    Mathematician: this is category theory. No, it didn’t have anything to do with categorization, it just helps us understand how spaces can map to each other. Yeah I guess it’s kinda like graph theory or algebra, but not really. We made a category of graphs, and you can use the category of graphs to represent endofunctors on the category of categories.

      – It’s about nothing.

      – No sets?

      – No, forget the sets.

      – You’ve got to have sets.

      – Who says you’ve got to have sets? Remember when we were talking about functions of functions? That could be a theory all by itself.
