Document Summary
Recall we represent arguments with a numbered list of premises, an inference marker (a line), and a numbered conclusion. Standard form (sf: p1, pn . n + 1 conclusion (from 1-n) Sub argument (based on 1 & 2, for 3) and main conclusion. Going from a text to an argument in sf is not trivial. Tangents (talking about something that isn"t relevant to what they"re arguing for), repetition (doesn"t do anything to an argument), guarding terms (someone weakens what they"re saying, e. g. all vs. some doctors), assurances (citing expert opinions. E. g. clearly doesn"t add anything, when we"re writing out the argument writing out the word has no purpose) are usually not required to represent the core premises and conclusion of an argument (although people use them frequently) We want to represent arguments in the best possible light-to present the more rigorously than the authors sometimes do themselves.
