Abstract: Marx's writing of Critique of Hegel's Philosophy is accompanied with the excerpting of Kreuznach Notebooks concentrating on political theory and history, which divide Critique into two different part—the latter half has surpassed the first half in theoretical level. In other words, due to Notebooks' historical investigation, the latter half of Critique has contained the embryonic form of "Tripartite-Social-Formation-Theory", which lays its emphasis on the significance of individual freedom and has not gained its complete development and clear expounding until Outline of Critique of Political Economy.
