Philosophy is a dark room.
Marxist philosophy is a black cat in a dark room.
It is a pleasant surprise to read a review of one's book, since you know that the reviewer is obliged to spend more time and effort on reading it than the average reader. In the future I intend to leave behind these authors and develop my own cognitive semiotics of film. While Petric clearly understands the origins and aims of my book, Grodal is led astray by his own agenda, for he criticises me for not including a discussion of himself, as well as the work of others, such as Ed Tan and Murray Smith. The fact that I do not see their work as emerging from Metz's film semiotics is the reason I did not discuss them in my book. I shall only comment on their review of these chapters.
