Some have argued that Derrida's work took a political and ethical "turn" in the 1990s. Texts cited as evidence of such a turn include "Force of Law" (1990), as well as "Specters of Marx" (1994) and "Politics of Friendship" (1994). Some refer to "The Gift of Death" as evidence that he began more directly applying deconstruction to the relationship between ethics and religion. In this work, Derrida interprets passages from the Bible, particularly on Abraham and the Sacrifice of Isaac, and from Søren Kierkegaard's "Fear and Trembling".
