These three essays by Hans Magnus Enzensberger, written between 1992 and 2006 and accompanied by a coda in the form of a parable written in 2015, offer us a clarifying perspective on our time from the account of the complex German experience with migrations and xenophobia; The realization that the hopes placed on the "dividends of peace" at the end of the Cold War were vain; The analysis of the characteristics of a new megalomaniac, vengeful and death-loving terrorism, and a review of the brutal civil wars that have ravaged contemporary history. Why update some already published texts and put them together in one volume? The reason is quite simple: the conflicts they deal with have become so marked over the last twenty-five years that any attempt to minimize or deny them has proved irresponsible. It is necessary to continue talking about these issues. With optimism, but without denying the evidence. Hans Magnus Enzensberger opened the Arguments collection with Details. Forty-seven years later, we reached number 500 with this exemplary essay, unavoidable, by the same author; Four brilliant texts from the point of view of analysis and prognosis by one of the indispensable thinkers of our time.

Few intellectuals have remained so loyal to this idea of ​​"commitment" (Mario Vargas Llosa, Letras Libres).
