Yin Haiguang’s investigation and pursuit of the idea of “Man” reflect not merely a limited historical or parochial academic interest, but indeed address an ultimate concern of humanity which transcends any spatio-temporal limitations. In criticizing “modern man” for its faceless and non-self-identical figure, Yin Haiguang brings the conditions, purposes and noble values of humanity to light. His work has extraordinary significance for the highest aims of humanity and civilization.
