In recent years, the study of vulnerabilities from culturally and educationally has become fashionable. Since the economically poor, the disabled, those suffering any kind of confinement, children in marginalized areas to ethnic and sexual minorities; to the reality of all, the relevant question is what is at risk or already broken or damaged? Trying to answer this question, necessarily involves daring to penetrate what is played on the psyche of our contemporary society. This book focuses particularly on the question of how, on the subject of the vulnerabilities of children is at stake and how the unconscious, from there, operate hegemonies. Such an effort requires combine into a single approach various contributions of both history and sociology and psychology, which is why the study of the phenomenon of harm to children, is here addressed in close discussion with the philosophy, rather than maintain a constant epistemological and methodological supervision of its assertions. From recover Lacanian principles, sociological theories on social structures and various field inquiries about the vulnerabilities in popular children in urban areas of Mexico City, this book is an effort to renew the discussion on a topic given its characteristics, run the constant risk of anquilosarse in analytical negligence, if not falling into a topic of common ground and making it politically harmless, and domesticable especially in its practical consequences at all levels of reality in which it can act.
