Intellectual progress and increasing population levels have not contributed to the cause of peace as much as they have to disunion and violence. Nevertheless, let us not lose heart.
Man is a social animal too.
So we must plan at both ends of the spectrum. In fact, legal systems which aim at maintaining peace and eliminating violence deal only with non-respect of social norms and public opinion. But the law does not do anything to strengthen the self-restraint of those who do respect public opinion. We must concentrate on this section of society more than the other. We must keep in mind that conflicts of interest of various human beings would nevertheless continue to exist and yet we will have to train minds not to allow this temptation of personal motives to overcome the characteristic restraint.
