Document Summary
Week 3- well-formed arguments : argument analysis, the standard form of arguments. Standard form- particular form of an argument. An argument that has three premises will look like this: You are less likely to include extra material. Easier to spot areas with missing premises. Encourages clearer and more precise formulations of arguments. You can easily refer to premises/conclusion bc they are numbered. Argument analysis- extracting arguments from prose passages and putting them in standard form to decide whether they are good arguments or not. 2 steps: reconstructing the argument (rewriting argument in standard form) & evaluating the argument (decide whether outlined argument is good or not) Arguments can go wrong in two ways: It can have a conclusion that does not follow its premise. It can have a premise that isn"t true: well-formed arguments. Well-formed argument - any argument whose conclusion does follow from its premise.
