I think a better title would be Dark Arts: A Case Study. I came here expecting a lesson in how to use the Dark Arts. But a lesson should consist of more than just pointing out an example, broader arguments and suggestions need to be made.

It is not here because the book is important; it's here because it describes an example of a deceptive persuasive technique.

You talk a lot about Steiner's use of the deceptive technique, but not a lot about the technique in general. I feel it would be better if you talked about the technique in general, how to recognize when it's drawing you in, other cases where it is used, things like that. A specific instance of Dark Arts by itself is not a noteworthy occurrence, the Dark Arts are used all the time across the planet.
