"I do not like seriousness. I think it is irreligious."

I do not like seriousness. I think it is irreligious. Or, if you prefer the phrase, it is the fashion of all false religions. The man who takes everything seriously is the man who makes an idol of everything: he bows down to wood and stone until his limbs are as rooted as the roots of the tree or his head as fallen as the stone sunken by the roadsite. It has often been discussed whether animals can laugh. The hyena is said to laugh, but it is rather in the sense in which the M.P. is said to utter "an ironical cheer." At the best, the hyena utters an ironical laugh. Broadly, it is true that all animals except Man are serious.
