Abstract: Secret version of Philosophy of Right reveals Hegel’s radical character.Hegel’s concern on reason and reality and power of the monarch and other issues is not a reflection of his political conservative position,but the expression of his revolutionary sentiments.After understanding of the political economy,Marx quietly played down the criticism against Hegel’s conservation.However,under the influence of Hegel’s Philosophy of Right,Marx turned his attention to the field of economy.The praise of revolution in Philosophy of History and the affirmation of the superiority of the right to life in Philosophy of Right both latently contained the idea that historical progress was achieved by the revolution and rebellion was inevitable by the poor for their rights to life,which became a preview of Marx’s class theory.Marx inherited Hegel’s ideas about revolution and property rights,which ultimately developed into the political theory for the proletariat to seize political power and survival.

Key words: Hegel, Marx, revolution, property rights
