Aggression, or The So-Called Evil

Konrad Lorenz – a prominent zoologist and zoopsychologist, philosopher, Nobel Prize winner in Physiology and Medicine, author of timeless works such as "Year of the Gray Goose," "The Ring of King Solomon," and "Man Finds a Friend."
 
"Aggression, or The So-Called... Evil" – is one of his most famous works, in which he examines aggression through a variety of biological species – aquarium fish, rats, geese, wolves, and finally, humans, and arrives at the paradoxical conclusion: deep personal attachment arises only in communities where a high level of aggression is observed. Where there is no aggression, there is no strong friendship and true love. So can we consider aggression evil, and the suppression of aggression a good? And will humanity be able to develop in the case of a complete renunciation of aggression towards its own kind?..
