On the battle of Ideas
"The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force. The class which has the means of material production at its disposal has control at the same time over the means of mental production, so that thereby, generally speaking, the ideas of those who lack the means of mental production are subject to it. The ruling ideas are nothing more than the ideal expression of the dominant material relationships, the dominant material relationships grasped as ideas."
Karl Marx, The German Ideology, 1845
The 13th Congress of the Party was spot on in bringing the question of the ‘battle of ideas' to the fore.
Indeed the issue of who dominates the public discourse is as old as the post 1994 democractic society. Before 1994 it was clear that only two ideologies prevailed, i.e. capitalism and racism. Others may argue that racism in itself cannot stand as an ideology. By the way, racism was institutionalised in South Africa in the manner that its legislation was made alive through permeation into everyday life of South Africans.
So you need to think again before trivialising it to any phenomenon less than an ideology. This is why it's a mountain to climb even now in eradicating the philosophy of racism that was entrenched in our educational, cultural, religious and economic system. The SACP characterised this systematic deepening of racist ideology coupled with capitalism long ago as "Colonialism of a Special Type (CST)'.
The CST theory basically in its simplistic terms points out a unique type of colonialism whereby the oppressor and the oppressed share one territory. The privileged white minority wanted to impose their norms, values, racial and economic superiority on the majority of the South African populace. This they did by co-opting some in the oppressed communities into conniving with their ideology so as share in the spoils of elitism.
