Play is motor poetry. Too early distinction between play and work should not be taught. Education perhaps should really begin with directing childish sports aright. Froebel thought it the purest and most spiritual activity of childhood, the germinal leaves of all later life. Schooling that lacks recreation favors dulness, for play makes the mind alert and its joy helps all anabolic activities. Says Brinton, "the measure of value of work is the amount of play there is in it, and the measure of value of play is the amount of work there is in it." Johnson adds that "it is doubtful if a great man ever accomplished his life work without having reached a play interest in it." Sully[21] deplores the increase of "agolasts" or "non-laughers" in our times in merry old England[22] every one played games; and laughter, their natural accompaniment, abounded. Queen Elizabeth's maids of honor played tag with hilarity, but the spirit of play with full abandon seems taking its departure from our overworked, serious, and tons, age. To requote Stevenson with variation, as _laborari_, [To labor] so _ludere, et joculari orare sunt_. [To play and to jest are to pray] Laughter itself, as Kühne long ago showed, is one of the most precious forms of exercise, relieving the arteries of their tension.[23]
