We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child's life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.

The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will laterserve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.

It can be fairly argued that the highest priority for mankind is to save itself from extinction. However, it can also be argued th at a society that neglects its children and robs them of their human potential can extinguish itself without an external enemy.

The parent who loves his child dearly but asks for nothing in return might qualify as a saint, but he will not qualify as a parent. For a child who can claim love without meeting any of the obligations of love will be a self-centered child and many such children have grown up in our time to become petulant lovers and sullen marriage partners because the promise of unconditional love has not been fulfilled.

We find that the child who does not yet have language at his command, the child under two and a half, will be able to cooperate with our education if we go easy on the "blocking" techniques, the outright prohibitions, the "no's" and go heavy on "substitution" techniques, that is, the redirection or certain impulses and the offering of substitute satisfactions.

An older child, one who possesses a conscience, will be troubled with self-reproaches and feelings of shame for his naughtiness, even if he is not discovered. But our two-year-olds and our three-year- olds experience guilt feelings only when they feel or anticipate disapproval from the outside. In doing this, they have taken the first steps toward the goal of conscience, but there is a long way ahead before the policeman outside becomes the policeman inside.

If we can find a principle to guide us in the handling of the child between nine and eighteen months, we can see that we need to allow enough opportunity for handling and investigation of objects to further intellectual development and just enough restriction required for family harmony and for the safety of the child.
