Fuery explores the relationship between post-structuralism and absence. In order to understand the psychoanalytic theory of Lacan (and Freud), the deconstructionalist methodology of Derrida, Foucault's studies of systems of thought, and Kristeva's socio-cultural and psychoanalytic interests, Fuery believes it is necessary to take into consideration the function and operation of absence. He shows how post-structuralist theory can be seen as a system of studies of subjectivity in terms of absence, and how desire is based almost entirely on the precondition of absence. The study is divided into sections on subjectivity. desire, and meaning, with the final section working toward a hermeneutics and semiotics of absence.
