"Marx's Theory of Alienation" is Allman's important work on Marx's dialectics, alienation theory and human studies, covering topics such as human nature, private ownership, division of labor, commodities and value. This book points out that social reality is the basic element of Marx's research. It refers to relationships rather than objects. It is necessary to use dialectics based on the philosophy of internal relationships to study the concept of human nature and alienation theory in capitalist society. Human beings have dual natures in capitalist society. On the one hand, they are natural attributes based on strength and needs, corresponding to natural persons; on the other hand, they are social attributes closely related to social needs such as production and communication, corresponding to social persons. In this book, Allman integrates Marx's theory of man and society through alienation theory. He not only discusses the four provisions of alienation theory based on Marx's early literature, but also extends the influence of alienation theory to mature works, discussing the important role of value (relationship) as alienated labor in defining various elements of the superstructure such as commodity fetishism, class, country, religion, and ideology. It has important theoretical value.
