The great constructive ...

The great constructive energies of the child ... have hitherto been concealed beneath an accumulation of ideas concerning motherhood. We used to say it was the mother who formed the child; for it is she who teaches him to walk, talk, and so on. But none of this is really done by the mother. It is an achievement of the child. What the mother brings forth is the baby, but it is the baby who produces the man. Should the mother die, the baby still grows up and completes his work of making the man.

Quotes from the same author

Everyone in the world ought to do the things for which he is specially adapted. It is the part of wisdom to recognize what each one of us is best fitted for, and it is the part of education to perfect and utilize such predispositions. Because education can direct and aid nature but can never transform her.
At birth, the child leaves a person - his mother's womb - and this makes him independent of her bodily functions. The baby is next endowed with an urge, or need, to face the out world and to absorb it. We might say that he is born with 'the psychology of world conquest.' By absorbing what he finds about him, he forms his own personality.
This is education, understood as a help to life; an education from birth, which feeds a peaceful revolution and unites all in a common aim, attracting them as to a single centre. Mothers, fathers, politicians: all must combine in their respect and help for this delicate work of formation, which the little child carries on in the depth of a profound psychological mystery, under the tutelage of an inner guide. This is the bright new hope for mankind.
To give a child liberty is not to abandon him to himself.
A humankind abandoned in its earlier formative stage becomes its own greatest threat to survival.
