When children come into contact with nature, they reveal their strength.

Watching a child makes it obvious that the development of his mind comes through his movements.

In nature nothing creates itself and nothing destroys itself.

Mental development must be connected with movement and be dependent on it. It is vital that educational theory and practice should be informed by that idea.

It is not enough for the teacher to love the child. She must first love and understand the universe. She must prepare herself, and truly work at it.

First the education of the senses, then the education of the intellect.

The child has other powers than ours, and the creation he achieves is no small one; it is everything.
