The greatest sign of success for a teacher...is to be able to say, "The children are now working as if I did not exist."

The more the capacity to concentrate is developed, the more often the profound tranquility in work is achieved, then the clearer will be the manifestation of discipline within the child.

Bring the child to the consciousness of his own dignity, and he will be free. We see no limit to what should be offered to the child, for his will be an immense field of chosen activity.

We especially need imagination in science. It is not all mathematics, nor all logic, but it is somewhat beauty and poetry.

If help and salvation are to come they can only come from the children, for the children are the makers of men.

To teach details is to bring confusion; to establish the relationship between things is to bring knowledge.

Within the child lies the fate of the future.
