If the idea of the universe is presented to the child in the right way, it will do more for him than just arouse his interest, for it will create in him admiration and wonder, a feeling loftier than any interest and more satisfying.

Within the child lies the fate of the future. Whoever wishes to confer some benefit on society must preserve him from deviations and observe his natural ways of acting. A child is mysterious and powerful and contains within himself the secret of human nature.

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.

Respect all the reasonable forms of activity in which the child engages and try to understand them.

The adult ought never to mold the child after himself, but should leave him alone and work always from the deepest comprehension of the child himself.

Joy is the evidence of inner growth.

Two things are necessary, the development of individuality and the participation of the individual in a truly social life.
