Antonio Salgado López (Ansaló) is the author of the following books: "Hórreos Ajenos" (2007), "Un legado singular" (2009), "Allá y siempre" (2014) and "Thaddeus" (2017). In this, his fifth book, Ansaló presents an Essay on two of the strongest and most overwhelming feelings that have invaded humans since they appeared on the face of the Earth. It will focus on the different ways of relating that these two powerful feelings have, what happens with each of these relationships, what lessons it leaves us and, above all, what we can expect for the century that has just begun. The thesis to be demonstrated is: “The traces that we leave, whether insignificant or important, will go on to integrate the traces of power and love of humanity for our descendants. The greater our understanding of them, the more effective our actions can be in managing the new relationships that the 21st century will impose on us ”. For the demonstration of the Thesis, twenty-four stories are narrated throughout the centuries, where the behaviors of its main characters are analyzed. A Relationship Matrix is used to group powerful or loving behaviors, depending on the prevalence of one over the other.
