The work of education is divided between the teacher and the environment.

Work is necessary; it can be nothing less than a passion; a person is happy in accomplishment.

The only language men ever speak perfectly is the one they learn in babyhood, when no one can teach them anything!

Let the children be free; encourage them; let them run outside when it is raining; let them remove their shoes when they find a puddle of water; and when the grass of the meadows is wet with dew, let them run on it and trample it with their bare feet; let them rest peacefully when a tree invites them to sleep beneath its shade; let them shout and laugh when the sun wakes them in the morning.

Do not erase the designs the child makes in the soft wax of his inner life.

Movement, or physical activity, is thus an essential factor in intellectual growth, which depends upon the impressions received from outside. Through movement we come in contact with external reality, and it is through these contacts that we eventually acquire even abstract ideas.

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?
