It was characteristic of current distinctions, mutual blending of study of men and theory of population, and association to political ideals of many thinkers. Based on the realistic demand, the classical theory of population contributed a valuable spirit of exploring the true nature of the humanity, a right control of the inner relation between things, and the dialectical relation of many thinkers in particular, which prove to be significantly important to our effort to develop a scientific theory of population and specifically solve China’s problem in population.
