Communism, Socialism, Darwinism
Charles Robert Darwin and Karl Heinrich Marx dominated the human mind in the second half of the 19th century making Marxism and Darwinism much debated theories.
Marxism and Darwinism follows the theory of evolution, Darwinism, upon the domain of the organic world (things animate); Marxism, upon the domain of society. Earlier, Hegel made it the central point of his philosophy.
Darwin's The Origin of Species (theory of evolution), was immediately accepted as a strongly proved truth, linking the theory of evolution with Darwins name.
Darwin discovered the mechanism of animal development, and he showed that under certain conditions some animal kinds will necessarily develop into other animal-kinds.
Karl Heinrich Marx discovered the propelling force, the cause of social development. Marx did not have to prove that such a development was taking place; every one knew that from the most primitive times new social forms ever supplanted older.
In Marxism and Darwinism, Marxism owes its importance and position to the role it takes in the proletarian class struggle. Darwinism deals with a new scientific truth which has to contend with religious prejudices and ignorance.
Marxist ideas claim that each historical period has a distinct mode of production that rests upon particular forces - or technological organization - of production and distinct ways of organizing social relationships between people in the economy.
