Karl Marx authored 'Das Kapital' (Capital), a foundational text in critical theory and political economy. In this work, he provides a comprehensive analysis of the capitalist mode of production, exploring concepts such as commodity fetishism, surplus value, and the exploitation of labor within a class-based society.

Karl Marx was deeply influenced by Georg Wilhelm Friedrich Hegel's dialectical method, which posits that history progresses through the conflict of opposing forces (thesis, antithesis, and synthesis). Marx adapted this 'idealist' dialectic into 'dialectical materialism,' arguing that the material conditions of production, rather than ideas, are the primary drivers of historical change and social conflict.

Marx famously described religion as the 'opium of the people.' He argued that religion serves as a form of alienation, where individuals project their human essence onto a divine being, thereby losing control over their own lives and accepting their subordinate position in the capitalist system as divinely ordained, which prevents them from challenging their exploitation.

Pure sociology is traditionally defined as the pursuit of sociological knowledge for the sake of understanding social phenomena, rather than for immediate practical application. However, there is a notable conflict here: the provided answer 'Practical use' contradicts the standard academic definition of 'Pure' sociology, which is usually contrasted with 'Applied' sociology. This suggests a potential misunderstanding in the source material regarding the distinction between pure and applied research paradigms.

Herbert Spencer, a prominent 19th-century English philosopher and sociologist, authored 'The Principles of Ethics' as part of his comprehensive 'System of Synthetic Philosophy'. His work applied evolutionary principles to social life and moral development, significantly influencing early sociological thought regarding the nature of society and human progress.
