"Piety, then, needs a counterpoise, something to prevent it from being exercised in an excessively rigid way; and this it has, in most intellectual temperaments, in the quality I would call playfulness. We speak of the play of the mind; and certainly the intellectual relishes the play of the mind for its own sake, and finds in it one of the major values in life. What one thinks of here is the element of sheer delight in intellectual activity. Seen in this guise, intellect may be taken as the healthy animal spirits of the mind, which come into exercise when the surplus of mental energies is released from the tasks required for utility and mere survival. “Man is perfectly human,” said Schiller, “only when he plays.” And it is this awareness of an available surplus beyond the requirements of mere existence that his maxim conveys to us. Veblen spoke often of the intellectual faculty as “idle curiosity”—but this is a misnomer in so far as the curiosity of the playful mind is inordinately restless and active. This very restlessness and activity gives a distinctive cast to its view of truth and its discontent with dogmas."
