Pleasure in nonsense. – How can man take pleasure in nonsense? For wherever in the world there is laughter this is the case; one can say, indeed, that almost everywhere there is happiness there is pleasure in nonsense. The overturning of experience into its opposite, of the purposive into the purposeless, of the necessary into the arbitrary, but in such a way that this event causes no harm and is imagined as occasioned by high spirits, delights us, for it momentarily liberates us from the constraint of the necessary, the purposive and that which corresponds to our experience, which we usually see as our inexorable masters; we play and laugh when the expected (which usually makes us fearful and tense) discharges itself harmlessly. It is the pleasure of the slave at the Saturnalia.
