Jacques Derrida indicates that when it comes to discourse, not only speech is necessary to come to mind but should also be contained in writing. To poststructuralists, language and discourse are quite important: object, subject, states, material structures etc. are constructed through the language. Unlike positivist claims, language is not a tool that is used for registration of data. Discourses are not only constative but are also performative. So you do/constitute something while you say something. For instance, sovereign states are constructed by discoursive practices, such as security discourse, immigration policies, policymakers’ discourse about national interest, economic invesment, threat, danger or existence of foreigners in their countries etc. Hence, in poststructuralist thought, discourse not only describes the world but also constructs it. As can be understood from the information given, the correct answer is E. All statements in the answer choices can be used to strengthen the argument that “Discourses are not only constative but are also performative” in the context of poststructualism.
