Popper found the independence of knowledge expressed in words, which is different from other substances and  consciousness, and deserves special status. The meaning of Popper's “objective content of ideas” is not accurate. If it refers to the system of word and symbols, then some of his theory made sense.

Popper believes that the development of knowledge is very similar to the evolution of animals and plants. ^[2] We should understand that the objective content of the idea (the order of symbols in the textual which is constantly innovating) is essentially the product of the process of material getting complex and orderly after human beings originated, that is, part of the general evolutionary product.  Although Popper did not use the term “general evolution”, nor did he make it clear, he actually pointed out that the development of knowledge was general evolution and pointed out the specific way of general evolution. That is P1-TT-EE-P2, in which P1 and P2 represent problems, TT (the tentative theory) is the imaginative conjectural solution which we first reach, and EE (error-elimination) is consists of a severe critical examination of our conjecture.^[3]

The genetic material of an organism is first tran- scribed into messenger RNA, and then translated into the structure of protein, which forms tissues, organs, and creatures. In the process of human learning, cultural genes, ie. concepts and theories as written symbols, must also be transcribed to consciousness in the human mind, and then translated to production, that is, under the control of consciousness, to establish social organizations and change the world. Although Popper did not use the term “cultural gene”, he pointed out the cultural functions of the third world: if the “library and our ability to learn from it still existed, our world would run again after heavy losses.” If “all libraries are destroyed ... there will be no re-emergency of our civilization
