In the late 19th and early 20th centuries, Austrian Sigmund Freud, a physiologist and psychiatrist, laid the foundations of psychoanalysis as a therapeutic method with his studies and revolutionized the way modern man perceives concepts such as consciousness and sexuality.

Man has aggressive instincts that drive him towards violence and war. He breaks every moral barrier and engages, in a primal way, in destruction. And death? What is its relationship with death? How inaccessible is the unconscious to the idea of loss?

With "Current Observations on War and Death" (Zeitgemabes uber Krieg und Tod, 1915), the father of psychoanalysis, stunned by the horror of World War I that plagues the civilized world, dives into the darkest depths of the human soul.
