He has floating paper and floating pencils and he is on a MISSION. Which does involve snuggles.
Venn diagrams don't capture the whole way his argument works, because they're sort of backwards—they're good for "here are things like X, and things like Y, and things that are both like X and like Y are Z" but not so much for "here are X and Y, these are the things in them that are like each other versus not"—but they're a good starting point for him to begin developing his own thing.
In the analogy between the wielder of a knife and him and the knife itself and also him, there are five main axes of interest: the comparison between the wielder and the first him, the knife and the second him, the wielder and the knife, the first him and the second him, and the relationship between wielder and knife and the relationship between him and him. Some are obvious, some are not.
Listing them all is possible, but probably not really feasible, and this suggests something else: expand his analogy space. Find other things that are like the way the first him and the second him are and which are different from the knife and wielder example, and then compare those. Then instead of listing everything he can list only a subset of everything for each comparison and then try to rely on common sense differences and similarities to do the rest of the work.
He is going through a lot of paper.
