Deep meaning lies often in childish play.

The line suggests that play—especially the seemingly aimless play of children—can carry serious significance. What looks trivial may be a rehearsal of social roles, a testing of rules, a creative exploration of possibility, or an unguarded expression of feeling. Read in a Schillerian key, it also aligns with the idea that aesthetic “play” mediates between sense and reason: in play, freedom and form meet without coercion. The quote thus elevates play from mere pastime to a mode of discovery, implying that wisdom and insight may appear most clearly where we least expect them—within spontaneity, imagination, and the unselfconscious.
