"Even after centuries of human interacting, children still co..." — Leo Buscaglia quote meaning

Even after centuries of human interacting, children still continue to rebel against their parents and siblings. Young marrieds look upon their in-laws and parents as obstacles to their independence and growth. Parents view their children as selfish ingrates. Husbands desert their wives and seek greener fields elsewhere. Wives form relationships with heroes of soap operas who vicariously bring excitement and romance into their empty lives. Workers often hate their bosses and co-workers and spend miserable hours with them, day after day. On a larger scale, management cannot relate with labour. Each accuses the other of unreasonable self-interests and narrow-mindedness. Religious groups often become entrapped, each in a provincial dogma resulting in hate and vindictiveness in the name of God. Nations battle blindly, under the shadow of the world annihilation, for the realization of their personal rights. Members of these groups blame rival groups for their continual sense of frustration, impotence, lack of progress and communication. We have obviously not learned much over the years. We have not paused long enough to consider the simple truth that we humans are not born with particular attitudinal sets regarding other persons, we are taught into them. We are the future generation's teachers. We are, therefore, the perpetrators of the confusion and alienation we abhor and which keeps us impotent in finding new alternatives. It is up to us to diligently discover new solutions and learn new patterns of relating, ways more conducive to growth, peace, hope and loving coexistence. Anything that is learned can be unlearned and relearned. In this process called change lies our real hope.
