What do the premises of an argument do?
- They support/provide reason to believe the conclusion
- You can infer the conclusion from the premises
What is the difference between an argument and an explanation?
An argument provides reasons for believing something and an explanation tells you why such and such is the case
Define validity
- The conclusion follows from the premises, whether or not the premises are true
- Concerns the relationship between the propositions, rather than the individual propositions themselves
Define soundness
- If it is valid and the premises are true and by consequence the conclusion, then it is sound
- If an argument is not valid then it cannot be sound
Define cogency
- An argument can be sound yet fail to persuade because the premises aren’t evidently true
- It is relevant to the audience
Define a necessary condition
A condition that is needed for something to be true
Define a sufficient condition
Something is enough for the outcome to occur, the truth of P guarantees the truth of Q
