Zheng Weiming said, “Breeding is a promoting power by which creature manages to survive and develop, it is a kind of positive feedback.” “Autopoieses, autocatalysis, self- organization and so on are all positive feedback which is the reason to promote systems evolving ” (Zheng, 1998). But he did not explain whether the origin of life is the result of positive feedback, nor did he provide a definition of life.

The Hypercycle Theory by Manfred Eigen (Eigen, & Schuster, 1979) was a breakthrough of life science which has been regarded as a classical theory. But Eigen did not provide a definition of life. Nor did Eigen noticed that Hypercycle is not the sufficient condition of life origin. For example, a system with tricarboxylic acid cycle is perhaps not a life.

Hu Hao demonstrated the mechanism of self-organization, “Positive feedback like the triple molecule model (2X+Y=3X), make system create effect of cooperation on quality and amplification effect on quantity. Because of this kind of interaction chains in which reasons are also results, a fluctuation used to be in a limit scope is possible to be amplified to the whole extent during a short period, and become a new orderly structure. Interactions of this kind of positive feedback is the micro-mechanism of system evolution in subsystem level” (Hu, 2002). Hu Hao explained the most important mechanism of self- organization clearly, but he did not use this micro- mechanism to explain the origin of life.

The book of Erich Jantsch The Self-organizing Universe analyses deeply the effect of positive feedback. But as the same mistakes of I. Prigogine, instead of treating auto-catalysis or self-reproduction as the essence of self-organization, Jantsch regarded non-equilibrium and metabolism as the essence of self-organization, and regarded fluctuation and openness as the essence of realizing order (Jantsch, 1980, p.55). He did not regard self-reproduction as the sufficient condition of the origin of life (Jantsch, 1980, p.103). What is more, Jantsch had some wrong concepts in his book. For example, he criticized reductionism (Jantsch, 1980, p.3), and said, “Autopoietic system is characterized by a certain autonomy
