P. is a professional philosopher whose Parliamentary seat allows him to observe real-life politics after having spent so much of his life studying its theory, but he soon realizes that the realpolitik hardly corresponds to his preconceived notions of politics. His only ally in negotiating this disheartening conundrum is his alter ego, the ghost, with whom he spends the duration of this book discussing the tensions and maladjustments brought about by this contrast. "P. es un filosofo de profesion cuya obtencion de un escano en el Parlamento le permite observar en persona como es en la realidad aquella politica a la que ha dedicado tantas horas de estudio teorico. Desde su posicion se da cuenta de que la realpolitik apenas corresponde con las prenociones que albergaba de la politica. Como unico aliado para negociar este abismo, P. se apoya en su alter ego, el fantasma, con quien comenta y discute a lo largo del libro la friccion o el desajuste producidos por este contraste.
