The most central, the most crucial part of the education of man’s genius is _the knowledge, the recognition of evil_ in all its protean forms and innumerable disguises, intellectual, æsthetic and moral, such as fallacies, sophisms, ugliness, deformity, prejudice, superstition, vice and depravity. Do not be afraid to discuss these matters with the child. For the knowledge, the recognition of evil does not only possess the virtue of immunization of the child’s mind against all evil, but furnishes the main power for habit-disintegration with consequent release and control of potential reserve energy, of manifestations of human genius. When a man becomes contented and ceases to notice the evils of life, as is done by some modern religious sects, he loses his hold on the powers of man’s genius, he loses touch with the throbbing pulse of humanity, he loses hold on reality and falls into subhuman groups. The purpose of education, of a _liberal_ education, is not to live in a fool’s paradise, or to go through the world in a post-hypnotic state of negative hallucinations. The true aim of a liberal education is, as the Scriptures put it, to have the _eyes opened_,—to be free from all delusions, illusions, from the _fata morgana_ of life. We prize a liberal education, because it _liberates_ us from subjection to superstitious fears, delivers us from the narrow bonds of prejudice, from the exalted or depressing delusions of moral paresis, intellectual dementia-praecox, and religious paranoia. A liberal education liberates us from the enslavement to the degrading influence of _all_ idol-worship. In the education of man do not play on his subconscious sense by deluding him by means of hypnotic and post-hypnotic suggestions of positive and negative hallucinations, with misty and mystic, beatific visions. Open his _eyes_ to undisguised reality. Teach him, show him how to strip the real from its unessential wrappings and adornments and see things in their nakedness. _Open the eyes of your children so that they shall see, understand and face courageously the evils of life._ Then will you do your duty as parents, then will you give your children the proper education.
