Fearing and Fighting
Both in the brain and body, these amines produce rather general effects. These are not the programs that tell the animal or person exactly what to do, only that he should be aroused and ready. 6. Aggression (Violence) — not a Biological Necessity
As stated in the beginning, an aggressive response is ready to be used in every normal adult human by virtue of his possessing primordial unlearned instincts. But anger does not spring up spontaneously; at least in normal people, it has to be 'aroused'. It is triggered (and grows), for instance, by infringement of 'rights' to territory or possessions, frustration and attack on children etc. These responses are part of the mechanisms of 'fight' or flight' and come from the ancient core brain (including the hypothalamus) as much as from adrenal.
The question is - Do people have a biological need for the "discharge' of aggression (like orgasm in sex)? There is some evidence which lends plausibility to the theory that they do. For instance, readiness with which people respond to calls for aggressive war, universal prevalence of sports with contents of combat and violence (e.g. bull-fight), popularity of art and theatre in war, from sagas (like Mahābhārata) to borror films.
Nevertheless, it is incorrect to say that every individual feels that he has a need for aggression, though most do become angry when provoked. The tendency to defend one's rights or one's children does not mean that one has to be violent and it should not be equated with aggression.
Thus, aggression is neither a biological necessity nor it is universal. There are many historical instances of non-violent communities where violence was controlled voluntarily without any special laws or police.' There is no dearth of instances of non-violent response even to the most aggressive provocations in the history of mankind. 7. Militarism and Warfare
