This is not an easy book but as introductions go, it isn't at all bad. I go further, it is a decent intro and I recommend it. Not that you won't find some passages difficult - they are - but bear with him and you can begin to see why Lacan is taken seriously by people who are assuredly not fools. It is a stimulating account of the notion of The Gaze, the Symbolic and his other conceptual armature and applies it rather well to art...in fact though at times I thought, "Blimey, he's making heavy weather of this" on other occasions I thought he/Lacan is really onto something. As indeed he/Lacan might well be ('Scuse me, I am British, thus not of a ready theoretical bent, more's the pride). Worth a few hours of your life very definitely, if only to demonstrate that Lacanian analysis ain't your 'bag'. Unless, of course, it is.
