Elaz„±„¸ for The chapter encourages readers to weigh the merits and shortcomings of both ideological and ironic lenses, to identify their uses within the history of political thought, and to explore the nature of an appropriate balance. chapter 1 Theory and Vision IN SUBSEQUENT CHAPTERS we investigate the nature of politics and political life. Before doing so, however, it is useful to explore our proposed method of investigation. That is to say, we first need to explore the nature of theory itself and the various ways of theorizing. The best way to conceive of theory is to think of it as a kind of lens. We all have lenses in our eyes that focus light on our retinas. Many people also wear optical lenses made of glass or plastic to correct poor vision. Elaz„±„¸ 2016.
