Joy, feeling one’s own value, being appreciated and loved by others, feeling useful and capable of production are all factors of enormous value for the human soul.

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

To assist a child we must provide him with an environment which will enable him to develop freely.

It is almost possible to say that there is a mathematical relationship between the beauty of his surroundings and the activity of the child; he will make discoveries rather more voluntarily in a gracious setting than in an ugly one.

Only practical work and experience lead the young to maturity.

The laws governing the universe can be made interesting and wonderful to the child, more interesting even that things in themselves, and he begins to ask: What am I? What is the task of man in this wonderful universe? Do we merely live here for ourselves, or is there something more for us to do? Why do we struggle and fight? What is good and evil? Where will it all end?
