Play is the work of the child.

An education capable of saving humanity is no small undertaking; it involves the spiritual development of man, the enhancement of his value as an individual, and the preparation of young people to understand the times in which they live.

The objects in our system are instead a help to the child himself, he chooses what he wants for his own use, and works with it according to his own needs, tendencies and special interests. In this way, the objects become a means of growth.

Let us treat them [children], therefore, with all the kindness which we would wish to help to develop in them.

The child’s parents are not his makers but his guardians.

Culture and education have no bounds or limits; now man is in a phase in which he must decide for himself how far he can proceed in the culture that belongs to the whole of humanity.

The ancient saying, "There is nothing in the intellect which was not first in some way in the senses," and senses being explorers of the world, opens the way to knowledge.
