The theoretical struggle is a key component of the class struggle. As Lenin explained, without revolutionary theory there can be no revolutionary movement. Capitalism is facing the deepest crisis in its history. The ruling class can offer no real way forward for the vast majority of people. 

That is the reason they spread a whole array of confused and reactionary ideas. Racism, sexism and all forms of oppression are used, along with the ideas of postmodernism in all its guises, to divide and confuse working-class people and youth – to turn us against each other and atomise the class struggle. Some of these ideas are openly reactionary. Others are given a ‘radical’ cloak.

Engels explained that, alongside the economic and political struggle, there was the equally important struggle for theory. The In Defence of Marxism magazine is joining this struggle, as a tool and a weapon for revolutionary class fighters all over the world, offering serious Marxist analysis on theoretical questions and burning issues of the labour movement. Only the ideas of genuine Marxism can act as a guide to action in the struggle to overthrow capitalism on a world scale.
