There is something overtly invasive about biographies that seem to suggest that the very interest in them is reprehensible. What is sought in them is the same intimacy that, in life, common sense commands to respect. But human curiosity is invincible, and biographies are indispensable. Although a work is independent of the biography, the author cannot detach himself from it. And it is they that show us the reality that supports the artistic act, a multifaceted reality, more or less grateful, more or less unusual, but which always motivates expression. They are also responsible for revealing a dimension that is often essential to the correct understanding of a work, and there is no doubt that, because of the much they have clarified and contributed, one ends up at peace with the guilt of that feeling of invasion.
