The havoc wrought by war, which one compares with the havoc wrought by nature, is not an unavoidable fate before which man stands helpless. The natural forces that are the cause of war are human passions, which it lies in our power to change. What are culture and civilization if not the taming of blind forces within us as well as in nature?
At present, the most effective way of preventing war would be for statesmen to direct politics so as to support a sound nationalism. This leads to concordance between people of kindred race and languages, whereas the conquest and coercion of people of different race and language inevitably lead to new wars.
When the crying child is immediately isolated, and it is explained to him at the same time that whoever annoys others must not be with them, if this isolation is the absolute result and cannot be avoided, in the child's mind a basis is laid for the experience that one must be alone when one makes oneself unpleasant or disagreeable.
The present practice is to impress one's own discoveries, opinions and principles on the child by constantly directing his actions. The last thing to be realised by the educator is that he really has before him an entirely new soul, a real self whose first and chief right is to think over the things with which he comes in contact.
The art of natural education consists in ignoring the faults of children nine times out of ten, in avoiding immediate interference, which is usually a mistake, and devoting one's whole vigilance to the control of the environment in which the child is growing up, to watching the education which is allowed to go on by itself.
When psychical phenomena have been as much investigated as physical, love will also receive its cumatology - that is, its science of waves. We shall follow the curves of the emotions through the ages, their movement of rise and fall, the oppositions and side-influences by which they have been determined.
Christianity is sustained by the knowledge that the object of man's life on earth is his development as an eternal being. Therefore, none of his expressions of life can be an end in itself, but must serve a higher purpose than the earthly life and happiness of the individual - or even than that of the race.
The exact sciences, which would be considered a priori as little adapted to women, for example mathematics, astronomy and physics, are exactly those in which thus far they have most distinguished themselves. This contains a warning against too precipitate conclusions about the intellectual life of woman.
Lack of courage or means often deters the European woman from more independent business activity, and this in spite of increasing freedom to choose her occupation, in spite of brilliant examples of successful undertakings of women, in photography, hotel or boarding-house management, dress-making, etc.
