Criticism of Marxism (also known as Anti-Marxism) has come from various political ideologies and academic disciplines. This includes general intellectual criticism about dogmatism, a lack of internal consistency, criticism related to materialism (both philosophical and historical), arguments that Marxism is a type of historical determinism or that it necessitates a suppression of individual rights, issues with the implementation of communism and economic issues such as the distortion or absence of price signals and reduced incentives. In addition, empirical and epistemological problems are frequently identified.
