This work has had significant impact on the social and biological sciences and is now a classic point of reference for investigations of behavioral patterns. Lorenz presents his findings on the mechanism of aggression and how animals control destructive drives in the interest of the species.
Lorenz is well known for his extensive research on the roots of aggression. He had the opportunity to personally experience the effects of aggression when he was drafted into Hitler’s army. While there, he served as a psychologist in the Office of Racial Policy from 1942-1944 before being captured by the Soviet army and being held as a prisoner of war until 1948.
