Locke attacks both the view that we have any innate principles (for example, the whole is greater than the part, do unto others as you would have done unto you, etc.) as well as the view that there are any innate singular ideas (for example, God, identity, substance, and so forth). The main thrust of Locke’s argument lies in pointing out that none of the mental content alleged to be innate is universally shared by all humans. He notes that children and the mentally disabled, for example, do not have in their minds an allegedly innate complex thought like “equals taken from equals leave equals”. He also uses evidence from travel literature to point out that many non-Europeans deny what were taken to be innate moral maxims and that some groups even lack the idea of a God. Locke takes the fact that not all humans have these ideas as evidence that they were not implanted by God in humans minds, and that they are therefore acquired rather than innate.
Man is a 'social animal'. Hence, showing an aggressive behaviour is equivalent to showing an animal behaviour. Psychologists say that though violent behaviour is inherent but can be managed. Providing a healthy and cordial home environment to kids helps them to build strong family values and reduces the tendency to react violently. Similarly, avoiding over consumption of alcohol and other such substances check this behaviour. Rehabilitation homes and support programs are available for those who need professional help. Meditation and practicing yoga also helps to rectify this negative approach towards self and others.
