To realize that our knowledge is ignorance, This is a noble insight. To regard our ignorance as knowledge, This is mental sickness. Only when we are sick of the sickness Shall we cease to be sick. The Sage is not sick, being sick of sickness; This is the secret of health. -ch. 71, Tao Teh Ching, trans. John C. H. Wu, Shambhala, Boston & London, c.1990
