Abstract: The outlook on future society in Marx’s early works is the primary form of scientific socialism. The outlook on future society expounded from a philosophical perspective is not “immature” or “unscientific”. The classic works of Marx in the middle and later periods also demonstrate the theory of future society from a philosophical perspective. In early works such as A Contribution to the Critique of Hegel’s Philosophy of Right Introduction and Economic & Philosophic Manuscripts of 1844, Marx used economics to demonstrate the historical mission of the proletariat, the class contradictions between the bourgeoisie and the proletariat, and the essence of exploitation in capitalist society. The theory of surplus value is not the only condition for the formation of scientific socialism. It is not advisable and unfair to take it as the fundamental standard to determine the nature of Marx’s future social outlook.
