Even if one is not an actual immigrant or expatriate, it is still possible to think as one, to imagine and investigate in spite of barriers, and always to move away from the centralizing authorities towards the margins where you see things that are usually lost on minds that have never traveled beyond the conventional and comfortable....[T]o be as marginal and undomesticated as someone who is in real exile is for an intellectual to be unusually responsive to the traveler rather than the potentate, to the provisional and risky rather than the habitual, to innovation and experiment than the authoritatively given status quo. (Edward Said)
