In The Practice of Everyday Life Michel de Certeau (1925-1996) discusses Wittgenstein’s model of ordinary language. Certeau points out the primary historical context of Wittgenstein’s thought. This science of the ordinary is defined by foreignness. Wittgenstein himself always remained a foreigner, away from home. Wittgenstein’s position resembles the situation of Labadie the Nomad that Certeau describes in The Mystic Fable. It is the position of the wild mystic.
