Roquentin says of physical objects that, for them, "to exist is simply to be there." When he has the revelation at the chestnut tree, this "fundamental absurdity" of the world does not go away. What changes then is his attitude. By recognizing that objects won't supply meaning in themselves, but people must supply it for them – that Roquentin himself must create meaning in his own life – he becomes both responsible and free. The absurdity becomes, for him, "the key to existence."
