Psychoanalysis

[derrida]

Psychoanalysis is certainly alive and well, but nowadays its usefulness exists more as a research tool in uncovering and tracing the trajectories of cultural artifacts and symptomologies. Slavoj Zizek, using the methods of Lacan, is probably its most well-known practioner.

OAO- I think Marxist theoretical tools, particularly the concepts of reification and commodity fetishism, are more than adequate in describing conditions of postmodernity.
