44
Guidelines for restructuring an argument
1. List the premises first (labeled P sub1,Pv2…) and the conclusion labeled C last 2. Write the premises and conclusion in the form of separate declarative sentences 3. Eliminate all premise and conclusion indicators 4. Compound arrangements of statements in which the various components are all claimed to be true will be considered separate statements 5. Omit statements that are neither premises nor conclusions

An arrow a from one number (1) to another (2) means…
That statement 1 supports statement 2
47
Conjoint premises: two or more statements (1) and (2) are conjoint premises for a conclusion (3)…..
If taken separately they provide little or no support for (3), but taken together they do provide support. A single arrow from a brace encompassing 1 and 2 to 3 indicates this
48
Independent premises: 2 or more statements (1),(2),(3),(4) are independent premises for a conclusion (5) if….
Each would continue to support 5 in a he same way were the others omitted. Separate arrows from different group of numbers indicate independent premises
49
Multiple conclusions: when a statement (1) supports more than one conclusion (2) and (3)
An arrow goes from (1) to a brace encompassing both 2 and 3
50
