This paper addresses some issues that I consider to be particularly important in order to better understand and possibly countervail the phenomenon of violence. It especially focuses on the following points: a) the concept of violence; b) the Seville Statement on Violence and the possibility of revisiting and updating it; c) emotional and cultural factors as causes of violence; d) a proposal of a new perspective on the study of the relations between ingroup and outgroup; e) the possible role of the awareness of the existence of death in the context of human violence; f) the necessity of including violence against animals in the study of human violence.
