Christian existentialist philosophers, such as Gabriel Marcel, argued for a conception of the human individual not as an isolated subjectivity, as in Descartes’ cogito, but as born into and shaped by its relationships with others. ‘Being’ is necessarily ‘being with’. Spark’s plots dramatise, in characters such as Jean Brodie, the dangers of an isolating subjectivity that seeks to make the world conform to its own wishes in order to deny the fact they have been ‘thrown’ into a world they did not choose. In defiance of Sartre’s emphasis on the ability of human beings to choose their own future, Spark’s novels emphasise the historical and geographic ‘thrownness’ of her characters, their accidental arrival in situations they did not choose. These may be the geographical flashpoints of modern history, such as the Palestine of The Mandelbaum Gate, or the temporal eruption of the past into the present, as in Territorial Rights. It is this fundamental lack of control that leads Spark to insist that ridicule must be central to contemporary art, since ridicule not only challenges religious, political and ideological efforts to control events but challenges the presumptions of art itself when it seeks to shape the world.
