Document Summary

The selling of human organs such as heart, kidney and corneas, should be outlawed (1). This one if one of the claims is not valid then it breaks the chain. If you doubt and prove 4 wrong then nothing follow but if you prove something in the middle wrong it doesn"t do anything. Two is not evidence for three and three is not evidence of two but they have to conjoin to produce evidence for the conclusion. Neither of them prove each other they are just joined to prove something because. 1 cannot be proved with 2 only and 1 cannot be proved with 3 only because these claims cannot get to the conclusion without each other. We ask that when analyzing an argument structure. A word or a phrase is vague if we cannot say with certainty what it includes and what it excludes. An arguments with vague terms can be disappointing.
