"I had known in my life the greatest artists and the most cultured and successful people, but none of them was happy, although some of them pretended to be. Behind the mask one could guess, without much clairvoyance, the same anguish and the same suffering. And the fact is that in this world there is perhaps no such thing as happiness. There are only happy moments." (Isadora Duncan)
"Había conocido en mi vida a los más grandes artistas y a la gente más culta y triunfadora, pero ninguno de ellos era feliz, aunque algunos lo simularan. Detrás de la máscara podía adivinarse, sin mucha clarividencia, la misma angustia y el mismo padecimiento. Y es que en este mundo no existe quizá la dicha. No hay sino momentos felices." (Isadora Duncan)
