What is necessary to keep providing good care to nature has completely fallen into ignorance during the materialism era.

You can get an idea of human nature only when you can see the relationship of the individual human being to the whole cosmos.

Knowledge has value only insofar as it contributes to the all-round development of the whole nature of man.

One can ascend to a higher development only by bringing rhythm and repetition into one's life. Rhythm holds sway in all nature.

Learning certain things purely through memory is related to the developmental forces that are present between the sixth or seventh year and the fourteenth year of life. This quality of human nature is what mathematical instruction should be based on.

All of nature begins to whisper its secrets to us through its sounds. Sounds that were previously incomprehensible to our soul now become the meaningful language of nature.
