The nursery school, therefore, appears as a counter influence against the almost hidden processes by which society through the parents undertakes the premature exploitation of children’s interests in behalf of its own conventionalized and not very natural program of life. It thus happens that one of the first considerations in a nursery school program is that after satisfying the expectations of the family with regard to the physical care of children it should keep its further thinking in firm alignment with biological rather than social understandings with regard to the present and future welfare of the child, and this no matter what new problem it sets for parents, and no matter what amount of diversity of opinion may arise between them and the school.
