Works of art can fail so easily, it is so difficult for them to succeed. One man will fall silent because of his lack of feeling; another, because his emotion chokes him. A third frees himself, not from the burden that weighs on him, but only from a feeling of unfreedom. A forth breaks his tools because they have too long been used to exploit him. The world is not obliged to be sentimental. Defeats should be acknowledged; but one should not conclude from them that there should be no more struggles.
