Abstract:1923，An “ancient phonetic differentiation” broke out in the field of bet365 joining bonus code linguistics around the “scientific principles” of ancient phonetic research。After this debate，The “scientific”-oriented modern research paradigm has become the mainstream of bet365 joining bonus code linguistics research。At the same time, the "Ancient History Debate" and the "Scientific and Metaphysical Debate" also occurred。"Ancient Sound Analysis" and "Ancient History Analysis" have conquered the two "fortresses" of traditional bet365 joining bonus code academic "ancient sound" and "ancient history"，The “Scientific Debate” has enhanced bet365 joining bonus code scholars’ understanding of “science”。The three debates all advocated “seeking truth” by “bringing evidence” in terms of academic epistemology，The study of bet365 joining bonus code literature and history has thus entered modernization as a whole。bet365 joining bonus code Marxist scholars take a step forward，Point out that the destination of "seeking truth" is "seeking truth"，The theory that can answer "why" in the material world and the overall historical process is historical materialism。From now on，Research on modern bet365 joining bonus code literature and history is gradually unfolding from the two dimensions of "what" and "why"。
