Note 5 — THE SYSTEM OF PLAY
Elizabeth L. Baldwin translation
He speaks (Psychology des Sentiments, Paris, 1896, p. 195) of an instinctive impulse “à depenser un superflu d’activité.” If, as I believe, this does not mean actual superfluity (Spencer’s “surplus” energy), then it must refer to our natural impulse to seek action and experience. See also Paolo Lombroso, Piacere di esplicare la propria activita. (Saggi di Psicologia del Bambino, Turin, 1894, p. 117.)
