“Political words and notions and acts are not intelligible save in the context of the issues that divide the men who use them. Consequently our own attitudes and activities are likely to remain obscure to us, unless we understand the dominant issues of our own world. The greatest of these is the open war that is being fought between two systems of ideas which return different and conflicting answers to what has long been the central question of politics–the question of obedience and coercion ‘Why should I (or anyone) obey anyone else?’ `Why should I not live as I like?’ `Must I obey?’ `If I disobey, may I be coerced ? By whom, and to what degree, and in the name of what, and for the sake of what?'”
