Document Summary

Arguments with missing premises: if tuition fees continue to rise, i won"t be able to afford to go to school. I"m telling you: school will soon be unaffordable. Arguments with a missing conclusion: if atheism were true, there would be on such thing as objective right and wrong. I was in jail when he was killed! . ** remember: always follow the principle of charity. A three-step procedure for finding implicit premises: search for a credible premise that would make the argument deductively valid. Try to find a premise that: is plausible, and, best fits with the author"s intent (principle of charity) If you cannot think of one, proceed to the next step: search for a credible premise that would make the argument inductively strong. If you cannot find one, then reject the argument: if you were able to reconstitute the argument in steps 1 or 2, then evacuate it: determine whether it is sound or cogent.
