"If a child finds no stimuli for the activities which would contribute to his development, he is attracted simply to 'things' and desires to possess them."

"Adults have not understood children or adolescents and they are, as a consequence, in continual conflict with them. The remedy is not that adults should gain some new intellectual knowledge or achieve a higher standard of culture. No, they must find a different point of departure. The adult must find within himself the still unknown error that prevents him from seeing the child as he is."

"Let us picture to ourselves a clever and proficient workman, capable, not only of producing much and perfect work, but of giving advice in his workshop, because of his ability to control and direct the general activity of the environment in which he works. The man who is thus master of his environment will be able to smile before the anger of others, showing that great mastery of himself which comes from consciousness of his ability to do things. We should not, however, be in the least surprised to know that in his home this capable workman scolded his wife if the soup was not to his taste, or not ready at the appointed time. In his home, he is no longer the capable workman; the skilled workman here is the wife, who serves him and prepares his food for him. He is a serene and pleasant man where he is powerful through being efficient, but is domineering where he is served. Perhaps if he should learn how to prepare his soup he might become a perfect man! The man who, through his own efforts, is able to perform all the actions necessary for his comfort and development in life, conquers himself, and in doing so multiplies his abilities and perfects himself as an individual. We must make of the future generation, powerful men, and by that we mean men who are independent and free."

"The peril of servilism and dependence lies not only in that "useless consuming of life," which leads to helplessness, but in the development of individual traits which indicate all too plainly a regrettable perversion and degeneration of the normal man. I refer to the domineering and tyrannical behaviour with examples of which we are all only too familiar. The domineering habit develops side by side with helplessness. It is the outward sign of the state of feeling of him who conquers through the work of others. Thus it often happens that the master is a tyrant toward his servant. It is the spirit of the task-master toward the slave."

"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 scientist is not the clever manipulator of instruments, he is the worshipper of nature and he bears the external symbols of his passion as does the follower of some religious order. To this body of real scientists belong those who, forgetting, like the Trappists of the Middle Ages, the world about them, live only in the laboratory, careless often in matters of food and dress because they no longer think of themselves; those who, through years of unwearied use of the microscope, become blind; those who in their scientific ardour inoculate themselves with tuberculosis germs; those who handle the excrement of cholera patients in their eagerness to learn the vehicle through which the diseases are transmitted; and those who, knowing that a certain chemical preparation may be an explosive, still persist in testing their theories at the risk of their lives. This is the spirit of the men of science, to whom nature freely reveals her secrets, crowning their labours with the glory of discovery. There exists, then, the "spirit" of the scientist, a thing far above his mere "mechanical skill," and the scientist is at the height of his achievement when the spirit has triumphed over the mechanism. When he has reached this point, science will receive from him not only new revelations of nature, but philosophic syntheses of pure thought."

"To prepare teachers in the method of the experimental sciences is not an easy matter. When we shall have instructed them in anthropometry and psychometry in the most minute manner possible, we shall have only created machines, whose usefulness will be most doubtful. Indeed, if it is after this fashion that we are to initiate our teachers into experiment, we shall remain forever in the field of theory. The teachers of the old school, prepared according to the principles of metaphysical philosophy, understood the ideas of certain men regarded as authorities, and moved the muscles of speech in talking of them, and the muscles of the eye in reading their theories. Our scientific teachers, instead, are familiar with certain instruments and know how to move the muscles of the hand and arm in order to use these instruments; besides this, they have an intellectual preparation which consists of a series of typical tests, which they have, in a barren and mechanical way, learned how to apply. The difference is not substantial, for profound differences cannot exist in exterior technique alone, but lie rather within the inner man. Not with all our initiation into scientific experiment have we prepared new masters, for, after all, we have left them standing without the door of real experimental science; we have not admitted them to the noblest and most profound phase of such study, — to that experience which makes real scientists."

"Freedom without organization of work would be useless. The child left free without means of work would go to waste, just as a new-born baby, if left free without nourishment, would die of starvation.The organization of the work, therefore, is the cornerstone of this new structure of goodness [in education], but even that organization would be in vain without the liberty to make use of it."

"The child is essentially alien to this society of men and might express his position in the words of the Gospel: My kingdom is not of this world"
