The opposite extreme is the factitious and superficial motivation of fear, prizes, examinations, artificial and immediate rewards and penalties, which can only tattoo the mind and body with conventional patterns pricked in, but which lead an unreal life in the soul because they have no depth of soil in nature or heredity. However precious and coherent in themselves, all subject-matters thus organized are mere lugs, crimps, and frills. All such culture is spurious, unreal, and parasitic. It may make a scholastic or sophistic mind, but a worm is at the root and, with a dim sense of the vanity of all knowledge that does not become a rule of life, some form of pessimism is sure to supervene in every serious soul. With age a civilization accumulates such impedimenta, traditional flotsam and jetsam, and race fatigue proceeds with equal step with its increasing volume. Immediate utilities are better, but yet not so much better than acquisitions that have no other than a school or examination value. If, as Ruskin says, all true work is praise, all true play is love and prayer. Instil into a boy's soul learning which he sees and feels not to have the highest worth and which can not become a part of his active life and increase it, and his freshness, spontaneity, and the fountains of play slowly run dry in him, and his youth fades to early desiccation. The instincts, feelings, intuitions, the work of which is always play, are superseded by method, grind, and education by instruction which is only an effort to repair the defects of heredity, for which, at its best, it is vulgar, pinchbeck substitute. The best play is true genius, which always comes thus into the world, and has this way of doing its work, and all the contents of the memory pouches is luggage to be carried rather than the vital strength that carries burdens. Grosswell says that children are young because they play, and not _vice versa_; and he might have added, men grow old because they stop playing, and not conversely, for play is, at bottom, growth, and at the top of the intellectual scale it is the eternal type of research from sheer love of truth. Home, school, church, state, civilization, are measured in one supreme scale of values, viz., whether and how, for they aid in bringing youth to its fullest maturity. Even vice, crime, and decline are often only arrest or backsliding or reversion. National and racial decline beginning in eliminating one by one the last and highest styles of development of body and mind, mental stimulus of excessive dosage lowers general nutrition. A psychologist that turns his back on mere subtleties and goes to work in a life of service has here a great opportunity, and should not forget, as Horace Mann said, "that for all that grows, one former is worth one hundred reformers."
