In Dylan Horrocks Inventing Comics: Scott McCloud’s Definition of Comics, he starts out with how McCloud defines comics. Horrocks says that McCloud uses the forms of comics to limit what it is that he has to talk about. When McCloud 'says this is comics', what he is saying is this is what comics should be, and what they should not be. Horrocks then talks about how McCloud does not give an accurate account for the history of comics, but only gives us the good, version of the history. McCloud uses Eisner’s idea of Sequential art as a element of comics, but never says why. Horrocks says that McCloud only uses this idea, because he likes it, and because it highlights what he likes about comics. Horrocks says that McCloud persuades us with the ideas usefulness. McCloud takes Eisner’s concept of sequential art, rewrites it as a dictionary-style definition, and renames it as comics. Horrocks says that McCloud uses this as another way to make things the way that McCloud wants to see them.
Horrocks states that Understanding Comics is full of geographical metaphors, and that McCloud uses diagrams and charts. His maps definition is an attempt to free comics from previous definitions that confined them. McCloud wants to claim more space for comics. McCloud then expands sequential art by excluding things that are not comics, such as animation, text only works, and single panel cartoons. This opened new territory for comics.
Horrocks says that McCloud only uses Eisner’s idea of sequential art because he likes it. Horrocks says McCloud likes the ideas because it shows everything that he favors about comics. If I were going to write a book on my favorite topic, I would obviously use something that would emphasize what I like about the topic, or about what was good about that topic. McCloud uses an idea that he thinks best fits what he wants to show, and uses it to his advantage. There is nothing wrong with that, especially if it is his book. What McCloud did with Sequential Art’s definition was apply it to what he needed to accomplish, and use it to get his point across.
