„To say that a great genius is half-mad, while recognizing his artistic prowess, is worth as much as saying that he was rheumatic, or that he suffered from diabetes. Madness, in fact, is a medical expression to which a balanced critic should pay no more heed than he would to the accusation of heresy brought by the theologian, or to the accusation of immorality brought by the public prosecutor.“

— James Joyce
