[Summary]
　This study describes the chaotic effect in “A Madman’s Diary” to create a synergic metaphor called “Luxun and Chaos.” First, I analyze a general metaphor in cognitive linguistics. A synergic metaphor is the broader concept. When Luxun wrote “A Madman’s Diary,” China was engaged in two wars, civil and foreign. Therefore, many people behaved in disorderly and random manners.
　The protagonist of “A Madman’s Diary,” Madman, repeated the social criticism that a healthy person never speaks because he became paranoid. The input that the Madman’s neuronal cells receive would differ somewhat from that of a healthy person. If a cannibal would be born, after some generations, a small difference in the initial value could cause the indeterminism that creates an entirely different outcome phenomenon.
　The chaotic effect results from non-linearity and indeterminism in any academic discipline. To support these two points, I describe Luxun’s brain activity in writing his novels. If I could check Luxun’s intentions against artificial intelligence, there would be the objectivity.
