Full Idea
The immediate task of philosophy, which is at the service of history, once the holy form of self-estrangement has been unmasked, is to unmask self-estrangement in its unholy form.
Gist of Idea
Once religion is unmasked, the task of philosophy is to unmask other types of self-estrangement

A Reaction
I take it that this means that the first task is to deconstruct religious beliefs, and the second is to deconstruct cognitive bias. I find the image of unbiased philosophers smugly unmasking all the pathetic masked people very unattractive.
