Concentration is the key that opens up to the child the latent treasures within him.

It is not in human nature for all men to tread the same path of development, as animals do of a single species.

The environment itself will teach the child, if every error he makes is manifest to him, without the intervention of a parent of teacher, who should remain a quiet observer of all that happens.

We teachers can only help the work going on, as servants wait upon a master.

The secret of good teaching is to regard the child's intelligence as a fertile field in which seeds may be sown, to grow under the heat of flaming imagination.

If we really want children to grow into independent and resourceful adults, we should stop pouring their milk as soon as they have learned to pour it themselves and stop fastening their buttons as soon as they can fasten them without help.

Only practical work and experience lead the young to maturity.
