"I noticed David's comments on crowds yesterday in relation to Facebook and this prompts me to ask about a book you have referred to in the past; Freud's "Psychology of Crowds". I have been unable to find that title although there are other books by Freud which deal with the subject. Can you give me the exact title of the book you have referred to please? Thanks for your service"

Eoin Treacy's view Thank you for this email which I'm sure others will be interested in. The book in question is Sigmund Freud's "Group Psychology and the Analysis of the Ego". I have read it many times and discover new subtleties on every occasion. It is available to read online via this link.
