Times have changed, and science has made great progress, and so has our work; but our principles have only been confirmed, and along with them our conviction that mankind can hope for a solution to its problems, among which the most urgent are those of peace and unity, only by turning its attention and energies to the discovery of the child and to the development of the great potentialities of the human personality in the course of its formation.

What is a scientist?... We give the name scientist to the type of man who has felt experiment to be a means guiding him to search out the deep truth of life, to lift a veil from its fascinating secrets, and who, in this pursuit, has felt arising within him a love for the mysteries of nature, so passionate as to annihilate the thought of himself.

The child is the spiritual builder of mankind, and obstacles to his free development are the stones in the wall by which the soul of man has become imprisoned.

The environment must be rich in motives which lend interest to activity and invite the child to conduct his own experiences.

The instructions of the teacher consist then merely in a hint, a touch-enough to give a start to the child. The rest develops of itself.

Within the child lies the fate of the future.

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.
