I have studied the child. I have taken what the child has given me and expressed it and that is what is called the Montessori method.

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.
