Wow, not exactly what I expected when I went looking for Zizek on YouTube--he is a wild man! In this clip, he comes to the conclusion that love is violent, love is evil, which isn't so different from McLuhan's argument that education is violent, education is war and war is education.
I did some database searching today, and very few scholars are making a McLuhan-Zizek connection, which may or may not be significant. Both are a little to hot (by which I mean cool) to handle, so they don't seem to get a lot of application. McLuhan far outstripped Zizek on my database quests--how did the guy get to be such a name if so few people use him?
