I asked him about this quote from J. Z. Smith; he replied that he was correct, religion is a constructed category, but that didn’t mean it wasn’t also real. So Latour takes the constructionist agenda of the post-structuralists a step further. Our categories are indeed invented, but not “merely” so, for they are also real. They become real through our wielding of them.
“The foundation of irreligious criticism is: Man makes religion, religion does not make man. Religion is indeed the self-consciousness and self-esteem of man who has either not yet won through to himself or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man, state, society. This state and this society produce religion, which is an inverted consciousness of the world, because they are an inverted world.”
