In the chapter 8, Epstein talks about how to check whether certain kinds of arguments that use general claims are valid? We can check the validity with diagrams which includes:
1) A collection that is represented by an enclosed area.
2) If one area is entirely with one another, then everything in one collection is also in other.
3) If two areas overlap another, then there is something that is common to both selections.
4) If two areas do not overlap, then there is nothing common to both collections.
5) An “a” or a do n area marks that a particular object is in that collection
6) Then we draw the areas to show the premises as true while trying to represent the conclusion is false. If we are able to represent the premises as true and conclusion is false then the argument is invalid. If there is no way to show the premises is true and conclusion is false then the argument is valid.
