The more we try to improve our schools, the heavier the teaching task becomes; and the better our teaching methods the more difficult they are to apply.

Every time we teach a child something, we keep him from inventing it himself. On the other hand, that which we allow him to discover for himself will remain with him visible for the rest of his life.

How can we, with our adult minds, know what will be interesting? If you follow the child...you can find out something new.

This means that no single logic is strong enough to support the total construction of human knowledge.

Play is the work of childhood.

How much more precious is a little humanity than all the rules in the world.

Teaching means creating situations where structures can be discovered.
