A child's character develops in accordance with the obstacles he has encountered... or the freedom favoring his development that he has enjoyed.

Imagination does not become great until human beings, given the courage and the strength, use it to create.

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

Education today, in this particular social period, is assuming truly unlimited importance. And the increased emphasis on its practical value can be summed up in one sentence: education is the best weapon for peace.

Discipline must come through liberty.

In nature nothing creates itself and nothing destroys itself.

The child has a mind able to absorb knowledge. He has the power to teach himself.
