Introduction Myths of interiority, from the critique of one myth to that of another?

This introduction defines and thematizes political solipsism (the myth of interiority being one of its versions) by analogy with metaphysical solipsism. We target here the isolation of the state from other states and not only the isolation of the individual. State solipsism, i.e. ignorance of the foreign, is a specific problem, to be distinguished from nationalism. Can we then refute it in the same way as metaphysical solipsism? What can be the role of Wittgenstein’s philosophy of language?
