Music as advocate – ‘I am thirsting for a master composer’, said an innovator to his disciple, ‘who can learn my thoughts from me and hereafter speak them in his language: that way I will better penetrate into people’s ears and hearts. With tones one can seduce people into every error and every truth: who could refute a tone?’ – ‘So you would like to be considered irrefutable?’ said his disciple. The innovator replied: ‘I wish for the sprout to become a tree. For a teaching to become a tree, it has to be believed for a good while; for it to be believed, it has to be considered irrefutable. The tree needs storms, doubts, worms, and malice in order to reveal the nature and strength of its sprout; may it break if it is not strong enough! But a sprout can only be destroyed – not refuted!’ When he had said that, his disciple cried impetuously: ‘But I believe in your cause and consider it so strong that I will say everything, everything that I still have on my mind against it’. The innovator laughed to himself and wagged a finger at him. ‘This kind of discipleship’, he said, ‘is the best, but it is dangerous and not every kind of teaching can withstand it’.
