Reading this book has evoked me to Foucault when he said that his work and his theories should be taken as a toolbox or as a lens, which are used if they allow a better view and leaving aside whether or disturb the look muddy work. I think the construction of the enemy in the Colombian armed conflict 1998-2010, is that: a good toolbox or good lenses that allow us auscultate some phenomena and raises some concerns?
