These differences then become the source of potential constructions. Teacher-training systems are likely to be profoundly modified by this. Piaget shows us how the child's selfishness represents one of the major obstacles in understanding the activities of sharing and interdependence. As a result, it is necessary to develop education for otherness by teaching children to place themselves in a negotiating process where diversity is valued and encouraged. We should learn to teach the confrontation of opposites.
Nothing is more fruitful than a difficulty overcome.
