The 12th volume of Freud's collected works, this is well worth a read for those who are interested in studying sociology or psychology. Linguistically it is fairly dense at times, at least for those who have not read critical texts to this caliber before hand.
I personally found his part scientist part sociologist viewpoint to be very effective and instigates an informative critique of the society that we in the west call home, perhaps hitherto taking for granted, primarily from an objective perspective and thus allows for you to chew on the meal that he outs forward for you to digest...
Freud has helped me to understand and appreciate a great deal more about the way that we as human beings have operated, in a historical and modern day reflection.
One of the most worthwhile books I have read on this subject, certainly giving justice to the claim of Freud being the monumental critical figure that he was and remains within literature.
