusion: Socrates is mortal.
- Both premises are true, confirming the conclusion as true and illustrating a sound argument.
