We must, in our lessons, see to it that the children experience the beautiful, artistic, and aesthetic conception of the world; and their ideas and mental pictures should be permeated by a religious/moral feeling. Such feelings, when they are cultivated throughout the elementary school years, will make all the difference during the thirteenth, fourteenth, and fifteenth years. For a child whose feelings for the beautiful, for the aesthetic conception of the world, have not been stimulated will during puberty easily become overly sensual, even perhaps erotic.
There is no better way of counteracting the erotic feelings than through the healthy development of the aesthetic sense for the sublime and beautiful in nature. If you succeed in making the children feel deeply the beauty, the colors, in sunrise and sunset, in the flowers, experience the sublime splendor of a thunderstorm— if, as it were, you cultivate in them the aesthetic sense —you will do more for them than is done by the often absurdly practiced sex education given to children at an ever younger age. It is the feeling for the beautiful, an aesthetic confrontation with the world, that counteracts the erotic feeling. By experiencing the world as beautiful, the human being will also attain the right, healthy relation to his or her body, will not be tormented by it, as happens in eroticism.
It is most important during puberty that the children have developed certain moral, religious feelings. Such feelings also strengthen the astral body and ego. They become weak if the religious, moral feelings and impulses have been neglected.
The children then turn indolent, as though physically paralyzed. This will show itself especially during the years we are now discussing. The lack of moral and ethical impulses also leads to irregularities in the sexual life.
We must consider the differences between girls and boys in our education leading up to this age. We must make the effort to develop the girls’ moral and ethical feelings in a way that they are directed toward the aesthetic life. We must take special care that the girls especially enjoy the moral, the religious, and the good in what they hear in the lessons. They should take pleasure in the knowledge that the world is permeated by the supersensible; they should be given pictures that are rich in imagination, that express the world as permeated by the divine, that show the beautiful aspects of the good and moral human being.
In regard to boys, it will be necessary to provide them with ideas and mental pictures that tend toward strength and affect the religious and ethical life. With girls, we should bring the religious and moral life to their very eyes, while with boys we should bring the religious and beautiful predominantly into the heart, the mind, stressing the feeling of strength that radiates from them.
Naturally, we must not take these things to an extreme, should not think of making the girls into aesthetic kittens that regard everything merely aesthetically. Nor should the boys be made into mere louts, as would be the inevitable result of their egotisms being engendered through an unduly strong feeling of their strength — which we ought to awaken, but only by connecting it to the good, the beautiful, and the religious.
We must prevent the girls from becoming superficial, from becoming unhealthy, sentimental connoisseurs of beauty during their teenage years. And we must prevent the boys from turning into hooligans. These dangers do exist.
