They don’t see the present moment (x(t)), only how fast it’s changing. ‘Things are getting better,’ they say, even when the present is terrible. Or, ‘It’s all falling apart,’ when the present is stable. The derivative system is anxious. It never rests.” Professor Deniz called her after class. He held up her paper.
