Crime is cryptogamous and flourishes in concealment, so that not only does falsehood facilitate it, but certain types of lies often cause and are caused by it. The beginning of wisdom in treatment is to discriminate between good and bad lies. My own study[10] of the lies of 300 normal children, by a method carefully devised in order to avoid all indelicacy to the childish consciousness, suggested the following distinct species of lies. It is often a well-marked epoch when the young child first learns that it can imagine and state things that have no objective counterpart in its life, and there is often a weird intoxication when some absurd and monstrous statement is made, while the first sensation of a deliberate break with truth causes a real excitement which is often the birth pang of the imagination. More commonly this is seen in childish play, which owes a part of its charm to self-deception. Children make believe they are animals, doctors, ogres, play school, that they are dead, mimic all they see and hear. Idealising temperaments sometimes prompt children of three or four suddenly to assert that they saw a pig with five ears, apples on a cherry tree, and other Munchausen wonders, which really means merely that they have had a new mental combination independently of experience. Sometimes their fancy is almost visualisation and develops into a kind of mythopeic faculty which spins clever yarns and suggests in a sense, quite as pregnant as Froschmer asserts of all mental activity and of the universe itself, that all their life is imagination. Its control and not its elimination in a Gradgrind age of crass facts is what should be sought in the interests of the highest truthfulness and of the evolution of thought as something above reality, which prepares the way for imaginative literature. The life of Hartley Coleridge,[11] by his brother, is one of many illustrations. He fancied cataract of what he named "jug-force" would burst out in a certain field and flow between populous banks, where an ideal government, long wars, and even a reform in spelling, would prevail, illustrated in a journal devoted to the affairs of this realm--all these developed in his imagination, where they existed with great reality for years. The vividness of this fancy resembles the pseudo-hallucinations of Kandinsky. Two sisters used to say, "Let us play we are sisters," as if this made the relation more real. Cagliostro found adolescent boys particularly apt for training for his exhibition of phrenological impostures, illustrating his thirty-five faculties. "He lied when he confessed he had lied," said a young Sancho Panza, who had believed the wild tales of another boy who later admitted their falsity. Sir James Mackintosh, near puberty, after reading Roman history, used to fancy himself the Emperor of Constantinople, and carried on the administration of the realm for hours at a time. His fancies never quite became convictions, but
