§ XXVII. Secondly: The men who play necessarily. That highest species of playfulness, which we have just been considering, is evidently the condition of a mind, not only highly cultivated, but so habitually trained to intellectual labor that it can bring a considerable force of accurate thought into its moments even of recreation. This is not possible, unless so much repose of mind and heart are enjoyed, even at the periods of greatest exertion, that the rest required by the system is diffused over the whole life. To the majority of mankind, such a state is evidently unattainable. They must, perforce, pass a large part of their lives in employments both irksome and toilsome, demanding an expenditure of energy which exhausts the system, and yet consuming that energy upon subjects incapable of interesting the nobler faculties. When such employments are intermitted, those noble instincts, fancy, imagination, and curiosity, are all hungry for the food which the labor of the day has denied to them, while yet the weariness of the body, in a great degree, forbids their application to any serious subject. They therefore exert themselves without any determined purpose, and under no vigorous restraint, but gather, as best they may, such various nourishment, and put themselves to such fantastic exercise, as may soonest indemnify them for their past imprisonment, and prepare them to endure their recurrence. This sketching of the mental limbs as their fetters fall away,--this leaping and dancing of the heart and intellect, when they are restored to the fresh air of heaven, yet half paralyzed by their captivity, and unable to turn themselves to any earnest purpose,--I call necessary play. It is impossible to exaggerate its importance, whether in polity, or in art.
