The rearing of the child must become a process of liberation by methods which shall not impose ready-made ideas, but which should aid the child's natural self-unfoldment. The purpose of such an education is not to force the child's adaptation to accepted concepts. but to give free play to his [and her] originality, initiative, and individuality. Only by freeing education from compulsion and restraint can we create the environment for the manifestation of the spontaneous interest and inner incentives on the part of the child. Only thus can we supply rational conditions favorable to the development of the child's natural tendencies and his latent emotional and mental faculties. Such methods of education, essentially aiding the child's imitative quality and ardor for knowledge, will develop a generation of healthy intellectual independence. It will produce men and women capable, in the words of Francisco Ferrer, “of evolving without stopping, of destroying and renewing their environment without cessation; of renewing themselves also; always ready to accept what is best, happy in the triumph of new ideas, aspiring to live multiple lives in one life.”",

And this leads to difficulties which must prove insurmountable for any kind of authoritarianism. The authoritarian will in general select those who obey, who believe, who respond to his influence. But in doing so, he is bound to select mediocrities. For he excludes those who revolt, who doubt, who dare to resist his influence. Never can an authority admit that the intellectually courageous, i.e. those who dare to defy his authority, may be the most valuable type. Of course, the authorities will always remain convinced of their ability to detect initiative. But what they mean by this is only a quick grasp of their intentions, and they will remain for ever incapable of seeing the difference.”",
