There is a lot of violence in the environment we live in. The aggressive behaviour is the cause of this violence. Is violent behaviour a part of an animal's actual nature?
Different philosophers and psychologists have different perspectives on why people act aggressively.
Thomas Hobbes, a philosopher, believed that because people are inherently violent and bad, only society has the power to control their behaviour.
In contrast, philosopher Jean-Jacques Rousseau held that people are naturally quite mild and that society instills aggressive behaviour in them.
