"In Self-help books what a rip off! Eparquio Delgado crumbling self-help as never before had I Norteado with the rigor and the brain that governs the collection of Laetoli 'What a scam!" [...]. Until now nobody had dissected synthesized and self-help as Eparquio Delgado, directly, clearly and succinctly, bringing order and bringing together nicely varied analysis of their predecessors "(Toni Hernandez, e-science).

"In line with the own cultural individualism called late capitalism he says the author, self-help books limit their psychological consequences problems, attributing the success or failure exclusively to the actions of the person and ignoring external causes or materials, which in many cases they can not be addressed without recourse to the other, political or group action. Any situation can be addressed by simplifying it as a problem related to personal development and awareness raising. All in a cultural context where economic success is interpreted as exclusively dependent on the attitude and self-esteem of the person, obviating the existence of inequality, and where free states that any disease, like breast cancer originates the mind".
