From time in memorial, there has always been conflict. As the world developed so did the scale of these conflicts. This hunger for violence and aggression has been questioned by many psychologists and as a result led to one of the more important questions of nature versus nurture. On the one hand some have argued that aggression is innate and on the other hand, it has been argued that aggression is a learned behavior and that our social environment influences us to be aggressive. In trying to answer the question of whether humans are innately aggressive this essay will look at theories that favor the nature argument and include ethology, evolutionary social psychology, psychodynamic theory and Freud’s theory of aggression. This paper will also evaluate the theories that support the idea of aggression being a learned phenomenon. That is the social learning theory.

However, all theories of aggression do have one thing in common in that there is some form of injury as a result of aggression. One of the forerunners of aggression being an instinct was Sigmund Freud.
Freud argued that Thanatos, the death instinct that we are born with was
