Document Summary
A good argument is one whose premises support the conclusion (an argument that is either valid or cogent) And whose premises ought to be believed (by the audience in question). example: some public transit buses come up the mountain to sfu almost every day that is not a holiday. True: tomorrow is a day that is not a holiday. True: therefore, some public transit buses will come up the mountain to sfu tomorrow. Furthermore, since its premises are reasonable for us to believe, we should judge this to be a good argument. However, the fact that the above argument is cogent, together with the fact that it is reasonable for us to accept its premises, does not imply that it is reasonable for us to accept its conclusion. We might know that there is a transit strike planned for tomorrow, say, and htat bus service to sfu will almost certainly bve suspended.
