The child who concentrates is immensely happy.

One test of the correctness of educational procedure is the happiness of the child.

The child is not an empty being who owes whatever he knows to us who have filled him up with it. No, the child is the builder of man. There is no man existing who has not been formed by the child he once was.

Free the child's potential, and you will transform him into the world.

When you have solved the problem of controlling the attention of the child, you have solved the entire problem of its education.

At three years of age, the child has already laid the foundations of the human personality and needs the special help of education in the school. The acquisitions he has made are such that we can say the child who enters school at three is an old man.
