Now we make some small changes in the way we do argument diagrams, due to the importance of complex statements in reasoning. The changes are to allow for disjunctions, conditionals, and pairs of opposites. Put brackets around the statements and circle the inference indicators. Doing a skeleton is not necessary, but it is advisable for complicated arguments. In complicated arguments, a skeleton can be very helpful for detecting the overall structure of the argument.
Diagrams are only for passages that contain arguments.
If an argument is present, do a diagram.
