Open Marxism

Open Marxism is a collection of critical and heterodox Marxist schools of thought which critique state socialism and party politics, stressing the need for openness to praxis and history through an anti-positivist method grounded in the "practical reflexivity" of Karl Marx's own concepts. The "openness" in open Marxism also refers to a non-deterministic view of history in which the unpredictability of class struggle is foregrounded.

It is very strongly anti-structuralist in both its Marxism–Leninist and Althusserian forms, and there is significant overlap with some schools of post-Marxism. It often (though not always) aligns itself with humanist Marxism, and libertarian or left communism.
