(a) Historical materialism, (b) Alienation, (c) Class antagonism.

(a) Historical materialism : It refers to the developmental outcome of the material activity of a man over nature which in turn determines other social institutions of man.

(b) Alienation : It is a condition of self-estrangement, consequently the worker is detached from the work. Alienation takes place in the broken relationship between workers and work (or the process of production).

(c) Class antagonism : It means class struggle. Class antagonism is the central theme of the writings of Karl Marx. He wrote, history of all the hitherto existing societies is the history of class struggle. Antagonism exists between the oppressor and the oppressed which polarise the two blocks, i.e., the Bourgeoisie and Proletariat.
