Document Summary

Revise and improve until you have a clear and concise version of the argument that states the argument the best possible way. Compound argument consists of several sub arguments. Unnecessary premise a premise that is not needed to justify the conclusion. Direct justification a premise offers direct justification for an conclusion if it appears in the list of steps justifying the conclusion. Indirect justification a premise offers indirect justification for a conclusion when it justifies some other premise that itself either directly or indirect justifies the conclusion. Common mistakes in argument reconstruction: (1) improper wording. Since most people who study hard will do well in school, it"s likely that jim will do well. First attempt: most people who study hard will do well in school, jim studies regularly. Two better possibilities: most people who study hard will do well in school, jim studies hard.
