"To think of a scientific object is still for us to think of a ghostly physical object; that is to say, to think of something to which scientific thought is increasingly inapplicable. Hence, the difficulty for the layman of modern physics".
Bruno Latour

"Meanings are common social beliefs, sometimes mutually contradictory and historically rooted, rather than undated and theoretically fixed constructs." Eco
