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

As soon as children find something that interests them they lose their instability and learn to concentrate.

The most important period of life is not the age of university studies, but the first one, the period from birth to the age of six.

The aim of education should not be to teach how to use human energies to improve the environment, for we are finally beginning to realize that the cornerstone of education is the development of the human personality, and that in this regard education is of immediate importance for the salvation of mankind.

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.

All our handling of the child will bear fruit, not only at the moment, but in the adult they are destined to become.

He does it with his hands, by experience, first in play and then through work. The hands are the instruments of man's intelligence.
