There is in the child a special kind of sensitivity which leads him to absorb everything about him, and it is this work of observing and absorbing that alone enables him to adapt himself to life

There is in every child a painstaking teacher so skillful that he obtains identical results in all children in all parts of the world. The only language men ever speak perfectly is the one they learn in babyhood, when no one teaches them anything.

Growth and psychic development are therefore guided by: the absorbent mind, the nebulae and the sensitive periods, with their respective mechanisms. It is these that are hereditary and characteristic of the human species. But the promise they hold can only be fulfilled through the experience of free activity conducted in the environment.

What the hand does the mind remembers.

The greatness of the human personality begins at the hour of birth.

The children are now working as if I did not exist.

The principal agent is the object itself and not the instruction given by the teacher. It is the child who uses the objects; it is the child who is active, and not the teacher.
