But this laughter is the reason why the Tuscans invented science and the clear Tuscan drawing in their cool paintings; laughter means distance. Conversely: where laughter is absent, madness begins. Every time I’ve had a chance to observe an outbreak of psychosis or a first-rate clinical anxiety neurosis the signal has been given in the absence of humour – one is potentially insane. The whole art of learning to live means holding fast to laughter; without laughter the world is a torture chamber, a dark place where dark things will happen to us, a horror show filled with bloody deeds of violence.
It is related of Leonardo da Vinci that he had a laughter which was so beautiful that those who had heard it could never again forget it.
Of Leonardo we know that he laughed this bubbling laughter of gold, which was the Florentine laughter in the deepest sense. Yet Leonardo was not a happy man, and his laughter had nothing to do with happiness.
Dante also has this laughter.
